1.5.1 Business Continuity Clusters
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.
1.5.2 Cluster Resources
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.
1.5.3 Landing Zone
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.
1.5.4 BCC Drivers for Identity Manager
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 6.1.1, “Configuring the Identity
Manager Drivers and Templates,” on page 68 .
