ABSTRACT:
A system and method for reclaiming unused space from a thinly provisioned data container served by a storage system. A host-side agent detects blocks of the data container that may be freed and sends a novel Punch Hole command to the storage system associated with the data container. The storage system allocates the appropriate blocks in response to the Punch Hole command.
