Patent ID: 8726049

Claim:
A computer system comprising a plurality of computer modules each of which comprising a baseboard management controller, comprising: a state machine for monitoring a power state of power of each of the computer modules and a state of the baseboard management controller of the computer module; a plurality of modules of shared sections to be shared among the computer modules; and a plurality of switches corresponding to the modules of shared sections for selecting one of the baseboard management controllers and for establishing connections between the baseboard management controllers and the modules of shared sections, wherein at occurrence of an abnormality in the power state of any one of the computer modules or in the baseboard management controller of any one of the computer modules, the state machine comprising a hardware circuit dynamically conducts a switching operation to designate one of the baseboard management controllers without any intelligent management module independent of computer modules which select and switch baseboard management controllers to monitor sensors of the modules of shared sections.
