Patent number: 11531493Abstract: The disclosed technology includes an example system that has a request throttling manager that is configured to receive a first file data request, queue the first file data request in a first request queue, and process the first file data request based on the first token bucket. The first token bucket includes a sufficient first quantity of first tokens to process the first file data request. The system further includes a storage manager configured to access one or more storage nodes of a plurality of storage nodes of a distributed storage system in response to the first file data request.Type: GrantFiled: December 19, 2019Date of Patent: December 20, 2022Assignee: Western Digital Technologies, Inc.Inventors: Arne Vansteenkiste, Sander De Dycker, Wim De Wispelaere, Joris Walraevens, Dieter Fiems, Willem Mélange, Apoorv Saxena

Patent number: 11409720Abstract: According to an example method, a read request associated with a second data object is received, where the second data object is identifiable by a second object identifier. A second segment index number is determined that would identify a location of the second data object is absent from a metadata index. In response to determining that the second segment index number is absent from the metadata index, an incrementally lower index is selected in the metadata index, where the incrementally lower index is a first segment index number that identifies a location of the first data object. The second data object is retrieved using the first segment index number and a first offset corresponding to the first segment index number.Type: GrantFiled: November 13, 2019Date of Patent: August 9, 2022Assignee: Western Digital Technologies, Inc.Inventors: Bruno Keymolen, Wim De Wispelaere

Patent number: 10725884Abstract: A method and computer device for storage and retrieval of a data object on a storage medium. The method includes steps of disassembling the data object into a predetermined number of redundant sub blocks, storing the redundant sub blocks on the storage medium, retrieving at least a predetermined multiple of a minimal spreading requirement of the redundant sub blocks from the storage medium, and assembling the data object from any combination of a particular number of the redundant sub blocks, the particular number corresponding to a predetermined multiple of a minimal spreading requirement. The computer device includes modules for performing the steps.Type: GrantFiled: December 13, 2017Date of Patent: July 28, 2020Assignee: Western Digital Technologies, Inc.Inventors: Frederik De Schrijver, Romain Raymond Agnes Slootmaekers, Bastiaan Stougie, Joost Yervante Damad, Wim De Wispelaere, Wouter Van Eetvelde, Bart De Vylder

Patent number: 10503420Abstract: A storage node for a distributed object storage system, comprising a control board configured to receive a parameter for setting predetermined allowable temperature ranges through a serial port, and sending a signal through said serial port for indicating one or more of said measurements of temperatures lies outside said predetermined allowable ranges. The control board is further configured to receive a parameter for controlling the switching on or off the storage elements through said serial port by sending a signal through said serial port to indicate which storage elements is switched on or off.Type: GrantFiled: November 13, 2017Date of Patent: December 10, 2019Assignee: Western Digital Technologies, Inc.Inventors: Kristof Mark Guy De Spiegeleer, Wim De Wispelaere
