GeoCluster - Windows from here to Timbuktu
Double-Take Software - which was founded to provide data replication for servers and their applications - has been transforming itself into a workload optimization and high availability software vendor. And like everyone else, Double-Take is trying to get into the virtualization game - not just to make money, but because servers are being virtualized and their virtual machines need a lot of the same resiliency that was originally provided for physical servers.
Like other geographic replication tools, Double-Take's GeoCluster software uses an IP network link to link source and target servers together, replicating data asynchronously. With this asynchronous link, servers can be geographically dispersed, and data replication can still happen over relatively-low-bandwidth, long-distance links - usually T1 lines among Double-Take's customer base.
