ABSTRACT:
Provided is a storage controller capable of changing a system configuration with scalability. A storage controller blade of the storage controller includes: interface units that each connect to one of a host computer and a disk device; a processor unit that controls a configuration of the storage controller and data access; a memory unit that stores a data cache and configuration information on the interface unit and the processor unit; and a mutual connection unit that connects the interface units, the processor unit, and the memory unit to one another. The processor unit recognizes a form of connection to another storage controller blade over the mutual network, and the connection path to another storage controller blade is set in the mutual connection unit based on the recognized form of connection.
