POWER AND PERFORMANCE MANAGEMENT USING MAIDX AND ADAPTIVE DATA PLACEMENT

摘要

The present invention is a method for storing data. The method includes the step of dividing data into a plurality of uniformly-sized segments. The method further includes storing said uniformly-sized segments on a plurality of storage mechanisms. The method includes the steps of monitoring access to the uniformly-sized segments stored on the plurality of storage mechanisms to determine an access pattern; monitoring access patterns between the plurality of disks and monitoring performance characteristics of the plurality of storage mechanisms to determine a performance requirement for the plurality of storage mechanisms. Finally, the method includes the step of migrating at least one segment of the plurality of uniformly-sized segments from a first storage mechanism of the plurality of storage mechanisms to a second storage mechanism of the plurality of storage mechanisms in response to at least one of the access patterns or the performance requirements.
