  • Publication number: 20080270696
    Abstract: The present invention is a management computer that determines, as the assignment source of a logical volume that is assigned in order to store predetermined data, a storage area of a RAID group including one or more disk drives among a plurality of disk drives provided in a storage system; and the CPU that executes the volume assignment module accepts a logical volume assignment request and, in cases where a logical volume assignment request is accepted, determines the RAID group which is the assignment source of the logical volume on the basis of the access trend assumed for the logical volume which is the subject of the assignment request.

  • Patent number: 7415573
    Abstract: The storage system of the present invention comprises a plurality of physical storage regions comprising a physical storage region having one or more attributes, and a physical storage region having a plurality of attributes. A prescribed attribute is allocated for each pool constituted from two or more physical storage regions, and each such pool has overlapping physical storage regions, which overlap one another, and non-overlapping physical storage regions, which do not overlap one another. The overlapping physical storage region constitutes two or more pools of the plurality of pools because it has the same plurality of attributes as the plurality of attributes respectively allocated to the plurality of pools, but the non-overlapping physical storage region is not like this, and constitutes only one pool.

  • Patent number: 7409255
    Abstract: A module evaluation method and system which can quickly determine overall effectiveness of the modular construction method in an automatic manner, taking into account the transportation cost and so on. A module evaluation unit prepares constructed-equipment physical quantity data from constructed-equipment layout data, and determines an in-module unit-rate reduction effect resulted from executing construction work of the constructed equipment in the module in a factory where working efficiency is higher than a field. The module evaluation unit also determines a module transportation cost effect, a module temporary construction cost effect, and a density reduction effect that is resulted from a reduction of density in a space not occupied by a module with application of modularization and efficiency of installation work is increased.

  • Publication number: 20080086612
    Abstract: Provided is an access right managing method for a resource of a storage system, in which a management computer stores access right definition information of the resource, and resource correspondence information including information on a management program which manages another resource related to the resource managed by the management program. In case of which receiving an updating request of an access right of the resource, the management computer updates an access right based on the updating request of the access right, selects a management program of the resource whose access right is requested to be updated based on the resource correspondence information, transmits an updating request of an access right for a relative resource to a management computer which executes the selected management program, and in case of which the access right updating request of the related resource is received, updates the access right of the relative resource.

  • Publication number: 20070205870
    Abstract: To support a tag information reader to read information from radio communication tags, attached to each of a plurality of structural objects in a plant and to provide the locations of unread radio communication tags, a tag information acquisition unit acquires information on radio communication tags actually read by the tag information reader. Next, an unread tag extraction unit extracts radio communication tags which are a plurality of radio communication tags stored in a tag arrangement data file but from which information cannot be acquired by the tag information acquisition unit, and an unread tag arrangement calculation unit acquires arrangement data on the extracted radio communication tags. The arrangement data on those radio communication tags is sent to a display unit for displaying the radio communication tags.

  • Publication number: 20060101399
    Abstract: A CPU 11 executes a management program B (Pb), from a management program A (Pa) receives authentication information, a request, and a program ID, and determines whether the authentication information is correct. If the authentication information is correct, the CPU 11 acquires the execution authority information of the authenticated user, compares the received program ID with the program ID including in the acquired execution authority information, and determines whether execution authority corresponding to the received program ID is defined. If the CPU 11 determines that execution authority corresponding to the received program ID is defined, it established the defined execution authority as the execution authority for the management program B (Pb).

  • Patent number: 6924327
    Abstract: An ink set, exhibiting good ink permeability and fixation, capable of yielding high quality images with no roughness, or an ink set capable of yielding text and/or images of outstanding light resistance, is provided. The ink set of the present invention comprises a dark ink composition and a light ink composition that, while being mutually the same color, are of different color density, and is characterized in that the dark ink composition and the light ink composition each comprise a pigment as a colorant and a resin as a dispersant, in that the ratio between the resin weight proportion B1 and the pigment weight proportion P1 in the dark ink composition (i.e. B1/P1) is lower than the ratio between the resin weight proportion B2 and the pigment weight proportion P2 in the light ink composition (i.e. B2/P2), and in that B1 and B2 differ from each other.
