Description

The Arista 7280R3 DCS-7280SR3E-40YC6-M-R is a 1RU data centre switch router built for large-scale layer 2 and layer 3 cloud designs, overlay networks, virtualised or traditional enterprise data centres, internet peering, interconnect and inter-DC networking. It also suits 5G and media networks that need precision timing.

It provides 40 x 1/10/25G SFP ports and 6 x 100G QSFP100 uplinks, with 800 Gbps throughput (1600 Gbps full duplex), 600 Mpps forwarding and latency from 3.8 us. This variant adds Synchronous Ethernet (SyncE), 32 GB of system memory and a 2 GB packet buffer, and is the rear-to-front airflow model with two AC power supplies in a 1+1 arrangement.

The QSFP100 ports support 100G as well as 40G and 50G modes, and the switch accepts a wide range of 1G, 10G and 25G SFP and 40G, 50G and 100G QSFP optics and cables. It runs Arista EOS 4.28.1 or later and sits in EOS Feature License Group 2, with optional add-on licences ordered separately.
