電子插箱電源分配系統的設計

 由于IT設備日益小型(xing)化(hua)，機箱(xiang)內設備安裝的(de)(de)(de)密度不斷增加，以1臺7U的(de)(de)(de)刀片(pian)式服務(wu)器為例，1臺大約需要(yao)3kVA的(de)(de)(de)配(pei)(pei)電(dian)(dian)(dian)，而(er)1臺42U高的(de)(de)(de)機柜可能(neng)安裝多(duo)達8臺這樣(yang)的(de)(de)(de)服務(wu)器，其配(pei)(pei)電(dian)(dian)(dian)總需求(qiu)量將達到(dao)24kVA。電(dian)(dian)(dian)子(zi)插(cha)箱(xiang)如何應對(dui)(dui)電(dian)(dian)(dian)源密度的(de)(de)(de)上升?隨著電(dian)(dian)(dian)子(zi)插(cha)箱(xiang)內IT安裝趨(qu)勢(shi)的(de)(de)(de)日益顯著，電(dian)(dian)(dian)子(zi)插(cha)箱(xiang)能(neng)否發揮(hui)其應能(neng)，配(pei)(pei)電(dian)(dian)(dian)系(xi)(xi)(xi)統成(cheng)為關鍵環(huan)節。合理的(de)(de)(de)電(dian)(dian)(dian)源分(fen)配(pei)(pei)直(zhi)接(jie)關系(xi)(xi)(xi)到(dao)整(zheng)(zheng)個IT系(xi)(xi)(xi)統的(de)(de)(de)可用性(xing)，而(er)且是整(zheng)(zheng)個系(xi)(xi)(xi)統能(neng)否發揮(hui)其應能(neng)的(de)(de)(de)重要(yao)基礎環(huan)節，而(er)這也是過去被很多(duo)機房(fang)管理人員忽視的(de)(de)(de)問題。這就對(dui)(dui)電(dian)(dian)(dian)子(zi)插(cha)箱(xiang)內配(pei)(pei)電(dian)(dian)(dian)系(xi)(xi)(xi)統提出(chu)了嚴(yan)峻的(de)(de)(de)挑(tiao)戰(zhan)。與此同時，輸入(ru)、輸出(chu)端(duan)口的(de)(de)(de)增多(duo)，也對(dui)(dui)配(pei)(pei)電(dian)(dian)(dian)系(xi)(xi)(xi)統安裝的(de)(de)(de)性(xing)提出(chu)了很高的(de)(de)(de)要(yao)求(qiu)。再(zai)考慮到(dao)目前大多(duo)數(shu)服務(wu)器雙電(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)的(de)(de)(de)需求(qiu)，   使得機柜內電(dian)(dian)(dian)源分(fen)配(pei)(pei)越來越繁(fan)雜。
　　合理的電子插箱電(dian)(dian)(dian)源分(fen)配系(xi)統(tong)的(de)設(she)計，則(ze)應遵循(xun)以(yi)性(xing)(xing)(xing)設(she)計為核心，專門針對(dui)機柜系(xi)統(tong)設(she)計，與配電(dian)(dian)(dian)系(xi)統(tong)充分(fen)協調、無縫(feng)配合的(de)原則(ze)，同(tong)(tong)時(shi)(shi)要考慮安裝的(de)方(fang)便(bian)(bian)性(xing)(xing)(xing)，以(yi)及(ji)智(zhi)能(neng)化管理、適應性(xing)(xing)(xing)強、便(bian)(bian)于操作與維護(hu)等特點。電(dian)(dian)(dian)子插(cha)箱的(de)配電(dian)(dian)(dian)系(xi)統(tong)，應使電(dian)(dian)(dian)源   接(jie)近負(fu)載，以(yi)減少電(dian)(dian)(dian)源通路(lu)中的(de)故(gu)障點。同(tong)(tong)時(shi)(shi)應逐步(bu)實現(xian)負(fu)載電(dian)(dian)(dian)流的(de)本(ben)地及(ji)遠程(cheng)監控，以(yi)及(ji)電(dian)(dian)(dian)源分(fen)配的(de)遠程(cheng)控制，使電(dian)(dian)(dian)源分(fen)配管理納入(ru)機房整體(ti)的(de)智(zhi)能(neng)化管理體(ti)系(xi)中。
