Description

The Arista 7280R3 is a 1RU fixed data centre switch router built for large-scale cloud, data centre and service provider routing. It suits leaf-spine and EVPN/VXLAN overlay designs, internet peering and interconnect, inter-DC networking, and carrier edge and core roles.

This model provides 24 wire-speed 400G OSFP ports, with breakout to as many as 96 x 100G, 192 x 50G or 192 x 25/10G interfaces. Throughput is 9.6 Tbps (19.2 Tbps full duplex) and 4 Bpps, with latency from 3.8 us and a 16 GB deep packet buffer. The expanded-memory variant carries 64 GB of system memory and a 120 GB SSD alongside a quad-core x86 CPU. It runs Arista EOS, with the EOS feature licence group listed as Group 4 and a minimum release of 4.22.2. Dual hot-swap 1+1 PWR-1511 power supplies and three N+1 hot-swap FAN-7011H fans provide redundancy, with front-to-rear airflow and a typical draw of 650 W.

The OSFP ports accept 400GBASE-SR8, DR4, XDR4, FR4, 2FR4, LR4, PLR4 and ZR optics, as well as 400G DAC and AOC cables. The switch is managed through Arista CloudVision.
