18.2 Overview of the mutual node switching system

The mutual node switching system is a system in which two servers are configured as a 1-to-1 node switching system. The two servers run as the active nodes, and each server becomes the spare node for the other server.

This section describes an example system configuration for a mutual standby system and the flow of the node switching process. The timing for node switching and the system operations during the switching of nodes are the same as for a 1-to-1 node switching configuration. The following table lists the reference sections:
