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： A RAID system access a physical disk and perform Rebuild/Copy back processing according to a host I/O request, so as to implement high-speed Rebuild/Copy back processing without interfering with the processing of a normal I/O. When one disk device fails, out of a plurality of disk devices constituting a RAID configuration, the controller performs Rebuild/Copy back processing to reconstruct the RAID. In Rebuild/Copy back, the controller reads the data from one disk and writes the data to another disk, so the presence of a normal I/O is judged, and when a normal I/O is absent, read and write of these different disk drives are executed simultaneously. By this, the Rebuild/Copy back time can be decreased.
摘要翻译： RAID系统访问物理磁盘，并根据主机I / O请求执行重建/复制处理，以便在不干扰正常I / O的处理的情况下实现高速重建/复制回加工。当一个磁盘设备发生故障时，在构成RAID配置的多个磁盘设备中，控制器执行重建/复制回处理以重构RAID。在重建/复制时，控制器从一个磁盘读取数据并将数据写入另一个磁盘，因此会判断是否存在正常I / O，并且当缺少正常I / O时，读取和写入这些不同的磁盘驱动器同时执行。由此，可以减少重建/复制的时间。

摘要： The present invention has been made to obtain a magnetic disk apparatus and the like capable of using a patrol region in the magnetic disk to detect a location in need of maintenance in hardware equipment around the magnetic disk in a separate manner from the disk itself and thereby avoiding useless replacement and operating the magnetic disk apparatus at low cost. In a preventive maintenance detection for a magnetic disk apparatus having a patrol function that uses a patrol region in the magnetic disk to determine the presence/absence of the need of preventive maintenance, a data pattern for detecting crosstalk in hardware equipment around the disk is generated, a write command or read command corresponding to the generated data pattern is executed, and the crosstalk is determined/detected based on the command execution result.

摘要： A RAID system access a physical disk according to a host I/O request, and perform Rebuild/Copy back processing, for implementing high-speed Rebuild/Copy back processing without interrupting the processing of a normal I/O. When one disk device out of a plurality of disk devices constituting the RAID configuration fails, the processing size for one time of Rebuild/Copy back to reconstruct the RAID is changed according to the presence of a normal I/O managed in RAID control. When a normal I/O is present, Rebuild/Copy back can be executed without interrupting the processing of the normal I/O, and in a static state where a normal I/O is absent, a processing size larger than the size in that state can be specified so as to implement Rebuild/Copy back processing at high-speed.
