  • Patent number: 10402093
    Abstract: A distributed electronic storage system (DESS) comprises congestion management circuitry and data migration circuitry. The congestion management circuitry is operable to determine an amount of congestion in the DESS. The data migration circuitry is operable to control migration of data stored in a first tier of storage to a second tier of storage based on the amount of congestion in the DESS, characteristics of the data, and characteristics of the first tier of storage.

  • Patent number: 10394490
    Abstract: A plurality of computing devices are communicatively coupled to each other via a network, and each of the plurality of computing devices is operably coupled to one or more of a plurality of storage devices. A plurality of failure resilient address spaces are distributed across the plurality of storage devices such that each of the plurality of failure resilient address spaces spans a plurality of the storage devices. Each computing device is operable to maintain a two-level registry that records changes in the memory. When data is read from memory, recent changes to the data may be applied according to one or more corresponding registry blocks. Thus, the two-level registry enables the plurality of computing devices to postpone and/or consolidate writes to memory (e.g., non-volatile flash drives).

  • Patent number: 10268378
    Abstract: A system comprises a plurality of computing devices that are communicatively coupled via a network and have a file system distributed among them, and comprises one or more file system request buffers residing on one or more of the plurality of computing devices. File system choking management circuitry that resides on one or more of the plurality of computing devices is operable to separately control: a first rate at which a first type of file system requests (e.g., one of data requests, data read requests, data write requests, metadata requests, metadata read requests, and metadata write requests) are fetched from the one or more buffers, and a second rate at which a second type of file system requests (e.g., another of data requests, data read requests, data write requests, metadata requests, metadata read requests, and metadata write requests) are fetched from the one or more buffers.

  • Patent number: 10133516
    Abstract: One or more computing devices may comprise congestion management circuitry, one or more client file system request buffers, and DESS interface circuitry. The one or more client file system request buffers is/are operable to queue first client file system requests of a first priority level and second client file system requests of a second priority level, where the first priority level is higher priority than the second priority level. The DESS interface circuitry is operable to determine a choking level according to the load on a plurality of DESS resources. Individual load values of the DESS resources are mapped to a composite load value using a first function. The composite load value is mapped to a congestion contribution using a second function. And, the congestion contribution is mapped to a choking level using a third function.

  • Patent number: 9948705
    Abstract: A system comprises control circuitry that is operable to assign a first of a plurality of computing devices to serve file system requests destined for any of a first plurality of network addresses; assign a second of the computing devices to serve file system requests destined for any of a second plurality of network addresses; maintain statistics regarding file system requests sent to each of the first plurality of network addresses and the second plurality of network addresses; and reassign, based on the statistics, the first of the computing devices to serve file system requests destined for a selected one of the second plurality of network addresses.

  • Patent number: 9773013
    Abstract: A first computing device is part of a distributed electronic storage system (DESS) that also comprises one or more second computing devices. The first computing device comprises client process circuitry and DESS interface circuitry. The DESS interface circuitry is operable to: receive, from client process circuitry of the first computing device, a first client file system request that requires accessing a storage resource on one or more of the second computing devices; determine resources required for servicing of the first client file system request; generate a plurality of DESS file system requests for the first file system request; and transmit the plurality of DESS file system requests onto the one or more network links. How many such DESS file system requests are generated is determined based on the resources required for servicing the first client file system request.

  • Patent number: 9747162
    Abstract: A plurality of computing devices are communicatively coupled to each other via a network, and each of the plurality of computing devices comprises one or more of a plurality of storage devices. A plurality of failure resilient address spaces are distributed across the plurality of storage devices such that each of the plurality of failure resilient address spaces spans a plurality of the storage devices. Each one of the plurality of failure resilient address spaces is organized into a plurality of stripes. Each one or more stripes of the plurality of stripes is part of a respective one of a plurality of forward error correction (FEC) protection domains. Each of the plurality of stripes may comprise a plurality of storage blocks. Each block of a particular one of the plurality of stripes may reside on a different one of the plurality of storage devices.
