If you are working in a clustered environment, the GeoCluster feature of Double-Take Availability extends the capabilities of Microsoft Cluster Service (MSCS) to create a stretch cluster. While MSCS and clustering in general provide a high level of application availability, MSCS clusters maintain only a single copy of the data and only provide failover within a single site. Built on top of MSCS, the GeoCluster feature offers added data protection, failover and disaster recovery. GeoCluster guarantees continual access to data and applications across sites and eliminates the single point of failure for improved MSCP protection.

GeoCluster benefits:

• Improved Cluster Data Protection: Reduces exposure to data loss and eliminates the single point of failure of shared disk storage with byte-level replication ensuring maximum application performance and minimum bandwidth requirements
• Enhanced Cluster Disaster Recovery: Ensures that business-critical data and applications can be recovered quickly through real-time, offsite data protection and failover.
• High Availability: Eliminates or greatly reduces downtime with automatic failover technologies.
• Greater Flexibility: Supports clusters using existing servers and storage because only replicated drive letters and capacity need to match between cluster nodes.
• Affordable and Easy-to-Use: GeoCluster provides the best possible protection at the lowest cost and is easy to use with MSCS clusters.

 Double‐Take Geo‐Cluster and Cluster Recoverability 

Most clusters require the use of shared storage. What about DR ? Double-Take comes to the challenge by allowing replication of clustered shared disk to either another cluster or a standalone  server! Failover and failback works much the same as server to server.

Instead of building a traditional cluster using shared storage that represents a single point of failure, why not create a cluster in a box, or a nothing shared cluster using Geo-Cluster. Geo-Cluster presents  itself a disk resource in a Microsoft Cluster configuration, but the disk resource in not shared, it is  replicated! Ultimate availability!
