Abstract: The present application discloses a power supply redundancy control system for a GPU server, comprising a power supply redundancy module, a BMC, a CPLD and a GPU module. The power supply redundancy module comprises a first PSU and a second PSU, and the GPU module comprises several GPUs, the first PSU is connected to the CPLD by means of a first bus. The second PSU is connected to the CPLD by means of a second bus. The BMC is connected to the CPLD by means of a first I2C bus and a second I2C bus, and sends heartbeat information to the CPLD. The CPLD is connected to the BMC by means of a third bus and a fourth bus, and the CPLD is connected to the several GPUs by means of a third I2C bus. In the present application, when the BMC is abnormalous or restarted, the CPLD can control the overall power consumption of the server, and can also ensure that the server will not go down, reducing the loss brought to a user due to the BMC being abnormalous or restarted.

Abstract: An out-of-band updating method and system of an Expander, applied to a controller connected to the expander by means of a communication bus. The method comprises: receiving firmware updating data sent by a user (S101); fragmenting the firmware updating data (S102); and only when determining that the expander is in an idle state, sending the fragmented data until each piece of data is sent to the Expander, such that the expander completely receiving the firmware updating data completes updating by restarting (S103). The data transmission speed is facilitated to be improved, the normal operation of a service is ensured, and the conditions of influencing state monitoring and log loss are avoided.

Abstract: A heat dissipation control method is disclosed, wherein the heat generation speed of a heat dissipation channel may be calculated according to a power consumption value of each component in the heat dissipation channel, and a radiator is then controlled on the basis of the heat generation speed, whereby the heat dissipation speed of the heat dissipation channel is comparable to the heat generation speed. A heat dissipation control apparatus and device are further disclosed, which have the same beneficial effects as the heat dissipation control method.

Abstract: A server firmware self-recovery system and a server. The system includes a storage module, a starting controller, a repair controller, and a logic controller. The storage module is configured to store a system firmware program. The starting controller is configured to read, when establishing a communication connection with the storage module, the system firmware program from the storage module to start the system. The repair controller is configured to perform abnormality repair processing on the storage module when the storage module starts abnormally and the repair controller establishes a communication connection with the storage module. The logic controller is configured to establish a communication connection between the storage module and the starting controller by default in an initial situation. If the starting controller fails to start the system, the storage module starts abnormally, and the storage module is switched to establish a communication connection with the repair controller.

Abstract: Provided are an allocation method, system and device for power consumption of a complete machine box, and a readable storage medium. The method, applied to a CMC, includes: determining reserved total power consumption, based on rated power consumption of an integral chassis and preset power consumption of each node; allocating the preset power consumption to each node correspondingly; detecting, at a detection frequency, actual power consumption of each node; and re-allocating, for each node, the reserved total power consumption and the preset power consumption of the node, based on a rate of change in the actual power consumption of the node and/or a power consumption utilization ratio that is a ratio of the actual power consumption of the node to the preset power consumption of the node, thereby maximizing the effective utilization ratio of the integral chassis, reducing the unused power consumption, and reducing operating cost.
