Description

The Arista 7280R3A is a fixed 1RU data centre switch router built for leaf and spine roles, internet border and peering, enterprise CDN backbones and data centre interconnect. It combines deep buffers with FlexRoute hardware routing, so it can carry large route tables while absorbing bursts of mixed real-time, multicast and storage traffic.

This DCS-7280CR3A-32S-FLX-R delivers 28 x 100GbE QSFP ports plus 2 x 400GbE QSFP-DD ports, with breakout support up to 56 x 25/10G interfaces. Throughput is 3.6 Tbps (7.2 Tbps full duplex) at 1.35 Bpps, with a 4 GB packet buffer and latency from 3.8 us. It is the FLX licence version, covering routing up to 2M routes, EVPN, VXLAN, segment routing and advanced MPLS. Airflow is rear-to-front, and it has dual hot-swap AC power supplies in a 1+1 arrangement with three hot-swap fans (N+1). Typical draw is 302 W and maximum is 481 W.

The 400G QSFP-DD ports support 400GBASE-SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR optics, as well as AOC and CR8 cabling, and can run in 200G and breakout modes. The 100G QSFP ports support 100GBASE-SR4, XSR4, SWDM4, SRBD, LR and LR4.
