Abstract
Systems and methods for efficient deduplication and/or provisioning of LUNs are disclosed. A first unique data block pool for a first LUN of a plurality of deduplicated LUNs is accessed, the first unique data block pool comprising a first plurality of unique data blocks for representing data stored on the first LUN. A second unique data block pool for a second LUN of the plurality of LUNs is accessed, the second unique data block pool comprising a second plurality of unique data blocks for representing data stored on the second LUN. It is determined a correspondence metric for the first unique data block pool and the second unique data block pool exceeds a pre-determined threshold. The first LUN and the second LUN are joined to form a first combined LUN. The first unique data block pool and the second unique data block pool are joined.
