  • Patent number: 9632701
    Abstract: A storage system includes a first storage apparatus including a first logical volume and a second storage apparatus including a second logical volume. The first and second logical volumes are set as a High Availability pair and associated with a virtual volume. When receiving a write request to the virtual volume, the storage system manages storage area in the first logical volume regarding to the write request as storage area during data duplication, writes data in duplicate, in order from the first logical volume to the second logical volume. When receiving a read request to the virtual volume, the first storage apparatus waits for completion of the data duplication and reads data from the first logical volume if the storage area is during the data duplication, and the first storage apparatus reads data from the first logical volume if the storage area is not during the data duplication.

  • Publication number: 20170017403
    Abstract: A storage system creates an HA configuration in a virtual storage composed of resources of first and second storage subsystems. A user of the virtual storage selects a replication destination volume (second logical volume) of a first logical volume of the first storage subsystem that the user wishes to duplicate from the second storage. At this time, only a logical volume not recognized from a host is selectable as the second logical volume. When data duplication between the first logical volume and the second logical volume is started, the second storage subsystem sets an identification number of the second logical volume to be the same as the identification number of the first logical volume. Thereafter, at the point of time when duplication is completed, the second storage changes the setting of the second logical volume so that the second logical volume can be recognized from the host.

  • Publication number: 20160131474
    Abstract: A non-contact surface-shape measuring method uses a white light interferometer optical head that divides, through a beam splitter, light emitted from a white light source into reference light for a reference mirror and measurement light for a measured object surface; obtains an image having interference fringes generated from an optical path difference of light reflecting from the reference mirror and light reflecting from the measured object surface; and is displaced for scanning in a vertical direction with respect to the measured object surface in order to obtain the image having interference fringes. While the white light interferometer optical head is displaced in a scanning direction, a position of the optical head in the scanning direction is detected, and the image having interference fringes is obtained at predetermined spatial intervals in the scanning direction.
