At the time of migrating encrypted data into another storage apparatus, it is made easy to decrypt this data after migration, the security against tapping, falsification and the like is maintained when a calculation method of encrypted data is re-written into another calculation method, and also access performance is improved. In a storage system 100 which is provided with a storage apparatus having a volume 120 and which is accessible from a host computer, it is made possible to execute the data migration when a storage apparatus provided with a mechanism capable of decrypting the encrypted data is chosen as a migration destination of this data, and also to keep holding surely the encrypted data by updating and saving again a encryption method applied to a encryption of the encrypted data into another method by internal processing of the apparatus even when the apparatus and the encryption method become obsolete.

A caching storage method and system that includes one or more host devices, network devices, storage devices, and logical volume management functions. An input/output (I/O) request is received from the host device that includes a logical block address. The logical block address is translated into an original storage address for a storage device that includes an original storage ID, storage unit ID and block address. It is determined if a cache is defined for the storage device. The original storage address is translated into an address for a cache associated with the storage device if the cache is defined for the storage device. A read request or a write request is sent to the cache address based on the I/O request. Block data is received or transferred from/to the cache defined for the storage device identified by the original storage ID and storage unit ID.

A storage service manager facilitates an operator's task for managing large-scale storage facilities. Allocating access paths on the storage network is accomplished by the use agent programs which interface to various components comprising a data path from the client to the storage system. The agent programs hide various vendor-specific and technology-dependent aspects of the storage network components from the user.

Poses of a movable camera relative to an environment are obtained by determining point correspondences from a set of initial images and then applying 2-point motion estimation to the point correspondences to determine a set of initial poses of the camera. A point cloud is generated from the set of initial poses and the point correspondences. Then, for each next image, the point correspondences and corresponding poses are determined, while updating the point cloud.

A resonance-type non-contact power supply system is configured such that a power supply section is changeable in output frequency, and has an impedance measuring section that measures the input impedance of a resonant system. The power supply system includes a control section that performs control for transmitting proper power to power receiving equipment after changing the output frequency (fo) of the power supply section to lie within one of the frequency ranges f1≦fo≦f2, . . . , f2n-1≦fo≦f2n. The frequencies f1, f2, . . . , f2n-1, f2n (f1
摘要:
A visual hull for a 3D object is generated by using a set of silhouettes extracted from a set of images. First, a set of convex polyhedra is generated as a coarse 3D model of the object. Then for each image, the convex polyhedra are refined by projecting them to the image and determining the intersections with the silhouette in the image. The visual hull of the object is represented as union of the convex polyhedra.

A system is described in which a plurality of host computers are coupled to a storage system for storing and retrieving data in the storage system. The storage system includes individually addressable units of storage such as volumes or logical unit numbers. A security management system controls access to each of the individually addressable units of storage based upon the identification of the host permitted to access that unit of storage.

An oil-pressure apparatus is provided with an actuating cylinder that works on the outside and an acceleration cylinder that does not work on the outside. When a rod of the actuating cylinder is extended with no load applied to the actuating cylinder, oil is supplied to the actuating cylinder through the acceleration cylinder so that extension of the rod is accelerated. When the rod of the actuating cylinder is extended with load applied to the actuating cylinder, oil is adjusted to the actuating cylinder without passing through the acceleration cylinder so that original thrust of the actuating cylinder is exerted.
摘要:
A storage system including a first storage apparatus having at least one volume to be provided to a host computer, a second storage apparatus connected to the first storage apparatus and having a second volume having a pair relationship with a first volume, and a management apparatus. The management apparatus includes a user interface for setting an attribute of functions related to at least one volume of the first storage apparatus and at least one volume of the second storage apparatus. The management apparatus compares an attribute of a first function related to the first volume and an attribute of a second function related to the second volume, and sets the attribute of the second function to be consistent with the attribute of the first function. The management apparatus there commands restoration of the first volume or the second volume to a state before the set the attribute operation.
摘要:
A data migrating method including calculating, in a case where data stored in a volume is migrated to another volume, a required period of time for migrating the data based on a size of data to be migrated and volume configuration information on the volume in which the migrated data is stored and the volume to which the data is to be migrated, determining a start time at which the data migration starts to generate a volume migration plan, setting a priority of the generated volume migration plan, prioritizing, in a case where a periods of time during which the generated volume migration plan is executed and a period of time during which an existing volume migration plan is executed are overlapped with each other, and changing the start time of at least one of those volume migration plans having a lower priority.
