ABSTRACT:
Disclosed is a system and method for transmitting computer data within a single computer system along more than one physical data path by providing a multiple-path driver that creates virtual (or non-physical) data paths without modifying the source code of the operating system. The system and method may be used with any computer hardware regardless of manufacturer. In one embodiment, a multiple-path driver may be used within a Linux operating system to create virtual data paths and transmit data between the upper-level drivers of the Linux system and at least one computer data storage device without modifying the Linux source code.
