Description

The Arista 7280R3 Series 7280CR3-36S is a 1RU fixed-configuration data centre switch router built for cloud networking, content delivery, service provider, IP storage and data centre leaf and spine deployments. It combines 100G density with 200G and 400G flexibility, deep buffers and the FlexRoute engine for internet-scale routing and peering.

The front panel provides 28 x QSFP100, 6 x QSFP200 and 2 x QSFP-DD ports, supporting up to 2 x 400G, 40 x 100G, 80 x 50G, 36 x 40G or 120 x 25/10G interfaces through breakout. Throughput is 2.4 Tbps (4.8 Tbps FDX) at 1 Bpps, with latency from 3.8 us and a 4 GB packet buffer. It has a quad-core x86 CPU and 64 GB of system memory. This SKU is the FLX routing licence model with rear-to-front airflow, using the FAN-7011H-R fan module, and two hot-swap AC power supplies in a 1+1 arrangement. Typical power draw is 254 W with a maximum of 423 W.

The ports accept QSFP100, QSFP200 and QSFP-DD optics and cables, with breakout to lower speeds subject to transceiver and cable capability. It runs Arista EOS 4.26.1 or later, and rear-to-front airflow requires EOS 4.29.1 or later.
