摘要： A power supply with an inverter capable of avoiding the inverter from producing excessive high voltage when a load is detached or the load impedance is greatly increased. The inverter is energized by a fixed DC voltage source and includes at least one switching element and an L-C resonant circuit. The switching element is driven to turn on and off and cooperative with the L-C resonant circuit to produce a high frequency AC voltage at an inverter output for driving a load. The inverter includes first and second clamping diodes connected in series across the DC voltage source in anti-parallel relation thereto with the first and second diodes defining therebetween a first connection point. Also included in the inverter is a pair of first and second impedance elements which are connected in series across the inverter output to provide a divided voltage indicative of an output voltage of the inverter with the first and second impedance elements defining therebetween a second connection point. The first and second connection points are connected to each other so as to keep the points at a voltage level nearly equal to a fixed voltage of the DC voltage source, in such a manner as to limit the output voltage of the inverter below a predetermined level by allowing a clamping current to flow through the first and second diodes and impedance elements and through the DC voltage source to escape the excessive voltage developed in response to the increase in the impedance of the load.

摘要： A control condition is automatically generated by using a discovery domain managed by an iSNS server as a network communication quality control unit and set in a network device. Thus, it is possible to realize communication whose quality is effectively controlled in storage data transmission. A network configuration server automatically acquires discovery domain information which groups a host and a storage apparatus managed by a name management server. The network configuration server sets a flow identification condition so as to identify the flow per discovery domain according to the information acquired, assigns a service class performing a control of quality of communication service to the flow, and sets transmission rule for the service class to routers.

摘要： A job control terminal creates a unit configuration table indicating the configuration of units connected to each of a plurality of processors in a multi-processor system. The job control terminal also creates an operating state table indicating an operating state of each processor including a CPU using ratio, I/O using ratio, memory using ratio, response time, and so on. When the job control terminal receives electronic mail for requesting job execution from a user through an electronic mail terminal, the job control terminal selects a processor assigned to execute the requested job based on the unit configuration table and the operating state table. When it is determined from the states of the processors that the requested job cannot be executed, information indicating that the job is unacceptable is transmitted from the job control terminal to the electronic mail terminal.

摘要： In a system which manages path information and status of network with respect to a path being used for access to a storage apparatus and has a redundant path, when a fault occurs in the network, whether or not the path can be recovered by rerouting in network apparatuses is discriminated, thereby performing proper path switching. Construction information and the path information of the network are managed as information of the path which is being used for a storage access by a management server. Further, when the access path is made redundant, the management server obtains fault information in the network and information showing whether or not the path is being reconstructed from the network apparatuses, thereby discriminating the necessity of the path switching. If the path switching is necessary, the management server notifies a host computer and the storage apparatus of it and each apparatus executes a switching process.

摘要： The present invention decreases the burden of operation required for specifying the continuity status and the cause of failure of a network storage device. A host computer accepts the specification of the device identifier, that is an identifier of the network storage device in the host protocol which positions in a higher hierarchy than the network communication protocol, and a volume identifier, that is an identifier of the volume. Then based on the specified device identifier, the host computer specifies the network identifier, that is an identifier of the network storage device in the network communication protocol. And continuity is confirmed in the network communication protocol in which the specified network identifier is the destination. Also continuity is confirmed in the host protocol in which the device identifier is the destination. And the volume specified by the volume identifier is accessed.

摘要： In an arrangement of a mail terminal 1, an electronic mail system 2, a job control terminal 4, and a computer system 3, a user makes a proposal of a file operation via a mail by way of the mail terminal 1. The electronic mail system 2 stores therein the proposal mail, exchanges this proposal mail with the job control terminal 4, and furthermore distributes a file operation result to the respective mail terminals. The job control terminal 4 receives a mail from the electronic mail system 2, and interprets the proposal mail, thereby executing a conversion from a mail ID into a host ID, a judgement of an access authorization with respect to the designated file, and a production of an instruction to the computer process system 3. Furthermore, an execution host computer is selected by monitoring operation conditions of the host computers. When the file operation result is sent from the computer process system 3, a mail containing this file operation result is produced, and the resultant mail is sent to the electronic mail system 2. The computer system 3 interprets a command issued from the job control terminal 4, thereby executing a reading operation from the designated file, a writing operation to the designated file, and a reading operation of a file name list.
