Abstract
Techniques are disclosed for determining ownership of a data segment. The techniques include providing a data segment in a data storage appliance that facilitates multiple references of the data segment by one or more storage entities. The techniques also include maintaining a plurality of counts in connection with the data segment, the plurality of counts comprising (i) a first count representing a sum of first values that identify the respective storage entities associated with each reference of the data segment, (ii) a second count representing a sum of second values that derive from key values of the respective storage entities associated with each reference of the data segment, and (iii) a third count representing a number of references of the data segment by the respective storage entities. The techniques also include determining whether the said storage entity exclusively owns the data segment based on the plurality of counts and a key value of one of the respective storage entities.
