Abstract: Upon data integration for integrating a plurality of pieces of data, each of which has one or more columns, in a column direction, a data integration evaluation system 1 evaluates data integration plans in response to a user's request. The data integration evaluation system 1 includes: a user requirement accepting unit 200 that accepts the data to be integrated and requirements for the data integration; an integration plan evaluation unit 300 that creates integration plans, that is, an integration plan for each column of the data, on the basis of data values of the data and the requirements, which are accepted by the user requirement accepting unit 200, and evaluates the created integration plan; and an evaluation result display unit 400 that outputs a result of the evaluation by the integration plan evaluation unit 300.

Abstract: An inter-switch communication management apparatus for allocating communication bands of inter-switch connections in accordance with priorities is provided. An inter-switch communication management apparatus 200 includes: a virtual network request receiving unit that receives an addition or change of a virtual network as a request with a priority; an inter-switch communication band allocation unit that allocates a communication band to be preferentially used to an inter-switch communication band of a connection between two switches in descending order of the priority of virtual networks; and a switch setting unit that sets the allocated communication band to the connection between the two switches.

Abstract: The display computer displays a management screen having a first area and a second area. In the first area, information related to a computer system, and an input object for a work operation that is a user operation for registering a task of a processing to a computer system into a management computer or an object for displaying the input object are displayed. In the second area, a summary view related to at least one task registered into the management computer is displayed. The summary view has a status object for each status of task, the status object includes an object indicating a status and a value indicating a number of tasks of the status. When the management computer detects a modification of a status of each task that has been registered, the display computer updates a value of a number of tasks in the second area.

Abstract: A primary storage system receives, from a host computer, indivisible data which is a group of data indivisible for maintaining consistency and generated in the host computer by executing an application, stores the received indivisible data, transmits a plurality of journals each including a plurality of data pieces generated by dividing the indivisible data into predetermined sizes, to a secondary storage system, and transmits, to a management computer, journal information representing that each of the plurality of journals has been transmitted.

Abstract: The present invention provides a technique capable of improving use efficiency of storage devices. In this regard, a computer system of the present invention includes: a plurality of storage subsystems; an information processing apparatus coupled to the storage subsystems and including a virtual layer for virtually providing information from the storage subsystems; and the a management system that manages the plurality of storage subsystems and the information processing apparatus. The management system manages, on a memory, configuration information of logical volumes allocated to virtual instances managed on a virtual layer of the information processing apparatus and operation information of hardware resources included in the storage subsystems. The management system evaluates use efficiency of the virtual instances based on the configuration information of the logical volumes and the operation information of the hardware resources and outputs an evaluation result.

Abstract: According to the present invention, it is possible to rearrange an arrangement unit on an appropriate storage device at a more appropriate timing in a complex computer system.

Abstract: A storage management system provides a capability of properly setting a performance monitoring threshold and monitoring a performance of a storage resource in the SAN environment with respect to the operation process being executed. The storage management system includes a management server, a storage device, a storage network, and a management server. The management server is arranged to have a performance information collecting unit for collecting the current performance value of a storage resource, a composition section determining unit for determining a composition section corresponding with a composition ratio of the operation processes, a threshold information storage unit for storing a performance monitoring threshold corresponding with the composition section with respect to one or more storage devices, and a performance determining unit for determining a performance of the storage resource based on the current performance value and the performance monitoring threshold.
