  • Patent number: 10983542
    Abstract: Disclosed is a load-predicting and control system for a subway heating, ventilation and air conditioning system. In one aspect, a load-predicting and control system for a subway heating, ventilation and air conditioning system is provided. The system includes a basic database, a sensing system, a load predicting unit, and a controller; the basic database stores historical data; the sensing system provides measured data; the load predicting unit calculates a predicted load value of the subway heating, ventilation and air conditioning based on the historical data and the measured data, and transmits the predicted load value to the controller; the controller issues a control command based on the predicted load value. Also provided is a load-predicting and control method for the subway heating, ventilation and air conditioning system. The present disclosure solves problems such as poor accuracy of conventional load prediction and inadequate control of the air conditioning system.

  • Patent number: 10955172
    Abstract: Disclosed is a high-temperature air conditioning device. By changing an arrangement mode of throttle valves, a pressure of refrigerant inside a low-pressure pipeline is made to be lower than a pressure of refrigerant inside a medium-pressure pipeline, thus ensuring that the refrigerant, used for cooling components, inside the low-pressure pipeline has a low pressure, thereby solving a problem in the prior art that a frequency converter, a motor and lubricating oil are not cooled sufficiently or cannot be cooled due to excessively high evaporation pressure.

  • Patent number: 10445298
    Abstract: Systems and methods of enabling a service level agreement to specify interactions between an application and a remotely located object store that manages data as objects. A computing device receives data associated with a request to write application data to an object store according to a schedule, wherein the data is file system data. The computing device creates a snapshot associated with the requested application at a snapshot pool, and transmits instructions to a cloud formatting engine to create a virtual disk at a storage pool associated with an object store. The computing device copies the snapshot from the snapshot pool to the virtual disk, the snapshot comprising file system data and transmits instructions to the cloud formatting engine to convert the data associated with the first snapshot into an object, and move the object from the virtual disk to the object store.

  • Patent number: 10379963
    Abstract: Techniques disclosed herein provide for global management of a set of data management services being executed by at least one of one or more physical data management appliances and one or more virtual data management appliances. First instructions are transmitted to a first copy data management appliance that cause the first copy data management appliance to send first data associated with protecting a first application entity to the management server. Second instructions are transmitted to a second copy data management appliance that cause the second copy data management appliance to send second data associated with protecting a second application entity to the management server. A plurality of data management policies associated with the first copy data management appliance and the second copy data management appliance are scheduled using a third service level template, which includes a merged set of schedules for the first and second copy data management appliances.

  • Patent number: 10282201
    Abstract: Systems and methods are provided for automating a provision of applications from a source to a target by providing a virtual copy of application data, wherein the virtual copy can be adapted to a plurality of different target environments. Versions of source application data from an application database at a source production server are maintained at times associated with a schedule. Data associated with a request is received from a user to provision the source application data for a target environment at a target server, the request further comprising application specific parameters that define necessary requirements for the target environment. A virtual copy of the source application data is presented to the target server. Instructions to the target server are transmitted that define how to restore an operational server database from the virtual copy based on the application specific parameters to meet the requirements of the target environment.

  • Patent number: 8954979
    Abstract: Machine implemented method and system is provided for managing resources within an operating environment having a plurality of computing systems and a plurality of virtual machines. The resources are monitored and resource utilization is compared to configured threshold values for managing over utilization. If resource utilization reaches the threshold value, then the resource is identified as being over utilized. One or more data structures are used to display and verify the over utilization on a display device. The root cause of the over utilization is identified and then corrective action may be taken to reduce the over utilization.

  • Patent number: 7600229
    Abstract: Mechanisms and techniques for processing information in a management application, such as a storage area network management application, include a load manager, a set of distributed agents that collect information, and a set of store process that store the agent-collected information. The load manager receives load information from a plurality of store processes. The load information indicates a relative processing load for respective store processes. The load manager determines store process availability based on the received load information. The load manager receives a store assignment request from an agent that has an agent transaction to perform with a store process and assigns a store process of the plurality of store processes for the agent to use to perform the agent transaction based on the determined store process availability.
