ANSI∕TIA-942-2005美国数据中心电信基础设施标准（英文版）.pdf简介：
ANSI/TIA-942-2005是美国电信工业协会（Telecommunications Industry Association, TIA）制定的一种数据中心电信基础设施标准。这个标准的主要目的是为数据中心的电信基础设施设计、建设和维护提供一个行业认可的指导性框架。它详细规定了数据中心的电信设备、电缆布线、电源供应、网络连接、安全和物理安全等方面的要求。
该标准涵盖了数据中心的各个方面，包括但不限于： 1. 数据中心的位置和物理设计：考虑地震、洪水、火灾等潜在风险。 2. 基础设施：包括电力供应、冷却系统、网络设备和数据通信设施等。 3. 安全措施：如访问控制、视频监控、防火和防入侵等。 4. 数据备份和恢复：保证在灾难发生时能够快速恢复数据和业务运行。 5. 网络设计：包括网络拓扑、带宽需求、网络性能和冗余性等。
TIA-942-2005标准对于保证数据中心的高效、安全和可靠性具有重要意义，是数据中心建设和运营的重要参考依据。
