Management of multiple capacity types in storage systems

摘要

A management of capacity types with different consumption policies for an object in a computing storage system is performed by updating a reference type bitmap in a segment-fragment table containing segments that reference fragments upon the creation of a segment for an object. A reference is created in an object-segment reference table, between the object and the segment, in compliance with a consumption policy upon the creation of one of the segments for the object. The reference types that reference the segment are removed upon deletion of the segment.

1. A method for management of capacity types with different consumption policies for an object in a computing storage system using a processor device, comprising:
updating a reference type bitmap in a segment-fragment reference table, containing a plurality of segments that reference fragments, upon the creation of one of the plurality of segments for an object; creating a reference in an object-segment reference table, between the object and the one of the plurality of segments, in compliance with one of the different consumption policies upon the creation of the one of the plurality of segments for the object; and removing the plurality of reference types that reference the one of the plurality of segments upon deletion of one of the plurality of segments.
