Patent ID: 7761639

Claim:
A slot interface access device in a networked computer system of a plurality of networked computer systems comprising: a slot management module; a slot control module; and a physical slot to management slot contrast table, wherein the slot management module, the slot control module, and the physical slot to management slot contrast table are provided between an input and output control module and a slot interface architecturally lower than the input and output control module, the input and output control module being a layer below an application layer of the slot interface access device, the input and output control module accesses the slot interface using virtual slot identification information, the slot management module converts the virtual slot identification information into physical slot identification information while referring to the physical slot to management slot contrast table, and accesses the slot control module corresponding to the physical slot identification information, thereby realizing a physical access of the input and output control module to the slot interface, and the slot interface access device is executed in the networked computer system of the plurality of networked computer systems with a higher CPU capability than other computer systems of the plurality of networked computer systems each including the slot interface.
