another resource group consisting of a post office and its POA, and a third resource group for
WebAccess, each resource group could be configured to fail over separately to different nodes in the
cluster.
failback: The process of returning resources and resource groups to their original node after the
situation causing the failover has been resolved. For example, if a POA and its post office fail over
to another node in the cluster, that resource group can be configured to fail back to its original node
when the problem is resolved.
shared disk system: The hardware housing the physical disks that are shared among the nodes in
the cluster. The C: drives in the clustered nodes are not part of the shared disk system. Each C: drive
belongs to its own server.
storage area network (SAN): The clustered nodes together with their shared disk system and
shared physical disks.
