About Volumes

You manage the array's physical disks as a pool of storage space for creating volumes. Volumes are "containers" into which applications, databases, and file systems can put data. Volumes are created from the virtual disks, based on the characteristics of the storage pool associated with the virtual disks. Based on your specifications, the array automatically allocates storage a virtual disk that can satisfy your volume configuration requirements.

There are several different types of volumes:

You can create up to 256 volumes on each virtual disk. During or after standard volume creation, you can map a host or host group to the volume in order to give the host or host group read/write privileges to the volume. Each host, including any host that is a member of a host group, must be assigned one or more initiators before the host or host group can be mapped to the volume. To see the current volumes, go to the Volume Summary page, as described in Displaying Volume Information.

There are a number of other things you can do with volumes, depending on their type:
