Description

The Arista 7280R3K is a 1U fixed data centre switch router for large-route deployments. It suits spine and leaf fabrics, internet peering, data centre interconnect and carrier or cloud edge routing, where deep packet buffers and large routing tables matter.

This DCS-7280CR3K-32D4-FLX-R provides 32 x 100GbE QSFP100 ports and 4 x 400GbE QSFP-DD ports. It delivers up to 4.8 Tbps throughput (9.6 Tbps full duplex) and 2 Bpps, with an 8 GB packet buffer and latency from 3.8 us. The -FLX suffix denotes the FlexRoute large-route bundle, supporting over 256K routes with MPLS and VXLAN. This variant has rear-to-front airflow, 2 x hot-swap AC power supplies in a 1+1 arrangement and 3 hot-swap fans in an N+1 arrangement.

It runs Arista EOS, with 7280R3 Group 3 fixed switches using the LIC-FIX-3 family of feature licences. The 400G QSFP-DD ports accept 400G optics and cables, while the 100G QSFP ports also support 40G QSFP+ and breakout to 4x25G or 10G. Fan tray FAN-7011H and PWR-1011 power supplies apply to this platform.

FAQs

Q: What does the -FLX suffix mean on this SKU?
A: It denotes the FlexRoute large-route bundle, supporting over 256K routes with MPLS and VXLAN on the 7280R3K platform.

Q: Which operating system and licensing does it use?
A: It runs Arista EOS. 7280R3 Group 3 fixed switches use the LIC-FIX-3 family of feature licences, such as LIC-FIX-3-E for Enhanced L3 and LIC-FIX-3-V for virtualisation.

Q: What power supplies does it use?
A: It uses two hot-swap AC supplies in a 1+1 redundant arrangement from the PWR-1011 family. The PWR-1011AC accepts 100-240 V AC at 50/60 Hz and delivers 1100 W output.

Q: Which optics work in the 400G ports?
A: The 4 QSFP-DD ports accept 400G QSFP-DD optics and cables. The 100G QSFP ports also support 40G QSFP+ and breakout to 4x25G or 10G.

Q: How does the -R airflow variant differ from others?
A: The -R variant moves air rear to front, so the port side is the hot aisle. Choose it to match your rack airflow design.
