Information technology - Data centre facilities and infrastructures - Part 3: Power distribution

ISO/IEC · ISO/IEC JTC 1

The power distribution part of the ISO/IEC 22237 series; the counterpart of EN 50600-2-2, covering power supply to and distribution within the data centre against the Part 1 classes.

Overview

ISO/IEC 22237-3:2021 is the counterpart of EN 50600-2-2. It specifies requirements for power supplies to data centres and for power distribution to all equipment inside them. The requirements are structured around the availability, physical security and energy-efficiency-enablement classes defined in Part 1. Its scope includes telecommunications infrastructure bonding and lightning protection. It also covers measurement devices for power consumption and power quality along the distribution path, and their integration in management tools.

This shows that metering points need to be considered at design stage if energy efficiency is to be monitored. The exclusions are explicit: use of the data centre's stored energy or alternate sources by the grid (grid services) is out of scope, as are safety and EMC requirements, which are covered by other standards and regulations. The standard therefore does not replace electrical safety legislation; it complements it.

Edition 1 was published on 2021-10-05, runs to 35 pages and replaces ISO/IEC TS 22237-3:2018. The standard is paid; this record is built only from the publisher's public catalogue abstract and product metadata, and the full text was not read. The scope boundary therefore shows the design team in advance which subjects must be verified against other standards.

Key points

  1. Specifies requirements for power supplies to data centres and power distribution to all equipment.
  2. Counterpart of EN 50600-2-2; structured around the Part 1 availability, physical security and energy-efficiency-enablement classes.
  3. Covers telecommunications infrastructure bonding and lightning protection.
  4. Covers measurement devices for power consumption and power quality along the distribution path and their integration in management tools.
  5. Use of data centre stored energy or alternate sources by the grid is out of scope.
  6. Safety and EMC requirements are out of scope (covered by other standards and regulations).
  7. Edition 1 published 2021-10-05, 35 pages; replaces ISO/IEC TS 22237-3:2018.

Using it in design

  • In the single-line editor, validate topology against the selected availability class (single path, redundant components, multiple paths, fault-tolerant).
  • Require meter points at the levels needed for the chosen energy-efficiency granularity.
  • Flag designs without lightning protection or telecom bonding entries.
  • Verify safety and EMC requirements from the other applicable standards and regulations, not from this standard.
