Ib qho ntawm cov virtualization racks. Peb tau txais tsis meej pem nrog cov xim qhia txog cov cables: txiv kab ntxwv txhais tau tias khib fais fab, ntsuab txhais tau tias txawm.
Ntawm no peb feem ntau tham txog "cov cuab yeej loj" - chillers, diesel generator sets, main switchboards. Niaj hnub no peb yuav tham txog "cov khoom me me" - cov khoom siv hauv racks, tseem hu ua Power Distribution Unit (PDU). Peb cov chaw zov me nyuam muaj ntau tshaj 4 txhiab racks uas muaj cov cuab yeej siv IT, yog li kuv pom ntau yam hauv kev ua: classic PDUs, "ntse" nrog kev saib xyuas thiab kev tswj hwm, cov qhov (socket) zoo tib yam. Hnub no kuv yuav qhia koj tias PDUs muaj dab tsi thiab qhov zoo dua los xaiv hauv ib qho xwm txheej.
Dab tsi ntawm PDUs muaj?
Yooj yim socket thaiv. Yog lawm, ib yam uas nyob hauv txhua lub tsev lossis chaw ua haujlwm.
Raws li txoj cai, qhov no tsis yog raws nraim PDU hauv kev nkag siab ntawm kev lag luam siv hauv cov khoom siv IT, tab sis cov cuab yeej no kuj muaj lawv cov kiv cua. Qhov zoo ntawm cov tshuaj no tsuas yog nws tus nqi qis (tus nqi pib ntawm 2 txhiab rubles). Lawv kuj tuaj yeem pab tau yog tias koj siv cov racks qhib, qhov twg koj tsis tuaj yeem haum tus qauv PDU, thiab koj tsis xav kom poob chav nyob hauv qab PDU kab rov tav. Qhov no rov qab los rau lo lus nug ntawm kev txuag.
Muaj ntau qhov tsis zoo: cov khoom siv zoo li no tsis tas yuav muaj kev tiv thaiv sab hauv los tiv thaiv luv luv Circuit Court thiab overloads, koj tsis tuaj yeem saib xyuas cov ntsuas, thiab ntau dua yog li koj yuav tsis muaj peev xwm tswj tau cov sockets. Feem ntau lawv yuav nyob rau hauv qab ntawm lub khib. Qhov no tsis yog qhov yooj yim tshaj plaws txoj hauj lwm ntawm lub qhov (socket) rau disconnecting khoom.
Feem ntau, "pilots" tuaj yeem siv tau yog tias:
- koj muaj ntau txhiab tus servers thiab koj yuav tsum tau txuag nyiaj,
- koj tuaj yeem them nyiaj rau qhov muag tsis pom kev txuas cov khoom siv, tsis nkag siab qhov tshwm sim nrog kev noj tiag tiag,
- npaj rau cov khoom siv downtime.
Peb tsis siv qhov no, tab sis peb muaj cov neeg siv khoom uas siv nws zoo heev. Muaj tseeb, lawv tsim cov txheej txheem rau lawv cov kev pabcuam hauv txoj hauv kev uas tsis ua haujlwm ntawm ntau lub servers tsis cuam tshuam rau kev ua haujlwm ntawm cov neeg siv khoom thov.
Pheej yig thiab zoo siab.
Kev tso chaw ntsug.
"Dumb" PDUs. Qhov tseeb, qhov no yog PDU classic rau siv hauv racks nrog IT khoom, thiab qhov ntawd yog qhov zoo. Lawv muaj cov qauv tsim nyog rau kev tso kawm ntawm ob sab ntawm lub khib, ua kom yooj yim rau kev txuas cov khoom siv rau lawv. Muaj kev tiv thaiv sab hauv. Xws li PDUs tsis muaj kev saib xyuas, uas txhais tau tias peb yuav tsis paub tias cov khoom siv twg siv ntau npaum li cas, thiab qhov tshwm sim tiag tiag hauv. Peb yuav luag tsis muaj PDUs li ntawd, thiab feem ntau lawv maj mam ploj mus los ntawm kev siv loj.
