ABSTRACT:
A computer system having a disk cache unit between a disk unit and the main storage unit. Ordinarily, the data transfer processing is carried out between the disk unit and the disk cache unit and between the disk cache unit and the main storage unit in this case. The present invention is characterized by enabling these two data transfer operations to be executed in parallel and to prevent a director from becoming the bottleneck of the processing due to the concentrated processing requests. For this purpose, the present invention provides for conducting a data transfer between the disk cache unit and a disk unit while a data transfer is taking place between the main storage unit and the disk cache unit. The director is configured, for example, with two data transfer controlling systems and two data transfer units for carrying out data transfer according to instructions for the two data transfer controlling systems.
