Geocluster - Data Replication for Clustered environments...

Based on NSI Software's proven Double-Take replication technology, GeoCluster extends the capabilities of Microsoft Cluster Service (MSCS) to create a stretch cluster. While MSCS, and clustering in general, provides 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, GeoCluster offers added data protection, assuring continual access to data and applications across sites.

GeoCluster provides:

Multi-site disaster recovery protection

Real-time, continuous offsite data protection and failover to ensure that business-critical data and applications can be recovered quickly, despite complete failure at any single site

Improved data availability

With byte-level replication ensuring maximum application performance and minimum bandwidth requirements, GeoCluster reduces exposure to data loss and eliminates the single point of failure of shared disk storage

Reduced downtime

Application failover is fast and automatic, eliminating or greatly reducing any downtime

More flexibility

Only replicated drive letters and capacity need to match between cluster nodes making it possible to create clusters using existing servers and storage. GeoCluster supports active/active configurations where each node can be supporting production users but failover for the other node as required.

Lower cost option than building a traditional cluster

Since replication occurs over standard IP LAN or VLAN connections, dedicated links, channel extenders or storage routers are not required.

Microsoft Endorsed:

Endorsing GeoCluster, Michel Gambier, Group Product Manager of Enterprise Marketing for Microsoft Corporation, stated, "We are excited to see NSI Software taking advantage of the cluster service in Microsoft Windows 2000 to add advanced capabilities such as data replication. By combining the capabilities of Microsoft Cluster Service with the capabilities of NSI Software's GeoCluster, our customers can realize even higher levels of availability and protection for their business-critical applications and data."
