Description

The Arista 7280CR3-32D4 is a 1RU fixed-configuration data centre switch router from the 7280R3 family. It is built for data centre spine and leaf designs, secure Internet peering, carrier edge VPN services, EVPN services for 5G/MEC, and carrier core transport using LDP, RSVP-TE and SR-TE.

The front panel provides 32 x 100G QSFP100 ports and 4 x 400G QSFP-DD ports, giving 4.8 Tbps of wire-speed throughput (9.6 Tbps FDX) and 2 Bpps of packet forwarding. An 8 GB deep packet buffer with Virtual Output Queues per port avoids head-of-line blocking, and latency starts from 3.8 us. The system runs on a quad-core x86 CPU with 8 GB of system memory, with 64 GB optional. It is supplied with standard route scale rather than the K variant, and the fans and power supplies are configurable.

It runs Arista EOS from a single binary image, with full Linux shell access, CloudVision, EVPN, LANZ microburst detection and open APIs. The 4 x 400G ports use QSFP-DD, and the 100G ports can break out to 50G and 25/10G depending on transceiver and cable support.
