Abstract

　複数のディスク装置を備えたストレージシステム１に備えられ、複数のディスク装置へのデータの記憶を制御するストレージ制御装置３において、符号化部３２が、複数のディスク装置に格納すべきデータを、消失訂正符号により符号化し、符号化データを得る。記憶／読出部３３が、パーソナルコンピュータ５からの指示にしたがって、符号化データの複数のディスク装置への格納及び符号化データの複数のディスク装置からの取り出しを行う。送出部が、記憶／読出部３３において複数のディスク装置から取り出した符号化データを、ストレージシステム１Ａとネットワーク１０を介して接続されたストレージシステム１Ｂ宛に送出する。
