DETERMINATION OF A TYPE OF DESTAGE TO PERFORM BASED ON PREFERENCE BETWEEN PERFORMANCE OF OPERATIONS AND PRESERVATION OF DRIVE LIFE USING A MACHINE LEARNING MODULE

Abstract:

A storage controller is configured to perform a full stride destage, a strip destage, and an individual track destage. A machine learning module receives a plurality of inputs corresponding to a plurality of factors that affect performance of data transfer operations and preservation of drive life in the storage controller. In response to receiving the inputs, the machine learning module generates a first output, a second output, and a third output that indicate a preference measure for the full stride destage, the strip destage, and the individual track destage respectively.
