  • Publication number: 20240012959
    Abstract: The number of man-hours is reduced for constructing a digital twin with a digital twin cooperation system that causes a business system related to production including product manufacturing to cooperate with a digital twin for simulating the production based on transaction data and model data. The result data related to the production acquired from the business system is converted into the transaction data using the master data and inputting the transaction data into the digital twin. Included are a change detection step of detecting a change in manufacturing information related to the product manufacturing that the business system has; a determination step of determining whether the change is absorbable in the master data based on an existing record of the master data; and an update step of updating the master data or the model data based on the change according to a determination result of the determination step.

  • Patent number: 9858096
    Abstract: A communication device includes a transfer control unit and a function execution module having a physical processor. The communication device migrates a first process execution unit operated by the function execution module and a management memory to a function execution module of a migration destination. The function execution module notifies the function execution module of the migration destination of information to specify a program allocated to a second process execution unit and information regarding allocation of the physical processor. The function execution module of the migration destination downloads a program file to start the second process execution unit, operates a program of a new second process execution unit by the function execution module of the migration destination, discards the temporary data on the memory of the second process execution unit, and migrates the second process execution unit to the function execution module of the migration destination.

  • Patent number: 7545746
    Abstract: A computer system having a work computer, first storage systems, and second storage systems also has a network, a network routing device, and a management computer. Upon receipt of the update data from the work computer, the first storage system stores the update data in a first storage volume and stores the update data in a second storage volume until the update data is transferred to the second storage system. The management computer obtains an used capacity of the second storage volume of each of the first storage systems and controls the routing of the data by the network routing device based on the obtained used capacity to prevent the cache of each of the storage systems from being overflown.

  • Patent number: 7424590
    Abstract: The present invention proposes a highly reliable storage system and data storage method that can prevent a data copying failure from occurring. If the allocation of a dynamically variable storage area to a primary/secondary logical volume from within that provided by a primary/secondary pool volume results in a storage area shortage in a primary pool volume, the storage system allocates an additional storage area to that primary pool volume from within the storage area provided by a physical volume, and together with this allocation, also allocates an additional storage area to all secondary pool volumes related to that primary pool volume.

  • Patent number: 7398364
    Abstract: In remote data replication between storage systems, there are cases where the storage extent capacity used as the temporary storage extent in the storage system will incur waste. In a system having a management computer, a host computer, a first storage system, and a second storage system, when maintaining the replicated data of the first storage system in the second storage system via remote data replication, a change or the like in the traffic from the host computer to the first storage system is monitored, and the management computer instructs the storage system to switch the remote data replication mode in accordance with such traffic.
