Description

The Arista 7280R3 (7280PR3-24) is a 1RU fixed-configuration data centre switch router with 24 wire-speed 400G OSFP ports. It is built for cloud, internet peering, inter-DC and service-provider designs that need large routing tables and deep buffering, and it runs Arista EOS.

The 24 OSFP ports deliver 9.6 Tbps of throughput (19.2 Tbps full duplex) and up to 4 billion packets per second, with latency from 3.8 us. Breakout takes the port count to as many as 96 x 100G, 192 x 50G or 192 x 25/10G, depending on the transceivers and cables used. A 16 GB packet buffer with Virtual Output Queues avoids head-of-line blocking. This SKU has configurable fans and PSU, a quad-core x86 CPU and 8 GB of system memory. Two hot-swap 1+1 PWR-1511 power supplies and three N+1 FAN-7011H fans provide redundancy, with front-to-rear airflow. Typical draw is 650 W and maximum is 1100 W.

The OSFP ports support 400G, with 100G, 50G, 25/10G and 40G (using QSFP+) available through breakout and adapters. The datasheet lists EOS feature licences as Group 4 with a minimum EOS of 4.22.2.
