Patent number: 10320707Abstract: Embodiments for performance management in a computing storage environment. In a storage system having a predetermined number of available quality of service (QoS) values associated with a performance of the storage system, the predetermined number of available QoS values are spread over a range such that a user requested QoS value is matched with one of the available QoS values within an optimal deviation value to a given precision.Type: GrantFiled: October 31, 2016Date of Patent: June 11, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ohad Atia, Amalia Avraham, Isaac Beckman, Alon Marx

Patent number: 10296214Abstract: Embodiments for volume management in a data storage environment. A storage pool of a plurality of storage pools is selected to provision at least one storage volume by calculating, for each of the plurality of storage pools, a forecast factor representing an expected usage according to an overall size of the at least one storage volume. The selected storage pool is the storage pool of the plurality of storage pools having a smallest forecast factor.Type: GrantFiled: October 31, 2016Date of Patent: May 21, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ohad Atia, Amalia Avraham, Ran Harel, Alon Marx, Olga Shtivelman

Patent number: 10241869Abstract: When a volume that was once associated with a consistency group and is to be deleted from the storage system, the to be deleted volume is designated as a ghost volume within the storage system, and the deletion of the ghost volume from the storage system is delayed until there are no snapshots that include a pointer to the ghost volume. The storage system may include a counter that counts the number of instances all volumes within a consistency group are pointed to or that counts the number of instances that only ghost volumes are pointed to. The storage system may reference this count to determine whether to immediately delete or delay the deletion of the volume from the storage system.Type: GrantFiled: March 8, 2017Date of Patent: March 26, 2019Assignee: International Business Machines CorporationInventors: Ohad Atia, Amalia Avraham, Ran Harel, Alon Marx

Patent number: 10237340Abstract: A method, including deploying multiple servers as a distributed computing system (DCS) configured to provide a service to clients. At a first time, a given server is configured as an active node in the DCS, the active node configured to and to process requests for the service received from the clients. At the first time, one or more remaining first servers are configured as one or more semi-active nodes in the DCS, each given semi-active node configured to receive, from the clients, requests for the service, and to forward the received requests to the active node for processing. Each of the servers maintains respective counts of the received requests, and at a second time subsequent to the first time, upon identifying a given remaining server having a highest count the given remaining server is reconfigured as the active node, and the given server is reconfigured as a semi-active node.Type: GrantFiled: February 19, 2018Date of Patent: March 19, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ohad Atia, Amalia Avraham, Ran Harel, Alon Marx

Patent number: 10133509Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include identifying a set of storage services on multiple storage systems. A plurality of storage services are defined, each of the storage services comprising a subset of the storage resources, and a defined storage (SDS) system is configured comprising the defined storage services. Multiple sub consistency groups are configured, each of the sub consistency group comprising one or more logical volumes stored in a subset of the defined storage services on a given storage system, and a consistency group is configured comprising the multiple sub consistency groups. Upon detecting a snapshot condition, processing input/output operations to all the volumes in the sub consistency groups can be simultaneously suspended, a snapshot for each of the sub consistency groups is generated, and the processing of the input/output operations is resumed upon generating the respective snapshots.Type: GrantFiled: January 6, 2016Date of Patent: November 20, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ohad Atia, Amalia Avraham, Ran Harel
