What is Microsoft Cluster Server (MSCS)?
MSCS is a built-in feature of Windows NT Server, Enterprise Edition. It is software that supports the connection of two servers into a “cluster” for higher availability and easier manageability of data and applications. MSCS can automatically detect and recover from server or application failures. It can be used to move server workload to balance utilization and to provide for planned maintenance without downtime. And, over time, MSCS will also become a platform for highly scalable, cluster-aware applications.
