The key concepts in this section can help you understand how Business Continuity Clustering manages your business continuity cluster.
A cluster of two to four Novell Cluster Services clusters that are managed together by Business Continuity Clustering software. All nodes in every peer cluster are running the same operating system.
A cluster resource is a cluster-enabled shared disk that is configured for Novell Cluster Services. It is also BCC-enabled so that it can be migrated and failed over between nodes in different peer clusters.
The landing zone is an eDirectory context in which the objects for the Virtual Server, the Cluster Pool, and the Cluster Volume are placed when they are created for the peer clusters. You specify the landing zone context when you configure the Identity Manager drivers for the business continuity cluster.
Business Continuity Clustering requires a special Identity Manager driver that uses an Identity Vault to synchronize the cluster resource configuration information between the peer clusters. If the peer clusters are in different eDirectory trees, an additional BCC driver helps synchronize user information between the trees. For information, see Section 8.0, Configuring the Identity Manager Drivers for BCC.
