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.
摘要翻译：本发明涉及一种磁盘阵列控制器。需要大量的存储器件系统可操作而不中断。此外，为了应对最近开放系统的趋势，需要这种系统的性能和容量的可扩展性。通常，将一个将通道接口部分连接到共享存储器部分的内部总线和共享存储器部分的盘接口部分安装在一个盘片上，并且其上安装了通道接口和其他包装。如果内部总线出现故障，整个系统的运行必须停止。另外还有一个问题是内部总线的性能是固定的。根据本发明的磁盘阵列控制器包括其上安装有通道接口部分和磁盘接口部分的接口拼盘，其上安装有共享存储器部分的存储器盘片和将接口盘连接到存储器盘片的电缆以解决上述问题。

摘要： A disk array controller is made up of multiple disk array control units for implementing the data read/write operation and each having channel IF units, disk IF units, cache memory units and shared memory units. The disk array controller further includes inter connections for interconnecting the shared memory units and interconnecting the cache memory units across the border of disk array control units. Thereby alleviating the deterioration of performance due to the data transfer between the disk array control units, when the multiple disk array control units are to be operated as a single disk array controller.

摘要： The disk array controller includes a plurality of interfaces with respective processors for connecting with a host computer or disk devices, duplicated shared memories connected in a one to one ratio between each interface and respective access paths, a selector connected to the plurality of interfaces, and a cache memory connected to the selector. The number of access paths between the selector and the plurality of interfaces is greater than the number of access paths between the cache memory and the selector. Each processor performs dual writing in the duplicated shared memories.

摘要： When there is an access passing between unit disk controllers, the band of a mutual connecting network must be very large in order to exhibit the performance sufficiently, so that the cost is increased. In the present invention, the access number of a logical volume is monitored, the change of an access path is suggested to an upper class device, and the logical volume is moved or copied to each unit disk controller, so that the mutual connecting network is used mainly for copy of the logical volume, thereby reducing the necessary band.

摘要： A disk array control device 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.
