Description

The Arista 7280R3 Series DCS-7280PR3-24-F is a 1RU fixed data centre switch router with 24 x 400G OSFP ports and 9.6 Tbps of wire-speed throughput. It suits large-scale cloud and data centre L2/L3 designs, EVPN fabrics, internet peering, interconnect and inter-DC networking, as well as carrier edge VPN services, 5G/MEC and metro transport.

Each OSFP port runs at 400G and can break out to 4 x 100G, giving up to 96 x 100G ports, with maximum port counts depending on transceiver and cable support. It forwards 4 Bpps with latency from 3.8 us and carries a 16 GB packet buffer with Virtual Output Queues to avoid head-of-line blocking. This variant has front-to-rear airflow and two hot-swap 1500W AC power supplies in a 1+1 redundant arrangement, backed by three N+1 hot-swappable fans. A quad-core x86 CPU with 8 GB of system memory and a 120 GB SSD drives the control plane.

It runs Arista EOS and belongs to EOS Feature License Group 4, with a minimum of EOS 4.22.2. It is managed by Arista CloudVision and works with 400G OSFP optics and cables.
