Abstract: A computing system includes a computer in communication with a tiered storage system. The computing system identifies a set of data transferring to a storage tier within the storage system. The computing system identifies a program to which the data set is allocated and determines to increase or reduce resources of the computer allocated to the program, based on the set of data transferring to the storage tier. The computing system discontinues transferring the set of data to the storage tier if a resource allocated to the program cannot be increased.

Abstract: A mechanism is provided for allocating data storage utilizing virtual machine resource allocation. Information pertaining to resource allocation to a set of partitions in a logically partitioned data processing system is gathered and analyzed to generate resource allocation based storage information for each partition in the set of partitions in the logically partitioned data processing system. For each partition in the set of partitions in the logically partitioned data processing system, a storage partition is generated in one or more faster storage tiers at a ratio according to the resource allocation based storage information associated with that partition. For each partition in the set of partitions in the logically partitioned data processing system, data is migrated between one or more slower storage tiers and the one or more faster storage tiers utilizing associated storage partitions in the one or more fastest storage tiers.

Abstract: Various embodiments for managing data stored in a tiered data storage environment, by a processor device, are provided. A data file is proactively migrated from a lower tier to a higher tier of the tiered data storage environment by using a multidimensional algorithm adopting an actual frequency of access of the data file to gauge a slope of a predicted frequency of access of the data file. The data file is migrated from the lower tier to the higher tier only if each of a plurality of criteria of the multidimensional algorithm is satisfied.
