Definitions Server Cluster Reliability"A server cluster is a group of independent servers running Cluster service and working collectively as a single system. Server clusters provide high-availability, scalability, and manageability for resources and applications by grouping multiple servers running Windows® 2000 Advanced Server or Windows 2000 Datacenter Server."The purpose of server clusters is to preserve client access to applications and resources during failures and planned outages. If one of the servers in the cluster is unavailable due to failure or maintenance, resources and applications move to another available cluster node." Server Cluster ScalabilityScalability.
