Information technology - Data centres - Key performance indicators - Part 5: IT Equipment Utilization for servers (ITEUsv)

ISO/IEC · ISO/IEC JTC 1

ISO/IEC standard defining ITEUsv, a KPI for how well servers in a data centre are utilised.

On this page

Overview

ISO/IEC 30134-5 is the fifth part of the data centre key performance indicator (KPI) series and defines ITEUsv, a measure of server utilisation. Its purpose is to drive aggregate server energy efficiency, since an idle server keeps drawing power much as a loaded one does. Edition 1 was published on 26 October 2017 and runs to seven pages.

The method's defining feature is that it uses only server CPU utilisation. There is also a clear boundary: servers whose computation is mainly delivered by auxiliary processing accelerators (APAs) are out of scope. In GPU- or accelerator-heavy AI halls the indicator therefore gives no meaningful result and could mislead. The standard covers purpose, conceptual definition, use and reporting.

The document sits alongside ISO/IEC 30134-4 and EN 50600-4-8 as a complementary measure. The record gives no threshold or target values, so ITEUsv should be treated as a monitoring and benchmarking tool, not a compliance condition. Its limitation is that it is CPU-only and does not reflect memory, network or storage utilisation.

Key points

  1. ITEUsv is specified as a KPI for utilisation of servers in a data centre.
  2. The indicator uses only server CPU utilisation.
  3. Servers where most computation comes from auxiliary processing accelerators are out of scope.
  4. The standard covers purpose, conceptual definition, use and reporting.
  5. Edition 1 published 26 October 2017, seven pages.
  6. Related standards: ISO/IEC 30134-4 and EN 50600-4-8.

Using it in design

  • In the operations dashboard, compute ITEUsv only for CPU-centric servers.
  • Flag GPU and accelerator racks as out of scope so AI halls are not given a misleading utilisation figure.
  • Use utilisation data to derive realistic IT load profiles for cooling and UPS sizing.
