ABSTRACT:
A storage system in which a set of a data block and a redundancy block is stored has a plurality of control sections which respectively control a plurality of storages, a host connection unit which selects the control section controlling one of the storage in which a write data block which is a write-object block is to be stored, and a transfer unit which transfers the write data block to the control section. Each of the plurality of control sections includes a data block write section which writes the write data block transferred by a transfer unit to the storage in which the write data block is to be stored, a redundancy block update request section which requests the control section controlling the storage in which a redundancy block is to be stored to update the redundancy block, and a redundancy block update section which updates the redundancy block stored in the storage controlled by the control section when another of the control sections makes a request for updating the redundancy block.
