摘要： An apparatus (12, 16) for recovering data in the case of single or double failures of N partial data blocks (D0, D1, D2, ...) generated by dividing the data where N is a natural number greater than 1. The apparatus recovers the data on the basis of a Galois field product computation table (20) including first and second search key data, and products of the first and second search key data. The first search key data includes possible symbol values. The second search key data includes a weighting value set and an inversed weighting value set. The weighting value set includes weighting values each assigned to one of the N partial data blocks and different from each other, and is closed under addition in the Galois field. The inversed weighting value set includes multiplicative inverses of the weighting values included in the weighting value set. In this way the size of the table (20) can be reduced.
摘要翻译：一种用于在通过划分数据而产生的N个部分数据块（D0，D1，D2，...）的一次或两次故障的情况下恢复数据的装置（12,16），其中N是大于1的自然数。装置基于包括第一和第二搜索关键数据的伽罗瓦域乘积计算表（20）以及第一和第二搜索关键数据的乘积来恢复数据。第一搜索关键字数据包括可能的符号值。第二搜索关键数据包括加权值组和反转加权值组。加权值组包括每个分配给N个部分数据块中的一个并且彼此不同的加权值，并且在Galois字段中在加法下关闭。反转加权值集合包括加权值集合中包含的加权值的乘法倒数。以这种方式可以减小表格（20）的大小。

摘要： A data storage subsystem that includes three data storage units, three check storage units, and an array controller coupled to the three data and three check storage units can tolerate failure of any three data and check storage units failures can be occur before data stored on the data storage subsystem is lost. Information is stored on the data storage subsystem as a symmetric Maximum Distance Separation code, such as Winograd code, a Reed Solomon code, an EVENODD code or a derivative of an EVENODD code. The array controller determines the contents of the check storage units so that any three erasures of the data storage units and the check storage units can be corrected by the array controller. The array controller updates a block of data contained in any one of the data storage units and the check storage units using only six IO operations.

摘要： PURPOSE: A high-speed destaging method using a parity engine is provided to minimize the affection of a response delay to total response performance, the delay being caused by the destaging, by using the blocks of a read cache, a write cache and a destaging cache in a cache memory. CONSTITUTION: After a read request is received from a host, the read cache block is checked(32). If a requested data does not exist in the read cache block, it is read from a disk to the read cache block(32a). When a write request is inputted, the write cache block and the destaging cache block are checked(33,35). If these blocks exist in the cache memory, the data received from a host is written in the blocks. If there is a data block allocatable to the write cache block in the cache memory(36), the data received from the host is written in the data block. If there is not the data block therein, one data block of the write cache block is moved to the destaging cache block(36a), so that one data block of the write cache block can be empty. Previous data and parity are read(36b), and thereby an intermediate parity is calculated(36c).
摘要翻译：目的：提供一种使用奇偶校验引擎的高速降级方法，以最小化响应延迟对总响应性能的影响，延迟是通过使用读缓存的块，写高速缓存和降级缓存在缓存中。构成：从主机接收到读取请求后，检查读取的缓存块（32）。如果读取缓存块中不存在所请求的数据，则从磁盘读取到读取高速缓存块（32a）。当输入写入请求时，检查写入高速缓存块和时序缓存块（33,35）。如果这些块存在于高速缓冲存储器中，则从主机接收的数据被写入块中。如果存在可分配给高速缓存存储器（36）中的写高速缓存块的数据块，则从主机接收的数据被写入数据块。如果其中没有数据块，则写入高速缓存块的一个数据块被移动到时序缓存块（36a），使得写入高速缓存块的一个数据块可以为空。读取先前的数据和奇偶校验（36b），由此计算中间奇偶校验（36c）。

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.

摘要： A redundant array of inexpensive disks (RAID) system includes a plurality of defect-adaptive memory devices for sequentially storing information needed for data recovery in a predetermined region of a recording medium in the form of block, and storing data in a region other than the predetermined region. A plurality of caches are connected to the adaptive memory devices to store information blocks needed for data recovery, the information blocks being read from a predetermined memory device. A controller is connected to each adaptive memory device and cache to control the writing and reading of data and information needed for data recovery in each memory device, calculate information needed for recovery of data read from each memory device, and store the information needed for recovery of data calculated in a predetermined cache.
