一旦这了解了，计算该集群的可用性的公式相对来说就容易知道了，但是可能计算起来很枯燥。
Once this is known, the formulae required to calculate the availability of the cluster are relatively well known, but can be rather tedious to calculate.
性能数据源(PDS)是性能或可用性数据的来源，这些数据对于反映组件的相对健康状况非常有用。
A performance data source (PDS) is a source of performance or availability data that is useful as a measurement to reflect a component's relative health.
应用程序要求相对较高的集成数据可用性的情况可能不适合应用这种模式。
Situations in which applications require a relatively high degree of availability of the integrated data may not be good candidates to apply this pattern.
