Abstract
A system, method, and computer program product are provided for implementing shared reference counters among a plurality of virtual storage devices. The method includes the steps of allocating a first portion of a real storage device to store data, wherein the first portion is divided into a plurality of blocks of memory and allocating a second portion of the real storage device to store a plurality of reference counters that correspond to the plurality of blocks of memory. The reference counters may be updated by two or more virtual storage devices hosted in one or more nodes to manage the allocation of the blocks of memory in the real storage device.