Xws li PDUs raug nqi los ntawm 25 txhiab rubles.
"Smart" PDUs nrog kev saib xyuas. Cov khoom siv no muaj "lub hlwb" thiab lawv tuaj yeem saib xyuas kev siv hluav taws xob. Muaj cov zaub uas cov cim tseem ceeb tau tshwm sim: voltage, tam sim no thiab lub zog. Koj tuaj yeem taug qab lawv los ntawm ib pawg ntawm cov chaw muag khoom: ntu lossis tsev txhab nyiaj. Koj tuaj yeem txuas mus rau PDU qhov chaw deb thiab teeb tsa kev xa cov ntaub ntawv mus rau qhov kev saib xyuas. Lawv sau cov cav uas koj tuaj yeem pom txhua yam uas tshwm sim rau nws, piv txwv li, thaum lub PDU raug kaw.
Lawv kuj tuaj yeem suav cov kev siv (kWh) rau kev suav nyiaj kom nkag siab ntau npaum li cas cov khib nyiab siv rau qee lub sijhawm.
Cov no yog cov qauv PDUs uas peb muab rau peb cov neeg siv khoom xauj tsev, thiab cov no yog feem ntau ntawm PDUs hauv peb cov ntaub ntawv chaw.
Yog hais tias koj yuav, npaj txhij mus rau lub plhaub tawm 75 txhiab rubles ib thooj.
Daim duab los ntawm peb qhov kev soj ntsuam PDU.
"Smart" PDUs nrog kev tswj hwm. Cov PDUs no ntxiv kev tswj hwm rau cov txuj ci tau piav qhia saum toj no. Qhov txias tshaj PDUs tswj thiab saib xyuas txhua qhov hluav taws xob: koj tuaj yeem tig nws rau / tawm, uas yog qee zaum tsim nyog nyob rau hauv cov xwm txheej uas txoj haujlwm yog kom rov pib dua lub server vim lub zog. Qhov no yog ob qho tib si kev zoo nkauj thiab qhov txaus ntshai ntawm xws li PDUs: tus neeg siv zoo tib yam, tsis paub txog, tuaj yeem nkag mus rau hauv lub vev xaib interface, nyem ib yam dab tsi thiab hauv ib qho poob swoop reboot / tua tag nrho cov kab ke. Yog lawm, lub kaw lus yuav ceeb toom koj ob zaug txog qhov tshwm sim, tab sis kev xyaum qhia tau hais tias txawm tias lub tswb nrov tsis tas yuav tiv thaiv cov neeg siv ua pob liab liab.
Ib qho teeb meem loj nrog PDUs ntse yog overheating thiab tsis ua hauj lwm ntawm tus maub los thiab zaub. PDUs feem ntau yog ntsia rau tom qab ntawm lub khib, qhov twg cov cua kub tau tshuab tawm. Nws kub nyob ntawd thiab cov tswj tsis tuaj yeem tuav nws. Hauv qhov no, PDU tsis tas yuav hloov pauv tag nrho; tus maub los tuaj yeem hloov pauv kub.
Zoo, tus nqi yog heev ntxhab - los ntawm 120 txhiab rubles.
Kev tswj PDU tuaj yeem txheeb xyuas los ntawm qhov qhia hauv qab txhua lub qhov (socket).
Hauv kuv lub tswv yim, kev tswj hwm kev ua haujlwm hauv PDU yog qhov teeb meem ntawm saj, tab sis kev saib xyuas yog qhov yuav tsum muaj. Txwv tsis pub, nws yuav tsis yooj yim sua kom taug qab noj thiab thauj khoom. Kuv yuav qhia koj tias vim li cas qhov no tseem ceeb me ntsis tom qab.
Yuav ua li cas xam lub zog PDU?
Thaum xub thawj siab ib muag, txhua yam ntawm no yog qhov yooj yim heev: lub zog ntawm PDU raug xaiv raws li lub zog ntawm lub khib, tab sis muaj nuances. Cia peb hais tias koj xav tau 10 kW khib. PDU manufacturers muab cov qauv rau 3, 7, 11, 22 kW. Xaiv 11 kW, thiab, hmoov tsis, koj yuav yuam kev. Peb yuav tau xaiv 22 kW. Vim li cas peb thiaj xav tau cov khoom siv loj li no? Kuv mam piav txhua yam tam sim no.
