    Scaling AI Means Scaling Interconnects

    This article is part two in a series on talks delivered at Accelerated Infrastructure for the AI Era, a one-day symposium held by Marvell in April 2024.

    Interconnects have played a key role in enabling technology since the dawn of computing. During World War II, Alan Turing used the Turing machine to perform mathematical computations to break the Nazi’s code. This fast—at least at the time—computer used a massive parallel system and numerous interconnects. Eighty years later, interconnects play a similar role for AI—providing a foundation for massively parallel problems. However, with the growth of AI comes unique networking challenges—and Marvell is poised to meet the needs of this ever-growing market.

    What’s driving interconnect growth?
    Before 2023, the interconnect world was a different place. Interconnect speeds were driven by the pace of cloud data center server upgrades: the upgrades occurred every four years so the speed of interconnects doubled every four years at the same time. In 2023, generative AI took the interconnect wheel, and demand for AI is driving speeds to double every two years. And, while copper remains a viable technology for chip-to-chip and other short reach connections, optical is the dominant medium for AI.

    “Optical is the only technology that can give you the bandwidth and reach needed to connect hundreds and thousands and tens of thousands of servers across the whole data center,” said Dr. Loi Nguyen, executive vice president and general manager of Cloud Optics at Marvell. “No other technology can do the job—except optical.”

    AI doubles interconnect speed in half the time

    The AI Opportunity at Marvell

    Two trillion dollars. That’s the GDP of Italy. It’s the rough market capitalization of Amazon, of Alphabet and of Nvidia. And, according to analyst firm Dell’Oro, it’s the amount of AI infrastructure CAPEX expected to be invested by data center operators over the next five years. It’s an historically massive investment, which begs the question: Does the return on AI justify the cost?

    The answer is a resounding yes.

    AI is fundamentally changing the way we live and work. Beyond chatbots, search results, and process automation, companies are using AI to manage risk, engage customers, and speed time to market. New use cases are continuously emerging in manufacturing, healthcare, engineering, financial services, and more. We’re at the beginning of a generational inflection point that, according to McKinsey, has the potential to generate $4.4 trillion in annual economic value. 

    In that light, two trillion dollars makes sense. It will be financed through massive gains in productivity and efficiency.

    Our view at Marvell is that the AI opportunity before us is on par with that of the internet, the PC, and cloud computing. “We’re as well positioned as any company in technology to take advantage of this,” said chairman and CEO Matt Murphy at the recent Marvell Accelerated Infrastructure for the AI Era investor event in April 2024.

    Cryptomathic and Marvell: Enhancing Crypto Agility for the Cloud

    By Bill Hagerstrand, Director of Security Solutions at Marvell

    Grab a cup of coffee. In this blog I describe how IT professionals can utilize Marvell® LiquidSecurity® Hardware Security Modules (HSMs) with Cryptomathic’s Crypto Service Gateway.

    Cryptomathic has 35+ years of experience providing global secure solutions to a variety of industries, including banking, government, technology manufacturing, cloud, and mobile. The company’s Crypto Service Gateway software is a first-of-its-kind central cryptographic platform that provides centralized and crypto-agile management of third party HSM hardware, enhancing the behavior of HSMs while improving the time-to-market of business applications.

    An HSM is a physically secure computing device that safeguards and manages digital keys, performs encryption/decryption functions, and provides strong authentication mechanisms. They typically come in two form factors: a PCIe card or a 1U network attached server. They are NIST (National Institute of Standards and Technology) FIPS 140-3, level-3 certified and most provide tamper evidence (visible signs of tampering), tamper resistance (the HSM becomes inoperable upon tampering) or tamper responsive (deletion of keys upon tamper detection). All provide logging and alerting features, strong authentication, and key management features, and support common APIs like PKCS#11. Applications that require cryptographic services will make API calls for keys used to encrypt data in motion or at rest.

    The Big, Hidden Problem with Encryption and How to Solve It

    By Bill Hagerstrand, Director of Security Solutions at Marvell

    Data encryption, invented nearly 50 years ago1, remains one of our most valuable tools for securing data.

    It is also woefully under-utilized.

    The most recent Entrust-Ponemon survey shows that 62% of enterprises have an encryption strategy in place, which is another way of saying 38% don’t2. (In 2021, it was 49%3.). 美国 Department of Health and Human Services imposes millions in fines per year on healthcare organizations for improper snooping of medical records by employees, or health records accidentally released when a doctor’s laptop gets stolen. And, although 60% got hit with ransomware attacks this year, only 24% were able to thwart an attack by encrypting it before the hackers could.

    So, what’s the hang up?

    Inertia. For all of its effectiveness, encryption has historically been difficult and/or inconvenient to use (in part, of course, for the need to keep access tight.) It requires cooperation between both the sender and receiver and adds additional processing power and time. How many of your personal emails or messages do you encrypt? One of the most widespread and successful uses of encryption in the consumer world—encrypting the data for financial transactions on phones—has succeeded in part because it takes the encryption process out of the hands of consumers and makes it a back-end function. Back-end encryption functions, meanwhile, are also typically performed on a hardware security module (HSM), a 1U to 2U appliance that companies historically kept on premise and maintained on their own.

    Self-Destructing Encryption Keys and Static and Dynamic Entropy in One Chip

    By Eric Hunt-Schroeder, Senior Staff Manager, Digital IC Design, Marvell

    From ISSCC to GOMACTech, we’re presenting new and exciting technology solutions that will benefit the aerospace and defense industry. 

    For anyone who’s watched the 1990s cartoon, Inspector Gadget, the phrase “This message will self-destruct” is bound to be familiar. Anytime Inspector Gadget is given a new assignment, he receives a message containing critical information and instructions. Inspector Gadget must act quickly because shortly after opening, the message is promptly blown to smithereens. 

    Recently, I had the opportunity to present self-destructing encryption key technology within microchips during the Institute of Electrical and Electronics Engineers (IEEE) International Solid-State Circuits Conference (ISSCC) hosted in San Francisco from February 18 to 22. If the chip or keys become compromised, the keys self-destruct. Essentially, we’ve created security on the fly—the Inspector Gadget way. We received a significant amount of media attention from publications such as IEEE Spectrum and Tom’s Hardware

    But we didn’t stop with ISSCC. Shortly after, I had the opportunity to attend the GOMACTech conference where I presented our reconfigurable physically unclonable function (PUF) and random number generation technology—all in one chip. This technology promises to be critical for the aerospace and defense industry.

    Dual Use IP: Shortening Government Development Cycles from Two Years to Six Months

    By Aidan Kelly, Senior Principal Engineer, Solutions Architect at Marvell Government Solutions

    Just like its civilian counterparts, the government uses semiconductors to enable all critical systems. Moreso than its civilian counterparts, the government uses semiconductors for system which can expose those semiconductors to extreme conditions and in addition have highly stringent requirements for security. With lives, safety, and national security on the line, the government can’t afford for these chips to fail.  

    As demand for chips that meet government specs increases, so do the costs associated with developing these highly technical and specific chips, particularly as the government works to integrate rapidly developing applications, such as artificial intelligence (AI). 

    But here’s the problem: chips that meet the government’s stringent specifications cannot be developed in a day, so by the time they complete what can be a long development and testing process, they may be eclipsed by newer technology.

    So how can the government get the advanced chips they need and get them quickly enough to keep up with ever-changing technology?

    O-Band Coherent: An Idea Whose Time Is (Nearly) Here

    By Xi Wang, VP of Product Marketing of Optical Connectivity, Marvell

    Over the last 20 years, data rates for optical technology have climbed 1000x while power per bit has declined by 100x, a stunning trajectory that in many ways paved the way for the cloud, mobile Internet and streaming media.

    AI represents the next inflection point in bandwidth demand. Servers powered by AI accelerators and GPUs have far greater bandwidth needs than typical cloud servers: seven high-end GPUs alone can max out a switch that ordinarily can handle 500 cloud two-processor servers.  Just as important, demand for AI services, and higher-value AI services such as medical imaging or predictive maintenance, will further drive the need for more bandwidth. The AI market alone is expected to reach $407 billion by 2027. 

    O-band coherent or coherent lite—a technology that has been discussed for years at conferences but has yet to be deployed commercially in a meaningful way--will likely begin to percolate into the market over the next few years to help cloud service providers accommodate some of these challenges.

    光学技术将如何拯救云

    作者:Marvell 光学平台高级副总裁兼首席技术官 Radha Nagarajan

    This article was first published by Photonics Spectra

    The cloud. It evokes an ethereal, weightless environment where problems get whisked away by a breeze.

    In reality, the cloud consists of massive industrial buildings containing millions of dollars’ worth of equipment spread over thousands, and increasingly millions, of square feet. In Arizona, some communities are complaining that cloud data centers are draining their aquifers and consuming far more water than expected1 while in the UK and Ireland the power requirements of data centers are crimping needed housing development. Even in regions like Northern Virginia where the local economies are tightly bound to data centers, conflicts between residents and the cloud are emerging.

    With the rise of AI, these conflicts will escalate. AI models and data sets are growing exponentially in size2 and developers are contemplating clusters with 32,000 GPUs, 2,000 switches, 4,000 servers and 74,000 optical modules3. Such a system might require 45MW of power capacity, or nearly 5x the peak load of the Empire State Building. This resource-intensiveness also shows how AI services could become an economic high wire act for many.

    Performance up, Power Down: Over 20 years, the data rate of optical modules has increased by 1000x while power per bit has decreased by 100x.

    How PCIe Interconnect is Critical for the Emerging AI Era

    By Annie Liao, Product Management Director, Connectivity, Marvell

    PCIe has historically been used as protocol for communication between CPU and computer subsystems. It has gradually increased speed since its debut in 2003 (PCI Express) and after 20 years of PCIe development, we are currently at PCIe Gen 5 with I/O bandwidth of 32Gbps per lane. There are many factors driving the PCIe speed increase. The most prominent ones are artificial intelligence (AI) and machine learning (ML). In order for CPU and AI Accelerators/GPUs to effectively work with each other for larger training models, the communication bandwidth of the PCIe-based interconnects between them needs to scale to keep up with the exponentially increasing size of parameters and data sets used in AI models. As the number of PCIe lanes supported increases with each generation, the physical constraints of the package beachfront and PCB routing put a limit to the maximum number of lanes in a system. This leaves I/O speed increase as the only way to push more data transactions per second. The compute interconnect bandwidth demand fueled by AI and ML is driving a faster transition to the next generation of PCIe, which is PCIe Gen 6.

    PCIe has been using 2-level Non-Return-to-Zero (NRZ) modulation since its inception. Increasing PCIe speed up to Gen 5 has been achieved through doubling of the I/O speed. For Gen 6, PCI-SIG decided to adopt Pulse-Amplitude Modulation 4 (PAM4), which carries 4-level signal encoding 2 bits of data (00, 01, 10, 11). The reduced margin resulting from the transition of 2-level signaling to 4-level signaling has also necessitated the use of Forward Error Correction (FEC) protection, a first for PCIe links. With the adoptions of PAM4 signaling and FEC, Gen 6 marks an inflection point for PCIe both from signaling and protocol layer perspectives. 

    In addition to AI/ML, disaggregation of memory and storage is an emerging trend in compute applications that has a significant impact in the applications of PCIe based interconnect. PCIe has historically been adopted on-board and for in-chassis interconnects. Attaching more front-facing NVMe SSDs is one of the common PCIe interconnect examples. With the increasing trends toward flexible resource allocation, and the advancement of CXL technology, the server industry is now moving toward disaggregated and composable infrastructure. In this disaggregated architecture, the PCIe end points are located at different chassis away from the PCIe root complex, requiring the PCIe link to travel out of the system chassis. This is typically achieved through direct attach cables (DAC) that can range up to 3-5m.

    Sustainability as an Opportunity for Semiconductor Product Innovation

    By Alua Suleimenova, ESG Program Manager, Marvell

    The annual United Nations Climate Change Conference COP28 taking place this year in Dubai has brought technology under the sustainability spotlight. In an era of rapid technological advancement, digitalization and proliferation of AI, environmental impacts of technology cannot be overlooked. The semiconductor industry is now at a unique juncture: the global demand for semiconductor products is growing rapidly alongside increasing pressure to reduce greenhouse gas (GHG) emissions.

    Reducing emissions from semiconductor product manufacturing remains the most effective and preferred response measure to climate change for many companies. At the same time, addressing upstream climate impacts alone would not represent a comprehensive picture. Semiconductor companies are increasingly embracing sustainable product design and prioritize power reduction both intrinsically in the products themselves and extrinsically - by collaborating with their customers around energy efficiency in the data infrastructure systems in which the semiconductor products are deployed.

    光纤通道: 关键任务共享存储连接的优选

    By Todd Owens, Director, Field Marketing, Marvell

    Here at Marvell, we talk frequently to our customers and end users about I/O technology and connectivity. This includes presentations on I/O connectivity at various industry events and delivering training to our OEMs and their channel partners. Often, when discussing the latest innovations in Fibre Channel, audience questions will center around how relevant Fibre Channel (FC) technology is in today’s enterprise data center. This is understandable as there are many in the industry who have been proclaiming the demise of Fibre Channel for several years. However, these claims are often very misguided due to a lack of understanding about the key attributes of FC technology that continue to make it the gold standard for use in mission-critical application environments.

    From inception several decades ago, and still today, FC technology is designed to do one thing, and one thing only: provide secure, high-performance, and high-reliability server-to-storage connectivity. While the Fibre Channel industry is made up of a select few vendors, the industry has continued to invest and innovate around how FC products are designed and deployed. This isn’t just limited to doubling bandwidth every couple of years but also includes innovations that improve reliability, manageability, and security.

    走近 AI 时代下的 Marvell 光学技术与创新

    By Kristin Hehir, Senior Manager, PR and Marketing, Marvell

    The sheer volume of data traffic moving across networks daily is mind-boggling almost any way you look at it. During the past decade, global internet traffic grew by approximately 20x, according to the International Energy Agency. One contributing factor to this growth is the popularity of mobile devices and applications: Smartphone users spend an average of 5 hours a day, or nearly 1/3 of their time awake, on their devices, up from three hours just a few years ago. The result is incredible amounts of data in the cloud that need to be processed and moved. Around 70% of data traffic is east-west traffic, or the data traffic inside data centers. Generative AI, and the exponential growth in the size of data sets needed to feed AI, will invariably continue to push the curb upward.

    Yet, for more than a decade, total power consumption has stayed relatively flat thanks to innovations in storage, processing, networking and optical technology for data infrastructure. The debut of PAM4 digital signal processors (DSPs) for accelerating traffic inside data centers and coherent DSPs for pluggable modules have played a large, but often quiet, role in paving the way for growth while reducing cost and power per bit.

    Marvell at ECOC 2023

    At Marvell, we’ve been gratified to see these technologies get more attention. At the recent European Conference on Optical Communication, Dr. Loi Nguyen, EVP and GM of Optical at Marvell, talked with Lightwave editor in chief, Sean Buckley, on how Marvell 800 Gbps and 1.6 Tbps technologies will enable AI to scale.

    数据中心的改头换面

    By Dr. Radha Nagarajan, Senior Vice President and Chief Technology Officer, Optical and Cloud Connectivity Group, Marvell

    This article was originally published in Data Center Knowledge

    People or servers? 

    Communities around the world are debating this question as they try to balance the plans of service providers and the concerns of residents.  

    Last year, the Greater London Authority told real estate developers that new housing projects in West London may not be able to go forward until 2035 because data centers have taken all of the excess grid capacity1EirGrid2 said it won’t accept new data center applications until 2028. Beijing3 and Amsterdam have placed strict limits on new facilities. Cities in the southwest and elsewhere4, meanwhile, are increasingly worried about water consumption as mega-sized data centers can use over 1 million gallons a day5.  

    When you add in the additional computing cycles needed for AI and applications like ChatGPT, the outline of the conflict becomes more heated.  

    On the other hand, we know we can’t live without them. Modern society, with remote work, digital streaming and modern communications all depend on data centers. Data centers are also one of sustainability’s biggest success stories. Although workloads grew by approximately 10x in the last decade with the rise of SaaS and streaming, total power consumption stayed almost flat at around 1% to 1.5%6 of worldwide electricity thanks to technology advances, workload consolidation, and new facility designs. Try and name another industry that increased output by 10x with a relatively fixed energy diet?

    IP over WDM 终于来了吗?

    By Loi Nguyen, Executive Vice President, Cloud Optics Business Group, Marvell

    Some twenty years ago the concept of IP over Wavelength Division Multiplexing (WDM) was proposed as a way to simplify the optical infrastructures. In this vision, all optical networks are connected via point-to-point mesh networks with a router at the center. The concept was elegant, but never took off because the optical technology at the time was not able to keep up with the faster innovation cycle of CMOS, driven by Moore’s law. The larger form factor of WDM optics does not allow them to be directly plugged into a router port. Adopting a larger form factor on the router in order to implement IP over WDM in a massive scale would be prohibitively expensive.

    For routers to interface with the networks, a “transponder” is needed, which is connected to a router via short-reach optics on one side and WDM optics to the network on the other. The market for transponders grew quickly to become a multi-billion-dollar market.

    A Star is Born

    About 10 years ago, I was building a team at Inphi, where I was a co-founder, to further develop a nascent technology called silicon photonics. SiPho, as it’s called, leverages commercial CMOS foundries to develop photonics integrated circuits (PIC) that integrate hundreds of components ranging from high-speed modulators and detectors to passive devices such as couplers, waveguides, monitoring diodes, attenuators and so on. We were looking for ideas and customers to bring silicon photonics to the marketplace.

    Fortunately, good technology and market need found one another. A group of Microsoft executives had been considering IP over WDM to launch a new concept of “distributed data centers,” in which multiple data centers in a region are connected by high speed WDM optics using the same form factor as shorter reach “client optics” used in switches and routers. By chance, we met at ECOC 2013 in London for the initial discussion, and then some months later, a product that enabled IP over WDM at cloud scale was born.

    Product security is paramount to us: A response to recent Cavium product security concerns 

    By Raghib Hussain, President, Products and Technologies, Marvell

    To our Valued Customers:

    Recently, reports have surfaced alleging that certain Cavium products included a “backdoor” for the National Security Agency (NSA). We assure you that neither Cavium nor Marvell have ever knowingly incorporated or retained any vulnerability or backdoor in our products.

    Our products implement a suite of standards-based security algorithms like AES, 3DES, SHA etc. Prior to 2014, some of our software libraries included an algorithm for random number generation called Dual_EC_DRGB. This algorithm was one of four officially recommended at the time by the US National Institute for Standards and Technology (NIST) that our products implemented. In 2013, this algorithm was reported by the New York Times, The Guardian, and ProPublica to include a backdoor for the NSA. After we learned of the potential issue, Cavium removed this algorithm from its software libraries and has not included it in any product shipped since then. 

    Importantly, the Dual_EC_DRGB algorithm was included in some of Cavium’s software libraries for our chip-level products, but not in the chips themselves.  As a result, while Cavium provided this algorithm (among many), the ultimate choice and control over the algorithms being used was managed by the equipment vendors integrating our products into their system level products. Many companies, not just Cavium, implemented the NIST standard algorithms including this algorithm. In fact, according to NIST’s historical validation data, approximately 80 different products with semiconductors from different vendors implemented this algorithm in some combination of hardware, software, and firmware before it was removed.

    汽车中央交换机: 汽车进化的最新进展

    By Amir Bar-Niv, VP of Marketing, Automotive Business Unit, Marvell

    When you hear people refer to cars as “data centers on wheels,” they’re usually thinking about how an individual experiences enhanced digital capabilities in a car, such as streaming media on-demand or new software-defined services for enhancing the driving experience.

    But there’s an important implication lurking behind the statement. For cars to take on tasks that require data center-like versatility, they need to be built like data centers. Automakers in conjunction with hardware makers and software developers are going to have to develop a portfolio of highly specialized technologies that work together, based around similar architectural concepts, to deliver the capabilities needed for the software-defined vehicle while at the same time keeping power and cost to a minimum. It’s not an easy balancing act.

    Which brings us to the emergence of a new category of products for the zonal architecture, specifically zonal and the associated automotive central Ethernet switches. Today’s car networks are built around domain localized networks: speakers, video screens and other infotainment devices link to the infotainment ECU, while powertrain and brakes are part of the body domain, and ADAS domain is based on the sensors and high-performance processors. Bandwidth and security can be form-fitted to the application.

    800G: 光网络的一个拐点

    By Samuel Liu, Senior Director, Product Line Management, Marvell

    Digital technology has what you could call a real estate problem. Hyperscale data centers now regularly exceed 100,000 square feet in size. Cloud service providers plan to build 50 to 100 edge data centers a year and distributed applications like ChatGPT are further fueling a growth of data traffic between facilities. Similarly, this explosive surge in traffic also means telecommunications carriers need to upgrade their wired and wireless networks, a complex and costly undertaking that will involve new equipment deployment in cities all over the world.

    Weaving all of these geographically dispersed facilities into a fast, efficient, scalable and economical infrastructure is now one of the dominant issues for our industry.

    Pluggable modules based on coherent digital signal processors (CDSPs) debuted in the last decade to replace transponders and other equipment used to generate DWDM compatible optical signals. These initial modular products didn’t offer the same performance as the incumbent solutions, and could only be deployed in limited use cases. These early modules, with their large form factors, had performance limitations and did not support the required high-density data transmission. Over time, advances in technology optimized the performance of pluggable modules, and CDSP speeds grew from 100 to 200 and 400 Gbps. Continued innovation, and the development of an open ecosystem, helped expand the potential applications.

    FC-NVMe 成为 HPE 下一代块存储的主流

    By Todd Owens, Field Marketing Director, Marvell

    While Fibre Channel (FC) has been around for a couple of decades now, the Fibre Channel industry continues to develop the technology in ways that keep it in the forefront of the data center for shared storage connectivity. Always a reliable technology, continued innovations in performance, security and manageability have made Fibre Channel I/O the go-to connectivity option for business-critical applications that leverage the most advanced shared storage arrays.

    A recent development that highlights the progress and significance of Fibre Channel is Hewlett Packard Enterprise’s (HPE) recent announcement of their latest offering in their Storage as a Service (SaaS) lineup with 32Gb Fibre Channel connectivity. HPE GreenLake for Block Storage MP powered by HPE Alletra Storage MP hardware features a next-generation platform connected to the storage area network (SAN) using either traditional SCSI-based FC or NVMe over FC connectivity. This innovative solution not only provides customers with highly scalable capabilities but also delivers cloud-like management, allowing HPE customers to consume block storage any way they desire – own and manage, outsource management, or consume on demand.HPE GreenLake for Block Storage powered by Alletra Storage MP

    At launch, HPE is providing FC connectivity for this storage system to the host servers and supporting both FC-SCSI and native FC-NVMe. HPE plans to provide additional connectivity options in the future, but the fact they prioritized FC connectivity speaks volumes of the customer demand for mature, reliable, and low latency FC technology.

    人工智能与数据基础设施的结构转变

    By Michael Kanellos, Head of Influencer Relations, Marvell

    AI’s growth is unprecedented from any angle you look at it. The size of large training models is growing 10x per year. ChatGPT’s 173 million plus users are turning to the website an estimated 60 million times a day (compared to zero the year before.). And daily, people are coming up with new applications and use cases. 

    As a result, cloud service providers and others will have to transform their infrastructures in similarly dramatic ways to keep up, says Chris Koopmans, Chief Operations Officer at Marvell in conversation with Futurum’s Daniel Newman during the Six Five Summit on June 8, 2023. 

    “We are at the beginning of at least a decade-long trend and a tectonic shift in how data centers are architected and how data centers are built,” he said.  

    The transformation is already underway. AI training, and a growing percentage of cloud-based inference, has already shifted from running on two-socket servers based around general processors to systems containing eight more GPUs or TPUs optimized to solve a smaller set of problems more quickly and efficiently.

    我们准备好迎接大规模人工智能工作量了吗?

    By Noam Mizrahi, Executive Vice President, Chief Technology Officer, Marvell

    Originally published in Embedded

    ChatGPT has fired the world’s imagination about AI. The chatbot can write essays, compose music, and even converse in different languages. If you’ve read any ChatGPT poetry, you can see it doesn’t pass the Turing Test yet, but it’s a huge leap forward from what even experts expected from AI just three months ago. Over one million people became users in the first five days, shattering records for technology adoption.

    The groundswell also strengthens arguments that AI will have an outsized impact on how we live—with some predicting AI will contribute significantly to global GDP by 2030 by fine-tuning manufacturing, retail, healthcare, financial systems, security, and other daily processes.

    But the sudden success also shines light on AI’s most urgent problem: our computing infrastructure isn’t built to handle the workloads AI will throw at it. The size of AI networks grew by 10x per year over the last 5 years. By 2027 one in five Ethernet switch ports in data centers will be dedicated to AI, ML and accelerated computing.

    您的 5G 网络有多安全?

    By Bill Hagerstrand, Security Solutions BU, Marvell

    New Challenges and Solutions in an Open, Disaggregated Cloud-Native World

    Time to grab a cup of coffee, as I describe how the transition towards open, disaggregated, and virtualized networks – also known as cloud-native 5G – has created new challenges in an already-heightened 4G-5G security environment.

    5G networks move, process and store an ever-increasing amount of sensitive data as a result of faster connection speeds, mission-critical nature of new enterprise, industrial and edge computing/AI applications, and the proliferation of 5G-connected IoT devices and data centers. At the same time, evolving architectures are creating new security threat vectors. The opening of the 5G network edge is driven by O-RAN standards, which disaggregates the radio units (RU), front-haul, mid-haul, and distributed units (DU). Virtualization of the 5G network further disaggregates hardware and software and introduces commodity servers with open-source software running in virtual machines (VM’s) or containers from the DU to the core network.

    As a result, these factors have necessitated improvements in 5G security standards that include additional protocols and new security features. But these measures alone, are not enough to secure the 5G network in the cloud-native and quantum computing era. This blog details the growing need for cloud-optimized HSMs (Hardware Security Modules) and their many critical 5G use cases from the device to the core network.

    Nova 介绍:针对下一代 AI/ML 系统中高性能光纤优化的 1.6T PAM4 DSP

    By Kevin Koski, Product Marketing Director, Marvell

    Last week, Marvell introduced Nova™, its latest, fourth generation PAM4 DSP for optical modules. It features breakthrough 200G per lambda optical bandwidth, which enables the module ecosystem to bring to market 1.6 Tbps pluggable modules. You can read more about it in the press release and the product brief.

    In this post, I’ll explain why the optical modules enabled by Nova are the optimal solution to high-bandwidth connectivity in artificial intelligence and machine learning systems.

    Let’s begin with a look into the architecture of supercomputers, also known as high-performance computing (HPC).

    Historically, HPC has been realized using large-scale computer clusters interconnected by high-speed, low-latency communications networks to act as a single computer. Such systems are found in national or university laboratories and are used to simulate complex physics and chemistry to aid groundbreaking research in areas such as nuclear fusion, climate modeling and drug discovery. They consume megawatts of power.

    The introduction of graphics processing units (GPUs) has provided a more efficient way to complete specific types of computationally intensive workloads. GPUs allow for the use of massive, multi-core parallel processing, while central processing units (CPUs) execute serial processes within each core. GPUs have both improved HPC performance for scientific research purposes and enabled a machine learning (ML) renaissance of sorts. With these advances, artificial intelligence (AI) is being pursued in earnest.

    Introducing the 51.2T Teralynx 10, the Industry’s Lowest Latency Programmable Switch

    By Amit Sanyal, Senior Director, Product Marketing, Marvell

    If you’re one of the 100+ million monthly users of ChatGPT—or have dabbled with Google’s Bard or Microsoft’s Bing AI—you’re proof that AI has entered the mainstream consumer market.

    And what’s entered the consumer mass-market will inevitably make its way to the enterprise, an even larger market for AI. There are hundreds of generative AI startups racing to make it so. And those responsible for making these AI tools accessible—cloud data center operators—are investing heavily to keep up with current and anticipated demand.

    Of course, it’s not just the latest AI language models driving the coming infrastructure upgrade cycle. Operators will pay equal attention to improving general purpose cloud infrastructure too, as well as take steps to further automate and simplify operations.

    Teralynx 10

    To help operators meet their scaling and efficiency objectives, today Marvell introduces Teralynx® 10, a 51.2 Tbps programmable 5nm monolithic switch chip designed to address the operator bandwidth explosion while meeting stringent power- and cost-per-bit requirements. It’s intended for leaf and spine applications in next-generation data center networks, as well as AI/ML and high-performance computing (HPC) fabrics.

    A single Teralynx 10 replaces twelve of the 12.8 Tbps generation, the last to see widespread deployment. The resulting savings are impressive: 80% power reduction for equivalent capacity.

    Wind River 和 Marvell 携手为 CSP 扩展虚拟 RAN 解决方案

    By Kim Markle, Director Influencer Relations, Marvell

    Wind River and Marvell have collaborated to create an open, virtualized Radio Access Network (vRAN) solution for communication service providers (CSPs) that offers cloud scalability with the features, performance, and energy efficiency of established 5G networks. The collaboration integrates two complementary, industry-leading technologies—the Marvell® OCTEON® 10 Fusion 5G baseband processor and the Wind River Studio cloud software—to provide the carrier ecosystem a deployment-ready vRAN platform built on technologies that are widely proven in 5G networks and data centers.  

    CSPs aim to leverage established IT infrastructure for enhanced service agility and streamlined DevOps in the cloud-native RAN. Marvell's OCTEON 10 Fusion processor supports these goals with programmability based on open-source, industry-standard interfaces and integration with leading cloud software platforms such as Wind River Studio.

    To ensure open-source distribution of Wind River Studio software, OCTEON 10 Fusion software drivers are being used by StarlingX, an open development and integration project. Marvell’s drivers enable Wind River Studio software to communicate with and control the OCTEON 10 Fusion processor. This facilitates developer access to an optimized vRAN system that offers new options for CSPs and helps to expand the carrier ecosystem of RAN and data center hardware and software suppliers, as well as system integrators.

    Marvell 和 VMware 合作优化 RAN

    By Peter Carson, Senior Director Solutions Marketing, Marvell and Tosin Olopade, Technical Product Line Manager, VMware and Padma Sudarsan, Director of Engineering, RAN Architecture, VMware

    VMware, a pioneer in assisting communication service providers (CSPs) in transforming their networks, is partnering up with Marvell, a leading provider of data infrastructure semiconductor solutions to improve RAN performance and ROI. This collaboration provides solutions that enable CSPs to meet the demands of 5G’s increased capacity and use cases, optimizing the revenue and efficiency of each RAN site.

