Abstract:
A storage control apparatus of the present invention is able to duplicatively manage data in a cache memory even during maintenance work. When a memory package CMPK3 specified by a user is removed from the apparatus 1 (S2), a microprocessor 2 changes a pair that has been configured using CMPK2 and CMPK3 to a pair of CMPK2 and a free area of a CMPK1. As a result, received data (S5) is respectively written to multiple cache memories (S6, S7), and duplicatively managed.
