  • Method and apparatus for power-managing storage devices in a storage pool
    Patent number: 7840657
    Abstract: A method for power-managing storage devices in a storage pool involves monitoring the storage pool to determine whether a storage management policy is satisfied, where the storage pool comprises a first storage device that is powered up and a second storage device that is powered down, powering up the second storage device after the storage management policy is satisfied, and making the second storage device available for use in the storage pool after the second storage device is powered up.
    Type: Grant

  • Method and system for reallocating blocks in a storage pool
    Patent number: 7783847
    Abstract: A method for reallocating blocks in a storage pool involves copying multiple source blocks to multiple replacement blocks, where the source blocks are stored on a source disk in the storage pool, and where the replacement blocks are stored on one or more replacement disks in the storage pool, and generating an indirection object, where the indirection object includes a mapping of locations of the source blocks to locations of the replacement blocks.

  • Method and system for priority-based allocation in a storage pool
    Patent number: 7584229
    Abstract: A method for priority-based allocation in a storage pool involves receiving a request to write a data item in the storage pool, where the storage pool includes multiple metaslabs, and where each of the metaslabs includes a contiguous region of data. The method further involves determining a target metaslab selected from the multiple metaslabs by comparing multiple allocation priorities, where each of the allocation priorities is associated with one of the metaslabs, allocating a block to the target metaslab, and writing the block to the target metaslab, where the block includes a portion of the data item.
