High-density 40GbE/10GbE Packet Processor for Carrier and Enterprise Applications
Prestera CX Ethernet Switch Family
PRODUCT OVERVIEW
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.

The Prestera CX Family has sophisticated QoS features to optimize QoS between data center cloud applications, such as metering, counting, scheduling, and shaping. It also supports advanced traffic monitoring features such as sFlow, IPFIX, and remote port analyzing. The hardware OAM engines auto-generate and receive OAM traffic to monitor cloud end-to-end service connectivity and provide high accuracy delay and packet loss measurement.

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.

APPLICATIONS
The Prestera 98CX8129 is a 640Gbps packet processor that enables performance- and cost-optimized solutions for a broad range of platforms in the campus, service provider and datacenter environments. In addition, it has a full complement of L2/L3/L4 forwarding capabilities along with an advanced classification and policy engine. The Prestera CX devices are ideal for software defined networking (SDN), leveraging OpenFlow 1.3.1 with support for additional extensions in a virtualized or hybrid system design.

To shorten system manufacturers’ design cycles and accelerate time to market, Marvell provides complete development platforms and reference designs with schematics, layout files and related documentation.
