Imwe yemukati virtualization racks. Isu takavhiringika nechiratidzo chemavara chetambo: orenji zvinoreva odd simba rekuisa, girinhi zvinoreva kunyange.
Pano isu tinowanzo taura nezve "michina mikuru" - chiller, dizeli jenareta seti, main switchboards. Nhasi tichataura nezve "zvinhu zvidiki" - zvigadziko mumaracks, anozivikanwawo sePower Distribution Unit (PDU). Nzvimbo dzedu dzedata dzine anopfuura zviuru zvina racks dzakazadzwa nemidziyo yeIT, saka ndakaona zvinhu zvakawanda mukuita: maPDU emhando yepamusoro, "akangwara" ane kutarisa uye kutonga, akajairwa socket block. Nhasi ndichakuudza kuti maPDU aripo uye chii chiri nani kusarudza mune imwe mamiriro ezvinhu.
Ndeapi marudzi ePDU aripo?
Nyore socket block. Hongu, imwe cheteyo inogara mumusha wega wega kana hofisi.
Pakare, iyi haisi iyo chaiyo PDU mupfungwa yekushandiswa kwemaindasitiri mumaraki ane IT michina, asi zvishandiso izvi zvakare zvine vateveri vazvo. Kubatsira chete kwemhinduro iyi ndiyo yakaderera mutengo (mutengo unotanga kubva ku2 zviuru rubles). Vanogonawo kubatsira kana iwe ukashandisa akavhurika racks, kwausingakwanise kukwana PDU yakajairwa, uye iwe haudi kurasikirwa nemayunitsi pasi pePDU yakatwasuka. Izvi zvinodzoka kumubvunzo wekuchengetedza.
Pane zvakawanda zvisingabatsiri: zvishandiso zvakadaro hazvigaro zvidziviriro zvemukati kubva kumaseketi mapfupi uye zvakawandisa, haugone kutarisa zviratidzo, uye zvakanyanya saka haugone kudzora zvigadziko. Kazhinji kazhinji ivo vanozove vari pazasi pe rack. Iyi haisi iyo yakanyanya nyore chinzvimbo chezvigadziko zvekubvisa michina.
Kazhinji, "vatyairi" vanogona kushandiswa kana:
- une zviuru zvemaseva uye unofanirwa kuchengetedza mari,
- iwe unokwanisa kukwanisa kubatanidza michina neupofu, usinganzwisise zviri kuitika nekushandisa chaiko,
- akagadzirira midziyo downtime.
Isu hatishandise izvi, asi isu tine vatengi vanozviita zvinobudirira. Ichokwadi, ivo vanovaka zvivakwa zvemasevhisi avo nenzira yekuti kutadza kwemasevha mazhinji hakukanganise kuita kwemutengi application.
Cheap uye anofara.
Vertical placement.
"Nyama" PDUs. Chaizvoizvo, iyi yakajairika PDU yekushandisa mumaraki ane IT michina, uye izvo zvatonaka. Ivo vane fomu rakakodzera rekuisa pamativi eraki, zvichiita kuti zvive nyore kubatanidza michina kwavari. Pane kudzivirira mukati. MaPDU akadaro haana kutarisa, izvo zvinoreva kuti hatizoziva kuti ndezvipi zvinoshandiswa zvinodya yakawanda sei, uye chii chiri kuitika mukati. Isu tine dzinenge dzisina maPDU akadaro asara, uye kazhinji ari kunyangarika zvishoma nezvishoma kubva mukushandiswa kukuru.
PDU dzakadaro dzinodhura kubva ku25 zviuru rubles.
"Smart" PDUs nekutarisa. Midziyo iyi ine "brains" uye inogona kutarisa mashandisirwo emagetsi paramita. Pane kuratidzwa uko zviratidzo zvikuru zvinoratidzwa: voltage, ikozvino uye simba. Unogona kuvatevera nemapoka ega ezvitoro: zvikamu kana mabhangi. Iwe unogona kubatana kune yakadaro PDU kure uye kugadzirisa kutumira data kune yekutarisa system. Ivo vanonyora matanda kubva kwaunogona kuona zvese zvakaitika kwairi, semuenzaniso, apo chaizvo iyo PDU yakadzima.
