  • Sub-lun input/output profiling for SSD devices
    Patent number: 10031696
    Abstract: A read/write ratio for each of a plurality of data segments classified in a hot category as hot data segments is determined. Each of the plurality of hot data segments is ordered by the read/write ratio in a descending order. Each of a plurality of available SSD devices is ordered by a remaining life expectancy in an ascending order. Those of the plurality of hot data segments are matched with those of the plurality of hot data segments with those of the plurality of available SSD devices such that a hot data segment having a higher read/write ratio is provided to an SSD device having a smaller remaining life expectancy than another hot data segment having a lower read/write ratio.
    Type: Grant
    Filed: November 17, 2017
    Date of Patent: July 24, 2018
    Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
    Inventors: Philip M. Dudas, Paul A. Jennas, II, Larry Juarez, David Montgomery, Jason L. Peipelman, Joshua M. Rhoades, Todd Sorenson
