Abstract
Described are techniques for performing data storage optimizations. A reserved workload for a first of a plurality of storage tiers is determined. Each of the plurality of storage tiers is characterized by a set of one or more attributes. The first storage tier includes performance characteristics which are any of incomplete, unknown, and unable to be predictively modeled for various workloads. The plurality of storage tiers includes the first tier and a remaining set of additional storage tier(s). Performance is modeled of a first workload distributed among the remaining set of storage tiers. The first workload represents a total workload less the reserved workload. One or more data movements are determined in accordance with the modeling. Each data movement moves a data portion from a first physical device of one of the plurality of storage tiers to a second physical device of another of the plurality of storage tiers.
