WebSphere Application Server运行时使用一个类似的策略帮助区分可能与给定故障情形或缺陷有关的各种内部组件。
The WebSphere Application Server runtime USES a similar strategy to help distinguish between the various internal components that could be involved in a given failure scenario or defect.
非 IP 网络：例如 RS232（为了确保即使在发生网络故障的情况下 PowerHA 也能够区分网络故障和节点故障，需要非 IP 网络）
Non-IP networks: An example is RS232 (this is needed to make sure that even if the network goes down, PowerHA is capable of differentiating between network failure and node failure)
