摘要：The present disclosure describes a systems and methods for dynamic storage tiering A method for dynamic storage tiering may comprise: creating a point-in-time copy of a virtual volume including a storage hot-spot; copying a virtual volume segment including the hot-spot from a first storage pool to a second storage pool; and reconfiguring a logical block address mapping of the virtual volume to reference the virtual volume segment copy in the second storage pool. A system for dynamic storage tiering may comprise: means for creating a point-in-time copy of a virtual volume including a storage hot-spot; means for copying a virtual volume segment including the hot-spot from a first storage pool to a second storage pool; and means for reconfiguring a logical block address mapping of the virtual volume to reference the virtual volume segment copy in the second storage pool.
