摘要： A plurality of arrays of storage devices, each providing dual storage device redundancy, is provided. The plurality of arrays of storage devices includes a plurality of mirrored sets of primary storage devices, each including an even number of at least two or more primary storage devices. Each of the mirrored sets of primary storage devices stores a first and a second copy of data. The plurality of arrays of storage devices also includes a secondary storage device, which is a single physical storage device that stores a third copy of the data stored on each of the plurality of mirrored sets of primary storage devices. The secondary storage device has at least the capacity to store the data stored on the plurality of mirrored sets of primary storage devices. Dual storage device redundancy preserves data if data cannot be read from one or two physical storage devices in any array.

摘要翻译：提供了多个存储设备阵列，每个存储设备提供双重存储设备冗余。多个存储设备阵列包括多个主要存储设备的镜像组，每个主存储设备包括偶数个至少两个或更多个主存储设备。每个主存储设备的镜像集存储数据的第一和第二副本。多个存储设备阵列还包括辅助存储设备，其是存储存储在多个镜像的主存储设备组中的每一个上的数据的第三副本的单个物理存储设备。辅助存储设备至少具有存储存储在多个主要存储设备的多个镜像集合上的数据的能力。如果无法从任何阵列中的一个或两个物理存储设备读取数据，双存储设备冗余将保留数据。

摘要： The present invention provides for the expansion of a virtual storage device. Expansion of the virtual storage device includes adding one or more additional storage device units to an existing virtual storage device. Blocks or strips included in an added storage device unit are assigned addresses, to allow the added storage capacity to be accessed immediately. In order to reestablish a pattern of data storage addresses from the original storage device units of the pre-expanded virtual storage device across all of the storage device units of the post-expanded virtual storage device, temporary storage is provided. In particular, as a strip of data is relocated to its proper post-expand location, the data occupying that location is placed in a temporary storage buffer. Data in the temporary storage buffer is then written to the proper post-expand location for that data, with displaced data being written to a second temporary storage buffer.
