Abstract

　信頼性を向上させる。 　データ書き込み命令を受け取ると、診断情報付加手段（１ｂ）が、タイムスタンプを含む診断情報をデータに付加する。書き込み手段（１ｃ）は、データと、診断情報とを第１のストレージ装置に書き込み、データと同一の内容の冗長データと、診断情報とを第２のストレージ装置に書き込む。データ読み出し命令が取得されると、データチェック手段（１ｄ）は、第１のストレージ装置からデータと診断情報とを読み出し、データが正常か否かをチェックする。正常であれば、さらに、タイムスタンプ照合手段（１ｅ）によって、第２のストレージ装置のタイムスタンプが読み出され、第１のストレージ装置のタイムスタンプと照合される。一致していれば、読み出し手段（１ｆ）によって、第１のストレージ装置から読み出したデータが要求元へ送信される。
