Description

The Arista 7280R is a 1RU data centre switch router built for high-density 10/25/40/50/100GbE leaf and spine designs. This model suits deep-buffer, congestion-sensitive workloads such as mixed real-time, multicast and storage traffic, as well as internet route peering and VXLAN-based data centre fabrics.

It provides 36 QSFP ports in total, made up of 24 x 40GbE QSFP+ and 12 x 100GbE QSFP100. Port combinations scale up to 12x100GbE, 36x40GbE, 24x50GbE, 48x25GbE or 144x10GbE. Throughput is up to 4.32 Tbps full duplex at 1.44 Bpps, backed by an 8GB packet buffer with virtual output queues per port to avoid head-of-line blocking. A quad-core x86 CPU with 8GB of system memory runs Arista EOS. This SKU uses front-to-rear airflow with two 745W AC hot-swap power supplies in a 1+1 configuration and four N+1 hot-swap fans, with typical draw of 324W and a maximum of 499W.

QSFP+ ports accept 40GBASE optics and AOC, plus 4x10G breakout cabling. QSFP100 ports accept 100GBASE optics and cables, plus 25G breakout. Minimum EOS is 4.17.1.
