  • Patent number: 8285953
    Abstract: There is a journal area and one or more logical volumes comprising a first logical volume. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any storage area of a plurality of storage areas configuring a logical volume, or a data element that is written to the storage area. A controller has a size receiver that receives a write unit size, which is the size of a write data element received from a computer, and a size setting unit that sets the received write unit size in a memory for one or more logical volumes. The size of a journal data element stored in a journal area based on the set write unit size is the write unit size.

  • Patent number: 8277192
    Abstract: An airfoil profile is formed such that a passage width ratio, represented in a dimensionless manner, of an inter-blade passage width of vane root cross-section to an outlet throat width substantially monotonously decreases from a blade inlet toward a blade outlet. The blade has a blade airfoil profile shape in an envelope within a range of .+?.2.0 mm in a direction normal to any surface location of an airfoil profile portion. The airfoil profile portion has a reference airfoil contour represented in Cartesian coordinates wherein Z is a distance representing a sectional height from a root of the airfoil profile portion. The contours represented by X and Y at each section Z are joined smoothly with one another in a blade height direction to form a complete shape of the airfoil profile portion.

  • Patent number: 8280190
    Abstract: To provide a processing method for reducing motion blur while increasing resolution. By performing a super-resolution process, a resolution-increased image is obtained from an input image in multiple frames. By performing an enlargement process, an enlarged image is obtained from the input image in one frame. A high-frequency image is obtained by subtracting the enlarged image from the resolution-increased image. A high spatial frequency-emphasized image is obtained by adding the high-frequency image to the resolution-increased image. The enlarged image and high spatial frequency-emphasized image are displayed alternately every half frame.

  • Patent number: 8275965
    Abstract: For a storage apparatus in which flash memory disks and hard disks coexist, high-density mounting of flash memory modules is achieved. A storage apparatus in accordance with the present invention includes flash memories and a storage controller. A second storage apparatus including magnetic disks is connected to the storage apparatus. For creation of a logical volume, the storage controller can form a storage area using a flash memory or a magnetic disk. When an input/output request is issued from a host computer, if a storage area is formed with a flash memory, the storage controller directly accesses the flash memory to handle the input/output request. When the storage apparatus defines a storage area formed with a flash memory, the storage apparatus defines the storage area by adding up the capacity of a storage area to be provided for the host computer and a substitute area capacity determined in consideration of restrictions imposed on the number of times of deletion of the flash memory.

  • Patent number: 8275827
    Abstract: Software-based network attached storage (NAS) services are hosted on a massively distributed processing system configured by coupling a multiplicity of distributed devices with a network, wherein each of the distributed devices are enabled to process workloads for the distributed processing system by a client agent program. More particularly, the client agent program is configured with a NAS software component to enable selected distributed devices from the multiplicity of distributed devices to appear to client devices coupled to the network as dedicated NAS devices. The NAS software component allocates an available amount of storage resources in the selected distributed devices to provide NAS services to the client devices. Storage priority controls, including user specified constraints, standard bit, block and file priority levels, and direct bit, block or file priority markings may be utilized to facilitate the full use of the available amounts of unused storage in the selected distributed devices.
