Abstract: A main data center with first and second backup data centers also has a translator for assisting a failover module of a failed server at the main data center in implementing failover of the failed server to a corresponding server at the first backup data center. The translator intercepts a command from the failover module to a store of the main data center, where the command directs the store to disable writes to particular storage space in the store associated with the failed server, but does not identify with specificity which of a store of the first data center and a store of the second data center is enabled to write to such particular storage space. Thus, the translator determines an identification of the store of the first backup data center, and modifies the command from the failover module based on the determined identification.

Abstract: A mirror destination storage server receives mirror update data streams from several mirror source storage servers. Data received from each mirror is cached and periodic checkpoints are queued, but the data is not committed to long-term storage at the mirror destination storage server immediately. Instead, the data remains in cache memory until a trigger event causes the cache to be flushed to a mass storage device. The trigger event is asynchronous with respect to packets of at least one of the data streams. In one embodiment, the trigger event is asynchronous with respect to packets of all of the data streams.

Abstract: Apparatus methods for capturing flow control errors in FIFO exchanges between producing and consuming circuits operating in different clock domains. Tag information at the start of an exchange is transferred to a synchronizing component before data of a transfer transaction is entered in the FIFO. The tag information is also associated with each unit of data transferred to the FIFO by the producing circuit. The synchronizing component verifies the each unit of data retrieved by the consuming circuit has the expected tag information associated therewith and signals an error is the tag information does not match. Thus an error by the producing circuit in entering too much or too little data for a transfer is detected before erroneous data is retrieved and processed by the consuming circuit.

Abstract: Methods and apparatus dynamically reconfigure storage or channel capacities in a memory system. A fully-buffered dual in-line memory module (DIMM) is configured for a particular storage capacity and a particular channel capacity. An error may be detected at a memory address in some portion of the DIMM. To resolve the problem, the storage capacity or the channel capacity may be reduced and the DIMM may be dynamically reconfigured according to the reduced capacity. For one embodiment the DIMM may be reconfigured by mapping the portion of the DIMM containing the error as unavailable and taking that portion off-line without taking the entire DIMM off-line. For another embodiment the DIMM may be reconfigured by throttling the DIMM at a reduced frequency. The portion of the DIMM containing the error may be retested at the reduced frequency. If no errors are detected, the DIMM may be made available at the reduced frequency.

Abstract: To provide a mobile terminal apparatus with the lower communication cost in sending a log at the occurrence of a malfunction, abnormality or fault in the mobile terminal apparatus to a network. A diagnostic process for the malfunction is performed in accordance with a diagnostic policy acquired from the outside. An error code corresponding to the diagnostic result is generated. The generated error code is outputted. With an automatic fault diagnostic function of automatically analyzing the fault in the mobile terminal apparatus without directly sending the log collected in the mobile terminal apparatus to an analytic server, the communication cost can be reduced.
