摘要
根据GB 50174-2017、TIA 942、Uptime Institute中对2N、DR、RR电气系统不同保障等级可靠性的冗余备份要求,分析数据中心常见的冗余系统,并结合工程案例指出在成熟系统上增设不必要的环节所存在的隐患。
The common redundant systems in the data center are analyzed according to the requirements for the redundant backup of reliability of the electrical systems with different security grades such as 2N, DR and RR specified in GB 50174-2017, TIA 942 and Uptime Institute, and the existing hidden dangers located at the unnecessary links of the mature systems are pointed out combined with a project case.
