Description

The Arista 7280R2K is a 2RU fixed-configuration data centre switch router built for deep-buffer leaf-spine and spine designs, internet peering and high-density 100G aggregation in cloud, service provider and large enterprise networks.

This model provides 60 x 100GbE QSFP100 ports, with breakout to up to 120 x 50GbE, 240 x 25GbE or 240 x 10GbE. It delivers 12 Tbps of full-duplex throughput and a 5.02 Bpps forwarding rate, with latency from 3.8 us. A virtual output queue architecture is backed by 24 GB of packet buffer, and AlgoMatch-2 provides large-scale routing and ACL capacity. The system has 16 GB of memory and 4 GB of flash, and runs Arista EOS with Feature License Group 4 (minimum EOS 4.20.1). Airflow is front-to-rear, and power comes from two hot-swap 1900W AC supplies in a 1+1 arrangement, with four N+1 hot-swap fans.

The QSFP100 ports accept 10G SFP+, 25G SFP, 40G QSFP+ and 100G QSFP optics and cables, including SR4, LR4, CWDM4, PSM4, AOC and CR4 DAC types. The fan tray is FAN-7002H-F and the power supply is PWR-1900AC-F.
