Abstract
The invention provides a method for using an ordinary single power supply to realize the equivalent PMBUS function, which aims at reducing the realizing cost of the dynamic power node management (DPNM) of a server system. The system comprises hardware and software, wherein the hardware comprises the ordinary single power supply, a PMBUS card, a PMBUS interface and a server main board, wherein the PMBUS card is connected in series on an output wire of the ordinary single power supply and the server main board, circuits relevant with the PMBUS function in the power supply are separated out to be made into an independent universal PMBUS card, the independent universal PMBUS card can be communicated with the server main board through the PMBUS interface only through modifying the Firmware program of the independent universal PMBUS card, and the goal of being matched with different ordinary single power supplies to be equivalent to the PMBUS power supply can be realized.
Description
Technical field
The present invention relates to the computer power supply field, be specifically related to a kind of method of using ordinary single power supply to realize equivalent PMBUS function.
Background technology
In " saving energy and reduce the cost " agitation that sweeps recently, the energy consumption of server is existing to be alleviated, in every method that cuts down the consumption of energy that industry is released, what attract attention the most is " dynamic power consumption node administration " (being DPNM) technology that Intel advocates, utilize this technology, can set some strategies, the dynamic power consumption of server is controlled within limits.And, just need change mainboard, operating system, BIOS and power supply for reaching this purpose, wherein one is exactly to require power supply to have PMBUS function (the PMBUS power supply of often saying just), can provide the power input data to server system.
Because the PMBUS power supply can provide the power input data to server system, so it is more complicated than common power, and many is the circuit such as energy consumption collection, communication of core with the control chip, and corresponding bottom software, i.e. Firmware.This part circuit and software have correspondingly increased the cost of power supply, and therefore, the PMBUS power supply of now seeing on the market nearly all is a redundant power.This is because for power supply supplier: if consider to use on single supply, the cost ratio probably accounts for 10%--20% so; If use on redundant power, the cost ratio can drop to 5% even lower so.But for server system manufacturer and terminal user, they more are concerned about the realization cost that reduces it when promoting DPNM, therefore, adopt the PMBUS redundant power much more expensive than adopting the PMBUS single supply undoubtedly.
A kind of single supply is realized the method for PMBUS function, proceeds from the reality just, utilizes power supply main body circuit and the thought that PMBUS circuit (being the PMBUS card) separates, and has both realized the DPNM technology of lower cost, for the client has brought practical economic interests; Reach the effect of " it is single that a card is joined many (individual) " again, solved the difficult problem of the no PMBUS function of common single electricity, had huge using value.
Summary of the invention
The purpose of this invention is to provide a kind of method of using ordinary single power supply to realize equivalent PMBUS function.
The objective of the invention is to realize in the following manner, comprise hardware and software, wherein hardware comprises common but power supply, the PMBUS card, PMBUS interface and server are sponsored, the PMBUS card is serially connected in and connects common but on the output wire rod that power supply and server are sponsored, circuit relevant with the PMBUS function in the power supply is separated, make a PMBUS card that independence is general, as long as software is its Firmware program of modification, communicate by letter with server master board by the PMBUS interface, the different ordinary single power supply of just can realizing arranging in pairs or groups is equivalent to the PMBUS power supply.
The invention has the beneficial effects as follows: reduced the realization cost of server system DPNM technology, having solved ordinary single power supply does not have the difficult problem of PMBUS function yet, thereby has good using value.
Description of drawings
Accompanying drawing 1 is the electrical block diagram of single supply;
Embodiment
With reference to Figure of description to explaining below the work of the present invention.
As shown in the figure, single supply of the present invention is realized the method for PMBUS function, comprise hardware and software, hardware comprises common but power supply, the PMBUS card, PMBUS interface and server are sponsored, the PMBUS card is serially connected in and connects common but on the output wire rod that power supply and server are sponsored, circuit relevant with the PMBUS function in the power supply is separated, make a PMBUS card that independence is general, by revising its Firmware software program, to communicate by letter with server master board by the PMBUS interface, the different ordinary single power supply of can realizing arranging in pairs or groups is equivalent to the PMBUS power supply.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
Claims (1)
