Publication number: 20170132100Abstract: Provided are a computer program product, computer system, and method for smart selection of a storage module to be excluded when a connection between two storage modules is broken. An indication is received from a first storage module that a connection between the first storage module and a second storage module is broken. In response to determining that the second storage module is accessible, values of exclusion criteria for the first storage module are determined and summed to identify a first exclusion total. Then, values of exclusion criteria for the second storage module are determined and summed to identify a second exclusion total. In response to determining that the first exclusion total exceeds the second exclusion total, the second storage node is excluded from the cluster. In response to determining that the second exclusion total exceeds the first exclusion total, the first storage node is excluded from the cluster.Type: ApplicationFiled: November 10, 2015Publication date: May 11, 2017Inventors: Michael Keller, Ofer Leneman, Osnat Shasha, Lior Shlomov, Ariel Waizel

Publication number: 20170131853Abstract: Provided are a computer program product, system, and method for generating a configuration page for rendering in a graphical user interface (GUI) for managing provisioning of storage resources in a storage system. A determination is made of allocation commitment certainties for virtual storage ranges to allocate from the storage system based on physical capacity in the storage system and an estimated data reduction rate. Each of the allocation commitment certainties indicates a likelihood that a corresponding of the virtual storage ranges will be available for allocation in the storage system. Visual representation of a plurality of user selectable storage spaces indicating the allocation commitment certainties for the virtual storage ranges in the user selectable storage spaces are rendered in the configuration page. A user selection graphic that when selected provisions a selected of the user selectable storage spaces in the storage system is rendered in the configuration page.Type: ApplicationFiled: November 10, 2015Publication date: May 11, 2017Inventors: Michael Keller, Ofer Leneman, Yoni Raveh, Gal Sinay, Moshe Weiss

Publication number: 20170085641Abstract: Provided are a computer program product, system, and method for distributed global data vaulting in a grid of server computers. At each of the server computers, it is determined that there is a system shutdown. For each data element at that server computer, a list of one or more vault devices at other server computers is retrieved from a vault distribution table, and the data element is dumped to the one or more vault devices at the other server computers.Type: ApplicationFiled: September 22, 2015Publication date: March 23, 2017Inventors: Daniel Gan-Levi, Ehood Garmiza, Michael Keller, Ofer Leneman

Efficient calculation of similarity search values and digest block boundaries for data deduplication
Patent number: 9600515Abstract: For efficient calculation of both similarity search values and boundaries of digest blocks in data deduplication, input data is partitioned into chunks, and for each chunk a set of rolling hash values is calculated. A single linear scan of the rolling hash values is used to produce both similarity search values and boundaries of the digest blocks of the chunk. The rolling hash values are used to contribute to the calculation of the similarity search values and to the calculation of the boundaries of the digest blocks.Type: GrantFiled: December 16, 2015Date of Patent: March 21, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H.

Patent number: 9547662Abstract: For digest retrieval based on similarity search in deduplication processing in a data deduplication system using a processor device in a computing environment, input data is partitioned into fixed sized data chunks. Similarity elements and digest block boundaries and digest values are calculated for each of the fixed sized data chunks. Matching similarity elements are searched for in a search structure containing the similarity elements for each of the fixed sized data chunks in a repository of data. Positions of similar data are located in the repository. The positions of the similar data are used to locate and load into the memory stored digest values and corresponding stored digest block boundaries of the similar data in the repository. The digest values and the corresponding digest block boundaries of the input data are matched with the stored digest values and the corresponding stored digest block boundaries to find data matches.Type: GrantFiled: March 15, 2013Date of Patent: January 17, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H.

Patent number: 9454591Abstract: Subsequent to a storage operation performed on the source instance by a source component, a synchronization message is sent to a replicated component for the replicated instance. The synchronization message is stored locally in a persistent storage location associated with the source component along with an indicator representative of a time the storage operation was performed. Pursuant to receipt of the synchronization message by the replicated component, the replicated component is updated to a dirty state to indicate a lack of full synchronization between the source and replicated instances.Type: GrantFiled: February 27, 2013Date of Patent: September 27, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H.

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: 8880482Abstract: Various embodiments for replicating deduplicated data using a processor device are provided. A block of the deduplicated data, created in a source repository, is assigned a global block identifier (ID) unique in a grid set inclusive of the source repository. The global block ID is generated using at least one unique identification value of the block, a containing grid of the grid set, and the source repository. The global block ID is transmitted from the source repository to a target repository. If the target repository determines the global block ID is associated with an existing block of the deduplicated data located within the target repository, the block is not transmitted to the target repository during a subsequent replication process.Type: GrantFiled: January 2, 2013Date of Patent: November 4, 2014Assignee: 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.