    RAN sites worldwide are targeted for new technology deployment, where traditional, custom-made equipment is being replaced with servers adapted from data centers. This transformation to virtualized RAN and Open RAN, which replaces hardware with software, is driving the modernization of RAN sites worldwide. This allows CSPs to select servers and software based on their strategic goals, enabling them to offer unique services compared to their competitors. 

    However, 5G RAN workloads, particularly Layer 1 (L1), are far more complex and latency-sensitive than the applications that general purpose CPUs have been designed to address. The load on even the most robust CPUs in the case of 5G RAN virtualization can be demanding. The rapid increase in 5G network speeds, reaching multi-gigabit-per-second, and the management of software-centric RAN Distributed Units (DUs) has resulted in rising energy consumption and cooling demands. This leads to increased costs, such as higher electricity bills, and may compromise CSPs’ plans to monetize their RAN investments.

    Marvell 和 Aviz Networks 合作推动 SONiC 在云和企业数据中心的部署

    By Kant Deshpande, Director, Product Management, Marvell

    Disaggregation is the future
    Disaggregation—the decoupling of hardware and software—is arguably the future of networking. Disaggregation lets customers select best-of-breed hardware and software, enabling rapid innovation by separating the hardware and software development paths.

    Disaggregation started with server virtualization and is being adapted to storage and networking technology. In networking, disaggregation promises that any networking operating system (NOS) can be integrated with any switch silicon. Open source-standards like ONIE allow a networking switch to load and install any NOS during the boot process.

    SONiC: the Linux of networking OS
    Software for Open Networking in Cloud (SONiC) has been gaining momentum as the preferred open-source cloud-scale network operating system (NOS).

    In fact, Gartner predicts that by 2025, 40% of organizations that operate large data center networks (greater than 200 switches) will run SONiC in a production environment.[i] According to Gartner, due to readily expanding customer interest and a commercial ecosystem, there is a strong possibility SONiC will become analogous to Linux for networking operating systems in next three to six years.

    下一代数据中心网络化需要做的三件事

    By Amit Sanyal, Senior Director, Product Marketing, Marvell

    Data centers are arguably the most important buildings in the world. Virtually everything we do—from ordinary business transactions to keeping in touch with relatives and friends—is accomplished, or at least assisted, by racks of equipment in large, low-slung facilities.

    And whether they know it or not, your family and friends are causing data center operators to spend more money. But it’s for a good cause: it allows your family and friends (and you) to continue their voracious consumption, purchasing and sharing of every kind of content—via the cloud.

    Of course, it’s not only the personal habits of your family and friends that are causing operators to spend. The enterprise is equally responsible. They’re collecting data like never before, storing it in data lakes and applying analytics and machine learning tools—both to improve user experience, via recommendations, for example, and to process and analyze that data for economic gain. This is on top of the relentless, expanding adoption of cloud services.

    在工业网络中使用时敏网络实现网络可见性

    By Zvi Shmilovici Leib, Distinguished Engineer, Marvell

    Industry 4.0 is redefining how industrial networks behave and how they are operated. Industrial networks are mission-critical by nature and have always required timely delivery and deterministic behavior. With Industry 4.0, these networks are becoming artificial intelligence-based, automated and self-healing, as well. As part of this evolution, industrial networks are experiencing the convergence of two previously independent networks: information technology (IT) and operational technology (OT). Time Sensitive Networking (TSN) is facilitating this convergence by enabling the use of Ethernet standards-based deterministic latency to address the needs of both the IT and OT realms.

    However, the transition to TSN brings new challenges and requires fresh solutions for industrial network visibility. In this blog, we will focus on the ways in which visibility tools are evolving to address the needs of both IT managers and those who operate the new time-sensitive networks.

    Why do we need visibility tools in industrial networks? 

    Networks are at the heart of the industry 4.0 revolution, ensuring nonstop industrial automation operation. These industrial networks operate 24/7, frequently in remote locations with minimal human presence. The primary users of the industrial network are not humans but, rather, machines that cannot “open tickets.” And, of course, these machines are even more diverse than their human analogs. Each application and each type of machine can be considered a unique user, with different needs and different network “expectations.”

    软件定义车辆的软件定义网络

    By Amir Bar-Niv, VP of Marketing, Automotive Business Unit, Marvell and John Heinlein, Chief Marketing Officer, Sonatus and Simon Edelhaus, VP SW, Automotive Business Unit, Marvell

    The software-defined vehicle (SDV) is one of the newest and most interesting megatrends in the automotive industry. As we discussed in a previous blog, the reason that this new architectural—and business—model will be successful is the advantages it offers to all stakeholders:

    • The OEMs (car manufacturers) will gain new revenue streams from aftermarket services and new applications;
    • The car owners will easily upgrade their vehicle features and functions; and
    • The mobile operators will profit from increased vehicle data consumption driven by new applications.

    What is a software-defined vehicle? While there is no official definition, the term reflects the change in the way software is being used in vehicle design to enable flexibility and extensibility. To better understand the software-defined vehicle, it helps to first examine the current approach.

    Today’s embedded control units (ECUs) that manage car functions do include software, however, the software in each ECU is often incompatible with and isolated from other modules. When updates are required, the vehicle owner must visit the dealer service center, which inconveniences the owner and is costly for the manufacturer.

    真正了不起的黑客 – 赢得 SONiC 用户满意

    By Kishore Atreya, Director of Product Management, Marvell

    Recently the Linux Foundation hosted its annual ONE Summit for open networking, edge projects and solutions. For the first time, this year’s event included a “mini-summit” for SONiC, an open source networking operating system targeted for data center applications that’s been widely adopted by cloud customers. A variety of industry members gave presentations, including Marvell’s very own Vijay Vyas Mohan, who presented on the topic of Extensible Platform Serdes Libraries. In addition, the SONiC mini-summit included a hackathon to motivate users and developers to innovate new ways to solve customer problems. 

    So, what could we hack?

    At Marvell, we believe that SONiC has utility not only for the data center, but to enable solutions that span from edge to cloud. Because it’s a data center NOS, SONiC is not optimized for edge use cases. It requires an expensive bill of materials to run, including a powerful CPU, a minimum of 8 to 16GB DDR, and an SSD. In the data center environment, these HW resources contribute less to the BOM cost than do the optics and switch ASIC. However, for edge use cases with 1G to 10G interfaces, the cost of the processor complex, primarily driven by the NOS, can be a much more significant contributor to overall system cost. For edge disaggregation with SONiC to be viable, the hardware cost needs to be comparable to that of a typical OEM-based solution. Today, that’s not possible.

    必不可少: 汽车互联互通史的过去和未来

    By Amir Bar-Niv, VP of Marketing, Automotive Business Unit, Marvell and Mark Davis, Senior Director, Solutions Marketing, Marvell

    In the blog, Back to the Future – Automotive network run at speed of 10Gbps, we discussed the benefits and advantages of zonal architecture and why OEMs are adopting it for their next-generation vehicles. One of the biggest advantages of zonal architecture is its ability to reduce the complexity, cost and weight of the cable harness. In another blog, Ethernet Camera Bridge for Software-Defined Vehicles, we discussed the software-defined vehicle, and how using Ethernet from end-to-end helps to make that vehicle a reality.

    While in the near future most devices in the car will be connected through zonal switches, cameras are the exception. They will continue to connect to processors over point-to-point protocol (P2PP) links using proprietary networking protocols such as low-voltage differential signaling (LVDS), Maxim’s GMSL or TI’s FPD-Link.

    TSN 和 Prestera DX1500: 跨越 IT/OT 鸿沟的桥梁

    By Reza Eltejaein, Director, Product Marketing, Marvell

    Manufacturers, power utilities and other industrial companies stand to gain the most in digital transformation. Manufacturing and construction industries account for 37 percent of total energy used globally*, for instance, more than any other sector. By fine-tuning operations with AI, some manufacturers can reduce carbon emission by up to 20 percent and save millions of dollars in the process.

    Industry, however, remains relatively un-digitized and gaps often exist between operational technology – the robots, furnaces and other equipment on factory floors—and the servers and storage systems that make up a company’s IT footprint. Without that linkage, organizations can’t take advantage of Industrial Internet of Things (IIoT) technologies, also referred to as Industry 4.0. Of the 232.6 million pieces of fixed industrial equipment installed in 2020, only 10 percent were IIoT-enabled.

    Why the gap? IT often hasn’t been good enough. Plants operate on exacting specifications. Engineers and plant managers need a “live” picture of operations with continual updates on temperature, pressure, power consumption and other variables from hundreds, if not thousands, of devices. Dropped, corrupted or mis-transmitted data can lead to unanticipated downtime—a $50 billion year problem—as well as injuries, blackouts, and even explosions.

    To date, getting around these problems has required industrial applications to build around proprietary standards and/or complex component sets. These systems work—and work well—but they are largely cut off from the digital transformation unfolding outside the factory walls.

    The new Prestera® DX1500 switch family is aimed squarely at bridging this divide, with Marvell extending its modern borderless enterprise offering into industrial applications. Based on the IEEE 802.1AS-2020 standard for Time-Sensitive Networking (TSN), Prestera DX1500 combines the performance requirements of industry with the economies of scale and pace of innovation of standards-based Ethernet technology. Additionally, we integrated the CPU and the switch—and in some models the PHY—into a single chip to dramatically reduce power, board space and design complexity.

    Done right, TSN will lower the CapEx and OpEx for industrial technology, open the door to integrating Industry 4.0 practices and simplify the process of bringing new equipment to market.

    与汽车黑客的竞赛正在加速

    By Hari Parmar, Senior Principal Automotive System Architect, Marvell

    “In your garage or driveway sits a machine with more lines of code than a modern passenger jet. Today’s cars and trucks, with an internet link, can report the weather, pay for gas, find a parking spot, route around traffic jams and tune in to radio stations from around the world. Soon they’ll speak to one another, alert you to sales as you pass your favorite stores, and one day they’ll even drive themselves.

    While consumers may love the features, hackers may love them even more.”

    The New York Times, March 18, 2021

    Hacking used to be an arcane worry, the concern of a few technical specialists. But with recent cyberattacks on pipelines, hospitals and retail systems, digital attacks have suddenly been thrust into public consciousness, leading many to wonder: are cars at risk, too?

    Not if Marvell can help it. As a leading supplier of automotive silicon, the company has been intensely focused on identifying and securing potential vulnerabilities before they can remotely compromise a vehicle, its driver or passengers.

    Unfortunately, hacking cars isn’t just theoretical – in 2015, researchers on a laptop commandeered a Jeep Cherokee 10 miles away, shutting off power, blasting the radio, turning on the AC and making the windshield wipers go berserk. And today, seven years later, millions more cars – including most new vehicles – are connected to the cloud.

    云存储和内存的演变

    By Gary Kotzur, CTO, Storage Products Group, Marvell and Jon Haswell, SVP, Firmware, Marvel

    The nature of storage is changing much more rapidly than it ever has historically. This evolution is being driven by expanding amounts of enterprise data and the inexorable need for greater flexibility and scale to meet ever-higher performance demands.

    If you look back 10 or 20 years, there used to be a one-size-fits-all approach to storage. Today, however, there is the public cloud, the private cloud, and the hybrid cloud, which is a combination of both. All these clouds have different storage and infrastructure requirements. What’s more, the data center infrastructure of every hyperscaler and cloud provider is architecturally different and is moving towards a more composable architecture. All of this is driving the need for highly customized cloud storage solutions as well as demanding the need for a comparable solution in the memory domain.

    Marvell Brightlane Technology 携手 OMNIVISION 合作伙伴亮相 AutoSens 布鲁塞尔展会

    By Katie Maller, Senior Manager, Public Relations, Marvell

    Building on our leadership in Ethernet camera bridge technology, Marvell is excited to work with OMNIVISION and to have been a part of their automotive demonstrations at the recent AutoSens Brussels event. OMNIVISION, a leading global developer of semiconductor solutions, partnered with Marvell to demonstrate its OX03F10 (image sensor) and OAX4000 (image signal processor) with our industry first multi-gigabit Ethernet camera bridge, the Marvell® Brightlane™ 88QB5224.

    The combined solutions allow camera video that would otherwise be transported via point-to-point protocol to be encapsulated over Ethernet, thereby integrating cameras into the Ethernet-based in-vehicle network. The solutions work with both interior and exterior cameras and are ideal for SVS and other applications in which numerous cameras are utilized and the output of those cameras is used by multiple subsystems or zones.

    “Ethernet is the foundation of the software-defined vehicle. By using the Ethernet camera bridge from our Brightlane automotive portfolio to connect cameras to the zonal Ethernet switch, the cameras are integrated into the end-to-end, in-vehicle network,” said Amir Bar-Niv, vice president of marketing for Marvell’s automotive business unit. “Standard Ethernet features such as security, switching, and synchronization are now available to the camera system, and a simple software update is all that’s required when porting the system from one automobile model to another. Shorter runs to the zonal switches reduce the cable cost and weight, as well.”

    The demonstrations in the OMNIVISION booth were well received at AutoSens Brussels, an annual event that brings together leading engineers and technical experts from across the ADAS and autonomous vehicle supply chain.

    SONiC: It’s Not Just for Switches Anymore

    By Amit Sanyal, Senior Director, Product Marketing, Marvell

    SONiC (Software for Open Networking in the Cloud) has steadily gained momentum as a cloud-scale network operating system (NOS) by offering a community-driven approach to NOS innovation. In fact, 650 Group predicts that revenue for SONiC hardware, controllers and OSs will grow from around US$2 billion today to around US$4.5 billion by 2025. 

    Those using it know that the SONiC open-source framework shortens software development cycles; and SONiC’s Switch Abstraction Interface (SAI) provides ease of porting and a homogeneous edge-to-cloud experience for data center operators. It also speeds time-to-market for OEMs bringing new systems to the market.

    The bottom line: more choice is good when it comes to building disaggregated networking hardware optimized for the cloud. Over recent years, SONiC-using cloud customers have benefited from consistent user experience, unified automation, and software portability across switch platforms, at scale.

    As the utility of SONiC has become evident, other applications are lining up to benefit from this open-source ecosystem.

    A SONiC Buffet: Extending SONiC to Storage

    SONiC capabilities in Marvell’s cloud-optimized switch silicon include high availability (HA) features, RDMA over converged ethernet (RoCE), low latency, and advanced telemetry. All these features are required to run robust storage networks.

    Here’s one use case: EBOF. The capabilities above form the foundation of Marvell’s Ethernet-Bunch-of-Flash (EBOF) storage architecture. The new EBOF architecture addresses the non-storage bottlenecks that constrain the performance of the traditional Just-a-Bunch-of-Flash (JBOF) architecture it replaces-by disaggregating storage from compute.

    EBOF architecture replaces the bottleneck components found in JBOF - CPUs, DRAM and SmartNICs - with an Ethernet switch, and it’s here that SONiC is added to the plate. Marvell has, for the first time, applied SONiC to storage, specifically for services enablement, including the NVMeoFTM (NVM Express over Fabrics) discovery controller, and out-of-band management for EBOF, using Redfish® management. This implementation is in production today on the Ingrasys ES2000 EBOF storage solution. (For more on this topic, check out thisthis, and this.)

    Marvell has now extended SONiC NOS to enable storage services, thus bringing the benefits of disaggregated open networking to the storage domain.

    OK, tasty enough, but what about compute?

    How Would You Like Your Arm Prepared?

    I prefer Arm for my control plane processing, you say. Why can’t I manage those switch-based processors using SONiC, too, you ask? You’re in luck. For the first time, SONiC is the OS for Arm-based, embedded control plane processors, specifically the control plane processors found on Marvell® Prestera® switches. SONiC-enabled Arm processing allows SONiC to run on lower-cost 1G systems, reducing the bill-of-materials, power, and total cost of ownership for both management and access switches.

    In addition to embedded processors, with the OCTEON® family, Marvell offers a smorgasbord of Arm-based processors. These can be paired with Marvell switches to bring the benefits of the Arm ecosystem to networking, including Data Processing Units (DPUs) and SmartNICs.

    By combining SONiC with Arm processors, we’re setting the table for the broad Arm software ecosystem - which will develop applications for SONiC that can benefit both cloud and enterprise customers.

    The Third Course

    So, you’ve made it through the SONiC-enabled switching and on-chip control processing courses but there’s something more you need to round out the meal. Something to reap the full benefit of your SONiC experience. PHY, of course. Whether your taste runs to copper or optical mediums; PAM or coherent modulation, Marvell provides a complete SONiC-enabled portfolio by offering SONiC with our (not baked) Alaska® Ethernet PHYs and optical modules built using Marvell DSPs.  Room for Dessert?

    Finally, by enabling SONiC across the data center and enterprise switch portfolio we’re able to bring operators the enhanced telemetry and visibility capabilities that are so critical to effective service-level validation and troubleshooting. For more information on Marvell telemetry capabilities, check out this short video:

     

    The Drive Home

    Disaggregation has lowered the barrier-to-entry for market participants - unleashing new innovations from myriad hardware and software suppliers. By making use of SONiC, network designers can readily design and build disaggregated data center and enterprise networks.

    For its part, Marvell’s goal is simple: help realize the vision of an open-source standardized network operating system and accelerate its adoption.

    针对工业和边缘应用优化 SSD

    By Pichai Balaji, Director, Product Marketing, Flash BU, Marvel

    Industrial SSDs are specifically designed for high-performance systems where data integrity and reliability are of the utmost importance. Industrial SSDs cover a wide range of applications including industrial data storage, heavy robotics, retail kiosks, medical systems, security surveillance, video monitoring, and gaming, to name a few.

    When most people hear the term “industrial SSD,” they immediately think of a ruggedized, high-temperature SSD in a metal casing. While such drives are part of the industrial class of SSDs, most industrial and edge applications have a wider range of requirements in terms of SSD controller hardware, firmware, SSD form factor, drive capacity, endurance, reliability, and use case/workload.

    For these applications, it is critical that the SSD meets industrial quality standards, and long-term reliability and performance requirements. These SSD devices must be able to withstand industrial grade temperatures, as well as a higher level of shock and vibration. Some applications need these SSDs to operate in ambient temperatures ranging from -40°C to 85°C. In such extreme conditions, data loss is a serious concern.

    Marvell’s 88SS1321/22 SSD controllers are designed to meet the industrial requirements on temperature endurance, longevity, and performance. Marvell’s 88SS1321 device also provides flexibility for the industrial SSD maker to choose the SSD form factor (supports 2.5” / U.2; m.2 2230 to 22110), and  choose to use the SSD with or without DRAM (optional).

    Exascend recently launched an industrial grade PCIe Gen 4 SSD – the PI4 Series. Powered by Marvell’s 88SS1321 PCIe Gen 4 SSD controller, the SSD offers 3500MB/s performance and can operate in an extreme temperature range of -40°C to 85°C. It offers full disk encryption / TCG OPAL 2.0 in M.2 (2280 & 2242), U.2, E1.S and CFexpress form factors for industrial and ADAS storage applications.

    Marvell’s 88SS1321/22 SSD controller hardware is designed to offer SSD firmware the maximum control to optimize SSD level solutions for different workloads in a wide range of industrial and edge applications. The product’s reference design has been validated from standards/spec compliance, as well as from an electrical compatibility perspective. The board design BOM is also cost-optimized for low cost of ownership. More information on these benefits can be found here.

    Additionally, various SKUs within the product offer added flexibility to SSD makers, enabling them to address applications that may require DRAM and a wider range of operating temperatures.

    With the integration of AI/ML, industrial systems have become autonomous and more distributed in recent years. The proliferation of AI-based IoT (AIoT) devices has increased end-to-end system complexity, pushing compute and storage resources to the edge in order to leverage low-latency 5G connectivity and/or Ethernet Time Sensitive Networking (TSN) for real-time, mission-critical data access and processing.

    Innodisk is another industrial SSD maker who has recently launched multiple PCIe Gen 4 industrial-grade SSDs with Marvell’s 88SS1321/22 SSD controllers that can operate with or without DRAM. The Innodisk PCIe 4TE and 4TG-P are the first industrial-oriented PCIe 4.0 SSDs turbocharging 5G and AIoT. The product can work in -40°C and 85°C environments, where some specific applications, including smart streetlights, 5G mmWave, and security inspection cameras, are critical for industrial strength. The PCIe 4TE and 4TG-P support AES-256 encryption and are TCG-OPAL 2.0 compliant.

    Other key features of Marvell’s industrial SSD controllers include:

    • Support for both DRAM and in DRAM-less operation
    • Support for a wide range of form factors, including m.2 110 to 30, CFexpress and BGA SSD
    • SDK firmware to kickstart the development and customization of the SSD for the end-user application/workload
    • Offered in C-temp (0°C-70°C) and I-temp (-40°C-85°C) SKUs

    Marvell’s 88SS1321/22 SSD controllers are designed to allow firmware to be optimized for many different applications. A host of SKUs built on the same architecture allow SSD developers to leverage Marvell’s reference design to develop their own SSD for various form factors, capacity, endurance, and reliability standards including ruggedized, high-temp SSDs with metal casings.

    用于软件定义车辆的以太网摄像机桥接

    By Amir Bar-Niv, VP of Marketing, Automotive Business Unit, Marvell

    Automotive Transformation

    Smart Car and Data Center-on-wheels are just some of the terms being used to define the exciting new waves of technology transforming the automotive industry and promising safer, greener self-driving cars and enhanced user experiences. Underpinning it all is a megatrend towards Software-defined Vehicles (SDV). SDV is not just a new automotive technology platform. It also enables a new business model for automotive OEMs. With a software-centric architecture, car makers will have an innovation platform to generate unprecedented streams of revenue from aftermarket services and new applications. For owners, the capability to receive over-the-air software updates for vehicles already on the road – as easily as smartphones are updated – means an automobile whose utility will no longer decline over time and driving experiences that can be continuously improved over time.

    这篇博客是一系列博客中的第一篇,这一系列博客将讨论实现 SDV 未来的系统的基本组件。

    Road to SDV is Paved with Ethernet

    A key technology to enable SDVs is a computing platform that is supported by an Ethernet-based In-Vehicle network (IVN). An Ethernet-based IVN provides the ability to reshape the traffic between every system in the car to help meet the requirements of new downloaded applications. To gain the full potential of Ethernet-based IVNs, the nodes within the car will need to “talk” Ethernet. This includes devices such as car sensors and cameras. In this blog, we discuss the characteristics and main components that will drive the creation of this advanced Ethernet-based IVN, which will enable this new era of SDV. 

    But first let’s talk about the promises of this new business model. For example, people might ask, “how many new applications can possibly be created for cars and who will use them?” This is probably the same question that was asked when Apple created the original AppStore, which started with dozens of new apps, and now of course, the rest is history. We can definitely learn from this model. Plus, this is not going to be just an OEM play. Once SDV cars are on the road, we should expect the emergence of new companies that will develop for the OEMs a whole new world of car applications that will be aligned with other megatrends like Smart City, Mobility as a Service (MaaS), Ride-hailing and many others. 

    A New Era of Automotive Innovation

    Let us now fast forward to the years 2025 to 2030 (which in the automotive industry is considered ‘just around the corner.’) New cars that are designed to support higher level of driver assist systems (ADAS) include anywhere between 20 to 30 sensors (camera, radar, lidar and others). Let’s imagine two new potential applications that could utilize these sensors:

    Application 1: “Catch the Car Scratcher” - How many times have we heard of, or even been in, this situation? Someone scratches your car in the parking lot or maliciously scratches your car with a car key. What if the car was able to capture the face of the person or license plate number of the car that caused the damage? Wouldn’t that be a cool feature an OEM could provide to the car owner on demand? If priced right, it most likely could become a popular application. The application could use the accelerometers, and potentially a microphone, to detect the noise of scratching, bumping or hitting the car. Once the car identifies the scratching or bumping, it would activate all of the cameras around the car. The car would then record the video streams into a central storage. This video could later be used by the owner as necessary to recover repair costs through insurance or the courts.

    Application 2: “Break-in Attempt Recording” - In this next application, when the system detects a break-in attempt, all internal and external cameras record the video into central storage and immediately upload it to the cloud. This is done in case the car thief tries to tamper with the storage later. In parallel, the user gets a warning signal or alert by phone so they can watch the video streams or even connect to the sound system in the car and scare the thief with their own voice.

    We will examine these scenarios more comprehensively in a follow up blog, but these are just two simple examples of the many possible high-value automotive apps that an Ethernet-based IVN can enable in the software-defined car of the future.

    Software-Defined Network

    Ethernet network standards comprise a long list of features and solutions that have been developed over the years to address real network needs, including the mitigation of security threats. Ethernet was initially adopted by the automotive industry in 2014 and it has since become the dominant network in the car. Once the car’s processors, sensors, cameras and other devices are connected to each other via Ethernet (Ethernet End-to-End), we can realize the biggest promise of SDV: the capability to reprogram the in-vehicle network and adapt its main characteristics to new advanced applications. This capability is called In-Vehicle Software-Defined Networking, or in short, In-vehicle SDN.

    Figure 1 shows the building blocks for In-Vehicle SDN that enable SDV.Ethernet and SDN as building blocks for SDV

     

    Figure 1 – Ethernet and SDN as building blocks for SDV

    Ethernet features enable four key attributes that are key for SDV: Flexibility, Scalability, Redundancy and Controllability.

    • Flexibility provides for the ability to change data flow in the network and share devices (like cameras and sensors) between domains, processors and other shared resources (e.g., storage).
    • Scalability of both software and hardware is needed to support new applications and features. Software updates to the originally installed processors and ECUs usually require changes in the network’s routing of data and controls. Hardware can be also modified over time in the car, and in many cases, adaptations to the network may be required to support new speeds and Quality of Service (QoS), for the new hardware.
    • Redundancy, not only in mission-critical processors but also in data paths between the devices, safeguards the network. Switching and multi-data paths can also assist load balancing in the backbone of the in-vehicle network.
    • Controllability, diagnostic and real-time debugging of all links in the car provides real-time self-diagnosis and fault management, such as channel quality, link marginality/degradation, and EMC vulnerability, by leveraging of the Ethernet’s Operations, Administration, and Maintenance (OAM) protocol. With advanced, AI/ML based data processing, more effective prediction of network health is possible, enabling higher-level safety goals and significant economic benefits.

    In-vehicle SDN is the mechanism that provide the ability to modify and adapt these attributes in SDV. SDN is a technology that uses application programming interfaces (APIs) to communicate with underlying hardware infrastructure, like switches and bridges, and provisions traffic flow in a network. The In-Vehicle SDN allows the separation of control and data planes and brings network programmability to the realm of advanced data forwarding mechanisms in automotive networks.

    Cameras and the Ethernet Edge

    To realize the full capability of in-vehicle SDN, most devices in the car will need to be connected via Ethernet. In today’s advanced car architectures, the backbone of the high-speed links is all Ethernet. However, camera interfaces are still based on old proprietary point-to-point Low-Voltage Differential Signaling (LVDS) technology. Newer technologies (like MIPI’s A-PHY and ASA) are under development to replace LVDS, but these are still point-to-point solutions. In this blog we refer to all of these solutions as P2PP (Point-to-Point Protocol). In Figure 2, we show an example of a typical zonal car network with the focus on two domains that use the camera sensors: ADAS and Infotainment.Zonal network architecture with point-to-point camera links

     

    Figure 2 – Zonal network architecture with point-to-point camera links

    While most of the ECUs / Sensors / Devices are connected through (and leverage the benefits of) the zonal backbone, cameras are still connected directly (point-to-point) to the processors. Cameras cannot be shared in a simple manner between the two domains (ADAS and IVI), that in many cases are in separate boxes. There is no scalability in this rigid connectivity. Redundancy is also very limited, since the cameras are connected directly to a processor, and any malfunction in this processor might result in lost connection to the cameras.

    One potential “solution” for this is to connect the cameras to the zonal switches via P2PP, as shown in Figure 3. Zonal network architecture with point-to-point camera links to Zonal switch

     

    Figure 3 – Zonal network architecture with point-to-point camera links to Zonal switch

    This proposal solves only a few of the problems mentioned above but comes at a high cost. To support this configuration the system always needs a dedicated Demux chip, as showed in Figure 4, that converts the P2PP back to camera interface. In addition, to support this configuration, the Zonal switches need a dedicated video interface, like MIPI D-PHY. This interface requires 12 pins per camera (4 pairs for data, 1 pair for clock and 1 pair for control (I2C or SPI)). This adds complexity and many dedicated pins which increases system cost. Another option is to use an external Demux-switch (on top of the Zonal switch) to aggregate multiple P2PP lanes, which is expensive.

    Integration of any of these protocols into the Zonal switch is also highly unlikely, since it requires dedicated, non-Ethernet ports on the switch. In addition, no one will consider integration of proprietary or new and non-matured technologies into switches or SoCs.Camera P2PP Bridge in Zonal Architecture

     

    Figure 4 – Camera P2PP Bridge in Zonal Architecture

    Next is controllability, diagnostics and real-time debugging that do not work over the P2PP links in the same simple and standard way they work over Ethernet. This limits the leverage of existing Ethernet-based SW utilities that are used to access, monitor and debug all Ethernet-based ECUs, devices and sensors in the vehicle.

    The right solution for all of these issues is to convert the camera-video to Ethernet – at the edge. A simple bridge device that connects to the camera module and encapsulates the video over Ethernet packets is all it takes, as shown in Figure 5.Ethernet Camera Bridge in Zonal Architecture

     

    Figure 5 – Ethernet Camera Bridge in Zonal Architecture

    Since the in-vehicle Ethernet network is Layer 2 (L2)-based, the encapsulation of camera video over Ethernet requires a simple, hard-coded (meaning no SW) MAC block in the bridge device. Figure 6 shows a network that utilizes such bridge devices.Zonal architecture with Ethernet End-to-End

     

    Figure 6 – Zonal architecture with Ethernet End-to-End

    The biggest advantage of the Ethernet camera bridge is that it leverages the robustness and maturity of the Ethernet standard. For the Ethernet bridge PHY it means a proven technology (2.5G/5G/10GBASE-T1 and soon 25GBASE-T1) with a very strong ecosystem of cables, connectors, and test facilities (compliance, interoperability, EMC, etc.) that have been accepted by the automotive industry for many years.

    But this is only the tip of the iceberg. Once the underlying technology for the camera interface is Ethernet, these links automatically gain access to all the other IEEE Ethernet standards, like:

    • Switching and virtualization - IEEE 802.1
    • Security – authentication and encryption – IEEE 802.1AE MACsec
    • Time-Synchronization over network – IEEE PTP 1588
    • Power over cable – IEEE PoDL 802.3bu
    • Audio/Video Bridging – IEEE 802.1 AVB/TSN
    • Asymmetrical transmission, using Energy Efficient Ethernet protocol – IEEE 802.3az
    • Support for all topologies: Mesh, star, ring, daisy-chain, point-to-point

    These important features for automotive networks are covered in a previous Marvell blog called, “Ethernet Advanced Features for Automotive Applications.”

