  • Patent number: 8037245
    Abstract: One code (a compressed redundant code) is created based on a plurality of first redundant codes, each created on the basis of a plurality of data units, and this compressed redundant code is written to a nonvolatile storage area. This compressed redundant code is used to restore either a data element constituting a multiple-failure data, or a first redundant code corresponding to the multiple-failure data, which is stored in an unreadable sub-storage area of a partially failed storage device, and to restore the data element constituting the multiple-failure data which is stored in a sub-storage area of a completely failed storage device, based on the restored either data element or first redundant code, and either another data element constituting the multiple-failure data or the first redundant code corresponding to the multiple-failure data.

  • Patent number: 7985663
    Abstract: A resin layer made of thermoplastic resin is formed on a supporting substrate, and then, an insulating layer is formed on the first resin layer. Then, an interlayer connector is formed through the insulating layer and then, a wiring layer is formed on the first resin layer so as to be electrically connected with the interlayer connector. Thereafter, a first semiconductor chip is mounted on the wiring layer. Then, the first resin layer is heated so that the supporting substrate and the insulating layer are relatively shifted one another to shear the first resin layer, thereby separating the supporting substrate and the insulating layer and forming a semiconductor device.

  • Publication number: 20110126058
    Abstract: This storage controller includes a port unit and multiple processing units for inputting and outputting data to and from a storage apparatus. The port unit sorts the data I/O requests given from a host system to the corresponding processing units according to a table pre-defining the storage apparatus or a storage area in the storage apparatus to perform data I/O processing allocated to each of the processing units. The processing unit inputs data in the corresponding storage apparatus or the corresponding storage area according to the data I/O request sorted to itself from the port unit and, upon detecting a blockage of the other processing unit due to a failure, updates the table retained in each of the port units so as to sort the storage apparatuses or the storage areas allocated to the other processing unit to the remaining unblocked processing units.

  • Publication number: 20110056317
    Abstract: In a twin-clutch transmission, when a third shift valve (for example) goes out of order and the shift change accordingly becomes incapable of being carried out, the hydraulic pressure outputted from the third shift valve is controlled by a fourth shift valve operated by a first shift solenoid for a first shift valve. Accordingly, the hydraulic pressure outputted by a second linear solenoid is supplied to one of second hydraulic actuators, thereby enabling one of second predetermined transmission gear stages to be pre-shifted by use of a second power transmission path. When the first shift valve is used as a fail-safe, it is possible for the vehicle to make a minimum necessary run by setting up one of the second predetermined transmission gear stages. Furthermore, the fourth shift valve is driven by use of the existing first shift solenoid, thus minimizing the number of parts and cost.

  • Publication number: 20100199038
    Abstract: In a configuration in which it is necessary to transfer data from a first storage system to a third storage system through a storage system between the storage systems, there is a problem that it is inevitable to give an excess logical volume to a second storage system between the storage systems. A remote copy system includes first storage system that sends and receives data to and from an information processing apparatus, a second storage system, and a third storage system. The second storage system virtually has a second storage area in which the data should be written and has a third storage area in which the data written in the second storage area and update information concerning the data are written. Data sent from the first storage system is not written in the second storage area but is written in the third storage area as data and update information. The data and the update information written in the third storage area are read out from the third storage system.

  • Patent number: 7725445
    Abstract: A first storage system stores information relating to the updating of data stored in that system as a journal. More specifically, the journal is composed of a copy of data that was used for updating and update information such as a write command used during updating. Furthermore, the second storage system acquires the journal via a communication line between the first storage system and the second storage system. The second storage system holds a duplicate of the data held by the first storage system and updates the data corresponding to the data of the first storage system in the data update order of the first storage system by using the journal.
