  • Patent number: 10877942
    Abstract: A software and hardware facility persistently maintains metrics on directories at different levels within a tree of a filesystem. The facility hierarchically aggregates attributes of files contained by directories and stores them as metric values in each directory within a tree. The stored values represent summed or otherwise aggregated data from the descendant directories and files. The metric values represent aggregated attributes such as checksums, MIN and/or MAX aggregates, sameness bits, bloom filter aggregates, queryable user tags, moving average aggregates, b-tree aggregates, etc. The facility provides mechanisms for efficiently sampling activities performed by the filesystem and visually representing these activities.
    Type: Grant

    Date of Patent: December 29, 2020
    Assignee: Qumulo, Inc.

  • Patent number: 8464161
    Abstract: An approach for managing permissions in a collaborative workspace involves providing a permissions user interface presentation without loosing a context associated with a collaborative workspace user interface presentation. The permissions user interface presentation visually organizes a set of workspace members into two or more permission level categories. The permissions user interface presentation also allows a user to efficiently add new workspace members from a local system or an alternative system.

    Abstract: An approach for managing permissions in a collaborative workspace involves providing a permissions user interface presentation without loosing a context associated with a collaborative workspace user interface presentation. The permissions user interface presentation visually organizes a set of workspace members into tow or more permission level categories. The permissions user interface presentation also allows a user to efficiently add new workspace members from a local system or an alternative system.
