Overview

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. In addition to the need for next generation

systems that deliver higher scale, optimized for cost and energy e ciency,

enterprises require rich functionality and broad compatibility with existing networks

and automation and orchestration systems.

The Arista 7358X4 series is built on a single 12.8 Tbps high capacity packet processor

in an extremely compact and power e cient 4RU modular form factor that increases

the network radix for high density switching, reduces tiers and simpli es networks

while providing exibility to deploy a range of interface types. Line rate performance

with up to 128 ports of 100G or 32 ports of 400G combined with broad support for

enterprise grade features including EVPN/VXLAN.

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

7358X4, with the Arista 7050X4 and 7050X3 portfolio of data center switches,

delivers a rich choice of port speed and density including 25G, 50G, 100G, 200G and

400G enabling consistent network architectures that scale from small dedicated

clusters to very large multi-tier and multi-plane topologies.

All elements of the 7358X4 are eld replaceable, and optimized for simple

maintenance, a broad range of network interfaces with a choice of industry standard

interfaces allowing for easy transitions to the latest 100G/400G networks. Combined

with Arista EOS the 7358X4 series deliver advanced features for high performance

enterprise data centers, HPC and machine learning clusters.

Arista EOS

The Arista 7358X4 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.

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.
