  • Patent number: 9552265
    Abstract: There is provided an information processing apparatus including a control unit. The control unit adds type information indicating a first type in a first operation request in which operation target storage devices are specified by unique identifiers, respectively, used in a first storage apparatus and outputs the first operation request to the first storage apparatus through the network. When the control unit transmits the first operation request to a second storage apparatus and receives an error response indicating a type error from the second storage apparatus after transparent failover is executed, the control unit adds type information indicating the second type in a second operation request in which operation target storage devices are specified by unique identifiers, respectively, used in the second storage apparatus and outputs the second operation request to the second storage apparatus through the network.

  • Publication number: 20110188830
    Abstract: There is provided a high luminous light conductive plate where concave dots formed on the surface of a resin sheet deflect light introduced from a light source to the interior of the light conductive plate so as to diffuse light into an extensive range with a roughened wall surface of the concave dots. An annular projection that flanges the peripheral end portion of each concave dot substantially increases the depth of the concave dots expanding an area contributing to the deflection of the concave dot. The concave dot formed on the surface of the resin sheet is formed by pressing a plurality of concave projections of a press die on the surface of the resin sheet through a cold process.
