Data storage allocation utilizing virtual machine resource allocation

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• gather, by a data allocation mechanism, information pertaining to resource allocation to each partition in a set of partitions in a logically partitioned data processing system, the resource allocation to each partition indicating the number of processors, system memory units, and input/output adapters allocated to the partition;
• analyze, by the data allocation mechanism, the information to generate an allocated percentage of resources for each partition in the set of partitions in the logically partitioned data processing system;
• pass, by the data allocation mechanism, the allocated percentage of resources to a storage controller;
• and
• for each partition in the set of partitions in the logically partitioned data processing system:
• generate, by the storage controller, a storage partition in one or more faster storage tiers at a ratio according to the allocated percentage of resources associated with the partition, wherein each storage partition in each faster storage tier in the one or more faster storage tiers associated with each partition in the set of partitions in the logically partitioned data processing system is determined by multiplying a total of capacity of the faster storage tier by the allocated percentage of resources associated with the storage partition received from the data allocation mechanism;
• and
• migrate, by the storage controller, data between one or more slower storage tiers and the one or more faster storage tiers utilizing associated storage partitions in the one or more faster storage tiers generated by the storage controller.

An apparatus comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• gather, by a data allocation mechanism, information pertaining to resource allocation to each partition in a set of partitions in a logically partitioned data processing system, the resource allocation to each partition indicating the number of processors, system memory units, and input/output adapters allocated to the partition;
• analyze, by the data allocation mechanism, the information to generate an allocated percentage of resources for each partition in the set of partitions in the logically partitioned data processing system;
• pass, by the data allocation mechanism, the allocated percentage of resources to a storage controller;
• and
• for each partition in the set of partitions in the logically partitioned data processing system:
• generate, by the storage controller, a storage partition in one or more faster storage tiers at a ratio according to the allocated percentage of resources associated with the partition, wherein each storage partition in each faster storage tier in the one or more faster storage tiers associated with each partition in the set of partitions in the logically partitioned data processing system is determined by multiplying a total of capacity of the faster storage tier by the allocated percentage of resources associated with the storage partition received from the data allocation mechanism;
• and
• migrate, by the storage controller, data between one or more slower storage tiers and the one or more faster storage tiers utilizing associated storage partitions in the one or more faster storage tiers generated by the storage controller.