    The Ethernet End-to-End with Ethernet camera bridges supports all four key attributes (described in Figure 1) that are required for reliable software-defined car operation: Cameras can easily be shared among domains. Software and hardware can be easily modified independently and scaled all the way up to the camera and sensors. No special video interfaces are needed in the zonal switch – the camera Ethernet link is connected to a standard Ethernet port on the switch, and can be routed on multiple paths, for redundancy. This approach offers the full support of controllability, diagnostic and real-time debugging of the camera links using standard Ethernet utilities that are used in the rest of the in-vehicle network.

    So, what’s next? As camera resolutions and refresh rates increase, camera links will need to support future data rates that climb beyond 10Gbps. To support this trend, the IEEE P802.3cy Greater than 10 Gb/s Electrical Automotive Ethernet PHY Task Force is already in the process of defining a standard for 25Gbps automotive PHY. Therefore, we can expect the vehicle backbone as well as Camera Ethernet bridges of up to 25Gbps to be inevitable in the future, and with them, a plethora of even more compelling smart car apps.

    Marvell 与生态系统合作伙伴一起展示了不折不扣的 Open RAN 解决方案,该全新解决方案使用了出众的云无线计算架构

    By Peter Carson, Senior Director Solutions Marketing, Marvell

    Marvell’s 5G Open RAN architecture leverages its OCTEON Fusion processor and underscores collaborations with Arm and Meta to drive adoption of no-compromise 5G Open RAN solutions

    The wireless industry’s no-compromise 5G Open RAN platform will be on display at Mobile World Congress 2022. The Marvell-designed solution builds on its extensive compute collaboration with Arm and raises expectations about Open RAN capabilities for ecosystem initiatives like the Meta Connectivity Evenstar program, which is aimed at expanding the global adoption of Open RAN. Last year at MWC, Marvell announced it had joined the Evenstar program [read more]. This year, Marvell’s new 5G Open RAN Accelerator will be on display at the Arm booth at MWC 2022. The OCTEON Fusion processor, which integrates 5G in-line acceleration and Arm Neoverse CPUs, is the foundation for Marvell’s Open RAN DU reference design.

    5G is going mainstream with the rapid rollout of next generation networks by every major operator worldwide. The ability of 5G to reliably provide high bandwidth and extremely low latency connectivity is powering applications like metaverse, autonomous driving, industrial IoT, private networks, and many more. 5G is a massive undertaking that is set to transform entire industries and serve the world’s diverse connectivity needs for years to come. But the wireless networks at the center of this revolution are, themselves, undergoing a major transformation – not just in feeds and speeds, but in architecture. More specifically, significant portions of the 5G radio access network (RAN) are moving into the cloud.

    不折不扣的 5G Open RAN:计算架构

    By Peter Carson, Senior Director Solutions Marketing, Marvell

    简介

    5G networks are evolving to a cloud-native architecture with Open RAN at the center. This explainer series is aimed at de-mystifying the challenges and complexity in scaling these emerging open and virtualized radio access networks. Let’s start with the compute architecture.

    The Problem 

    Open RAN systems based on legacy compute architectures utilize an excessively high number of CPU cores and energy to support 5G Layer 1 (L1) and other data-centric processing, like security, networking and storage virtualization. As illustrated in the diagram below, this leaves very few host compute resources available for the tasks the server was originally designed to support. These systems typically offload a small subset of 5G L1 functions, such as forward error correction (FEC), from the host to an external FPGA-based accelerator but execute the processing offline. This kind of look-aside (offline) processing of time-critical L1 functions outside the data path adds latency that degrades system performance.Limitations of Open RAN systems based on general purpose processors

    存储网络的新发展: 自动驾驶 SANs

    By Todd Owens, Field Marketing Director, Marvell and Jacqueline Nguyen, Marvell Field Marketing Manager

    Storage area network (SAN) administrators know they play a pivotal role in ensuring mission-critical workloads stay up and running. The workloads and applications that run on the infrastructure they manage are key to overall business success for the company.

    Like any infrastructure, issues do arise from time to time, and the ability to identify transient links or address SAN congestion quickly and efficiently is paramount. Today, SAN administrators typically rely on proprietary tools and software from the Fibre Channel (FC) switch vendors to monitor the SAN traffic. When SAN performance issues arise, they rely on their years of experience to troubleshoot the issues.

    What creates congestion in a SAN anyway?

    Refresh cycles for servers and storage are typically shorter and more frequent than that of SAN infrastructure. This results in servers and storage arrays that run at different speeds being connected to the SAN. Legacy servers and storage arrays may connect to the SAN at 16GFC bandwidth while newer servers and storage are connected at 32GFC.

    Fibre Channel SANs use buffer credits to manage the prioritization of the traffic flow in the SAN. When a slower device intermixes with faster devices on the SAN, there can be situations where response times to buffer credit requests slow down, causing what is called “Slow Drain” congestion. This is a well-known issue in FC SANs that can be time consuming to troubleshoot and, with newer FC-NVMe arrays, this problem can be magnified. But these days are soon coming to an end with the introduction of what we can refer to as the self-driving SAN.

    5G 接入网的光学技术

    By Matt Bolig, Director, Product Marketing, Networking Interconnect, Marvell

    There’s been a lot written about 5G wireless networks in recent years.  It’s easy to see why; 5G technology supports game-changing applications like autonomous driving and smart city infrastructure.  Infrastructure investment in bringing this new reality to fruition will take many years and 100’s of billions of dollars globally, as figure 1 below illustrates.

    Marvell 和 Ingrasys 携手为数据中心使用 EBOF 的 Ceph 集群提供支持

    By Khurram Malik, Senior Manager, Technical Marketing, Marvell

    A massive amount of data is being generated at the edge, data center and in the cloud, driving scale out Software-Defined Storage (SDS) which, in turn, is enabling the industry to modernize data centers for large scale deployments. Ceph is an open-source, distributed object storage and massively scalable SDS platform, contributed to by a wide range of major high-performance computing (HPC) and storage vendors. Ceph BlueStore back-end storage removes the Ceph cluster performance bottleneck, allowing users to store objects directly on raw block devices and bypass the file system layer, which is specifically critical in boosting the adoption of NVMe SSDs in the Ceph cluster. Ceph cluster with EBOF provides a scalable, high-performance and cost-optimized solution and is a perfect use case for many HPC applications. Traditional data storage technology leverages special-purpose compute, networking, and storage hardware to optimize performance and requires proprietary software for management and administration. As a result, IT organizations neither scale-out nor make it feasible to deploy petabyte or exabyte data storage from a CAPEX and OPEX perspective.
    Ingrasys (subsidiary of Foxconn) is collaborating with Marvell to introduce an Ethernet Bunch of Flash (EBOF) storage solution which truly enables scale-out architecture for data center deployments. EBOF architecture disaggregates storage from compute and provides limitless scalability, better utilization of NVMe SSDs, and deploys single-ported NVMe SSDs in a high-availability configuration on an enclosure level with no single point of failure.

    Power Ceph Cluster with EBOF in Data Centers image 1

    Ceph is deployed on commodity hardware and built on multi-petabyte storage clusters. It is highly flexible due to its distributed nature. EBOF use in a Ceph cluster enables added storage capacity to scale up and scale out at an optimized cost and facilitates high-bandwidth utilization of SSDs. A typical rack-level Ceph solution includes a networking switch for client, and cluster connectivity; a minimum of 3 monitor nodes per cluster for high availability and resiliency; and Object Storage Daemon (OSD) host for data storage, replication, and data recovery operations. Traditionally, Ceph recommends 3 replicas at a minimum to distribute copies of the data and assure that the copies are stored on different storage nodes for replication, but this results in lower usable capacity and consumes higher bandwidth. Another challenge is that data redundancy and replication are compute-intensive and add significant latency. To overcome all these challenges, Ingrasys has introduced a more efficient Ceph cluster rack developed with management software – Ingrasys Composable Disaggregate Infrastructure (CDI) Director.

  • October 20, 2021

    By Radha Nagarajan, SVP and CTO, Optical and Copper Connectivity Business Group

    As the volume of global data continues to grow exponentially, data center operators often confront a frustrating challenge: how to process a rising tsunami of terabytes within the limits of their facility’s electrical power supply – a constraint imposed by the physical capacity of the cables that bring electric power from the grid into their data center.

    Fortunately, recent innovations in optical transmission technology – specifically, in the design of optical transceivers – have yielded tremendous gains in energy efficiency, which frees up electric power for more valuable computational work.

    Recently, at the invitation of the Institute of Electrical and Electronics Engineers, my Marvell colleagues Ilya Lyubomirsky, Oscar Agazzi and I published a paper detailing these technological breakthroughs, titled Low Power DSP-based Transceivers for Data Center Optical Fiber Communications.

    利用下一代以太网释放 5G 网络性能

    By Alik Fishman, Director of Product Management, Marvell

    Blink your eyes. That’s how fast data will travel from your future 5G-enabled device, over the network to a server and back. Like Formula 1 racing cars needing special tracks for optimal performance, 5G requires agile networking transport infrastructure to unleash its full potential. The 5G radio access network (RAN) requires not only base stations with higher throughputs and soaring speeds but also an advanced transport network, capable of securely delivering fast response times to mobile end points, whatever those might be: phones, cars or IoT devices. Radio site densification and Massive Machine-type Communication (mMTC) technology are rapidly scaling the mobile network to support billions of end devices1, amplifying the key role of network transport to enable instant and reliable connectivity.

    With Ethernet being adopted as the most efficient transport technology, carrier routers and switches are tasked to support a variety of use cases over shared infrastructure, driving the growth in Ethernet gear installations. In traditional cellular networks, baseband and radio resources were co-located and dedicated at each cell site. This created significant challenges to support growth and shifts in traffic patterns with available capacity. With the emergence of more flexible centralized architectures such as C-RAN, baseband processing resources are pooled in base station hubs called central units (CUs) and distributed units (DUs) and dynamically shared with remote radio units (RUs). This creates even larger concentrations of traffic to be moved to and from these hubs over the network transport.

    The exponential increase in bandwidth demand will drive continuous innovation in, and deployment of, data movement interconnects for Cloud and Telecom providers.  As a result, highly integrated silicon photonics platform solutions are expected to become a key enabling technology for the cloud and telecom market over the next decade.

    What Does Highly Integrated Silicon Photonics Platform Mean for the Infrastructure Business?

    As speed continues to go up, optical will replace copper as the primary conduit of the digital bits inside Cloud data centers.  Marvell is investing heavily in silicon photonics to complement our high-speed CMOS technologies in data center interconnects to accelerate this transition.

    • Silicon photonic solutions have been successfully deployed inside Cloud data centers for 100G to compete with traditional “chip-and-wire” discrete solutions.  We expect silicon photonics will gain market share as the Cloud providers transition to the next bit rate of 400G.
    • Integrated silicon photonics platform solutions have intrinsic advantage over conventional packaging solutions at ever increasing baud rates.
    • Integrating optical components on a silicon interposer can leverage the cost benefits of large-scale automated electronics assembly eco-system versus the traditional “chip-and-wire” optical industry.

    The roots of Ethernet technology began in 1973, when Bob Metcalfe, a researcher at Xerox Research Center (who later founded 3COM), wrote a memo entitled “Alto Ethernet,” which described how to connect computers over short-distance copper cable. With the explosion of PC-based Local Area Networks (LAN) in businesses and corporations in the 1980s, the growth of client/server LAN architectures continued, and Ethernet started to become the connectivity technology of choice for these networks. However, the Ethernet advancement that made it the most successful networking technology ever was when standardization efforts began for it under the IEEE 802.3 group.

    Essential technology, done right - 全新 Marvell,全新启航

    作者:Chris Koopmans,市场营销与业务运营执行副总裁

    
					Chris Koopmans

    Marvell 的转型
    今天,Marvell 推出了全新的品牌标识。 从很多方面来说,它可谓是“千呼万唤始出来”。它既能展现我们在过去四年一路走来的转型历程,也体现出现今的新公司新面貌。

    通常,当企业着手推进重大变革时,首先关注的就是其展现给外界的形象。 企业会更新徽标、网页和宣传材料,以便塑造其品牌形象,然后全力将这种品牌愿景转变为现实。 不过在我们的行业中,一家公司的品牌就是他们的声誉,而声誉是靠日积月累建立起来的。 这便是为何 Marvell 选择从最难之处着手:首先确立新的战略,对业务进行转型,同时改革完善企业文化;现在,我们正着力呈现一个能够体现我们价值观的新品牌。 这一品牌理念也非常好地契合了 Marvell“务实为本”的文化内涵。

    四年前,就在 Matt 接任首席执行官的前几周,我加入了 Marvell,可以说,我一路见证了公司在转型过程中迈出的每一步。 转型期间,我有幸担任多个不同领导职位,这也让我能够从独特的视角来审视公司如今的面貌。 去年,Matt 与我沟通了一项全新挑战,他希望我带领营销团队,重新构建 Marvell 的外部形象,不得不说,这个机会让我感到非常兴奋。

    关注 Marvell 员工与社区

    By Matt Murphy, Chairman and Chief Executive Officer, Marvell

    Matt Murphy President and Chief Executive Officer of Marvell

    如今的世界,与几个月前相比,已经有所不同了。 此次疫情对于我们来说是一场超乎寻常的危机,对于我们的运营系统与价值观来说,都是一场考验。 这场危机还提醒了我们什么更值得珍视,那就是我们与他人的人际关系。 As billions of us shelter in our homes around the clock – working, exercising, educating, and sharing the same space - it is an opportunity to appreciate quality time with our immediate family. 但同时,我们也失去了与其他不在同一屋檐下,也是我们珍爱的人之间的联系,并为那些身体欠佳人的健康与安全感到担忧。 我们无法与同事面对面,只能通过电脑屏幕见面,而不是在走廊或者午餐时间碰面。 我们也失去了很多其他机会,比如在社区内面见朋友、在非常喜欢的餐馆里享受美食、在农贸市场购物,以及在公园内徒步(因其已闭园)。

    分布式和混合式 IT 的数据加密蓝图

    作者:Avishai Ziv,Marvell 安全解决方案事业部总经理

    如果有机会选择,很少有企业会改变其安全解决方案和部署,尤其对于数据加密领域。 这是因为数据加密的任何改变都可能是一项痛苦而又艰巨的任务。 但面临着当今数据安全领域日益增长的威胁,企业真的有选择空间吗?

    非常高的风险

    我们在新闻头条上读到的数据泄露事件往往影响到知名企业数以亿计的客户,而其中大部分都涉及到未加密的数据。 遗憾的是,如此松懈的安全措施在业内普遍存在。 McAfee 近期一项针对 12,000 家公司的调查显示,只有 9% 的公司在云中对静态数据进行加密,只有 1% 的公司使用客户管理的加密密钥。

    Marvell 和 HPE 推出了适用于 HPE ProLiant 和 Apollo Gen10 Plus 服务器的行业标准适配器

    By Todd Owens, Field Marketing Director, Marvell

    创新可以有多种形式。 有时是一项全新的技术,有时是对现有产品的更新,而在其他情况下,则仅仅是改变获取和交付产品的方式。 Hewlett Packard Enterprise (HPE) 在 I/O 连接方面的崭新创新便属于后者。

    在 HPE ProLiant 及 Apollo Gen10 Plus 服务器发布的同时,HPE 服务器 I/O 选择团队开发了一种新的方式,用于为这些服务器寻找和限定以太网适配器。 HPE 部署其所称的行业标准适配器后,在 HPE 服务器以太网适配器的固件和驱动程序更新方面能提供更多选择,更好地满足终端客户需求。

    传统上,HPE 会从诸如 Marvell 等 OEM 供应商处寻求 I/O 技术,为适配器创建客户型号和规格,使固件和驱动器只能从 HPE 获取。 这些“定制”适配器通常被称为 HPE 优化适配器。 以 Gen10 Plus 服务器为开端,HPE 正在取消定制并使用标准适配器,此类适配器不仅可用于 HPE 服务器,还可用于其他服务器。 因此有了术语“行业标准适配器”。

    Marvell 很高兴与 HPE 存在合作,提供多种在 HPE ProLiant Gen10 Plus 服务器上充分合格且受 HPE 支持的 Marvell® FastLinQ® 适配器。 以下是 Marvell 目前为 HPE Gen10 Plus 服务器提供的产品。

    HPE 零件号 型号名称 产品描述
    P08437-B21 QL41132HLRJ HPE 以太网 10Gb 双端口 BASE-T QL41132HLRJ 适配器
    P10103-B21 QL41132HQRJ HPE 以太网 10Gb 双端口 BASE-T QL41132HQRJ OCP3 适配器
    P21933-B21 QL41132HLCU HPE 以太网 10Gb 双端口 SFP+ QL41132HLCU 适配器
    P08452-B21 QL41132HQCU HPE 以太网 10Gb 双端口 SFP+ QL41132HQCU OCP3 适配器
    P10094-B21 QL41134HLCU HPE 以太网 10GbE 四端口 SFP+ QL41134HLCU 适配器
    P22702-B21 QL41232HLCU HPE 以太网 10/25Gb 双端口 SFP28 QL41232HLCU 适配器
    P10118-B21 QL41232HQCU HPE 以太网 10/25Gb 双端口 SFP28 QL41232HQCU OCP3 适配器

    有了新方式,HPE Gen10 Plus 客户可以在 HPE 产品描述中看到 Marvell 型号,并在服务器启动时识别出 Marvell 供应商和产品 ID。 然后可经引导至 Marvell,获取详细说明、用户指南、技术简介,甚至是固件和/或驱动程序下载。  The support model will not change and HPE will continue to provide level 1 - 3 support. 新方式将通过以下几种途径使 HPE 客户受益:

    • 特定产品类型和型号信息的透明性:无需使用复杂的解码器辅助工具或其他文档来确定实际制造商。
    • 操作系统 HCL 的产品/型号命名的一致性,节省多方核对 I/O 和操作系统兼容性的时间。
    • 固件/驱动程序增强功能和更新推向市场的速度更快,使修复程序可以在制造商开始提供时即获得。
    • 能够简化跨多供应商服务器环境的维护流程,并直接从制造商网站获取固件/驱动程序。

    对于那些喜欢使用 HPE 特定部署软件以及实用程序(如 HPE System Insight Manager (SIM)、System Update Manager (SUM) 或 Service Pack for ProLiant (SPP))的 HPE ProLiant 客户,HPE 也将通过其标准季度流程提供固件和驱动程序。 

    Marvell 针对 HPE ProLiant Gen10 Plus 的产品组合包括支持 1/10GBASE-T、10Gb SFP+ 及 10/25GbE SFP28 变体的 PCIe 和 OCP 3.0 形状因数适配器。 所有这些适配器也支持 Marvell 一系列行业排名靠前的特性及功能,包括:

    低延迟是选 RoCE 还是 iWARP?

    By Todd Owens, Field Marketing Director, Marvell

    如今,远程直接内存访问 (RDMA) 已经在高性能计算或云环境中受到广泛采用,以降低整个网络中的延迟。  企业客户很快也将转向 RDMA 才能提供的低延迟网络,以此解决多种不同的应用,如 Oracle 和 SAP,同时还能部署采用 Windows Storage Spaces Direct (S2D) 或 VMware vSAN 的软件定义存储。  在 RDMA 的部署中可以采用三种协议: 基于Infiniband的 RDMA、基于聚合以太网 (RoCE) 的 RDMA 以及基于 iWARP 的 RDMA。  鉴于以上多种可能的发展路径,您如何确保您所选择的协议能够契合您的特定任务?

    在企业领域,目前来看以太网是最常用的传输技术。  Consequently, we can ignore the InfiniBand option, as it would require a forklift upgrade to the I/O existing infrastructure - thus making it way too costly for the vast majority of enterprise data centers.  于是,选择只剩下了 RoCE 和 iWARP。  以上两者都能够在以太网络中提供低延迟连接。  但是哪一款更适合您?

    首先,我们了解一下以上两种协议间的根本区别。  RoCE 是两种协议中最常用的一种,并且已经为全球众多云端超大规模客户所采用。  包括 Marvell 在内的多家供应商均能提供启用 RDMA 运行 RoCE 的适配器。

    RoCE 能够提供 1-5us 范围内的适配器延迟,但要求有无损以太网才能实现低延迟运行。  这意味着集成到网络中的以太网交换机必须支持数据中心桥接(DCB)和优先流控制(PFC)机制,以此才能维持无损流量。  因此要想使用 RoCE 可能需要重新配置以太网交换机。  无损或聚合以太网的难点在于,在现代化的企业环境中,配置是一个复杂的流程,并且可扩展性会受到很大的局限。 iWARP is RDMA over TCP routable with standard ethernet, E2E Flow Control with TCP Congestion Avoidance 尽管大规模采用 RoCE 并非不可能,但需要实施额外的流量拥堵控制机制,例如数据中心量化拥堵通知 (DCQCN),而这反过来又要求配备大量经验丰富的网络工程师与管理员。  虽然超大规模客户有能力实现以上要求,但并非所有企业客户都具备这样的实力。  小规模企业的人力资源和财务预算会受到更多限制。

    回顾聚合以太网环境的历史,要想理解其中所涉及的挑战数量,莫过于研究一下基于以太网的光纤通道 (FCoE)。  五年前,众多分析师和行业专家断言 FCoE 将取代光纤通道在数据中心的地位。  但由于大规模使用聚合以太网络的复杂性,这一预言最终没有成真。  FCoE 仍然存在,但限于 HPE BladeSystem 或 HPE Synergy 刀片类服务器的封闭环境,在这些环境中网络属性和规模都受到严格控制。  此类单跳环境在每一个系统中仅有少量连接。

    最后,我们来谈谈 iWARP。  这一协议的诞生晚于 RoCE,其优势在于能够运行在当今的标准 TCP/IP 网络中。  该协议能够提供 10-15us 范围内的适配器延迟。  这一延迟高于 RoCE 能够达到的数值,但较标准以太网适配器仍然降低了好几个数量级。

    常言道,对于只有一把锤子的人来说,他遇见的每样东西看起来都像一颗钉子。  对于推销启用了 RDMA 的适配器的供应商来说也是同样的道理。  大多数供应商只支持一种协议,因此他们理所当然就会推荐他们支持的这一种协议。  而在 Marvell,我们的独特之处在于,借助我们的通用 RDMA 技术,客户能够在同一个适配器上同时使用 RoCE 和 iWARP。  这使得我们提出的建议更具可信度,这也意味着我们有效地做到了不对协议有任何偏见。  从客户的立场来说这一点非常重要,这意味着我们专注于寻找非常适合于客户应用标准的协议。

    那么您究竟应该在什么样的场景下使用哪种 RDMA?  这么说吧,如果延迟是您的首要标准,而可扩展性可以抛诸脑后,那么您应当选择 RoCE。  您可以将 RoCE 部署成现代化磁盘阵列中的后端网络,介于控制器节点和 NVMe 驱动器之间。  您也可以将 RoCE 部署在机架中或仅占有一台或两台架顶式交换机和子网的机架中。  相对地,如果延迟只是关键要求之一,而易于使用和可扩展性也具有高优先级,那么 iWARP 就是杰出候选方案。  该协议能够运行在现有的网络基础设施中,并且能够轻松在机架间扩展规模,甚至能够在数据中心间远距离部署。   iWARP 的典型用例就是部署了 Microsoft Storage Spaces Direct 的网络连接方案。

    好消息是对于企业客户而言,有多款 HPE 出品的 Marvell® FastLinQ® 以太网适配器支持通用 RDMA,因此企业客户能够自由选择非常适合他们的低延迟 RDMA 方案。  以下是目前同时支持 RoCE 和 iWARP RDMA 的 HPE 以太网适配器清单。Chart of All HPE Models and Part Numbers 借助 HPE ProLiant、Apollo、HPE Synergy 和 HPE Cloudline 服务器中启用了 RDMA 的适配器,Marvell 打造出了一系列 10Gb 或 25GbE 数据中心连接解决方案产品组合。  除了支持低延迟 RDMA 外,以上适配器还支持 NVMe。  这意味着以上适配器能够适应于运行 RoCE 或 iWARP 的以太网光纤中的 NVMe,同时也支持基于 TCP 的 NVMe(即没有 RDMA)。  这为当今的数据中心在面对未来的工作负荷时提供了充分的选择。

    组合式基础架构: 令人振奋的以太网交换机新前景

    作者:Marvell 公司资深架构师 George Hervey

    数据中心的网络格局正在发生巨变。   适应性更好、运行效率更高的组合式基础架构将取代过去灵活性不足且相互孤立的传统数据中心结构,快速获得显著增长,并走向普及。

    组合式基础架构采用一种现代化的软件定义方法来进行数据中心实施。 这意味着,通过使用 NMVe 和 NVMe-over-Fabric 协议,您将可以采用一个更通用的架构,而不必构建专门的存储区域网络 (SAN)。

    Whereas previously data centers had separate resources for each key task, composable infrastructure enables compute, storage and networking capacity to be pooled together, with each function being accessible via a single unified fabric.  This brings far greater operational efficiency levels, with better allocation of available resources and less risk of over provisioning --- critical as edge data centers are introduced to the network, offering solutions for different workload demands. 

    Composable infrastructure will be highly advantageous to the next wave of data center implementations though the increased degree of abstraction that comes along presents certain challenges --- these are mainly in terms of dealing with acute network congestion --- especially in relation to multiple host scenarios. Serious congestion issues can occur, for example, when there are several hosts attempting to retrieve data from a particular part of the storage resource simultaneously.  Such problems will be exacerbated in larger scale deployments, where there are several network layers that need to be considered and the degree of visibility is thus more restricted. 

    企业急需一款更具创新性的数据中心协调方法。 而这需要精简网络架构,以便顺利迁移至包含较少网络层的组合式基础架构,进而提高透明度,并减少拥堵。

    这种新方法将简化数据中心实施,无需过多投资购置昂贵的硬件,而且还可大大降低延迟和功耗。

    Further, the integration of advanced analytical mechanisms is certain to be of huge value here as well --- helping with more effective network management and facilitating network diagnostic activities.  Storage and compute resources will be better allocated to where there is the greatest need. Stranded capacity will no longer be a heavy financial burden. 

    利用大幅优化后的架构,数据中心将能够轻松迁移至组合式基础架构。  网络管理者将可以更好地了解流量层面发生的情况,并及时部署适当的响应措施。未来投资将更加有的放矢,提高系统利用率。

    NVMe/TCP - 简化是创新的关键

    By Nishant Lodha, Director of Product Marketing – Emerging Technologies, Marvell

    Whether it is the aesthetics of the iPhone or a work of art like Monet’s ‘Water Lillies’, simplicity is often a very attractive trait. I hear this resonate in everyday examples from my own life - with my boss at work, whose mantra is “make it simple”, and my wife of 15 years telling my teenage daughter “beauty lies in simplicity”. For the record, both of these statements generally fall upon deaf ears. 

    如今正推动数据存储发展的 Non-Volatile Memory over PCIe Express (NVMe) 技术,便是简单价值开始逐渐受到认可的又一领域。尤其是随着 NVMe-over-Fabrics (NVMe-oF) 拓扑的出现,该技术的部署将越来越多。这一简单又可信的以太网光纤,即传输控制协议 (TCP),现已成为经 NVMe Group 批准认可的 NVMe-oF 标准[1]。

    All the NVMe fabrics currently available图 1: 当前可用的所有 NVMe 光纤

    这里给大家提供一些背景信息,大体而言,NVMe 是借助高速接口(如 PCIe)访问以及专用于闪存实施的简化指令集,以高效利用基于闪存的固态硬盘 (SSD)。现在,按照定义,NVMe 限于单个服务器,这就带来了一项挑战,即很难横向扩展 NVMe 并从数据中心的任何元素进行访问。这便是 NVMe-oF 派上用处的地方。全闪存阵列 (AFA)、即闪存簇 (JBOF) 或网络化闪存簇 (FBOF) 和软件定义存储 (SDS) 架构皆能整合一个基于 NVMe-oF 连接的前端。由此一来,将大大提升服务器、客户端和应用访问外部存储资源的效率。

    A series of ‘fabrics’ have now emerged for scaling out NVMe. The first of these being Ethernet Remote Direct Memory Access (RDMA) - in both its RDMA over Converged Ethernet (RoCE) and Internet Wide-Area RDMA Protocol (iWARP) derivatives. It has been followed soon after by NVMe-over-Fiber Channel (FC-NVMe), and then ones based on FCoE, Infiniband and OmniPath. 

    But with so many fabric options already out there, why is it necessary to come up with another one? Do we really need NVMe-over-TCP (NVMe/TCP) too? Well RDMA (whether it is RoCE or iWARP) based NVMe fabrics are supposed to deliver the extremely low level latency that NVMe requires via a myriad of different technologies - like zero copy and kernel bypass - driven by specialized Network Interface Controller (NICs). However, there are several factors which hamper this, and these need to be taken into account.

    • 首先,大多数早期的光纤(如 RoCE/iWARP)并没有什么值得一提的现有存储网络安装基础(Fiber Channel 是一个明显例外)。 例如,目前在企业数据中心运行的 1200 万 10GbE+ NIC 端口中,只有不到 5% 具有 RDMA 功能(根据我的粗略估计)。
    • 非常流行的 RDMA 协议 (RoCE) 要求在无损网络上运行(而这则需要配备薪水要求更高的高技术网络工程师)。更令人沮丧的是,即便如此,该协议也容易发生拥堵问题。
    • 最后,可能也是富有说服力的一点,这两项 RDMA 协议(RoCE 和 iWARP)相互不兼容。

    Unlike any other NVMe fabric, the pervasiveness of TCP is huge - it is absolutely everywhere. TCP/IP is the fundamental foundation of the Internet, every single Ethernet NIC/network out there supports the TCP protocol. With TCP, availability and reliability are just not issues to that need to be worried about. Extending the scale of NVMe over a TCP fabric seems like the logical thing to do. 

    NVMe/TCP 非常快速(尤其是在使用 Marvell FastLinQ 10/25/50/100GbE NIC 的情况下 – 因为它们具有一个用于 NVMe/TCP 的内置充分卸载),可以充分利用现有的基础架构,让事务本身变得更加简单。这是所有技术人员期盼的美好前景,而且对于担忧预算的公司首席信息官来说也充满吸引力。

    从长远角度来看,简化再一次获胜!

