  • Storage space reclaiming for virtual provisioning
    Patent number: 9558111
    Abstract: A reclaim system frees previously allocated, but currently unused, storage space in a thin or virtual provisioning environment. The reclaim system may be used in connection with a maintenance operation performed upon determining that significant allocated space of a thin device is no longer being used or may be performed periodically to analyze a thin device and free appropriate space back to a thin device storage pool. In an embodiment, the reclaim system may run online while user applications are accessing a target storage volume.
