Description

The Arista 7280R2K is a 1RU fixed data centre switch router from the 7280R series, built for large-scale layer 2 and layer 3 cloud designs, overlay networks, internet peering, interconnect and inter-DC networking. Deep buffers and large routing tables make it suited to service provider and enterprise data centre environments.

This SKU provides 30x 100GbE QSFP100 ports, which also support 50G, 40G, 25G and 10G modes, giving up to 120 breakout 25G or 10G ports. It delivers 6 Tbps of full-duplex throughput, a 2.51 Bpps forwarding rate, a 12 GB packet buffer and latency from 3.8 us. As a 7280R2K model with AlgoMatch-2 and expanded route memory, it supports over 2M IPv4 routes. Airflow is front-to-rear, with two 1600W AC hot-swap power supplies in a 1+1 arrangement and five hot-swap fans. Typical power draw is 565 W, with a maximum of 750 W.

The QSFP100 ports accept 100GBASE-SR4, LR4, CWDM4, PSM4 and other 100G optics, AOC and CR4 cables, as well as 40G QSFP+ optics and DACs. The switch runs Arista EOS 4.20.3 or later, sits in EOS Feature License Group 3 and integrates with CloudVision.
