Patent number: 9634522Abstract: A method for identifying conditions that correlate with one ore more events related to operation of a power grid. The method includes the determining one or more distinguishing characteristics of a first chunk. The first chunk includes data elements relevant to operating a power grid. The method also includes determining whether a distinguishing characteristic of the first chunk correlates with a distinguishing characteristic of one or more of a plurality of second chunks. Each second chunk includes a plurality of data elements corresponding with the data of the first chunk. The method further includes determining whether a second chunk, having a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk, is associated with the one or more events.Type: GrantFiled: September 19, 2012Date of Patent: April 25, 2017Assignee: International Business Machines CorporationInventors: Allen K. Bates, Dov N. Hepner, Daniel J. Winarski

Patent number: 9442665Abstract: A calculated factoring ratio is determined as a weighted ratio of current nominal data to physical 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. Data replication operations are accepted and stored in the computing storage environment if the remaining space is below a predetermined threshold of space for backup operations.Type: GrantFiled: November 2, 2015Date of Patent: September 13, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H. Akirav, Aviv Caro, Elena Drobchenko, Asaf Ekshtein, Dov N. Hepner, Ofer Leneman, Tzafrir Z. Taub

Patent number: 9201605Abstract: 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.Type: GrantFiled: December 11, 2012Date of Patent: December 1, 2015Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H.

Patent number: 9189338Abstract: 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: GrantFiled: July 9, 2013Date of Patent: November 17, 2015Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: 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: 8806162Abstract: Visibility of a data storage entity on a first storage system is switched to a replicated data storage entity on a second storage system. Data from the data storage entity is replicated from the first storage system to the second storage system using a common serial number. The data storage entity is hidden from the first storage system by concealing the common serial number. An ejection of the data storage entity from the first storage system is automated, and the replicated data storage entity is introduced to the second storage system.Type: GrantFiled: May 8, 2012Date of Patent: August 12, 2014Assignee: International Business Machines CorporationInventors: Shay H. Akirav, Shiri Alexander, Yariv Bachar, Evgeny Budilovsky, Elena Drobchenko, Asaf K. Ekshtein, Dov N. Hepner, Aharon Lazar, Ofer Leneman, Itay Maoz, Gil E. Paz, Tzafrir Z. Taub, Neville Yates

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

Patent number: 8484503Abstract: Communication is arrested between a source data entity and a replicated data entity at a location declared in a DR mode. The DR mode is negotiated to a central replication management component as a DR mode entry event. The DR mode entry event is distributed, by the central replication management component, to each member in a shared group. The DR mode is enforced using at least one replication policy.Type: GrantFiled: August 18, 2010Date of Patent: July 9, 2013Assignee: International Business Machines CorporationInventors: Shay H.

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.
