What is Resource for a Cluster?

Any physical or logical component that can provide a service to a network client and that can be taken offline and brought online by Microsoft Cluster Server (MSCS) or Windows Clustering. Resources are physical or logical entities that are managed by a node of a cluster.

MSCS supports a number of types of resources, which you can manage using the Cluster Administrator program. These resource types include the following:

  • Dynamic Host Configuration Protocol (DHCP) servers
  • Distributed Transaction Coordinator
  • File shares
  • Generic applications such as database programs
  • Generic services such as Microsoft Windows NT services
  • Internet Information Services (IIS) virtual server for World Wide Web (WWW) and File Transfer Protocol (FTP)
  • IP addresses
  • Microsoft Message Queue (MSMQ) Server
  • Network names
  • Physical disks
  • Print spoolers
  • Time services

Related MSCS terminology with regard to resources includes the following:

  • Resource Group:
    An association of dependent or related resources running on one node of a cluster. Dependent resources require other resources in order to operate. All resources in a group move together between nodes during failover or failback operations.

     

  • Resource Monitor:
    A software component of MSCS that facilitates communication between the Cluster service and application resources.

MSCS resources always exist in one of the following states:
