PROBLEM TO BE SOLVED: To provide a computer-implemented method for creating a redundant system configuration, a data processing system, and a computer program. SOLUTION: The computer-implemented method creates a set of virtual function path authorization tables, and receives a request from a requester to provide requested data from a virtual function wherein the virtual function is performed by a single root or a multi-root peripheral component interconnect device. Further a receive buffer is created in a selected address range in a set of address ranges as well as a virtual function work queue entry for the virtual function containing an address of the receive buffer in the selected address range. Responsive to a determination that the virtual function is authorized, the requested data are written into the receive buffer of the selected address range in the one or more systems, and responsive to writing the requested data, a notice of completion is issued to the requester.
