Arista Networks

Arista Networks, headquartered in Santa Clara, California, is a leading supplier of cloud-scale networking hardware and software for data centres, AI clusters, and wide-area campus networks. Its EOS (Extensible Operating System) is a single Linux-based network operating system that runs across the entire portfolio of fixed-configuration and modular data-centre switches, enabling programmable network automation. Arista is the dominant networking vendor in hyperscaler-adjacent data-centre deployments and is rapidly expanding into AI fabric networking, where its ultra-low-latency switches interconnect GPU clusters for large model training. The company collaborates with university networks research groups and funds academic chairs at Stanford, Carnegie Mellon, and Edinburgh on topics including network telemetry, intent-based networking, and high-performance computing interconnects. Many research computing centres at universities deploy Arista switching in their HPC clusters and GPU farms.
