Managing Volumes

A Storage Center volume is a logical unit of storage that servers can access over a network. You can allocate more logical space to a

volume than is physically available on the Storage Center.

Attributes That Determine Volume Behavior

When a volume is created, attributes are associated with the volume to control its behavior.

Attribute Description

Storage Type Specifies the disk folder, tier redundancy, and data page size of the storage used by the volume.

Storage Profile Controls the RAID type, storage tiers, and data progression behavior for pages used by the volume.

Snapshot Profile Describes when to take periodic snapshots (also known as point-in-time copies) for one or more volumes

and the time at which snapshots are deleted (expired).

QoS Profile Specifies a profile to apply to volumes, to potentially limit I/Os that the volumes can perform, and also

defines their relative priority during times of congestion.
