Data misalignment detection and correction in a computer system utilizing a mass storage subsystem

摘要

An embodiment of a data misalignment correction method for a mass storage drive array subsystem coupled to a computer operating system having input/output data block requests is provided. The data misalignment correction method includes automatically determining an amount of misalignment between a requested data block and a current data block alignment configuration, using the amount of misalignment to determine a preferred data bock alignment and realigning data block requests on the mass storage device according to the preferred data block alignment.
