Eliminate the Single Point of Failure for Improved Cluster Data Protection and Disaster Recovery. GeoCluster protects clustered data using real-time data replication to provide multiple copies of application data from both nodes of the cluster on a standby server or cluster - eliminating any single point of failure. Data is synchronized using standard TCP/IP connectivity allowing the target replica to be located almost anywhere.
This video shows how to create a High Availability File Server using Double-Take Availability GeoCluster on two Windows 2008 Servers. This video also demonstrates a severe failure of the Active Node in the cluster and the rapid resumption of service.
