Abstract:
1. A blade server apparatus comprising: a plurality of server modules; a backplane configured to mount the plurality of server modules; and an SMP coupling device having wiring lines for SMP coupling between the plurality of server modules, wherein each of the server modules has two processors controlled by firmware and a module manager configured to manage its own server module; the module manager has an ID determiner configured to inform each processor of a processor ID; each processor has a processing unit and an SMP virtual connecting unit configured to instruct one or more wiring lines of the SMP coupling device through which a packet received from the processing unit is to be transmitted; an ID converter configured to convert the processor ID for the SMP virtual connecting unit is provided in the firmware, wherein the ID determiner of the module manager is configured to: receive a number of processors of an SMP arrangement from an SMP coupling type identification signal circuit within the SMP coupling device, receive a slot number of each server module from a slot number identification signal circuit within the backplane, and determine a processor ID of each processor; and wherein the ID converter is configured to: in such a case that the number of processors is eight, convert the processor ID determined by the ID determiner to a processor ID for the SMP virtual connecting unit according to an ID conversion table and notify the SMP virtual connecting unit; and in such a case that the number of processors is two or four, notify the SMP virtual connecting unit of the processor ID having been determined by the ID determiner without conversion.
