Description

The Arista 7280R3 is a 1RU fixed-configuration data centre switch router built for leaf, spine and Internet peering roles. It combines 32 x 100G QSFP100 ports with 4 x 400G QSFP-DD ports and runs Arista EOS, making it a fit for large cloud, big data and routing-heavy environments that need deep buffering.

The 7280CR3-32D4 delivers 4.8 Tbps of wire-speed throughput (9.6 Tbps full duplex) and 2 Bpps of packet forwarding, with latency from 3.8 us and an 8 GB packet buffer. Ports can be configured for up to 48 x 100G, 96 x 50G or 96 x 25/10G using breakout, subject to transceiver and cable support. This -R SKU has rear-to-front airflow with 2 x hot-swap AC power supplies (PWR-1011, 1+1 redundant) and 3 hot-swap fans (FAN-7011H, N+1). Typical power draw is 535 W, with a maximum of 851 W.

The QSFP100 ports also accept 40G QSFP+ optics, and the platform requires EOS 4.22.1 or later. It falls under EOS Feature License Group 3, with feature licence bundles purchased separately, and integrates with Arista CloudVision for management.
