Description

The Arista 7280R3K is a 1RU fixed data centre switch router built for internet peering, data centre interconnect, EVPN/VXLAN fabrics and carrier-edge or core routing. This DCS-7280DR3K-24-FLX-F variant carries 24 x 400GbE QSFP-DD ports and the large-route (K) forwarding tables, and it runs Arista EOS.

The switch delivers 9.6 Tbps of throughput (19.2 Tbps full duplex) and 4 Bpps forwarding, with latency from 3.8 us and a 16 GB deep packet buffer using Virtual Output Queues. Breakout options extend the 24 ports to up to 96 x 100G, 192 x 50G or 192 x 25/10G interfaces. It is fitted with 2 x hot-swap AC power supplies in a 1+1 arrangement and 3 x hot-swap fans in an N+1 arrangement, with front-to-rear airflow. This SKU is the FLX licence bundle, and it uses Group 4 fixed-switch licensing.

The ports accept 400G QSFP-DD optics and cables including 400GBASE-CR8, AOC, SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR, plus QSFP-DD to QSFP/SFP breakout cables. The system is managed through CloudVision and requires EOS 4.23.1 or later.
