Problems solved by technology
In this way, although the computer system can obtain enough power to maintain normal operation, since each power supply is actually in the state of a small amount of power supply, for the power supply, it is difficult to implement a small amount of power supply or a large amount of power supply. Power conversion will cause more power loss during the power conversion process. Furthermore, the power module with backup function means that the power module has a non-starting power supply as a backup under normal operation. However, in this example, the power module turns on all the power supplies included in the power module under normal operation so that the power module does not have any power supplies that are not activated as The backup power supply has lost sufficient backup capability, that is, when any power supply fails, the power module will back up the detected power supply because there is no unstarted power supply for it to start. The detection of an abnormal power supply triggers the power module to start overload protection and closes its DC output voltage output, resulting in a sudden interruption of the calculation of these nodes of the computer system, resulting in the loss of important data. Therefore, it becomes a standby solved problem

A power management method is suitable for a computer system, and determines a rated output power of at least one DC voltage by two power supply units according to an output power parameter. The outputpower parameter is determined by one of the two baseboard management controllers according to the voltage amplitude of an alternating current mains supply; and by operating one of the two power supply units in a starting mode in an operation state, the other one of the two power supply units is controlled to operate in one of the starting mode and the non-starting mode according to the rated output power and the operation state of the two power supply units and the total load power of each application circuit.
Description
【Technical field】 [0001] The present invention relates to a computer system and a power management method, in particular to a computer system and a power management method for effectively providing a backup function of a power supply. 【Background technique】 [0002] A conventional computer system, such as a server cabinet, includes a power module and a plurality of nodes (Nodes), wherein the power module is composed of two power supplies. The nodes may be computing modules or storage modules, and the computing modules are, for example, general-purpose computing on graphics processing units (GPGPU). Each of the power supplies supports the CRPS (Common redundant power supplies) specification formulated by Intel Corporation, so that only one of the two power supplies is activated as the main power supply under normal operating conditions of the computer system In order to provide the power required for the operation of the nodes included in the computer system, and the other o...
