  • Publication number: 20220301034
    Abstract: Regarding MS information, information about each of a plurality of MS's includes meta information of the relevant MS. Regarding model information, information about each of one or a plurality of models includes meta information of the relevant model. A system evaluates appropriateness of an evaluation destination MS/model for an evaluation source MS/model as a replacement MS/model for the evaluation source MS/model on the basis of the meta information of the evaluation destination MS/model and the meta information of the evaluation source MS/model. The system recommends one or more evaluation destination MS's/models, as a candidate for a replacement MS/model of a designated MS/model, to a user on the basis of evaluation of each of one or two or more evaluation destination MS's/models regarding which the MS/model designated by the user in an application configured from one or two or more MS's/models is the evaluation source MS/model.

  • Patent number: 11327724
    Abstract: When flow data of flow is to be downloaded from a flow template manager to a flow editor, a system receives a first request to deploy an external service corresponding to an invoke node in the flow, and transmits a second request to deploy an external service identified by the first request to a service deployment manager associated with a site corresponding to the external service. The service deployment manager deploys an external service identified by the second request on a service execution platform at the site, and returns a response associated with an invocation destination end point corresponding to the external service. The system returns a first response associated with an invocation destination end point set to a property of the invoke node by the flow template manager to a transmission source of the first request.

  • Patent number: 11209889
    Abstract: Status information including remaining battery power is collected from a management target device. Subsequent operations of the device are identified from an operation schedule management collection. Battery consumptions corresponding to subsequent operations of the device are estimated from KPI management collection that includes information representing relationships between battery consumptions and operations with respect to each of a plurality of devices. The battery life of the device is predicted based on the estimated battery consumptions and the remaining battery power represented by the collected status information. A circuit schedule of a maintenance engineer is determined based on the predicted battery life, the schedule including necessity of dispatch of the maintenance engineer to the device.

  • Patent number: 11196806
    Abstract: Example implementations described herein are directed to replication of data between different environments selectively while maintaining the performance of applications. The replication of data may be used to replicate data from a data center running a business critical application to another data center running an analytics application. In example implementations, a storage management program translates the IDs of database tables to storage locations, and the storage management program requests a storage system to replicate those storage locations to another storage system.

  • Patent number: 10983882
    Abstract: Example implementations described herein are directed to systems and methods involving an application running on a host computer and configured to manage storage infrastructure. The application not only manages resources already allocated to itself, but also manages the allocation and de-allocation of resources to itself. The resources can be allocated and de-allocated based on the type of process being executed, wherein upon occurrence of a failure on a primary storage system, higher priority processes that are executed on connected failover storage system nodes are given priority while the lower priority processes of such failover storage system nodes are disabled.
