Description

The Arista 7280R is a 2RU fixed-configuration data centre switch router built for high-density 100G leaf and spine deployments, data centre core roles, and cloud or service-provider routing and peering where deep buffers and high-scale ACL and telemetry are needed.

This model provides 60 x 100GbE QSFP100 ports with 12 Tbps of full-duplex throughput, a 5.02 Bpps forwarding rate and latency from 3.8 us. A 24 GB packet buffer, 16 GB of system memory and 4 GB of flash with an included SSD support demanding workloads. Each port can run at 100GbE, 50GbE, 40GbE, 25GbE or 10GbE through optics or breakout cables. This SKU is the DC-powered variant with two hot-swap 1900W DC power supplies in a 1+1 redundant arrangement, four N+1 hot-swap fans with front-to-rear airflow, and AlgoMatch for scalable access control, policy-based forwarding and telemetry. It differs from the -60-F model, which uses two AC supplies.

The platform runs Arista EOS and requires EOS Feature License Group 4, with a minimum of EOS 4.19.1. The QSFP ports accept 100GBASE-SR4, LR4, CWDM4, FR, DR, PSM4 and ERL4 optics, as well as AOC and CR4 DAC cables, and 40G QSFP+ optics and cables. The switch is managed with CloudVision.
