Abstract

Module combination candidates which compose an information platform, to reduce human error when a platform is composed, and to permit automatic configuration changes. There is therefore provided a compound information platform comprising information platforms combining one or more universal processing modules and dedicated processing modules, wherein a management module has a means which computes processing module combination candidates when newly composing the information platform, computes the sum total value of the maximum guaranteed communication bandwidth of an IO protocol interface for each physical interconnection PL using an interface setting management information, adding an additional maximum guaranteed communication bandwidth due to a processing module combination candidate, and determining whether this is a possible module combination candidate by comparing the addition result with the maximum permitted communication bandwidth of each physical interconnection.
