Multiple-Site Business Continuity Cluster Solution - Novell BUSINESS CONTINUITY CLUSTERING 1.1 SP2 - ADMINISTRATION Administration Manual

Figure 1-3 shows a two-site business continuity cluster that uses storage-based data replication
between the sites. BCC uses eDirectory and Identity Manager to synchronize cluster information
between the two clusters.

1.4.2 Multiple-Site Business Continuity Cluster Solution

The multiple-site business continuity cluster is a large solution capable of supporting up to four
sites. Each cluster can support up to 32 nodes. Services and applications can do fan-out failover
between sites. Replication of data blocks is typically done by SAN hardware, but it can be done by
host-based mirroring for synchronous replication over short distances up to 10 km.
