After you set the BMC address on a node, you have remote powercontrol, which makes life easier when configuring the cluster.
在节点上设置了BMC地址之后，就可以进行远程电源控制，这样的话就可以更加轻松地配置集群了。

If you have no hardware powercontrol (no BMC IP address is set), start by flashing the BMC firmware, which enables you to set the IP address at the same time.
The new version also will have Enhanced PowerControl, which is meant to reduce the number of disconnects that are caused by things like putting the cell phone in a pocket.
