Abstract:
1. A method comprising: detecting a storage hot-spot located in a first storage pool; creating a first point-in-time copy of a virtual volume including the storage hot-spot located in the first storage pool in a second storage pool according to the detecting; freezing the contents of the virtual volume including the storage hot-spot in the first storage pool; redirecting write requests directed to the virtual volume including the storage hot-spot located in the first storage pool to the point-in-time copy in the second storage pool; monitoring a ratio of storage hot-spot logical block addresses (LBAs) to low activity LBAs of the first point-in-time copy; and when the ratio reaches a pre-determined, user-configurable threshold, creating a second point-in-time copy including only the storage hot-spot LBAs of the first point-in-time copy.
