Patent number: 10671585Abstract: A method begins by a dispersed storage (DS) processing module storing a data portion in a dispersed storage network (DSN), where the data portion is associated with a set of data index keys, a version index key, and with a set of portion index keys. The method continues with the DS processing module traversing, based on the set of data index keys, a plurality of index structures to determine whether an object retrieval structure exists for the data portion. When the object retrieval structure exists, the method continues with the DS processing module updating the object retrieval structure by determining whether a version record exists that corresponds to the version index key and when the version record exists, creating, within the version record, a new data portion record for the data portion to include an identifier of the data portion and the set of portion index keys.Type: GrantFiled: July 16, 2013Date of Patent: June 2, 2020Assignee: Pure Storage, Inc.Inventors: Greg Dhuse, Ilya Volvovski, Adam Michael Gray, Andrew Baptist

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.

Patent number: 10089344Abstract: A method begins by a dispersed storage (DS) processing module receiving a request for a data index list that identifies data objects having one or more common attributes, searching a hierarchical ordered index structure to identify a data object level index node corresponding to a first data object boundary match, and determining whether the data object level index node corresponds to a second data object boundary match. When the data object level index node does not correspond to the second data object boundary match, the method continues with the DS processing module searching an adjacent data object level index node to determine whether the adjacent data object level index node corresponds to the second data object boundary match. When the adjacent data object level index node corresponds to the second data object boundary match, the method continues with the DS processing module generating the data index list.Type: GrantFiled: February 25, 2013Date of Patent: October 2, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Greg Dhuse, Wesley Leggette, Adam Michael Gray, Ilya Volvovski, Andrew Baptist

Patent number: 10013444Abstract: A method begins by a dispersed storage (DS) processing module determining to create or modify a data object index key of a data object regarding an attribute of a plurality of attribute categories. The method continues with the DS processing module entering a process to update a data object level index node by retrieving the data object level index node from a set of dispersed storage (DS) units. The method continues with the DS processing module updating and encoding the data object level index node to produce a set of slices. The method continues with the DS processing module generating a set of write commands to write the set of slices to the set of DS units. When less than a threshold number of the set of write commands are successfully executed by the set of DS units, repeating the process to update the data object level index node.Type: GrantFiled: February 25, 2013Date of Patent: July 3, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Greg Dhuse, Wesley Leggette, Adam Michael Gray, Ilya Volvovski, Andrew Baptist, Jason K.

Patent number: 9542239Abstract: A method to resolve conflicts arising from substantially concurrent write requests regarding a data object begins by a computing device of a dispersed storage network (DSN) issuing a write request for a dispersed storage error encoded version of the data object to storage units of the DSN. The method continues with the computing device receiving write responses, each including either a lock indication or a non-lock indication and conflict information. The method continues with the computing device determining whether at least a write threshold number of received write responses include the lock indication. When less than the at least a write threshold number of write responses have been received that include the lock indication, the method continues with the computing device processing the conflict information to identify one or more other write requests that have a higher priority than the write request and establishing a write request retry time frame.Type: GrantFiled: March 4, 2015Date of Patent: January 10, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Adam Michael Gray, Jason K.
