Abstract
A direct-attached storage device software RAID system includes a chassis housing a software RAID subsystem coupled to physical storage devices, controller devices, and a hypervisor subsystem housed in the chassis. The software RAID subsystem uses the physical storage devices to provide a logical storage device to the hypervisor subsystem. The software RAID subsystem also presents a first controller device to the hypervisor subsystem as a primary controller device that is connected to the logical storage device. When the software RAID subsystem receives a command from the hypervisor subsystem directed to the primary controller device and identifying a logical storage subsystem in the logical storage device, it transmits the command to each of a subset of the physical storage devices that provide the logical storage subsystem in the logical storage device via a respective one of the controller devices that couples the software RAID subsystem to that physical storage device.
