Abstract:
A computer-implemented method for a high speed peripheral component interconnect input/output virtualization configuration creates a set of virtual function path authorization tables, receives a request including a virtual function, from a requester, to provide requested data, and identifies a source address in the source system and a target address in each target system of the target set of systems. A virtual function work queue entry for the source system is created containing the source and the target address and responsive to determining the virtual function is authorized, write the requested data from the source address of the source system through a firewall of an intermediate device into the target address of each target system, wherein the intermediate device is one of a multi-root peripheral component interconnect device and a single root peripheral component interconnect device, and issuing a notice of completion to the requester.
