Description

The Arista 7280R3 Series 7280PR3K is a 1RU fixed data centre and service-provider switch router with 24 wire-speed 400G OSFP ports. The 'K' model carries an expanded route table of over 5M IPv4 routes, making it suited to internet peering, interconnect, inter-DC networking, enterprise data centres and carrier edge and core transport, as well as large-scale layer 2 and layer 3 cloud designs and EVPN overlay networks.

Through the 24 OSFP ports it delivers 9.6 Tbps of throughput (19.2 Tbps full duplex) and 4 Bpps of packet forwarding. A 16 GB packet buffer with Virtual Output Queues per port avoids head-of-line blocking, while 64 GB of system memory, 8 GB flash and a 120 GB SSD support the control plane. Ports can break out to 200G, 100G, 50G, 25G and 10G, up to 192 interfaces in total. This variant has front-to-rear airflow and two 1500W hot-swap AC power supplies in a 1+1 arrangement, with three hot-swap fans in an N+1 arrangement. Typical draw is 650 W and maximum is 1100 W.

The switch runs Arista EOS, minimum release 4.23.1, listed under EOS Feature Licenses Group 4. The 400G OSFP ports accept 400G CR8 DAC, AOC, SR8, DR4, XDR4, FR4, 2FR4, LR4, PLR4 and ZR optics, as well as breakout cables and 40G or 100G QSFP optics via breakout.
