  • Patent number: 8266401
    Abstract: Upon receiving a primary/secondary switching command from a secondary host system, a secondary storage control device interrogates a primary storage control device as to whether or not yet to be transferred data that has not been remote copied from the primary storage control device to the secondary storage control device is present. In the event that yet to be transferred data is present, the secondary storage control device receives yet to be transferred data from the primary storage control device and updates a secondary volume. The primary storage control device then manages positions of updates to the primary volume due to host accesses to the primary volume occurring at the time of the secondary storage control device receiving the primary/secondary switching command onwards using a differential bitmap table.

  • Patent number: 8209507
    Abstract: Using a snapshot function, a remote copy is efficiently created. Data for a snapshot is converted into a first bitmap of differential data for a remote copy. The conversion is performed in advance at appropriate chronological intervals. Furthermore, when the snapshot function splits, a second bitmap of cascade differential data, which is new differential data, is created simultaneously with creation of the data for the snapshot. This second bitmap of cascade differential data is created in the same format as the first bitmap of differential data for the remote copy. Then, when the snapshot function shifts from split status to pair status, the second bitmap of cascade differential data is added to the first bitmap of differential data for the remote copy (to produce a logical sum), and a remote copy is created based on this bitmap that was added.

  • Publication number: 20120081332
    Abstract: Provided is a display device equipped with a touch panel, including a front panel arranged above a capacitive touch panel at a predetermined distance away therefrom, in which the touch panel includes a plurality of X electrodes and a plurality of Y electrodes, and the X electrodes are sequentially applied with pulse signals and the Y electrodes receive the pulse signals. When an arbitrary point on the front panel is touched, the touch panel computes a touched point on the touch panel by using both the received pulse signals obtained from the Y electrodes in a case where the front panel is not deformed and the received pulse signals obtained from the Y electrodes in a case where the front panel is deformed. With this, an erroneous operation in which a measurement value is lowered to finally disappear is prevented.

  • Publication number: 20120066466
    Abstract: This storage system supplies, to a plurality of computers, a plurality of duplicate volumes (CVOLs) (corresponding to duplicates of a master volume (MVOL) upon which is stored an electronic object (EO) that is common to the plurality of computers). Both the MVOL and the CVOLS are virtual logical volumes that follow sync provisioning. In the plurality of CVOLs, a plurality of physical regions that are allocated to the MVOL (i.e. regions in which the electronic object is stored) (PAs) are allocated. A storage, when writing an electronic module (EM) to which the EO is applied to the first CVOL, copies data within a first PA that is allocated to the virtual region (VA) that is the write destination to a second PA, writes the EM to the second PA, and moreover allocates the second PA to a VA of the write destination, instead of the first PA. And the storage allocates the second PA to a VA within the second CVOL corresponding to the VA of the write destination, instead of the PA that is allocated to that VA.
