Description

The Arista 7280R2K is a 2RU deep-buffer data centre switch router built for cloud-scale leaf, spine, edge and internet-peering roles where large routing tables, deep packet buffers and high 100G density are required. It runs Arista EOS, a single binary image with self-healing software.

This SKU provides 60 x QSFP100 ports with 12 Tbps of full-duplex throughput and 5.02 Bpps. The ports can be configured for up to 120 x 50GbE, 60 x 40GbE, 240 x 25GbE or 240 x 10GbE using optics or breakout cables. It includes 24 GB of packet buffer, latency from 3.8 us and AlgoMatch-2 for IPv4 and IPv6 ACL scale. This variant uses two hot-swap 1900W DC power supplies in a 1+1 arrangement, four hot-swap fans in N+1 and front-to-rear airflow.

It supports QSFP100, QSFP+ and SFP-based optics and DACs through breakout, including 100GBASE-CR4 and 40GBASE-CR4, AOC, SR-BD and UNIV. The fan tray is FAN-7002H-F and the DC power supply is PWR-1900-DC.