Ua ntej, cov tuam ntxhab feem ntau qhia PDU lub zog hauv kilowatts ntau dua li kilovolt-amperes, uas yog qhov tseeb dua, tab sis tsis pom tseeb rau tus neeg nruab nrab.
Qee lub sij hawm manufacturers lawv tus kheej tsim kev tsis meej pem ntxiv:
Ntawm no lawv thawj zaug tham txog 11 kW,
Thiab hauv cov lus piav qhia ntxaws peb tab tom tham txog 11000 VA:
Yog tias koj tab tom ua haujlwm nrog cov kav dej thiab cov neeg siv khoom zoo sib xws, ces yuav tsis muaj qhov sib txawv ntawm kW thiab kVA. 10 kW khib nrog kettles yuav siv 10 kVA. Tab sis yog tias peb muaj cov khoom siv IT, ces tus coefficient (cos Ο) tshwm nyob rau ntawd: cov khoom siv tshiab, qhov ze dua qhov coefficient yog rau ib qho. Lub tsev kho mob nruab nrab rau cov khoom siv IT tuaj yeem yog 0,93β0,95. Yog li ntawd, 10 kW khib nrog IT yuav siv 10,7 kVA. Ntawm no yog cov qauv uas peb tau txais 10,7 kVA.
Ptotal = Pact./Cos(Ο)
10/0.93 = 10.7 kVA
Zoo, koj yuav nug cov lus nug tsim nyog: 10,7 tsawg dua 11. Vim li cas peb thiaj xav tau 22 kW chaw taws teeb tswj? Muaj qhov taw tes thib ob: theem ntawm kev siv hluav taws xob ntawm cov khoom siv yuav txawv nyob ntawm lub sijhawm ntawm hnub thiab hnub ntawm lub lim tiam. Thaum faib hluav taws xob, koj yuav tsum tau coj lub sijhawm no mus rau hauv tus account thiab khaws cia ~ 10% rau qhov hloov pauv thiab nce siab, yog li thaum noj nce ntxiv, PDUs tsis mus rau hauv cov khoom siv ntau dhau thiab tawm hauv cov khoom tsis muaj zog.
Daim duab ntawm kev noj cov khib nyiab ntawm 10 kW rau 4 hnub.
Nws hloov tawm tias peb yuav tsum ntxiv 10,7% ntxiv rau 10 kW peb muaj, thiab vim li ntawd, 11 kW chaw taws teeb tswj tsis haum rau peb lawm.

Installation Nta
Nws yog qhov yooj yim tshaj plaws los ua haujlwm nrog PDU thaum nws yog mounted vertically, mus rau sab laug thiab sab xis ntawm lub khib. Hauv qhov no, nws tsis siv qhov chaw muaj txiaj ntsig. Standardly, mus txog plaub PDUs tuaj yeem ntsia tau rau hauv khib - ob sab laug thiab ob sab xis. Feem ntau, ib qho PDU muab tso rau ntawm txhua sab. Txhua PDU tau txais ib lub zog tawm tswv yim.
Tus qauv "cov khoom siv lub cev" ntawm lub khib yog 2 PDUs thiab 1 ATS.
Qee lub sij hawm tsis muaj chaw nyob hauv khib rau ntsug PDUs, piv txwv li yog tias nws yog qhov qhib khib. Tom qab ntawd kab rov tav PDUs tuaj cawm. Qhov tsuas yog qhov no koj yuav tsum lees txais qhov poob ntawm 2 mus rau 4 units hauv khib, nyob ntawm tus qauv PDU.
Ntawm no PDU noj 4 units. Hom PDU no kuj tseem siv tau thaum nws tsim nyog los sib txawv ntawm ob tus neeg siv khoom hauv tib lub khib. Hauv qhov no, txhua tus neeg siv khoom yuav muaj ib khub ntawm PDUs.
