Abstract: A management includes an acquiring unit for acquiring information of specifying a target virtual storage in a target storage pool and an expansion storage capacity to be acquired from another storage pool other than the target storage pool, and a determining unit for determining the real storage to be used for the expansion storage capacity of the target virtual storage from candidate one of the real storages in the another storage pool, which are under the control of the controller in charge of the real storage that the target virtual storage is defined, on the basis of an occupied storage capacity defined as the virtual storage on the real storage in the another storage pool and a free storage capacity of the real storage in the another storage pool.

Abstract: When information on a device such as a server, storage, and an FC switch constituting a SNA system is input, these devices are displayed and arranged properly on a screen (S1, S2). When information on a physical path is input by a designer by using this display screen, a virtual SAN system in which the devices are connected by a fiber channel is displayed on the screen (S3). Furthermore, when information on an access path is input by the designer by using the construction image, the access path is additionally displayed on the construction image of the virtual SAN system (S5). Since the construction image of the virtual SAN system is displayed on the screen, the designer can easily create a design drawing while visually checking the SAN system. This can reduce the work load and time required for construction of the SAN system.

Abstract: A computer program, method, and apparatus that can easily perform setting taken into account the reliability of and the load on a disk array. A logical volume requirement acquisition section acquires a logical volume requirement. An applied technique determination section then determines an applied technique for improving at least one of reliability and processing speed according to the logical volume requirement. A logical volume setting section then outputs instructions to generate a logical volume which is made up of a plurality of disk drives and which is used for realizing the determined applied technique and instructions to set an environment in which a server accesses the logical volume by using the applied technique to the server and a disk array.

Abstract: A reliability verification program that enables network administrators to verify the redundancy of a system that they operate. With reference to network configuration data describing physical connections of a network system, the program selects a source device and a destination device as a start point and an end point of access routes. A verification route is then determined by tracing the physical connections from the selected source device to the selected destination device. Based on the network configuration data, the program creates network configuration verification data by excluding data about devices and physical links involved in the determined verification route. This network configuration verification data is used to find a redundant route from the source device to the destination device. The presence of a redundant route corresponding to the verification route means that the network system has good redundancy in its physical connections.

Abstract: A virtual storage architecture management system for producing a virtual storage architecture on the basis of information on a storage device comprises a storage device having a plurality of storage areas, information processing equipment that performs various kinds of information processing on the storage device, and a selective linkage unit that establishes a plurality of paths between the information processing equipment and the plurality of storage areas in the storage device. The information processing equipment includes a control unit that retrieves information on the real configuration of the storage device and information on the paths from an information preserver, and calculates information on all paths required for a virtual storage architecture. Also disclosed is a method for producing a virtual storage architecture using the virtual storage architecture management system, or the like, according to the present invention.

Abstract: The present invention relates to a library apparatus for accommodating different types of recording medium, such as magnetic tapes, in combination. By a method for reading markers, in which the type of the recording medium and its volume label are recorded, by moving a reader, and a construction for sorting and accommodating the different types of recording medium, the markers can be read at a high speed.

Abstract: An apparatus for assisting the realization of a storage area network (SAN) system is provided. The assisting apparatus includes first and second information input means and plan generating means. The first information input means is provided for inputting device data of the servers, the storages and the fiber channel switches used for the SAN system. The second information input means is provided for inputting information about physical connection among the servers, the storages and the switches. The plan generating means is provided for generating, based on the information inputted through the two information input means, a plan of a virtual storage area network system. The generated plan is visually presented by a display.

Abstract: A library unit including a plurality of frames and a plurality of cell shelves, each of the cell shelves having a plurality of cells arranged in an X-Y plane. The plurality of cell shelves are located in at least one of the plurality of frames, at least one accessor having a picker portion, and a plurality of first reference flags, each of which having substantially the same X-axis coordinate are provided with each of the frames with a spacing in the Y-axis direction. According to the library unit, the plurality of first reference flags are detected by a sensor attached to the picker portion, and a relative inclination angle of the accessor with respect to the Y axis in the X-Y plane is calculated from a difference in position in the X-axis direction of plurality of reference flags in order to obtain a correction value in the X-axis direction for each cell.

Abstract: The present invention provides a cartridge carrying system for performing carriage control so as to enable carriage of a cartridge even when a gap is made between arms and the cartridge.
