20120303917 | SYSTEMS, METHODS, AND PHYSICAL COMPUTER STORAGE MEDIA TO OPTIMIZE DATA PLACEMENT IN MULTI-TIERED STORAGE SYSTEMS - A system includes a data collector, a plurality of data placement optimizers, a data placement arbitrator, and a data mover. The data collector is configured to collect system configuration data and system performance data. The plurality of data placement optimizers are each configured to analyze the system configuration data and the system performance data for developing a corresponding data movement plan. The data placement arbitrator is configured to arbitrate conflicts between at least two data movement plans of generated by the plurality of data placement optimizers to form an execution plan. The data mover is configured to perform the data movement plans according to the execution plan. | 11-29-2012 |
20120303929 | SYSTEMS, METHODS, AND PHYSICAL COMPUTER STORAGE MEDIA TO OPTIMIZE DATA PLACEMENT IN MULTI-TIERED STORAGE SYSTEMS - For optimizing data placement in a multi-tiered storage system, system configuration data and system performance data is collected. A plurality of data movement plans are generated, based in part on the system configuration data and the system performance data. A conflict between the plurality of data movement plans are arbitrated to form an execution plan. The data movement plans are performed according to the execution plan. | 11-29-2012 |
