Description

The Arista 7280R3K DCS-7280CR3K-32D4 is a 1RU fixed-configuration data centre and service-provider switch router built for large-scale layer 2 and layer 3 cloud designs, overlay networks, internet peering, inter-DC interconnect and carrier edge and core roles. It runs Arista EOS and pairs deep packet buffers with a large routing table.

The front panel provides 32 x 100GbE QSFP100 ports and 4 x 400GbE QSFP-DD ports, with throughput of 4.8 (9.6) Tbps FDX, a forwarding rate of 2 Bpps and latency from 3.8 us. As a 7280R3K variant it supports over 5M IPv4 routes, and it includes 8 GB of packet buffer memory, a quad-core x86 CPU, 64 GB of system memory and a 120 GB SSD. This SKU is the configurable fans and PSU variant, so power supplies and fan trays are selected to suit the airflow direction required.

The 400G ports support 400G, 200G, 100G, 50G and 25G modes with a range of optics and DAC/AOC cables, while the 100G ports support 100G, 50G, 40G (QSFP+) and 25G/10G breakout modes. It accepts PWR-1011 hot-swap power supplies in 1+1 redundancy and FAN-7011H fan trays in an N+1 arrangement.
