Abstract:
According to one aspect, the subject matter described herein includes a method for controlling prioritization of tiering and spin down features in a data storage system. The method is performed at a data storage array comprising a plurality of physical data storage disks for storing data and includes identifying data that is infrequently accessed. The infrequently accessed data is relocated to a subset of the physical data storage disks designated for storing infrequently accessed data and the spin rate of the subset of the disks is reduced.
