本文件: a） 描述了ISO/IEC22237系列要求所依据的数据中心的一般原则； b） 定义数据中心的通用方面，包括术语、参数和参考模型（功能要素及其适应范围），以解决其预期用途的规模和复杂性； c） 描述支持数据中心所需的设施和基础设施的一般方面； d） 根据数据中心计划寿命期内的“可用性”、“安全性”和“能源效率”等关键标准，指定一个分类系统，以提供有效的设施和基础设施； e） 详细说明在业务风险和运营成本分析中需要解决的问题，以便应用数据中心的分类； f） 为数据中心的运营和管理提供参考。 以下主题不在ISO/IEC？22237系列的范围内: 1） ？信息技术和网络电信设备、软件和相关配置问题的选择不在本国际标准的范围内； 2） ？对多站点数据中心产生的整体服务可用性进行定量分析； 3） ？安全和电磁兼容性（EMC）要求（由其他标准和法规涵盖。但是，本文件中提供的信息有助于满足这些标准和法规）。

This document: a) describes the general principles for data centres upon which the requirements of the ISO/IEC22237 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).
