The LogicalHost resource is an IP address that is active from only one virtual node at a time. The administrator can switchover the LogicalHost resource from one virtual node to another. The system automatically configures the LogicalHost resource on the node where the application uses that LogicalHost resource. Should a virtual node fail, the system will automatically move the LogicalHost resource along with the dependent application to a surviving node. The zone cluster validates the permissions of the LogicalHost when creating a LogicalHost resource and when activating a LogicalHost resource on a node. Any LogicalHost resource always stays within one zone cluster.

The SharedAddress resource is an IP address that appears to be active for the entire cluster, while in reality the IP address is hosted on one machine and the cluster distributes incoming traffic across the cluster based upon the selected load balancing policy. The system automatically changes the node hosting the IP address for the SharedAddress in case of node failure. The zone cluster validates the permissions of the SharedAddress when creating a SharedAddress resource and when activating a SharedAddress resource on a node. A SharedAddress resource operates strictly within one zone cluster.
