PUE

PUE is an industry accepted ratio for the measurement of the effective usage of electrical power in a Data Centre Facility and is represented by the quotient:

Total Facility Power Load

IT Equipment Power Load

The reciprocal of PUE expressed as a percentage is known as the Data Centre infrastructure Efficiency - DCiE and is represented by the quotient:

PUE

Efficient power usage needs careful consideration in the initial design and planning stages of a data centre facility and Engineers at Galileo believe PUE to be fundamental in controlling the operational costs over the lifetime of the facility and have developed the dynamic PUE calculator as an essential tool to assist in assessing optimal operational costs, coupled with the effect of design decisions and overall costs, in the selection of alternative environmentally friendly plant and their subsequent effect on PUE
