Patent number: 11445017Abstract: A computer-implemented method includes determining that an update to data on a local computer has been initiated by an application and sending a notification to a remote computer that the update has been initiated. The method includes sending, to the remote computer, an indication of the data on the local computer being updated. The method includes, in response to determining that updates to the data on the local computer and meta data corresponding to the data have been completed, sending a second notification to the remote computer that the update has been completed.Type: GrantFiled: February 21, 2019Date of Patent: September 13, 2022Assignee: International Business Machines CorporationInventors: Jeffrey R. Suarez, Nadim P. Shehab

Patent number: 11256716Abstract: Provided are a computer program product, system, and method verifying mirroring of source data units to target data units. Source data units in a source storage are mirrored to corresponding target data units in a target storage. The source data units are read to compare to corresponding mirrored target data units. The read source data units that did not match the corresponding target data units are saved in source version data. The source data units that were read and did not match the corresponding target data units are read. The mirroring of the source data units are verified in response to determining that for each mirrored source data unit, one of a read source data unit and the read source data unit saved in the source version data matches the corresponding target data unit.Type: GrantFiled: June 19, 2019Date of Patent: February 22, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: David Michael Shackelford, Nadim P. Shehab, John G. Thompson, Eduard Aaron Diel, Anthony H. Giang

Patent number: 11099942Abstract: An asynchronous remote copy relationship is maintained between primary storage volumes of a primary storage controller and secondary storage volumes of a secondary storage controller. A command is initiated to generate a point in time copy of a source volume of the primary storage controller to a target volume of the primary storage controller. A mirroring is performed of results of the point in time copy to the secondary storage controller to generate a source volume and a target volume in the secondary storage controller. Data from the target volume in the secondary storage controller is archived to a cloud storage.Type: GrantFiled: March 21, 2019Date of Patent: August 24, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Bard A. Doster, Nadim P. Shehab, Corey G. Smeaton, Max D. Smith

Patent number: 11023339Abstract: Provided are techniques for asynchronous remote mirror cloud archival. A data mover of a remote host receives, from an asynchronous remote mirror copy system of a primary storage controller, an archive copy operation, wherein the archive copy operation identifies a list of tracks of data and a location of cloud storage in a cloud infrastructure for storing the data from the tracks. The data mover issues, to a secondary storage controller, the archive copy operation, wherein the secondary storage controller archives the data from secondary storage to the cloud storage by invoking a cloud service, wherein the secondary storage stores data of primary storage of the primary storage controller.Type: GrantFiled: January 29, 2020Date of Patent: June 1, 2021Assignee: International Business Machines CorporationInventors: Corey G. Smeaton, Nadim P. Shehab, Max D. Smith, Bard A. Doster

Patent number: 9729629Abstract: A computer implemented method includes the steps of establishing a plurality of storage control sessions, wherein each storage control session associates at least one primary storage controller and at least one secondary storage controller with a predetermined path through a data transport network that interconnects the primary and secondary storage controllers; identifying storage control sessions that have data available to be transferred from primary storage controllers to secondary storage controllers; accumulating available data for each session and determining transfer time through the network for each data element to estimate prospective bandwidth utilization; and determining, for a predetermined time interval, whether transferring the available data would fully occupy available bandwidth of the data transport network for the predetermined time interval.Type: GrantFiled: January 21, 2014Date of Patent: August 8, 2017Assignee: International Business Machines CorporationInventors: Robert N. Crockett, Eduard A. Diel, Gregory E. McBride, Alan G. McClure, David M. Shackelford, Nadim P. Shehab

Patent number: 9720786Abstract: When the mirrored point in time copy fails, at that point in time all the data for making the source and target of the point in time copy consistent is available on secondary volumes at disaster recovery site. The data for the source and target of the failed point in time copy are logically and physically equal at that point in time. This logical relationship can be maintained, and protected against ongoing physical updates to the affected tracks on the source secondary volume, by first reading the affected tracks from the source secondary volume, copying the data to the target secondary volume, and then writing the updated track to the source secondary volume.Type: GrantFiled: April 22, 2014Date of Patent: August 1, 2017Assignee: International Business Machines CorporationInventors: Robert N.
