Abstract
Embodiments of the present invention provide a data storage system that reduces a load of a data bus for connecting a HOST system with the data storage system. The data storage system includes a disk manager connected to the HOST system by a SCSI BUS, connected to a disk control unit by an RS PORT and connected to disk enclosures and a fan unit by a Serial BUS. The disk manager monitors operation of the disk control unit and disk enclosures and transmits results to the HOST system. In addition, control commands of the HOST system to the disk enclosures are executed via the disk manager.
