To efficiently assign storage resources to storage areas in a well-balanced manner in terms of performance and capacity, provided is a storage system in which, for a storage apparatus including a disk array group providing a logical volume to be assigned to an application, a storage management unit holds the throughput, response time, and storage capacity of the array group; receives performance density being a ratio between a throughput and a storage capacity, and a requirement on a storage capacity required for the logical volume; and assigns the throughput to the logical volume on the basis of the received performance density and the capacity requirement with the throughput of the array group set as an upper limit, and assigns, to the logical volume, a storage area determined on the basis of the assigned throughput and the received capacity requirement.
