Data Center Heat Load Testing Thiab Vim Li Cas Transformers tseem ceeb tshaj qhov koj xav

Thaum tib neeg tham txog niaj hnubcov chaw zov me nyuam, lawv feem ntau dhia ncaj nraim rau lub tshuab cua txias lossis tej zaum cov servers. Tab sis qhov tseeb,data center heat load testingyog hais txog tag nrho cov saw hlau ua haujlwm ua ke- tsis yog sab IT flashy xwb.

Thiab ntawm no yog qee yam uas feem ntau tau underestimated:transformers. Lawv tsis yog "cov khoom siv fais fab hauv qab." Lawv ntsiag to ua kom sov npaum li cas lub chaw ua haujlwm tiag tiag yuav tsum tau nrog.

Hu rau tam sim no

Nyob rau theem pib,data center heat load testingtsuas yog sim teb cov lus nug uas siv tau:

Lub chaw puas tuaj yeem tshem tawm tag nrho cov cua sov thaum txhua yam khiav ntawm qhov qaij?

Vim hais tias yuav luag txhua watt ntawm hluav taws xob mus rau hauv IT cov cuab yeej xaus li cua sov. Yog li thaum kuaj, engineers pib tshawb xyuas seb:

 Cov tshuab cua txias tuaj yeem khaws cia

 Airflow coj raws li qhov xav tau

 Cov chaw kub tsis pib popping hauv racks

 Lub kaw lus tseem tuav tau thaum thauj khoom nce

Nws yog ib feem simulation, qhov kev ntsuam xyuas kev ntxhov siab, thiab ua siab ncaj, me ntsis ntawm "cia saib dab tsi tawg ua ntej."

Ntau tus neeg tsis tuaj yeem txuas tam sim ntawd transformers nrog cua sov loadkuaj, tab sis lawv yuav tsum.

Hauv kev teeb tsa ib txwm:

Kev siv hluav taws xob →Hloov pauv → UPS → PDU→ Servers

Txhua kauj ruam ntawm txoj kev ntxiv me ntsis poob. Thiab transformers yog ib tug ntawm cov loj contributors rau qhov ntawd.

Lawv tsim cov cua sov feem ntau los ntawm:

 Toojpoob (uas nce thaum load nce)

 Corepoob (ib txwm nyob ntawd, txawm tias thaum tsis ua haujlwm)

Yog li ntawd, txawm tias ua ntej cov servers pib ua txhua yam "pab tau", transformers twb tau ntxiv cua sov rau hauv lub cev.

Ntawm no yog ib qho yooj yim tawg ntawm qhov twg tshav kub los ntawm lub sij hawmdata center heat load testing:

 Qhov tseem ceeb ntawm kev tshem tawm: transformers zaum hauv nruab nrab theem ntawm cov khoom siv hluav taws xob- tsis yog qhov loj tshaj, tab sis nws yeej tsis tsim nyog.

Thaum lub load nce thaum lub sij hawmdata center heat load testing, transformers tsis yog zaum ntsiag to. Ob peb yam pib tshwm sim:

Lawv ua cua sov

Ntau tam sim no txhais tau tias ntau dua I²R poob. Yooj yim physics, tab sis nws ntxiv ceev. Windings tau sov, tom qab ntawd kub dua, thiab cov kws ua haujlwm saib xyuas qhov kev txwv ntawm rwb thaiv tsev.

Harmonics ua rau nws tsis zoo

Niaj hnub IT loads-tshwj xeeb yog GPUs thiab hloov- hom khoom siv hluav taws xob- tsis yog "huv." Lawv qhia txog harmonics, thiab cov zaus ntxiv:

 Ua kom poob

 Ntxiv cua sov ntxiv

 Ua kom transformers ua hauj lwm nyuaj tshaj li lub npe daim ntawv qhia

Tias yog vim li cas koj feem ntau yuav pom:

K- ntsuas transformers

Harmonic mitigating designs

Lawv yeej nyob ntawd kom muaj sia nyob zoo li hluav taws xob tsis zoo.

Nov yog qhov nthuav dav uas tau txais tsis nco qab xav tsis thoob ntau zaus:

Transformers lawv tus kheej yog ib feem ntawm lub tshav kub load.

Lawv tsis yog hla lub zog xwb. Lawv nquag tso cua sov rau hauv ib puag ncig.

Piv txwv li, lub nruab nrab transformer yuav ntsiag to tso tej yam zoo li 10-20 kW ntawm tshav kub. Qhov ntawd tsis yog me me. Thiab twv seb nws mus qhov twg?

Txoj cai rau hauv lub tshuab cua txias cov npe ua haujlwm.

Yog li thaumdata center heat load testing, nws tsis yog servers uas koj xav txog xwb. Nws yog:

 IT load

 UPS poob

 Fais fab faib losses

 Transformer cua sov

Tag nrho nws stacks.

Tsis yog txhua tus transformers coj tib txoj hauv kev hauv ib puag ncig cov ntaub ntawv.

Qhuav- hom transformers

Cov no yog cov nyob hauv tsev. Lawv:

Tso cua sov ncaj qha rau hauv chav hluav taws xob

Ua kom HVAC xav tau

Ua kom chav- theem cua txias tsim tseem ceeb dua li cov neeg xav tau

Pad-mounted transformers Pad-mounted transformer

Cov no zaum sab nraum lub tsev, yog li:

Thaum tshav kub kub tsis ncaj qha mus rau hauv cov ntaub ntawv chav

Tab sis lawv tseem cuam tshuam rau kev ua haujlwm ntawm lub cev thiab kev coj tus cwj pwm ntawm cov dej ntws

Kev tso kawm sib txawv, sib txawv thermal cuam tshuam.

AI hloov qhov kev ua si me ntsis.

Peb tham:

 GPU racks ntom heev (20-100 kW txhua, qee zaum ntau dua)

 Siab dua tam sim no ntws los ntawm transformers

 Ntau harmonic distortion

 Tsawg thermal margin tag nrho

Yog li ntawd mam li nco dheev,data center heat load testingtsis yog hais txog "peb puas tuaj yeem txias chav?"

Nws yuav zoo li:

 Puas yog tag nrho lub zog hluav taws xob muaj sia nyob tag nrho yam tsis muaj cua sov?

 Puas yog peb underestimating thaum tshav kub kub qhov chaw xws li transformers?

 Thiab feem ntau, cov lus teb xav tau kev saib thib ob.

Thaum kawg ntawm hnub,data center heat load testingyog tiag tiag txog kev nkag siab tag nrho lub zog- rau- cov saw kub kub - tsis yog cov servers xwb.

Transformers zaum hauv nruab nrab ntawm cov saw hlau ntawd. Lawv tsis cia li xa hwj chim; lawv kuj ntsiag to ua rau cov cua sov uas lub tshuab cua txias yuav tsum tshem tawm.

Thaum koj pib saib nws li ntawd, tag nrho cov duab thermal ua qhov tseeb ntau dua -thiab me ntsis "huv" dua li daim duab qhia.
