Prestera CX


Prestera CX 以太网交换机芯片系列

The Marvell® Prestera® CX family of highly-integrated packet processors enables single and multi-chip solutions for public and private data center networks. The processors include new features for the coming massive growth of edge data centers built to handle the 5G and IOT trends.

The new CX Family introduces support for SAFE and FASTER technology to offer dramatic improvement in TCO for edge data center deployments.  Storage Aware Flow Engine (SAFE), enables advanced visibility and telemetry to improve utilization of composable infrastructure while Forwarding Architecture using Slices of Terabit Ethernet Routers (FASTER), enables a massive increase in port radix which reduces network layers saving in cost, power and latency.

With proven through deployment support of advanced data center features, such as virtual overlay networking with programmable tunnel header encapsulation, NFV service function chaining, low latency cut-through switching, and advanced congestion mechanisms, the Prestera CX family can be deployed in a variety of topologies and interconnect needs.

Prestera® CX 系列具备精密的 QoS 特性,可最大程度优化数据中心云应用之间的 QoS,例如测量、计算、调度和整形。 它还支持高级流量监测功能,例如 sFlow、IPFIX 和远程端口分析。 硬件 OAM 引擎自动生成和接收 OAM 流量,以监测云端到端服务的连接,并提供高精度的延迟和丢包测量。

New standards compliant congestion management capabilities in the device, including (but not limited to) Per-priority Flow Control and Enhanced Transmission Selection, allow finer grained responses to network congestion and assist in improving service delivery with deterministic network behavior. Support for Fibre Channel over Ethernet (FCoE) in the Prestera CX family enables the design and deployment of systems that facilitate the convergence of data and storage networks.

以太网从 LAN 互连持续发展为已聚合、增强的支持云基础设施的服务架构。 宽带连接的改善和以媒介为中心的消费类设备的激增,外加多核 CPU 和虚拟化技术的进步,共同推动公共云和私有云基础设施新模型的出现。 网络、计算和存储架构的持续进步,为服务交付创造了新的商机,在提高可靠性和弹性的同时降低了管理的复杂性。

The Marvell Prestera CX family is designed to provide Marvell customers with the necessary platform for building the new edge data center network infrastructure.
