ABSTRACT:
An apparatus and 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 each of which have the same size. Thereafter, each of the N sub-objects is written to the data storage devices. Further, the parity is calculated from each of the sub-objects. In one embodiment the parity is stored in a redundant data storage device.
