Patent number: 11593162Abstract: A method of managing operation of a computing device is provided. The method includes (a) running a system scheduler that schedules execution of a first application and a second application on a central processing unit (CPU) core of the computing device; (b) while the first application is executing on the core, detecting, by the first application, a context-switch opportunity; and (c) issuing, by the first application in response to detecting the context-switch opportunity, a blocking operation that triggers the system scheduler to perform a rescheduling operation between the first and second applications on the CPU core. An apparatus, system, and computer program product for performing a similar method are also provided.Type: GrantFiled: October 20, 2020Date of Patent: February 28, 2023Assignee: EMC IP Holding Company LLCInventors: Lior Kamran, Amitai Alkalay, Liran Loya

Patent number: 11500556Abstract: A method for use in a first storage array, comprising: detecting whether a second storage array has designated the first storage array as a locally-preferred storage array, the detecting being performed when a first link between the second storage array and a witness node is down; setting a value of a first configuration setting to indicate that the first storage array is designated as a system-preferred storage array, the value of the first configuration setting being stored in a memory of the first storage array, the value of the first configuration setting being set only when the second storage array has designated the first storage array as a locally-preferred storage array; detecting, by the first storage array; and when the second link is down, assuming one of an active role or a passive role based, at least in part, on the value of the first configuration setting.Type: GrantFiled: April 23, 2021Date of Patent: November 15, 2022Assignee: EMC IP Holding Company LLCInventors: Sally Golan, Liran Loya, Yuval Harduf

Patent number: 10884670Abstract: Methods, computer systems, and computer program products for processing data a computing environment are provided. The computer environment for data deduplication storage receives a plurality of write operations for deduplication storage of the data. The data is buffered in a plurality of buffers with overflow temporarily stored to a memory hierarchy when the data received for deduplication storage is sequential or non sequential. The data is accumulated and updated in the plurality of buffers per a data structure, the data structure serving as a fragment map between the plurality of buffers and a plurality of user file locations. The data is restructured in the plurality of buffers to form a complete sequence of a required sequence size. The data is provided as at least one stream to a stream-based deduplication algorithm for processing and storage.Type: GrantFiled: February 14, 2018Date of Patent: January 5, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H.

Patent number: 10599535Abstract: A DSM component is organized as a matrix of page. The data structure of a set of data structures occupies a column in the matrix of pages. A recovery file is maintained in a persistent storage. The recovery file consists of entries and each one of the entries corresponds to a column in the matrix of pages by a location of each one of the entries. The set of data structures is stored in the DSM component and in the persistent storage. Incorporated into each one of the plurality of entries in the recovery file is an indication if an associated column in the matrix of pages is assigned with the data structure of the set of data structures; and additionally incorporated into each one of the plurality of entries in the recovery file are identifying key properties of the data structure of the set of data structures.Type: GrantFiled: November 22, 2017Date of Patent: March 24, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lior Aronovich, Asaf Levy, Liran Loya

Patent number: 10592453Abstract: Moving from a back-to-back topology to a switched topology in an InfiniBand network includes, prior to connecting a switch for a first storage controller in the network and during reboot of the first storage controller, waiting for a second storage controller in the network to become master, and upon the second storage controller becoming master, changing cache files for local ports on the first storage controller regarding adjacent ports' LID assignments. An aspect further includes restarting a system manager for the first storage controller, connecting the first storage controller to the system with new LID assignments provided by changed files on first storage controller, and upon the first storage controller becoming active, rebooting the second storage controller, changing the LID assignments in the active storage controller, and adding new switches to the system.Type: GrantFiled: August 1, 2018Date of Patent: March 17, 2020Assignee: EMC IP Holding Company LLCInventors: Ahia Lieber, Liran Loya, Alex Kulakovsky
