Microsoft Windows Server 2008 includes new features that provide significant improvements for managing clusters in multi-site architectures. For example, Windows Server 2008 Failover Clustering removes the dependency of having all cluster nodes on the same subnet. However, improvements to Failover Clustering do not yet provide a way to replicate the shared data used by a cluster which is truly the "last mile" in terms of building multi-site cluster architectures. GeoCluster provides a way to efficiently replicate these data changes and allow cluster nodes to quickly restore application services after a failure. Together, Windows Server 2008 Failover Clustering and GeoCluster from Double-Take Software provide the ultimate geographically-distributed application recoverability solution for clustered applications.
