SYSTEMS, METHODS, AND PHYSICAL COMPUTER STORAGE MEDIA TO OPTIMIZE DATA PLACEMENT IN MULTI-TIERED STORAGE SYSTEMS

摘要

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.
