STORAGE DEVICE SHARING SYSTEM, MANAGEMENT DEVICE, PROCESSING DEVICE, STORAGE DEVICE SHARING METHOD, MANAGEMENT METHOD, ACCESS METHOD AND PROGRAM

摘要

Provided are a storage device sharing system, management device, processing device, storage device sharing method, management method, and access method capable of controlling access by each processing device to storage devices while preventing load from concentrating on a specific apparatus, and also wherein, even if a management device fails, each processing device can suitably access the storage devices. The storage device sharing system includes M (M is an integer greater than or equal to 2) processing devices sharing N (N is an integer greater than or equal to 2) storage devices, and a management device for controlling access to the storage devices by the processing devices; wherein the management device includes a store means for storing priority order information indicating a priority order of each storage device, and a management means for transmitting the priority order information to each processing device; and the processing devices include a communication means for receiving the priority order information, a storage means for storing the priority order information, and a control means for controlling access to the storage devices on the basis of the priority order information within the storage means.
