Rated-3: Concurrently Maintainable Site Infrastructure A data center which has multiple independent distribution paths serving the ICT equipment. From a conformity point of view, it is acceptable to have one distribution path serve the ICT equipment with the second distribution path to be on standby...
2. UPTIME Institute 和TIA都使用术语Tier来表示四种不同级别的设计原则。UPTIME Institute 过去和现在仍然使用罗马数字（I，II，III，IV），而TIA则使用阿拉伯语 （1,2,3,4）；2013年以后改为 Rated/Rating（1,2,3,4） 。3, 从范围来说，UPTIME Institute 包括了电力和机械两部分；TIA-942不仅解...
TIA于2005年发布了ANSI / TIA-942标准。在2014年以后则采用了Rated/Rating 1, 2,3,4 来验证数据中心的iso认证和设施等级。 UTI Tier I-II-III-IV与ANSI / TIA-942 Rated 1-2-3-4描述的额定值完全相同。例如,UTI:TST将Tier-III定义为可并发维护(CM)数据中心,类似于ANSI / TIA-942,将Rated-3定义为可...
例如，UTI：TST将Tier-III定义为可并发维护（CM）数据中心，类似于ANSI / TIA-942，将Rated-3定义为可同时维护的数据中心。但是TST仅涵盖电气和机械（冷却），而ANSI / TIA-942还包括满足CM要求的电信要求。一个关键的区别是ANSI / TIA-942提供了更加透明和指导如何实现这一点，通过明确指出应该/可以...
Rated-2: Redundant Capacity Component Site Infrastructure A data center which has redundant capacity components and a single, non-redundant distribution path serving the ICT equipment. It has improved protection against physical events. Rated-3: Concurrently Maintainable Site Infrastructure ...
