Overview

The Arista 7050CX3M are members of the Arista 7050X series and key components

of the Arista portfolio of data center switches. The 7050X3 MACsec systems are high

performance systems with built-in wire speed MACsec encryption for the needs of

next generation datacenters. The adoption of high performance servers using

virtualization and containers with increasingly higher bandwidth is accelerating the

need for dense 25 and 100G Ethernet switching in both the leaf and spine tiers of

modern networks. The Arista 7050X3 Series are high performance exible data

center switches with a rich set of wire speed L2 and L3 features combined with

extensive automation and programmability capabilities, low latency and consistent

features for software driven cloud networking.

The 7050CX3M built-in MACsec capability removes the need for external encryption

devices and provides security against intrusion, passive wire tapping and other

playback attacks. MACsec encryption meets regulatory compliance requirements

and provides data protection without loss of performance.

The Arista MACsec solution utilizes proven encryption technology to protect tra c

for simple, reliable and scalable data center interconnect and for securing links

between tiers in leaf and spine data center designs. MACsec o ers security in the

data link layer and is transparent and non-disruptive to L2/L3 tra c. Flexible 100GbE

and 40GbE QSFP pluggable optics ensures a broad choice of cost e ective

connections.

Combining high density and industry leading power e ciency with typical power

consumption under 10W per 100GbE port the 7050CX3M-32S is ideal for both high

performance leaf or collapsed spine tiers with air ow choices for back to front, or

front to back. The 7050CX3M Series o er exible forwarding tables with a Uni ed

Forwarding Table, latency from 800ns and a fully shared packet bu er of up to 32MB

for superior burst absorption. Comprehensive support for a wide range of interface

speeds including 10G, 25G, 40G, 50G and 100G combined with Arista EOS ensures

the 7050CX3M delivers the exibility and features for big data, cloud, virtualized and

traditional network designs and accommodates the myriad di erent applications

and east-west tra c patterns found in modern data centers.

Arista EOS

The Arista 7050CX3M series runs the same Arista EOS software as all Arista products,

simplifying network administration. Arista EOS is a modular switch operating system

with a unique state sharing architecture that cleanly separates switch state from

protocol processing and application logic. Built on top of a standard Linux kernel, all

EOS processes run in their own protected memory space and exchange state

through an in-memory database. This multi-process state sharing architecture

provides the foundation for in-service-software updates and self-healing resiliency.

With Arista EOS, advanced monitoring and automation capabilities such as Zero

Touch Provisioning, VMTracer and Linux based tools can be run natively on the

switch with the powerful x86 CPU subsystem.
