中型數(shu)據中心(xin)的(de)基礎設(she)(she)施系統主要(yao)分(fen)電(dian)源、環境控制和機房監(jian)控管理系統。由(you)于(yu)中型數(shu)據中心(xin)承載企業(ye)、機構的(de)核心(xin)業(ye)務，重要(yao)性較高。因而中型數(shu)據中心(xin)一般根(gen)據TIA942標準的(de)Tier4和Tier3標準建設(she)(she)，可靠(kao)性要(yao)求99.999%以(yi)上，以(yi)保(bao)證(zheng)大部分(fen)異常故障和正(zheng)常維護情況(kuang)下(xia)，數(shu)據中心(xin)正(zheng)常工(gong)作，核心(xin)業(ye)務不受(shou)影(ying)響。

　 1、電(dian)(dian)(dian)(dian)源(yuan)系統(tong)，通常選用(yong)多路市電(dian)(dian)(dian)(dian)源(yuan)互為備(bei)份，并且機(ji)房設有(you)專用(yong)柴油發電(dian)(dian)(dian)(dian)機(ji)系統(tong)作為備(bei)用(yong)電(dian)(dian)(dian)(dian)源(yuan)系統(tong)，市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)間(jian)、市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)和柴油發電(dian)(dian)(dian)(dian)機(ji)間(jian)通過(guo)ATS（自(zi)動切(qie)換(huan)開關）進(jin)行切(qie)換(huan)，為數據中心內UPS（不(bu)間(jian)斷供(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)）、機(ji)房空(kong)調(diao)、照明等設備(bei)供(gong)電(dian)(dian)(dian)(dian)。

　 由于中(zhong)型數(shu)(shu)據中(zhong)心(xin)業務(wu)(wu)重要(yao)性，通常(chang)采用(yong)雙母(mu)(mu)(mu)線(xian)或冗余(yu)并(bing)機(ji)的(de)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)方(fang)案供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)，滿(man)足中(zhong)型數(shu)(shu)據中(zhong)心(xin)服務(wu)(wu)器等IT設(she)備高可靠性用(yong)電(dian)(dian)(dian)要(yao)求(qiu)。雙母(mu)(mu)(mu)線(xian)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)系統(tong)(tong)，有兩套(tao)獨立UPS供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)系統(tong)(tong)（包(bao)含(han)UPS配(pei)電(dian)(dian)(dian)系統(tong)(tong)），在(zai)任一套(tao)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)母(mu)(mu)(mu)線(xian)（供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)系統(tong)(tong)）需要(yao)維護或故(gu)障等無(wu)法正(zheng)常(chang)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)的(de)情況下，另一套(tao)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)母(mu)(mu)(mu)線(xian)仍能承擔所有負載，保證(zheng)機(ji)房業務(wu)(wu)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)，確保數(shu)(shu)據中(zhong)心(xin)業務(wu)(wu)不受影響。冗余(yu)并(bing)機(ji)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)系統(tong)(tong)，采用(yong)UPS冗余(yu)并(bing)機(ji)的(de)方(fang)式，提(ti)高供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)系統(tong)(tong)的(de)可靠性，保證(zheng)數(shu)(shu)據中(zhong)心(xin)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)。

　 在(zai)UPS輸出到(dao)服務器(qi)等(deng)IT設(she)(she)備(bei)輸入間，選(xuan)(xuan)用(yong)SPM（服務器(qi)電(dian)(dian)(dian)(dian)源(yuan)(yuan)管(guan)理(li)器(qi)）進行(xing)電(dian)(dian)(dian)(dian)源(yuan)(yuan)分(fen)配(pei)和供(gong)(gong)電(dian)(dian)(dian)(dian)管(guan)理(li)，實現對每(mei)臺機柜(ju)用(yong)電(dian)(dian)(dian)(dian)監控管(guan)理(li)，提(ti)高供(gong)(gong)電(dian)(dian)(dian)(dian)系(xi)(xi)統的(de)可(ke)靠(kao)性和易(yi)管(guan)理(li)性。對于雙路電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)服務器(qi)等(deng)IT設(she)(she)備(bei)，可(ke)以通過(guo)SPM直(zhi)接從雙母(mu)線供(gong)(gong)電(dian)(dian)(dian)(dian)系(xi)(xi)統的(de)兩(liang)套(tao)(tao)母(mu)線引人電(dian)(dian)(dian)(dian)源(yuan)(yuan)，即可(ke)保證其(qi)用(yong)電(dian)(dian)(dian)(dian)高可(ke)靠(kao)性。對于單路電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)服務器(qi)等(deng)IT設(she)(she)備(bei)，通常選(xuan)(xuan)用(yong)STS（靜態切換(huan)開關）為其(qi)選(xuan)(xuan)擇切換(huan)一套(tao)(tao)供(gong)(gong)電(dian)(dian)(dian)(dian)母(mu)線供(gong)(gong)電(dian)(dian)(dian)(dian)。在(zai)供(gong)(gong)電(dian)(dian)(dian)(dian)母(mu)線無法正常供(gong)(gong)電(dian)(dian)(dian)(dian)時，STS將自動快(kuai)速切換(huan)到(dao)另(ling)一套(tao)(tao)供(gong)(gong)電(dian)(dian)(dian)(dian)正常的(de)母(mu)線供(gong)(gong)電(dian)(dian)(dian)(dian)，確保服務器(qi)等(deng)IT設(she)(she)備(bei)的(de)可(ke)靠(kao)用(yong)電(dian)(dian)(dian)(dian)。
