What is Thin Provisioning?

Thin provisioning is a method of dynamically allocating storage capacity on demand across multiple applications in a flexible and efficient manner, thus reducing storage utilization rates.

Thin provisioning provides a new approach to storage provisioning, one that can eliminate waste by reserving capacity dynamically to keep slightly ahead of the written data. In doing so, thin provisioning gets rid of the upfront capacity reservation, thereby unlocking and freeing the capacity that would otherwise be reserved upfront and trapped within thick provisioned volumes. In aggregate, this leads to significant efficiency gains compared to typical thick provisioned storage deployments.
