Abstract:
PROBLEM TO BE SOLVED: To appropriately rearrange hard drives in response to the arrangement change of a plurality of hard drives and addition of logical drive units in a storage subsystem. SOLUTION: In a computer system, a storage subsystem A(18) is connected to an array controller, comprises the plurality of hard drives arranged in an ascending order. A plurality of logical drive units 20, 21 can be specified for the hard drives. The array controller determines whether or not arrangement of the hard drives is changed on the basis of configuration information including identification numbers of the hard drives, position numbers indicating positions, and information indicating an associated logical drive unit, and determines whether a hard drive related to a logical drive unit 20 is arranged in a non-ascending order on the basis of the configuration information. As shown in a storage subsystem A'(28), in the case of the non-ascending order, information for arranging the hard drives in the ascending order is provided to a user. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
A system with a plurality of devices compatible with the Fibre Channel Protocol, with at least one initiator/originator and one target/responder. The initiator/originator is provided with the capability to send both data and command frames to the target/responder to increase write performance. The target/responder allocates a portion of its Responder-Exchange-Identifiers for the write use of the initiator/originator, which manages the use of these identifiers.
Abstract:
A method of determining an object's position and associated apparatus provides positional information in a form that may be conveniently communicated to a computer to calculate the object's position. In a preferred embodiment, representatively incorporated in a computer keyboard, a method of determining an object's position includes forming an optical grid of reflected beacons and detecting an obstruction of the reflected beacons. A preferred embodiment apparatus utilizes a single light source to detect an object's position in two dimensions.
