摘要： Reduction of data processing capacity attributable to the occurrence of a failure is prevented by promptly identifying the failure location.A storage apparatus includes a plurality of expanders connected to storage media storing data sent from a host system, and a controller for controlling the expanders, wherein the controller sends a failure detection command to the plurality of expanders; the plurality of expanders store the command in their own storage units; and if one expander from among the plurality of expanders detects a failure in another expander immediately following and connected to the one expander, the one expander reads the command stored in a storage unit for the one expander and sends a response including failure detection information corresponding to the command to the controller.

摘要： The present invention comprises a memory, a plurality of access portions for accessing the memory, a memory adapter for controlling access to the memory from the plurality of access portions, and a response-type path (R path) and a throughput-type path (T path) which communicatively connect the respective access portions, and the memory adapter. The amount of information capable of being transferred by the R path within the same period of time is smaller than that of the T path, but the length of time from the sending of information until the receipt of a response thereto is shorter for the R path than for the T path. The length of time from the sending of information until the receipt of a response thereto is longer for the T path than for the R path, but the amount of information capable of being transferred by the T path within the same period of time is greater than that of the R path. The memory adapter preferentially allows access to the memory via the R path than access to memory via the T path.

摘要： This invention relates to a disk array controller. There has been demand for a large scale memory device system operable without interruption. Further, in order to cope with the recent trend toward open systems, scalability of performance and capacity in such systems is needed. Conventionally, internal buses such as ones which connect the channel interface section to the shared memory section, and the disk interface section to the shared memory section, have been mounted on one platter, and the channel interface and other packages have been mounted thereon. If the internal buses have failed, the operation of the whole system must be stopped. There has been another problem that the performance of the internal buses is fixed. A disk array controller according to this invention comprises an interface platter on which a channel interface section and a disk interface section are mounted, a memory platter on which a shared memory section is mounted, and a cable which connects the interface platter to the memory platter in order to solve the above problems.

摘要： According to the present invention, in cases where a CHA function and a DKA function are mounted within a single package, a battery power supply that is used during the occurrence of power supply trouble is effectively utilized so that the supply of power can be separately controlled for each function. A CHA part and DKA part are disposed in a single control package. When trouble such as a power outage is detected, the CHA part blocks access requests from the host, and initiates end processing. When the end processing of the CHA part is completed, the package internal power supply control part stops the clock supply to the CHA part. Then, when the DKA part completes destage processing, the package internal power supply control part stops the supply of power to the DKA part. The power consumption of the package is lowered in stages in accordance with the progress of the end processing.

摘要： A PLD is interposed on the communication route between a microprocessor (hereinbelow called MP) and boot memories. The boot memories store MP start-up data needed to start up the MP and start-up protection code constituting protection code for the MP start-up data. The PLD reads the MP start-up data and the start-up protection code thereof from the boot memories, performs, in hardware fashion, a check of the validity of the MP start-up data using this start-up protection code and, if a negative check result is obtained, resets the MP and if a positive check result is obtained, inputs the start-up data that is thus read to the MP.
