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 Business Continuity Clustering (BCC), you can configure BCC to use virtual IP addresses for BCC-enabled resources as an alternate approach to assigning secondary IP addresses to resources.
