|Oracle Solaris Cluster System Administration Guide Oracle Solaris Cluster 4.0|
This chapter provides the following information about administering a global cluster and a zone cluster, and includes procedures for using Oracle Solaris Cluster administration tools:
All procedures in this guide are for use on the Oracle Solaris 11 Operating System.
A global cluster is composed only of one or more global-cluster voting nodes. A global cluster can also include solaris brand, non-global zones that are not nodes, but high-availability containers (as resources) that are configured with the HA for Zones data service. A zone cluster requires a global cluster. For general information about zone clusters, see the Oracle Solaris Cluster Concepts Guide.
A zone cluster is composed of one or more solaris brand, voting nodes. All nodes of a zone cluster are configured as non-global zones of the solaris brand that are set with the cluster attribute. No other brand type is permitted in a zone cluster. You can run supported services on the zone cluster similar to a global cluster, with the isolation that is provided by Oracle Solaris zones. A zone cluster depends on, and therefore requires, a global cluster. A global cluster does not contain a zone cluster. A zone cluster has, at most, one zone cluster node on a machine. A zone-cluster node continues to operate only as long as the global-cluster voting node on the same machine continues to operate. If a global-cluster voting node on a machine fails, all zone-cluster nodes on that machine fail as well.
