Description

The Arista 7280R3K is a 1RU fixed data centre switch router built for data centre spine and leaf roles, internet peering and interconnect, inter-DC networking, and service provider or cloud-scale routing where large routing tables and deep buffers are needed. As a 7280R3 series model, it uses the FlexRoute engine to scale routing tables beyond 5M routes.

The front panel provides 32 x 100G QSFP100 ports and 4 x 400G OSFP ports, delivering 4.8 Tbps of throughput (9.6 Tbps full duplex) and 2 Bpps forwarding with latency from 3.8 us. An 8 GB packet buffer with virtual output queueing helps avoid head-of-line blocking. This SKU has the eight-core x86 CPU with 64 GB of system memory and a 120 GB SSD. It ships with 2 x hot-swap AC power supplies in a 1+1 configuration and 3 x hot-swap fans, with rear-to-front airflow.

The QSFP100 ports accept 100G optics and cables, and can run 40G using QSFP+ or breakout to 50G, 25G and 10G. The OSFP ports support 400G. The switch runs Arista EOS and is managed with Arista CloudVision.
