    摘要： To optimize performance and power consumption of a storage system having many disk drives, the storage system contains a plurality of volumes. A first number of the volumes belong to a first volume set. The first number of the remaining volumes belong to a second volume set. The volumes that belong to the first volume set are allocated dispersedly to a second number of disk drives. The volumes that belong to the second volume set are allocated dispersedly to a third number of disk drives, the third number being larger than the second number. A computer selects one of the first volume set and the second volume set based on a predetermined condition to store data dispersedly in the volumes belonging to the selected volume set. The computer stops spinning of disks in the disk drives to which none of the volumes belonging to the selected volume set are allocated.

The multilink information list has fixed-length multilink information elements each indicting a number of links contained in a corresponding multilink. The road name information list has road name information elements each indicating a road name of corresponding multilink information element. The road name information elements are arranged in the road name information list in an order in which the corresponding multilink information elements are arranged in the multilink information list. The offset information list has fixed-length offset information elements each indicating location of a corresponding road name information element in the road name information list. The offset information elements are arranged in the offset information list in an order in which the corresponding multilink information elements are arranged in the multilink information list.
