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.

Abstract: One or more computing devices may comprise congestion management circuitry, one or more client file system request buffers, and DESS interface circuitry. The congestion management circuitry is operable to determine an amount of congestion in the DESS. 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, wherein the first priority level is higher priority than the second priority level. The DESS interface circuitry is operable to control a rate at which the first file system requests and second file system requests are fetched from the one or more client file system request buffers based on the amount of congestion in the DESS, on the first priority level, and on the second priority level.

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. Data communication is made more efficient by removing the need to copy data in the networking stack, using hardware accelerated end-to-end checksum calculation, and supporting transmission formatting of data and header for special cases.

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.

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.
