Description

The Arista 7280R3K is a fixed 1RU data centre switch router built for large-scale routing in spine and leaf fabrics, internet peering, carrier edge VPN services and inter-DC interconnect. This 7280CR3K-36S model provides deep buffers and the FlexRoute engine, so it can hold a full internet routing table in hardware.

Port density is 28 x 100G QSFP100, 6 x 200G QSFP200 and 2 x 400G QSFP-DD, with throughput of 2.4 Tbps (4.8 Tbps full duplex) and forwarding of 1 Bpps. Latency starts from 3.8 us, backed by a 4 GB packet buffer. A quad-core x86 CPU, 64 GB of system memory and a 120 GB SSD run Arista EOS. This SKU carries the FLX licence tier, uses front-to-rear airflow and has two hot-swap AC power supplies in a 1+1 arrangement.

It accepts 400G QSFP-DD, 200G QSFP200 and 100G QSFP100 optics and cables, with 40G, 50G and 25/10G breakout options. Spare fans are FAN-7011M-F for front-to-rear airflow, and the switch is managed with CloudVision.
