Patent ID: 7636311

Claim:
A communication band ensuring method for a complex information platform apparatus including a plurality of processing modules, a switch for communication switching between processing modules, an adapter for connecting the processing modules with the switch, and a management module for managing these so that one or more processing units include one or more of the processing modules as constituent elements, the method comprising: a preparation step of previously maintaining an apparatus template management table in the management module, wherein the apparatus template management table contains an ensured band for an intra-apparatus communication as a specification item correspondingly to each apparatus type for the processing unit and prescribes a plurality of levels of setting specifications provided with different ensured band values for the intra-apparatus communication; a system configuration setting step of setting a combination of processing modules as constituent elements of a processing unit to be configured correspondingly to an apparatus number of the processing unit, setting an apparatus type of the processing unit, and selecting a setting specification for the processing unit from a plurality of levels of setting specifications for the apparatus type prescribed in the apparatus template management table; a setting verification step of calculating a total value of ensured bands for a communication corresponding to an adapter for each processing module from a settled apparatus configuration and a selected setting specification and comparing the total value with a communication capacity for the adapter to verify applicability of the selected setting specification; and a repetition step of, when a setting specification selected by the setting verification step is inappropriate, selecting another setting specification from the plurality of levels of setting specifications, reexecuting the setting verification step, and finally finding a setting specification in which a total value of ensured bands for a communication corresponding to an adapter for each processing module is smaller than or equal to a communication capacity of the adapter.