    寻求网络聚合? HPE 推出新一代 Marvell FastLinQ CNA

    By Todd Owens, Field Marketing Director, Marvell

    将网络和存储 I/O 融合到单一网卡上可以减少所需的连接量,从而显着降低中小型数据中心的成本。 更少的适配器端口意味着更少的电缆、光学器件和交换机端口消耗,这些都能够减少数据中心的运行费用(OPEX)。 客户可以凭借部署融合网络适配器 (CNA),不仅可以提供网络连接,也为 iSCSI 和 FCoE 提供存储卸载。

    最近,HPE 已推出两款基于 Marvell® FastLinQ® 41000 系列技术的新型 CNA。 HPE StoreFabric CN1200R 10GBASE-T 融合网络适配器和 HPE StoreFabric CN1300R 10/25Gb 融合网络适配器都是 HPE CNA 组合中的新面世产品。 这些是一项支持远程直接内存访问 (RDMA) 技术(且同时支持存储卸载功能)的 HPE StoreFabric CNA。

    众所周知,需要存储设备的数据生成量正在不断增加。 最近,中端市场、分支机构和校园环境中的 iSCSI 连接存储设备的数量有所增加。iSCSI 非常适合这些环境,因为它易于部署、支持在标准以太网上运行,并且支持各种新型的 iSCSI 存储产品,如 Nimble 和 MSA 全闪存存储阵列 (AFA)。

    iSCSI 面临的一项挑战在于,使用软件启动器(此为存储连接的一般方法)时,处理存储流量所形成的服务器 CPU 负载。 为解决这一问题,存储管理员可以改用配有完整 iSCSI 协议硬件卸载的 CNA。 O将处理存储 I/O 的负担从 CPU 上卸载并转移至适配器。Benefits of Adapter Offloads 图 1: Benefits of Adapter Offloads 

    如图 1 所示,通过 Marvell 驱动测试可以看出,相较于配置软件启动器的以太网 NIC,在 FastLinQ 10/25GbE 适配器中使用 H/W 卸载可以将 CPU 使用率降低 50% 之多。 这表明 CPU 的负担得以缓解,因此您可以为各服务器添加更多虚拟机,并且还可能减少物理服务器的需求数量。 使用 Marvell 智能 I/O 适配器等就可以大幅度节约 TCO。

    而另一项挑战则是以太网连接的相关延迟问题。 如今,利用 RDMA 技术即可解决这一难题。iWARP, 通过融合以太网的 RDMA (RoCE) 以及通过以太网配置 RDMA 的 iSCSI (iSER) 均可绕过(bypass) O/S 用户空间中的软件内核,实现内存与适配器的直接访问。 这能加快事务执行的速度,并减少整体 I/O 延迟情况。 由此将获得更好的性能和更快的应用程序。

    新型 HPE StoreFabric CNA 现已成为 HPE ProLiant 和 Apollo 客户融合网络和 iSCSI 存储流量的理想设备。 HPE StoreFabric CN1300R 10/25GbE CNA 支持同时分配至网络和存储流量的海量宽带。 此外,此款适配器支持 通用 RDMA (支持 iWARP 和 RoCE)以及 iSER,因此在网络和存储流量上的延迟均显著低于标准网络适配器。

    HPE StoreFabric 1300R 还支持 Marvell SmartAN™, 技术,允许适配器在 10GbE 和 25GbE 网络间转变时进行自动配置。 这一点非常关键的原因在于,在 25GbE 速率下,可以根据使用电缆请求前向纠错 (FEC)。 执行两种不同类型的 FEC 可以增加复杂度。 如要消除所有的复杂性,SmartAN™ 将自动配置适配器以匹配 FEC、缆线和交换机设置,实现 10GbE 或 25GbE 自适应连接,且全程无需用户干预。

    如果预算是关键考虑因素,HPE StoreFabric CN1200R 将是优质选择。 支持 10GBASE-T 连接,此款适配器采用 RJ-45 连接与现有的 CAT6A 铜缆相连接。 这消除了对昂贵的 DAC 电缆或光收发器的需求。 StoreFabric CN1200R 还支持 RDMA 协议(iWARP、RoCE 和 iSER),降低整体延迟情况。

    但是为什么要实现融合呢? 这是权衡成本和性能作出的折衷办法。 如果我们计算并对比分别部署 LAN 和存储网络与融合网络的成本就能从中发现,融合 I/O 在极大程度上降低了基础设施的复杂程度,并能将购置成本减半。 另外,相较于管理两个网络,管理单个网络还能节约更多长期成本。Eight Server Network Infrastructure Comparison 图 2: Eight Server Network Infrastructure Comparison

    In this pricing scenario, we are looking at eight servers connecting to separate LAN and SAN environments versus connecting to a single converged environment as shown in figure 2.  Table 1: LAN/SAN versus Converged Infrastructure Price Comparison 

    融合环境的价格比分离式网络方式低 55%。 不足之处在于,从分离网络环境中的光纤通道 SAN 转移到融合 iSCSI 环境中所产生的潜在存储性能影响。 利用数据中心桥接、优先级流量控制以及 RoCE RDMA 实现无损以太网环境,从而优化 iSCSI 性能。 这样做的确非常大地增加了网络复杂程度,但将通过减少存储流量中断数从而提高 iSCSI 性能。

    这些新型适配器还有其它应用场景,如超融合基础设施 (HCI) 实施。 利用 HCI 中由软件定义的存储。 这表示服务器中的存储属于跨网络共享。 常见实施包括部署 Windows Storage Spaces Direct (S2D) 和 VMware vSAN 就绪节点。 HPE StoreFabric CN1200R BASE-T 和 CN1300R 10/25GbE CNA 经证明均可用于这些 HCI 实施。FastLinQ Technology Certified for Microsoft WSSD and VMware vSAN Ready Node 图 3: FastLinQ Technology Certified for Microsoft WSSD and VMware vSAN Ready Node 

    总之,HPE StoreFabric 团队推出的新型 CNA 实现了融合环境的高性能低成本连接。 SmartAN™ 技术支持 10Gb 和 25Gb 以太网宽带、iWARP、RoCE RDMA,以及自动协调 10GbE 和 25GbE 连接之间的变化,对于中小型服务器和存储网络而言,这些都是理想的 I/O 连接选项。  欢迎选择 Marvell FastLinQ Ethernet I/O 技术(此技术能够从源头为您考虑性能、购置成本、灵活性和可扩展性),以充分利用对服务器的投资。

    By Maen Suleiman, Senior Software Product Line Manager, Marvell and Gorka Garcia, Senior Lead Engineer, Marvell Semiconductor, Inc.

    Thanks to the respective merits of its ARMADA® and OCTEON TX® multi-core processor offerings, Marvell is in a prime position to address a broad spectrum of demanding applications situated at the edge of the network. These applications can serve a multitude of markets that include small business, industrial and enterprise, and will require special technologies like efficient packet processing, machine learning and connectivity to the cloud. As part of its collaboration with Amazon Web Services® (AWS), Marvell will be illustrating the capabilities of edge computing applications through an exciting new demo that will be shown to attendees at Arm TechCon - which is being held at the San Jose Convention Center, October 16th-18th. 

    此次演示模拟的是一个自动停车场的应用场景。以 ARMADA 处理器为基础的 Marvell MACCHIATObin® 社区开发板集成了 AWS Greengrass® 软件,可用作边缘计算节点。Marvell 边缘计算节点会接收放置在停车场入口和出口处两个摄像机的视频流。以 ARMADA 处理器为基础的计算节点会运行 AWS Greengrass 核心;执行两个 Lambda 函数来处理传入的视频流并通过识别牌照辨识进入停车场的车辆;然后检查进入停车场的车辆是否经过授权。

    第一 Lambda 函数将运行自动车牌识别 (OpenALPR) 软件以获取车牌号并将其与道闸 ID(入口/出口)一起传送到 AWS® 云端上运行的 Lambda 函数,该函数将存取 DynamoDB® 数据库。云端 Lambda 函数将负责读取 DynamoDB 白名单数据库并确定车牌是否属于授权汽车。该信息将被发送回网络边缘 MACCHIATObin 开发板上的第二 Lambda 函数,负责管理停车场容量和开关道闸。此 Lambda 函数会将边缘活动记录到 AWS Cloud Elasticsearch® 服务,该服务充当开源数据可视化引擎 Kibana® 的后端。Kibana 使远程操作人员能够直接访问有关停车场占用情况、入口道闸状态和出口道闸状态的信息。  此外,AWS Cognito 服务将对用户进行身份验证,确认访问 Kibana 的权限。AWS Cognito service     AWS Cloud Lambda function

    在 AWS Cloud Lambda 函数将判定(允许/拒绝)发送到 MACCHIATObin 开发板上运行的第二 Lambda 函数后,此 MACCHIATObin Lambda 函数将负责与道闸控制器通信,该控制器由 Marvell ESPRESSObin® 开发板组成,用于根据需要打开/关闭道闸。

    ESPRESSObin 开发板作为 AWS Greengrass IoT 设备运行,负责根据从 MACCHIATObin 开发板的第二 Lambda 函数收到的信息打开道闸。

    此次演示展示了在边缘使用 AWS Lambda 运行机器学习算法的功能,能使识别过程变得非常迅捷。凭借高性能、低功耗的 Marvell OCTEON TX 和 ARMADA 多核处理器,快速的识别过程得以实现。Marvell 基础架构处理器的功能具有涵盖一系列高端网络和安全应用的潜力,这些应用可以从 Arm® 生态系统的成熟度和在网络边缘的多核环境中运行机器学习的能力中受益。

    Those visiting the Arm Infrastructure Pavilion (Booth# 216) at Arm TechCon (San Jose Convention Center, October 16th-18th) will be able to see the Marvell Edge Computing demo powered by AWS Greengrass.

    IOPs 和延迟

    By Marvell PR Team

    That’s why system administrators try to understand its performance and plan accordingly.

    This can get quite complicated. Fortunately, storage performance can effectively be represented using two simple metrics: Input/Output operations per Second (IOPS) and Latency.

    Let’s understand what these key factors are and how to use them to optimize of storage performance. 

    What is IOPS?

    IOPS is a standard unit of measurement for the maximum number of reads and writes to a storage device for a given unit of time (e.g. seconds). IOPS represent the number of transactions that can be performed and not bytes of data. In order to calculate throughput, one would have to multiply the IOPS number by the block size used in the IO. IOPS standard unit IOPS is a neutral measure of performance and can be used in a benchmark where two systems are compared using same block sizes and read/write mix. 

    What is a Latency?

    Latency is the total time for completing a requested operation and the requestor receiving a response. Latency includes the time spent in all subsystems, and is a good indicator of congestion in the system. Latency IOPS is a neutral measure of performance and can be used in a benchmark where two systems are compared using same block sizes and read/write mix. 

    What is a Latency?

    Latency is the total time for completing a requested operation and the requestor receiving a response.

    Marvell 助力入门级无人机引入高清视频功能

    作者:Sree Durbha,Marvell 智能连接业务负责人

    Drone The consumer drone market has expanded greatly over the last few years, with almost 3 million units shipped during 2017. 这种上升趋势很可能继续持续。 据分析公司 Statista 预测,至 2020 年,商用无人机业务的市场规模将达 64 亿美元。另外,据 Global Market Insights 预测,全球无人机市场的整体规模到 2020 年将增长至 170 亿美元(其中消费类别占 90 亿美元)。 目前市场上已经有了非常多款型的无人机,而且新产品还在不断涌入,所以,新产品是否具有差异性对于其在市场上获得成功至关重要。

    众多涌入者中,新面世介入也非常让人喜出望外的产品之一便是 Tello,它所提供的功能与市场中的其他竞争产品截然不同。 Tello 由深圳创业公司 Ryze Tech 生产,该公司是世界上最大的无人机和无人飞行器 (UAV) 生产商 - 知名品牌 DJI 的子公司。 Tello 运行时间为 13 分钟,飞行距离可达 100 米,是一款非常具有操控性的紧凑型四旋翼无人机。 其重量只有 80 克,绝大多数青少年的手掌即可轻松掌握(尺寸仅为 98 x 92.5 x 41 毫米)。 Tello 具有娱乐和教育两大主要目标。 为实现此目标,基于智能手机应用的操控模式为每位用户(包括年轻人)提供了有趣的用户界面以与无人机进行互动。 而易于编程的可视化布局则满足了教育目标,允许用户使用软件包中包含的综合软件开发工具包 (SDK) 编写自己想要的代码。 What really distinguishes Tello from other drones, however, is the breadth of its imaging capabilities - and this is where engaging with Marvell has proven pivotal.

    Tello 自创的无人机设计,要求产品即使在以 8 米/秒的最大速度行驶时,也能够使用其 5 百万像素图像传感器将 720p MP4 格式直播视频实时传送到用户的智能手机或平板电脑。 这需要与各种型号智能手机和平板电脑广泛进行互操作性测试。 由于其尺寸小巧,电池的续航能力成为关键要素,基于此,超低功耗的 Wi-Fi® 必不可少。 实现所需一切要求的基础就是:需要强大的无线连接以确保无人机在任何时间都能保持信号传输。 最后,一如既往,需要在产品物料成本有限的情况下实现卓越的 Wi-Fi 技术。

    Initial discussions between technical teams at Ryze and Marvell revealed a perfect match between the features offered on the Marvell® 1x1 802.11n single-band Wi-Fi system-on-chip (SoC) and the Wi-Fi requirements for the Tello drone project. 该芯片在市场上得到广泛采用,并已成为各种客户应用中出色的解决方案,包括 IP 摄像头、移动路由器、IoT 网关等。 睿炽公司最终选择此芯片组,是因为 Marvell 产品在空中无线传输高清视频的同时具备可靠性,且能在提供超低功耗操作的同时表现出超量程的卓越 RF 性能,并且其价格非常具有竞争力。

    Marvell 的 Wi-Fi SoC 是一款高度集成的单频 (2.4GHz) IC,可在单一空间流 (1 SS) 配置下提供 IEEE® 802.11b/g/n 操作。 它集成了功率放大器 (PA)、低噪音放大器 (LNA) 和发射/接收开关功能。 服务质量 (QoS) 通过 802.11e 标准实施得到保证。 Wi-Fi SoC 符合 802.11i 安全协议,并且内置有线等效加密 (WEP) 算法,可对传输数据进行 128 位加密,从而保护数据不被第三方拦截。 Marvell 强大的 Wi-Fi 软件支持所有此类硬件功能,该软件包含与硬件级功能相吻合的占用空间小且功能齐全的 Wi-Fi 固件。 基础结构模式操作等特定功能的开发旨在实现 Tello 所需要的各项功能。

    Marvell 业界排名靠前的 Wi-Fi 技术为 Tello 带来了令人兴奋的用户体验,而如此精巧的设计以往只能在昂贵的专业级设备中出现。 要将这种专业质量体验引入到入门级无人机中,意味着需要克服动力、性能和成本等重重阻碍。 随着 Wi-Fi 产业升级至 802.11ax 时代,Marvell 相信将率先在市场上推出支持先进技术的产品,例如上行链路 OFDMA。

    为什么 802.11ax 对于联网汽车而言“必不可少”?

    By Avinash Ghirnikar

    设想一下这样的场景,您正驾驶着全新的联网汽车穿梭在繁忙的城市道路中,而这辆互联汽车在行驶过程中不断“学习”,变得更加智能、安全和可靠。 这样的汽车会不断收集和生成各种数据,并不时寻找机会将这些数据上传至云端。 随着越来越多具备先进无线联网功能的车辆上路,这种激动人心的未来将变成平凡的日常生活。 然而,每辆车都有可能需要与其附近出现的数百辆汽车共享网络。这种使用情况有可能依赖于 LTE/5G 蜂窝技术,其成本与所采用的该类“授权管道”紧密相关,而此管道的费用非常昂贵。 在这种情况下,新款 Wi-Fi® 标准 802.11ax,也称为 线 (HEW),即会成为汽车电子行业的救命稻草。 配备众多传感器的汽车在未来将要产生的泽字节数据,都将需要上传至云端和数据中心,实现下一代的机器学习,从而使车辆驾驶在未来愈加安全和可预测。 当然,上传这些数据需要安全可靠地完成。802.11ax connected cars The car - as an 802.11ax station (STA) - will also be to able upload data to an 802.11ax access point (AP) in the most challenging of wireless environments while sharing the network with other clients. 802.11ax 系统将能够通过诸如 MU-MIMO 和 OFDMA (允许空间、频率和时间重用)等新技术来实现上述功能,这些技术是 802.11ax 新标准的一部分创新内容。 今天,STA 领域内互相竞争,其视线并未聚焦于有效分享网络以及不得不面对的等待连接中可怕的“死亡循环”。 这是因为当今的无线标准由于持续的竞争,经常会陷入“不成功则成仁”的二进制运行模式。 而当与其他如 802.11ai(尤其是快速初始链路建立 (FILS))等新兴标准相结合时,这种新型汽车通过 Wi-Fi 将数据上传至云端将变为现实,即使是在汽车移动过程中以及可能在 AP 间不断跳转的环境下也是如此。这种“引擎盖下”的上传使用情况,从基础设施角度来看,因 802.11ax 标准而得到大幅增强,同时将软件和固件下载到联网汽车中的情况也可能因同样的标准而发生转变。 众所周知,各型号车辆中处理器和电子控制单元 (ECU) 的数量预计将大幅增加。 这反过来又意味着汽车中的软件/固件内容同样将以指数速度增长, 这将需要周期性的空中固件 (FOTA) 升级,因此拥有可靠、强劲的机制以对此提供支持,对汽车制造商而言至关重要,将有可能为其在服务成本等方面节省数百万美元。  这就是当今时代创新和技术变革的节奏,这种变革机制可能在汽车脱离生产线的下一秒就发挥作用。以汽车厂商工厂外的停车场为例,其中或许有数百辆全新汽车需要更新一些软件。  对于这种情况,802.11ax 亦大有帮助,可以更加有效和可靠的进行批量更新。 此一优势将更进一步在每辆车的整个使用寿命中发挥作用,因为没人知道这些车辆将遇到何种类型的无线网络连接环境。 这些有可能是非常具有挑战的环境,例如车库、行车道,甚至有可能是多层停车场。 802.11ax 所提供的的调制增强功能,与 MU-MIMO 和 OFDMA 特性相配合,将确保非常高效可靠的 Wi-Fi 管道对此关键功能随时可用。 考虑到车辆在近十年的时间内将需要经常上路,在初期即为车辆加载此功能将具有很大优势,并将节省大量成本。 再次重申,随附的低能耗 Wake on Bluetooth® 和远程低能耗蓝牙等功能,也将发挥关键作用,从整体端到端系统立场确保实现此使用情况。这两种基础设施类型使用情况将为联网汽车带来非常高的附加值,并将证实装备 802.11ax 的必要性,尤其是从汽车制造商的视角而言。 甚至消费者也可以在他们的汽车仪表盘上看到自己获取的巨大利益,信息娱乐系统中的移动 AP 将可以无缝连接他们的最新款智能手机设备(这些设备将在 2019 时间段内实现自带支持 802.11ax)。 有了 802.11ax 额外 30-40% 的吞吐量提升(以及此标准所具备的对以往此类使用情况所应用 Wi-Fi 标准的后向兼容协同共存特性),如无线 Apple CarPlay®、无线 Android Auto™ 投射、后座娱乐、无线摄像头等使用情况都将是小菜一碟。  同在家中一样,车载 Wi-Fi 端点的数量也在不断激增。 802.11ax 标准是一款设计完善的通路,支持不断增长的端点数量,同时能提供最佳用户体验。802.11ax 的 Release 1 版本(又名Wave 1)正在准备通过 Wi-Fi 联盟于2019年下半年发布, Products are already being sampled by silicon vendors - both on the AP and STA/mobile AP side - and interoperability testing is well underway. 对于原始设备制造商及其一级供应商的所有无线系统设计人员来说,802.11ax Wi-Fi 标准应该是一个他们非常期盼的目标,尤其是针对 2020 年及以后的任何产品发布,  是时候准备迎接 802.11ax 基础设施的到来,为此开始前瞻性开发了。 智能手机/家庭/企业及车载无线技术分属不同级别的时代已经一去不复返了。 消费者现在想要他们的车辆成为家庭/工作环境的延伸,并需要这些居住空间协同运作。 802.11ax 注定要成为实现这一愿景的关键技术支柱之一。自 2011 年车载 Wi-Fi/蓝牙组合设备出现以来,Marvell 一直是汽车电子市场此类设备设计方面的先驱。 随着近十年前实质性开发的启动,通过与 OEM、第 1 级和第 2 级的紧密合作,Marvell 汽车电子无线产品系列经过精心打磨,已经满足了超过五代产品的关键使用情况需求。 支持上述各种应用所需的所有技术都已被集成到 Marvell 第五代芯片中。 Coupled with Marvell’s offering for enterprise class, high-performance APs, Marvell remains committed to providing the automobile industry and car buyers with the best wireless connectivity experience -- encompassing use cases inside and outside of the car today, and well into the future.

    可用于 HPE Cloudline 服务器的 Cavium FastLinQ 以太网适配器

    By Todd Owens, Field Marketing Director, Marvell

    Are you considering deploying HPE Cloudline servers in your hyper-scale environment? If you are, be aware that HPE now offers select Cavium ™ FastLinQ® 10GbE and 10/25GbE Adapters as options for HPE Cloudline CL2100, CL2200 and CL3150 Gen 10 Servers. The adapters supported on the HPE Cloudline servers are shown in table 1 below.

    Faster processors, increase in scale, high performance NVMe and SSD storage and the need for better performance and lower latency have started to shift some of the performance bottlenecks from servers and storage to the network itself.

    • Lower CPU utilization to free up resources for applications or more VM scalability
    • Accelerate processing of small-packet I/O with DPDK
    • Save time by automating adapter connectivity between 10GbE and 25GbE
    • Reduced latency through direct memory access for I/O transactions to increase performance
    • Network isolation and QoS at the VM level to improve VM application performance
    • Reduce TCO with heterogeneous management

    Cavium FastLinQ Adapter and HPE Cloudline Gen10 Server

    Advanced Features in Cavium FastLinQ Adapters for HPE Cloudline

    * Source; Demartek findings 
    Table 2: Advanced Features in Cavium FastLinQ Adapters for HPE Cloudline

    Network Partitioning (NPAR) virtualizes the physical port into eight virtual functions on the PCIe bus. This makes a dual port adapter appear to the host O/S as if it were eight individual NICs. Furthermore, the bandwidth of each virtual function can be fine-tuned in increments of 500Mbps, providing full Quality of Service on each connection. SR-IOV is an additional virtualization offload these adapters support that moves management of VM to VM traffic from the host hypervisor to the adapter. This frees up CPU resources and reduces VM to VM latency. 

    Remote Direct Memory Access (RDMA) is an offload that routes I/O traffic directly from the adapter to the host memory. This bypasses the O/S kernel and can improve performance by reducing latency. The Cavium adapters support what is called Universal RDMA, which is the ability to support both RoCEv2 and iWARP protocols concurrently. This provides network administrators more flexibility and choice for low latency solutions built with HPE Cloudline servers. 

    SmartAN is a Cavium technology available on the 10/25GbE adapters that addresses issues related to bandwidth matching and the need for Forward Error Correction (FEC) when switching between 10Gbe and 25GbE connections. For 25GbE connections, either Reed Solomon FEC (RS-FEC) or Fire Code FEC (FC-FEC) is required to correct bit errors that occur at higher bandwidths. For the details behind SmartAN technology you can refer to the Marvell technology brief here

     For simplified management, Cavium provides a suite of utilities that allow for configuration and monitoring of the adapters that work across all the popular O/S environments including Microsoft Windows Server, VMware and Linux. Cavium’s unified management suite includes QCC GUI, CLI and v-Center plugins, as well as PowerShell Cmdlets for scripting configuration commands across multiple servers. Cavum’s unified management utilities can be downloaded from www.cavium.com .

    By Todd Owens, Field Marketing Director, Marvell

    VMware vSAN ReadyNode Recipes Can Use Substitutions When you are baking a cake, at times you substitute in different ingredients to make the result better. The same can be done with VMware vSAN ReadyNode configurations or recipes. Some changes to the documented configurations can make the end solution much more flexible and scalable. In this VMware BLOG, the author outlines that server elements in the bom can change including:
    • CPU
    • 存储器
    • Caching Tier
    • Capacity Tier
    • NIC
    • Boot Device
    However, changes can only be made with devices that are certified as supported by VMware. The list of certified I/O devices can be found on VMware vSAN Compatibility Guide and the full portfolio of NICs, FlexFabric Adapters and Converged Network Adapters form HPE and Cavium are supported. If we zero in on the HPE recipes for vSAN ReadyNode configurations, here are the substitutions you can make for I/O adapters. Ok, so we know what substitutions we can make in these vSAN storage solutions. What are the benefits to the customer for making this change? There are several benefits to the HPE/Cavium technology compared to the other adapter offerings.
    • HPE 520/620 Series adapters support Universal RDMA – the ability to support both RoCE and IWARP RDMA protocols with the same adapter.
      • NPAR (Network Partitioning) allows for virtualization of the physical adapter port. SR-IOV Offloadmove management of the VM network from the Hypervisor (CPU) to the Adapter. With HPE/Cavium adapters, these two technologies can work together to optimize the connectivity for virtual server environments and offload the Hypervisor (and thus CPU) from managing VM traffic, while providing full Quality of Service at the same time.
    • Offloads in general – In addition to RDMA, Storage and SR-IOV Offloads mentioned above, HPE/Cavium Ethernet adapters also support TCP/IP Stateless Offloads and DPDK small packet acceleration offloads as well. Each of these offloads moves work from the CPU to the adapter, reducing the CPU utilization associated with I/O activity. As mentioned in my previous blog, because these offloads bypass tasks in the O/S Kernel, they also mitigate any performance issues associated with Spectre/Meltdown vulnerability fixes on X86 systems.
    • Adapter Management integration with vCenter – All HPE/Cavium Ethernet adapters are managed by Cavium’s QCC utility which can be fully integrated into VMware v-Center. This provides a much simpler approach to I/O management in vSAN configurations.
    In summary, if you are looking to deploy vSAN ReadyNode, you might want to fit in a substitution or two on the I/O front to take advantage of all the intelligent capabilities available in Ethernet I/O adapters from HPE/Cavium.

    理解当今的网络遥测需求

    作者:Tal Mizrahi,Marvell 特征定义架构师

    最近几年,网络实施的方式发生根本变化,随着数据需求的增长,类型更广泛的功能和运行性能水平的提高已经成为一种必要条件。 与之相伴的是另一种更大的需求,即针对该项性能标准的实时准确测量方式,以及深度分析,以便在任何潜在问题发展升级之前,查找并后续进行解决。

    当今的数据网络发展速度不断加快且复杂性不断攀升,意味着对这类活动的监控进程难度越来越大。 结果导致只能强制执行更加繁琐且本质灵活的遥测机制,尤其是对于数据中心和企业网络。

    当人们试图提取遥测资料时,发现有范围广大的多种不同选项,包括被动监控、主动测量和混合方法。 最普遍的一种做法是骑肩跟随遥测信息进入正在通过网络的数据包。 这种策略应用于原处 OAM (IOAM) 和带内网络遥测 (INT),以及替代进行的性能测量 (AM-PM) 背景之下。

    Marvell 的方法是提供多样化且通用性高的工具组,可以通过它执行各种各样的遥测方法,而非局限于一种特定的测量协议。 欲了解此主题的更多信息,包括长久以来普遍所用的被动和主动测量协议,以及崭新的混合型遥测方法,请观看以下视频并下载 Marvell 白皮书。

    Connecting Shared Storage – iSCSI or Fibre Channel

    By Todd Owens, Field Marketing Director, Marvell

    One of the questions we get quite often is which protocol is best for connecting servers to shared storage?

    What customers need to do is look at the reality of what they need from a shared storage environment and make a decision based on cost, performance and manageability.

      list of Hewlett Packard Enterprise (HPE) component pricesNotes: 1. Optical transceiver needed at both adapter and switch ports for 10GbE networks. Thus cost/port is two times the transceiver cost 2. FC switch pricing includes full featured management software and licenses 3. FC Host Bus Adapters (HBAs) ship with transceivers, thus only one additional transceiver is needed for the switch port 

    So if we do the math, the cost per port looks like this: 

    10GbE iSCSI with SFP+ Optics = $437+$2,734+$300 = $3,471 

    10GbE iSCSI with 3 meter Direct Attach Cable (DAC) =$437+$269+300 = $1,006 

    16GFC with SFP+ Optics = $773 + $405 + $1,400 = $2,578 

    Note, in my example, I chose 3 meter cable length, but even if you choose shorter or longer cables (HPE supports from 0.65 to 7 meter cable lengths), this is still the lowest cost connection option. Surprisingly, the cost of the 10GbE optics makes the iSCSI solution with optical connections the most expensive configuration.

    It really comes down to distance and the number of connections required. The DAC cables can only span up to 7 meters or so. That means customers have only limited reach within or across racks. If customers have multiple racks or distance requirements of more than 7 meters, FC becomes the more attractive option, from a cost perspective.

    • Latency is an order of magnitude lower for FC compared to iSCSI. Latency of Brocade Gen 5 (16Gb) FC switching (using cut-through switch architecture) is in the 700 nanoseconds range and for 10GbE it is in the range of 5 to 50 microseconds. The impact of latency gets compounded with iSCSI should the user implement 10GBASE-T connections in the iSCSI adapters. This adds another significant hit to the latency equation for iSCSI.

    图 1: Cavium’s iSCSI Hardware Offload IOPS Performance  

    图 2:

    Keep in mind, Ethernet network management hasn’t really changed much. Network administrators create virtual LANs (vLANs) to separate network traffic and reduce congestion. These network administrators have a variety of tools and processes that allow them to monitor network traffic, run diagnostics and make changes on the fly when congestion starts to impact application performance.

    On the FC side, companies like Cavium and HPE have made significant improvements on the software side of things to simplify SAN deployment, orchestration and management. Technologies like fabric-assigned port worldwide name (FA-WWN) from Cavium and Brocade enable the SAN administrator to configure the SAN without having HBAs available and allow a failed server to be replaced without having to reconfigure the SAN fabric. Cavium and Brocade have also teamed up to improve the FC SAN diagnostics capability with Gen 5 (16Gb) Fibre Channel fabrics by implementing features such as Brocade ClearLink™ diagnostics, Fibre Chanel Ping (FC ping) and Fibre Channel traceroute (FC traceroute), link cable beacon (LCB) technology and more. HPE’s Smart SAN for HPE 3PAR provides the storage administrator the ability to zone the fabric and map the servers and LUNs to an HPE 3PAR StoreServ array from the HPE 3PAR StoreServ management console. 

    In many enterprise environments, there are typically dozens of network administrators. In those same environments, there may be less than a handful of “SAN” administrators. Yes, there are lots of LAN connected devices that need to be managed and monitored, but so few for SAN connected devices.

