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.

An image projection device includes an acquiring unit configured to acquire a first ratio of a second distance to a first distance. The first distance is a distance between a projecting unit that projects a projection image and a first point in a projection area on which the projection image is projected. The second distance is a distance between the projecting unit and a second point in the projection area. The image projection device also includes an estimating unit configured to estimate, using the first ratio, light/dark levels of respective division areas into which the projection area is divided; and a light/dark-level processing unit configured to perform light/dark-level processing on areas in the projection image corresponding respectively to the division areas in accordance with the corresponding light/dark level.

In a distributed file system, when a user requests a computer to create a distributed file, a management computer acquires a list of computers complying with an allocation rule selected by the user from allocation rules taking the performance, security level, reliability level and utility rate into consideration. When the user requests the computer to access the distributed file, on the other hand, the partial files and the server information are collected from each computer. Each computer evaluates the allocation of the partial files based on the selected allocation rule and the server information from each computer, and if required, selects a destination computer and instructs the partial files to be moved to the destination computer.

A NAS (network attached storage) controller managing file system data is configured for use in a storage system having thin provisioning capability. Physical storage capacity is used efficiently by making it possible for the NAS controller to identify to a disk array system having thin provisioning capability which segments of a thin provisioned volume are no longer in use. File system blocks or block groups no longer in use by the NAS controller are identified by the NAS controller. The NAS controller sends a release request to the disk array system specifying thin provisioning segments that correspond to the identified FS blocks or block groups. The release request instructs the disk array system to release chunks of physical storage capacity assigned to the specified thin provisioning segments so that the physical storage capacity can be made available for reuse in the disk array storage system.

An image display system including a plurality of terminals and at least one image display apparatus capable of communicating with the terminals via a network. The image display system includes a first storage part configured to store a connection information list used for connecting to the image display apparatus on the network, an update part configured to add, update, or delete connection information included in the connection information list stored in the first storage part to update the stored connection information list, a searching part configured to search the network for the terminals storing the connection information list, and an acquisition part configured to acquire the connection information list from the terminals detected by the searching part. The update part updates the connection information list stored in the first storage part in accordance with the connection information list acquired by the acquisition part.

A data replication system comprises a NAS controller and a storage system. In a first embodiment, after a NAS system takes a snapshot of a volume, the NAS system changes the referral information within the volume. Also, as an additional way to ensure the consistency after taking a snapshot, the NAS System returns the changed referral information based on a referral management table when clients access a referral within the snapshot volume so that clients can access an appropriate volume. In a second embodiment, after a volume on a NAS system is replicated by remote copy to a remotely deployed NAS system, the remotely deployed NAS system returns the changed referral information based on a referral management table when clients access a referral within the replicated volume so that clients can access an appropriate volume.

An output system is provided that includes at least one output apparatus configured to output content information. The output system includes a determination part configured to determine, based on the content information, whether to generate first control information for switching the output apparatus to a power-saving mode, the first control information being generated with respect to the output apparatus that does not have to output the content information. The output system further includes a control information generation part configured to generate the first control information when the determination part determines that the first control information has to be generated and a power control part configured to switch the output apparatus to the power-saving mode based on the first control information.
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 storage system provides virtual ports, and is able to transfer the virtual ports among physical ports located on multiple storage control units making up the storage system. The storage system is able to manage logical volumes and/or virtual volumes and virtual ports as a group when considering whether to move logical/virtual volumes and/or virtual ports to another storage control unit in the storage system. When the storage system is instructed to transfer volumes, virtual ports, or a group of volumes and virtual ports among the storage control units, the storage system determines whether an inter-unit network will be required to be used following the transfer. When the storage system determines that the inter-unit network will be required if the transfer takes place, the storage system determines and presents an alternate storage control unit for the transfer to avoid use of the inter-unit network, thereby avoiding degraded performance.

A content reproducing apparatus includes a reproducing unit configured to reproduce content including audio and video, and a power control unit configured to perform power control of the reproducing unit based on a reproducing position of the content and non-reproduction period information indicating at least one of a period during which reproduction of the audio of the content is unnecessary and a period during which reproduction of the video of the content is unnecessary.
