Abstract
Aspects of the present disclosure relate to data deduplication (dedup) techniques for storage arrays. In embodiments, a sequence of input/output (IO) operations in an IO stream received from one or more host devices by a storage array are identified. Additionally, a determination is made as to whether previously received IO operations match the identified IO based on an IO rolling offsets empirical distribution model. Further, one or more data deduplication (dedup) techniques are performed on the matching IO sequence based on a comparison of a source compression technique and a target compression technique related to the identified IO sequence.
