摘要： There are provided a storage device for outputting-data in such a manner that whether or not error correction has been made can be discriminated, and a data processing system in which a storage device finishes data to a data processing device in such a manner that whether or not the area management information has been corrected for errors can be discriminated and in which the data processing device discriminates whether or not the area management information has been corrected for errors in order to perform predetermined data processing. There is also provided a data processing method for the storage device and for the data processing system. If there is any error correctable by an error processing unit 26 in the area management information read out from the flash memory 21, the controller 27 furnishes the area management information to the error correction processing unit 26 and appends a flag indicating the fact of error correction to the area management information corrected for errors to output the resulting data.

摘要： In a CORBA partial restart system in a built-in device, a sole restart of a CORBA library, a server and a client can be carried out without restarting the whole built-in device. The client gives a notification that an accident or a defective condition arises in the CORBA library and the client itself to a control section. The server gives a notification that the defective condition arises in the CORBA library and the server itself to the control section. When receiving the notification of the defective condition, the control section stops processes of the client, the server and the CORBA library. The control section releases their memory areas when the memory areas are not released after stopping their processes. Then, the control section restarts the processes of the client, the server and the CORBA library. Constructors of the client and the server reserve the memory areas for their own uses. A memory controller produces memory information of the reserved memory areas.

摘要： The present invention provides a method for testing and diagnosing a cable modem termination system, using a hand-held computing device. The hand-held computing device establishes a connection with the cable modem termination system through a wireless infrared and radio frequency connection, a serial, or a local area network connection. After the connection is established, a set of commands residing in the hand-held device are transmitted to configure the cable modem termination system. The cable modem termination system sends back a response that is displayed on a command screen of the hand-held device to identify status and error messages. A cable modem termination system operator can send a set of configuration instructions to the cable modem termination system by utilizing stored sets of configuration instructions. Using the hand-held device allows easy accessibility in remote locations with limited space for diagnostics and equipment.

摘要： An invention is disclosed for intelligent load balancing in a mult-path computer system. Initially, an input/output (I/O) request to access the computer I/O device is intercepted. Then, to properly balance data path traffic, the number of I/O requests that have been sent along each data path of a plurality of data paths providing access to the computer I/O device is detected, and a failure probability is calculated for each data path paths based on the number of I/O requests that have been sent along each data path. A data path is then selected that has a failure probability lower than the failure probability of other data paths of the plurality of data paths and the computer I/O device is accessed using the selected data path.

摘要： A memory controller controls access to one or more memory units. The memory controller includes access control logic operable to receive a memory access request that references at least one memory address. It further includes a fake response record operable to record a fake response indication for an address for which a response is to be faked. The access control logic is operable on receipt of a memory access request to access the fake response record and to fake a response where a fake response indication for an address indicates that a response is to be faked. By providing such a faked response, an embodiment of the invention is able avoid multiple exceptions for the same memory location in a CPU. Also, by providing such a faked response, multiple bus errors for a memory location can also be avoided where a bus supports Direct Memory Access (DMA). The memory controller can be implemented in an integrated circuit. It can form part of a memory subsystem including the memory controller and at least one memory unit in an integrated circuit.

摘要： When a network element (NE) detects a trouble in an operation system (OpS) for operating the NE itself, a representative NE is determined among a plurality of NEs operated by this OpS. The representative NE selects a substitute OpS from other OpSs and transmits a request for operating the plurality of NEs to the substitute OpS. Thereafter, the plurality of NEs come under the operation of the substitute OpS. The substitute OpS operates the plurality of NEs based on the operation request.

摘要： A cluster implements a virtual disk system that provides each node of the cluster access to each storage device of the cluster. The virtual disk system provides high availability such that a storage device may be accessed and data access requests are reliably completed even in the presence of a failure. To ensure consistent mapping and file permission data among the nodes, data are stored in a highly available cluster database. Because the cluster database provides consistent data to the nodes even in the presence of a failure, each node will have consistent mapping and file permission data. A cluster transport interface is provided that establishes links between the nodes and manages the links. Messages received by the cluster transports interface are conveyed to the destination node via one or more links. The configuration of a cluster may be modified during operation. Prior to modifying the configuration, a reconfiguration procedure suspends data access requests and waits for pending data access requests to complete. The reconfiguration is performed and the mapping is modified to reflect the new configuration. The node then updates the internal representation of the mapping and resumes issuing data access requests.
