Description

The Arista 7280R3 is a 1RU fixed data centre switch router built for large-scale Layer 2 and Layer 3 cloud networks, spine and leaf and EVPN-VXLAN overlay designs, internet peering, interconnect and carrier edge VPN services. It runs Arista EOS and is managed with CloudVision.

The front panel provides 32 x 100GbE QSFP100 ports and 4 x 400GbE OSFP ports, with 4.8 Tbps of throughput (9.6 Tbps full duplex) and 2 Bpps of packet forwarding. Latency starts from 3.8 us and an 8 GB packet buffer with Virtual Output Queues avoids head-of-line blocking. This SKU has rear-to-front airflow, 2 x hot-swap AC power supplies (PWR-1011, 1+1 redundant) and 8 GB of system memory. It is listed in EOS Feature License Group 3 and requires EOS 4.22.1 or later.

The 400G OSFP ports support 400G, 200G, 100G, 50G and 25G breakout cables and optics, including 400GBASE-DR4, XDR4, FR4, LR4 and ZR. The QSFP100 ports support 100G, 40G, 50G and 25G/10G breakout.
