Planning for SFW cluster disk groups and volumes

A dynamic cluster disk group is a collection of one or more disks that behave as a single storage repository and which can potentially be accessed by different computers. Within each disk group, you can have dynamic volumes with different layouts.


You create a cluster disk group and volumes on only one node of a cluster. The volumes can be accessed by other nodes in a high-availability cluster by first deporting the cluster disk group from the current node and then importing it on the desired node. In a campus cluster, the volumes are mirrored across the storage arrays.

Before creating a disk group, consider the following:

The following topics provide additional guidelines for specific configurations:
