ABSTRACT:
A storage unit comprises a plurality of storage modules, each of which is dynamically assigned to and used as each area in a main storage (MS) or an extended storage (ES). The storage unit or a system controller has address arrays for MS and for ES which store information indicating which of the storage modules comprised in the storage unit each area in the MS and the ES corresponds to. When the contents of the MS/ES address arrays are rewritten to change a storage module belonging to the ES to a storage module belonging to the MS, a page-in operation is realized without executing an actual data move operation. Similarly, a page-out operation is realized without executing an actual data move operation by changing a storage module belonging to the MS to a storage module belonging to the ES.
