宕机时间 meaning in English

downtime

Data is at the heart of any business , and access to it should be available with minimum downtime
数据是所有业务的心脏，对数据的访问的宕机时间应该维持在最少。
But both are inert components without the heartbeat - having reliable , readily available access to that data , access with minimum downtime
但是如果没有heartbeat对这些数据具有可靠而快速的访问，且宕机时间最少那么这两者都是惰性组件。
