Description

The Arista 7280R is a 1RU data centre switch router built for leaf and spine designs, cloud networks and Internet or route peering roles. This SKU provides 36 QSFP ports, made up of 24 QSFP+ ports for 40GbE and 12 QSFP100 ports for 100GbE, and runs Arista EOS.

It delivers up to 4.32 Tbps of wire-speed throughput and 1.44 Bpps of packet forwarding, with latency from 3.8 us and an 8 GB packet buffer. The ports can be run in 10G, 25G, 40G, 50G or 100G modes using optics or breakout cables, giving up to 144x 10GbE, 48x 25GbE or 12x 100GbE. This -M variant includes expanded system memory and an SSD, and the -R variant has rear-to-front airflow with two hot-swap AC power supplies in 1+1 redundancy and four N+1 fans. It falls in EOS Feature License Group 2 and needs EOS 4.17.1 or later.

The QSFP+ ports accept 40GBASE-SR4, XSR4, LR4, ER4, UNIV, SRBD, PLR4, AOC and CR4 optics and cables, plus 4x10G breakout. The QSFP100 ports accept 100GBASE-SR4, XSR4, SWDM4, SRBD, LR, LR4, CWDM4, FR, DR, PSM4, ERL4, AOC and CR4 options. Spare power supplies are PWR-745AC-R and PWR-745AC-F, and the fan tray is FAN-7000-F/R.
