Overview

The expansion of applications for machine learning and arti cial intelligence driven

by faster CPUs, ash storage and server less compute is driving the next generation

of datacenter cloud networks based on 100G and 400G Ethernet. Evolution to the

next generation requires systems that deliver optimized performance, addressing

the growth and increased scale of modern cloud environments, in addition to

compatibility with existing 100G and 400G networks in a consistent and proven

architecture.

The Arista 7368X4 series is built on a single 12.8 Tbps high capacity packet processor

in an extremely compact 4RU form factor that increases the network radix for high

density switching, reduces tiers and simpli es networks. Line rate performance and

proven layer 2 and layer 3 features with up to 128 ports of 100G or 32 ports of 400G

provides signi cant improvements to both system density and power e ciency. In

addition to the high performance and density the 7368X4 delivers advances in

tra c awareness, congestion handling and instrumentation to allow network wide

visibility and monitoring.

The Arista 7368X4, with the Arista 7060X and 7260X portfolio of data center

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

and 400G enabling consistent network architectures that seamlessly scale from small

dedicated clusters to the needs of the largest multi-tier hyper-scale cloud networks.

All elements of the 7368X4 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 7368X4 series deliver advanced features for hyper-

scale networks, server-less compute, big data farms and machine learning clusters.

Arista EOS

The Arista 7368X4 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.
