Abstract
To facilitate the management of a storage system that uses a flash memory as a storage area. A controller of the storage system provided with a flash memory chip manages a surplus capacity value of the flash memory chip, and transmits a value based on the surplus capacity value to a management server, on the basis of at least one of a definition of a parity group, a definition of an internal LU, and a definition of a logical unit. The management server displays a state of the storage system by using the received value based on the surplus capacity value.
