摘要： To enable power saving control by putting storage areas of the same attribute together in a specific RAID group in a storage apparatus that includes storage areas of different access patterns.The storage apparatus manages attributes of the RAID groups, which form a pool area, and attributes of the respective storage areas, based on an access log for each of the storage areas allocated to virtual volumes. The apparatus enables a power saving operation for each RAID group by putting the storage areas of each attribute together in a specific RAID group.
