Dab tsi yog Data Center PDU, thiab Vim Li Cas Nws Thiaj Li Xav Tau Kev Hloov Pauv?

Nyem qhov no kom paub ntau ntxiv txog yaweitransformer.

Yog koj twb tau xav li cascov chaw zov me nyuamkhaws ntau txhiab tus servers khiav tsis tu ncua, ib feem loj ntawm cov lus teb yog kev faib hluav taws xob. Thiab txoj cai nyob rau hauv nruab nrab ntawm tag nrho cov uas yog PDU- luv luv rau Fais Fais Fais Fab Chav. Nws tsis yog qhov zoo nkauj tshaj plaws ntawm cov iav, tab sis ntseeg kuv, tsis muaj dab tsi ua haujlwm yam tsis muaj nws.

Tab sis ntawm no yog qhov khoom: ntau PDUs kuj tuaj nrog lub tshuab hloov pauv hauv lawv. Thiab qhov ntawd tsis yog rau kev ua yeeb yam xwb. Cia peb tawg vim li cas.

Xav txog PDU ua qhov kawg nres ua ntej lub zog mus txog koj cov servers. Nws siv hluav taws xob los ntawm qhov chaw tseem ceeb (feem ntau tom qab nws tau ntxuav los ntawm UPS) thiab faib nws tawm mus rau tag nrho cov racks, lub thawv cia, thiab kev sib txuas sib txuas.

Qee qhov PDUs yog qhov yooj yim tiag tiag -tsuas yog qhov zoo nkauj lub hwj chim strips. Lwm tus yogntse: lawv tuaj yeem taug qab kev siv hluav taws xob, cia koj tig qhov hluav taws xob rau thiab tawm ntawm qhov chaw deb, thiab tseem xa cov lus ceeb toom yog tias muaj qee yam tawm.

Lub luag haujlwm tseem ceeb ntawm PDU:

Tau txais lub zog rau IT iav

Tiv thaiv hluav taws xob hiccups

Saib xyuas ntau npaum li cas cov kua txiv hmab txiv ntoo siv

Pab kom sib npaug ntawm cov load nyob hauv circuits

Ua kom tswj fais fab tsis mob taub hau

Yog tsis muaj kev teeb tsa PDU zoo, txhua yam yuav ntxhov sai. Koj yuav muaj cables nyob txhua qhov chaw thiab tsis muaj kev tswj xyuas qhov twg lub zog mus.

Nov yog txoj hauv kev ib txwm muaj zog siv los ntawm daim phiaj mus rau koj cov servers:

Utility Grid →Main Transformer→ Switchgear →UPS→ PDU → Server Racks

Txhua kauj ruam muaj lub luag haujlwm:

Hloov pauvhloov voltage theem nce lossis nqis

Switchgearcia koj tswj thiab tiv thaiv circuits

UPSua kom cov khoom khiav thaum muaj hluav taws xob

PDUmuab lub zog kawg rau cov khoom siv

Qhov txheej txheej txheej no txhais tau tias koj tuaj yeem poob ib qho thiab tseem nyob online. Zoo nkauj ntse, txoj cai?

Zoo lus nug. Tsis yog txhua tus PDU muaj ib qho, tab sis thaum lawv ua, feem ntau muaj qee qhov laj thawj.

1. Kev hloov hluav taws xob

Ntau lub teb chaws (thiab cov khoom siv sib txawv) nyiam qhov sib txawv voltages. APDU transformer tuaj yeem nqa, hais, 480V los ntawm qhov chaw thiab nqis mus rau 208V rau North American servers. Los yog 400V rau 230V nyob rau hauv lwm qhov chaw ntawm lub ntiaj teb no. Yog tsis muaj li ntawd, koj yuav kib koj cov iav los yog nws tsuas yog tsis tig rau.

2. Kev cais hluav taws xob

Qhov no yog ib tug loj. Ib qho kev sib cais transformer tsim kev sib cais ntawm lub zog tuaj thiab dab tsi mus rau koj cov servers. Uas pab nrog:

Txo cov suab nrov hluav taws xob (yog, qhov ntawd yog qhov tseeb)

Txhim kho annoying av voj teeb meem

Tiv thaiv cov khoom kim heev

Ua kom lub cev ruaj khov thaum muaj tej yam txawv txawv tshwm sim

Rau cov cuab yeej IT rhiab heev, qhov kev sib cais ntawd tuaj yeem yog tus cawm seej.

