Abstract: A management technique provides for management of power supply modules. In multiple computer equipment, in response to a load state, if an operation system issues a command that changes a processor state of a processor to a sleep state, a management module is notified through a management network MI that the processor state has changed. The management module holds a system information, and performs the steps of: updating system information because the processor state has changed; from this system information, calculating the power consumption required for the multiple computer equipment; determining the number of required AC-DC power supply modules to be operated; and changing the number of operating AC-DC power supply modules by use of a control interface PA.

Abstract: Provided is a technology for increasing reliability of communication carried out by OSes and application programs operating on logical partitions set on a computer. The computer has multiple logical partitions constructed therein by a control program, the physical interfaces are shared by virtual interfaces respectively set for the multiple logical partitions, and the memory module stores management information indicating correspondences between the physical interface and the virtual interface.

Abstract: An object of the present invention is to provide a management technique for managing power supply modules. In multiple computer equipment 100, in response to a load state, if an operation system 1101 issues a command that changes a processor state of a processor 1021 to a sleep state, a management module 107 is notified through a management network MI that the processor state has changed. The management module 107 holds a system information 108, and performs the steps of: updating system information 108 because the processor state has changed; from this system information 108, calculating the power consumption required for the multiple computer equipment 100; determining the number of required AC-DC power supply modules 1061, 1062, . . . to be operated; and changing the number of operating AC-DC power supply modules 1061, 1062, . . . by use of a control interface PA.

Abstract: A compound computer machine in which a plurality of modules are installed in one casing and in which trouble of management in combining modules to construct a computer machine is reduced. In the compound computer machine including a processor module; a component module which is combined with the processor module to construct a computer machine; and a management module which manages the processor module and the component module, the management module has module combination constraint information and priority information for constructing the computer machine, prepares installation information of the compound computer machine on receiving a request for constructing the computer machine, thereafter prepares module combination candidate information from the constraint information, and adds priority to the combination candidate information in a case where there exists the priority information to manage the constructions of the modules.