Ivo vanogona zvakare kuverenga kushandiswa (kWh) kwehunyanzvi accounting kuitira kuti unzwisise kuti yakawanda sei rack inopedza mune imwe nguva yenguva.
Aya ndiwo maPDU akajairwa atinopa kune vatengi vedu kurenda, uye aya ndiwo mazhinji ePDU munzvimbo dzedu dzedata.
Kana iwe ukatenga, gadzirira kuburitsa zviuru makumi manomwe nezvishanu zveRubles imwe neimwe.
Girafu kubva kune yedu yemukati PDU yekutarisa.
"Smart" PDUs ine kutonga. Aya maPDU anowedzera manejimendi kune hunyanzvi hwakatsanangurwa pamusoro. Iyo inotonhorera PDUs inodzora uye yekutarisa imwe neimwe yekubuda: unogona kuibatidza / kudzima, izvo dzimwe nguva zvinodikanwa mumamiriro ezvinhu apo basa nderekutanga kure kure sevha nekuda kwesimba. Uku ndiko kunaka uye nengozi yemaPDU akadaro: mushandisi akajairwa, asingazivi, anogona kupinda muwebhu interface, tinya chimwe chinhu uye mune imwe yakadonha swoop reboot / kudzima iyo yese system. Hongu, iyo sisitimu ichakuyambira kaviri nezvemhedzisiro, asi maitiro anoratidza kuti kunyangwe maaramu haagare achidzivirira kubva kune anomhanyisa mushandisi zviito.
Dambudziko hombe ne smart PDUs kupisa uye kutadza kwemutongi uye kuratidza. PDUs inowanzoiswa kuseri kwerack, uko mhepo inopisa inoputika. Kuri kupisa ikoko uye vatongi havagoni kuzvibata. Muchiitiko ichi, iyo PDU haidi kushandurwa zvachose; iyo controller inogona kuchinjwa inopisa.
Zvakanaka, mutengo wakanyanya kukwira - kubva ku120 zviuru rubles.
Iyo yekudzora PDU inogona kuzivikanwa nechiratidzo pasi pega yega socket.
Mukuona kwangu, basa rekutonga muPDU inyaya yekuravira, asi kutarisa kunofanirwa kuve nako. Zvikasadaro, hazvizogoneke kuteedzera kushandiswa uye kurodha. Ini ndichakuudza kuti nei izvi zvakakosha zvishoma gare gare.
Maitiro ekuverenga iyo inodiwa PDU simba?
Pakutanga kuona, zvese pano zviri nyore: simba rePDU rinosarudzwa zvinoenderana nesimba reiyo rack, asi pane nuances. Ngatiti iwe unoda rack 10 kW. Vagadziri vePDU vanopa mhando dze3, 7, 11, 22 kW. Sarudza 11 kW, uye, zvinosuruvarisa, iwe unenge usina kururama. Tichafanira kusarudza 22 kW. Nei tichida mugove wakakura kudaro? Ndichatsanangura zvose zvino.
Chekutanga, vagadziri vanowanzo ratidza simba rePDU mu kilowatts pane kilovolt-amperes, izvo zviri zvakanyanya, asi zvisingaonekwe kune avhareji munhu.
Dzimwe nguva vanogadzira ivo pachavo vanogadzira imwe nyonganiso:
Pano vanotanga kutaura nezve 11 kW,
Uye mune yakadzama tsananguro tiri kutaura nezve 11000 VA:
Kana uri kutarisana nekettles nevatengi vakafanana, ipapo hapazovi nemusiyano pakati pe kW ne kVA. Raka re10 kW rine kettles rinopedza 10 kVA. Asi kana tine michina yeIT, ipapo coefficient (cos Ο) inooneka ipapo: iyo itsva midziyo, iyo inoswedera pedyo iyi coefficient kune imwe. Avhareji yechipatara yemidziyo yeIT inogona kuva 0,93β0,95. Naizvozvo, rack ye10 kW ine IT ichapedza 10,7 kVA. Heino fomula yatakawana nayo 10,7 kVA.
