Abstract:
A method and system is disclosed for storage optimization of thin provisioning. Non-zero data units within data portions are re-allocated to specifically designated one or more areas in the physical storage space and the physical address of the non-zero data unit within the designated area is associated with the logical address of the non-zero data unit. In case the data portion is allocated to the physical storage, the physical storage space initially allocated to the data portion is returned to the pool of available physical storage space, thereby freeing the storage space for storing other data.
