Description

The Arista 7280R3 DCS-7280DR3K-24-F is a 1RU fixed-configuration data centre switch router with 24 wire-speed 400G QSFP-DD ports and 16GB of deep packet buffer. The K variant adds large routing-table scale through the FlexRoute engine, making it suited to internet peering, data centre interconnect, spine roles and carrier or service provider cores running MPLS and SR-TE.

Throughput is 9.6 Tbps (19.2 Tbps full duplex) with 4 Bpps forwarding and latency from 3.8 us. Every 400G port can break out to 100G, 50G, 25G or 10G, up to 192 interfaces in total, and 40G is supported through QSFP+. The platform has 64GB of system memory and a 120GB SSD, with 2 hot-swap AC power supplies in 1+1 redundancy and 3 hot-swap fans in N+1 redundancy. Airflow is front to rear. Typical power draw is 650W with a 1100W maximum.

The switch runs Arista EOS, with a minimum release of 4.23.1 and Group 4 EOS feature licences. It is managed through CloudVision and supports EVPN-VXLAN, PTP and SyncE timing, and LANZ microburst detection.
