Abstract:
Provided is a computer system provided with an operation server in which a VM executing an application is operated, and a storage server. The operation server has a cache device, and the application executed on the VM performs processing by using a database structured by using a virtual memory assigned to the VM. The operation server has a virtualization control unit. The virtualization control unit has a memory access monitoring unit for monitoring memory access and an IO request issuing unit that generates an IO request, the memory access monitoring unit having monitoring policy management information for managing a monitoring policy including a physical address of the virtual memory and an acquisition policy indicating a method for reading data from the storage server. The memory access monitoring unit, upon detection of a memory access including the physical address of the virtual memory registered in the monitoring policy management information, instructs the IO request issuing unit to generate an IO request.
