Understanding MSCS

A server cluster is a group of two or more physically separate servers running MSCS and working collectively as a single system. The server cluster, in turn, provides high availability, scalability, and manageability for resources and applications. In other words, a group of servers is physically connected via communication hardware (network), shares storage (via SCSI or Fibre Channel connectors), and uses MSCS software to tie them all together into managed resources.

Server clusters can preserve client access to applications and resources during failures and planned outages. If one of the servers in a cluster is unavailable due to failure or maintenance, resources and applications move to another available cluster node.
