Description

The Arista DCS-7280SRA-48C6M-R is a 1RU 7280RA data centre switch router with 48 x 1/10GbE SFP+ ports and 6 x 100GbE QSFP100 uplinks. It delivers 2.16 Tbps of wire-speed throughput at 720 Mpps with 4 GB of deep packet buffer, making it well suited to data centre leaf, spine and edge routing roles where buffering and large forwarding tables matter.

This SKU is the rear-to-front airflow model with expanded memory, an included SSD and two 500W AC hot-swap power supplies in a 1+1 redundant configuration. AlgoMatch provides scalable ACL, policy-based forwarding and telemetry, and the QSFP100 ports support 10/25/40/50/100GbE breakout modes. It runs Arista EOS with a single binary image, eAPI, CloudVision integration and Zero Touch Provisioning.
