Abstract: A NAS as a main machine transmits a search packet for searching for a NAS as a new backup machine when a response from a NAS as a backup machine is not received. Each of NAS receiving the search packet transmits a device information packet to the NAS as the main machine. The device information packet includes a version number of failover function and storage capacity information. The NAS as the main machine selects a NAS as the new backup machine based on the version number and the storage capacity information included in the device information packet.

Abstract: A failover information management device manages information on a failover system including two storage processing devices to each of which a storage medium is connectable. The failover information management device stores unsuitability information from which a combination of two storage processing devices determined to be unsuitable for constituting the failover system is identifiable.

Abstract: A storage processing device to which a storage medium is connectable configures a failover system together with a different storage processing device. The storage processing device sets information obtained from predetermined random information as identification information of the storage medium, at the start to configure the failover system.

Abstract: A storage system is capable of configuring a failover system by use of a first storage processing device to which first storage media are connected and a second storage processing device to which second storage media are connected. The storage system sets the RAID level of the second storage media to a RAID level with lower redundancy than the RAID level of the first storage media, if the storage capacity of the second storage media is smaller than the storage capacity of the first storage media.

Abstract: A method and apparatus for managing a folder is provided. The method includes: setting a drive correspondence table showing a correspondence relation of first location information including location information of an apparent drive allocated to the folder in the operating system and second location information including location information of a target drive to be actually allocated to the folder; and changing, in response to a request for an access to the folder requested by the operating system, location information allocated to the folder from the first location information of the apparent drive allocated to the folder to the second location information of the target drive allocated to the folder in accordance with the drive correspondence table without notifying the operating system of a change of location information of the drive allocated to the folder, whereby enabling the operating system to consequently access the folder in the target drive.

The network-connectable device includes: a mode selector configured to select a power mode between a first power mode and a second power mode; a power state switching unit operable on the first power mode and configured to: turn on power of the network-connectable device when one of the computer-related devices is connected to the network in a state where no computer-related device has been connected to the network; and shut down the power no computer-related device is connected to the network; and a power state maintaining unit operable on the second power mode and configured to maintain the power of the network connectable device in a same state regardless of whether the computer-related devices are connected to or disconnected from the network.

Abstract: A storage apparatus includes a storage unit including plural storage media, and a controller for controlling the storage unit. After a new storage medium has been added to the storage unit, the controller causes the new storage medium to store error correction codes for data stored in the respective storage media pre-existing in the storage unit. When new data is stored in the storage unit after the addition of the new storage medium, the controller causes the pre-existing storage media and the new storage medium to dispersedly store the new data and error correction codes for the new data.

Abstract: A storage processing device to which a plurality of removable hard disk drives and the like are connected and includes: a RAID controller for controlling RAID including the removable hard disk drives and the like, and an available storage capacity setting unit for setting an available storage capacity which is a storage capacity actually available for a predetermined storage unit that is one of the storage units connected to the storage processing in the disk array, on the basis of the real storage capacity of the predetermined storage unit, when the predetermined storage unit is connected to the storage processing device.

Abstract: The NAS 20 to which the removable hard disks 251 and 252 each storing an operating system are connected, assumes that the removable hard disk storing the signature of the NAS 20 stores an operating system executable on the NAS 20. Thus, the NAS 20 selects as a boot drive the removable hard disk storing the signature of the NAS 20 and then boots up the operating system stored in the boot drive thus selected.

Abstract: A storage apparatus in which at least a first storage medium and a second storage medium are installable and only the first storage medium is initially installed, the storage apparatus including a redundancy unit for executing a redundancy operation in which the same data is stored in both of the installed first storage medium and the second storage medium, and a controller for controlling the redundancy unit so that the redundancy unit can execute a restricted operation in which data is stored only in the first storage medium, until the second storage medium has been installed. The controller controls the redundancy unit so that the redundancy unit can return from the restricted operation to the redundancy operation after the second storage medium has been installed.

Abstract: A similarity degree estimation method is performed by two processes. In a first process, an inter-band correlation matrix is created from spectral data of an input voice such that the spectral data are divided into a plurality of discrete bands which are separated from each other with spaces therebetween along a frequency axis, a plurality of envelope components of the spectral data are obtained from the plurality of the discrete bands, and elements of the inter-band correlation matrix are correlation values between the respective envelope components of the input voice. In a second process, a degree of similarity is calculated between a pair of input voices to be compared with each other by using respective inter-band correlation matrices obtained for the pair of the input voices through the inter-band correlation matrix creation process.

Abstract: The cartridge-type HDD 200 to which the operation member 250 is attached is inserted into the slot 150. On this occasion, if in the first placement mode in which the head member 252 is situated on the rear side in the insertion direction of the cartridge-type HDD 200, the operation member 250 does not contact the switch 154. Accordingly, the cartridge-type HDD 200 is in the writable state. On the other hand, if in the second placement mode in which the head member 252 is situated on the front side in the insertion direction of the cartridge-type HDD 200, the operation member 250 presses the switch 154. Accordingly, the cartridge-type HDD 200 is in the write inhibit state.

Abstract: When inserted in the slot 150 of the storage unit main body 100, the cartridge-type HDD 200a is situated with the slight clearance between the protrusion 164 of the slot 150 and the upper surface of the cartridge-type HDD 200a. In addition, the protrusion 166 of the slot 150 is loosely fitted in the recess 216 of the cartridge-type HDD 200a.

Abstract: In a sample cell that is sealed with an X-ray transmission sheet after a sample such as a liquid fuel or the like is contained therein, when an internal pressure is increased, a cup end surface is deformed so as to increase an internal capacity of the sample cell before the X-ray transmission sheet serving as a window part is expanded. The cup end surface is formed by folding a film-like material and, when the internal pressure of the sample cell is increased, the cup end surface is unfolded outwardly of the sample cell to increase the internal capacity of the sample cell. The increase in pressure is relieved by the increase in capacity, and the expansion of the X-ray transmission sheet is thereby prevented.
