Abstract
The invention discloses a method for designing an external card supplying power to a server mainboard memory. A traditional onboard memory VR power supply module is extracted to be made into an independent memory VR power supply daughter card, and then the daughter card is connected with a mainboard through a connector. By means of the method, space of the mainboard is effectively saved, expansion capability of sixteen dual in-line memory modules (DIMMs) and expansion capability of more peripheral component interface express (PCIE) and input and output (IO) modules can be achieved within limited space, mainboard memory VR power supply lines are simplified, layout of other devices of the mainboard is facilitated, and the memory VR design is modularized. If power supply lines of some memory are damaged, a new external card can be directly replaced without scrapping the whole mainboard, and accordingly, maintainability and maintenance efficiency of a board card are improved. The memory VR power supply daughter card is positioned higher than the mainboard and parallel to the DIMMs, cooling of power devices is facilitated under the condition of the same speed of a fan, and efficiency of a VR conversion module is improved.

Technical field
The present invention relates to the server master board field, be specifically related to a kind of outer plug-in card method for designing of server master board internal memory power supply.
Technical background
Be accompanied by the continuous rise of cloud computing technology, the fast development of Internet enterprises, and the operational line amount constantly increases.Large-Scale Interconnected net enterprise has higher requirement to data-handling capacity, the internal memory extended capability of machine room server.General large-scale data center machine room, no matter rent or self-built, its cost is all very expensive.How in the finite space, to increase in veneer CPU quantity, raising the extended capability that can deposit extended capability, improve PCIE slot and IO functional module, to server and Rack product, all stronger competitive power can be arranged.
At present, in the Rack rack, the node that uses mostly is the 1U server master board, is mainly two kinds of standard motherboard and half-breadth mainboards.The standard template is easy to realize the extended capability of two CPU and 16 DIMM, generally not there will be the problem of components and parts without space arrangement; And can there be the difficult problem of part components and parts without space arrangement in the half-breadth mainboard because being limited to the mainboard overall dimensions if realize the extended capability of two CPU and 16 DIMM.
Prior art internal memory VR module board carries method for designing as shown in Figure 1, and because the mainboard width only can be put 8 internal memories and 1 CPU base, internal memory VR modular converter can't be placed in centre, internal memory VR module can only be positioned over to the two ends of DIMM groove.This layout type waste mainboard large tracts of land useful space, make PCIE and IO extended capability diminish.
Summary of the invention
The technical problem to be solved in the present invention is: because being limited to the mainboard overall dimensions, have the difficult problem of part components and parts without space arrangement.
The technical solution adopted in the present invention is: a kind of outer plug-in card method for designing of server master board internal memory power supply, and traditional plate is carried to internal memory VR supply module and extract, make independently internal memory VR power supply subcard, then by Connector, subcard is connected with mainboard.Can effectively optimize the mainboard device layout, large tracts of land is saved the mainboard finite space.
A kind of server master board, comprise two CPU, article 16, DIMM and 2 CPU VR modules, two CPU are positioned at mainboard left part center section, 2 CPU VR modules lay respectively in the middle of two CPU, article 16, DIMM is divided into 4 groups of positions, both sides that are positioned at respectively each CPU of mainboard left part, wherein also comprises 4 Connector, lays respectively between every group of DIMM and CPU.
A kind of internal memory VR power supply subcard, comprise the VR control chip, LC filter inductance and the electric capacity that connect to arrange successively from the board right-hand member, two-phase DrMOS, outputting inductance, output terminal filter capacitor, the Connector be connected with mainboard left, wherein the overcurrent capability of the Pin pin of Connector should meet the maximum current design requirement of internal memory.
Wherein the VR control chip adopts IR digital power controller IR3570A, and DrMOS selects the IR3550 of IR.
Beneficial effect of the present invention is:
(1) can effectively save the mainboard space, make and realize 16 DIMM extended capabilities and more PCIE and IO module extended capability in the finite space;
(2) mainboard internal memory VR supply line is simplified, also be beneficial to the Layout cabling of other device of mainboard;
(3) internal memory VR designs modularization more.If, after the supply line of certain group internal memory breaks down, the outer plug-in card that can directly more renew gets final product, and needn't scrap the monoblock mainboard, thereby has improved maintainability and the maintenance efficiency of board;
(4) internal memory VR power supply subcard can exceed mainboard, and the direction parallel with DIMM placement, in the situation that the identical fans rotating speed more is conducive to the heat radiation of Power device, improves the efficiency of VR modular converter.