    Well, it depends. If application performance is the biggest criteria, it’s hard to beat the combination of bandwidth, IOPS and latency of the 16GFC SAN. If compatibility and commonality with existing infrastructures is a critical requirement, 10GbE iSCSI is a good option (assuming the 10GbE infrastructure exists in the first place). If security is a key concern, FC is the best choice. When is the last time you heard of a FC network being hacked into?

    如果您还没有使用智能 I/O 适配器,您值得拥有!

    By Todd Owens, Field Marketing Director, Marvell

    Like a kid in a candy store, choose I/O wisely. 

    But with so many choices, the decision was often confusing. With time running out, you’d usually just grab the name-brand candy you were familiar with. But what were you missing out on?

    There are lots of choices and it takes time to understand all the differences. As a result, system architects in many cases just fall back to the legacy name-brand adapter they have become familiar with. Is this the best option for their client though? Not always.

    These adapters utilize a variety of offload technology and other capabilities to take on tasks associated with I/O processing that are typically done in software by the CPU when using a basic “standard” Ethernet adapter. Intelligent offloads include things like SR-IOV, RDMA, iSCSI, FCoE or DPDK. Each of these offloads the work to the adapter and, in many cases, bypasses the O/S kernel, speeding up I/O transactions and increasing performance.

    Another reason is to mitigate performance impact to the Spectre and Meltdown fixes required now for X86 server processors. The side channel vulnerability known as Spectre and Meltdown in X86 processors required kernel patches from the CPU vendor. These patches can have a significantly reduce CPU performance. For example, Red Hat reported the impact could be as much as a 19% performance degradation. That’s a big performance hit.

    offloads reduce impacts of Meltdown patches

    Some intelligent I/O adapters have port virtualization capabilities. Cavium Fibre Channel HBAs implement N-port ID Virtualization, or NPIV, to allow a single Fibre Channel port appear as multiple virtual Fibre Channel adapters to the hypervisor. For Cavium FastLinQ Ethernet Adapters, Network Partitioning, or NPAR, is utilized to provide similar capability for Ethernet connections. Up to eight independent connections can be presented to the host O/S making a single dual-port adapter look like 16 NICs to the operating system. Each virtual connection can be set to specific bandwidth and priority settings, providing full quality of service per connection.

    At HPE, there are more than fifty 10Gb-100GbE Ethernet adapters to choose from across the HPE ProLiant, Apollo, BladeSystem and HPE Synergy server portfolios. That’s a lot of documentation to read and compare. Cavium is proud to be a supplier of eighteen of these Ethernet adapters, and we’ve created a handy quick reference guide to highlight which of these offloads and virtualization features are supported on which adapters. View the complete Cavium HPE Ethernet Adapter Quick Reference guide here.

    For Fibre Channel HBAs, there are fewer choices (only nineteen), but we make a quick reference document available for our HBA offerings at HPE as well. You can view the Fibre Channel HBA Quick Reference here.

    崭新进展: 全新的 MACCHIATObin 社区开发板能够满足更大范围的开发者需求

    作者:Maen Suleiman,Marvell 软件产品线高级经理

    继去年春天成功发布 MACCHIATObin® 开发平台之后,Marvell 和有合作的技术伙伴 SolidRun 现在又宣布该硬件产品的崭新进展。 通过综合分析客户的反馈意见,两家公司对原始概念进行了一系列改进,使得这些 mini-ITX 板更加优化,以满足工程师的要求。

    Marvell 和 SolidRun 现在宣布推出两款全新的 MACCHIATObin 产品,这些将取代以前的版本。 这些新产品分别是 MACCHIATObin Single Shot 和 MACCHIATObin Double Shot

    与之前一样,这两款 mini-ITX 格式的网络社区板都集成 Marvell ARMADA®8040 系统单晶片 (SoC),具有强大的处理能力,并始终坚持原有的目标,即为市场提供更高性能同时兼具合适价格的基于 ARM 的开发资源。 However, now engineers have a choice in terms of how much supporting functionality comes with it - thus making the platform even more attractive and helping to reach a much wider audience. MACCHIATObin Single Shot(左)和 MACCHIATObin Double Shot(右) 

    图 1:MACCHIATObin Single Shot(左)和 MACCHIATObin Double Shot(右)

    精简版本的 MACCHIATObin Single Shot 是一个入门级板,可适用于预算有限的工程师。 这个版本比初始板价格低很多,只有 199 美元。 它配备有两个 10G SFP +连接器,去除了两个 10G 铜接头的选项,也没有之前版本标配的 DDR4 DIMM,但仍具备1.6GHz 的高处理速度。

    这些以 MACCHIATObin Double Shot 的更高性能作为补充。 改进的设计依托 64 位四核 Arm Cortex-A72 处理器内核,充分释放了 ARMADA 8040 2GHz 的处理能力。 MACCHIATObin Double Shot 包含有 4GB 的 DDR4 DIMM, At only $399 it represents great value for money - costing only slightly more than the original, but with extra features and stronger operational capabilities being delivered. It comes with additional accessories that are not in the Single Shot package - including a power cable and a microUSB-to-USB cable. 

    Single Shot 和 Double Shot 版本都采用散热器和风扇散热机制,以确保通过更有效的散热管理保持产品更高的可靠性。 风扇的气流速度可达每分钟 6.7 立方英尺 (CFM),并且保持较低噪声。 为了更好地利用可用空间,在原有设计基础上进行了一些布局改变,这样也可让板使用起来更加方便。 例如,改变了 SD 卡插槽的位置,使其更易于使用,同样 SATA 连接器的位置也比之前更加合理,能够更容易地连接多条线缆。 Micro-USB 插座也进行了重新设置,以方便工程师使用。

    控制台 (Console) UART(与 FTDI USB 至 UART 接口 IC 并行工作)添加了一个 3 针 UART 插头, 也就是说,开发人员现在可以使用额外的连接选项,使 MACCHIATObin 社区板更适合于远程部署,或用于连接没有 USB 端口的传统设备。 DIP 开关已经被跳线 (jumper) 所取代,这使这两款板能够实现更多的功能。 JTAG 连接器并没有默认地组装在一起,PCI Express (PCIe) x4 插槽已被一个开放的 PCIx4 插槽所取代,因此可以连接图形处理器卡等更多种不同的板选件(如 x8、x16 以及 x4 PCIe)。 而且,通用输入/输出 (GPIO) 控制的 LED 发射器已经取代原来固定的 LED 发射器,从而能够显示运行情况。

    事实上,这些单元与初始板中的单元形状相同,可以完全替代之前 MACCHIATObin 板的相关功能。 因此,已经在使用 MACCHIATObin 板的设计可升级到更高性能的 MACCHIATObin Double Shot 版本,或者相反缩减到 MACCHIATObin Single Shot 版本,以降低相关的成本。

    本次 MACCHIATObin Double Shot 和 Single Shot 的发布表明,Marvell 团队一直在倾听客户的意见和反馈,并迅速响应他们的需求。 通过从初始 MACCHIATObin 版本吸取经验,我们已经做出重大改进,并开发出两款各具特色的产品。 一种是要满足那些预算紧张的工程师的需求,而以前的版本不可能做到这一点。另一种是要帮助工程师的设计达到更高的性能水平。

    全球数据的存储

    By Marvell PR Team

    在当下以数据为中心的世界,数据存储是发展的基石,但未来的数据将如何存储却是一个广泛争论的问题。 显而易见,数据增长仍将保持大幅上升态势。 IDC 公司编写的一份题为“数据时代 2025”的报告指出,全世界生成的数据量将以接近指数级的速度增长。 到 2025 年,数据量预期将会超过 163 Zb(几乎是当今数据量的 8 倍,接近 2010 年数据量的 100 倍)。 随着云服务的使用量增加、物联网 (IoT) 节点的广泛部署,虚拟现实和增强现实应用、自动驾驶汽车、机器学习和“大数据”的盛行,都将在未来新的数据驱动时代发挥重要作用。

    展望未来,智能城市的建设需要部署非常精密的基础设施,以达到减少交通拥堵、提高公共设施效率、优化环境等等种类繁杂的目的,从而导致数据量进一步攀升。 未来的很大一部分数据需要满足实时访问。 这种需求将对我们采用的技术产生影响,也会影响数据在网络中的存储位置。 另外,还必须考虑到一些重要的安全因素。

    因此,为了能够控制开销,尽可能提高运营效率,数据中心和商业企业将尝试采用分层存储方法,使用非常合适的存储介质,以降低相关成本。 存储介质的选择将依据数据访问的频率及可接受的延迟程度而定。 This will require the use of numerous different technologies to make it fully economically viable - with cost and performance being important factors. 

    当前市面上有众多不同的存储介质。 有些存储介质已经非常成熟,有些则仍然处于新兴阶段。 在某些应用中,硬盘驱动器 (HDD) 正在被固态硬盘 (SSD) 取代,而在 SSD 领域,随着技术从 SATA 向 NVMe 的迁移,NVMe 正在促使 SSD 技术充分发挥自身性能潜力。 HDD 的容量持续大幅提高,整体性价比的提升也增加了设备的吸引力。 云计算保证了庞大的数据存储需求,这意味着 HDD 在这个领域具有强劲的发展动力。

    未来将出现其他形式的存储器,它们将帮助我们应对日益增长的存储需求所带来的挑战。 其中包括更高容量的 3D 堆栈闪存,也包括全新的技术,例如相变存储器,它的写入速度很快,使用寿命也更长。 随着基于光纤的 NVMe (NVMf) 接口的问世,高带宽、超低延迟、非常高的可扩展性的 SSD 数据存储迎来了广阔的前景。

    Marvell 很早就认识到数据存储的重要性将日益提高,并一直将这个领域作为发展重点,成为了业内 HDD 控制器消费级固态硬盘控制器排名靠前的供应商。

    在产品发布之后仅 18 个月,采用 NANDEdge™ 纠错技术的 Marvell 88SS1074 SATA SSD 控制器的出货量就突破了 5000 万件。 凭借屡获殊荣的 88NV11xx 系列小尺寸 DRAM-less SSD 控制器(基于 28nm CMOS 半导体工艺),Marvell 为市场提供了优化的高性能 NVMe 存储控制器解决方案,可在紧凑型简化手持式计算设备上采用,例如平板电脑和超级本。 这些控制器能够支持 1600Mb/s 的读取速度,而且功耗非常低,有利于节省电池电量。 Marvell 提供 88SS1092 NVMe SSD 控制器等解决方案,针对新计算模式设计,让数据中心能够共享存储数据,从而非常大程度地降低成本和提高性能效率。

    数据超乎想象的增长意味着需要更多的存储。 新兴应用和创新技术将促使我们采用全新方式来提高存储容量、缩短延迟和确保安全性。 Marvell 为行业提供一系列技术以满足数据存储需求,可以满足 SSD 或 HDD 实施要求,且配备所有配套接口类型,从 SAS 和 SATA 一直到 PCIe 和 NMVe。Marvell storing data 欲了解有关 Marvell 产品如何存储全球数据的更多信息,请访问 www.marvell.com

    以太网为车载网络带来根本性变革

    By By Christopher Mash, Senior Director of Automotive Applications & Architecture, Marvell

    目前汽车中采用的车载网络是基于几种不同数据网络协议的组合,其中一些已经使用了几十年。 第一种叫作控制器局域网 (CAN),主要负责动力总成和其他相关功能;第二种是本地互联网络 (LIN),主要用于对时间不敏感(如气候控制、环境照明、座椅调整等)的乘客和驾驶员舒适性用途;第三种是针对信息娱乐系统开发的面向媒体的系统传输 (MOST);第四种是用于防抱死制动 (ABS)、电子助力转向 (EPS) 和车辆稳定功能的 FlexRay™。

    由于采用了不同的协议,需要使用网关在网络设施中传输数据, 由此产生的复杂性也增加了汽车厂商的制造成本, 每个网络所需的布线也增加了车辆的重量,进而会影响车辆的燃油经济性。 对于一辆汽车而言,布线的重量在整车中的占比仅次于发动机和底盘之后,名列第三;同样在成本方面,布线成本占总成本比例,也是第三位。 此外,这些网关也存在延迟问题,势必会影响到需要快速响应的安全关键型应用。

    另一方面,汽车中的电子控制单元 (ECU) 数量在不断增加,目前豪华车型通常拥有 150 甚至更多个 ECU,甚至标准车型也拥有近 80~90 个 ECU。 与此同时,随着人们不断追逐更高级的汽车自动驾驶性能,数据密集型应用也在不断出现,以支持高级驾驶员辅助系统 (ADAS) 的实施。 所有这些都导致数据速率和整体带宽的显著提高,同时伴随高清摄像头和激光雷达技术的部署使用。

    因此,对于目前车载网络的改进从整体技术来讲,需要的是一个根本性的改变。首先是所使用的拓扑结构,其次是它所依赖的底层技术。

    目前,汽车内部的网络基础设施是基于域的架构。 There are different domains for each key function - one for body control, one for infotainment, one for telematics, one for powertrain, and so on. 一般这些域会使用不同类型相混合的网络协议(例如遵守 CAN、LIN 和其他相关协议)。

    随着网络复杂性的不断提高,汽车工程师越来越清楚地认识到,这种不同的域使用不同协议的方法效率越来越低。 因此,在未来几年中,将需要从目前基于域的体系架构转向区域 (zonal) 架构。

    区域架构实施方案可以使来自不同传统领域的数据,依据车辆中 ECU 的位置(区域)连接到同一个 ECU。 This arrangement will greatly reduce the wire harnessing required, thereby lowering weight and cost - which in turn will translate into better fuel efficiency. 以太网技术将成为中坚力量,推动车辆向基于区域的车载网络不断发展。

    以太网技术除了能够支持高数据速率之外,还同时支持广受认可的 OSI 通信模型。 以太网作为一种稳定、历史悠久、且广为人知的技术,已经在数据通信和工业自动化领域得到广泛应用。 与其他车载网络协议不同,以太网明确定义了面向更高速度等级的发展路线图,而 CAN、LIN 等协议却已经是某些应用发展的瓶颈,而且也没有明确的升级路径来缓解问题。

    展望未来,以太网技术将成为汽车所有数据传输的基础,通过提供一个共同的协议栈,减少不同协议之间对于网关的需求(以及硬件和相关的软件成本)。 结果将是整个车辆采用单一的同构网络,其中所有的协议和数据格式都是一致的。 这意味着,车载网络将可以扩展,从而实现一些要求更高速度(例如 10G)和更低延迟的功能,同时兼顾满足低速功能的需求。 Ethernet PHYs will be selected according to the particular application and bandwidth demands - whether it is a 1Gbps device for transporting imaging sensing data, or one for 10Mbps operation, as required for the new class of low data rate sensors that will be used in autonomous driving. 

    区域架构中的每个以太网交换机将能够为所有不同的域中的活动传送数据, 所有不同的数据域都将连接到本地交换机,再通过以太网骨干网聚合数据,从而更有效地使用已有的资源,以相同的核心协议,在需要时支持不同的速度。 这个同构网络将在车内提供“任何地点的任何数据”,还可以通过整合来自网络中不同域的数据来支持新的应用。

    目前,在基于以太网的车载网络和车辆区域架构的发展方面,Marvell 处于佼佼者地位。2017年夏季,Marvell 推出了面向汽车市场并符合 AEC-Q100 标准的 88Q5050 安全千兆以太网交换机。 该设备不仅能够处理与标准以太网实施密切相关的 OSI Layers 1-2(物理层和数据层)功能,还具有位于 OSI Layers 3,4 及以上(网络层、传输层和更高层)的深度包检测 (DPI) 等其他功能。 这些与可信引导 (Trusted Boot) 功能相结合,可为汽车网络架构师提供对于确保网络安全至关重要的功能。Automotive network architects with key features

    全球数据的传输

    作者:Marvell 公关团队

    有线和无线连接传输数据的方式正在发生重大转变, 而导致这些变化的原因来自于不同行业的多个层面。

    在汽车领域,随着新特性和新功能的引入,基于 CAN 和 LIN 的传统通信技术已经不足以满足需求。 我们必须部署更先进的车载网络,能够支持千兆位级的数据速率,这样才能处理由高清摄像头、更精密的信息娱乐系统、汽车雷达和 LiDAR 生成的大量数据。 With CAN, LIN and other automotive networking technologies not offering viable upgrade paths, it is clear that Ethernet will be the basis of future in-vehicle network infrastructure - offering the headroom needed as automobile design progresses towards the long term goal of fully autonomous vehicles. Marvell 在这场博弈中已经占据了领先位置,公司发布了业界首款安全车载千兆以太网交换机,提供当今汽车高数据负载设计所需的速度,同时还确保安全运行,减少黑客攻击或拒绝服务 (DoS) 攻击的威胁。

    随着工业 4.0 的到来,在现代工厂和加工厂环境中,我们将通过使用机器对机器 (M2M) 通信,进一步提升自动化程度。 这种通信能够实现数据访问,这些数据是由分布在生产现场的大量不同传感器节点提供。 对这些数据进行长期深入分析,最终将提高现代工厂环境的效率和生产率。 能够支持千兆数据速率的以太网经过考验已成为主要候选技术,并已得到广泛部署。 它不仅能够满足速度和带宽要求,具备在各种环境条件下(例如高温、静电放电、振动)必需的稳定性,还提供低延迟特性,这种特性对于实时控制/分析是必不可少的。 Marvell 开发了非常精密的千兆以太网收发器,主要针对此类应用,性能更加出色。

    在数据中心,情况也在发生着变化,但在这种场景下,涉及的原则有些不同。 数据中心更加侧重于如何处理更大的数据量,同时控制相关的资本和运营开支。 Marvell has been championing a more cost effective and streamlined approach through its Prestera® PX Passive Intelligent Port Extender (PIPE) products. 当今的数据中心工程师采用了模块化方法,以部署能够满足其特定需求的网络基础设施,而无需提高不必要的复杂性,避免增加成本和功耗。 由此设计出的解决方案具有充分可扩展性,不仅更加经济实惠,而且能效更低。

    In the wireless domain, there is ever greater pressure being placed upon WLAN hardware - in the home, office, municipal and retail environments. 随着用户密度增大,整体数据容量随之增加,网络运营商和服务提供商必须能够适应目前在用户行为方面发生的变化。 Wi-Fi 连接的用途不再限于下载数据,还更多地用于上传数据,这将是个重要的考虑因素。 很多不同应用都将需要数据上传,包括增强现实游戏、高清视频内容共享和基于云的创新活动等。 为了满足这种需求,Wi-Fi 技术必须在上行链路和下行链路上都展现出增强的带宽容量。

    倍受期待的 802.11ax 协议的推出必将全盘改变 Wi-Fi 技术的实施方式。 Not only will this allow far greater user densities to be supported (thereby meeting the coverage demands of places where large numbers of people are in need of Internet access, such as airports, sports stadia and concert venues), it also offers greater uplink/downlink data capacity - supporting multi-Gigabit operation in both directions. Marvell 期望通过近期发布的千兆位级 802.11ax Wi-Fi 系统单晶片 (SoC),进一步推动 Wi-Fi 技术发展,它是业界首款可在上行链路和下行链路上都提供正交频分多址接入 (OFDMA) 和多用户 MIMO 运行的产品。 欲了解有关 Marvell 产品如何应对全球数据传输激增的更多信息,请访问 www.marvell.com

    数据处理方式新变革

    作者:Marvell 公关团队

    现代社会对数据的要求与日俱增,以及新模式层出不穷,对数据处理方式提出了新的挑战。 The rapidly rising volume of data that is now being uploaded and downloaded from the cloud (such as HD video or equally data-intensive immersive gaming content) is putting incredible strain onto existing network infrastructure - testing both the bandwidth and data density speeds that are supported. 

    增强现实 (AR) 和虚拟现实 (VR) 的兴起将需要相当可观的处理能力,但同时也要求极低的延迟水平,以防止造成滞后效应。 广泛推出的物联网基础设施、互联汽车、机器人以及工业自动化系统等,对处理性能和延迟方面的要求也将非常苛刻,而目前的网络架构基本上难以支持如此多的高要求。

    将数据从网络边缘传输回集中式服务器(反之亦然)需要时间,所以在某些应用中会增加延迟时间,让人难以接受。 所有这些都意味着,数据处理需要做出根本性的改变。 未来,不是所有处理资源都集中在网络中心,而是需要分布性更强的模式。 Though the role of centralized servers will unquestionably still be important, this will be complemented by remote servers that are located at the edge of the network - thus making them closer to the users themselves, and thereby mitigating latency issues which is critical for time-sensitive data. 

    相关数据表明: 到 2020 年,将有约 45% 的雾计算生成的数据会在网络附近或边缘进行存储、处理和分析并随后进行操作。 数据中心将与之协同运作,开始利用存储内处理能力。 在这里,为了缓解 CPU 拥塞程度并减少网络延迟,会开始将数据处理资源放置在更靠近存储驱动器的位置。 这样就不需要连续将大量数据传输到存储储备以及从存储储备中将大量数据转移出去,可以通过处理任务来处理这些数据,而不是在存储控制器内部进行。

    从传统数据中心到基于边缘的计算的过渡,以及存储内处理的兴起,都将需要新型处理器设备。 除了提供高吞吐量、低延迟应用所需的运行性能之外,这些设备还需要满足实现边缘部署的功耗、成本和空间限制。

    通过提供非常先进的基于 ARMADA® Arm 的多核嵌入式处理器产品组合,Marvell 能够为业界提供处理解决方案,帮助工程师应对上述挑战。 这些集成电路集高集成度、高性能以及低功耗运行的特点于一身。 Marvell 以 ARMADA 为基础,与有技术合作的伙伴携手,共同开发了 MACCHIATObin™ 和 ESPRESSObin® 社区开发板。 Marvell 社区开发板均采用 64 位 ARMADA 处理器,为开发人员和设计人员提供了高性能单板计算平台以及开源软件,适用于众多网络、存储和连接应用。 这些开发板为用户提供了从零开始开发专有边缘计算应用所需的基本处理能力以及各种连接选项。

    PicoCluster 公司推出的 NFV PicoPod 整合了总共 6 块 MACCHIATObin 开发板,以及一个 Marvell 高密度 Prestera DX 14 端口 10Gb 以太网交换机集成电路,是 ARMADA 技术的另一个应用案例。 这一超紧凑的单元为工程师提供了一个高性价比的节能平台,在这个平台上可以实现自己的虚拟化网络应用。 Fully compliant with the OPNFV Pharos specification, it opens up the benefits of NFV technology to a much broader cross section of potential customers, allowing everyone from the engineering teams in large enterprises all the way down to engineers who are working solo to rapidly develop, verify and deploy virtual network functions (VNFs) - effectively providing them with their own ‘datacenter on desktop’. 

    Marvell 物联网企业边缘网关技术与 Google Cloud IoT Core 平台的结合是另一种实现方式,通过这一方式,可以更智能地管理网络外围设备。 这样做的好处是,可以采用最有效的方式管理将在未来几年安装的预计数百亿个互联的物联网节点,并从核心网络的处理能力中分流大部分工作负载,仅在完全有必要时才动用这些核心网络处理能力。Marvell is moving the world's data 欲了解有关 Marvell 产品如何处理全球数据的更多信息,请访问 www.marvell.com

    重新定义联网家庭

    作者:Sree Durbha,Marvell 智能连接业务负责人

    各方面“联网家庭”的概念已经讨论了 20 多年。 然而,其广泛普及所历经的时间,却远远超过人们最初的设想。 很长一段时间内,部署活动看起来都很有限,范围限于数量相对较少的高价值设备。 这类安装实施起来普遍较为复杂,且其操作并不人性化。 非常重要的是,他们是由一系列来自不同供应商的独立子系统融合而成,并非一个完整的通用系统。

    尽管智能手机和平板电脑开始让家庭自动化显得触手可及,但市场分化意味着家庭内安装的自动化技术,在各个单独方面还是基于本身的特有机制,需要单独的应用程序进行控制。 因此,家庭自动化系统对于操作的人来说,总是很不方便且令人失望,并无疑放慢了该技术在消费者中的普及速度。 行业分化,加上不同供应商生态系统间缺乏互通,导致消费者无法真正充分利用各种不同平台的连接性能。

    该行业正在研发新的解决方案,似乎终于开始着手拓宽家庭自动化技术的人性化程度,并加速其未来的发展进程。 Apple 通过自有的 HomeKit™ 技术,尝试整合各种不同的纵向领域,将其纳入单个综合型家庭自动化生态系统,让整体运作更加简便和安全。 而通过 HomeKit 配件协议 (HAP),来自不同供应商的硬件得以融入家庭自动化体系,可以通过单个一致的完整平台,与 Apple 产品(iPhone、iPad、Apple Watch)实现交互通信。 这一任务是通过低能耗 Bluetooth® 无线技术和 IP 连接予以实现。 HomeKit 硬件和软件技术所覆盖的不同“行为”列表范围非常广。 为音频系统选择一个播放列表,打开某个房间的灯光,远程启动家用电器(例如洗衣机/烘干机),调整供暖和制冷,以及激活门禁系统等等,不胜枚举。 但是,由于所有的功能都是通过 Apple Home 应用程序或要求 Siri(而非通过多种不同应用程序)进行控制,现在可以实现协调工作。 例如,可以进行设置,要求如果房间拉上窗帘,则同时打开灯光,或根据特定的音乐播放列表改变环境照明。

    Marvell 通过支持 Apple HomeKit 将自身置于下一代智能家庭发展的前沿领域。 Marvell 的无线 SoC 系列设备是三年前业内新面世的经过最初的 HAP 规范安全认证的产品,且一直处于行业技术前沿,而崭新一代产品 HomeKit 配件协议 Release 9 版本 (HAP R9) 的设计规格,更进一步证实了 Marvell 的这种强大实力。 低功耗 88MW30x ICs 都装配集成的微控制器,配备 Cortex®-M4 processing core 处理核,以及单频 IEEE 802.11n Wi-Fi® 功能。 此次真正的革命性变化是 Marvell SoC 的 iCloud 执行证书,可以通过语音远程控制服从 HomeKit 的设备,及使用 iCloud® 远程访问来控制 HomeKit 应用程序。 这意味着服务家庭自动化市场的 OEM 将可以让他们的系统更加简洁和方便,以通过 iCloud 可以非常好地实现功能。 其结果就是新的用例已经成为可能。 例如,您可以在下班回家途中使用 Apple Home 应用程序(或 Siri® 语音控制)远程启动恒温器来给房间供暖或制冷,并设定回家时想要的合适温度。

    This technology is showcased in the Marvell® EZ-Connect® HAP software development kit (SDK), which is designed to facilitate the implementation of HomeKit-enabled home automation accessories - accelerating our OEM customers’ design cycles and allowing products to be brought to market more quickly. 为了补充 802.11n 无线连接的不足,其中集成的桥接功能还可使用其他 RF 协议(例如低能耗蓝牙技术)实现与设备之间的桥接。 例如,Marvell 已与一家排名靠前的低能耗蓝牙供应商达成合作关系,提供一个组合模块参考设计,目前该产品已经上市,可以通过 Marvell 的模块供应商合作伙伴之一 Azurewave 进行购买。 我们在安全、加密和存储分区方面的重点研究实现了安全的空中固件升级,这样客户应用可以通过外部闪存安全运行,同时在空中时保持加密状态。 Marvell 的 SDK 还支持 Amazon 广受欢迎的 AWS 云平台以及 Google 的 Weave/Cloud 平台作为替代。 为搭配 SDK,Marvell 计划向 OEM 提供所有必要的附件,帮助他们的产品以更快、更轻松的方式通过 HomeKit 认证程序,并尽快投放市场。 Marvell 还会提供辅助作用的项目范例。

    Marvell 理解强劲的软件解决方案,对于实现毫无障碍的家庭自动化用户体验,有着何等至关重要的作用,并已开发出行业排名靠前的软件性能来支持 Apple HomeKit。 这让 Marvell 在激烈的竞争中始终保持佼佼者地位。

    USR联盟:促成一个开放的多芯片模块 (MCM) 生态系统

    By Gidi Navon, Senior Principal Architect, Marvell

    USRA logo为了适应不断提高的带宽需求、设计的复杂性、新工艺的出现以及多学科技术的整合等要求,半导体行业正在经历指数性增长和更加快速的变化。 所有这些又都是在越来越短的开发周期和越来越激烈的竞争背景下发生的。 在软件和硬件等技术驱动的其他产业领域,正在通过建立一系列开放的联盟和开放的标准来解决类似的挑战。 This blog does not attempt to list all the open alliances that now exist --  the Open Compute Project, Open Data Path and the Linux Foundation are just a few of the most prominent examples. 但目前还有一个技术领域没有采纳这种开放式的合作,这就是多芯片模块 (MCM),它是将多个半导体晶片封装在一起,从而在一个单一封装中能够创建一个完整的系统。

    MCM的概念已经在业界存在了一段时间,这种方式具有多种技术和市场方面的优势,其中包括:

    • Improved yield - Instead of creating large monolithic dies with low yield and higher cost (which sometimes cannot even be fabricated), splitting the silicon into multiple die can significantly improve the yield of each building block and the combined solution. 更高的良率最终转化为成本的降低。
    • Optimized process - The final MCM product is a mix-and-match of units in different fabrication processes which enables optimizing of the process selection for specific IP blocks with similar characteristics.
    • Multiple fabrication plants - Different fabs, each with its own unique capabilities, can be utilized to create a given product.
    • Product variety - New products are easily created by combining different numbers and types of devices to form innovative and cost‑optimized MCMs.
    • Short product cycle time - Dies can be upgraded independently, which promotes ease in the addition of new product capabilities and/or the ability to correct any issues within a given die. 例如,可以给新产品集成全新的 I/O 接口,而无需重新设计解决方案中那些稳定运行且不需改变的部分,从而避免浪费时间和金钱。
    • Economy of scale - Each die can be reused in multiple applications and products, increasing its volume and yield as well as the overall return on the initial investment made in its development.

    Sub-dividing large semiconductor devices and mounting them on an MCM has now become the new printed circuit board (PCB) - providing smaller footprint, lower power, higher performance and expanded functionality. 

