Patent number: 8850139Abstract: Exemplary system, and computer program product embodiments for changing ownership of cartridges, such as virtual cartridges between remotely located virtual tape libraries, are provided. In one embodiment, by way of example only, processes and protocols for the changing ownership of the cartridges are controlled from a primary location to a secondary location. The production site is moved for the cartridges. The ownership of the cartridges is waived. Access is allowed to the cartridges. Additional data is written and replicated using resources of the cartridges.Type: GrantFiled: May 11, 2011Date of Patent: September 30, 2014Assignee: International Business Machines CorporationInventors: Shay H. Akirav, Aviv Caro, Ofer Leneman, Itay Maoz, Uri Shmueli, Tzafrir Z. Taub

Patent number: 8719234Abstract: Methods, computer systems, and computer program products for deduplicating data are provided. Data is parsed to identify portions of metadata within the data. The data and identified portions of metadata are processed by a deduplication engine to be storable in a single repository. The deduplication engine is adapted for deduplicating the data without at least one of deduplicating and indexing the identified portions of metadata.Type: GrantFiled: January 25, 2012Date of Patent: May 6, 2014Assignee: International Business Machines CorporationInventors: Shay Haim Akirav, Aviv Caro

Patent number: 8671308Abstract: Exemplary system, and computer program product embodiments for optimizing disaster recovery systems during takeover operations are provided. In one embodiment, by way of example only, a flag is set in a replication grid manager to identify replication grid members to consult in a reconciliation process for resolving intersecting and non-intersecting data amongst the disaster recovery systems for a takeover operation. The replication grid members are consulted for the takeover operation to accommodate a coordination of an ownership synchronization process for cartridges not distributed on-time to the replication grid members. Additional system and computer program product embodiments are disclosed and provide related advantages.Type: GrantFiled: May 2, 2011Date of Patent: March 11, 2014Assignee: International Business Machines CorporationInventors: Shay H. Akirav, Aviv Caro, Itay Maoz, Gil E. Paz, Uri Shmueli, Tzafrir Z. Taub

Patent number: 8656215Abstract: Various embodiments for disaster recovery (DR) production takeover in a computing environment by a processor device are provided. If, for a designated storage system operable in the computing environment, a takeover operation may be executed, and a DR storage system has validly replaced the designated storage system using a replacement process, a withdrawal of a DR mode of operation is performed, and ownership of at least one storage device operable in the computing environment is transferred to the DR storage system. The replacement process authorizes the DR storage system to transfer the ownership while withdrawn from the DR mode of operation.Type: GrantFiled: February 12, 2013Date of Patent: February 18, 2014Assignee: International Business Machines CorporationInventors: Shay H. Akirav, Yariv Bachar, Aviv Caro, Dov N. Hepner, Ofer Leneman, Gil E. Paz, Tzafrir Z. Taub

Publication number: 20130325804Abstract: A unique file-system node identification (ID) is created for each newly created node in a file system repository by combining a grid identification (ID), a repository identification (ID), and a node identification (ID) to form the unique file-system node ID. The unique file-system node ID is associated with a unique association identification (ID) for creating an association for linking the node from a source repository to a target repository when performing a replication operation between a repository and another repository. The different replication instances of the node in the file system repository are distinguished by the unique association ID assigned to each of the replication instances.Type: ApplicationFiled: June 5, 2012Publication date: December 5, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Yariv BACHAR, Aviv CARO, Asaf LEVY, Oded SONIN

Publication number: 20130297971Abstract: Pursuant to execution of a predetermined failback policy, if a storage device is not preexistent in a source storage system operable in the computing environment, and an owner of the storage device is one of a DR storage system and a storage system having previously withdrawn from a replication grid, and the DR storage system has authorization to transfer ownership of the storage device by a replacement operation, and an instance of the storage device is replicated to the source storage system to generate a replicated instance of the storage device on the source storage system.Type: ApplicationFiled: July 9, 2013Publication date: November 7, 2013Inventors: Shay H. AKIRAV, Yariv BACHAR, Evgeny BUDILOVSKY, Aviv CARO, Elena DROBCHENKO, Dov N. HEPNER, Aharon LAZAR, Ofer LENEMAN, Itay MAOZ, Gil E. PAZ, Tzafrir Z. TAUB

Patent number: 8549348Abstract: For coordinated disaster recovery, a reconciliation process is performed for resolving intersecting and non-intersecting data amongst disaster recovery systems for takeover operations. An ownership synchronization process is coordinated for replica cartridges via the reconciliation process at the disaster recovery systems. The disaster recovery systems continue as a replication target for source systems and as a backup target for local backup applications.Type: GrantFiled: June 26, 2012Date of Patent: October 1, 2013Assignee: International Business Machines CorporationInventors: Shay H. Akirav, Aviv Caro, Itay Maoz, Gil E. Paz, Uri Shmueli, Tzafrir Z. Taub

Patent number: 8533407Abstract: A deduplication storage capacity is estimated as a function of an expected deduplication ratio, the expected deduplication ratio being a combined average of a current deduplication ratio and a configured deduplication ratio, the current deduplication ratio depending on the data currently stored in the deduplication storage, and the configured deduplication ratio being an estimate made at a configuration stage of the deduplication computing storage environment.Type: GrantFiled: December 1, 2010Date of Patent: September 10, 2013Assignee: International Business Machines CorporationInventors: Lior Aronovich, Shira Ben-Dor, Aviv Caro, Elena Drobchenko, Samuel Krikler, Ofer Leneman, Asaf Levy, Liran Loya, Dan Melamed, Tzafrir Z.

Patent number: 8423735Abstract: A calculated factoring ratio is determined as a weighted ratio of current nominal data to physical data based on at least one storage capacity threshold and a used storage space currently physically consumed by one of backup and replication data. A maximal nominal estimated space in the computing storage environment is calculated. A remaining space, defined as the maximal nominal estimated space minus a current nominal space in the computing storage environment, is calculated. If the remaining space is one of equal and less than a user-configured reservation space for backup operations, data replication operations are accepted and stored in the computing storage environment.Type: GrantFiled: May 21, 2010Date of Patent: April 16, 2013Assignee: International Business Machines CorporationInventors: Shay H.
