Arista joined the parade toward high-speed Ethernet with new switches capable of supporting 400G speeds and aimed at hyperscale cloud and data-center networks.

The Arista 7060X4 Series platforms are based on the Broadcom 12.8Tbps Tomahawk 3 silicon and feature 32 400G ports. Each 400G port can be split into four 100G ports for a total of 128 100G ports in a 1U chassis. Arista also enhanced its EOS operating system to better support traffic management, load balancing, buffering and routing for the high-speed boxes.
