Cluster Storage

Applies To: Windows Server 2008 R2

In a failover cluster, the storage must function correctly so that each node can read and write cluster configuration information or data. Only one server at a time should be able to access a given disk (volume) in the cluster storage. Configuration or hardware problems that prevent access to the storage can disrupt the function of the cluster.

Name Description

Cluster Shared Volumes

The Cluster Shared Volumes feature allows a given volume to be accessed by all nodes of a failover cluster. Each node can open and manage files on the volume. Therefore, multiple clustered virtual machines can use volumes on the same LUN (disk) while still being able to fail over (or move from node to node) independently of one another.

Cluster Storage Functionality

In a failover cluster, most clustered services or applications use at least one disk, also called a disk resource, that you assign when you configure the clustered service or application. Clients can use the clustered service or application only when the disk is functioning correctly.
