Description

The Arista 7280R3 series DCS-7280DR3-24-M-FLX-F is a 1RU fixed data centre switch router with 24 x 400G QSFP-DD ports. It is built for data centre spine and leaf designs, Internet peering and edge routing, carrier edge VPN services, EVPN services for 5G/MEC and metro, IP storage and content delivery networks that need deep buffers and Internet-scale routing.

This SKU is the expanded-memory variant with 64GB of system memory, the FLX licence tier and front-to-rear airflow, with 2 x AC power supplies. The 24 QSFP-DD ports deliver 9.6 Tbps throughput (19.2 Tbps full duplex) and 4 Bpps, with latency from 3.8 us and a 16 GB packet buffer. Breakout options extend to 96 x 100G, 192 x 50G or 192 x 25/10G interfaces. The quad-core x86 CPU is paired with a 120 GB SSD. Power comes from two hot-swap PWR-1511 supplies in 1+1 redundancy, with three hot-swap N+1 fans (FAN-7011H).

The QSFP-DD ports accept 400G CR8, AOC, SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR optics and cables, and also support breakout to 200G, 100G, 50G and 25G as well as QSFP+ 40G modules. The switch runs Arista EOS, minimum release 4.22.2, and is managed with CloudVision.
