Ubukrelekrele PDU, okanye i-PDU ehlakaniphile, yenza okungaphezulu nje kokusabalalisa amandla kwizixhobo ze-IT kwiziko ledatha.Iyakwazi nokubeka iliso, ukulawula nokulawula ukusetyenziswa kwamandla kwezixhobo ezininzi.Ubukrelekrele PDUukunika iingcali zeziko ledatha ukufikelela okukude kuthungelwano lwedatha kwixesha lokwenyani malunga neziseko zoncedo ezibalulekileyo, ukuqhuba ukuthathwa kwezigqibo ezinolwazi, ukuqinisekisa ukufumaneka okuphezulu kunye nokuhlangabezana neemfuno ezibalulekileyo zocikizeko.Ii-PDU ezihlakaniphile ziwela kwiindidi ezimbini: ukubeka iliso kunye nokutshintsha, kwaye uhlobo ngalunye lunokongeza iintlobo ezahlukeneyo zezakhono ezongezelelweyo ukwandisa ulwazi olubalulekileyo olunokubonelela ngesixhobo.Ezinye izinto eziphambili ziquka ukubeka iliso kwinqanaba lokuphuma, ukubeka iliso kokusingqongileyo, izilumkiso kunye nezilumkiso ezisekelwe kwimida echazwe ngumsebenzisi, kunye nokunye.Ezi mpawu zinciphisa ixesha lokuphumla kwaye ziza kunye nenkxaso exhaswa ngumenzi ukuhlangabezana nezivumelwano zomgangatho wenkonzo (SLAs).
Njengoko iindawo zamaziko edatha ziba namandla kwaye zinzima, imibutho emininzi yezoshishino ibeka uxinzelelo kubaphathi bamaziko edatha ukunyusa ukufumaneka ngelixa ukunciphisa iindleko kunye nokwandisa ukusebenza kakuhle.Ukuqaliswa kwesizukulwana esitsha se-high-density servers kunye nezixhobo zenethiwekhi kuye kwandise imfuno yee-racks eziphezulu kwaye zineemfuno eziphezulu zenkqubo yamandla yesibonelelo siphela.Nangona ingxinano yerekhi eqhelekileyo ngoku isengaphantsi kwe-10kW, ingxinano yeerack ye-15kW sele ibume obuqhelekileyo kumaziko amakhulu kakhulu edatha, kwaye amanye ade asondele kuma-25kW.Ukucwangciswa koxinzelelo oluphezulu kuphucula ukusebenza kunye nomthamo wegumbi lekhompyutheni, kodwa ngexesha elifanayo lifuna ukunikezelwa kwamandla okusebenzayo.Ngenxa yoko, ukusebenza kunye nokusebenza kwePDU ekrelekreleiye yabaluleka kakhulu ukusasaza ngokufanelekileyo amandla kunye nokusingatha utshintsho kumthamo weziko ledatha kunye noxinaniso.
Ubukrelekrele PDUinokwahlulwa ngakumbi ibe ziindidi zokubeka iliso kunye nokutshintsha.Kwisiseko sayo, i-PDU ibonelela ngokusasazwa kwamandla okuthembekileyo, ngelixa ngaphezuluPDU ekrelekreleyongeza izakhono zokubeka iliso ezikude, ulawulo lwamandla, kunye neqonga loyilo elijonge phambili.
I-PDU ebekwe esweni inokufumaneka kwi-rack okanye ukude, inika umbono obanzi wokusetyenziswa kwamandla ngelixa uqhubeka nokubonelela ngokusasazwa kwamandla okuthembekileyo kwizixhobo ezibalulekileyo ze-IT.I-PDU ebekwe esweni inikezela nge-PDU-level kunye ne-outlet-level-level yokukhupha iinketho zoqwalaselo olude, ukubonelela ngombono wegranular wosetyenziso lwamandla ukuya kumgangatho wesixhobo.Banikezela ngofikelelo olukhawulezayo kulwazi olubalulekileyo ukuvavanya iindlela zokusebenzisa amandla kunye neempawu zokulumkisa ukulumkisa abasebenzisi xa imida yamandla echazwe ngumsebenzisi isophulwa.Kucetyiswa kumaziko edatha afuna ukubeka iliso okanye ukuphucula ukusetyenziswa kwamandla okusebenza (PUE).
