Description

The Arista 7280R3K is a fixed 1RU data centre switch router built for leaf, spine and internet-peering roles. It pairs deep packet buffers with a large-route FlexRoute engine, which suits overlay (EVPN/VXLAN) fabrics, enterprise and cloud data centres, interconnect and service-provider edge networks.

This 7280SR3K model provides 48 x 1/10/25G SFP28 ports and 8 x 40/100G QSFP100 uplinks, with 25G and 50G breakout on the 100G ports. It delivers 2.0 Tbps (4.0 Tbps FDX) throughput and 1 Bpps forwarding, with a 4 GB packet buffer and latency from 3.8 us. The system runs Arista EOS on a quad-core x86 CPU with 64 GB of memory and a 120 GB SSD. This SKU includes the FLX software licence, uses front-to-rear airflow, and has 2 x hot-swap AC power supplies in a 1+1 redundant configuration with 2 x hot-swap fans.

The switch uses fan tray FAN-7011M and PWR-511 power supplies, requires EOS 4.25.1 or later, and is managed with Arista CloudVision.
