Description

The Arista 7280R3K is a fixed 1RU data centre switch router built for 100G and 400G leaf, spine and aggregation roles, as well as internet peering and carrier edge or core routing where deep buffers and large route tables are required. It belongs to the 7280R3 series and uses the large-route (R3K) profile.

It provides 32 x 100GbE QSFP100 ports and 4 x 400GbE OSFP ports, with up to 4.8 Tbps (9.6 Tbps full duplex) of throughput, 2 Bpps packet forwarding and latency from 3.8 us. An 8 GB packet buffer supports lossless forwarding under mixed real-time, multicast and storage traffic. The R3K profile supports over 5M IPv4 routes and up to 384K MAC addresses. Breakout options allow up to 96 x 25/10G interfaces. This variant has two hot-swap PWR-1011 1000W AC power supplies in a 1+1 arrangement, three hot-swap fans in an N+1 arrangement and front-to-rear airflow. It runs Arista EOS with Feature License Group 3.

The 32 QSFP ports accept QSFP100/QSFP28 and 40G QSFP+ optics, and the 4 OSFP ports accept 400G OSFP optics. Spare parts include PWR-1011 AC and DC power supplies and FAN-7011H-F or FAN-7011H-R fan modules. The switch is managed with CloudVision and Arista EOS.
