One deployment consideration is how the client computers reconnect to services when cluster resources fail over to a peer cluster in the disaster recovery location. Typically, the disaster recovery site is a geographically dispersed site in a different network subnet, which forces the cluster resources to use a different IP address range. In NovellĀ® Business Continuity Cluster (BCC) 1.2 for Novell Open Enterprise Server 2 SP1 Linux, you can configure BCC to act as a dynamic DNS (Domain Name System) client.
