The present invention provides a server including a plurality of power supplies independent from each other, a management backplane, a first embedded management board (first EMB) and a plurality of motherboards independent from each other. The power supplies are turned on or off according to a first control signal. The management backplane is coupled to the power supplies, the first EMB and the motherboards. The first EMB has a power-controlling unit and produces the first control signal and an acknowledgement signal according to the load status, the quantity of a plurality of turned on power supplies and a power-on demand command. The motherboards respectively send out the power-on demand command and decide whether or not to power on according to the acknowledgement signal, wherein when the first EMB works, a polling mode is used to sequentially switch the connections between the first EMB and the motherboards through the management backplane.

Server with an embedded management board having a power controlling unit for controlling a plurality of power supplies and motherboards independently

The present invention provides a server system comprising a first group of mainboard modules and a second group of mainboard modules, each of the first and second groups of mainboard modules including a plurality of mainboard modules. Each mainboard module includes a mainboard and a daughter board electrically connected to the mainboard; a first adaptor and a second adaptor; a hard disk array including a hard disk backplane and a plurality of hard disks, wherein the hard disk backplane is electrically connected to the first adaptor and the second adaptor; a first power control board and a second power control board respectively connected to at least one power supply, wherein the first power control board and the second power control board are electrically connected to the hard disk array; and a management board electrically connected to the first adaptor and the second adaptor.

Server system having mainboards

A multi-motherboard server system, having a management board and a plurality of motherboards, is disclosed. The multi-motherboard server system is applicable to a sever system. The management board has a BMC, and the motherboards are respectively connected to the management board. The BMC can transmit data to a far-end control system through sideband communication.

Multi-motherboard server system

A BIOS architecture adapted in a computer system is provided. The BIOS architecture includes at least one BIOS, a programmable chip module, a baseboard management controller (BMC), a south bridge chip and a network interface controller (NIC). The NIC is connected to the south bridge chip and the BMC and is to receive a remote update data to determine the destination of the remote update data. When the destination of the remote update data is the south bridge chip, the south bridge chip updates the BIOS according to the remote update data. When the destination of the remote update data is the BMC, the NIC informs the BMC to receive the remote update data, such that the BMC controls the programmable chip module to update the BIOS according to the remote update data.

BIOS architecture

A computer system adapted to connect a plurality of external servers is provided. The computer system includes a motherboard module, a power supply module, a baseboard management controller (BMC), a control module and a plurality of graphics processing units (GPUs). The motherboard module includes a plurality of first connectors and a plurality of second connectors, wherein the second connectors are respectively connected to the external servers. The power supply module is coupled to the motherboard module for supplying power to the computer system. The control module is disposed on the motherboard module, and the control module manages corresponding relations of the first connectors and the second connectors, and controls the power supply module to supply power to the first connectors. The GPUs are respectively coupled to the first connectors. Each of the GPUs correspondingly expands a computing capability of the external server through the corresponding second connector.

Computer system

A computer system including a power supply, a plurality of mainboards, and a power controller is provided. Each of the mainboards corresponds to a standby voltage, respectively. The power supply generates a standby power, and generates a main power according to a power enabling signal. The power controller is coupled between the power supply and the mainboards, for generating the power enabling signal and a control signal according to whether an amount of the mainboards is greater than a predetermined value, and selectively outputting the control signal to at least one of the mainboards. When the mainboards receive the control signal, regardless being in a booting state or a non-booting state, the mainboards receive the main power and converts the main power into a standby voltage corresponding thereto. When failing to receive the control signal, the mainboards convert the standby power into the standby voltage corresponding thereto.
