Abstract: A personal digital assistant includes an input section for designating, when a user requests information based on positional information, whether user desires to acquire wide-area information or narrow-area information. If acquisition of narrow-area information is desired, a managing server removes noise by a noise removal processing section which makes a check to determine whether or not the wide-area information is noise. Hence, information desired by the user is preferentially displayed.

Abstract: A user operates an input device to set information necessary for reserving a volume and a port while looking at a screen for reservation management displayed on a display device Next, a storage management program retrieves reservable volumes and ports using a volume retrieval subprogram of a policy basis. At this point, when a policy concerning performance is inputted, the storage management program inquires of a performance analysis program of a storage performance management server whether the performance is satisfied. When the volume and the port are found, the storage management program stores reservation information in a reservation management DB using a reservation subprogram. When the volume and the port are not found, the storage management program judges whether an alternative volume for the reserved volume is present using a volume adjustment subprogram.
