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。

摘要： In the present invention, for each set of blocks [#(0) to #(N-1)] storing update data, a history block [#(N)] storing an update state value, for example, a generation, time or check code, showing an update state is provided, constituting a set of management data as a check object. When writing update data on a disk, a new update state value is calculated for the same set of management data and stored in memory as update state confirmation value. The new update state value is also set as write data in the history block in the same set of management data, and the entire of the set of management data including update data and update state value are written onto a disk. The history block is read and disk write omissions are detected by comparing the update state value and the update state confirmation value stored in memory.
摘要翻译：在本发明中，对于存储更新数据的每个块[＃（0）〜＃（N-1）]组，存储更新状态值的历史块[＃（N）]，例如生成，时间或检查代码，显示提供更新状态，构成作为检查对象的一组管理数据。在磁盘上写入更新数据时，为同一组管理数据计算新的更新状态值，并将其作为更新状态确认值存储在内存中。新的更新状态值也被设置为同一组管理数据中的历史块中的写入数据，并且包括更新数据和更新状态值的整个管理数据集合被写入盘中。读取历史块，并通过比较存储在存储器中的更新状态值和更新状态确认值来检测磁盘写入缺失。

摘要： Storage destination controller devices wherein N number of data strips and M number of parity strips comprised in each stripe are determined so that the parity strips are not continuously stored to the same memory device between two consecutive stripes when a plurality of stripes, each comprising the N number of data strips and the M number of parity strips of different types, are distributed and stored to the N+M number of memory devices.

摘要： In case an error statistics of one of the disk drives exceeds a predetermined threshold, the disk is determined as a suspect disk drive. A recovery mode is set successively. During the time when a setting of the recovery mode is in progress and no access is made from a host 16 in this time, the address range of the suspect disk drive is specified. At the same time, a processing is started in that the data of the suspect disk is copied to a spare disk 34 sequentially to recover the data. The data of the suspect disk drive is copied to the spare disk drive 34 to recover the data when the address range of the suspect disk drive does not correspond to the write failure address range of a management table 48. The data of a normal disk drive is copied to the spare disk drive 34 to recover the data when the address range of the suspect disk drive corresponds to the write failure address range of the management table 48. Upon the completion of the recovery of the data, the suspect disk drive 32 is separated and replaced with the spare disk drive 34.
摘要翻译：如果其中一个磁盘驱动器的错误统计信息超过预定阈值，则将磁盘确定为可疑磁盘驱动器。恢复模式依次设置。在恢复模式的设置正在进行的时间内，在此时不从主机16进行访问，指定了可疑磁盘驱动器的地址范围。同时，开始处理，其中可疑盘的数据被顺序复制到备用盘34以恢复数据。当可疑磁盘驱动器的地址范围不对应于管理表48的写入失败地址范围时，可疑磁盘驱动器的数据被复制到备用磁盘驱动器34以恢复数据。当可疑磁盘驱动器的地址范围对应于管理表48的写入失败地址范围时，普通磁盘驱动器的数据被复制到备用磁盘驱动器34以恢复数据。在完成数据恢复之后，可疑磁盘驱动器32被分离并被备用磁盘驱动器34代替。

摘要： An input/output scheduling unit forms input/output groups obtained by grouping inputs/outputs to/from a disk apparatus. The input/output scheduling unit defines a ratio of the time during which each input/output group uses the disk apparatus and defines quanta &tgr;1 to &tgr;3 during which each input/output group can continuously use the disk apparatus on the basis of the defined time ratios. When input/output requests are received from a plurality of input/output groups to the disk apparatus, the input/output scheduling unit performs the time-sharing for sequentially switching the allocating times &tgr;1 to &tgr;3 between the input/output groups which competed and using the disk apparatus. Further, an allocating time of the remaining quanta is distributed to the quanta on the shortage side by an allocating time control unit in accordance with a degree of jam of each input/output group.
摘要翻译：输入/输出调度单元形成通过将来自盘装置的输入/输出分组获得的输入/输出组。输入/输出调度单元定义每个输入/输出组使用盘装置的时间的比率，并且定义量子tau1至tau3，在此期间，每个输入/输出组可以基于所定义的时间比率连续地使用盘装置。当从多个输入/输出组向盘装置接收到输入/输出请求时，输入/输出调度单元执行用于顺序切换竞争和使用的输入/输出组之间的分配时间tau1至tau3的分时盘装置。此外，通过分配时间控制单元根据每个输入/输出组的卡纸程度将剩余量子的分配时间分配给短缺侧的量子。
