An ILM device manages data arrangement in multiple storage areas to each of which a service level (called SLA), which guarantees a service level to data, is assigned, checks whether the SLA of a storage area satisfies a required service level object (SLO) of data to which the SLO is assigned, and determines the data arrangement so that the data is stored in a storage area whose SLA satisfies the SLO. A data migration execution unit migrates the data in storage based on the data arrangement determined by the ILM device. |
