Overview

The Arista 7050X4 series is the fourth generation of the Arista 7050X family and a key

component of the Arista 400G portfolio of data center switches.

As enterprises continue to optimize data center facilities for modern cloud-native

applications, collaboration tools, containerized services and emerging AI/ML

technologies, the requirement for high capacity, low latency networking is driving a

attening of data center architectures and high bandwidth interconnectivity

between facilities and the public cloud.

400G Ethernet is a key enabler in realizing modern high performance infrastructure,

o ering the ability to not only carry large volumes of data, but also to signi cantly

increase the radix of 100Gbps networks and to support emerging 50/100/200Gbps

server and storage connectivity driven by the adoption of PCIe® Gen4.

The Arista 7050X4 Series high performance exible data center switches provide

support for a wide range of interface speeds, a broad set of wire speed, low latency

L2 and L3 Enterprise features including EVPN/VXLAN and extensive automation and

programmability with Arista’s EOS for industry leading software driven cloud

networking.

All models of the 7050X4 Series o er exible forwarding tables, latency from as low

as 900 ns and a shared packet bu er of up to 132 MB for superior burst absorption.

Comprehensive support for a wide range of interface speeds including 10G, 25G,

40G, 50G, 100G, 200G and 400G combined with Arista EOS ensures the 7050X4

delivers the exibility for enterprises deploying emerging applications, scaling up

existing facilities or consolidating multi-tiered networks into e cient leaf-spine

topologies.

Arista 7050X4 Series

Arista EOS

The Arista 7050X4 series run 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.

Arista’s 64-bit EOS is purpose built for high performance, large scale workloads and

embeds advanced monitoring, telemetry and automation capabilities. With a

powerful x86 CPU subsystem and full access to Linux, a wealth of standard tools can

also be run natively on the switch for simple integration into automation work ows.
