  • Selective space reclamation of data storage memory employing heat and relocation metrics
    Patent number: 10482032
    Abstract: Space of a data storage memory of a data storage memory system is reclaimed by determining heat metrics of data stored in the data storage memory; determining relocation metrics related to relocation of the data within the data storage memory; determining utility metrics of the data relating the heat metrics to the relocation metrics for the data; and making the data whose utility metric fails a utility metric threshold, available for space reclamation.
    Type: Grant
    Filed: April 12, 2018
    Date of Patent: November 19, 2019
    Assignee: International Business Machines Corporation
    Inventors: Michael T. Benhase, Evangelos S. Eleftheriou, Lokesh M. Gupta, Robert Haas, Xiao Y. Hu, Matthew J. Kalos, Ioannis Koltsidas, Roman A. Pletka
