Kw per rack calculator. The phase current i in amps a is equal to 1000 times the power p in kilowatts kw divided by square root of 3 times the power factor pf times the line to line rms voltage v l l in volts v. Based on this cost curve this paper proposes that the optimal average density per rack is 5 8 kw per rack. There are some significant. Rack unit calculator grid.

Equates to somewhere between 3 and 5 kw per cabinet.

The tool provides a power estimate. The middle of this range or 4 kw per cabinet may seem reasonable as it is a typical power density measured in existing data centers today.

To begin to calculate your maximum kw per rack you will first need to use the number of racks you already determined or you can calculate maximum number of racks you will be using.

Do this by taking the usable floor space for the data center and dividing it by the amount of floor space each rack takes up which will depend on your aisle arrangement. I a 1000 p kw 3 pf v l l v.

E kwh day p w t h day 1000 w kw. Such information perfectly complements the provisioning task which this 3 phase capacity tool enables. Energy consumption calculation the energy e in kilowatt hours kwh per day is equal to the power p in watts w times number of usage hours per day t divided by 1000 watts per kilowatt. When designing for total server power consumption a kw per rack approach is more useful than watts per square foot which hasn t been a valid measurement for years.

Cisco ucs power calculator information the contents of this tool are based on public information as of july 31 2013. Our devices provide billing grade accurate power information amps kwh voltage power factor kva kw for every cabinet and in many models for every power supply in every cabinet.
