If you're running a datacentre, you are accountable for the amount of energy the facility consumes and how efficient that consumption is.
PUE Power Usage Effectiveness
Power usage effectiveness (PUE) is a measurement of how efficiently power is used in a datacentre, It's the ratio of total power (ie CRAC units, chillers, UPS, PDUs, lighting, monitoring equipment etc) consumed in relation to the IT specific equipment operating in it.
Power Usage Effectiveness (PUE) and Datacentre infrastructure Efficiency (DCiE) are accepted standards proposed by the Green Grid to evaluate how energy efficient a data centre is.
How to calculate (PUE) and (DCiE)
(PUE) is expressed as a value and is calculated by taking the total facility power and dividing it by total IT power consumed.
For example a centre with a total power usage of 400KW and a total IT consumption 188kw would have a PUE value of 2.13.
DCiE) is expressed as a percentage and is calculated by taking the total IT power consumed and dividing it by the total facility power consumed.
For example a centre with a total power usage of 400KW and a total IT consumption 188kw would have a (DCiE) percentage of 47%
Energy efficient outcome
Knowing and understanding these values is a key step towards improving energy efficiency within your facility.
