Abstract:
1. A method for removing duplicate provisions within a data storage system, the method comprising: providing a plurality of storage territories, each of the storage territories being subdivided into one or more provisions within a physical storage of the data storage system; providing a de-duplication territory; identifying a plurality of duplicate provisions among the one or more provisions within the physical storage of the data storage system; allocating a new provision within the de-duplication territory for each of the plurality of duplicate provisions for consolidating the plurality of duplicate provisions; remapping each of the plurality of duplicate provisions to one of the newly allocated provisions within the de-duplication territory; and consolidating the newly allocated provisions associated with each of the plurality of duplicate provisions within the de-duplication territory to point to a single physical storage provision within the physical storage, wherein the plurality of duplicate provisions are indirectly mapped to the single physical storage provision within the physical storage through the de-duplication territory.
