  • Publication number: 20110314325
    Abstract: A storage apparatus has a physical storage area used by an external apparatus, a drive interface unit, a power supply unit, and a storage controller executing data write processing from the external apparatus to the storage drive and data read processing from the storage drive through the drive interface unit, and a drive control interface unit. The power supply unit inputs power supply information to the drive interface unit. Any one of the processing units acquires the power supply information of the power supply unit through a data network path to the drive interface unit for the data write processing and the data read processing, and determines whether or not a failure occurs in the power supply unit supplying the operation power to the storage drive and the drive interface unit, on the basis of the acquired power supply information.

  • Patent number: 7925930
    Abstract: A storage control system of the present invention can carry out settings for a storage device using redundantly configured access channels. A controller of the storage control system can access a storage device using a plurality of access channels of system A and system B. Respective I/F control units each comprise a plurality of normally open-type switches. The switches of system A and the switches of system B are respectively wired-OR connected. A disk control unit outputs a control signal to an I/F control unit on the basis of a setting table. When a failure occurs in an I/F control unit of system A, the output signals of the respective switches transfer to a high-impedance state. Therefore, a storage device can be set by outputting, from an I/F control unit of system B, a signal corresponding to a desired operational mode and identification information.

  • Publication number: 20100240480
    Abstract: The present invention provides an anti-rotation structure for a balance chamber snap ring of a belt type continuously variable transmission having a balance chamber that balances a centrifugal oil pressure generated in an oil pressure chamber formed on a movable sheave back surface. A projecting portion, which comes into contact with an end portion of the balance chamber snap ring when the balance chamber snap ring rotates independently within a ring groove about a secondary shaft, thereby restricting independent rotation of the balance chamber snap ring, is provided on a latch portion of a cover member. As a result, independent rotation of the balance chamber snap ring can be prevented, thereby preventing the cover member and the balance chamber snap ring from becoming worn.
