Abstract
The present invention provides a server system capable of monitoring power consumption of a Peripheral Component Interconnect Express (PCIE) device with high precision, relates to the fields of cloud computing and data centers. Supply voltages of PCIE slots comprise 12V and 3.3V. 12V supply currents and 3.3V supply currents flowing through all PCIE slots of the system are sensed by using precision resistors. Then, a power consumption monitoring device Power Monitor converts sensed currents and voltages into power consumption values. Finally, power consumption data is output to a baseboard management controller (BMC) of the system through an I2C bus. Then, the BMC adds the power consumption data of power supply links of 12V and 3.3V, and displays obtained total PCIE device power consumption on a Web management system interface. The real-time power consumption of all PCIE devices of the system under different pressure provides an accurate and intuitive data basis for the server operation and maintenance personnel to manually adjust the rotation speed of fans.
Description
Technical field
The present invention relates to cloud computing and data center field, be specifically related to a kind of server system with high precision PCIE device power consumption monitoring.
Background technology
Along with the rise of the new industry such as cloud computing and large data, Internet enterprises and cloud computing service supplier are setting up increasing data center, have disposed or be about to the server disposing thousands of in each data center.Energy consumption and the heat radiation cost of data center become one of prime cost of above-mentioned enterprise gradually, and the relation balanced between server system energy consumption and heat radiation is very necessary.
Therefore, for server system, not only requirement can realize Overall Power Consumption monitoring function, also needs to realize: the power consumption of critical piece in difference supervisory system, such as: CPU, internal memory, hard disk, PSU, fan, PCIE device etc.
The real time power consumption monitoring function of what current industry was many realize CPU, internal memory and PSU, only has the power consumption monitoring function that small part manufacturer server can realize the parts such as hard disk, fan.But current industry not yet recognizes that PCIE device is also one of important parts of server system, and be one of parts that server system power dissipation ratio is larger.Therefore, in server system, the real time power consumption monitoring function realizing PCIE device can fill up the technological gap in this field.
Summary of the invention
In order to solve this problem, propose a kind of server system with high precision PCIE device power consumption monitoring herein.Based on the server system of this function, user can be helped to understand the real time power consumption of the PCIE device of system configuration, optimization system heat sink conception.The no matter any function of digital control system allocation, model and any amount of PCIE device, and PCIE device is under any operating pressure, server can be real-time, read PCIE device total power consumption under current configuration accurately, and out check for user in system Web interface display, and based on this data-optimized systems heat sink conception.
The technical scheme that the present invention takes is as follows:
PCIESlot supply voltage comprises 12V and 3.3V; 12V supply current and the 3.3V supply current of all PCIESlot of system is flow through by precision resistance Sense; Pass through power consumption monitoring device PowerMonitor again Sense electric current and photovoltaic conversion power consumption value; Finally, by I2C bus, power consumption data is exported to the BMC of system; The power consumption data of being powered on link by 12V and 3.3V by BMC is again added, and drawn PCIE device total power consumption is presented at web administration system interface.
9 I2C interfaces of BMC can select one of them arbitrarily as required, and PowerMonitor device needs to support standard P Mbus instruction, and host computer BMC directly reads power consumption number from PowerMonitor by the PMbus instruction of standard.
It should be noted that two PowerMonitor for 12V and 3.3V will distinguish its I2C address.Further, in order to improve the precision of power consumption monitoring, need at chip internal, calculating average power consumption unitary sampling rate to be arranged to maximum.By surveying and calibrating, the PCIE device power consumption precision that BMC reads can control within ± 1%.
Secondly, system software aspect, is designed to human-computer interaction interface at the remote administrative interface of BMC.Point open power menu bar can see current system configuration operation under PCIE device power consumption.
The invention has the beneficial effects as follows
The no matter any function of digital control system allocation, model and any amount of PCIE device, and PCIE device is under any operating pressure, server can be real-time, read PCIE device total power consumption under current configuration accurately, and out to check for user in system Web interface display.
System can to all PCIE device of carry on its PCIESlot carry out power consumption real-time, monitor accurately;
PCIE device in system is not limited to 1 or several specific model and kind, can arbitrarily change various PCIE device according to user's request, and does not affect its power consumption monitoring precision after changing;
The realization of power consumption monitoring function depends on the I2C controller of BMC chip on mainboard;
Power consumption monitoring principle flows through 12V electric current on all PCIESlot of system and 3.3V electric current by precision resistance Sense, and then both are calculated the power summation of gained, and result of calculation is sent to the BMC system of mainboard by I2C bus, by BMC, power data is presented in Web interface intuitively.
