Abstract: A computer system includes multiple hard disk devices, a hard disk device backplane, an information management unit, a middle backplane and multiple motherboards. The hard disk device backplane is coupled to and configured to manage the hard disk devices. The information management unit, coupled to the hard disk device backplane, is configured to acquire statuses of the hard disk devices. The middle backplane is coupled to the hard disk device backplane. The motherboards, coupled to the information management unit and the middle backplane, respectively have a baseboard management controller. When the operating system is loaded for operation on the motherboards, the baseboard management controllers are coupled to the hard disk device backplane via the middle backplane to acquire the statuses of the hard disk devices. When the motherboards are not operated normally, the baseboard management controllers acquire the statuses of the hard disk devices via the information management unit.

Abstract: A power distribution method suitable for a server system is provided. In the method, an average power is respectively supplied to activated motherboards, an expected power of each activated motherboard is read, and the expected power and the average power are compared, where if the expected power is greater than the average power, a first state is defined, and if the expected power is less than the average power, a second state is defined. Then, the expected powers of the motherboards defined as the second state and the average power are calculated to obtain a first remaining power. Then the first remaining power is averagely distributed to the motherboards defined as the first state. This method is capable of dynamically distributing power according to the needs of each of the motherboards and providing sufficient powers to the motherboards for operation.

Abstract: A server integrating system contains at least one rack, and the rack contains servers and a rack management board. The rack management board is connected to the chassis management board through a transmission line, in which the chassis management board sends the information of the servers to the rack management board, and the chassis management board passes the data to the rack management board.

Abstract: A computer system displays and controls the hard disk condition. The computer system includes a host bus adapter which detects the status of the hard disk, and the status light gives light to display the hard disk status. The baseboard management controller and the host bus adapters are set on the motherboards, in which the baseboard management controller monitors and records the status of the hard disk. The microcontroller is set on the hard disk backplane for decoding the message from the host bus adapter in order to control the displaying of the status light.

Abstract: A computer system contains motherboards, chassis management board and functional components. The motherboards have a micro control unit, and the functional components are electrically connected to the chassis management board, in which the micro control unit processes the data and passes the processed data to the chassis management board through a transmission line. The chassis management board receives and decodes the information from the micro control unit, then the chassis management board transmits the decoded information to the functional elements. The chassis management board also receives and passes the information returned from the functional components to the micro control unit through the transmission line.

Abstract: A computer apparatus includes a first power supply, a first power distribution board, a second power supply, a second power distribution board, motherboards, and a control module. The first power supply provides a first power. The first power distribution board is coupled to the first power supply to transmit the first power. The second power supply provides a second power. The second power distribution board is coupled to the second power supply to transmit the second power. Each of the motherboards generates a working state. The control module coupled to the first power distribution board, the second power distribution board, and the motherboards determines whether to generate a control signal based on the working states of the motherboards and a working state of the first power supply and/or a working state of the second power supply to enable a power throttling feature to adjust power consumption of the motherboards.
