Description

The 7280R3 is a fixed 1RU data centre switch router from Arista's 7280R3K family, built for leaf, spine and internet-peering roles. It suits cloud and data centre fabrics, interconnect and inter-DC networks, service provider and content delivery networks, and large L2/L3 designs using EVPN/VXLAN overlays.

It provides 32 x 100G QSFP100 ports and 4 x 400G QSFP-DD ports, with 4.8 Tbps of throughput (9.6 Tbps full duplex), a 2 Bpps forwarding rate and latency from 3.8 us. An 8GB deep packet buffer supports lossless forwarding of mixed real-time, multicast and storage traffic. This R3K variant carries the large-route FlexRoute scale, and the -R suffix denotes rear-to-front airflow with 2 hot-swap 1+1 redundant AC power supplies. It runs Arista EOS and sits in EOS Feature License Group 3.

The 400G QSFP-DD ports accept 400GBASE-CR8, AOC, SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR, along with 200G and 100G breakout cables and optics. The QSFP100 ports support 100G, 50G, 40G, 25G and 10G optics and breakouts. Minimum EOS release is 4.27.2.

FAQs

Q: Which EOS licence group does this switch fall under?
A: It is in Arista EOS Feature License Group 3. Optional LIC-FIX-3- licences cover Enhanced L3, Virtualization, EOS Extensions/Security, Monitoring & Automation and FlexRoute options.

Q: What power supplies does it use?
A: It uses two hot-swap PWR-1011 AC power supplies in a 1+1 redundant arrangement. Each delivers 1000W from 200-240V AC at 50/60Hz via an IEC C14 inlet.

Q: What airflow direction does the -R model have?
A: The -R suffix denotes rear-to-front airflow, using three hot-swap N+1 FAN-7011H fan trays. Plan rack airflow so cold air enters at the rear.

Q: What optics can I use in the 400G QSFP-DD ports?
A: They support 400GBASE-CR8, AOC, SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR, plus 200G and 100G breakout cables and optics.

Q: How does this model differ from the standard 7280R3?
A: This is the R3K large-routes variant, extending FlexRoute scale to over 5M IPv4 routes. It also needs a minimum EOS release of 4.27.2.
