Data storage method and data storage for averaging workload in a redundant storage configuration
Duplicate data are stored in separate storage units SU(0) 16 and SU(1) 26, respectively. The storage area in each of SU(0) 16 and SU(1) 26 is divided into master storage regions and sub storage regions each of which is allocated alternately to the storage units in increments of fixed addresses. The store request is issued to both of the storage units allocated the master storage region and the sub storage region, and the fetch request is issued to one of the storage units allocated the master storage region from the RSC(0) 34 and RSC(1) 44.
