ISO/IEC 30134-5:2017 specifies the IT Equipment Utilization for servers (ITEUsv) as a Key Performance Indicator (KPI) to quantify the utilization of servers in a data centre. ISO/IEC 30134-5:2017 is intended as a KPI for improving the aggregate energy efficiency of servers in a given data centre. 

ITEUsv utilizes only CPU utilization of servers in a data centre. Servers where the majority of computation is provided by auxiliary processing accelerators (APAs) are out of scope.

ISO/IEC 30134-5:2017

a) describes the purposes of ITEUsv,

b) defines ITEUsv in a conceptual manner,

c) describes how to use ITEUsv, and

d) describes reporting of ITEUsv.
