Abstract
The invention provides a method for testing power distribution of system. Firstly, it separately runs the compressed software for CPU, hard disk, memory and graphics, and separately records the actual consumption of peak current by using specialized test equipment, and then it calculates the actual maximum power consumption of each component. Secondly, it runs the software at the same time, and records their actual value in the current consumption, and calculates the overall actual maximum of power consumption. In the end, it combines the two records in power and a appropriate margin to reach a power supply option.
Description
Technical field
The present invention relates to the computer system field tests, the method for testing that specifically provides a kind of system power to distribute.
Background technology
At present, the selection foundation for performance number mainly contains two kinds when carrying out the power supply type selecting.
The one, fully the simple stack of the peak power of each parts in the system is selected.This value is on the basis with the power-handling capability addition of each parts, adds that certain allowance draws again.This yes insurance, but in actual applications, the situation that the power of each parts all reaches ratings simultaneously is absolutely not generation, also has certain allowance still more! So, can increase unnecessary production cost to product according to this superposition value fully, especially more can bring the waste of a large amount of production costs, and improve user's the cost that has for the bigger server power supply of power.
The 2nd, fully according to the recommended value among the System Power budget Roadmap of Intel.This suggestion numerical value is divided by radical sign 2 income values on the basis of first method.Because when system works, the state of each parts is different in the system, and some parts work is frequent (as processor) relatively, then fewer use (as the floppy drive) of some parts, therefore introduced a coefficient, rule of thumb normally add and the basis on divided by with numbers 2.This mode is the method that generally adopts at present, it greatly reduces cost than first kind of selection mode, but experiment showed, that this value is still excessive with respect to the actual consumption of system power, promptly with regard to present power is selected, still there is bigger cost waste.
Summary of the invention
The method of testing that a kind of system power of the present invention distributes is to propose at the inaccurate present situation that system power under the prior art is tested.It is based upon on the various concrete application foundations (as database, Web application, FTP, VOD video request program, recreation etc.), be used for the test macro power division, so that practicality power supply required according to reality and power supply manufacturer joint development high performance-price ratio, the actual power consumption that this method can precision measuring system simultaneously, and with this reliable basis as the power type selecting.
It is as follows that the method for testing that a kind of system power of the present invention distributes overcomes the above problems the technical scheme that is adopted:
The method of testing that a kind of system power distributes may further comprise the steps:
The pressurization software of A, difference central processor in service, hard disk, internal memory, network, video card;
B, write down the peak point current of each parts institute actual consumption respectively, and calculate the maximal value of the actual power consumption of each parts;
C, the pressurization software of above-mentioned parts is moved together, write down the maximal value of their overall actual consumption electric currents, calculate overall actual power consumption maximal value.
The step of the peak point current of each parts actual consumption of described measurement specifically comprises following;
For central processing unit:
A, all DC voltage of measuring mainboard CPU connecting line interface with current clamp be+voltage of the power supply output line of 12V, and write down greatest measure;
For the parts of extrapolation mainboard such as internal memory, video card:
A, measure the voltage on all on all connecting lines+12V power supply output line on the mainboard with current clamp, and the record greatest measure;
B, measure the voltage on all on all connecting lines+5V power supply output line on the mainboard with current clamp, and the record greatest measure;
C, measure the voltage on all on all connecting lines+3.3V power supply output line on the mainboard with current clamp, and the record greatest measure.
For hard disk:
A, with current clamp measure on the hard disk connecting line all+12V and+voltage on the 5V line, and record greatest measure.
The method of testing that a kind of system power of the present invention distributes, according to various application demands, move the pressurization software of CPU, hard disk, internal memory, network, video card at first respectively, and write down the peak point current of each parts institute actual consumption respectively with special testing apparatus, calculate the maximal value of the actual power consumption of each parts afterwards respectively; Pressurization software with above-mentioned parts moves together then, writes down the maximal value of their overall actual consumption electric currents, calculates overall actual power consumption maximal value.Two groups of performance numbers in conjunction with record add suitable allowance, are the foundation value of selecting the power specification.The system power that draws with this method serves as to select according to making power supply, can effectively reduce production costs and the user have cost, gone on intensive road, when improving product competitiveness, will inevitably bring more material benefit for users by the actual consumption customization.
