摘要： When a write-back request for writing back new data in a cache memory to disk devices forming a redundant configuration of RAID is generated, a write-back processing unit, reserves a parity buffer area in the cache memory, generates new parity, and then, writes the new data and the new parity to the corresponding disk devices. When an error in which the consistency of RAID is broken occurs in a plurality of the disk devices upon write performed by the write-back processing unit, a recovery processing unit reserves, in the cache memory, a cache stripe area storing data of the entire stripe including the new data which is to be written back, and causes the cache control unit to manage it.
摘要翻译：当产生写入高速缓冲存储器中的新数据到形成RAID冗余配置的磁盘设备的写回请求时，回写处理单元在高速缓冲存储器中保留奇偶校验缓冲区，产生新的奇偶校验，将新数据和新奇偶校验写入相应的磁盘设备。当由写回处理单元进行的写入时，在多个磁盘装置中发生RAID的一致性的错误时，恢复处理单元在高速缓冲存储器中保存存储整个数据的高速缓存条带区域包括要写回的新数据，并使高速缓存控制单元进行管理。

摘要： A method and apparatus for enhancing performance of parity check in computer readable media is provided. For example, in a RAID (N+1) configuration, a virtual data strip is added for a calculation of parity. Data of the virtual data strip is set so that a predetermined portion of a data area in the virtual data strip has a predetermined value. Consequently, performance of parity check performed in a data processing system having a RAID configuration can be enhanced.
摘要翻译：提供了一种用于增强计算机可读介质中的奇偶校验性能的方法和装置。例如，在RAID（N + 1）配置中，添加虚拟数据条以计算奇偶校验。虚拟数据条的数据被设置为使得虚拟数据条中的数据区的预定部分具有预定值。因此，可以提高在具有RAID配置的数据处理系统中执行的奇偶校验的性能。
