Description

The Arista 7280R3AK is a 2RU fixed switch router from the 7280R3A series, built for large-scale layer 2/3 cloud data centres, universal spine roles, Internet border and peering, data centre interconnect and service-provider edge networks. It runs Arista EOS with CloudVision support and is aimed at designs that need deep buffers and Internet-scale routing in a single fixed chassis.

This SKU provides 36 x 400G QSFP-DD ports, with breakout to up to 144 x 100G or 232 x 25/10G interfaces. Throughput is 14.4 Tbps (28.8 Tbps full duplex) at 5.4 Bpps, with latency from 3.8 us, 16 GB of packet buffer and 64 GB of system memory. The 7280R3AK variant adds large-scale routing of over 5M IPv4 routes with FlexRoute, plus TunnelSec and MACsec encryption on all ports. The FLX licence bundle suits designs using EVPN, VXLAN, Segment Routing and MPLS. Power is two hot-swap 2400W AC supplies in a 1+1 arrangement with front-to-rear airflow, and typical draw is 643 W.

The 400G ports accept 400GBASE-CR8 copper, AOC, SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR optics, and also support 200G, 100G, 50G and 25G breakout modes. Minimum software is EOS 4.30.0.
