Patent Images
1. An information system, comprising:
- a computer;
a storage system, which includes a flash memory device, a cache memory, and a storage controller storing storage configuration information, and which provides a logical unit to the computer by using the flash memory device; and
a management system managing the storage system and the computer,wherein the storage controller stores, in the storage configuration information, a first surplus capacity value that is based on a capacity of a surplus area of the flash memory device, generates storage management information based on the storage configuration information, and transmits the storage management information to the management system, andwherein the management system receives the storage management information, and displays a management surplus capacity value that relates to the storage system, based on the storage management information.

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.

13. A management system that manages a computer and a storage system that provides a logical unit to the computer using a flash memory device, the management system comprising:
-
a port receiving, from the storage system, a first surplus capacity value which is a value relating to a capacity of a surplus area of the flash memory device; a memory storing storage configuration information and management-side storage configuration information storing the first surplus capacity value; a processor monitoring the storage system using the port; and an input/output device displaying a state of the storage system using the management-side storage configuration information, wherein the processor generates a management surplus capacity value relating to the storage system on the basis of the management-side storage management information, and wherein the input/output device displays the management surplus capacity value. - View Dependent Claims (14)

15. A management method of a management system that manages a computer and a storage system that provides a logical unit to the computer using a flash memory device, the method comprising:
-
by the management system, receiving from the storage system a first surplus capacity value relating to a capacity of a surplus area of the flash memory device; by the management system, storing storage configuration information and management-side storage configuration information storing the first surplus capacity value; by the management system, generating a management surplus capacity value relating to the storage system on the basis of the management-side storage management information; and by the management system, displaying the management surplus capacity value by using an input/output device of the management system.
