A direct-attached storage device software RAID control communication system includes a chassis housing a software RAID subsystem coupled to an operating system and a controller device. The software RAID subsystem provides a virtual adapter device and a virtual miniport driver for the operating system, provides a physical miniport driver for the controller device, and provides a helper driver between the virtual miniport driver and the physical miniport driver. The helper driver identifies, via the physical miniport driver, a communication entry point for the controller device and logical storage subsystem(s) provided by storage device(s) connected to the controller device, and identifies them to the virtual miniport driver. The virtual miniport driver then presents a logical storage device to the operating system that includes at least some of the logical storage subsystem(s), and uses the communication entry point to transmit communications between the operating system and the physical miniport driver.
