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.

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.

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 The replacement process authorizes the DR storage system to transfer the ownership while withdrawn from the DR mode of operation.Type: GrantFiled: February 12, 2013Date of Patent: February 18, 2014Assignee: International Business Machines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.
