The Arista DCS-7280DR3-24 is a 400G data center switch from the Arista 7280R3 Series. It is built in a 1U rack form factor and provides 24 × 400G QSFP-DD ports. It is backed by a non-blocking switch fabric architecture with 9.6 Tbps of system throughput and 19.2 Tbps of backplane bandwidth.
The switch runs Arista EOS and includes 1 × 1GbE RJ45 management port. Power is supplied by dual AC PSUs, with a maximum power consumption of 2.8 kW. Cooling uses front-to-back airflow.
The DCS-7280DR3-24 is intended for data center edge, IP routing, WAN peering and telco operator deployments. In these environments, high-density 400G connectivity in a compact rack footprint supports aggregation and interconnection of network traffic.