3. TamingHarmonics

Niaj hnub nimno cov chaw zov me nyuam muaj tag nrho cov khoom uas cuam tshuam nrog lub zog: servers, UPSs, hloov pauv ceev tsav, hloov cov khoom siv hluav taws xob. Tag nrho lawv tsim kev sib haum xeeb- feem ntau yog hluav taws xob distortion. Ntau dhau ntawm qhov ntawd, thiab tej yam overheat los yog poob thaum ntxov. Ib qho zoo PDU transformer tuaj yeem pab txhuam qee qhov tawm.

Thaum koj tso ib qho kev sib cais transformer nyob rau hauv PDU, koj tau txais ob peb cov txiaj ntsig zoo:

Kev ntseeg tau zoo dua- teeb meem hluav taws xob tsis dhia hla circuits yooj yim

Lub zog huv- Tsawg suab nrov thiab tsawg glitches me me

Kev ua haujlwm nyab xeeb dua- zoo dua tiv thaiv av weirdness

Tsawg downtime- Cov cuab yeej siv tau ntev dua thiab sib tsoo tsawg dua

Nws tsis yog khawv koob, tab sis nws ua rau qhov sib txawv tiag tiag.

Cia peb ua siab ncaj: downtime yog tus yeeb ncuab. Txawm ob peb vib nas this ntawm weirdlub hwj chim tuaj yeem raug nqi ntau txhiab - lossis phem dua, cuam tshuam cov neeg siv khoom.

Nov yog qhov zoo PDU transformer pab kom zam qhov ntawd:

Ua kom voltages tsis tu ncua

Thaiv kev cuam tshuam me me los ntawm kev ncav cuag servers

Ua haujlwm nrog kev teeb tsa tsis tu ncua kom ib qho tsis ua haujlwm tsis yog kev puas tsuaj

Pab cais cov txhaum kom lawv tsis txhob kis mus

Zuag qhia tag nrho, tsuas yog ua kom lub zog nqus dej thiab ua kom pom tseeb dua

Qhov ntawd yog ntau tus nqi los ntawm qhov zoo li lub thawv hlau hnyav.

Yog li cas engineers tiag tiag saib thaum xaiv ib qho? Ob peb yam:

Dab tsi voltage koj xav tau nyob rau hauv vs tawm?Lub hwj chim (kVA) yuav tsum tau ua li cas?Nws ua haujlwm npaum li cas? (Tsis muaj leej twg xav nkim zog)Nws puas tuaj yeem tuav harmonics yam tsis muaj overheating?Nws puas xav tau cov kiv cua, lossis tsuas yog cua txias xwb?Nws mus qhov twg? (Kub aisle? Cold aisle? Tight space?)

Niaj hnub no, feem ntau cov chaw zov me nyuam mus nrogqhuav - hom transformers. Lawv muaj kev nyab xeeb dua, tsis xav tau cov kua txias, thiab ua haujlwm zoo hauv tsev nrog tsawg fuss.

Lub chaw ntaub ntawv PDU yog txoj kev ntau dua li lub zog hluav taws xob. Nws yog tus choj tseem ceeb ntawm koj lub tsev hluav taws xob thiab txhua daim IT iav uas koj tso siab rau. Thiab thaum koj ntxiv ib lub qhov dej -xaiv transformer rau hauv qhov sib tov-tshwj xeeb yog ib hom kev sib cais- koj tau txais kev hloov pauv hluav taws xob, lub zog huv, kev nyab xeeb zoo dua, thiab tsawg dua kev poob siab.

Raws li cov chaw zov me nyuam loj hlob thiab ntim hauv ntau lub iav, qhov hloov pauv me me hauv PDU yuav muaj teeb meem ntau dua. Tsis txaus siab, tej zaum. Tab sis qhov tseem ceeb kiag li.
