description A method for Dynamic Storage Tiering (DST) may include identifying a first storage tier with a performance characteristic. The method may include monitoring the utilization of the first storage tier to detect the placement of a hot spot. The method may include logically dividing a continuous range of a plurality of logical addresses into at least a first segment and a second segment so the first segment includes a proportionally larger amount of the hot spot. The method may include moving the first segment into a second storage tier or moving the second segment into the second storage tier. The method may include determining an amount of utilization of the first storage tier by hot spots. The method may include recommending a change in an amount of storage space in the first storage tier based upon the amount of utilization of the first storage tier by the hot spots.
