Abstract:
A method for balancing load among virtual storage drives is disclosed. In one embodiment, such a method includes providing multiple storage drives and dividing each storage drive into multiple virtual storage drives. The method further creates RAID arrays from the virtual storage drives. Each RAID array is made up of extents that are striped across its virtual storage drives. The method tracks I/O to each virtual storage drive to determine which virtual storage drives have high I/O traffic and which virtual storage drives have low I/O traffic. The virtual storage drives are correlated to their respective RAID arrays. The method migrates extents from RAID arrays having virtual storage drives with high I/O traffic to RAID arrays having virtual storage drives with low I/O traffic. A corresponding system and computer program product are also disclosed.

Claim (Index 15):
A system for balancing load among virtual storage drives, the system comprising:\n at least one processor; at least one memory device operably coupled to the at least one processor and storing instructions for execution on the at least one processor, the instructions causing the at least one processor to:\n provide access to a plurality of physical storage drives; \n divide each physical storage drive into a plurality of virtual storage drives; \n create redundant array of independent disks (RAID) arrays from the virtual storage drives such that virtual storage drives on the same physical storage drive may be utilized in different RAID arrays, wherein each RAID array is made up of extents that are striped across its virtual storage drives; \n track input/output (I/O) to each virtual storage drive to determine which virtual storage drives have high I/O traffic and which virtual storage drives have low I/O traffic; \n correlate the virtual storage drives to their respective RAID arrays; and \n migrate extents from RAID arrays having virtual storage drives with high I/O traffic to RAID arrays having virtual storage drives with low I/O traffic.
