Abstract: front page image
(EN)It is possible to increase the response speed of a disc device in rebuild processing. A disc array control device judges whether a normal read-out request has been made during the rebuild processing. If a read-out request has been made during the rebuild processing, data read-out is performed while successively switching a plurality of disc devices in a predetermined block size unit smaller than a block size which is read out by each disc device.
(FR)Selon l'invention, il est possible d'augmenter la vitesse de réponse du dispositif à disques dans le processus de reconstitution. Le dispositif de commande de la matrice de disques juge si une demande de lecture normale a été effectuée pendant le processus de reconstitution. Si c'est le cas, la lecture de données est réalisée parallèlement à la commutation successive d'une pluralité de dispositifs à disques dans une unité de longueur de bloc prédéterminée, inférieure à la longueur de bloc qui est lue par chaque dispositif à disques.
(JA) 本発明の目的は、リビルド処理中のディスク装置の応答を速めることである。ディスクアレイ制御装置は、リビルド処理中に通常の読み出し要求かあったか否かを判定し、リビルド処理中に読み出し要求があった場合には、通常の読み出し時に各ディスク装置が読み出しを担当するブロックサイズより小さい所定のブロックサイズ単位で複数のディスク装置を順に切り換えてデータの読み出し行う。
