摘要：提供了一种方法、系统和程序，用于管理布置在数据组织类型诸如RAID阵列中的多个盘存储单元上的条带中所存储的用户数据和奇偶数据的更新。在一个实施例中，将可能含有不一致的用户数据和奇偶数据的条带记录存储在盘存储单元中。另一方面，在将条带记录写入盘存储单元之前，用于多个写过程的条带条目被允许累积。另一方面，条带记录可被写入不同的盘存储单元，并使用生成号来标识条带的最近记录。

摘要： In a digital storage disk array system in which parity blocks are created and stored in order to be able to recover lost data blocks in the event of failure of a disk, high-activity parity groups are created for data blocks having high write activity and low-activity parity groups are created for data blocks not having high write activity. High-activity parity blocks formed from the high-activity data blocks are then stored in a buffer memory of a controller rather than on the disks in order to reduce the number of disk accesses during updating.

摘要： A storage subsystem receives writes from a computer via a standard storage subsystem interface. The storage subsystem reduces a number of the writes. A single drive of the storage subsystem has primary and redundant storage devices with storage device interfaces. A disk controller of the single drive implements a data redundancy scheme by storing data associated with the reduced number of writes in the primary storage devices and by storing computed redundancy information in the redundant storage devices. The disk controller is operable without a loss of data in the presence of at least a single failure of any of the storage devices. Optionally the storage devices are flash memory devices. Optionally the disk controller is operable without a loss of data in the presence of at least two failures of any of the storage devices when a number of the redundant storage devices is at least two.

摘要： Provided are a method, system, and program for managing updates of user data and parity data stored in stripes across a plurality of disk storage units arranged in a data organization type such as a RAID array. In one embodiment, a record of stripes potentially containing inconsistent user and parity data is stored on a disk storage unit. In another aspect, before writing a record of stripes to a disk storage unit, stripe entries for a plurality of write processes is permitted to accumulate. In another aspect, a record of stripes may be written to different disk storage units and a generation number is used to identify the latest record of stripes.
