Description

The Arista 7280R3 series is a family of fixed data centre switch routers, and this model is a 1RU platform built for leaf and spine designs, Internet peering, carrier edge and metro services, and AI or cloud cluster networking. It forwards at wire speed at Layer 2 and Layer 3 and runs Arista EOS, managed through CloudVision.

The front panel provides 32 x 100GbE QSFP100 ports and 4 x 400GbE QSFP-DD ports, with breakout to 50G, 25G and 10G and support for 40G QSFP+. Throughput is 4.8 Tbps (9.6 Tbps full duplex) at 2 Bpps, with latency from 3.8 us and an 8GB packet buffer. This -M variant ships with expanded 64GB system memory. Fans and power supplies are configurable and ordered separately, with 2 hot-swap power supplies (1+1) and 3 hot-swap fans (N+1) in the chassis. Typical power draw is 535W, with a maximum of 851W.

It accepts 100G QSFP100 and 400G QSFP-DD optics and cables. The matching fan tray is FAN-7011H and the power supplies are PWR-1011 in AC or DC. EOS Feature License Group 3 applies, with optional software licences such as LIC-FIX-3-E available separately.
