Abstract: A simulation method for realizing large batches and different kinds of baseboard management controllers using a single server includes providing a virtual baseboard management controller by a target terminal according to different customized virtual baseboard management controller resources correspondingly. The simulation method includes initializing large batches and different kinds of virtual baseboard controller programs according to a customizable virtual baseboard controller resource. If a client requests to access one baseboard controller or multiple baseboard controllers, which virtual baseboard controller will provide a service is determined according to the information of the accessing request of the client. Then an output result is generated according to the behaviors defined in the customized resource. Finally, the output result is transferred to the client. Therein, the client may connect to the target terminal through Internet or a bus.
