Kilowatt per rack (kW/rack) is the power assigned to a server rack in a data center. It is measured in kilowatts (kW) and represents the total power needed for all IT equipment in that rack. Colocation providers offer different power levels: Power density depends on server type, workload, and cooling efficiency.
Selecting the right dimensions ensures your equipment fits and operates efficiently. Rack height is typically measured in rack units (RU), with one RU equating to 1.75 inches. The most common height for server racks in data centers is 42U, which translates to a height of 73.5 inches.
