Abstract

The invention discloses a control device and a control method for a voltage regulation module VRM. Compared with the prior art, the method has the advantages that the cost is low. A standby power supply standby is added. The CPLD is connected with the voltage regulation module VRM. The CPU is connected with the voltage regulation module VRM and is used for providing power transmission requirementsfor the voltage regulation module VRM; wherein the baseboard management controller BMC is connected with the voltage regulation module VRM, and the switch is connected with the baseboard management controller BMC and used for controlling on-off between the standby power supply standby and the voltage regulation module VRM. the baseboard management controller BMC controls the switch to be switchedoff when monitoring that the voltage value of the voltage regulation module VRM is smaller than a first preset value; Normal interaction between the voltage regulation module VRM and the CPU is guaranteed when the system is restarted, and the problem that system restarting fails due to the fact that the voltage regulation module VRM cannot output power is solved.

Description

technical field [0001] The invention relates to the technical field of server hardware monitoring, in particular to a control device and a control method of a voltage regulation module VRM. Background technique [0002] With the rapid development of server technology, the operating frequency of the whole machine is getting higher and higher, and the rising rate of working current is getting faster and faster, which requires a lot of dynamic energy. Therefore, the voltage regulator module VRM (Voltage RegulatorModule) with high efficiency and high dynamic characteristics has been obtained. a wide range of applications. [0003] figure 1 It is a schematic diagram of the connection structure and signal transmission of the voltage regulation module VRM in the prior art. Such as figure 1 As shown, in the modern server design, the voltage regulation module VRM 101 is arranged between the power supply 102 and the CPU 103 , and is connected with the CPLD 104 and the baseboard man...
