and provides better utilization over those assets. Here the virtualization mechanism behind
thin provisioning is storage pool. The capacity of the storage pool is shared by all volumes.
When write requests come in, the space will be drawn dynamically from this storage pool to
meet the needs.

Thick Provisioning vs. Thin Provisioning
The efficiency of thin or thick provisioning is a function of the use case, not of the
technology. Thick provisioning is typically more efficient when the amount of resource used
very closely approximates to the amount of resource allocated. Thin provisioning offers
more efficiency where the amount of resource used is much smaller than allocated, so that
the benefit of providing only the resource needed exceeds the cost of the virtualization
technology used.
