DCiE Calculation

Calculation of Data Centre Infrastructure Efficiency, a predominate data centre measurement metric for understanding the efficiency of how a data centre consumes energy is relatively simple. However, the collection of the data required as input to the calculation is not always as simple.

The calculation requires two main measurements; Total Facility Power and IT Equipment Power.

Total Facility Power includes the power consumed by all of the equipment included under the definition all IT Equipment Power, such as, servers, storage, switches, workstations, printers and all of the power used in the power delivery, cooling, air conditioning, UPS. Lighting and other ancillary power consumed in the data centre is also included.

IT Equipment Power includes all IT equipment used in the delivery of an application, such as, servers, storage, switches, workstations, printers and any other service delivery equipment.

Calculation of DCiE is expressed as :

For an understanding of what a DCiE means, see DCiE and other pages on this site. Use the DCiE Calculator to work your own DCiE calculation.

DCiE is a closely related metric to PUE and they can be considered as the inverse of each other.
