Deduplication (dedupe) is the process of reducing redundant copies of data that consume storage capacity. The redundant copies are replaced with pointers. The pointers provide the access for the subsequent requests of that shared data by multiple sources. In PowerMax systems, dedupe is accomplished through a series of functions and components including hardware acceleration, dedupe algorithm, hash table and dedupe management object (DMO).
