Description

The Arista 7280R3A Series is a fixed 2RU deep-buffer switch built for data centre leaf and spine roles, internet peering and routing-heavy edge deployments. This model runs Arista EOS and suits cloud and content delivery, service provider, IP storage and Data Center Interconnect designs where large buffers and internet-scale routing tables matter.

The front panel provides 48 x 100G QSFP ports and 6 x 400G QSFP-DD ports. With breakout, the platform scales to up to 12 x 200G, 68 x 100G, or 114 x 50G, 25G or 10G ports, and 54 x 40G ports. L2/3 throughput is 7.2 Tbps (14.4 Tbps full duplex) with a forwarding rate of 2.7 Bpps, latency from 3.8 usec and an 8 GB total system buffer. Typical system power draw is 388 W, with front-to-rear airflow and AC or DC power supply options. This SKU carries the FLX software licence tier.

The QSFP ports take 100G optics, and the QSFP-DD ports take 400G, 200G or 100G optics. The switch is managed through Arista EOS and CloudVision, with Sync-E and PPS/10M/ToD timing support.

FAQs

Q: What does the FLX licence on this SKU refer to?
A: The -FLX suffix indicates this SKU is the FLX software licence bundle for the 7280R3A platform. Check Arista's FLX licensing documentation for the exact feature entitlements.

Q: What optics do the ports accept?
A: The 48 QSFP ports take 100G optics, and 40G, 50G, 25G or 10G through breakout or adapters. The 6 QSFP-DD ports take 400G, 200G or 100G optics.

Q: What airflow and power options does it support?
A: Airflow is front to rear, and both AC and DC power supplies are supported. Typical system power draw is 388 W.

Q: What is the buffer size and why does it matter?
A: The switch has an 8 GB total system buffer. Deep buffers help absorb bursts and keep forwarding lossless in storage, content delivery and Data Center Interconnect traffic.

Q: How is it managed?
A: It runs Arista EOS and is supported by CloudVision, with ZTP, VXLAN, LANZ and Accelerated sFlow available.
