Patent ID: 8606984

Claim:
A computer system comprising: a compute element comprising a north chip that stores a translation of a first hierarchical bus number to a first physical bus number and a first bridge identifier of a first bridge, receives a request comprising an identifier of a destination, determines that the identifier comprises the first hierarchical bus number, replaces the identifier of the destination in the request with the first physical bus number and the first bridge identifier, and sends the request to the first bridge identified by the first bridge identifier; an input/output element comprising a south chip, wherein the input/output element is connected to the compute element via a connection mesh fabric, wherein the south chip comprises the first bridge and a first bus; and a first service processor comprising a first inventory controller, wherein the first service processor is connected to the south chip via a communications link, wherein the first inventory controller reads the first bridge identifier of the first bridge from the south chip and in response assigns the first physical bus number to the first bus and sends the first physical bus number to the south chip.