    现在,我们可以想象一下,上面列出的优势并不局限于某家芯片供应商,而是可以由整个行业共享。 通过开放和标准化晶片之间的接口,就能引入一个真正的开放平台,而在此平台下,来自不同公司且具有各自技术专长的设计团队,可以创造出任何单打独斗的公司所不能及的各种新产品。

    这正是 USR 联盟所要倡导实施的所在。 USR 联盟已经定义了离 (USR) 链路,针对单一封装中所含组件之间的非常短距离通信进行了优化。 现有的跨越封装边界和连接器的超短距离 (VSR) PHY 需要面对一些不属于封装内部的技术挑战,而 USR 链路则可以提供更高的带宽,更低的功耗和更小的芯片尺寸。 此外,USR PHY 是基于多线差分信号传输技术,专门针对 MCM 环境进行了优化。

    有很多应用都可以通过 USR 链路实施, 例如 CPU、交换机和路由器、FPGA、DSP、模拟组件和各种长距离电光接口等等。可能的 MCM 布局范例 图 1: 可能的 MCM 布局范例 

    作为 USR 联盟的一个积极推动者,Marvell 公司正在努力建造一个关于互操作组件、互连、协议和软件的生态系统,以帮助半导体产业为市场带来更多价值。  USR 联盟正在与业界和其他标准开发组织合作,共同创建 PHY、MAC 和软件标准以及互操作性协议,同时为了确保广泛的互操作性,也在推动开发关于 USR 应用(包括认证计划)的完整生态系统。

    Marvell 携手 Sentinel 和 Sartura,在 OpenWrt 峰会展示强大的安全软件和实施支持

    作者:Maen Suleiman,Marvell 软件产品线高级经理

    得益于在 OpenWrt 和安全领域与领先企业的合作,Marvell 将向参加 OpenWrt 峰会(捷克共和国布拉格,10 月 26-27 日)的来宾展示 Marvell ARMADA® 多核处理器的最新技术进展。通过与强有力的伙伴 Sartura 和 Sentinel 的合作,这些技术进步将通过 Marvell 的网络社区板系列产品展现实力,该产品通过运行日益普及且多功能的 OpenWrt 操作系统,加上非常先进的安全软件,支持 64 位基于 Arm® 的 Marvell ARMADA 处理器设备。 Marvell 希望这些新产品能够帮助工程师应对建设下一代用户端设备 (CPE) 和 uCPE 平台时所面临的主要挑战。

    活动中 Sentinel 和 Sartura 两个展位都会有 Marvell MACCHIATObin™ 板(配备四核 ARMADA 8040,可实现高达 2GHz 的运行速度)和 Marvell ESPRESSObin™ 板(配备双核 ARMADA 3700,更低功耗的处理器,运行速度达到 1.2GHz)的范例展示。

    置于 Sartura 展位的样品板将展示 Marvell MACCHIATObin/ESPRESSObin 平台的开源代码 OpenWrt 产品,并将示范工程师应该如何充分利用该公司的 OpenWrt 集成性能。 该性能已经证实非常具有使用价值,可以帮助工程师进一步加快项目开发速度,并在各方面实现此类项目设定的初始目标。 Sartura 团队可以用工程师的初始 CPE 设计搭载 ARMADA,并提供需纳入最终产品的产品级软件。

    Marvell 也会在 Sentinel 展位展示 MACCHIATObin/ESPRESSObin 板。 这些都是高度优化安全软件的代表。 Using this security software, companies looking to employ ARMADA based hardware in their designs will be able to ensure that they have ample protection against the threat posed by malware and harmful files - like WannaCry and Nyetya ransomware, as well as Petya malware, etc. 这种保护依托 Sentinel 的文件验证服务 (FVS),这种服务会在 HTTP、POP 和 IMAP 文件通过设备向客户端传输时检查所有的文件。 随后,任何被认为带有恶意性质的文件都会被锁定。 这种安全技术非常适合 CPE 网络基础架构和边缘计算,以及物联网的部署。 Sentinel’s FVS technology can also be implemented on vCPE/uCPE as a security virtual network function (VNF), in addition to native implementation over physical CPEs - providing similar protection levels due to its extremely lightweight architecture and very low latency. FVS 负责确认下载请求,并随后分析下载的数据。 面这款软件包可以用于 CPE 和 NFV 设备,在各方面基于 Linux 的内嵌式操作系统上运行,但这些设备须满足非常低的硬件要求并提供必要的功能。

    Marvell 正在通过上述各种合作项目,围绕其 ARMADA 产品建立广泛的生态系统。 此后,Marvell 将能够支持未来呈现巨大差异化的安全、高性能 CPE 和 uCPE/vCPE 系统的发展。

    汽车领域正在遭遇自 150 年前内燃机发明以来技术进步历程中非常深刻的一场变革。 自动化程度的日益提高将会改变我们对汽车和乘车出行的看法。 It won't be just a matter of getting from point A to point B while doing very little else -- we will be able to keep on doing what we want while in the process of getting there. 

    As it is, the modern car already incorporates large quantities of complex electronics - making sure the ride is comfortable, the engine runs smoothly and efficiently, and providing infotainment for the driver and passengers. 此外,在我们目前开始购买的汽车中,融合的特性和功能也不再是固定不变的。 It is increasingly common for engine control and infotainment systems to require updates over the course of the vehicle's operational lifespan. 

    事实证明,此类更新对以太网连接最初应用于汽车领域很有帮助。 宝马和大众等汽车先进品牌发现,通过将小型以太网装置安装到汽车底盘中,取代虽然成熟但速度慢得多的控制器局域网络 (CAN) 总线,可以显著提高服务中心机修工执行上传的速度。 因此,传输时间从几小时缩短到了几分钟。

    随着越来越多的可升级电子控制单元 (ECU) 不断涌现,对现有的车载网络技术产生了更大的压力,以太网网络本身也随之扩展。 与之相对应,半导体行业已开发出解决方案并随之制定了网络标准,其最初的开发目的是用于相对来说电动原件很少的办公室环境,而如今其功能更强,更能满足汽车制造商的严格要求。 The CAN and Media Oriented Systems Transport (MOST) buses have persisted as the main carriers of real-time information for in-vehicle electronics - although, now, they are beginning to fade as Ethernet evolves into a role as the primary network inside the car, being used for both real-time communications and updating tasks. 

    在这个环境中,所采用技术的重量要求非常严格,重量越轻越能节省燃料,在单个网络中完成通讯任务的能力(尤其若设备只需一对重量相对更轻的铜线)具有非常大大的运行优势。 另外,保持连接器足迹更小也是这种背景下至关重要的一点,更便于增加传感器的部署数量(例如摄像头、雷达和 LiDAR 收发器),现在这些设备已经装满整个车身,用于驾驶辅助/半自动驾驶。 采用非屏蔽的双绞线有助于实现这个目标。

    图像传感、雷达和 LiDAR 功能都会生成大量的数据。 因此,数据传输能力在目前和今后都将是车载以太网网络的一大关键要素。 汽车行业对此做出快速响应,首先提供 100 Mbit/s 的收发器,后续又推出功能更强大且符合标准的 1000 Mbit/s 产品。

    但是,仅提供更大带宽还是不够。 为了让汽车制造商无需牺牲必要的即时性能,实现可靠的控制,相关国际标准委员会已经制定了协议,确保数据的及时传输。 时效性网路 (TNS) 让应用能够使用虚拟通道上的保留带宽,以便确保在可预测的时间期限内完成传输。 不太重要的流量则可利用常规以太网的优化服务,使用剩余的未保留带宽。

    行业内包括 Marvell 在内的一些更具前瞻性思维的半导体供应商,已经通过在车载优化以太网交换机中增加深度包检测 (DPI) 等功能,采用三元内容可寻址存储器 (TCAM) 等设备进一步提高即时性能。 借助 DPI 机制,硬件能够在每个数据包到达交换机输入端时对其进行深入检测,即时决定如何处理该消息。 包检测技术通过捕捉某种类型的消息支持实时调试功能,并通过避免处理器的干扰显著降低部署过程中的应用程序延迟。

    远程管理帧支持也是汽车以太网领域的另一个具有重大意义的协议创新。 这些帧让系统控制器能够直接控制交换机状态。 For example, a system controller can automatically power down I/O ports when they are not needed - a feature that preserves precious battery life. 

    对于核心以太网标准的调试,及其恢复能力的提高,促进更多功能组不断增加,进一步推动汽车技术的变革,将汽车从一种简单的运输方式,转变为未来设想中数据丰富的自主移动平台。

    Wi-Fi 20 周年庆 - 第 3 篇

    作者:Prabhu Loganathan,Marvell 互联事业部市场营销高级总监

    1997 年实现标准化的 Wi-Fi 改变了我们使用计算技术的方式。 Today, almost every one of us uses a Wi-Fi connection on a daily basis, whether it's for watching a show on a tablet at home, using our laptops at work, or even transferring photos from a camera. 每周都会有数百万支持 Wi-Fi 的产品发货,而且似乎这种技术还在持续拓展新的设备种类。

    Wi-Fi 低调问世以来,发展迅猛。 While the initial standard allowed for just 2 Mbit/s data rates, today's Wi-Fi implementations allow for speeds in the order of Gigabits to be supported. 我们介绍 Wi-Fi 历史的博客系列由三部分组成,这是最后一篇,将讨论无线标准的未来趋势。

    Gigabit Wireless


    The latest 802.11 wireless technology to be adopted at scale is 802.11ac. 它扩展了 802.11n 标准,具体来说是在 5.8 GHz 频段实现了改进,而 802.11n 技术用于 2.4 GHz 频段,以确保向后兼容性。

    由于采用 5.8 GHz 频段,802.11ac 能够获得宽大的 160 Hz 通道带宽,这在已经拥挤的 2.4 GHz 频段中是无法实现的。 此外,波束成形技术和多达 8 路 MIMO 数据流也提高了可支持的速度。 根据配置的不同,数据速率最小为 433 Mbit/s,若路由器和最终用户设备都拥有多个天线,非常大可达数千兆。

    If that's not fast enough, the even more cutting edge 802.11ad standard (which is now starting to appear on the market) uses 60 GHz ‘millimeter wave’ frequencies to achieve data rates up to 7 Gbit/s, even without MIMO propagation. 该技术的主要缺点是,在 60 GHz 频率下,无线范围和穿透能力大大降低。

    Looking Ahead


    Now that we've achieved Gigabit speeds, what's next? 除了高速之外,IEEE 802.11 工作组也认识到,低速、高能效的通信实际上也是极具发展潜力的领域。 虽然 Wi-Fi 一直以来都是一种相对功耗较高的标准,但即将问世的协议将具备相关属性,让物联网 (IoT) 市场等目标领域能够以更加节能的方式进行通讯。

    20 Years and Counting


    Although it has been around for two whole decades as a standard, Wi-Fi has managed to constantly evolve and keep up with the times. 从拨号时代到宽带普及,再到智能手机,现在我们进入了物联网的早期阶段,Wi-Fi 一直在开发新技术,以适应市场的需求。 如果历史可以给予我们启示,那么似乎可以肯定,Wi-Fi 将在未来的很多年里伴随着我们。

    利用 NVMe 充分释放闪存的潜能

    作者:Jeroen Dorgelo,Marvell 存储事业部战略总监

    当今的闪存驱动器存在一个鲜为人知的小秘密,那就是其中很多闪存仍在使用老式接口。 虽然 SATA 和 SAS 协议自最初推出之时已历经数代的发展,但它们仍然是基于数十年前针对传统磁碟式硬盘的设计理念。 这些传统协议成为了限制当今 SSD 发挥潜能的瓶颈。

    NVMe 是专为 SSD 设计的崭新存储接口标准, 采用了大规模并行传输架构,可让当今的 SSD 发挥出全部性能潜力。 由于价格和兼容性的影响,NVMe 经过了一些时间才在市场上有所起色,现在终于获得了成功。

    传统串行连接技术

    SATA 仍然是当前最常见的存储接口。 无论是硬盘驱动器,还是日益盛行的闪存存储设备,大部分都是采用 SATA 接口来工作。 The latest generation of SATA - SATA III – has a 600 MB/s bandwidth limit. 虽然这个带宽足已满足日常消费类应用的需求,但对于企业服务器而言,还是远远不够。 即便是在 I/O 密集型的消费类应用场景下(例如视频编辑)也可能受限于这个带宽。

    SATA 标准最初在 2000 年作为旧式 PATA 并行接口标准的串行替代标准而发布。 SATA 采用高级主机控制接口 (AHCI) 技术,单个命令队列的深度为 32 个命令。 此命令队列架构非常适合传统的磁碟式硬盘存储,但用于闪存时,却存在较多限制。

    如果说 SATA 是消费类驱动器的标准存储接口,那么 SAS 则在企业应用中更为常见。 Released originally in 2004, SAS is also a serial replacement to an older parallel standard SCSI. Designed for enterprise applications, SAS storage is usually more expensive to implement than SATA, but it has significant advantages over SATA for data center use - such as longer cable lengths, multipath IO, and better error reporting. SAS 的带宽限制也更高,为 1200MB/s。

    尽管 SAS 支持的队列深度为 254 个命令,大大多于 SATA 的 32 个,但和 SATA 相同,SAS 依然只支持单个命令队列。 虽然 SAS 具有更深的命令队列和更高的带宽限制,总体性能优于 SATA,但也远非理想的闪存接口。

    NVMe - Massive Parallelism 

    NVMe 于 2011 年推出,从设计之初就充分考虑到闪存存储的需求。 NVMe 由多家存储公司联合开发,其主要目标是克服 SATA 和 SAS 对闪存性能造成的瓶颈。

    如前所述,SATA 受限于 600MB/s 而 SAS 受限于 1200MB/s 带宽,与之相反,NVMe 是在 PCIe 总线上运行,其带宽理论上只受限于 PCIe 总线速度。 当前的 PCIe 标准每条通道提供 1GB/s 甚至更高带宽,而 PCIe 连接一般都会提供多条通道,其总线速度几乎从未对基于 NVMe 的 SSD 构成阻碍。

    NVMe 为实现大规模并行计算而设计,提供多达 64,000 个命令队列,每个命令队列的队列深度高达 64,000。 这种并行计算非常适合闪存存储的随机存取特性,也适合当今计算机中的多内核、多线程处理器。 NVMe 的协议经过合理化设计,与 AHCI 相比,它的优化命令集可通过更少的操作完成更多的工作。 与 SATA 或 SAS 相比,NVMe 的 IO 操作需要的命令通常更少,从而能够减少延迟。 对于企业客户而言,NVMe 还支持很多企业存储功能,例如多路径 IO、可靠的错误报告和管理。

    凭借高速度和低延迟的优势,加上处理高 IOPS 的能力,NVMe SSD 成为企业数据中心的一大热点。 非常重视低延迟和高 IOP 的企业(例如高频率贸易公司和数据库,以及网络应用托管公司)是最初尝试 NVMe SSD 技术的公司,也是非常忠实的支持者。

    采用 NVMe 的障碍

    虽然 NVMe 具有很高的性能,但从历史上来看,它也被视为一种成本相对较高的技术。 高成本影响了它在消费级存储领域的普及。 相对来说,当 NVMe 技术刚刚出现的时候,支持它的操作系统并不多,而且其价格高企,对一般消费者来说更加不具吸引力,不管怎样,很多消费者其实并不能用到其速度更快的这一优势。

    但这一切正在改变。 NVMe SSD 的价格正在逐渐降低,在某些情况下,其价格甚至可与 SATA 驱动器相媲美。 原因不仅是市场的力量,也得益于新的技术创新,例如无 DRAM 型 NVMe SSD。

    鉴于 DRAM 是 SSD 物料清单 (BoM) 成本中的大项,无 DRAM 型 SSD 成本可以降至更低,价格也更有竞争力。 随着 NVMe 1.2 发布,其主机存储缓冲机制 (HMB) 的支持使得无 DRAM 型 SSD 能够借用主机系统内存作为 SSD 的 DRAM 缓冲区,从而带来了更出色的性能。 无 DRAM 型 SSD 充分利用 HMB 支持,能够达到与基于 DRAM 的 SSD 相似的性能,同时节省成本、空间和能耗。

    NVMe SSD 还比以往的协议更加节能。 NVMe 协议本身已经非常高效,但它运行的 PCIe 链路可能会消耗大量的待机功率。 新型 NVMe SSD 支持高效、自动的睡眠状态传输,让设备可以达到甚至低于 SATA SSD 的能耗水平。

    所有这些都意味着,NVMe 比以往更加实用,可以用于各种各样的用例,包括大数据中心(由于 SSD 成本更低可以节省资本支出,又因为功耗更低可以节省营业费用),以及功率敏感的移动/便携应用设备,例如笔记本电脑、平板电脑和智能手机,这些现在都可以考虑使用 NVMe 技术。

    满足速度需求

    对于速度的追求在企业应用中是不争的趋势,但在消费类应用中,是不是真的需要 NVMe 提供的那种速度呢? 对于曾经安装过额外内存、购买过更大硬盘驱动器(或 SSD)、订购过更快互联网连接的任何用户而言,答案不言而喻。

    如今的消费类用例尚未逼近 SATA 驱动器的极限,非常具有可能的一部分原因是 SATA 仍是消费类存储最常用的接口。 当前的视频录制和编辑、游戏和文件服务器应用程序,则已经开始迫近消费类 SSD 的极限性能,而今后的用例则必将推动其继续发展。 随着 NVMe 的价位现在逐渐接近 SATA,我们必须构建能够经受未来考验的存储产品。

    通过支持 ESPRESSObin 和 MACCHIATObin 社区平台上的 Google Cloud IoT Core Public Beta,将 IoT 技术扩展到企业边缘

    By Aviad Enav Zagha, Sr. Director Embedded Processors Product Line Manager, Networking Group, Marvell

    Espresso Bin and Macchiato Bin Cards Though the projections made by market analysts still differ to a considerable degree, there is little doubt about the huge future potential that implementation of Internet of Things (IoT) technology has within an enterprise context. It is destined to lead to billions of connected devices being in operation, all sending captured data back to the cloud, from which analysis can be undertaken or actions initiated.

    In order to put the least possible strain on cloud-based resources, we believe the best approach is to divest some intelligence outside the core and place it at the enterprise edge, rather than following a purely centralized model. This arrangement places computing functionality much nearer to where the data is being acquired and makes a response to it considerably easier. IoT devices will then have a local edge hub that can reduce the overhead of real-time communication over the network. Rather than relying on cloud servers far away from the connected devices to take care of the ‘heavy lifting’, these activities can be done closer to home.

    In order to accelerate the widespread propagation of IoT technology within the enterprise environment, Marvell now supports the multifaceted Google Cloud IoT Core platform. Cloud IoT Core is a fully managed service mechanism through which the management and secure connection of devices can be accomplished on the large scales that will be characteristic of most IoT deployments. 

    Through its IoT enterprise edge gateway technology, Marvell is able to provide the necessary networking and compute capabilities required (as well as the prospect of localized storage) to act as mediator between the connected devices within the network and the related cloud functions. By providing the control element needed, as well as collecting real-time data from IoT devices, the IoT enterprise gateway technology serves as a key consolidation point for interfacing with the cloud and also has the ability to temporarily control managed devices if an event occurs that makes cloud services unavailable. In addition, the IoT enterprise gateway can perform the role of a proxy manager for lightweight, rudimentary IoT devices that (in order to keep power consumption and unit cost down) may not possess any intelligence. Through the introduction of advanced ARM®-based community platforms, Marvell is able to facilitate enterprise implementations using Cloud IoT Core. The recently announced Marvell MACCHIATObin™ and Marvell ESPRESSObin™ community boards support open source applications, local storage and networking facilities. At the heart of each of these boards is Marvell’s high performance ARMADA® system-on-chip (SoC) that supports Google Cloud IoT Core Public Beta. 

    Consequently, mediation between IoT devices and the cloud will be needed, as will cost-effective processing and management.

    Please visit MACCHIATObin Wiki and ESPRESSObin Wiki for instructions on how to connect to Google’s Cloud IoT Core Public Beta platform.

    Wi-Fi 20 周年庆 - 第 2 篇

    作者:Prabhu Loganathan,Marvell 互联事业部市场营销高级总监

    This is the second instalment in a series of blogs covering the history of Wi-Fi®. While the first part looked at the origins of Wi-Fi, this part will look at how the technology has progressed to the high speed connection we know today. 

    Wireless Revolution 

    Hotspots began popping up at coffee shops, airports and hotels as businesses and consumers started to realize the potential for Wi-Fi to enable early forms of what we now know as mobile computing.

    Thanks to the IEEE® 802.11 working group's efforts, a proprietary wireless protocol that was originally designed simply for connecting cash registers (see previous blog) had become the basis for a wireless networking standard that was changing the whole fabric of society. 

    As broadband speeds became the norm, consumer's computer usage habits changed accordingly.

    Even in the early 2000's, the speed that 802.11b could support was far from cutting edge. On the wired side of things, 10/100 Ethernet was already a widespread standard. At 100 Mbit/s, it was almost 10 times faster than 802.11b's nominal 11 Mbit/s speed. 802.11b's protocol overhead meant that, in fact, maximum theoretical speeds were 5.9 Mbit/s. In practice though, as 802.11b used the increasingly popular 2.4 GHz band, speeds proved to be lower than that still. Interference from microwave ovens, cordless phones and other consumer electronics, meant that real world speeds often didn't reach the 5.9 Mbit/s mark (sometimes not even close). 

    802.11G

    Though 802.11g would use the 2.4 GHz frequency band just like 802.11b, it was able to achieve speeds of up to 54 Mbit/s.

    That crown goes to 802.11a, which had done it back in 1999. However, 802.11a used a separate 5.8 GHz frequency to achieve its fast speeds. While 5.8 GHz had the benefit of less radio interference from consumer electronics, it also meant incompatibility with 802.11b.

    This was crucial, as 802.11b had already established itself as the main wireless standard for consumer devices by this point.

    802.11n 

    Introduced in 2009, 802.11n made further speed improvements upon 802.11g and 802.11a. Operating on either 2.4 GHz or 5.8 GHz frequency bands (though not simultaneously), 802.11n improved transfer efficiency through frame aggregation, and also introduced optional MIMO and 40 Hz channels - double the channel width of 802.11g. 

    At the low end, if it was operating in the same type of single antenna, 20 Hz channel width configuration as an 802.11g network, the 802.11n network could achieve 72 Mbit/s. If, in addition, the double width 40 Hz channel was used, with multiple antennas, then data rates could be much faster - up to 600 Mbit/s (for a four antenna configuration). 

    The third and final blog in this series will take us right up to the modern day and will also look at the potential of Wi-Fi in the future.

    Wi-Fi 20 周年庆 - 第 1 篇

    作者:Prabhu Loganathan,Marvell 互联事业部市场营销高级总监

    You can't see it, touch it, or hear it - yet Wi-Fi® has had a tremendous impact on the modern world - and will continue to do so. From our home wireless networks, to offices and public spaces, the ubiquity of high speed connectivity without reliance on cables has radically changed the way computing happens. It would not be much of an exaggeration to say that because of ready access to Wi-Fi, we are consequently able to lead better lives - using our laptops, tablets and portable electronics goods in a far more straightforward, simplistic manner with a high degree of mobility, no longer having to worry about a complex tangle of wires tying us down.

    This first in a series of blogs will look at the history of Wi-Fi to see how it has overcome numerous technical challenges and evolved into the ultra-fast, highly convenient wireless standard that we know today.

    Unlicensed Beginnings 

    While we now think of 802.11 wireless technology as predominantly connecting our personal computing devices and smartphones to the Internet, it was in fact initially invented as a means to connect up humble cash registers. In the late 1980s, NCR Corporation, a maker of retail hardware and point-of-sale (PoS) computer systems, had a big problem. Its customers - department stores and supermarkets - didn't want to dig up their floors each time they changed their store layout. 

    They were set the challenge of creating a wireless communication protocol. These engineers succeeded in developing ‘WaveLAN’, which would be recognized as the precursor to Wi-Fi. Rather than preserving this as a purely proprietary protocol, NCR could see that by establishing it as a standard, the company would be able to position itself as a leader in the wireless connectivity market as it emerged.

    Wireless Ethernet 

    Though the 802.11 wireless standard was released in 1997, it didn't take off immediately. Slow speeds and expensive hardware hampered its mass market appeal for quite a while - but things were destined to change. 10 Mbit/s Ethernet was the networking standard of the day. The IEEE 802.11 working group knew that if they could equal that, they would have a worthy wireless competitor. In 1999, they succeeded, creating 802.11b. This used the same 2.4 GHz ISM frequency band as the original 802.11 wireless standard, but it raised the throughput supported considerably, reaching 11 Mbits/s. Wireless Ethernet was finally a reality. 

    Thanks to cheaper equipment and better nominal ranges, 802.11b proved to be the most popular wireless standard by far. But, while it was more cost effective than 802.11a, 802.11b still wasn't at a low enough price bracket for the average consumer.

    Apple was launching a new line of computers at that time and wanted to make wireless networking functionality part of it. The terms set were tough - Apple expected to have the cards at a $99 price point, but of course the volumes involved could potentially be huge.

    PC makers saw Apple computers beating them to the punch and wanted wireless networking as well.

    Working with engineers from Lucent, Microsoft made Wi-Fi connectivity native to the operating system. Users could get wirelessly connected without having to install third party drivers or software. With the release of Windows XP, Wi-Fi was now natively supported on millions of computers worldwide - it had officially made it into the ‘big time’.

    模块化网络对数据中心升级具有性价比

    作者:Yaron Zimmerman,Marvell 公司高级职员产品线经理

    To support the server-to-server traffic that virtualized data centers require, the networking spine will generally rely on high capacity 40 Gbit/s and 100 Gbit/s switch fabrics with aggregate throughputs now hitting 12.8 Tbit/s. But the ‘one size fits all’ approach being employed to develop these switch fabrics quickly leads to a costly misalignment for data center owners.

    The switch can aggregate the data from lower speed network interfaces and so act as a front-end to the core network fabric. But such switches tend to be far more complex than is actually needed - often derived from older generations of core switch fabric. They perform a level of switching that is unnecessary and, as a result, are not cost effective when they are primarily aggregating traffic on its way to the core network’s 12.8 Tbits/s switching engines. The heightened expense manifests itself not only in terms of hardware complexity and the issues of managing an extra network tier, but also in relation to power and air-conditioning. It is not unusual to find five or more fans inside each unit being used to cool the silicon switch.

    An attractive feature of this standard is the ability to allow port extenders to be cascaded, for even greater levels of modularity.

    Reference designs have already been built that use a simple 65W open-frame power supply to feed all the devices required even in a high-capacity, 48-ports of 10 Gbits/s. Furthermore, the equipment dispenses with the need for external management. The management requirements can move to the core 12.8 Tbit/s switch fabric, providing further savings in terms of operational expenditure. It is a demonstration of exactly how a more modular approach can greatly improve the efficiency of today's and tomorrow's data center implementations.

    利用硬件加密保护嵌入式存储

    作者:Jeroen Dorgelo,Marvell 存储事业部战略总监

    对于工业、军事和大量现代商业应用,数据安全性自然显得尤为重要。 虽然基于软件的加密对于消费者和企业环境而言通常运行良好,但工业和军事应用所使用的嵌入式系统背景,则通常需要一种结构更简单而本质性能更加强劲的软件。

    自我加密硬盘采用板上加密处理器在硬盘层确保数据的安全。 这样不仅能自动提高硬盘安全性,而且过程对用户和主机操作系统透明。 这种设备通过在后台自动加密数据,来提供嵌入式系统所要求的使用简洁性和弹性数据安全。

    嵌入式与企业数据安全

    嵌入式和企业存储通常都要求很强的数据安全性。 根据相关行业领域的不同,通常会涉及到客户(或可能是患者)隐私、军事数据或商业数据的安全。 数据种类不同,共性也越来越少。 嵌入式存储与企业存储的使用方式有很大的差别,因而导致解决数据安全问题的方法也大相径庭。

    企业存储通常由数据中心多层机架内互相连通的磁盘阵列组成,而嵌入式存储一般只是简单的将一块固态硬盘 (SSD) 安装到嵌入式电脑或设备之中。 企业经常会控制数据中心的物理安全,也会执行企业网络(或应用程序)的软件访问控制。 Embedded devices, on the other hand - such as tablets, industrial computers, smartphones, or medical devices - are often used in the field, in what are comparatively unsecure environments. 这种背景下的数据安全没有其他选择,只能在设备层面进行。

    基于硬件的全盘加密

    嵌入式应用的访问控制非常没有保障,这里的数据安全工作越自动化越透明越好。

    全盘、基于硬件的加密已经证实是达到这个目的最佳方法。全盘加密 (FDE) 通过自动对硬盘所有内容进行加密的方式,达到更高程度的安全性和透明度。 基于文件的加密会要求用户选择要加密的文件或文件夹,且需要提供解密的密码或秘钥,与之相对,FDE 的工作则充分透明。 所有写入硬盘的数据都会被加密,不过一旦经过验证,用户对此硬盘的访问就如同未加密硬盘一样简单。 这不仅会让 FDE 更易于使用,也意味着这是一种更可靠的加密方法,因为所有的数据都会自动加以保护。 即使用户忘记加密或没有访问权限的文件(如隐藏的文件、临时文件和交换空间)也都会自动加以保护。

    虽然 FDE 也可以通过软件技术实现,但基于硬件的 FDE 性能更好,且固有的保护特性更强。 基于硬件的 FDE 是在硬盘层以自我加密 SSD 的方式进行。SSD 控制器内含一个硬件加密引擎,也是在硬盘自身之内存储私有秘钥。

    Because software based FDE relies on the host processor to perform encryption, it is usually slower - whereas hardware based FDE has much lower overhead as it can take advantage of the drive’s integrated crypto-processor. 基于硬盘的 FDE 还可以加密硬盘的主引导记录,与之相反,基于软件的加密却不具备这种功能。

    以硬件为中心的 FDE 不仅对用户透明,对主机操作系统亦然。 他们在后台悄无声息的工作,而且运行无需任何特殊软件。 除有助于优化操作简便性之外,这也意味着敏感的加密秘钥会独立于主机操作系统和存储器进行保存,所有的私有秘钥全部存储于硬盘本身。

    提高数据安全性

    这款基于硬件的 FDE 不仅能够提供当今市场急需的透明且便于使用的加密过程,而且具备现代 SSD 特有的数据安全优势。 NAND 单元的使用寿命有限,而现代 SSD 采用先进的损耗均衡算法,来尽可能的延长使用寿命。 写入操作并不会在数据更新时覆盖原有的 NAND 单元,而是在文件更新时在硬盘中来回移动,通常的结果是同一条数据存在多个副本,分散存储于 SSD 之中。 这种损耗均衡技术非常有效,但是也让基于文件的加密和数据擦除变得更加困难,因为现在有多个数据副本需要加密或擦除。

    FDE 为 SSD 解决了加密和擦除两方面的问题。 由于所有的数据都加密,所以无需担心是否存在未加密数据残留。 另外,因为所使用的加密方式(一般为 256 位 AES)非常安全,擦除硬盘就同擦除私有秘钥一样便于操作。

    解决嵌入式数据安全问题

    嵌入式设备通常都会成为 IT 部门的一大安全挑战,因为这些设备经常在非受控环境下使用,还有可能被未授权人员使用。 虽然企业 IT 有权限执行企业范围内的数据安全政策和访问控制,但是在工业环境或现场环境中针对嵌入式设备使用这种方法却难上加难。

    针对嵌入式应用中数据安全的简易解决方案正是基于硬件的 FDE。 自我加密硬盘带有硬盘加密处理器,其处理开销非常低而且在后台运行,对用户和主机操作系统透明。 其便于使用的特性也有助于提高安全性,因为管理员不需要依靠用户执行安全政策,而且私有秘钥不会暴露给软件或操作系统。

    无线技术注定要引发汽车行业的变革

    By Avinash Ghirnikar, Director of Technical Marketing of Connectivity Business Group, Marvell

    In the early 1980s, Renault made it possible to lock and unlock the doors on its Fuego model utilizing a radio transmitter. Within a decade, other vehicle manufacturers embraced the idea of remote key-less entry and not long after that it became a standard feature.

