What is Power Usage Effectiveness (PUE)?

Power Usage Effectiveness (PUE) is a way of determining how efficiently a data centre uses energy. PUE measures how much energy is used to power the IT equipment in a data centre in comparison with how much energy it takes to run the facility (i.e cooling, lighting etc.). PUE is determined by dividing the amount of power entering a data center by the power used to run the computer infrastructure within it. A PUE survey will give a data centre a PUE of 1 or above. According to the Uptime Institutes’ 2014 Data Centre Survey, the average PUE for respondents’ largest data centres is 1.7.

Data centre managers are becoming increasingly aware of the need to reduce carbon emissions. This, alongside rising energy costs and an increased demand for servers to host more data, means finding out the efficiency of data centres is becoming a priority.
