The present invention manages response performance of a virtual volume. A performance monitoring server 10 monitors performance of a virtual volume 400, which a storage apparatus 40 provides to a host 30. When response performance of a virtual volume becomes lower than target performance, the performance monitoring server 10 creates and presents to a user either one or multiple solutions for improving the response performance. The user is able to issue an instruction based on the presented one or multiple solutions.
