ISO/IEC 30134-5:2017/Amd 1:2025 PDF

Overview

ISO/IEC 30134-5:2017/Amd 1:2025 is an amendment to the international standard focused on key performance indicators (KPIs) for data centres, specifically addressing IT Equipment Utilization for servers (ITEUsv). This amendment refines the definition and scope of server utilization metrics by emphasizing the use of CPU utilization alone as the core indicator. It excludes servers where auxiliary processing accelerators (APAs)-additional compute devices that handle parallelized workloads alongside CPUs-perform the majority of computation.

Produced by ISO/IEC JTC 1, SC 39 on Sustainability, IT, and Data Centres, this document supports the monitoring and reporting of server utilization, helping to optimize the energy efficiency and operational performance of data centres worldwide. The amendment clarifies that ITEUsv is intended for data reporting purposes only and should not be used for regulatory enforcement within data centre management.

Key Topics

• IT Equipment Utilization for Servers (ITEUsv): Focus on measuring server CPU utilization exclusively, delivering a standardized metric for assessing server workload within data centres.

• Auxiliary Processing Accelerators (APAs): Defined as additional compute devices managing parallelized workloads; servers relying mainly on APAs are excluded to maintain consistent CPU-centric measurement.

• Scope Clarification: The amendment explicitly limits the application of ITEUsv to servers primarily utilizing CPUs, increasing metric accuracy and relevance.

• Non-Regulatory Use: ITEUsv is recommended solely for monitoring and reporting purposes, guiding data centre operators without serving as a binding regulatory metric.

• Terminology and Definitions: Updates the standard with new terms and abbreviations like APA to reflect evolving server technologies.

Applications

• Data Centre Performance Monitoring: Enables operators to assess and report server CPU utilization as a critical KPI, supporting capacity planning and performance optimization.

• Energy Efficiency Management: Facilitates tracking of IT equipment usage related to server workloads, contributing to energy-saving strategies and sustainability goals.

• Benchmarking and Reporting: Provides a consistent and internationally recognized metric for annual or periodic data centre reports on server utilization.

• Operational Planning: Helps IT managers identify underutilized servers, improve resource allocation, and reduce operational costs.

• Technology Assessments: Assists decision-makers in evaluating server equipment investments by providing utilization insights specific to CPU workloads.

Related Standards

• ISO/IEC 30134 Series: A suite of standards covering key performance indicators for data centres, including metrics on energy usage and infrastructure performance.

• ISO/IEC 21836:2020: Defines the Server Energy Effectiveness Metric, referenced in this amendment, offering complementary guidance on server energy efficiency.

• ISO/IEC Directives, Part 1 and 2: Provide procedural rules for the development, maintenance, and editorial practices for ISO standards like ISO/IEC 30134-5.

• Data Centre Sustainability Standards (SC 39): Covers broader requirements and metrics supporting sustainable IT and data centre operations.

This amendment to ISO/IEC 30134-5 reinforces the importance of precise and practical server utilization metrics centered on CPU activity. It supports data centre operators globally in achieving transparent and effective performance reporting, aiding both operational excellence and environmental sustainability initiatives.
