<p>To provide a disk array control apparatus which enables security of data from a host controller along with prevention of the degradation of process performance during rebuild processing. The disk array control apparatus includes a host interface unit which receives write data from a host controller; a rebuild control unit which controls rebuild processing for creating recovery data writes the created recovery data into a disk medium; and a disk control unit which writes the write data which is received from the host interface unit into the disk medium and writes at least a part of the recovery data which is created based on the control of said rebuild control unit into a write cache.</p> |
