Description

The Arista 7280R3 is a 1RU fixed data centre switch router built for internet peering, interconnect, inter-DC networking and large-scale carrier or cloud spine and leaf deployments. It pairs wire-speed 400G ports with an ultra-deep 16GB packet buffer, so it suits networks that need large routing tables and burst tolerance.

This SKU provides 24 x 400G QSFP-DD ports, which can break out to as many as 96 x 100G, 192 x 50G or 192 x 25G/10G interfaces, with QSFP+ 40G supported on up to 24 ports. Throughput is 9.6 Tbps (19.2 Tbps full duplex) with 4 Bpps packet forwarding and latency from 3.8 us. A quad-core x86 CPU with 8GB system memory runs Arista EOS. It has front-to-rear airflow, two hot-swap 1500W AC power supplies in a 1+1 arrangement and three hot-swap fans in an N+1 arrangement. Typical power draw is 650W, with a maximum of 1100W.

The 7280R3 falls in EOS Feature License Group 4, with optional licences available for enhanced Layer 3 routing, virtualisation, security extensions and monitoring and automation. Spare parts include the PWR-1511 power supply family, FAN-7011H fan modules and the KIT-7001 and KIT-2POST-1U-NT rack kits.
