Abstract

The invention provides a device for monitoring total power consumption of servers in real time. A precision resistor is connected between a hot plug redundant power supply and a power supply end of a PCB board in series; a hot plug controller is connected with two ends of the precision resistor and is used for measuring voltages at the two ends of the precision resistor; the hot plug controller is connected with a power management bus. All the output currents of the hot plug redundant power supply are collected onto the precision resistor; the voltages at the two ends of precision resistor are detected through the hot plug controller; the resistance value of the precision resistor is known, so that an input current value can be obtained according to an Ohm law and then input power consumption can be obtained; the power consumption is stored in a power register in a digital form through an A/D analog to digital manner, so that control chips such as BMC, PCH and the like in a system can read the value through PMBUS; and the value is a real-time summary of all the paths, so that the detection precision can be improved.

Description

technical field [0001] The invention relates to a real-time monitoring device and a monitoring method for the total power consumption of a server. [0002] Background technique: [0003] In the existing technology, the known technology is that the server system has very high requirements on efficiency, stability, and reliability. , the efficiency of the server is particularly important, usually the server has a variety of control mechanisms to improve system efficiency, but almost all of these implementation methods need to know the total power consumption of the system, usually the motherboard will read the hot plug through the power management bus PMBUS Check the power consumption of the redundant power supply PSU to know the total power consumption of the system. Under the PSU redundant architecture, it is necessary to read the power consumption of each PSU in turn through the PMBUS, and then perform cumulative calculations to obtain the total power consumption of the sys...
