Abstract
An aspect includes providing a metadata structure having a logical level that points to a virtual level and a physical level to which the virtual level points. The method also includes storing, at the virtual level, a reference counter for each of a plurality of virtual-level type storage address entries in the metadata structure, and providing a pointer in the metadata structure between each pair of a number of pairs of virtual level address entries in which corresponding pages share a set of common sectors. The reference counter tracks a number of instances in which a corresponding pointer points to a corresponding virtual level address entry. An aspect further includes storing a single instance of the common sectors at the physical level.
