Patent ID: 7802017

Claim:
A server device comprising: one or more server modules; one or more storage modules; a management module for managing a whole of the server device; and a back plane via which a signal is transmitted among the modules, said server modules, said storage modules, and said management module being installed in slots of said server device, wherein each of said one or more server modules and said one or more storage modules has a module management unit that controls power of its own module, said management module has an interface for identifying types of the modules installed in the slots, and stores information on connection between the one or more server modules and one or more storage modules on the back plane, when an installed one or more server modules and one or more storage modules is installed in the slot, said management module obtains a type of the installed module from the interface to store the obtained module type in a configuration information file, said management module compares the connection information with the configuration information file to generate an interlock relation between the one or more server modules and the one or more storage modules and stores the interlock relation as interlock configuration information, when receiving a request for turning on power of a target server module, said management module refers to the interlock configuration information to identify one of the one or more storage modules interlocked with the target one of the one or more server modules which is the target of the power-on request, said management module sends a power-on signal to the module management unit of the identified storage module to turn on power of the identified storage module; upon recognizing the power is on of the identified storage module, said management module sends a power-on signal to the module management unit of the target server module to turn on power of the target server module.
