Description

The Arista 7280R3K is a 1RU fixed data centre switch router built for internet peering, inter-DC interconnect and spine or leaf roles where deep buffers and large routing tables matter. It pairs high-density 100G with four 400G uplinks in a single front-to-rear airflow chassis.

This SKU provides 32 x QSFP100 ports and 4 x OSFP 400GbE ports, with 4.8 Tbps throughput (9.6 Tbps full duplex), up to 2 Bpps forwarding and latency from 3.8 us. It has 8 GB of packet buffer, an eight-core x86 CPU, 64 GB of system memory and a 120 GB SSD. The QSFP ports support 100G, 50G, 40G, 25G and 10G with breakouts. It is the 7280R3K large-route variant with FlexRoute for very large routing tables, supplied in the FLX licence bundle.

Power is delivered by 2 x hot-swap PWR-1011 AC supplies in a 1+1 arrangement, with 3 x FAN-7011H fans in N+1. The 7280R3K models require EOS 4.27.2 or later.
