Abstract: A system and method for application aware de-duplication of data blocks in a virtualized storage array is disclosed. In one embodiment, in a method of de-duplication of data, a master list of metadata is created based on a number of occurrences of data blocks within a storage array. A first sublist of metadata is created from the master list of metadata. The first sublist of metadata is provided to a first component of a networked storage system. It is determined whether the data block being written has a corresponding entry in the master list of metadata based on a determination that a data block being written does not have any corresponding entry in the first sublist of metadata. The data block being written is replaced with a pointer based on a determination that the data block being written has a corresponding entry in the master list of metadata.
