The Arista DCS-7280PR3-24-F is a 1RU 7280R3 switch router with 24 400GbE OSFP ports. Every port is 400GbE, and breakout options reach 96 100G, 192 50G, 24 40G or 192 25G/10G interfaces.
Capacity is 9.6 Tbps (19.2 Tbps full duplex) with 4 Bpps forwarding, and latency starts at 3.8 microseconds according to Arista. A 16 GB packet buffer gives headroom for congestion in spine and interconnect roles. Route scale is profile dependent, with up to 1450K IPv4 routes in the L3 profile plus up to 1792K more using FlexRoute, and 224K MAC addresses.
Two hot-swap 1500 W PWR-1511 AC supplies are included (1+1); the PWR-1511-DC-RED is the DC option. Three hot-swap FAN-7011H-F fans provide N+1 cooling. Airflow is front-to-back (port-side intake) only, with no back-to-front version listed. Typical power is 650 W, maximum 1100 W.
The switch weighs 28 lb and measures 17.3 x 22.6 x 1.72 inches. Advanced Layer 3 features such as BGP and OSPF need an Arista Enhanced L3 license, which is not included and is available from Arista partners.
Matching spares include the PWR-1511-AC-RED power supply.
Check your rack depth, power feeds, and cold-aisle orientation before you order, since the airflow direction is set by the fans and power supplies installed.
