Description

The Arista 7280R2 is a 2RU fixed data centre switch router with 60 QSFP100 ports and 12 Tbps of wire-speed Layer 2 and Layer 3 forwarding. Its deep-buffer virtual output queue architecture with 24 GB of packet buffer suits cloud leaf-spine and spine roles, service provider and internet-peering routing, and DC-powered or telco-style sites.

Each 100GbE port also supports 40GbE, 50GbE and 4x 10GbE or 25GbE breakout, for up to 240 ports at 10G or 25G. Throughput is 5.02 Bpps with latency from 3.8 us. This SKU is the front-to-rear airflow model with two 1900W DC power supplies (PWR-1900-DC, 40-72 VDC input, 1+1 redundant) and four FAN-7002H-F hot-swap fans in an N+1 arrangement. It does not include AlgoMatch. Typical power draw is 1660W and maximum is 1850W.

The QSFP ports accept SR4, XSR4, SWDM4, SRBD, LR, LR4, CWDM4, FR, DR, PSM4 and ERL4 optics as well as AOC and CR4 cables, along with 40G QSFP+ optics. The switch runs Arista EOS from release 4.20.2 and is managed with CloudVision.
