建立容错系统的第一步是建立系统冗余。在数据中心基础设施中最先配置的是UPS,接下来通常是一般的部件,例如发电机、空调以及电池系统。再下一步就是确保合理地分配冗余——但这一步经常被忽视。人们常常忽略了一点,这就是配电系统中缺少冗余。从UPS引出的线经常没有冗余,为关键设备供电的配电 The first step in establishing a fault-tolerant system is to establish system redundancy. The first to be configured in the data center infrastructure is the UPS, followed by the usual components, such as generators, air conditioners, and battery systems. The next step is to ensure that redundancy is rationally assigned - but this step is often overlooked. One often overlooks the lack of redundancy in power distribution systems. The lines drawn from the UPS are often not redundant, powering the critical equipment
