PROBLEM TO BE SOLVED: To shorten copy time of a boot image in a plurality of boot image distribution servers and shorten acquisition time of the boot image on a start server.SOLUTION: M distribution servers 31a to 31m separately store m pieces of parts P1 to Pm obtained by dividing a boot image into m pieces, for example, so that the same part (e.g. P1) is not duplicated. A start server (e.g. 35a) comprises a distribution request unit for performing a distribution request of the parts P1 to Pm to the m distribution servers 31a to 31m, a reception unit for receiving the m pieces of parts P1 to Pm from the m distribution servers 31a to 31m in response to the distribution request, a storage unit for storing the parts P1 to Pm received in the reception unit, and an NW boot control unit for configuring the boot image from the m pieces of parts stored in the storage unit and starts a self-start server 35a by the boot image. |
