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 Species the disk folder, tier redundancy, and data page size of the

storage used by the volume.

Storage Prole Controls the RAID type, storage tiers, and data progression behavior

for pages used by the volume.

Snapshot Prole 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 Prole Species a prole to apply to volumes, to potentially limit I/Os that

the volumes can perform, and also denes their relative priority

during times of congestion.
