PROBLEM TO BE SOLVED: To efficiently migrate data, while continuing operation of a system.SOLUTION: A storage control apparatus includes a rearrangement control section and a migration control section. The rearrangement control section controls first sub data to be rearranged from other storages to a first storage, on the basis of information on an arrangement where the first sub data formed by dividing first data is stored in a distributed manner in the first storage and one or more storages other than the fist storage. The migration control section controls the first data stored in the first storage to be migrated from the first storage to the second storage, after migrating a control section for input-output controlling the first data, from the first storage to the second storage.SELECTED DRAWING: Figure 7 |
