Description

The 7280R is Arista's deep-buffer data centre switch router family, and this 7280QR-C72M model is built for leaf and edge deployments that need dense 40G and 100G connectivity with large packet buffers. It runs Arista EOS, giving data centre teams a single software image across Arista platforms.

This 2RU unit provides 72 QSFP ports, made up of 56 QSFP+ 40GbE ports and 16 QSFP100 ports. Port combinations extend to 16x 100GbE, 32x 50GbE, 64x 25GbE or 160x 10GbE, with breakout where supported. Switching throughput is 6.4 Tbps with 2.88 Bpps forwarding, latency from 3.8 microseconds and 16 GB of packet buffer memory. The M variant adds the expanded memory and SSD option, and the -F suffix denotes front-to-rear airflow, so confirm it matches your rack airflow design.

The QSFP+ ports accept 40GbE optics and DACs, and the 16 QSFP100 ports accept 100G optics. Deep buffers with virtual output queueing suit bursty, high-fan-in traffic at the leaf or edge layer.

FAQs

Q: How many ports can run at 100GbE?
A: Up to 16 of the 72 QSFP ports run at 100GbE. The remaining ports operate as 40GbE, with breakout options to 10G, 25G and 50G where supported.

Q: What does the -F in the SKU mean?
A: The -F suffix indicates front-to-rear airflow. Check that it matches the airflow direction of your rack before ordering.

Q: What does the M variant add?
A: The M variant adds the expanded memory and SSD option over the standard 7280QR-C72. System memory is 8 GB with 16 GB optional.

Q: Which optics and cables work in the ports?
A: The QSFP+ ports accept 40GbE optics and DACs, and the 16 QSFP100 ports accept 100G optics. Breakout to 4x10G, 4x25G or 2x50G is supported where available.

Q: What software does it run?
A: It runs Arista EOS, the same single-image operating system used across Arista platforms.