    But the industry swiftly moved to RF technology, in order to make it easier to use. Although each manufacturer favored its own protocol and coding system, they adopted standard low-power RF frequency bands, such as 315 MHz in the US and 433 MHz in Europe. As concerns about theft emerged, they incorporated encryption and other security features to fend off potential attacks. They have further refreshed this technology as new threats appeared, as well as adding features such as proximity detection to remove the need to even press the key-fob remote's button. 

    With Bluetooth, an app on the user's smartphone can not only unlock the car doors, but also handle tasks such as starting the heater or air-conditioning to make the vehicle comfortable ready for when the driver and passengers actually get in. 

    Access to the functions located on dashboard through Bluetooth has made it possible for vehicle occupants to hook up their phone handsets easily. Initially, it was to support legal phone calls through hands-free operation without forcing the owner to buy and install a permanent phone in the vehicle itself. But the wireless connection is just as good at relaying high-quality audio so that the passengers can listen to their favorite music (stored on portable devices). We have clearly move a long way from the CD auto-changer located in the trunk. Bluetooth is a prime example of the way in which RF technology, once in place, can support many different applications - with plenty of potential for use cases that have not yet been considered. Through use of a suitable relay device in the car, Bluetooth also provides the means by which to send vehicle diagnostics information to relevant smartphone apps.

    Wi-Fi is able to provide a more robust data pipe, thus enabling even richer applications and a tighter integration with smartphone handsets. One use case that seems destined to change the cockpit experience for users is the emergence of screen projection technologies. Through the introduction of such mechanisms it will be possible to create a seamless transition for drivers from their smartphones to their cars.

    If a pothole opens up or cars have to break suddenly to avoid an obstacle, they can send out wireless messages to nearby vehicles to let them know about the situation.

    IEEE 802.11p Wireless Access in Vehicular Environments (WAVE) operates in the 5.9 GHz region of the RF spectrum, and is capable of supporting data rates of up to 27 Mbit/s. One of the key additions for transportation is scheduling feature that let vehicles share access to wireless channels based on time.

    On a freeway, the relative velocity of an approaching transmitter can exceed 150 mph. Such a transmitter may be in range for only a few seconds at most, making ultra-low latency crucial.

    Traffic signals, for example, can let vehicles know when they are likely to change state. Vehicles leaving the junction can relay that data to approaching cars, which may slow down in response. By slowing down, they avoid the need to stop at a red signal - and thereby cross just as it is turning to green. The overall effect is a significant saving in fuel, as well as less wear and tear on the brakes. In the future, such wireless-enabled signals will make it possible improve the flow of autonomous vehicles considerably.

    Pedestrians and cyclists may signal their presence on the road with the help of their own Bluetooth devices. The messages picked up by passing vehicles can be relayed using V2V communications over WAVE to extend the range of the warnings. Roadside beacons using Bluetooth technology can pass on information about local points of interest - and this can be provide to passengers who can subsequently look up more details on the Internet using the vehicle's built-in Wi-Fi hotspot.

    连接技术将驱动未来汽车的不断升级

    By Avinash Ghirnikar, Director of Technical Marketing of Connectivity Business Group, Marvell

    Without the ability to download and program devices quickly, the car could potentially become unusable for hours at a time.

    The same Ethernet backbone is proving just as essential for day-to-day use. The network provides high resolution, real-time data from cameras, LiDAR, radar, tire pressure monitors and various other sensors fitted around the body, each of which is likely to have their own dedicated microprocessor. The result is a high performance computer based on distributed intelligence.

    The same wireless communication networks that provide the over-the-air updates can relay real-time information on traffic patterns in the vicinity, weather data, disruptions due to accidents and many other pieces of data that the onboard computers can then use to plan the journey and make it safer.

    If the lights send out signals on their stop-go cycle approaching vehicles can use them to determine whether it is better to decelerate and arrive just in time for them to turn green instead of braking all the way to a stop. Sensors at the junction can also warn of hazards that the car then flags up to the driver. When the vehicle is able to run autonomously, it can take care of such actions itself. Similarly, cars can report to each other when they are planning to change lanes in order to leave the freeway, or when they see a slow-moving vehicle ahead and need to decelerate. The result is considerably smoother braking patterns that avoid the logjam effect we so often see on today's crowded roads.

    As many computations can be offloaded to servers in the cloud, the key to unlocking advanced functionality is not wholly dependent on what is present in the car itself. The fundamental requirement is access to an effective means of communications, and that is available right now through high speed Ethernet within the vehicle plus Wi-Fi and V2X-compatible wireless for transfers going beyond the chassis. Both can be supplied so that they are compliant with the AEC-Q100 automotive standard - thus ensuring quality and reliability. With those tools in place, we don't need to see all the way ahead to the future.

    合理精简以太网

    作者:Marvell 公司资深架构师 George Hervey

    Implementation of cloud infrastructure is occurring at a phenomenal rate, outpacing Moore's Law.

    More and more switches are required, thereby increasing capital costs, as well as management complexity. To tackle the rising expense issues, network disaggregation has become an increasingly popular approach. By separating the switch hardware from the software that runs on it, vendor lock-in is reduced or even eliminated.

    The number of managed switches basically stays the same.

    Network Disaggregation 

    Almost every application we use today, whether at home or in the work environment, connects to the cloud in some way. Our email providers, mobile apps, company websites, virtualized desktops and servers, all run on servers in the cloud. 

    As demand increases, Moore's law has struggled to keep up. Scaling data centers today involves scaling out - buying more compute and storage capacity, and subsequently investing in the networking to connect it all.

    Buying a switch, router or firewall from one vendor would require you to run their software on it as well. Larger cloud service providers saw an opportunity. These players often had no shortage of skilled software engineers.

    802.1BR 

    Today's cloud data centers rely on a layered architecture, often in a fat-tree or leaf-spine structural arrangement. Rows of racks, each with top-of-rack (ToR) switches, are then connected to upstream switches on the network spine. The ToR switches are, in fact, performing simple aggregation of network traffic. Using relatively complex, energy consuming switches for this task results in a significant capital expense, as well as management costs and no shortage of headaches. 

    By replacing ToR switches with port extenders, port connectivity is extended directly from the rack to the upstream.

    The Next Step in Network Disaggregation 

    Though many of the port extenders on the market today fulfill 802.1BR functionality, they do so using legacy components. Instead of being optimized for 802.1BR itself, they rely on traditional switches. This, as a consequence impacts upon the potential cost and power benefits that the new architecture offers. 

    Designed from the ground up for 802.1BR, Marvell's Passive Intelligent Port Extender (PIPE) offering is specifically optimized for this architecture. PIPE is interoperable with 802.1BR compliant upstream bridge switches from all the industry’s leading OEMs. It enables fan-less, cost efficient port extenders to be deployed, which thereby provide upfront savings as well as ongoing operational savings for cloud data centers.

    802.1BR's port extender architecture is bringing about the second wave, where ports are decoupled from the switches which manage them.

    延长基于 3.2T 交换机架构设备的生命周期

    By Yaron Zimmerman, Senior Staff Product Line Manager, Marvell and Yaniv Kopelman, Networking and Connectivity CTO, Marvell

    While network demands have increased, Moore's law (which effectively defines the semiconductor industry) has not been able to keep up. Instead of scaling at the silicon level, data centers have had to scale out. This has come at a cost though, with ever increasing capital, operational expenditure and greater latency all resulting. Facing this challenging environment, a different approach is going to have to be taken. In order to accommodate current expectations economically, while still also having the capacity for future growth, data centers (as we will see) need to move towards a modularized approach. switching-blogpost Scaling out the datacenter 

    Data centers are destined to have to contend with demands for substantially heightened network capacity - as a greater number of services, plus more data storage, start migrating to the cloud.

    In turn these are consuming more power - which impacts on the overall power budget and means that less power is available for the data center servers. Not only does this lead to power being unnecessarily wasted, in addition it will push the associated thermal management costs and the overall Opex upwards. As these data centers scale out to meet demand, they're often having to add more complex hierarchical structures to their architecture as well - thereby increasing latencies for both north-south and east-west traffic in the process. 

    We used to enjoy cost reductions as process sizes decreased from 90 nm, to 65 nm, to 40 nm. That is no longer strictly true however. As we see process sizes go down from 28 nm node sizes, yields are decreasing and prices are consequently going up. To address the problems of cloud-scale data centers, traditional methods will not be applicable.

    PIPEs and Bridges 

    Today's data centers often run on a multi-tiered leaf and spine hierarchy. Racks with ToR switches connect to the network spine switches. These, in turn, connect to core switches, which subsequently connect to the Internet.

    By following a modularized approach, it is possible to remove the ToR switches and replace them with simple IO devices - port extenders specifically. This effectively extends the IO ports of the spine switch all the way down to the ToR. What results is a passive ToR that is unmanaged. It simply passes the packets to the spine switch.

    The spine switch now acts as the controlling bridge. It is able to manage the layer which was previously taken care of by the ToR switch. This means that, through such an arrangement, it is possible to disaggregate the IO ports of the network that were previously located at the ToR switch, from the logic at the spine switch which manages them. This innovative modularized approach is being facilitated by the increasing number of Port Extenders and Control Bridges now being made available from Marvell that are compatible with the IEEE 802.1BR bridge port extension standard. 

    Solving Data Center Scaling Challenges 

    Port extenders solve the latency by flattening the hierarchy. Instead of having conventional ‘leaf’ and ‘spine’ tiers, the port extender acts to simply extend the IO ports of the spine switch to the ToR. Each server in the rack has a near-direct connection to the managing switch.

    The passive port extender is a greatly simplified device compared to a managed switch. This means lower up-front costs as well as lower power consumption and a simpler network management scheme are all derived.

    更好地利用原有的基础设施

    By Ron Cates

    The flexibility offered by wireless networking is revolutionizing the enterprise space. High-speed Wi-Fi®, provided by standards such as IEEE 802.11ac and 802.11ax, makes it possible to deliver next-generation services and applications to users in the office, no matter where they are working. However, the higher wireless speeds involved are putting pressure on the cabling infrastructure that supports the Wi-Fi access points around an office environment. The 1 Gbit/s Ethernet was more than adequate for older wireless standards and applications. Now, with greater reliance on the new generation of Wi-Fi access points and their higher uplink rate speeds, the older infrastructure is starting to show strain. At the same time, in the server room itself, demand for high-speed storage and faster virtualized servers is placing pressure on the performance levels offered by the core Ethernet cabling that connects these systems together and to the wider enterprise infrastructure. One option is to upgrade to a 10 Gbit/s Ethernet infrastructure. But this is a migration that can be prohibitively expensive. The Cat 5e cabling that exists in many office and industrial environments is not designed to cope with such elevated speeds. To make use of 10 Gbit/s equipment, that old cabling needs to come out and be replaced by a new copper infrastructure based on Cat 6a standards. Cat 6a cabling can support 10 Gbit/s Ethernet at the full range of 100 meters, and you would be lucky to run 10 Gbit/s at half that distance over a Cat 5e cable. In contrast to data-center environments that are designed to cope easily with both server and networking infrastructure upgrades, enterprise cabling lying in ducts, in ceilings and below floors is hard to reach and swap out. This is especially true if you want to keep the business running while the switchover takes place. Help is at hand with the emergence of the IEEE 802.3bz™ and NBASE-T® set of standards and the transceiver technology that goes with them. 802.3bz and NBASE-T make it possible to transmit at speeds of 2.5 Gbit/s or 5 Gbit/s across conventional Cat 5e or Cat 6 at distances up to the full 100 meters. The transceiver technology leverages advances in digital signal processing (DSP) to make these higher speeds possible without demanding a change in the cabling infrastructure. The NBASE-T technology, a companion to the IEEE 802.3bz standard, incorporates novel features such as downshift, which responds dynamically to interference from other sources in the cable bundle. The result is lower speed. But the downshift technology has the advantage that it does not cut off communication unexpectedly, providing time to diagnose the problem interferer in the bundle and perhaps reroute it to sit alongside less sensitive cables that may carry lower-speed signals. This is where the new generation of high-density transceivers come in. There are now transceivers coming onto the market that support data rates all the way from legacy 10 Mbit/s Ethernet up to the full 5 Gbit/s of 802.3bz/NBASE-T - and will auto-negotiate the most appropriate data rate with the downstream device. This makes it easy for enterprise users to upgrade the routers and switches that support their core network without demanding upgrades to all the client devices. Further features, such as Virtual Cable Tester® functionality, makes it easier to diagnose faults in the cabling infrastructure without resorting to the use of specialized network instrumentation. Transceivers and PHYs designed for switches can now support eight 802.3bz/NBASE-T ports in one chip, thanks to the integration made possible by leading-edge processes. These transceivers are designed not only to be more cost-effective, they also consume far less power and PCB real estate than PHYs that were designed for 10 Gbit/s networks. This means they present a much more optimized solution with numerous benefits from a financial, thermal and a logistical perspective. The result is a networking standard that meshes well with the needs of modern enterprise networks - and lets that network and the equipment evolve at its own pace.

    Autonomous Vehicles and Digital Features Make the Car of the Future a “Data Center on Wheels"

    By Donna

      The wireless, connectivity, storage and security technologies needed for the internal and external vehicle communications in cars today and in the future, leverage technologies used in a data center—in fact, you could say the automobile is becoming—a Data Center on Wheels. Here are some interesting data points supporting the evolution of the Data Center on Wheels:
    • The National Highway Traffic Safety Administration (NHTSA) mandates that by May 2018, all new cars in the U.S. to have backup cameras. The agency reports that half of all new vehicles sold today already have backup cameras, showing widespread acceptance even without the NHTSA mandate.
    • Some luxury brands provide panoramic 360-degree surround views using multiple cameras. NVIDIA, which made its claim to fame in graphics processing chips for computers and video games, is a leading provider in the backup and surround view digital platforms, translating its digital expertise into the hottest of new vehicle trends. At the latest 2017 International CES, NVIDIA showcased its latest NVIDIA PX2, an Artificial Intelligence (AI) Car Computer for Self-Driving Vehicles, which enables automakers and their tier 1 suppliers to accelerate production of automated and autonomous vehicles.
    • According to an Intel presentation at CES reported in Network World, just one autonomous car will use 4,000GB (or 4 Terabytes) of data per day.
    • A January study by Strategy Analytics reported that by 2020, new cars are expected to have approximately 1,000 chips per vehicle.
    Advanced Driver Assist Systems (ADAS), In-Vehicle Infotainment (IVI), autonomous vehicles—will rely on digital information streamed internally within the vehicle and externally from the vehicle to other vehicles or third-party services via chips, sensors, network and wireless connectivity.  All of this data will need to be processed, stored or transmitted seamlessly and securely, because a LoJack® isn’t necessarily going to help with a car hack. This is why auto makers are turning to the high tech and semiconductor industries to support the move to more digitized, automated cars. Semiconductor leaders in wireless, connectivity, storage, and networking are all being tapped to design and manage the Data Center on Wheels.  For example, Marvell recently announced the first automotive grade system-on-chip (SoC) that integrates the latest Wi-Fi, Bluetooth, vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) capabilities.  Another technology product being offered for automotive use is the InnoDisk SATA 3ME4 Solid-State Drive (SSD) series. Originally designed for industrial systems integrations, these storage drives can withstand the varied temperature ranges of a car, as well as shock and vibration under rugged conditions. Both of these products integrate state-of-the-art encryption to not only keep and store information needed for data-driven vehicles, but keep that information secure from unwanted intrusion. Marvell and others are working to form standards and adapt secure digital solutions in wireless, connectivity, networking and storage specifically for the automobile, which is even more paramount in self-driving vehicles.

    Marvell 为开创性的新开源 NAS 解决方案提供一臂之力

    作者:Maen Suleiman,Marvell 软件产品线高级经理

    As a result each of us is generating, downloading and transferring larger amounts of data-heavy content than would have been even conceivable a relatively short while in the past. For example, market research firm InfoTrends has estimated that consumers worldwide will be responsible for taking over 1.2 trillion new photos during 2017 (that is more than double the figure from 5 years ago). Furthermore, there are certainly no indications that the dynamics that are driving this will weaken and everything will start to slow down.

    If individuals are to keep on amassing personal data at current rates, then it is clear that they will need access to a new form of flexible storage solution that is up to the job. In a report compiled by industry analysts at Technavio, the global consumer network attached storage (NAS) market
    is predicted to grow accordingly - witnessing an impressive 11% compound annual growth between now and the end of this decade. 

    Start-up company Kobol has recently initiated a crowdfunding campaign to garner financial backing for its Helios4 offering. The first of its kind - this is an open source, open hardware NAS solution that will allow the storing and sharing of music, photos and movies through connection to the user’s home network. It presents consumers with a secure, flexible and rapidly accessible data storage reserve with a capacity of up to 40 TeraBytes (which equates to around 700,000 hours of music, 20,000 hours of movies or 12 million photos). 

    Built-in RAID redundancy is included in order for ongoing reliability to be assured. This means that even if one of the 4 hard drives (each delivering 10 TeraBytes) were to crash, the user’s content would remain safely stored, as the data is mirrored onto another of its drives.

      图 1: Schematic showing the interface structure of Helios4 powered by ARMADA 388 SoC 

     

    图 2:

    Otherwise, for those with less engineering experience it comes as a straightforward to use out-of-the-box solution.

    At the heart of the Helios4’s design is a sophisticated ARMADA 388 32-bit ARM-based system-on-chip (SoC) from Marvell, which combines high performance benchmarks with power frugal operation. Based on 28nm node, low power semiconductor technology, its dual-core ARM Cortex-A9 processing resource is capable of running at speeds of up to 1.8 GHz. USB 3.0 SuperSpeed and SATA 3.0 ports are included so that elevated connectivity levels can be supported. Cryptographic mechanisms are also integrated to maintain superior system security. 

    By clicking on the following link you can learn more about the Helios4 Kickstarter campaign. For those interested in getting involved, the deadline to make a contribution is 19th June.

    社区开发板允许在数据中心、网络和存储生态系统中轻松采用 ARM 64 位性能

    作者:Maen Suleiman,Marvell 软件产品线高级经理

    Marvell MACCHIATObin community board is first-of-its-kind, high-end ARM 64-bit networking and storage community board 

    The industry is answering that call through technologies and concepts such as software defined networking (SDN), network function virtualization (NFV) and distributed storage. Making the most of these technologies and unleashing the potential of the new applications requires a collaborative approach.

    A key way to foster such collaboration is through open-source ecosystems. The rise of Linux has demonstrated the effectiveness of such ecosystems and has helped steer the industry towards adopting open-source solutions. AT&T Runs Open Source White Box Switch in its Live NetworkSnapRoute and Dell EMC to Help Advance Linux Foundation's OpenSwitch ProjectNokia launches AirFrame Data Center for the Open Platform NFV community

    Communities have come together through Linux to provide additional value for the ecosystem. One example is the Linux Foundation Organization which currently sponsors more than 50 open source projects. Its activities cover various parts of the industry from IoT ( IoTivity , EdgeX Foundry ) to full NFV solutions, such as the Open Platform for NFV (OPNFV). This is something that would have been hard to conceive even a couple of years ago without the wide market acceptance of open-source communities and solutions. 

    Although there are numerous important open-source software projects for data-center applications, the hardware on which to run them and evaluate solutions has been in short supply. There are many ARM® development boards that have been developed and manufactured, but they primarily focus on simple applications. 

    All these open source software ecosystems require a development platform that can provide a high-performance central processing unit (CPU), high-speed network connectivity and large memory support. But they also need to be accessible and affordable to ARM developers. Marvell MACCHIATObin® is the first ARM 64-bit community platform for open-source software communities that provides solutions for, among others, SDN, NFV and Distributed Storage. A high-performance ARM 64-bit community platform                                   A high-performance ARM 64-bit community platform 

    It is based on the Marvell hyperscale SBSA-compliant ARMADA® 8040 system on chip (SoC) that features four high-performance Cortex®-A72 ARM 64-bit CPUs.

    
					CPU

    SolidRun (https://www.solid-run.com/) started shipping the Marvell MACCHIATObin community board in March 2017, providing an early access of the hardware to open-source communities. 

    The Marvell MACCHIATObin community board is easy to deploy. It uses the compact mini-ITX form factor, enabling developers to purchase one of the many cases based on the popular standard mini-ITX case to meet their requirements. The ARMADA 8040 SoC itself is SBSA-compliant (http://infocenter.arm.com/help/topic/com.arm.doc.den0029/) to offer unified extensible firmware interface (UEFI) support. 

    In addition, the SoC provides two security engines that can perform full IPSEC, DTL and other protocol-offload functions at 10G rates.

    For hardware expansion, the Marvell MACCHIATObin community board provides one PCIex4 3.0 slot and a USB3.0 host connector. For non-volatile storage, options include a built-in eMMC device and a micro-SD card connector. Mass storage is available through three SATA 3.0 connectors. For debug, developers can access the board’s processors through a choice of a virtual UART running over the microUSB connector, 20-pin connector for JTAG access or two UART headers. MACCHIATObin Specification

    Open source software enables advanced applications 

    The Marvell MACCHIATObin community board comes with rich open source software that includes ARM Trusted Firmware (ATF)U-BootUEFILinux KernelYoctoOpenWrtOpenDataPlane (ODP) , Data Plane Development Kit (DPDK)netmap and others; many of the Marvell MACCHIATObin open source software core components are available at: https://github.com/orgs/MarvellEmbeddedProcessors/

    To provide the Marvell MACCHIATObin community board with ready-made support for the open-source platforms used at the edge and data centers for SDN, NFV and similar applications, standard operating systems like Suse Linux EnterpriseCentOSUbuntu and others should boot and run seamlessly on the Marvell MACCHIATObin community board. 

    As the ARMADA 8040 SoC is SBSA compliant and supports UEFI with ACPI, along with Marvell’s upstreaming of Linux kernel support, standard operating systems can be enabled on the Marvell MACCHIATObin community board without the need of special porting. 

    On top of this core software, a wide variety of ecosystem applications needed for the data center and edge applications can be assembled. 

    For example, using the ARMADA 8040 SoC high-speed networking and security engine will enable the kernel netdev community to develop and maintain features such as XDP or other kernel network features on ARM 64-bit platforms. The ARMADA 8040 SoC security engine will enable many other Linux kernel open-source communities to implement new offloads. 

    Thanks to the virtualization support available on the ARM Cortex A72 processors, virtualization technology projects such as KVM and XEN can be enabled on the platform; container technologies like LXC  and Docker can also be enabled to maximize data center flexibility and enable a virtual CPE ecosystem where the Marvell MACCHIATObin community board can be used to develop edge applications on a 64-bit ARM platform. 

    In addition to the mainline Linux kernel, Marvell is upstreaming U-Boot and UEFI, and is set to upstream and open the Marvell MACCHIATObin ODP and DPDK support. This makes the Marvell MACCHIATObin board an ideal community platform for both communities, and will open the door to related communities who have based their ecosystems on ODP or DPDK. These may be user-space network-stack communities such as OpenFastPath and FD.io or virtual switching technologies that can make use of both the ARMADA 8040 SoC virtualization support and networking capabilities such as Open vSwitch (OVS) or Vector Packet Processing (VPP).  Similar to ODP and DPDK, Marvell MACCHIATObin netmap support can enable VALE virtual switching technology or security ecosystem such as pfsense.

    CPU2

    Thanks to its hardware features and upstreamed software support, the Marvell MACCHIATObin community board is not limited to data center SDN and NFV applications. It is highly suited as a development platform for network and security products and applications such as network routers, security appliances, IoT gateways, industrial computing, home customer-provided equipment (CPE) platforms and wireless backhaul controllers; a new level of scalable and modular solutions can be further achieved when combining the Marvell MACCHIATObin community board with Marvell switches and PHY products. 

    Summary 

    The board supports a rich software ecosystem and has made available high-performance, high-speed networking ARM 64-bit community platforms at a price that is affordable for the majority of ARM developers, software vendors and other interested companies.

    无线办公的重大推进

    作者:Yaron Zimmerman,Marvell 公司高级职员产品线经理

    现代企业办公环境正在逐步地向大量的无线连接方式转变,从而给员工提供更大的工作便利,以及实现更便捷的管理。 有了无线技术所提供的便利,办公人员将不再受限于哪里有电缆/端口,因而具有更高的可移动性。 It will mean that they can remain constantly connected and their work activities won’t be hindered - whether they are at their desk, in a meeting or even in the cafeteria. This will make enterprises much better aligned with our modern working culture - where hot desking and bring your own device (BYOD) are becoming increasingly commonplace. 

    这一趋势不断加速的主要原因是 802.11ac Wave 2 Wi-Fi 技术的出现。 由于这种技术可以实现千兆位数据速率(从而支持视频流媒体、更快的下载速度以及更高质量的视频会议等等),因而它具有很大的吸引力。 In addition, this protocol offers extended range and greater bandwidth through multi-user MIMO operation - so that a larger number of users can be supported simultaneously. 特定数量的用户需要的接入点更少,这对企业来说非常具有优势。Pipe

    图1是一个针对企业/园区办公室平面图的例子,其中有大量的隔间,还有一些会议室。 虽然具体情况有所不同,但一般来说,企业/园区的占地面积可能在 20,000 至 45,000 平方英尺之间。 一个 802.11ac 接入点可以覆盖 3,000 到 4,000 平方英尺的面积,因而一个无线办公室需要总共约 8 到 12 个接入点才能充分覆盖。 如果是满足日常的语音和数据需求,这个密度应该可以接受, 而支持这些接入点的将是一个高容量的有线主干网络。

    企业/园区主干网正在越来越多地采用基于 25 千兆以太网技术的基础设施,而不是传统的 10 千兆以太网。 在未来 2-3 年中,随着相关光学器件的价格变得更加实惠,预计 25 千兆以太网技术将会在新建办公楼得到更广泛地采用。 显然,企业希望利用 802.11ac 技术所提供的更高性能,但是他们在这样做时,也必须遵守严格的预算限制。 随着主干网数据容量的提高,其下层的分层网络结构由于包含各种中间交换机技术,其复杂性也会相应上升。 这些都是根据传统理论得出的结论。

    在开始实施 25 千兆以太网技术/ 802.11ac 之前,企业必须充分认识到这种技术带来的问题。 除了刚刚提到的与硬件安装相关的初始投资,还必须考虑持续运营成本。 By aggregating the access points into a port extender that is then connecting directly to the 25 Gigabit Ethernet backbone instead towards a central control bridge switch, it is possible to significantly simplify the hierarchical structure - effectively eliminating a layer of unneeded complexity from the system. 

    Marvell 公司正在通过采用一种被动智能端口扩展 (PIPE) 的技术来实现上述目的。 这种产品是市场上特有的技术,目前可用的其他端口扩展器并不是为了这个目的而设计,因此在性能、价格和功率方面都没有进行优化。 PIPE is, in contrast, an optimized solution that is able to fully leverage the IEEE 802.1BR bridge port extension standard - dispensing with the need for expensive intermediary switches between the control bridge and the access point level and reducing the roll-out costs as a result. 由于不再将多个 802.11ac 接入点聚合到 10 千兆以太网交换机上,吞吐量因此可得到大幅提升。 同时因为需要管理的网络单元减少,持续运营成本也随之降低。

    PIPE means that enterprises can future proof their office data communication infrastructure - starting with 10 Gigabit Ethernet, then upgrading to a 25 Gigabit Ethernet when it is needed. 它所包含的端口数量能够与企业/校园需要的接入点数量相匹配,以满足员工的无线连接需求。 它支持双归属 (dual homing) 功能,从而通过系统冗余来确保更高的服务可靠性和灵活性。 In addition, supporting Power-over-Ethernet (PoE), allows access points to connect to both a power supply and the data network through a single cable - further facilitating the deployment process.

    自动驾驶汽车面临的挑战:无人驾驶汽车的以太网带宽问题如何攻克?

    By Nick Ilyadis

    Each of these technologies stream information, or data, within the car, and as automotive technology evolves, more and more features will be added. But when it comes to autonomous vehicles, the amount of technology and data streams coming into the car to be processed increases exponentially. Autonomous vehicles gather multiple streams of information/data from sensors, radar, radios, IR sensors and cameras. This goes beyond the current Advanced Driver Assist Systems (ADAS) or In-Vehicle Infotainment (IVI). The autonomous car will be acutely aware of its surroundings running sophisticated algorithms that will make decisions in order to drive the vehicle. However, self-driving cars will also be processing vehicle-to-vehicle communications, as well as connecting to a number of external devices that will be installed in the highway of the future, as automotive communication infrastructures develop. Start the car; drive; turn; red light, stop; - PEDESTRIAN - BRAKE!

     Add to the driving functions the simultaneous infotainment streams for each passenger, vehicle Internet capabilities, etc. and the current 100 megabits-per-second (mbps) 100BASE-T1 Ethernet bandwidth used in automotive, is quickly strained. This is paving the way (pun intended) for 1000BASE-T1 Gigabit Ethernet (GbE) for automotive networks. Ethernet has long been the economical volume workhorse with millions of miles of cabling in buildings the world over. Therefore, the IEEE 802.3 Ethernet Working Group has endorsed iGbE as the next network bandwidth standard in automotive.

    From Car-jacking to Car-hacking—Security Critical 

     

    This is why companies like Marvell, have taken a leadership role with organizations like IEEE to help create open standards, such as GbE for automotive, to keep moving automotive technologies forward. (See IEEE 2014 Automotive Day presentation by Alex Tan on the Benefits of Designing 1000BASE-T1 into Automotive Architectures http://standards.ieee.org/events/automotive/2014/02_Designing_1000BASE-T1_Into_Automotive_Architectures.pdf.)

