Abstract: Embodiments of the present invention disclose a method, system, and computer program product for cost effective data storage. A computer stores and arranges data in data storage resources in compressed or uncompressed arrangements. The computer determines what percentage of data is stored per tier for an uncompressed arrangement of data. The computer further determines both a compression factor as well as the percentage of data stored per tier for data stored in the compressed arrangement. The computer accesses data defining the cost per tier of both the compressed and uncompressed arrangement of data, then calculates the cost of both a compressed and uncompressed arrangement of the data. The computer then moves the data to the less expensive of the compressed or uncompressed arrangement of the data.

Abstract: The assignment of data storage resources in a data storage arrangement having a plurality of pools, where each pool includes a plurality of data storage resources arranged in tiers, can be optimized. A gap analysis can be performed for each tier of each pool to determine that tier's excess capacity or demand. The effect of switching data storage resources between tiers of different pools can be modeled to determine the effect of the switch on excess capacity and demand. An improved arrangement of data storage resources in the tiers can be determined that reduces excess capacity and demand, from the modeling of the effect of switching data storage resources between pools. At least one data storage resource can be switched from the tier of the first pool to the tier of the second pool to match the determined improved arrangement of data storage resources.
