Patent number: 8321721Abstract: 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.Type: GrantFiled: May 10, 2011Date of Patent: November 27, 2012Assignee: Compellent TechnologiesInventors: Philip E. Soran, John P. Guider, Lawrence E. Aszmann, Michael J. Klemm

Publication number: 20100037023Abstract: 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.Type: ApplicationFiled: August 7, 2009Publication date: February 11, 2010Inventors: Lawrence E.
