Description

The Arista 7280RA is a 1RU fixed-configuration data centre switch router from the 7280R Series, built for data centre leaf and spine roles, internet peering and inter-DC interconnect. It pairs deep packet buffers with large routing tables, so it suits overlay and VXLAN designs as well as large-scale Layer 2 and Layer 3 cloud networks.

The front panel provides 36 QSFP ports, made up of 24 x 40GbE QSFP+ and 12 x 100GbE QSFP100. Port modes scale to 12 x 100GbE, 24 x 50GbE, 36 x 40GbE, 48 x 25GbE or 120 x 10GbE. The switch delivers 3.84 Tbps of full-duplex throughput and a 1.44 Bpps forwarding rate, with latency from 3.8 us and an 8 GB packet buffer. This SKU is the rear-to-front airflow model with two 747W AC hot-swap power supplies in a 1+1 arrangement, typically drawing 419W and up to 570W.

It runs Arista EOS 4.19.0 or later and is managed with CloudVision. The 24 QSFP+ ports take 40GbE optics and cables, while the 12 QSFP100 ports support 100GbE and 40GbE, with 50GbE and 4x10GbE or 4x25GbE breakout modes available.

FAQs

Q: What does the -R suffix on this model mean?
A: The -R suffix denotes rear-to-front airflow, where air flows from the fan side to the port side of the switch.

Q: Which optics fit the ports on this switch?
A: The 24 QSFP+ ports take 40GbE QSFP+ optics and cables. The 12 QSFP100 ports support 100GbE and 40GbE, plus 50GbE and 4x10GbE or 4x25GbE breakout modes.

Q: What power does this switch need?
A: It uses two 747W AC hot-swap power supplies in a 1+1 redundant arrangement, accepting 100-240V AC at 50/60Hz through a C14 inlet. Typical draw is 419W and maximum is 570W.

Q: What software does it run?
A: It runs Arista EOS as a single binary image, with a minimum of EOS 4.19.0, and is managed with CloudVision.

Q: How does this SKU differ from other 7280QRA-C36S variants?
