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

Table 2: Advanced Features in Cavium FastLinQ Adapters for HPE CloudlineNetwork 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 .

VMware vSAN ReadyNode 原件可替换
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
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.

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.
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.
