Patent number: 10929018Abstract: A mega cluster storage system includes clusters of multiple storage modules. Each module is able to access a portion of the data within the mega cluster and serves as a proxy in order for another storage module to access the remaining portion of the data. A cluster is assigned to a unique cluster volume and all the data within the cluster volume is accessible by all of the modules within the cluster. Each host connection to the mega cluster is associated with a particular cluster volume. A module that receives a host I/O request determines whether the I/O request should be satisfied by a module within its own cluster or be satisfied by a module within a different cluster. The module may forward the I/O request to a module within a different cluster as indicated by a distribution data structure that is allocated and stored within each storage module.Type: GrantFiled: September 20, 2019Date of Patent: February 23, 2021Assignee: International Business Machines CorporationInventors: Zah Barzik, Dan Ben-Yaacov, Mor Griv, Maxim Kalaev, Rivka M.

Patent number: 10831398Abstract: Improving storage device efficiency during data replication. An asynchronous data replication process is initiated between a source computer and a target computer over a network. Performance of the target computer and a storage device of the target computer is monitored. At least one portion of data stored on the source computer is identified for the data replication, wherein the at least one portion of the data is organized in a data block. Whether to modify a size of the data block is determined, based on the monitored performance of the target computer. Responsive to determining to modify the size of the data block, based on the monitored performance of the target computer, the size of the data block is modified.Type: GrantFiled: September 19, 2016Date of Patent: November 10, 2020Assignee: International Business Machines CorporationInventors: Zah Barzik, Lior Chen, Maxim Kalaev, Deborah A.

Patent number: 10776018Abstract: Embodiments for discovering read failures in a data storage system. Data read from underlying media of the data storage system is validated by initializing a prefix of a buffer used to read the data with a first sequence of bytes of a predefined number. The first sequence of bytes is compared to a sequence of actual bytes of the data read into the buffer. When the first sequence of bytes returns an equal value to the sequence of the actual bytes of the data read, a second sequence of bytes of the predefined number is generated and compared to a subsequent data read to determine the validity.Type: GrantFiled: June 19, 2017Date of Patent: September 15, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Zah Barzik, Yair Elharrar, Maxim Kalaev, Deborah A.

Patent number: 10637921Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include initializing multiple computing nodes to execute one or more software applications that provide a computing service, each of the computing nodes having a respective set of configuration data. Examples of the services include storage services, computational services and web service. Subsequent to deploying the multiple computing nodes as a software defined computing (SDC) cluster, an additional computing node is initialized using a given set of configuration data, and the additional computing node is added to the SDC cluster. In some embodiments, the additional node can be initialized and added to the SDC cluster in response to detecting a condition in the SDC cluster. In alternative embodiments, the additional node can be initialized and added to the SDC cluster in response to receiving a request to add an additional service to the SDC cluster.Type: GrantFiled: April 24, 2018Date of Patent: April 28, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Zah Barzik, Maxim Kalaev, Eli Koren, Amit Margalit, Eran Tzabari

Patent number: 10469288Abstract: Embodiments for network management in a Software-defined Storage (SDS) environment. Remote mirroring connectivity and data transfer is optimized in the SDS environment by establishing each of a plurality of nodes in a local storage array and a remote storage array as a gateway node. Data residing on a local gateway node is transferred directly to a remote gateway node owning the data, thereby avoiding interconnect data hops and improving datacenter network utilization.Type: GrantFiled: November 1, 2016Date of Patent: November 5, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Zah Barzik, Lior Chen, Demian Glait, Maxim Kalaev, Rivka M.

Publication number: 20190294346Abstract: A data handling system includes multiple storage devices that each have a limited number of write and erase iterations. In one scheme, a deterministic endurance delta is created between a storage device (benchmark storage device), and the other storage devices so that the benchmark storage device has less endurance than the other storage devices. The benchmark storage device will likely reach endurance failure prior to the other storage devices and the probability of non-simultaneous endurance failure increases. In another scheme, a deterministic endurance delta is created between each of the storage devices so that each of the storage devices have a different endurance level than the other storage devices. By implementing the endurance delta simultaneous endurance failures of the storage devices may be avoided.Type: ApplicationFiled: March 26, 2018Publication date: September 26, 2019Inventors: Zah Barzik, Ramy Buechler, Maxim Kalaev, Michael Keller, Amit Margalit, Rivka Matosevich

Patent number: 10257066Abstract: Methods, systems, and computer program product embodiments for controlling congestion in a storage grid, by a processor device, are provided. In a storage grid, a storage request transmit queue length of storage requests submitted by a plurality of nodes is monitored, the storage request transmit queue comprising a queue holding the storage requests unable to be transmitted through a current transmission control protocol/internet protocol (TCP/IP) socket buffer of the storage grid. Upon reaching at least one of a certain threshold, a watermarked message indicating a specific one of the plurality of nodes is congested is transmitted to upper layer grid nodes in a hierarchy of the plurality of nodes transmitting the storage requests, and the upper layer grid nodes each alter the storage requests based upon the watermarked message.Type: GrantFiled: November 7, 2017Date of Patent: April 9, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jonathan Amit, Zah Barzik, Vladislav Drouker, Maxim Kalaev

Patent number: 10031823Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include defining, for a computer system, one or more system tests, and performing each of the system tests on the computer system. Each of the system tests includes one or more system commands, and in some embodiments, a given system test may be performed by executing one or more system commands while the computer system simultaneously processes additional system commands that perform input/output operations. Upon detecting a failure of a given system command in a given system test to execute correctly, the computer system can be configured to suppress execution of the given system command. In some embodiments, the computer system includes a hypervisor controlling a virtual machine configured as a node of a software defined storage system, and the failure can be a disruption of the hypervisor or the virtual machine.Type: GrantFiled: March 21, 2016Date of Patent: July 24, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Zah Barzik, Lior Chen, Maxim Kalaev
