Description

The Arista 7280R3 is a 1RU fixed data-centre and service-provider switch router with 32 x 100G QSFP100 ports and 4 x 400G OSFP ports. It suits data-centre spine and leaf, internet peering and interconnect, inter-DC networking, carrier edge VPN and EVPN services, and carrier core transport.

This SKU is the expanded-memory (-M) build with the FLX software licence, front-to-rear airflow and 2 x AC power supplies. It delivers 4.8 Tbps (9.6 Tbps FDX) of wire-speed throughput and 2 Bpps of packet forwarding, with latency from 3.8 us. It carries an 8 GB packet buffer with Virtual Output Queues per port, 64 GB of system memory and a quad-core x86 CPU. The FLX licence covers full routing up to 2M routes, EVPN, VXLAN, segment routing and advanced MPLS LER/LSR with traffic engineering.

The ports accept QSFP100 optics and cables, 40G QSFP+ and 25G/50G breakout, with OSFP modules on the 400G ports. Power is supplied by two hot-swap PWR-1011 1000W supplies in a 1+1 arrangement, cooled by three hot-swap fans in an N+1 arrangement.
