Abstract: A method for performing automatic system recovery is implemented by a server including a control chipset and a baseboard management controller (BMC). In the method, when a current image file is corrupted, a recovery engine generates an indicator of a version of the current image file and transmits the indicator to the BMC. The BMC then transmits a request for a backup image file to an external electronic device. After the BMC receives file link information of a disk image file from the electronic device, the BMC accesses the electronic device to download the disk image file, and mounts the disk image file as a virtual disk on the BMC. Afterward, the recovery engine replaces the current image file with the disk image file from the virtual disk.

Abstract: A power management method is adapted for a computer system that includes a CPU, a control unit, a BIOS and multiple PSUs. When one PSU operates abnormally, it sends an alert signal that is in an alert state to the control unit, and the control unit causes the CPU to operate under a predefined lowest power consumption limit. The control unit computes an updated power consumption limit, and notifies the BIOS to write the updated power consumption limit into a model-specific register of the CPU, so as to make the CPU operate under the updated power consumption limit.

Abstract: A method for reading information from multiple riser cards is implemented by a BMC module that includes an SMBus controller, where the riser cards are electrically connected to the SMBus controller. The method includes steps of: accessing a lookup table and a plurality of bus addresses; scanning a target address for communicating with a target card; determining whether a slave address has been received from the target card; when the BMC module determines that the slave address has been received from the target card, reading a memory of the target card according to a target reading spec to obtain identification information; determining whether the identification information conforms to an FRU header format; and when the BMC module determines that the identification information conforms to the FRU header format, reading the memory of the target card to obtain FRU information.

Abstract: An HA system includes a first IOM having a first switch, a second IOM having a second switch, and a plurality of slot modules configured to be connected to a plurality of SSDs, respectively. Each of the slot modules has Port A′ configured to be connected to the first IOM and Port B′ configured to be connected to the second IOM. In response to detecting a connection of one of the SSDs to one of the slot modules, the first and second IOMs determine whether the SSD is a single-port type SSD. When it is determined that the SSD is a single-port type SSD, the first IOM controls the first switch to link up to said one of the slot modules and the second IOM controls the second switch to unlink said one of the slot modules.

Abstract: A synchronizing system includes a phase-locked loop (PLL), first and second network controllers (NCs), a retimer and a processor. The PLL receives a local oscillator (LO) signal, generates and outputs a clock signal and a synchronizing signal. The retimer and the first and second NCs operate according to the clock signal. The first/second NC generates a first/second clock-event signal based on the synchronizing signal. The processor generates a first/second Precision Time Protocol (PTP) signal based on the first/second clock-event signal, and transmits the first/second PTP signal to the first/second NC. The second NC delivers the second PTP signal to first transceivers. The retimer performs retiming on the first PTP signal, and delivers the same to second transceivers. In a master mode, the PLL unit generates the synchronizing signal based on the LO signal and a reference time signal received from a global navigation satellite system (GNSS).
