Description

The Arista 7280R2A is a 1RU fixed data centre switch router built for spine and leaf designs, layer 2 and layer 3 cloud fabrics, overlay networks and service provider or high-performance environments. Its deep-buffer virtual output queue architecture suits bursty and storage-heavy traffic, with lossless forwarding as a design target.

This SKU provides 30 QSFP100 ports, each running at 100GbE, 50GbE, 40GbE, or as 4x10GbE and 4x25GbE breakout for up to 120 lower-speed ports. Throughput is 6 Tbps full duplex with 2.51 Bpps of packet forwarding and latency from 3.8 us. It includes AlgoMatch, expanded memory, front-to-rear airflow and two 1600W AC hot-swap power supplies in a 1+1 arrangement, with five hot-swap N+1 fans. It runs Arista EOS with EOS Feature License Group 3 and requires EOS 4.20.3 or later.

The QSFP100 ports accept 100GBASE SR4, XSR4, SWDM4, SRBD, LR, LR4/LRL4, CWDM4, XCWDM4, FR, DR, PSM4 and ERL4 optics, as well as AOC and CR4 cables. 40G QSFP+ optics and DACs are also supported.
