Description

The 7280R 72-port 40G switch is a 2RU data centre switch router from Arista's 7280R family, built for large-scale layer 2 and layer 3 cloud designs, overlay networks, virtualised or traditional enterprise data centres, and internet peering and inter-DC networking that need deep buffers and large routing tables. It is typically deployed as a high-density 40G and 100G leaf.

There are 72 QSFP ports, made up of 56 QSFP+ and 16 QSFP100. Depending on optics and breakout, that gives up to 72x 40GbE, 16x 100GbE, 32x 50GbE, 64x 25GbE or 160x 10GbE. Throughput is 6.4 Tbps at 2.88 Bpps, backed by a 16 GB packet buffer. This SKU has expanded system memory and a built-in SSD for logging and data captures. Power comes from 2x 1900W AC hot-swap supplies in a 1+1 arrangement, with four hot-swap fans in N+1 and rear-to-front airflow.

The switch runs Arista EOS 4.18.1 or later and is managed with CloudVision. QSFP+ and QSFP100 optics and cables are supported, and the QSFP100 ports also run 10GbE, 25GbE and 50GbE through breakout. It sits in EOS Feature License Group 3, with optional licences for enhanced L3, virtualisation, and monitoring and automation.
