摘要:
A storage system adapted to be coupled to a plurality of host devices via a fibre channel. The storage system including a plurality of storage devices, at least a portion of the plurality of storage devices corresponding to a logical unit of a plurality of logical units, the logical unit having a logical unit number (LUN). The storage system also including a storage control device having a cache memory and controlling to store data, addressed to the LUN, into the portion of the plurality of storage devices. The storages system also including an input device being adapted to be used to set information, which is used to prevent an unauthorized access to the logical unit and which corresponds to a relationship between a host device of the plurality of host devices and the logical unit.

A method and apparatus for cached adaptive transforms for compressing data streams, computing similarity, and recognizing patterns have been disclosed.In one embodiment of the invention an encoder and decoder begin with a baseline transform. As data is transferred an algorithm is arranged so that the encoder and decoder adapt toward a superior basis than the baseline, with a corresponding reduction in the encoding bit rate. That is the algorithm adapts to the incoming data stream and can use a custom basis. We deliberately avoid having to send the custom basis itself (when possible), because sending the basis vectors consumes precious bandwidth and may defeat the goal of compression. The encoder and decoder can bootstrap themselves into using one or more better bases.In one embodiment of the invention there is no beginning baseline transform shared between the encoder and the decoder.

An exercising device comprises an operation module, a step module, and a seat module. The operation module has an operation unit. The step module has steps for bearing feet of the user, respectively. The step module is configured to move the step. The seat module has a seat and a driving unit configured to swing the seat. The step module and the seat module are detachably attached to the operation module. The exercising device has any one of a first condition, a second condition, and a third condition. The operation module is configured to hold the step module when the exercising device has the first condition. The operation module is configured to hold the seat module when the exercising device has the second condition. The operation module is configured to hold both the step module and the seat module when the exercising device has the third condition.

An oscillation-type exercise device is provided with a pair of reins on the right and on the left disposed in front of a user seated on a seat portion. Base ends of the pair of the reins are coupled to a pair of extensible mechanisms housed inside the seat portion. Handle portions to be gripped by the user are attached to tip ends of the pair of reins. Each extensible mechanism is configured to change the length of the reins, that is, each extensible mechanism causes the reins to generally extend and retract.

A method for verifying data in a storage system is disclosed. A host computer transmits area management data to a storage controller. The area management data specifies a range of a storage area in a storage device to be used by an application program having a mechanism for verifying data suitability. Upon receipt of an input/output request transmitted from the host computer, the storage controller performs verification, which is usually performed by the application program, of the data that is to be processed according to the data input/output request and to be input/output to/from the storage area, which is specified in accordance with the received area management data.

A storage controller facilitating extending storage capacity while suppressing investment related to storage capacity is provided. System configuration information, including content of a definition of a virtual volume having a storage capacity that is larger than a real storage capacity including the storage capacity of a storage device unit, and content of a definition of at least one of a real volume formed by dividing the real storage capacity, and a pool area, is stored. Based on the system configuration information, relevant data is written to or read from an address position in the storage device unit in response to a data input/output request from the host system designating an address in the real volume, and data is written to or read from the pool area in response to a data input/output request from the host system designating an address in the virtual volume other than the real volume.

N_Port_Name information capable of distinctly identifying a host computer has seen set in a microprocessor 42 of a storage controller 40 prior to start-up of host computers 10, 20, 30; upon startup of the host computers 10, 20, 30, when the storage controller 40 receives a frame issued, then the microprocessor 42 operates to perform comparison for determining whether the N_Port_Name information stored in the frame has been already set in the microprocessor 42 and registered to the N_Port_Name list within a control table maintained. When such comparison results in match, then continue execution of processing based on the frame instruction; if comparison results in failure of match, then reject any request.

An equipment management device manages one or more pieces of equipment which are connected to the equipment management device via a network. The equipment management device includes a determining unit which determines whether a non-authenticated software item exists in each of the one or more pieces of equipment, and a license management unit which performs license management of one or more software items installed in each of the one or more pieces of equipment, based on a result of the determination by the determining unit.
摘要:
A method for controlling a storage system including a host computer, and a first and a second storage control apparatuses each receiving a data input/output request from the host computer and executing a data input/output process for a storage device in response to the request, comprises connecting a first communication path between the host computer and the first apparatus; connecting a second communication path between the first apparatus and the second apparatus; receiving by the first apparatus a first data input/output request from the host computer through the first path; when the first apparatus has judged that the first request is not for the first apparatus, transmitting by the first apparatus a second data input/output request corresponding to the first request, to the second apparatus through the second path; and by the second apparatus, receiving the second request and executing a data input/output process corresponding to the second request received.
