  • Dataset space reclamation
    Patent number: 11886707
    Abstract: Systems, methods, and computer readable storage mediums for discovering volumes which are good candidates for space reclamation. A storage subsystem identifies the file system storage capacity for a given volume from the file system metadata of the given volume. Then, the storage subsystem compares the file system capacity of the given volume to the allocated capacity on the storage subsystem. If the allocated capacity is greater than the file system capacity by a given threshold, the storage subsystem marks the given volume as a candidate for space reclamation and generates an alert to the user to reclaim the space of the given volume.

  • Managing host definitions across a plurality of storage systems
    Patent number: 10454810
    Abstract: Managing host definitions across a plurality of storage systems, including: creating, on a first storage system, a host definition describing a host that accesses a dataset that is replicated across a plurality of storage systems; determining whether a second storage system that the dataset is replicated across includes a definition of the host; responsive to determining that the second storage system does not include a definition of the host, copying the host definition created on the first storage system to the second storage system; responsive to determining that the second storage system does include a definition of the host: linking the host definition created on the first storage system to the definition of the host on the second storage system or retaining the definition of the host on the second storage system.
