Defining NT Clusters
An NT Cluster is comprised of two identical Windows NT Server systems connected to a shared SCSI storage device. The cluster shared disk storage can be either disks on the same SCSI bus or disks connected through a smart SCSI controller. The Compaq NT Clusters’ documentation describes all the possible and supported configurations.
NT Clusters allow server application providers to create and configure their server applications to run seamlessly by providing failover. Failover is defined as the moving of resources from a primary node to a secondary node when the primary node either crashes or there is manual intervention to force resource reallocation from one node to another.
Within the scope of the NT Cluster, there are a few tools to manage the cluster. The primary tool is the Cluster Administrator from which the Failover Manager manages the cluster failover resources.
