Abstract: A method of data synchronization is to be implemented by a redundant server system including an active input/output module (IOM) and a passive IOM. The method includes: allocating a primary transfer buffer in the active IOM; allocating a secondary transfer buffer in the passive IOM; collecting pieces of secondary dedicated-sensor data, and storing the pieces of secondary dedicated-sensor data in the primary transfer buffer at once; collecting pieces of primary dedicated-sensor data; after the pieces of primary dedicated-sensor data have been collected, updating the primary state data based on the pieces of primary dedicated-sensor data thus collected and the pieces of secondary dedicated-sensor data stored in the primary transfer buffer at once, and storing the primary state data thus updated in the secondary transfer buffer; and updating the secondary state data based on the primary state data that have been updated and that are stored in the secondary transfer buffer.

Abstract: A server and an updating method for a MAC address are provided in the present application. The server includes: a network chipset having a preset first MAC address; a first non-volatile memory storing the first MAC address of the network chipset; a second non-volatile memory storing a first BIOS code data; a central processing unit coupled to the network chipset and the second non-volatile memory; and a baseboard management controller coupled to the central processing unit, the first non-volatile memory, and the second non-volatile memory. The baseboard management controller reads the first non-volatile memory to obtain the first MAC address and stores a second BIOS code data including the first MAC address to the second non-volatile memory, causing the first BIOS code data to be overwritten by the second BIOS code data

Abstract: A method for protecting a server from damage by a liquid leak from a liquid-cooling unit of the server is provided. The server further includes a liquid leak sensor unit, a programmable logic circuit, and a power supply unit that supplies main power and standby power for the server. When a liquid leak is detected, the liquid leak sensor unit generates a main-power-off signal to the programmable logic circuit that causes the power supply unit to stop outputting the main power accordingly. The liquid leak sensor unit sends a total-power-off signal to the power supply unit to stop supply of the standby power after the power supply unit has stopped outputting the main power.

Abstract: A method of adjusting power consumption of a server is implemented by a baseboard management controller (BMC). The server includes the BMC and a processing module that are connected to each other. The BMC is connected to a power supply for receiving electrical energy supplied thereby, and the processing module operates based on the electrical energy thus received according to a current setting value of a power consumption limit. The method includes steps of: obtaining consecutive values of power conveyed by the power supply to the server; and based on the values of power currently obtained, adjusting the current setting value of the power consumption limit to be within a defined range.

Abstract: A system includes a host and a display. The host includes a programmable logic device (PIP), a baseboard management controller (BMC) and a switch. The PLD performs a power-on procedure based on a power-on sequence code, generates variable character information in the power-on procedure, and fills the variable character information into a variable field in a preset log text file to result in an updated log text file. When it is determined that the power-on procedure is not normally completed, the PLD controls the switch to switch to a debug mode, and transmits a video signal containing debug information corresponding to the updated log text file to the switch so that the video signal is outputted to the display.
