Description

The Arista 7280R3A is a fixed-configuration data centre switch router aimed at high-density leaf and spine fabrics, data centre interconnect (DCI) and WAN or routing roles. This R3AM variant adds line-rate encryption, which suits secure DCI and encrypted data centre fabrics.

It provides 48 x 100G QSFP ports and 6 x 400G QSFP-DD ports, with up to 68 x 100G ports available in a breakout configuration. Wire-speed performance is 7.2 Tbps, backed by an 8 GB dynamic deep packet buffer. MACsec, IPsec and VXLANsec (TunnelSec) encryption runs at line rate on all ports. The unit uses front-to-rear airflow and 2 x AC power supplies, and it runs Arista EOS.

The ports accept 100G QSFP100 and 400G QSFP-DD optics and DACs. The platform also supports 400G ZR and ZR+ for dense DCI, and breakout to 10G, 25G and 50G.