I-PDU etshintshiweyo inokufumaneka kwi-rack okanye ukude, ibonelela ngembono ebanzi yokusetyenziswa kwamandla abalulekileyo kwisixhobo se-IT kunye nokongeza amandla okucima ukude, ukucima okanye ukuqalisa ngokutsha indawo nganye.I-PDU etshintshiweyo inikezela nge-PDU-level kunye ne-outlet-level-level yokukhupha iinketho zoqwalaselo olude.I-PDU etshintshiweyo ifanelekile kumaziko edatha kunye namaziko edatha akude apho ukusetyenziswa kwamandla okuphuma kufuneka kuncitshiswe ukuphepha ukugqithiswa ngengozi.Kwaye kumaziko edatha afuna ukukhawuleza kunye nokulula izixhobo zomjikelezo wamandla ngaphakathi kwendawo enkulu (kwaye ngamanye amaxesha inethiwekhi yonke yezibonelelo), i-PDU etshintshiweyo iluncedo.
Xa ukhetha iPDU ekrelekrele, qwalasela ezi mpawu ziphambili zilandelayo:
IP aggregation
Iidilesi ze-IP kunye nokutshintsha izibuko ziba zibiza kakhulu, ngoko ke abaphathi beziko ledatha banokunciphisa iindleko zokuthumelaPDU ekrelekrelengokusebenzisa iiyunithi ezinobuchule bokuhlanganisa i-IP.Ukuba iindleko zokuthumela ziyinkxalabo, kubalulekile ukuphanda ezinye iimfuno zokunciphisa umda zomenzi, njengoko inani leeseli ezinokudityaniswa kwidilesi ye-IP enye linokwahluka ukusuka ku-2 ukuya ku-50. -uqwalaselo, lunokunciphisa kakhulu ixesha lokuthunyelwa kunye neendleko.
Ukuhlolwa kokusingqongileyo
Izixhobo ze-IT zichaphazeleka kwiimeko zokusingqongileyo ezifana nobushushu kunye nokufuma.Ubukrelekrele PDUinokudibanisa i-sensor yendalo ukuze ibeke iliso ngenkuthalo iimeko zokusingqongileyo ngaphakathi kwe-rack, iqinisekisa iimeko ezifanelekileyo zokusebenza ngaphandle kokubeka isisombululo esahlukileyo sokubeka iliso.
unxibelelwano olungaphandle kwebhendi
Enye i-PDU ibonelela ngonxibelelwano olungafunekiyo ngokudibanisa nezixhobo zolawulo ezingaphandle kwebhendi ezifana nee-serial consoles okanye iiswitshi ze-KVM ukuba inethiwekhi ephambili yePDU iyasilela.
Ufikelelo lweDCIM
Kukho izisombululo ezahlukeneyo ze-DCIM kwimarike ezibonelela abasebenzisi indawo yokufikelela enye ukujonga amandla exesha lokwenyani kunye neenkcukacha zokusingqongileyo.I-DCIM ikwanakho ukwenza nokufumana iingxelo zohlalutyo lwentsingiselo, ibonelela ngokubonakala kuyo yonke indawo, inceda abaphathi bamaziko edatha ukuba baphucule ukusebenza kakuhle kunye nokufumaneka.
UQhagamshelwano olukude
Ubukrelekrele PDUikwabonelela ngabaphathi bamaziko edatha ngokukwazi ukufikelela bekude kwi-PDU ngokusebenzisa ujongano lwenethiwekhi okanye uqhagamshelo lwe-serial ukujonga ukusetyenziswa kwamandla kunye nokuqwalasela izaziso ezichazwe ngumsebenzisi ukunqanda ixesha lokuphumla.