    Technology to Drive Next-Generation Automotive Networking

    Marvell’s Automotive Ethernet Networking technology is capable of taking what used to be the separate domains of the car — infotainment, driver assist, body electronics and control — and connecting them together to provide a high-bandwidth standards-based data backbone for the vehicle. For example, the Marvell 88Q2112 is the industry’s first 1000BASE-T1 automotive Ethernet PHY transceiver compliant with the IEEE 802.3bp 1000BASE-T1 standard. The Marvell 88Q2112 supports the market’s highest in-vehicle connectivity bandwidth and is designed to meet the rigorous EMI requirements of an automotive system. The 1000BASE-T1 standard allows high-speed and bi-directional data traffic and in-vehicle uncompressed 720p30 camera video for multiple HD video streams, including 4K resolution, all over a lightweight, low-cost single pair cable. The Marvell 88Q1010 low-power PHY device supports 100BASE-T1 and compressed 1080p60 video for infotainment, data transport and camera systems.  And finally to round out its automotive networking solutions, Marvell also offers a series of 7-port Ethernet switches.

    11ac Wave 2 和 11ax 在 Wi-Fi 部署中的挑战: 如何经济高效地升级到 2.5GBASE-T 和 5GBASE-T

    By Nick Ilyadis

    IEEE has also noted that in the past two decades, the IEEE 802.11 wireless local area networks (WLANs) have also experienced tremendous growth with the proliferation of IEEE 802.11 devices, as a major Internet access for mobile computing. Therefore, the IEEE 802.11ax specification is under development as well.  Giving equal time to Wikipedia, its definition of 802.11ax is: a type of WLAN designed to improve overall spectral efficiency in dense deployment scenarios, with a predicted top speed of around 10 Gbps. It works in 2.4GHz or 5GHz and in addition to MIMO and MU-MIMO, it introduces Orthogonal Frequency-Division Multiple Access (OFDMA) technique to improve spectral efficiency and also higher order 1024 Quadrature Amplitude Modulation (QAM) modulation support for better throughputs. Though the nominal data rate is just 37 percent higher compared to 802.11ac, the new amendment will allow a 4X increase of user throughput. This new specification is due to be publicly released in 2019.

    Faster “Cats” Cat 5, 5e, 6, 6e and on

    And yes, even cabling is moving up to keep up. Differences between CAT5, CAT5e, CAT6 and CAT6e Cables for specifics), but suffice it to say, each iteration is capable of moving more data faster, starting with the ubiquitous Cat 5 at 100Mbps at 100MHz over 100 meters of cabling to Cat 6e reaching 10,000 Mbps at 500MHz over 100 meters. Cat 7 can operate at 600MHz over 100 meters, with more “Cats” on the way. All of this of course, is to keep up with streaming, communications, mega data or anything else being thrown at the network.

    How to Keep Up Cost-Effectively with 2.5BASE-T and 5BASE-T

    This is where Marvell steps in with a whole solution. Marvell’s products, including the Avastar wireless products, Alaska PHYs and Prestera switches, provide an optimized solution that will help support up to 2.5 and 5.0 Gbps speeds, using existing cabling. For example, the Marvell Avastar 88W8997 wireless processor was the industry's first 28nm, 11ac (wave-2), 2x2 MU-MIMO combo with full support for Bluetooth 4.2, and future BT5.0. To address switching, Marvell created the Marvell® Prestera® DX family of packet processors, which enables secure, high-density and intelligent 10GbE/2.5GbE/1GbE switching solutions at the access/edge and aggregation layers of Campus, Industrial, Small Medium Business (SMB) and Service Provider networks. And finally, the Marvell Alaska family of Ethernet transceivers are PHY devices which feature the industry's lowest power, highest performance and smallest form factor.

    These transceivers help optimize form factors, as well as multiple port and cable options, with efficient power consumption and simple plug-and-play functionality to offer the most advanced and complete PHY products to the broadband market to support 2.5G and 5G data rate over Cat5e and Cat6 cables.

    手机的出现如何点燃当今的数据需求增长

    作者:Sander Arts,Marvell 市场营销代理副总裁

    1973 年 4 月 3 日,也就是大约 44 年以前,一位名叫 Martin Cooper 的工程师沿着曼哈顿的街道往前走,手里拿着个像砖头一样的设备,拨通了有史以来的第一次移动通话。 世界上第一部移动设备重量达到令人乍舌的 2.5 磅,高 11 英寸,突出特点是只有一条线路、只能发送短信的 LED 显示屏。 

    版权: 维基百科

    从那以后发生了很多变化。 电话变得更小、更快,也更智能,以四十年前人们无法想象的速度更新换代。 今天,打电话只是我们期望移动设备承担的众多功能之一,此外它还要能上网浏览、观看视频、查找方位、参与社交,还有其他各种功能。 所有这些活动都要求数据的快速移动和存储,与最初的 PC 更加相似,而非 Cooper 的 2.5 磅原型机。 而且这还只是个开始,数据需求的增长比移动技术的更新换代更加迅速。

    数据需求: 超越无限!

    现今的消费者可以使用各种各样的设备,几乎瞬时读取来自全世界的内容,这些设备包括智能手机、平板电脑、汽车,甚至是家用电器。 不管是大型活动,比如超级碗 LI,还是普通的一天,数据使用量都在迅猛增长,人们跟朋友、家人和世界各地的陌生人交流,分享想法、上传照片、观看视频、玩游戏,还有很多其他的活动。

    根据 Domo 所做的一项研究,在美国,消费者每分钟要使用超过 180 万兆字节无线数据。 在最近的 2017 美国 OCP 峰会上,Facebook 宣称每天会有 9500 万份照片和视频通过 Instagram 发布,而这还只是单独一个应用程序。随着我们的世界变得更加智能、连接程度更高,数据需求只会继续不断增长。

    端口扩展器技术让网络交换焕然一新

    作者:Marvell 公司资深架构师 George Hervey

    PIPE-Data-Center_V21-sized Our lives are increasingly dependent on cloud-based computing and storage infrastructure. It is no surprise therefore that the demands on such infrastructure are growing at an alarming rate, especially as the trends of big data and the internet of things start to make their impact. With an increasing number of applications and users, the annual growth rate is believed to be 30x per annum, and even up to 100x in some cases. Such growth leaves Moore’s law and new chip developments unable to keep up with the needs of the computing and network infrastructure. These factors are making the data and communication network providers invest in multiple parallel computing and storage resources as a way of scaling to meet demands.

    Within a data center a classic approach to networking is a hierarchical one, with an individual rack using a leaf switch – also termed a top-of-rack or ToR switch – to connect within the rack, a spine switch for a series of racks, and a core switch for the whole center. And, like the servers and storage appliances themselves, these switches all need to be managed. In the recent past there have usually been one or two vendors of data center network switches and the associated management control software, but things are changing fast. Most of the leading cloud service providers, with their significant buying power and technical skills, recognised that they could save substantial cost by designing and building their own network equipment. Many in the data center industry saw this as the first step in disaggregating the network hardware and the management software controlling it. With no shortage of software engineers, the cloud providers took the management software development in-house while outsourcing the hardware design.

    The concept rests on the belief that there are many nodes in the network that don’t need the extensive management capabilities most switches have. Essentially this introduces a parent/child relationship, with the controlling switch, the parent, being the managed switch and the child, the port extender, being fed from it. This port extender approach was ratified into the networking standard 802.1BR in 2012, and every network switch built today complies with this standard.

    Look under the lid of a port extender and you’ll find the same switch chip being used as in the parent bridge. We have moved forward, sort of. Without a chip specifically designed as a port extender switch vendors have continued to use their standard chips sets, without realising potential cost and power savings. However, the truly modular approach to network switching has taken a leap forward with the launch of Marvell’s 802.1BR compliant port extender IC termed PIPE – passive intelligent port extender, enabling interoperability with a controlling bridge switch from any of the industry’s leading OEMs. It also offers attractive cost and power consumption benefits, something that took the shine off the initial interest in port extender technology. Seen as the second stage of network disaggregation, this approach effectively leads to decoupling the port connectivity from the processing power in the parent switch, creating a far more modular approach to networking.

    Marvell’s Prestera® PIPE family targets data centers operating at 10GbE and 25GbE speeds that are challenged to achieve lower CAPEX and OPEX costs as the need for bandwidth increases. The Prestera PIPE family will facilitate the deployment of top-of-rack switches at half the cost and power consumption of a traditional Ethernet switch. The PIPE approach also includes a fast fail over and resiliency function, essential for providing continuity and high availability to critical infrastructure.

    NVMe 控制器突破数据中心传统磁介质的局限性具备高速且低成本优势的 NVMe SSD 共享存储已进入第二代

    作者:Nick Ilyadis,Marvell 产品线技术副总裁

    Marvell 在 OCP 峰会上初次推出第二代 NVM Express SSD 控制器 88SS1092  

    88SS1092_C-sized 数据中心 SSD: NVMe and Where We’ve Been 

    When solid-state drives (SSDs) were first introduced into the data center, the infrastructure mandated they work within the confines of the then current bus technology, such as Serial ATA (SATA) and Serial Attached SCSI (SAS), developed for rotational media. 即使非常快的 HDD 也比不上 SSD 的速度,其对应总线的吞吐能力也成为阻碍充分发挥 SSD 技术优势的一大瓶颈。 作为一种在网络,图形以及其他插入式设备上广泛应用的高带宽总线, PCIe 成为了可行的选择,但 PCIe 总线配合原本为 HDD 开发的存储协议(例如 AHCI)仍然无法有效发挥易失性存储介质的性能优势。 因此,NVM Express (NVMe) 行业工作组成立,创建一组为 PCIe 总线开发的标准化协议和命令,以便允许多条路径可以充分利用数据中心中 SSD 的优势。 The NVMe specification was designed from the ground up to deliver high-bandwidth and low-latency storage access for current and future NVM technologies. 

    NVMe 优化了命令发送和完成通路, 单个 I/O 队列中支持多达 64K 条命令。 此外,增加了许多企业功能支持,例如端到端数据保护(与 T10 DIF 和 DIX 标准兼容),增强错误报告和虚拟化功能。 总而言之,NVMe 作为一种可扩展的存储应用协议,旨在充分发挥 PCIe SSD 性能,从而更好的满足企业级、数据中心和消费级等各种场景的应用需求。

    SSD Network Fabrics 

    New NVMe controllers from companies like Marvell allowed the data center to share storage data to further maximize cost and performance efficiencies. 使用 SSD 建立存储集群,取代以往为每台服务器单独配置存储的方式,提高数据中心存储总容量。 此外,通过为其他服务器建立公共区传送数据,可以方便地访问共享数据。 因此,这些新计算模型使数据中心不仅能够充分优化 SSD 的高速性能,而且能够更经济地在整个数据中心部署 SSD,从而降低总体成本并简化维护。 针对负载较高的服务器,不用增加额外的 SSD,而是从存储池动态分配满足其需求。

    以下是这些网络结构工作原理的简单示例: 如果一个系统有 10 个服务器,每个服务器的 PCIe 总线上都有一个 SSD,那么可以通过每个 SSD 形成一个 SSD 组成的存储池群,它不仅提供了一种额外的存储手段,而且还提供了一种集中和共享数据访问的方法。 假设一台服务器的利用率只有 10%,而另一台服务器被超负荷使用,SSD 组成的存储池群将为超负荷的服务器提供更多的存储空间,而无需为其额外添加 SSD。 在这个例子中如果是数百台服务器,您会看到其成本、维护和性能效率是非常高的。

    Marvell 当初推出第一款 NVMe SSD 控制器,就是服务于这种新的数据中心存储架构。 该产品仅可支持四个 PCIe 3.0 通道,根据主机需要,可以配置为支持 4BG/S 和 2BG/S 两种带宽方式。 它使用 NVMe 高级命令处理实现了出类拔萃的 IOPS 性能。 为了充分利用 PCIe 总线带宽,Marvell 创新的 NVMe 设计通过大量的硬件辅助来增强 PCIe 链路数据的传送。 这有助于解决传统的主机控制瓶颈问题,发挥出闪存真正的性能。

    第二代 NVMe 控制器已经面市! 

    Marvell 第二代 NVMe SSD 控制器芯片 88SS1092 已推出,并已通过了内部测试和第三方操作系统/平台的兼容性测试。 因此,Marvell®88SS1092 已为用于增强下一代存储和数据中心系统做好准备,并在 2017 年 3 月举行的美国加州圣荷塞举行的开放计算项目 (OCP) 峰会上初次亮相。

    The Marvell 88SS1092 is Marvell's second-generation NVMe SSD controller capable of PCIe 3.0 X 4 end points to provide full 4GB/s interface to the host and help remove performance bottlenecks. While the new controller advances a solid-state storage system to a more fully flash-optimized architecture for greater performance, it also includes Marvell's third-generation error-correcting, low-density parity check (LDPC) technology for the additional reliability enhancement, endurance boost and TLC NAND device support on top of MLC NAND. 

    今天,NVMe SSD 共享存储的速度和成本优势不仅成为了现实,而且已经发展到了第二代。 网络模式已经发生了变化。 通过使用 NVMe 协议充分发挥 SSD 的全部性能,突破传统磁介质的限制,建立全新的架构。 SSD 性能还可以进一步提高,而 SSD 组成的存储池群和新的网络架构支持实现存储池和共享数据访问。 在当今的数据中心,随着新的控制器和技术帮助优化了 SSD 技术的性能和成本效率,NVMe 工作组的辛勤工作正在付诸实践。

    往事回顾: 圣克拉拉山谷如何用果树换芯片

    作者:Sander Arts,Marvell 市场营销代理副总裁

    在硅谷成为高科技和创新的同义词之前,它曾被称为“心灵之欢的峡谷”。 这片辽阔的土地因旧金山以南的大面积果园而颇具盛名,也将成为世界最具创新精神的科技企业未来的家园。 FlashbackFriday1 回顾这个区域的历史,会发觉它成为激发灵感、孕育文化的摇篮并不奇怪,有一天,开创未来的先进技术将从车库、大学宿舍,甚至厨房灶台应运而生,全盘改变人们的生活。 硅谷自身的历史开始于一间车库,两名斯坦福大学的毕业生 William Hewlett 和 David Packard 将在稍后的 1939 年创立 Hewlett-Packard 公司。 随后的十年间,企业家和科学家纷至沓来,在圣克拉拉山谷探索无线电、军事和电子技术,为未来打下坚实的基础,使其成为科技创新的温床。发源地 到 1953 年,有名的科技公司开始正式在圣克拉拉山谷占据一席之地,在斯坦福工业园购置地产,随后不久,该区域的一家半导体公司于 1956 年成立。 贯穿整个 1960 年代的是如火如荼的太空竞赛,整个国家都高度关注针对高级芯片 (silicon) 技术的强烈需求,而这个山谷开始逐渐成为国家高精尖技术发展的中心。 由于园区的芯片公司数量众多,而且人们对于半导体行业越来越重视,该区域最终正式命名为“硅谷”(Silicon Valley),于 1971 年在一系列 Electronic News 的报道中公开使用。

    此后的 30 年中,一些全世界富有开创性的科技公司将在硅谷成立。 Marvell 正式踏足该领域是在 1995 年,当时正值互联网泡沫中期。 自此之后,我们亲眼见证了科技图景如何在创新和企业家精神的推动下呈指数级成长。 自 1939 年开始萌芽的创业精神到 21 世纪一直持续迅速发展,激励我们继续前进、创新并不断挑战现有的技术。 在 Marvell,我们对未来芯片、数据和云技术的发展前景深信不疑,并期待能够参与其中,逐步成为硅谷下一代的企业家和思想家巨头。Marvell-campus

    全新的扩展范例:以太网端口扩展器

    作者:Michael Zimmerman,Marvell CSIBU 副总裁兼总经理

    Over the last three decades, Ethernet has grown to be the unifying communications infrastructure across all industries. More than 3M Ethernet ports are deployed daily across all speeds, from FE to 100GbE. In enterprise and carrier deployments, a combination of pizza boxes — utilizing stackable and high-density chassis-based switches — are used to address the growth in Ethernet. However, over the past several years, the Ethernet landscape has continued to change. With Ethernet deployment and innovation happening fastest in the data center, Ethernet switch architecture built for the data center dominates and forces adoption by the enterprise and carrier markets. This new paradigm shift has made architecture decisions in the data center critical and influential across all Ethernet markets. However, the data center deployment model is different.  

    How Data Centers are Different

    Ethernet-Extenders The ultimate goal is to pack as many Ethernet ports at the highest commercially available speed onto the Ethernet switch, and make it the most economical and power efficient. The end point connected to the ToR switch is the server NIC which is typically the highest available speed in the market (currently 10/25GbE moving to 25/50GbE). Today, 128 ports of 25GbE switches are in deployment, going to 64x 100GbE and beyond in the next few years. But while data centers are moving to higher port density and higher port speeds, and homogenous deployment, there is still a substantial market for lower speeds such as 10GbE that continues to be deployed and must be served economically. The innovation in data centers drives higher density and higher port speeds but many segments of the market still need a solution with lower port speeds with different densities. How can this problem be solved?  

    Bridging the Gap

    The IEEE standards codified the 802.1br port extender standard as the protocol needed to allow a fan-out of ports from an originating higher speed port. In essence, one high end, high port density switch can fan out hundreds or even thousands of lower speed ports. The high density switch is the control bridge, while the devices which fan out the lower speed ports are the port extenders.  

    Why Use Port Extenders

    In addition to re-packaging the data center switch as a control bridge, there are several unique advantages for using port extenders:

    Port extenders are only a fraction of the cost, power and board space of any other solution aimed for serving Ethernet ports.

    Port extenders have very little or no software. This simplified operational deployment results in the number of managed entities limited to only the high end control bridges.

    Port extenders communicate with any high-end switch, via standard protocol 802.1br. Additional options such as Marvell DSA, or programmable headers are possible.)

    Port extenders work well with any transition service: 100GbE to 10GbE ports, 400GbE to 25GbE ports, etc.

    Port extenders can operate in any downstream speed: 1GbE, 2.5GbE, 10GbE, 25GbE, etc.

    Port extenders can be oversubscribed or non-oversubscribed, which means the ratio of upstream bandwidth to downstream bandwidth can be programmable from 1:1 to 1:4 (depending on the application). This by itself can lower cost and power by a factor of 4x.

        Port-Extenders  

    Marvell Port Extenders

    Marvell has launched multiple purpose-built port extender products, which allow fan-out of 1GbE and 10GbE ports of 40GbE and 100GbE higher speed ports. Along with the silicon solution, software reference code is available and can be easily integrated to a control bridge. Marvell conducted interoperability tests with a variety of control bridge switches, including the leading switches in the market. The benchmarked design offers 2x cost reduction and 2x power savings.

    以太网达尔文主义: 适者生存(唯快不破)

    作者:Michael Zimmerman,Marvell CSIBU 副总裁兼总经理

    The most notable metric of Ethernet technology is the raw speed of communications. With the introduction of 100BASE-T, the massive 10BASE-T installed base was replaced, showing a clear Darwinism effect of the fittest (fastest) displacing the prior and older generation. However, when 1000BASE-T (GbE – Gigabit Ethernet) was introduced, contrary to industry experts’ predictions, it did not fully displace 100BASE-T, and the two speeds have co-existed for a long time (more than 10 years). In fact, 100BASE-T is still being deployed in many applications. The introduction — and slow ramp — of 10GBASE-T has not impacted the growth of GbE, and it is only recently that GbE ports began consistently growing year over year. This trend signaled a new evolution paradigm of Ethernet: the new doesn’t replace the old, and the co-existence of multi variants is the general rule. The introduction of 40GbE and 25GbE augmented the wide diversity of Ethernet speeds, and although 25GbE was rumored to displace 40GbE, it is expected that 40GbE ports will still be deployed over the next 10 years1. Ethernet-Diversity Hence, a new market reality evolved: there is less of a cannibalizing effect (i.e. newer speed cannibalizing the old), and more co-existence of multiple variants. This new diversity will require a set of solutions which allow effective support for multiple speed interconnect.

    能够经济地缩小到几个端口2

    Support of multiple Ethernet speeds

    The first products in the family are the Prestera® 98DX83xx 320G interconnect switch, and the Alaska® 88X5113 25G/40G Gearbox PHY. The 98DX83xx switch fans-out up to 32-ports of 10GbE or 8-ports of 40GbE, in economical 24x20mm package, with power of less than 0.5Watt/10G port. Interconnect1 The 88X5113 Gearbox converts a single port of 40GbE to 25GbE. The combination of the two devices creates unique connectivity configurations for a myriad of Ethernet speeds, and most importantly enables scale down to a few ports. While data center- scale 25GbE switches have been widely available for 64-ports, 128-ports (and beyond), a new underserved market segment evolved for a lower port count of 25GbE and 40GbE. Marvell has addressed this space with the new interconnect solution, allowing customers to configure any number of ports to different speeds, while keeping the power envelope to sub-20Watt, and a fraction of the  hardware/thermal footprint of comparable data center solutions. The optimal solution to serve low port count connectivity of 10GbE, 25GbE, and 40GbE is now well addressed by Marvell. Samples and development boards with SDK are ready, with the option of a complete package of application software.Interconnect2

    Marvell PHY,专为实现低延时工业以太网

    By Kaushik Mittra, Senior Product Marketing Manager, Ethernet PHY products, Connectivity, Storage and Infrastructure Business Unit, Marvell

    Part 1 of Two-Part Series

    Introducing the Marvell 88E1510P/1512P/1510Q Family of PHY Products

    Industrial networks present their own set of challenges, and Ethernet with its components are evolving again to address the needs of the factory floor. Connectivity hardware that can offer low-latency, enhanced electrostatic discharge (ESD) protection while operating in extended temperature environments is invaluable to industrial network implementation.

    But what they share in common is the goal to deliver real-time Ethernet to industrial automation applications under harsh environmental conditions. The typical elements of an industrial network might include programmable logic controllers (PLCs), motor controllers and drives, sensor networks and human machine interfaces (HMIs). These elements are connected on the Ethernet backbone using a protocol such as EtherCAT or Profinet. The network topology might be hub-spoke (star) or linear. Regardless of network topology, the goal is to provide precise control and synchronized timing information to each of the nodes. If the topology is a long daisy chain, then each node has to perform with the most optimized latency to enable fast request/response cycle times through the system.Figure1-IndustrialConnectivity

    Looking for a Low-Latency PHY?

    Protocols such as EtherCAT have to process the Ethernet packet and insert new data into the frame as it passes through in real-time. For real-time applications, this imposes tight restrictions on the latency through the switch and PHY. With this requirement in mind, we designed the Marvell 88E1510P/1512P/1510Q family of PHY products to address the stringent latency needs of tier-1 industrial customers. The table below shows that the Marvell low-latency PHY operates 30-40 percent faster as compared to non-optimized implementations. Figure2-Default-transmit While the data shown above is the default configuration, significantly lower latencies are possible with register programming. The sum total of transmit and receive latency was less than 400ns across the entire range, as shown below. Figure3-Lessthan400ns The small latency variation observed (from min to max) is due to the presence of synchronization circuits in the transmit path. Typically a FIFO (first in, first out queue) is used in the transmit path to compensate for any PPM (parts-per-million) differences between the transmit circuits and receiving circuits. Depending on packet size and the number of entries in the FIFO, a small variation in latency can be observed. (Note: When the PHY is used for precision-time protocol- (PTP-) based timestamping applications, the presence of the FIFO does not affect the accuracy of the timestamps.

    Future Proof with 1000BASE-T

    Since the installation of industrial equipment and networks is capital-intensive, it is prudent to use a PHY device that can future-proof network speed requirements up to 1000BASE-T. The Marvell 88E1510P/1512P/1510Q family of PHY products supports 10BASE-T, 100BASE-TX, and 1000BASE-T. The low latency ranges observed in 1000BASE-T mode is shown below.Figure4-Lessthan400ns

    Extended Temperature Operation and ESD support

    Industrial motors and robots connected by an Ethernet network often have to weld metals at very high temperatures. Figure5-Ethernetcomponents- This requires the PHY to operate in environments where the ambient temperature remains high throughout the entire duration of operation (for more than several hours). The Marvell 88E1510P/1512P/1510Q family of PHY products was designed to operate in ambient operating temperature ranges of minus -40 0C to 85 0C degrees (or 125 0C maximum junction temperature.) 

    Packaging and Interface Options

    The Marvell 88E1510P/1512P/1510Q family of PHYs is offered in 48-pin or 56-pin QFN packages. It also offers a variety of host interface options such as RGMII, MII and SGMII. For information on specific features, please review the attached product selector guide.

    Marvell 推出业内初个面向汽车业的 IEEE 千兆以太网

    By Anil Gercekci, Director of Technical Marketing of Automotive Solutions Group, Marvell

    High-Speed Networking Becomes a Reality For Automotive 

    Creating New Consumer Features

    Marvell First to Deliver Samples to Auto Manufacturers 

    With the availability of high-speed LTE networks and the thrust toward autonomous driving, car companies are working on a structured approach to high-speed data distribution to and within vehicles. Today, Gigabit Ethernet over a single pair of twisted-pair copper wire has become a reality for the automotive industry paving the way for high-speed networking within a vehicle. In November of last year, Marvell delivered the first samples based on the IEEE 1000BASE-T1 pre-standard specification for verification of performance in vehicles. The 1000BASE-T1 standard allows high-speed and bi-directional data traffic over light-weight, low-cost, single-pair cable harnesses. This enables car companies to create a whole new array of exciting automotive features and benefits. Early chip samples from Marvell allow auto makers the ability to evaluate the performance of this new standard and identify possible issues early in the application development process, prior to production, to accelerate time to market.  

      Gigabit-Ethernet-Chart  

    Industry Standards Organizations Paving the Way to Seamless Automotive Wireless Communications 

     历史上的诸多第一次

    In 2011, Marvell was a key driver in the Call For Interest (CFI) at IEEE for an Automotive-specific Gigabit Ethernet PHY. This CFI received unanimous support (a relatively rare event in IEEE) and now the new IEEE 802.1bp standard is set to be ratified in 2016. In the meantime, Marvell has already begun sampling pre-standard parts to the industry for testing.

    Will Automotive Become the Largest IT Employer In the Near Future?

    The automotive industry is rapidly adopting Ethernet as a key enabler, not only for its superior price/performance, but also because it supports the Open Systems Interconnection (OSI) model. The OSI model allows for the rapid deployment of applications and services. Using this layered approach, a specific PHY technology, which met both the light weight and low EMC requirements, had to be developed that was consistent with all the existing upper layers of the OSI model. This gives the benefits of being able to leverage and reuse existing developments in layers above the PHY level. It is amazing to think that with this unprecedented potential expansion of automotive connectivity and its applications, it is conceivable that the automotive industry could become the world's largest employer of IT experts in the coming years. 

    More to Come

    In addition to a long history of WiFi and Bluetooth combo products in automotive, Marvell is enabling WiFi technology to become part of this external connectivity by developing 802.11ai technology that allows for Fast Initial Link Setup (FILS) that provides opportunistic access to base stations whenever they become available as the car drives at high speed. In addition, 802.11p products will enable short-range wireless connectivity for collision avoidance or pedestrian/cyclist detection, applications that demand quick response and are not possible via current Light Detection and Ranging (LIDAR) and LTE technologies. With these wireless technologies placed in the roof of the car, Ethernet plays an important role for high-speed communication to and within the vehicle. By delivering early samples based on the latest developing industry standards, Marvell is helping to “drive” new applications in automotive connectivity technology.

    You’ve seen it, the dreaded buffering while trying to stream a movie, lag times while gaming or dropped signals as you walk through your home.   But all this is a thing of the past with the latest products based on Marvell’s Gigabit Home Networking (G.hn) Powerline Communications technology. Marvell G.hn chip sets combine powerline, coax, phone line/twisted pair and optical fiber in a single technology, which can turn a home’s electrical, coaxial and anywire smart grids into high-speed internet and connected devices. ArrisSURFboard

    Take for example the new line of ARRIS routers and extenders, the SURFboard® family of home networking devices with RipCurrent™ G.hn technology.  This new system of routers and extenders, based on Marvell technology, is designed to eliminate the frustrations that have plagued home wireless as more and more family members use more and more devices.  The RipCurrent-enabled routers and extenders use existing powerlines (electrical outlets) in the home to create new hotspots to connect high-bandwidth devices and relieve home Wi-Fi congestion. 

    Range is no longer an issue and interruptions become non-existent. (Where’s dad?

    And while ARRIS International plc was the top cable modem retailer in 2016, they aren’t the only ones where Marvell G.hn Powerline is playing an integral role. Last summer, Comtrend, a leading designer and manufacturer of broadband communication equipment, launched its first G.hn powerline-only adapter in retail. COMTREND G.hn offers the flexibility of providing high bandwidth for in-home networking using both a wired medium and wireless extender setting.  

    With no more dead zones, Marvell G.hn powerline technology is helping redefine home networking and improving the home Wi-Fi experience.

    With OEMs racing to offer connected car services, Marvell has developed a new Ethernet reference platform integrated with TE Connectivity's (TE) MATEnet modular and scalable connectors for automotive Ethernet, to enable a faster time-to-market for Gigabit Ethernet in automotive systems. 新的开发平台以 100BASE-T1 和 1000BASE-T1 以太网物理层 (PHY) 性能,支持音频桥接 (AVB) 交换机解决方案。 制造商现在可以将千兆以太网用于电子和电气架构,快速制作车载系统原型。

    下一代汽车技术需要能够在汽车鲁棒状态下运行的高速、弹性数据基础设施。 自动驾驶、高级安全功能,以及沉浸式信息娱乐系统等应用程序,正在不断推进这些新架构的发展。 Combining Marvell's expertise in network and Ethernet, with TE's experience in providing real world automotive connector and cable systems, this development platform allows vehicle architects to begin designing these systems for mass production.

    This new reference platform includes support for the AVB networking standards of the AVnu Alliance's certification test subgroup and also supports Stream Reservation Protocol to provide end-to-end management of resource reservations for automotive data streams. In addition, Marvell's Ethernet PHY transceivers (88Q2112 100BASE-T1 PHY and 88Q1010 100BASE-T1 PHY) enable high definition and uncompressed video, high speed links, between domains to support connected and autonomous driving systems and the fastest system bring up from power down. 更多功能和优势包括:时效性网络技术(用以支持时间先决控制应用),车对车 Wi-Fi 通信(以使用针对交通和道路状况的实时提醒来提高安全性并缩短响应时间)。 The 88Q2112 is the industry's first 1000BASE-T1 automotive Ethernet PHY transistor that is compliant with the draft IEEE 802.3bp 1000BASE-T1 standard.

    Marvell's commitment to extend connectivity to the automobile includes a number of solutions to meet the needs of designers for the cars of the future.
