  • Dynamic premigration throttling for tiered storage
    Patent number: 11086783
    Abstract: A dynamic premigration protocol is implemented in response to a secondary tier returning to an operational state and an amount of data associated with a premigration queue of a primary tier exceeding a first threshold. The dynamic premigration protocol can comprise at least a temporary premigration throttling level. An original premigration protocol is implemented in response to an amount of data associated with the premigration queue decreasing below the first threshold.
    Type: Grant
    Filed: October 10, 2019
    Date of Patent: August 10, 2021
    Assignee: International Business Machines Corporation
    Inventors: Koichi Masuda, Katja I. Denefleh, Joseph M. Swingler

  • Dynamically changing copy policy
    Patent number: 10353791
    Abstract: An approach for dynamically changing a copy policy associated with a cluster grid for tape storage virtualization which involves monitoring one or more statuses of a plurality of clusters associated with the cluster grid, wherein the one or more of the plurality of clusters are assigned one of a plurality of copy modes, detecting that at least one of the plurality of clusters, having a highest priority copy mode associated with the cluster grid, is unavailable, selecting an available second cluster of the plurality of clusters and changing the copy policy wherein the available second cluster is assigned the highest priority copy mode.
