PROBLEM TO BE SOLVED: To provide a high-speed memory device of a high-speed DRAM resource or the like inside a storage system, for an external computer.SOLUTION: A computer system includes: a computer which includes an internal memory and an external memory, the external memory being provided by the storage system connected to the computer; and a controller which manages a virtual memory space comprising the internal memory and the external memory. The controller is operated so as to add a logical unit provided by the storage system to the external memory included in the virtual memory space on the basis of a use amount level of the virtual memory space. The controller is operated so as to release the logical unit provided by the storage system from the external memory included in the virtual memory space on the basis of the use amount level of the virtual memory space. |
