    摘要: Backup and restore operations are made possible in a storage system that has dynamic chunk allocation (DCA) capability. In a DCA storage system, a chunk of physical storage area is not allocated to a segment of a volume until a write command is received targeting the segment of the volume. During a restore operation of the volume in the DCA storage system, the wasting of storage capacity when a backup image of the volume is restored is mitigated by preventing allocation of physical storage areas to segments of restore data that are only void data.

    摘要: A storage system is configured to create and manage virtual ports on physical ports. The storage system can transfer associations between virtual ports and physical ports when a failure occurs in a physical port or a link connected to the physical port so that a host can access volumes under the virtual ports through another physical port. The storage system can also change associations between virtual ports and physical ports by taking into account the relative loads on the physical ports. When a virtual machine is migrated from one host computer to another, the loads on the physical ports in the storage system can be used to determine whether load balancing should take place. Additionally, the storage system can transfer virtual ports to a remote storage system that will take over the virtual ports, so that a virtual machine can be migrated to remote location.

    摘要: An image processing apparatus includes an image separating unit that separates and creates a plurality of derivative images from an input image based on feature of the input image; a coding unit that codes each of the derivative images separately, couples coded data of the derivative images, and generates multilayer structure data; and a controller that controls a code amount of coded data of at least one derivative image with a low code assignment priority out of the derivative images so that a data amount of the multilayer structure data is equal to or less than a limit amount.

    摘要: Data of a global file system spread over multiple local NAS systems may be consolidated as a copy into a single remote NAS system. When remote copy is set up, the local NAS systems replace referrals within the global file system with directories and send these in place of the referrals to the remote NAS system. Then, other local NAS systems referred to by the referrals send files and directories under the directories replacing the referrals on the remote NAS system. Alternatively, to split copy data of a locally-stored global file system amongst multiple remote NAS systems, the local NAS system replaces specified directories with referrals, and sends the referrals with the data to one of the remote NAS systems. Then, the local NAS system sends files and directories under the directories replaced with referrals to one or more other remote NAS systems as referred to by the referrals.

    摘要: A system renting out file servers to many companies in a data center has a security problem so that the user cannot perform operation needing manager authorization in the file servers. An OS provides execution administrative area information of an application program designated by process information which can specify the range of an accessible device to operate the server system of the customer in the administrative area information.

    摘要: In an image processing apparatus, an encoding unit encodes a processed image; a determining unit determines whether a reference pixel has been subjected to the image processing; and a decoding unit decodes, when the determining unit determines that the reference pixel has been subjected to the image processing, a piece of rectangular block code data of a rectangular block thereby acquiring a second decoded image. The encoding unit refers to, when the determining unit determines that the reference pixel has been subjected to the image processing, the processed image and encodes the second decoded image.
