1. A computer system, comprising:
a service server on which an application for carrying out predetermined processing operates; a storage server for storing data used by the application; and a management server for managing the service server and the storage server, the service server including a first processor, a first memory coupled to the first processor, a cache device which is coupled to the first processor, and to which a server cache for temporarily storing data is set, and a first interface coupled to the first processor for coupling to another apparatus, the storage server including a second processor, a second memory coupled to the second processor, a second interface coupled to the second processor for coupling to another apparatus, and a plurality of storage devices, the management server including a third processor, a third memory coupled to the third processor, and a third interface coupled to the third processor for coupling to another apparatus, the service server including: an operating system for controlling the service server, the operating system including a cache driver for controlling the server cache; and an I/O request monitoring unit for monitoring an I/O request issued by the application, and issuing a dummy I/O request for controlling an arrangement of data in the server cache in a case where a predetermined condition is satisfied, the management server including a cache optimization unit for generating a control policy for issuing the dummy I/O request, and setting the control policy to the I/O request monitoring unit, the cache optimization unit being configured to instruct the service server to carry out processing, the I/O request monitoring unit being configured to: monitor the I/O request issued by the application operating on the service server; and transmit monitoring information including an address of data of an access destination included in the I/O request and an identifier of an application that has issued the I/O request to the cache optimization unit in a case where the I/O request is detected, the cache optimization unit being configured to analyze the monitoring information and generate the control policy. |
