Summary:It is provided a management server comprising a memory, a processor configured to access to the memory, and a network interface through which the management server holds communication to/from a storage apparatus and a file server. The storage apparatus includes a storage device, which is divided into pages each having a determined capacity to store data. The file server is configured to manage, on a file-by-file basis, data that is stored in the storage apparatus. The processor is configured to: obtain an I/O count per unit time of access to pages which stores data contained in the file; and compare a policy applied to the file and imbalance in I/O to a part of the data contained in the file, and output a changed policy in the case where it is found that the policy applied to the file needs to be changed as a result of the comparison.
