Clustered Services and Applications

  • Artículo

Applies To: Windows Server 2008

A service or application configured within a failover cluster consists of multiple clustered resources, and uses configuration information that tells the cluster the order in which to start or stop the resources. The successful function of the clustered service or application depends on whether necessary clustered resources can come online.

Managed Entities

The following is a list of the managed entities that are included in this managed entity:

Name Description

Clustered File Server Instance

A clustered file server instance is a configuration through which you can share folders and files that reside on one or more disks in the cluster storage. To clients, the name of the server through which the folders and files are shared always appears the same. However, within the cluster, any node can own the file server instance at a given time.

Clustered WINS or DHCP Instance

A clustered WINS server instance or DHCP server instance can be hosted by any node in the cluster at a given time, which can increase the availability of WINS or DHCP.

Clustered DFS Namespace Instance

A clustered DFS namespace instance can be hosted by any node in the cluster at a given time, which can increase the availability of the DFS namespace.

Clustered Generic Script Instance

A Generic Script Instance uses a script that monitors and controls a server application. The correct functioning of the script is very important in determining whether the combination of Cluster service, script, and application will work together to increase availability.

Clustered Generic Service Instance

A clustered Generic Service instance can increase the availability of a service that is not "cluster-aware" (not originally designed to run in a cluster).

Clustered Generic Application Instance

A clustered Generic Application instance can increase the availability of an application that is not "cluster-aware" (not originally designed to run in a cluster).

Aspects

The following is a list of all aspects that are part of this managed entity:

Name Description

Clustered Service or Application Availability

In a failover cluster, a clustered service or application can come online (and be available for clients to use) only when the necessary clustered resources within it can come online.
