Title (EN) STORAGE DEVICE
(FR) DISPOSITIF DE STOCKAGE
(JA) ストレージ装置
Abstract:
(EN) A storage device comprising: a plurality of flash memory devices, each of which has a plurality of flash memory chips, each chip having a plurality of physical blocks, which are data erase units, and has a flash controller which provides a logical storage region associated with one or more physical blocks of the plurality of physical blocks; and a RAID controller which manages a plurality of virtual drives, each including part of the logical storage regions provided by the plurality of flash memory devices, and controls the plurality of virtual drives as RAID groups.
(FR) L'invention concerne un dispositif de stockage comprenant : une pluralité de dispositifs de mémoire flash, dont chacun comprend une pluralité de puces de mémoire flash, chaque puce ayant une pluralité de blocs physiques, qui sont des unités d'effacement de données, et a un dispositif de commande de mémoire flash qui fournit une région de stockage logique associée à un ou plusieurs blocs physiques de la pluralité de blocs physiques ; et un dispositif de commande RAID qui gère une pluralité d'entraînements virtuels, chacun comprenant une partie des régions de stockage logiques fournies par la pluralité de dispositifs de mémoire flash, et commande la pluralité d'entraînements virtuels comme groupes RAID.
(JA)  ストレージ装置は、複数のデータ消去単位である物理ブロックをそれぞれに有する複数のフラッシュメモリチップと、複数の物理ブロックの1つ以上に論理記憶領域を対応付けて論理記憶領域を提供するフラッシュコントローラと、をそれぞれに有する複数のフラッシュメモリデバイスと、それぞれが、複数のフラッシュメモリデバイスのそれぞれによって提供される論理記憶領域の一部を含む複数の仮想ドライブを管理し、複数の仮想ドライブをRAIDグループとして制御するRAIDコントローラと、を有する。
