Abstract:
The storage system defines, a RAID group having one or more logical devices, and manages the logical devices by assigning them to a pool. When a data write request is received from the host for the virtual volume, the storage system allocates an unused logical storage area in the pool to the virtual volume and writes the data to the storage device having the allocated logical storage area. The storage device compresses the data, stores it in the physical area, and manages the physical area in association with the logical storage region. A computer system may increase the amount of the physical area assigned to the pool when a physical usage amount of the physical area belonging to the pool exceeds a predetermined threshold value, and increase the amount of the logical storage area assigned to the pool when the logical usage amount exceeds a predetermined threshold value.

Claim (Index 4):
The computer system of  claim 2 , wherein:\n when increasing the amount of the logical storage area, the computer system is further configured to preferentially add to the pool, from among the RAID groups having logical devices assigned to the pool, logical devices included in a RAID group whose total of the logical devices already assigned to the pool is greater than or equal to a real capacity of the RAID group; and the real capacity of the RAID group is a total of the physical areas of the storage devices belonging to the RAID group.
