Patent number: 11010357Abstract: A method begins by a processing module of a dispersed storage network (DSN) determining a fault domain for a portion of the DSN and generating a local redundancy for the fault domain. The method continues with the processing module identifying storage locations available for storing the first local redundancy, selecting storage locations for storing the first local redundancy and continues with the processing module facilitating storage of the local redundancy in the storage locations. Upon detecting a storage failure in the DSN, the method continues with the processing module determining whether the storage failure is associated with the fault domain and in response determining whether the first local redundancy is associated with the first fault domain. In response to determining that the local redundancy is associated with the first fault domain the method continues with the processing module recovering the local redundancy and correcting the storage failure.Type: GrantFiled: October 4, 2018Date of Patent: May 18, 2021Assignee: PURE STORAGE, INC.Inventors: Ilya Volvovski, Bruno Hennig Cabral, Manish Motwani, Thomas Darrel Cocagne, Timothy W.

Patent number: 10416889Abstract: A method includes receiving, by a storage unit of a dispersed storage network (DSN) an access request for an encoded data a slice of a set of encoded data slices from a computing device of the DSN. The method further includes queueing, by the storage unit, the access request for the encoded data slice. The method further includes, prior to executing the access request, determining, by the storage unit, whether a session associated with the access request is still active and whether execution the access request for encoded data slice is still needed. When the session is still active and the execution of the access request for the encoded data slice is still needed, the method further includes executing, by the storage unit, the access request for the encoded data slice.Type: GrantFiled: November 22, 2017Date of Patent: September 17, 2019Assignee: PURE STORAGE, INC.Inventors: Andrew Baptist, Joseph Martin Kaczmarek, Yogesh Ramesh Vedpathak

Patent number: 10334046Abstract: A method begins by a dispersed storage (DS) processing module dividing a very large data object into a plurality of data regions and generating a data object storage tracking table that includes sections for identifying one or more data regions that are available or unavailable for retrieval. The method continues with the DS processing module dividing a first data region into data segments and disperse storage error encoding the data segments to produce sets of encoded data slices. The method continues with the DS processing module sending DSN write requests regarding storing the sets of encoded data slices to storage units and when at least a write threshold number of write responses is received for each of the sets of encoded data slices, updating the data object storage tracking table to indicate that the first data region is available for retrieval.Type: GrantFiled: July 21, 2016Date of Patent: June 25, 2019Assignee: International Business Machines CorporationInventors: Wesley Leggette, Jason K.
