Abstract
A computer-implemented method (CIM), according to one embodiment, includes obtaining application data associated with interaction of applications of host servers that use a data storage system and using the application data to predict performance requirements for the applications with respect to the data storage system. The method further includes maintaining a persistent control repository having parameter fields. A first and second of the parameter fields detail, for extents of data stored in tiers of the data storage system, associated ranges of acceptable performance targets, and a third and fourth of the fields detail, associated arrival times for requests from the applications for the extents of data. The method further includes using the persistent control repository to calculate heat weights for the extents of data, and causing a tiering manager to adjust a current tiering of the extents of data in the tiers based on the calculated weights.
