  • Patent number: 10148531
    Abstract: Implementations are provided herein for offering partitioned performance within a distributed file system and more specifically, for offering adaptive predicted impact of resource consumption by pending work items. Core resource consumption per work item can be estimated prior to processing the work item. When processing the work item, the actual amount of resources used to process the work item can be measured and recorded. The file system can then update future estimates for performing work items based on past results. Resources made available to process future requests can be throttled based on dynamically updated estimates of resource consumption by pending work items.

  • Patent number: 10148588
    Abstract: Implementations are provided herein for offering partitioned performance within a distributed file system and providing throttling at the granular level. A set of hardware and network resources available to process work items can be determined. A set of resource accounting tokens based on resource records generated when processing work items can be dynamically updated. A granular resource accounting aggregate for a customizable field of data can be selected for throttling, such as a unique user identifier, a unique group identifier, a unique client internet protocol address, a unique file, etc. A granular throttling level can then be established based on a granular throttling policy. In response to the resource accounting aggregate meeting the throttling level, the user, group, internet protocol address, etc. can be throttled at, at least one of, the cluster layer, the node layer or the protocol layer.

  • Patent number: 10142195
    Abstract: Implementations are provided herein for offering partitioned performance within a distributed file system. Core resource consumption per work item can be tracked independently. Discriminative data already known by the file system surrounding the context of the work item can be used to determine a reference resource accounting specification applicable to the work item. When processing the work item, a detailed resource record can be generated that inventories the resources used in processing the work item. The resource record associated with the work item can be recorded into a set of resource accounting tokens that track activity resource consumption at a granular level. A universal table of resource accounting tokens can be dynamically updated upon the processing of work items and generation of associated resource records throughout the distributed file system.

  • Patent number: 10033620
    Abstract: Implementations are provided herein for offering partitioned performance within a distributed file system; specifically, for providing adaptive policies and leases within the partitions. An amount of resources available to a cluster of nodes operating as a distributed file system can be determined and those resources can be apportioned to individual nodes based on hardware profiles of the nodes. A set of resource accounting tokens can be dynamically updated and used as a basis to generate a cluster resource accounting aggregate, a set of node resource accounting aggregates, and a set of protocol resource accounting aggregates. The dynamically updated resource accounting aggregates can then be used to dynamically throttle resource available to process work requests at the cluster, node, and protocol head layers based on policy.

  • Publication number: 20070245410
    Abstract: One embodiment of the present invention provides a system that facilitates securely forgetting a secret. During operation, the system obtains a set of secrets which are encrypted with a secret key Si, wherein the set of secrets includes a secret to be forgotten and other secrets which are to be remembered. Next, the system decrypts the secrets to be remembered using Si, and also removes the secret to be forgotten from the set of secrets. The system then obtains a new secret key Si+1, and encrypts the secrets to be remembered using Si+1. Finally, the system forgets Si.

  • Patent number: 7017012
    Abstract: In a computer system, a distributed storage system having a data coherency unit for maintaining data coherency across a number of storage devices sharing such data is described. The data coherency unit includes logic to monitor data transition states in each of the data storage devices to detect when the processing status of data being shared by two or more of the storage devices changes. The data coherency unit advantageously ensures a status change in shared data in one storage device is broadcast to other storage devices having copies of the data without having each storage device independently monitor adjourning storage devices to detect data state changes.