Nws tshwm sim tias khib xaiv tsis sib sib zog nqus txaus, thiab cov neeg rau zaub mov tawm, thaiv PDU. Qhov kev tu siab tshaj plaws ntawm no tsis yog qee qhov ntawm lub qhov (socket) yuav tsis ua haujlwm, tab sis yog tias PDU tawg, koj yuav tsum muab faus rau hauv lub khib, lossis tua thiab tshem tawm tag nrho cov khoom cuam tshuam.
Tsis txhob ua qhov no - 1.
Tsis txhob ua qhov no - 2.
Cov khoom sib txuas
Txawm tias PDU sophisticated feem ntau yuav tsis pab yog tias cov cuab yeej txuas nrog tsis raug thiab tsis muaj txoj hauv kev los saib xyuas kev noj.
Yuav ua li cas mus tsis ncaj ncees lawm? Me ntsis . Txhua lub khib nyiab muaj ob lub zog nkag; ib lub khib nyiab muaj ob lub PDUs. Nws hloov tawm tias txhua PDU muaj nws tus kheej cov tswv yim. Yog tias muaj qee yam tshwm sim rau ib qho ntawm cov khoom siv (nyeem PDU), cov khib nyiab tseem nyob ntawm qhov thib ob. Txhawm rau kom cov txheej txheem no ua haujlwm, koj yuav tsum ua raws qee cov cai. Ntawm no yog cov tseem ceeb (koj tuaj yeem pom daim ntawv teev npe tag nrho ):
Cov khoom siv yuav tsum txuas nrog PDUs sib txawv. Yog tias cov cuab yeej muaj ib lub hwj chim thiab ib lub ntsaws, ces nws txuas nrog PDU ntawm ATS (tsis siv neeg hloov pauv hloov) lossis ATS (Tsis Siv Neeg Hloov Hloov Hloov). Thaum muaj teeb meem nrog ib qho ntawm cov khoom siv lossis PDU nws tus kheej, ATS hloov cov cuab yeej mus rau kev noj qab haus huv PDU / tawm tswv yim. Cov cuab yeej yuav tsis hnov ββdab tsi.
Paired load ntawm ob lub tswv yim / PDU. Cov tswv yim thaub qab yuav txuag tau tsuas yog tias nws tuaj yeem tiv taus lub nra ntawm cov lus tawm poob. Txhawm rau ua qhov no, koj yuav tsum tau tawm ntawm qhov cia: thauj khoom txhua qhov kev tawm tswv yim tsawg dua ib nrab ntawm lub zog ntsuas, thiab tag nrho cov khoom thauj ntawm ob qhov khoom siv tsawg dua 100% ntawm lub npe. Tsuas yog nyob rau hauv cov ntaub ntawv no tus ntxiv input yuav tiv tau ob npaug rau load. Yog tias qhov no tsis yog rau koj, ces qhov ua kom yuam kev ntawm kev hloov mus rau qhov tshwj tseg yuav tsis ua haujlwm - cov khoom siv yuav nyob twj ywm tsis muaj zog. Txhawm rau tiv thaiv qhov tsis zoo tshwm sim, peb qhov ntsuas no.
Load sib npaug ntawm PDU seem. PDU sockets tau muab tso ua ke rau hauv pawg - ntu. Feem ntau 2 lossis 3 daim. Txhua ntu muaj nws lub zog txwv. Nws yog ib qho tseem ceeb tsis txhob tshaj nws thiab faib cov khoom sib npaug ntawm txhua ntu. Zoo, zaj dab neeg nrog kev sib koom ua ke, uas tau tham saum toj no, kuj ua haujlwm ntawm no.
Cia kuv piav qhia
- Yog tias ua tau, xaiv PDU nrog kev saib xyuas kev ua haujlwm.
- Thaum xaiv PDU qauv, cia qee lub zog cia.
- Mount lub PDU kom nws tuaj yeem hloov pauv yam tsis cuam tshuam koj cov khoom siv IT.
- Txuas kom raug: txuas cov khoom siv rau ob lub PDUs, tsis txhob overload seem thiab paub txog cov khoom ua ke.
