1. A computer-implemented method of optimizing assignment, without disruption to applications, of data storage resources in a data storage arrangement having a plurality of pools, each pool comprising a plurality of data storage resources arranged in tiers and controlled by a Redundant Array of Inexpensive Disks (RAID) controller, the method comprising:

  • performing, by a processor, a gap analysis for a plurality of tiers of a plurality of pools, the gap analysis including a comparison of performance capacity versus performance demand for each tier of the plurality of tiers of the plurality of pools, the gap analysis also determining an extent to which tiers of pools have, relative to a standard data storage response time performance metric, excess performance capacity and excess performance demand, measured over a set period of time;

    modeling, by a processor, an effect of switching data storage resources from a first pool tier to a second pool tier in terms of the effect of the switch on excess performance capacity and excess performance demand;

    determining, by a processor, an improved arrangement of data storage resources in the first pool tier and the second pool tier that reduces excess performance capacity and excess performance demand, based on the modeling of the effect of switching data storage resources between pools; and

    switching at least one data storage resource from the first pool tier to the second pool tier based on the modeling.
