Information technology — Data centre facilities and infrastructures — Part 3: Power distribution (Adopted ISO/IEC TS 22237:2018, first edition, 2018-05)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This document addresses power supplies to, and power distribution within, data centres based upon the criteria and classifications for availability, physical security and energy efficiency enablement within ISO/IEC TS 22237-1.
This document specifies requirements and recommendations for the following:
a) power supplies to data centres;
b) power distribution systems within data centres;
c) facilities for both normal and emergency lighting;
d) equipotential bonding and earthing;
e) lightning protection;
f) devices for the measurement of the power consumption characteristics at points along the power distribution system and their integration within management tools.
Safety and electromagnetic compatibility (EMC) requirements are outside the scope of this document and are covered by other standards and regulations. However, information given in this document may be of assistance in meeting these standards and regulations.
Conformance of data centres to the present document is covered in Clause 4.
