1、Client nodes run front end applications that retrieve data from the services provided by the
server nodes. Client nodes can run HACMP software to monitor the health of the nodes,
and to react to failures.
  这一句当中描述Client端从服务器节点运行数据校验的前端应用服务， 并且Client端可以运行HACMP软件 来检测节点的状态。
始终有些不太清楚，这里的Client端到第描述的是什么意义的Client？看这段的描述并不是严格意义上的客户端而是HACMP的客户端？
这样理解对不对？
2、A full high availability solution typically includes the client machine that uses services
provided by the servers. Client nodes can be divided into two categories: naive and intelligent.
• A naive client views the cluster as a single entity. If a server fails, the client must be
restarted, or at least must reconnect to the server.
• An intelligent client is cluster-aware. A cluster-aware client reacts appropriately in the face
of a server failure, connecting to an alternate server, perhaps masking the failure from the
user. Such an intelligent client must have knowledge of the cluster state.
  这段我更头晕。。 A naive client 与An intelligent  到底应该怎样理解呢？

  另外，既然有这两种Client端，An intelligent 得优势明显高于A naive client ，那还有人选择A naive client 么？

先不用管它。

直接向后看了。。。。

？？？？
