Abstract
A virtual disk subsystem and method for providing a virtual local drive are disclosed. The virtual disk subsystem includes a channel bridge, such as an Advanced Technology Attachment (ATA) bridge, that receives disk commands from a disk controller, as well as a disk emulator in communication with the channel bridge and a network interface. The disk emulator includes control logic that receives disk commands from the disk controller via the channel bridge and, in response, retrieves data from a remote data storage device and forwards the data to the disk controller, such that the disk controller perceives the remote data storage device as a local device. In an exemplary embodiment, the virtual disk subsystem allows a standard operating system (OS) in a data processing system to function as if the data processing system included the emulated drive.
