Description

The 7280CR3K-32D4 is a 1RU fixed data centre switch router from the Arista 7280R3 Series (7280R3K family). It is built for spine, data centre interconnect (DCI), WAN and service-provider edge roles, as well as deep-buffer aggregation in storage fabrics and congestion-heavy environments.

This SKU provides 32 x 100G QSFP100 ports and 4 x 400G QSFP-DD ports, delivering 4.8 Tbps of wire-speed throughput and 2 Bpps forwarding with latency from 3.8 us. A deep packet buffer and the FlexRoute engine support the full internet routing table in hardware. Airflow is front-to-rear (-F) and the unit is fitted with 1+1 hot-swap 1500W AC power supplies and N+1 hot-swap FAN-7011H fan modules. It runs Arista EOS with Feature License Group 4 listed for the platform.

The 400G QSFP-DD ports support breakout to 4 x 100G, and the 100G QSFP ports support 10/25/40/50/100G modes via breakout or adapters. The 7280R3K variant requires EOS 4.23.1 or later and is managed with Arista CloudVision.

FAQs

Q: What software does this switch run and what licence group applies?
A: It runs Arista EOS. The datasheet lists EOS Feature License Group 4 for this platform. The 7280R3K variant requires EOS 4.23.1 or later.

Q: What power supplies does this model use?
A: It uses 1+1 redundant hot-swap 1500W power supplies, AC on the -F SKU, with N+1 hot-swap FAN-7011H fan modules. Typical draw is 650W and maximum draw is 1100W.

Q: Can the 400G ports run at lower speeds?
A: Yes. The 4 x 400G QSFP-DD ports support breakout to 4 x 100G. The 32 x 100G QSFP ports support 10/25/40/50/100G modes via breakout or adapters.

Q: What does the -F suffix mean on this SKU?
A: The -F suffix denotes front-to-rear airflow with AC power supplies, which suits hot-aisle and cold-aisle rack layouts where ports face the cold aisle.

Q: Which roles is this switch designed for?
A: It is designed for universal spine, data centre interconnect, WAN and service-provider edge, and deep-buffer aggregation, including storage fabrics and congestion-heavy environments.
