Abstract
A method is provided for performance by an I/O Coordination module of a computing device operating as a data storage system in order to obtain and process physical extent mappings in the context of an XCOPY Lite or XCOPY type operation. The method involves breaking down the source region into physical source extents with reference to a container filesystem representing the logical volume of the source as a file. The I/O Coordination module is then able to separately process each of these physical source extents and also obtain its corresponding physical destination extents with reference to the container filesystem, which also represents the logical volume of the destination as a file. The I/O Coordination module is then able to cause integrated copy commands to be issued to an underlying physical storage driver. An apparatus, system, and computer program product for performing a similar method are also provided.
