Description

The Arista 7280R3A is a fixed 2RU 400G data centre switch router built for large-scale leaf and spine fabrics, Internet border and peering routing, data centre interconnect and service provider edge deployments. This SKU is the non-encryption 7280DR3A-54 with front-to-rear airflow, dual AC power supplies and the FLX routing licence.

It provides 54 wire-speed 400G QSFP-DD ports plus 2 OSFP-LS ports for 400G-ZR, with 21.6 Tbps of throughput (43.2 Tbps full duplex), 8.1 Bpps forwarding and latency from 3.8 us. A 24 GB deep packet buffer with Virtual Output Queues per port helps absorb bursts and avoid head-of-line blocking. An eight-core x86 CPU with 64 GB RAM and a 120 GB SSD runs Arista EOS. The FLX licence enables full routing with up to 2M routes, EVPN, VXLAN, Segment Routing and advanced MPLS with traffic engineering and link and node protection.

It accepts 400G QSFP-DD optics and cables including 400GBASE-SR8, DR4, XDR4, FR4, LR4, PLR4, ZR, CR8 and AOC, with breakout to 200G, 100G, 50G and 25G. It is managed through CloudVision and requires EOS 4.29.1 or later.
