  • Patent number: 9075773
    Abstract: Embodiments are directed towards managing data storage that may experience a data failure. If a repair event is associated with a data storage failure, a new repair task may be generated and added to a task list. A priority value for each repair task in the task list may be determined based in part on the mean-time-to-data-loss (MTTDL) value associated with each repair task in the task list such that a lower MTTDL may indicate a higher priority value over a lower MTTDL. One or more repair tasks may be promoted to become active repair tasks based on the priority value the repair tasks such that the promoted repair tasks have a higher priority that than other repair tasks in the task list, if any. Each active repair task may be executed to repair one or more associated the storage failures.

  • Patent number: 9058334
    Abstract: A treewalk for splitting a file directory is disclosed for parallel execution of work items over a filesystem. The given work item is assigned to a worker. Thereafter, a request is sent to split the file directory to share a portion of the file directory with another worker. The worker examines the file directory for a next splittable directory entry key after a current in-progress location within a key space for the file directory. If no key is detected, the file directory is identified as unsplittable. If an entry is detected, the key space is progressively searched for a next entry between a next available directory entry key and an upper boundary. The worker identifies the file directory as splittable if the next available entry is found, providing a range of entries within the file directory for which parallel execution of the work item.

  • Patent number: 9053114
    Abstract: Embodiments are directed towards storing data in a storage system using an extensible data path. Data files may be provided to a caching tier in a storage system. If data files remain in the caching tier longer than a time limit, those data files may be removed from the caching tier and provided to a processing pipeline. The processing pipeline may be coupled to a capacity tier of the storage system. Filters to include in the processing pipeline may be determined based on the type of the data files. The data files may be updated based on applying each filter, such that each update corresponding to each filter may be cumulatively applied to each data file. Each updated data file may be stored in the capacity tier of the storage system after each filter in the processing pipeline has been applied.

  • Patent number: 8935567
    Abstract: Embodiments are directed towards a controller that provides individual network accessibility to a storage drive. The controller may include a first connector operative to couple with a storage-drive connector, a second connector operative to couple with a backplane connector of a multi-storage-drive chassis, memory, and processor. The controller may convert communication received through the first connector into an Ethernet protocol for output through the second connector, and convert communication received through the second connector into a storage-drive protocol for output through the first connector. A physical shape of the controller may fit adjacent to the storage-drive connector and occupy less space than is bounded by peripheral edges of an end of a separate housing of a storage drive coupled to the storage-drive connector. The controller may manage power provided to the storage drive and may coordinate with other controllers to manage power-up sequences of multiple storage drives.
