Description

The Arista 7280R3 is a fixed-configuration 1RU data centre switch router built for leaf and spine roles in cloud, content delivery, service provider, IP storage and data centre networks. It is also positioned for Internet peering, DCI, carrier edge VPN services, 5G and metro aggregation, and MPLS or SR-TE cores. It runs Arista EOS.

This model provides 32 x 100G QSFP100 ports and 4 x 400G OSFP ports, with 4.8 Tbps of wire-speed throughput (9.6 Tbps full duplex), 2 Bpps packet forwarding and an 8 GB deep packet buffer. Latency starts from 3.8 us. This SKU ships with front-to-rear airflow and two 1000W PWR-1011 AC hot-swap power supplies in a 1+1 redundant arrangement, with three hot-swap fans in an N+1 arrangement. Typical power draw is 535 W with a maximum of 851 W.

The OSFP ports accept 400G optics and cables including 400GBASE-SR8, DR4, XDR4, FR4, 2FR4, LR4, PLR4, ZR, AOC and CR8 DACs, with 200G, 100G, 50G and 25G breakout options. The QSFP100 ports support 40G and 100G optics, with breakouts to 25G and 50G. The switch is managed through CloudVision.
