ABSTRACT:
A computer system is provided with a collection section for collecting load information related to an application server and a storage subsystem, a transmission section for predicting a write processing property based on the load information collected by the collection section and for transmitting the write processing property to the storage subsystem, and a write control section for controlling a write processing to a hard disk drive in the storage subsystem based on the write processing property transmitted by the transmission section. A target of the writable cache amount is set so that a write processing amount from a cache of the storage subsystem to the hard disk drive is averaged in terms of time, and the write processing to the hard disk drive is performed to satisfy the target of the writable cache amount.
