A support device and method capable of supporting construction of an optimal secondary usage environment for data are proposed. A plurality of construction candidate plans for a secondary usage environment including a copy method for copying the data between a designated copy source site and a designated copy destination site of the data are calculated. A time and a cost required for copying the data and an operation cost of the secondary usage environment to be constructed are calculated for each of the calculated construction candidate plans, and the plurality of construction candidate plans based on a calculation result together with evaluations thereof are presented.

Support device and method

A data management system for backing up data in a first environment to a second environment includes: backup management information in which source data, backup data, a backup method, and data backed up using the backup method are associated; and a secondary usage data copy unit serving as a secondary usage processing unit that receives a usage request for the backup data stored in the second environment, wherein the secondary usage processing unit refers to the backup management information, specifies the backup data required for processing the usage request, specifies the backup method for the backup data, restores the backup data on the basis of the specified backup method, and enables processing of the usage request.

Data management system and data management method

To quickly and appropriately adjust a performance of a storage system. A storage configuration optimization device for managing a storage system including one or more storages implemented by a plurality of SDS nodes includes a virtual CPU. The virtual CPU is configured to receive a request for an execution period and a necessary performance of a project using the storage system, and select, based on consumption information and performance information of a resource of the storage system, one or more change patterns satisfying the request for the execution period and the necessary performance from among a plurality of change patterns indicating configuration changes of the storage system.

An application executed at a user terminal with a touch screen displays, on the touch screen, a UI in which a user-side UI for accepting a touch operation by a user and a store-side UI for accepting a touch operation by a staff member of a store are placed, as a settlement UI for settlement of a currency amount of a digital local currency. The application judges whether time during which the touch operation on the user-side UI and the touch operation on the store-side UI are simultaneously continued has reached a specified period of time or not. If the judgment result is true, the application displays a settlement completion notice on the touch screen.

Method and system for supporting promotion of use of digital local currency

Example implementations described herein are directed to backup and restore of a public cloud and data center for disaster recovery. In a backup process of the disaster recovery, the VM root device information (a public cloud) and storage system volume information (a data center) in a main site are transferred to the disaster recovery tool. In a restoration process, the DR Tool specifies the storage system volume for backup to attach the VM in a backup site with the above information.

Disaster recovery collaborated with storage system and backup appliance in hybrid cloud environment

Example implementations described herein involve providing an interface configured to receive input to generate a project request for a project; determining an allocation of resources for the project for execution; determining a schedule for the project based on the project request based on the allocation of resources; for the first service platform being available to allocate the resources to execute the project according to the schedule, allocating the resources for executing the project on the first service platform according to the schedule; for the first service platform being unavailable to execute the project according to the schedule, determining whether a second service platform is available to allocate the resources to execute the project according to the schedule, and for the second service platform being available to execute the project according to the schedule, allocating the resources for executing the project on the second service platform according to the schedule.

Efficient management method of storage area in hybrid cloud

Example implementations described herein are directed to management of a first storage system for an on-premise system and a second storage system for a public cloud system. Such example implementations can involve, responsive to an update to one or more of a plurality of snapshot volumes in the first storage system, updating first shared page information stored in the first storage system according to the update to the one or more snapshot volumes, the first shared page information indicative of pages shared between the plurality of snapshot volumes in the first storage system; transmitting instructions to the second storage system to copy the updates to the one or more snapshot volumes from the first shared page information to a second shared page information stored in the second storage system; and executing read or write operations made to the second storage system based on the second shared page information.

A storage system provides a logical volume to a computer, manages the logical volume and a port receiving an I/O request for the logical volume in correspondence with each other, and holds assigned processor management information for managing correspondence between a processor for executing I/O processing based on an I/O request accumulated in a queue and an assigned port being a port corresponding to the queue. The processor identifies an assigned port on the basis of the assigned processor management information, executes I/O processing for the logical volume corresponding to the assigned port, and executes I/O processing on the basis of an I/O request received via the assigned port corresponding to another operation core.

Storage system and method of controlling I/O processing

An integrated circuit device includes first and second integrated circuits and a power supply line. The first integrated circuit includes a first power supply circuit, a timing generation circuit generating a synchronization signal, and a first power supply control section. The second integrated circuit includes a second power supply circuit and a second power supply control section. The power supply line electrically connects the outputs of the first and second power supply circuit. The first and second power supply control sections are each configured to start the operations of the first and second power supply circuits, respectively, in response to a start of a supply of the synchronization signal after a sleep-out command is supplied thereto. The timing generation circuit starts supplying the synchronization signal after a predetermined waiting time elapses after the sleep-out command is supplied to the first integrated circuit.
