Description

The Arista DCS-7280CR3K-32P4-F is a 1RU fixed data centre switch router from the 7280R3 Series, built with 32 x 100GbE QSFP100 ports and 4 x 400GbE OSFP ports. This is the large routes (7280R3K) model, supplied with front-to-rear airflow and two AC power supplies, making it well suited to leaf, spine and peering roles in high-density data centre and service provider networks.

Deep 8 GB packet buffers, 4.8 Tbps of throughput (9.6 Tbps full duplex) and 2 Bpps forwarding keep traffic moving under bursty, mixed workloads. It runs Arista EOS with CloudVision, ZTP, eAPI, NETCONF and gNMI for automation, and supports EVPN/VXLAN, MPLS and Segment Routing services alongside redundant hot-swap power supplies and fans.
