Configuration node

A configuration node is a single node that manages configuration activity of the system.

If the configuration node fails, the system chooses a new configuration node. This action is called configuration node failover. The new configuration node takes over the management IP addresses. Thus, you can access the system through the same IP addresses although the original configuration node has failed. During the failover, there is a short period when you cannot use the command-line tools or management GUI.

Figure 1 shows an example of a clustered system that contains four nodes. Node 1 is the configuration node. User requests ( 1 ) are handled by node 1.
