摘要： Buffers are separately provided for a region for non-sequential transfer and for a region for sequential transfer in each one of the disk units. A director sends a message to inform at least one of the disk units whether transfer of data the respective disk units are to make is sequential or non-sequential. When the disk unit receives a non-sequential transfer request, it uses the buffer region for non-sequential transfer to transfer data requested by the director and when it receives a sequential transfer request, it uses a plurality of buffer regions for the sequential transfer. Thus, data transfer is performed between a host device and that disk unit.

摘要： A buffer memory capable of storing contents of a plurality of tracks of a disk volume is provided in a disk controller or a disk drive, and in dump processing requested by a higher rank unit (CPU) to the disk controller, the data is immediately transferred from the buffer memory if the data to be dumped is present in the buffer memory, and if the data to be dumped is not present in the buffer memory, dump prefetching into the buffer memory is started and the execution of the dump processing is interrupted so that an on-line input/output operation other than the dump processing is accepted. When the dump prefetching into the buffer memory is over, the interrupted dump processing is resumed.

摘要： A buffered peripheral system comprises a backup memory and a primary control unit which has a buffer memory for temporarily storing a copy of the contents of a buffer memory which stores data to be written to a peripheral device and a control device for issuing a command necessary to write the block stored in the buffer memory device to the peripheral device. The primary control unit also includes a recording device for recording the block number corresponding to the block which was most recently written to the peripheral device. The blocks of data which have been written to the peripheral device is then deleted from the backup memory to make room for storing further blocks of data. The system further has a backup control unit substantially identical to the primary control unit. Only the primary control unit normally operates to control the writing to the peripheral device. Upon detection of the failure of the buffer memory in the primary control unit, the backup control unit completes the operation of writing to the peripheral device by retrieving the blocks of data to be written to the peripheral device from the backup memory device using the block number information.

摘要： In allocating an area of a cache memory to each storage unit, proper allocation of the cache memory is made to each storage unit. If the amount of write-after data becomes equal to or more than a threshold value, an allocation limit is set to each disk unit. If CPU issues a data write request requiring the amount of data equal to or more than the allocation limit, the data write request is held in a wait state until the amount of write-after data becomes less than the allocation limit. Therefore, the allocation amount to the disk unit becomes neither too large nor too small. In this manner, proper allocation of the cache memory to each disk unit can be realized.

摘要翻译： 在向每个存储单元分配高速缓冲存储器的区域时，对每个存储单元进行高速缓冲存储器的适当分配。 如果写入数据量等于或大于阈值，则对每个盘单元设置分配限制。 如果CPU发出数据写请求，要求数据量等于或大于分配限制，则数据写入请求将保持在等待状态，直到写入数据量小于分配限制为止。 因此，对于盘单元的分配量既不太大也不太小。 以这种方式，可以实现对每个盘单元的高速缓冲存储器的适当分配。
