Description

The Arista 7280R3 (7280CR3) is a fixed-configuration 1RU data centre switch router built for large-scale layer 2 and layer 3 cloud designs, leaf-spine and EVPN/VXLAN overlay networks, enterprise data centres, Internet peering and inter-DC interconnect. It runs Arista EOS as a single binary image.

This SKU provides 32 x 100G QSFP ports and 4 x 400G QSFP-DD ports, with 4.8 Tbps of wire-speed throughput, 2 Bpps packet forwarding, latency from 3.8 us and an 8GB deep packet buffer. It ships with front-to-rear airflow, two 1+1 redundant hot-swap AC power supplies (PWR-1011, 1000W output each) and three N+1 hot-swap fans (FAN-7011H). Typical power draw is 535 W, with a maximum of 851 W.

The QSFP-DD ports accept 400G optics and cables and support breakout to 2 x 200G or 4 x 100G. The QSFP ports support 40G and 100G optics and DACs, with 25G and 50G breakout. Fixed-switch feature licences are Group 3 and the minimum EOS release is 4.22.1.
