Abstract: A power supplying method for a computer system is proposed. The computer system includes a first computer node, a first power supply unit corresponding to the first computer node, a second computer node, a second power supply unit corresponding to the second computer node, and a connection module electrically connected to the computer nodes and the power supply units. The power supplying method includes: detecting, by the first computer node, whether the second power supply unit operates abnormally; and upon detecting at least that the second power supply unit operates abnormally, controlling, by the first computer node, the first power supply unit to provide electric power to the second computer node through the connection module.

Abstract: A cross authentication method includes steps of: a host central processing unit (CPU) module sending to a baseboard management controller (BIC) a request for BMC signature; the host CPU module receiving BMC signature data from the BMC; the host CPU module determining whether the received BMC signature data is authentic based on a BMC public key stored in the host CPU module; and the host CPU module allowing the BMC to access the host CPU module when it is determined that the BMC signature data is authentic.

Abstract: A method for recovering a basic input/output system (BIOS) image file of a computer system is provided. The method includes steps of: controlling a switch unit of the computer system to switch from a first state to a second state when the BIOS image file is to be updated; reading a current BIOS image file so as to store the same as a backup; controlling the switch unit to switch back to the first state; determining whether a command is received within a first predetermined time period when the BIOS image file is successfully updated to a new version of the BIOS image file; and when negative, controlling the switch unit to switch to the second state and writing the backup of the current version of the BIOS image file.

Abstract: A method for remotely triggered reset of a baseboard management controller (BMC) of a computer system is disclosed. The computer system includes a first computer node and a second computer node. The method includes: (A) receiving, by a first BMC of the first computer node, from a computer device and via a network, a reset command which indicates that reset of a second BMC of the second computer node should be triggered; and (B) transmitting, by the first BMC and to the second BMC via electrical connection between the first and second BMCs, a reset signal that corresponds to the reset command, so as to trigger reset of the second BMC.

Abstract: A method includes: by an application executed by a first node, determining whether a non-transparent bridge between the first node and a second node is in a disconnected state; sending a re-initialization request from the application to a driver executed by the first node when the NTB is in the disconnected state; re-initializing a memory of the first node upon the driver receiving the re-initialization request; transmitting a result message related to the re-initialization of the memory to the second node; and implementing a memory-sharing procedure upon completing the re-initialization of the memory and receiving, from the second node, another result message related to re-initialization of a memory of the second node.

Abstract: A method for updating system information of a computer device is provided. The computer device includes a baseboard management controller (BMC) and a non-volatile memory. The method includes steps of: a) upon activation of the BMC, determining whether the BMC is in a power on reset (PoR) state, and obtaining current system information that is associated with the computer device; b) when it is determined that the BMC is in the PoR state, determining whether system information stored in the non-volatile memory conforms with the current system information; and c) when the determination made in step b) is negative, storing the current system information in the non-volatile memory.

Abstract: This application provides a server and a debugging method therefor. The debugging method for a server includes receiving, by a complex programmable logic device (CPLD), a control signal generated by a switching member, and generating a switching signal; and switching, by a bus switch, a communication connection of a communications port to a debug port or a Serial Over Lan port of a baseboard management controller (BMC) based on the switching signal. In this way, debugging work is completed or industrial control application information is received at the communications port.

Abstract: A method is provided for optimizing fan speed control of a computer system that includes a fan unit, a temperature sensor, a control unit to control operation of the fan unit, and a disk storage unit. A forbidden range corresponding to a range for a fan speed is determined based on a relationship between fan speed and vibration of the disk storage unit. An optimized fan control table is generated based on a reference table relating to a relationship between ambient temperature and fan speed. The optimized fan control table is generated by making a part of the ambient temperature values in the reference table change to corresponding to a predetermined fan speed not smaller than a fan speed value corresponding to an upper limit of the forbidden range.
