摘要

A method of retrieving data blocks in a storage area network, the method comprising selecting a first one of a plurality of paths to a storage device; retrieving a first number of sequential data blocks from the storage device along the first path; and selecting a second one of the plurality of paths for retrieving subsequent sequential data blocks from the storage device. One or both of the selected paths may be the path with the lowest average turnaround time of all of the available paths.
