Abstract

　ストレージノードにかかる負荷を分散し、アクセス性能を向上させる。 　管理情報記憶手段（１ａ）には、仮想的な論理セグメントの識別情報と、論理セグメントに対応付けられた実データ記憶領域の物理セグメントの識別情報と、を関連付けた管理情報が記憶されている。データアクセス手段（１ｂ）経由でアクセス要求を取得すると、セグメント特定手段（１ｃ）は、アクセス対象範囲の論理セグメントと、対応する物理セグメントとを特定する。再配置手段（１ｄ）は、特定された論理セグメントと物理セグメントとを、サブ論理セグメントとサブ物理セグメントとに分割し、所定の規則に従って、サブ論理セグメントをサブ物理セグメントに再配置する。データアクセス手段（１ｂ）は、再配置によって対応付けられたサブ論理セグメントとサブ物理セグメントとの間で、アクセス制御を行う。
