CSA Preface 

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. For brevity, this Standard will be referred to as "CSA ISO/IEC 22237-1" throughout. This Standard replaces CSA ISO/IEC TS 22237-1:19 (adopted ISO/IEC TS 22237-1:2018). The International Standard was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. 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. 

Scope 

This document: a) describes the general principles for data centres upon which the requirements of the ISO/IEC 22237 series are based; b) defines the common aspects of data centres including terminology, parameters and reference models (functional elements and their accommodation) addressing both the size and complexity of their intended purpose; c) describes general aspects of the facilities and infrastructures required to support data centres; d) specifies a classification system, based upon the key criteria of "availability", "security" and "energy-efficiency" over the planned lifetime of the data centre, for the provision of effective facilities and infrastructure; e) details the issues to be addressed in a business risk and operating cost analysis enabling application of the classification of the data centre; f) provides a reference to the operation and management of data centres. The following topics are outside of the scope of the ISO/IEC 22237 series: 1) the selection of information technology and network telecommunications equipment, software and associated configuration issues are outside the scope of this International Standard; 2) quantitative analysis of overall service availability resulting from multi-site data centres; 3) safety and electromagnetic compatibility (EMC) requirements (covered by other standards and regulations. However, information given in this document can be of assistance in meeting these standards and regulations).
