Thin Provisioning

Thin provisioning allocates physical capacity from a virtualized pool of storage to logical volumes on a just-in-time basis (also known as allocate on write), rather than preallocating large amounts of capacity in anticipation of an application’s needs. It eliminates instances of stranded capacity and improves storage utilization rates, often into the 75%-to-80% range.
