  • Patent number: 8560880
    Abstract: A disk drive system and method capable of dynamically allocating data is provided. The disk drive system may include a RAID subsystem having a pool of storage, for example a page pool of storage that maintains a free list of RAIDs, or a matrix of disk storage blocks that maintain a null list of RAIDs, and a disk manager having at least one disk storage system controller. The RAID subsystem and disk manager dynamically allocate data across the pool of storage and a plurality of disk drives based on RAID-to-disk mapping. The RAID subsystem and disk manager determine whether additional disk drives are required, and a notification is sent if the additional disk drives are required. Dynamic data allocation and data progression allow a user to acquire a disk drive later in time when it is needed. Dynamic data allocation also allows efficient data storage of snapshots/point-in-time copies of virtual volume pool of storage, instant data replay and data instant fusion for data backup, recovery etc.

  • Publication number: 20130145091
    Abstract: A method for dynamically balancing the allocation of data among a plurality of physical data storage devices having a plurality of RAID devices defined thereon, wherein at least one of the plurality of RAID devices is comprised of at least one of a different type of physical storage device or a different number of physical data storage devices than at least one other of the plurality of RAID devices, includes determining a usage factor unique to each RAID device and balancing data I/O based at least in part on the usage factor.

  • Publication number: 20130124798
    Abstract: The present disclosure relates to a data storage system including a RAID subsystem having a first and second type of RAID storage. A virtual volume configured to accept I/O is stored on the first type of RAID storage, and snapshots of the virtual volume are stored on the second type of RAID storage. A method of the present disclosure includes providing an active volume that accepts I/O and generating read-only snapshots of the volume. In certain embodiments, the active volume is converted to a snapshot. The active volume includes a first type of RAID storage, and the snapshots include a second type of RAID storage. The first type of RAID storage has a lower write penalty than the second type of RAID storage. In typical embodiments, the first type of RAID storage includes RAID 10 storage and the second type of RAID storage includes RAID 5 and/or RAID 6 storage.

  • Publication number: 20120290788
    Abstract: The present disclosure relates to systems and methods for RAID Restriping. One method includes selecting an initial RAID device for migration based on at least one score, creating an alternate RAID device, moving data from the initial RAID device to the alternate RAID device, and removing the initial RAID device. The method may be performed automatically by the system or manually. The method may be performed periodically, continuously, after every RAID device migration, upon addition of disk drives, and/or before removal of disk drives, etc. One system includes a RAID subsystem and a disk manager configured to automatically calculate a score for each RAID device, select a RAID device based on the relative scores of the RAID devices, create an alternate RAID device, move data from the selected RAID device to the alternate RAID device, and remove the selected RAID device.
