ABSTRACT:
An apparatus is equipped with a source oriented data move technique. In one embodiment, the apparatus is a computer system and the source oriented data moving technique is incorporated in a disk block relocation engine that relocates disk blocks in accordance with the specifications of a disk block relocation vector. In one embodiment, the disk block relocation vector is destination oriented, and the disk block relocation engine is complemented with an transformation function for annotating the destination oriented disk block relocation vector with data source information. The disk block relocation engine then identifies chains of serial disk block moves among the specified disk block moves, and performs the chains of serial disk block moves, keying off the annotated data source information.
