PROBLEM TO BE SOLVED: To provide an apparatus, a system and a method that include a plurality of object-based storage devices (OSDs) used for constructing a RAID (Redundant Array of Independent Disks) type system. SOLUTION: The apparatus and the method for a storage system for storing data on an object basis, where the object has attribute information and data. The storage system has a plurality of (N) data storage devices and at least one redundant data storage device. When the storage system receives a write request with an object, the object is divided into N sub-objects which each have the same size. Thereafter, the N sub-objects are written to the data storage devices respectively. Further, the parity is calculated from each of the sub-objects. In one embodiment the parity is stored in a redundant data storage device. COPYRIGHT: (C)2006,JPO&NCIPI
