In one embodiment of the present invention, a computer system includes an application program, a plurality of storage devices, at least one storage driver that provides an interface between the application program and the plurality of storage devices, and a mirror driver that receives an I/O request from the application program requesting access to one of the plurality of storage devices, duplicates the I/O request to create a plurality of I/O requests, and sends the plurality of I/O requests to the storage driver so that each of the plurality of storage devices receives and processes one I/O request. In embodiments of the present invention, the computer system further includes a mirror application that communicates with the mirror driver to establish mirror sets of the plurality of storage devices.
