PROBLEM TO BE SOLVED: To efficiently perform tuning of a logical partition to be accessed randomly.SOLUTION: Based on contents of access from an information processing device 2, acquisition means 1a acquires information indicating a frequency of random access to a logical partition B1 and information indicating a size of data subjected to the random access and stores the acquired information in storage means 1b. Control means 1c refers to the storage means 1b and, when the frequency of random access becomes equal to or more than a threshold, determines sizes of storage regions B21, B22 to be allocated to the logical partition B2 on the basis of the information indicating the size of data subjected to the random access. The control means 1c creates a logical partition B2 using a plurality of storage devices. The control means 1c controls access from the information processing device 2 so as to access the logical partition B2 in place of accessing the logical partition B1. |
