Abstract: A source remote copy configuration in a source storage system is migrated to a destination storage system as a destination remote copy configuration. The destination primary storage apparatus of the destination storage system defines a virtual volume mapped to the primary volume provided by the source primary storage apparatus which is a storage area of the virtual volume; takes over a first identifier of the primary volume to the virtual volume; transfers, when the virtual volume receives an access request, the access request to the source primary storage apparatus to write data in the primary volume; and takes over the first identifier from the virtual volume to another primary volume provided by the destination primary storage apparatus, after completion of copy of data from primary volume of the source primary storage apparatus into primary volume of the destination primary storage apparatus and secondary volume of the destination secondary storage apparatus.

Abstract: In a computer system, when a first high availability (HA) pair is configured with a first logical device of a first storage apparatus and a second logical device of a second storage apparatus, the first logical device is virtualized on a third storage apparatus and is set to correspond with a third logical device of the third storage apparatus. A fourth storage apparatus virtualizes the second logical device and sets the second logical device to correspond with a fourth logical device of the fourth storage apparatus. After a second HA pair is configured with the third logical device and the fourth logical device, the data on the first logical device is migrated to the third storage apparatus and managed as data on the third logical device. The data on the second logical device is migrated to the fourth storage apparatus and managed as data on the fourth logical device.

Abstract: A storage management server includes a memory storing management information and a management program and a processor executing the management program with reference to the management information, and manages a storage resource allocated to a server resource. The management information includes group mapping information for converting a first parameter of the server resource into a second parameter of the storage resource in association with the first parameter for specifying the server resource and the second parameter for specifying the storage resource. The processor receives an operation on the server resource and the first parameter and converts the operation on the server resource into an operation on the storage resource based on preset information. The processor converts the first parameter of the server resource into the second parameter of the storage resource with reference to the group mapping information, specifies the storage resource included in the second parameter, and gives an instruction to operate the storage resource.

Abstract: The management computer has a memory which stores management information and management programs, and a CPU which refers to the management information and executes the management programs; the management information includes storage management information for allowing determination as to whether the plurality of storage resources can be paired in a redundant configuration, and couplable configuration management information for determining whether the plurality of storage resources and the plurality of server resources can be connected to each other; and when the CPU deploys a virtual machine, the CPU first determines, by reference to the storage management information, storage resources to be paired in a redundant configuration, then selects, by reference to the couplable configuration management information, server resources each of which can be connected to a respective one of the storage resources that are to be paired in a redundant configuration, and pairs the selected server resources in the redundant configuration.

Abstract: The present invention curbs encryption key information used in a virtual logical volume and improves security. A storage management function 33201 is configured to provide to a host computer a virtual logical volume 327 created on the basis of a pool volume 324. The storage management function is configured to allocate a prescribed page from among pages in the pool volume to a virtual logical volume in accordance with a write request from the host computer. The storage management function is configured to select a page to be allocated to the virtual logical volume on the basis of information regarding encryption key information associated with a page that has been allocated to the virtual logical volume and information regarding encryption key information associated with a page capable of being allocated to the virtual logical volume from the pages managed in the pool.

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.

Abstract: A computer system includes a management computer, a first storage apparatus, and a second storage apparatus. A first logical device of the first storage apparatus and a second logical device of the second storage apparatus constitute a remote copy pair. The second logical device and a third logical device of the second storage apparatus constitute a copy pair. The second logical device and the third logical device have virtual IDs to be recognized by an issuer of an I/O request. The second storage apparatus interchanges the virtual IDs of the third logical device and the second logical device with reception of a command from the management computer as a trigger during processing of the I/O request from the issuer of the I/O request to the third logical device, thereby switching an access destination of the issuer of the I/O request from the third logical device to the second logical device.
