Description

The Arista 7280RA is a 1RU fixed-configuration data centre switch router from the 7280R Series, built for large-scale layer 2/3 cloud and leaf-spine deployments, VXLAN overlay networks, internet peering and inter-DC interconnect. Deep packet buffers, a virtual output queue architecture and AlgoMatch suit environments that need large routing tables and predictable behaviour under heavy load.

This 'M' variant has 36 QSFP ports (24x QSFP+ and 12x QSFP100), configurable as 18x 40GbE plus 12x 100GbE, and supports up to 12x100GbE, 36x40GbE, 24x50GbE, 48x25GbE or 120x10GbE. It delivers 3.84 Tbps full duplex and 1.44 Bpps with latency from 3.8 us, and carries 8 GB of packet buffer. Expanded system memory and an SSD set it apart from the base model. Power is two hot-swap 747W AC supplies in a 1+1 arrangement, with four N+1 fans and front-to-rear airflow.

The switch accepts QSFP+ (40G) and QSFP100 optics and DACs, and runs Arista EOS (minimum 4.19.0) in Feature License Group 2. It is managed through CloudVision and supports Zero Touch Provisioning.
