Symantec Cluster Server for Windows (VCS) provides application management, high availability, and disaster recovery for all major Windows based applications in a Microsoft Logical Disk Manager and NetApp SnapDrive and SnapMirror environment. VCS enables you to monitor systems and applications and restarts services on a different system when hardware or software fails.

A VCS cluster connects multiple independent systems to provide failover capability thus reducing application downtime. VCS supports local and global clusters. VCS provides transparent server, application and data failover.
