Redefining Scaleability

EOS Core

At the core of Arista’s platform is EOS, the world’s most advanced network operating system. EOS is one of the factors in Arista’s prominence in the “Leaders” Quadrant of Gartner’s latest Data Center Networking analysis. In embracing open standards, EOS puts Arista at the heart of an ecosystem of vendors including Infrasys partners Palo Alto and VMware. Recent enhancements to CloudEOS provide native support for AWS Cloud WAN Tunnel-less Connect. Tunnel-less Connect allows customers to directly BGP peer the virtual router deployed in a Transit VPC to AWS Cloud WAN without the need for a tunnel, simplifying configurations and operations and allowing utilisation of AWS’s high bandwidth global network for site-to-site and site-to-cloud connectivity. Multi-cloud, open and programmable, and with features including TAP Aggregation and containerisation support, Arista is the leading vendor of high density, non-blocking networks at any scale.

Unique Architecture

Based on a unique multi-process state sharing architecture, Arista’s range of 10G, 25, 40G, 100G, 400G and 800G switches all run a single OS, bringing easy management and cloud-scale economics to the datacentre. High port density and low cost per port have extended Arista’s use case footprint from ultra low latency to IP storage and Big Data.
