A synchronization method, which is capable of data synchronization in both directions between a storage medium and a storage unit, includes steps of: determining whether first parameter data of the storage medium is identical to default parameter data stored in the storage medium; determining whether a value of a flag stored in the storage unit is equal to a first logical value; and performing data synchronization between the storage unit and the storage medium based on at least one of the two determinations.

A method of supplying electric power to a computer system compliant with specification provided by the OCP is provided. The method includes: a PLU setting an OCP_V3_EN signal to a high level so as to make the computer system operate in a first mode; a BMC obtaining card data from an OCP card when the computer system operates in the first mode; the BMC determining whether standby power provided by a PSU in the first mode is sufficient according to the card data; and when it is determined that the standby power is not sufficient, the BMC controlling the PLU to make the computer system operate in a second mode requiring more electric power, and to then control the PSU to provide main power that is greater than the standby power to the OCP card.

A server rack includes a plurality of servers, each of which includes: a power management unit operable to convert a DC input voltage into at least one DC output voltage to output at least one type of DC output power; at least one application circuit for being respectively powered by the at least one type of DC output power; and a baseboard management controller cooperating with the power management unit to provide power management data. One of the baseboard management controllers of the servers is for receiving the power management data respectively from the other one(s) of the baseboard management controllers, and controls the power management units of the servers for power management of the servers based on the power management data.

A method for controlling a correctable error reporting function and applicable to a server device is provided, including: receiving, by control unit, a plurality of first error messages sent by a first hardware component in which a plurality of correctable errors occurs in a plurality of hardware components; determining, by the control unit, according to the first error messages, error types of the errors occurring in the first hardware component; determining, by the control unit, whether the number of occurrences of the errors of the error types that occur in the first hardware component within first preset duration reaches a preset number of times; and if the determining result is yes, controlling, by the control unit, the first hardware component to stop performing an error reporting function corresponding to the first error type.

A server rack assembly includes a pair of mounting units each including a panel, an adjustment plate, and rails. The panel has a first panel flange to connect a front support post. The adjustment plate is movably connected to the panel for connecting a rear support post and is adjustable to suit varying distances between front and rear support posts. The rails are detachably mounted on the panel; a gap between two rails is adjustable to accommodate different server devices.

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.

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.

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.

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.
