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.

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： The invention efficiently mounts substrates to back planes and accomplishes high quality signal transfer. Connectors to which N adaptor substrates are fitted and connectors to which M bus switch substrates are fitted are provided to a multi-layered back plane. Signal pin groups of the connector on the adaptor substrate side are grouped into M data paths. Signal pins of the connector on the adaptor substrate side and corresponding signal pins of the connector on the bus switch substrate side are arranged horizontally in such a fashion as to exist on the same plane (with positions in a Z direction being substantially equal). Therefore, wiring patterns for connecting corresponding signal pins can be formed substantially linearly and a large number of substrates can be efficiently mounted to a limited area.

摘要： A disk array control device which includes a plurality of channel interface (IF) units, a plurality of disk IF units, a cache memory unit, and a shared memory unit. The connection system between the plurality of channel IF units and plurality of disk IF units and the cache memory unit is different from the connection system between the plurality of channel IF units and plurality of disk IF units and the shared memory unit. In the invention the plurality of channel IF units and the plurality of disk IF units are connected via a selector to the cache memory unit whereas the plurality of channel IF units and the plurality of disk IF units are directly connected to the shared memory unit with no selectors.
