  • Patent number: 10769006
    Abstract: A management entity receives device fingerprints representing corresponding devices connected to one or more networks. Each device fingerprint includes a multi-bit word indicating hardware, software, network configuration, and failure features for a corresponding one of the devices. The management entity processes the device fingerprints using different methods including statistical risk of failure scoring methods and machine learning risk of failure scoring methods, to produce from each of the methods a respective risk of failure for each device. The management entity combines the respective risk of failures for each device into a composite risk of failure for each device, ranks the devices based on the composite risk of failures for the devices, to produce a risk ranking of the devices, and outputs the risk ranking.

  • Patent number: 10769007
    Abstract: A system may include a node historical state data store having historical node state data, including a metric that represents a health status or an attribute of a node during a period of time prior to a node failure. A node failure prediction algorithm creation platform may generate a machine learning trained node failure prediction algorithm. An active node data store may contain information about computing nodes in a cloud computing environment, including, for each node, a metric that represents a health status or an attribute of that node over time. A virtual machine assignment platform may then execute the node failure prediction algorithm to calculate a node failure probability score for each computing node based on the information in the active node data store. As a result, a virtual machine may be assigned to a selected computing node based at least in part on node failure probability scores.

  • Patent number: 10754763
    Abstract: Systems, methods, and computer-readable media are disclosed for generating a test case based on valid function codes that have not been selected for test case generation bypassing. A test program is provided that allows a user to specify, for each instruction, one or more function codes that the user does not want to use to generate a test case (e.g., that should be bypassed). A test stream generator is provided that has knowledge of valid and invalid function codes for any given supported instruction. A test case generator is provided that compares the function codes selected for bypassing to the valid function codes to identify a valid non-bypassed function code, which is used to generate a test case. Systems, methods, and computer-readable media are also disclosed for generating an exception test case using only one or more invalid function codes that have not been selected for bypassing.

  • Patent number: 10754741
    Abstract: A migration system or service may implement event-driven replication for migrating a computing resource from a source network to a destination network. A replication event may be detected to obtain a state of a data volume for a computing resource hosted in a client network. A request to a replication agent hosted in the source network may instruct the replication agent to copy at least some of the data of the data volume and send the data to the destination network. The migration service may generate a state of the data volume from the received data in a format that is operable to host the computing resource in the destination network and store the generated state of the data volume.

  • Patent number: 10747632
    Abstract: This disclosure describes techniques for monitoring network node traffic and dynamically re-directing network node traffic from an active repository that has a non-operational data cluster, to a standby repository with an operational alternate data cluster. Particularly, a “Data Redundancy Allocation” (DRA) system is described that can monitor the operational integrity of an active repository and dynamically co-ordinate and re-direct network node traffic to a standby, redundant data repository in response to detecting that the active repository is no longer operational. In doing so, the data redundancy allocation system may ensure a continuous communication stream of data traffic from network nodes to data repositories (i.e., active repository or a designated standby repository) in spite of a data repository inadvertently becoming non-operational, or intentionally brought offline for a planned upgrade.

  • Patent number: 10747630
    Abstract: An illustrative “VM heartbeat monitoring network” of heartbeat monitor nodes monitors target VMs in a data storage management system. Accordingly, target VMs are distributed and re-distributed among illustrative worker monitor nodes according to preferences in an illustrative VM distribution logic. Worker heartbeat monitor nodes use an illustrative ping monitoring logic to transmit special-purpose heartbeat packets to respective target VMs and to track ping responses. If a target VM is ultimately confirmed failed by its worker monitor node, an illustrative master monitor node triggers an enhanced storage manager to initiate failover for the failed VM. The enhanced storage manager communicates with the heartbeat monitor nodes and also manages VM failovers and other storage management operations in the system. Special features for cloud-to-cloud failover scenarios enable a VM in a first region of a public cloud to fail over to a second region.

  • Patent number: 10747651
    Abstract: A system for optimizing system resources and runtime during a testing procedure is disclosed. During operation, the system may perform hypothesis testing on an application under evaluation, such as performing hypothesis testing on suggested constraints for the application under evaluation, which may result in the creation of new hypotheses yielding improved confidences. This testing may be optimized by simplifying and/or reducing the number of hypothesis tests used during the testing process. To do so, the hypothesis tests may be sorted into sets, and a subset of these sorted hypothesis tests may be executed. Based on the results of this testing, a remaining portion of the hypothesis tests may be skipped, allowing for an optimization of the testing process without reducing the quality of the testing procedure.

  • Patent number: 10725842
    Abstract: Methods, systems, apparatus, and non-transitory computer readable media are described for detecting system outages using application event logs. Various aspects may include obtaining several prior application event logs where the status of the system is known at the time the application event logs were recorded. Additionally, various aspects may include determining characteristics of prior application event logs which were recorded during a system outage, and/or determining characteristics of prior application event logs which were recorded while the system was available. When current application event logs are obtained where the status of the system is unknown at the time the current application event logs are recorded, various aspects include comparing the current application event logs to the prior application event logs to determine that a system outage has occurred based upon the comparison.
