摘要： In this invention a logical record represents a record accessed by a HOST computer. A physical record represents a record defined on disk units. Physical records consist of data records and parity records. A data record has a value of a logical record. m data records and n parity records form parity records. Parity records are utilized to recover the contents of the data records which belong to the same parity group. A reduction in the generation times of updated values of parity records is realized. A data value of parity records has an allocated status to a logical record and an unallocated status. When a parity-generation scheduling unit decides generation of updated values of a parity group, it recognizes data records which are unallocated to logical records in the parity groups. Then it searches the logical records which are allocated to data records included in the other parity group. Finally it reallocates the recognized data records to the searched logical records. By reallocating data records to logical records, it becomes possible to reduce the number of the parity groups having data records allocated to logical records with updated values.
摘要翻译：在本发明中，逻辑记录表示由HOST计算机访问的记录。物理记录表示在磁盘单元上定义的记录。物理记录由数据记录和奇偶校验记录组成。数据记录具有逻辑记录的值。 m个数据记录和n个奇偶校验记录形成奇偶校验记录。奇偶校验记录用于恢复属于同一奇偶校验组的数据记录的内容。实现奇偶校验记录更新值的生成时间的减少。奇偶校验记录的数据值具有逻辑记录和未分配状态的分配状态。当奇偶校验生成调度单元决定奇偶校验组的更新值的生成时，它识别未分配给奇偶校验组中的逻辑记录的数据记录。然后，它搜索分配给包括在其他奇偶校验组中的数据记录的逻辑记录。最后，将识别的数据记录重新分配到搜索到的逻辑记录。通过将数据记录重新分配到逻辑记录，可以减少具有分配给具有更新值的逻辑记录的数据记录的奇偶校验组的数量。

摘要： A storage controller comprising a storage device adapter, a channel adapter, a cache memory, a control memory, and a plurality of buses connecting therebetween. The channel adapter communicates with a processor and processes input/output requests issued by the processor. The storage device adapter controls a storage device and data transfer between the storage device and the cache memory. The channel adapter and the storage device adapter exchanges control information via the control memory. The buses are used to transfer the data and the control information between the cache memory and the control memory, and the channel adapter and the storage device adapter. The controller also comprises bus load estimating means and bus mode selecting means. The bus load estimating means estimates bus load characteristics as an index based on the amount of data transfer during sequential access to the storage device. The bus mode selecting means determines a bus mode of bus utilization based on the index. Each of the channel adapter and the storage device adapter has bus access means for accessing the buses in accordance with the bus mode selected by the bus mode selecting means.

摘要： A storage control unit is connected between a central processing unit having an interface for accessing a first disk unit into which data constructed of a plurality of variable length data records are stored in a first recording format, and a second disk unit into which data constructed of a plurality of fixed length data blocks are recorded in a second recording format. The storage control unit contains a plurality of first-level storage regions having a storage capacity equal to a track of the first disk unit, and the first-level storage regions have a plurality of cache memories constructed of a plurality of second-level storage regions having storage capacities equal to the fixed length blocks in the second recording format. In response to a data update request issued from the central processing unit, a control processor within the storage control unit judges whether or not the data of the fixed length data blocks containing the data records to be updated in the first recording format, are present in each of these cache memories. When there is such a cache memory having no data, the data of the fixed length data blocks containing the variable length data records to be updated are stored into this cache memory.
