Description

The Arista 7280R3 is a 1RU fixed-configuration data centre switch router built for spine, internet edge, peering and WAN roles where deep packet buffers and large route tables matter. This K series model runs Arista EOS and pairs the FlexRoute engine with 8GB of packet buffer.

It provides 32 x 100GbE QSFP100 ports and 4 x 400GbE OSFP ports, with 4.8 Tbps of wire-speed performance and latency from 3.8 us. The large-route (K series) engine supports over 2.5M IPv4 routes, and the platform handles 768K MAC addresses and 768K IPv4 and IPv6 host routes. This SKU is the FLX variant with configurable fans and power supplies, front-to-rear airflow and two AC power supplies. Typical power draw is 650 W, with a maximum of 1100 W.

The 100G ports also support 25G, 40G and 50G speeds, and the 400G OSFP ports support 400G or 4 x 100G breakout. The minimum EOS release is 4.22.2.