Ptotal= Pact./Cos(Ο)
10/0.93=10.7 kVA
Zvakanaka, iwe uchabvunza mubvunzo unonzwisisika: 10,7 isingasviki 11. Sei tichida 22 kW remote control? Pane imwe pfungwa yechipiri: chiyero chekushandiswa kwesimba kwemidziyo ichasiyana zvichienderana nenguva yezuva uye zuva revhiki. Paunenge uchigovera simba, iwe unofanirwa kutora nguva ino muaccount uye kuchengetedza ~ 10% yekuchinja uye surges, kuitira kuti kana kushandiswa kunowedzera, maPDU asapinda mukuremerwa uye kusiya michina isina simba.
Girafu yekushandisa rack ye10 kW kwemazuva mana.
Zvinoitika kuti tinofanira kuwedzera imwe 10,7% kune 10 kW yatinayo, uye nekudaro, iyo 11 kW kure kure haichakodzeri isu.

Kugadzira Zvinhu
Izvo zvakanyanya nyore kushanda nePDU kana yakasimudzwa yakatwasuka, kuruboshwe uye kurudyi kweraki. Muchiitiko ichi, hazvitore chero nzvimbo inobatsira. Sezvineiwo, anosvika mana PDU anogona kuiswa murack - maviri kuruboshwe uye maviri kurudyi. Kazhinji, imwe PDU inoiswa kune rumwe rutivi. Imwe neimwe PDU inogamuchira imwe simba rekuisa.
Iyo yakajairwa "body kit" yeraki ndeye 2 PDUs uye 1 ATS.
Dzimwe nguva hapana nzvimbo muraki yePDU dzakamira, semuenzaniso kana iri rack yakashama. Ipapo maPDU akatwasuka anouya kuzonunura. Chinhu chimwe chete ndechekuti munyaya iyi uchafanirwa kubvuma kurasikirwa kwezvikamu zviviri kusvika ku2 mu rack, zvichienderana nemuenzaniso wePDU.
Apa PDU yakadya 4 units. Iyi mhando yePDU inoshandiswawo kana zvichidikanwa kusiyanisa pakati pevatengi vaviri mune imwechete rack. Muchiitiko ichi, mutengi wega wega achave neakasiyana maviri ePDU.
Izvo zvinoitika kuti rack yakasarudzwa haina kudzika zvakakwana, uye sevha inomira kunze, ichivharira iyo PDU. Chinhu chinosuruvarisa apa hachisi chekuti mamwe masokisi achange asina basa, asi kuti kana PDU yakadaro ikaputsika, iwe unofanirwa kuiviga musheti chaimo, kana kudzima uye kubvisa zvese zvinokanganisa midziyo.

Kubatanidza michina
Kunyangwe iyo yakanyanya kuomesesa PDU haibatsire kana michina yakabatana zvisizvo uye pasina nzira yekutarisa mashandisirwo.
Chii chinogona kukanganisa? Zvishoma . Imwe neimwe rack ine maviri emagetsi ekuisa; yakajairwa rack ine maviri PDUs. Zvinoitika kuti imwe neimwe PDU ine yayo yekuisa. Kana chimwe chinhu chikaitika kune imwe yezvipimo (verenga PDU), ipapo rack inoramba ichirarama pane yechipiri. Kuti chirongwa ichi chishande, unofanirwa kutevera mimwe mitemo. Heano iwo makuru (unogona kuwana runyorwa ruzere ):
Iyo midziyo inofanirwa kuve yakabatana kune akasiyana maPDU. Kana iyo midziyo iine simba rimwe chete uye plug imwe, saka yakabatana nePDU kuburikidza neATS (otomatiki yekuchinja switch) kana ATS (Otomatiki Transfer Switch). Kana paine matambudziko neimwe yekupinza kana iyo PDU pachayo, iyo ATS inochinjisa michina kune ine hutano PDU/input. Iyo midziyo haizonzwa chero chinhu.
Pair mutoro pane maviri ekuisa / PDU. Iyo backup yekuisa inochengetedza chete kana ichikwanisa kumira kuremerwa kweiyo yakadonha yekuisa. Kuti uite izvi, iwe unofanirwa kusiya chengetedzo: takura imwe neimwe yekuisa isingasviki hafu yesimba rakayerwa, uye iyo yakazara mutoro pane maviri ekuisa yaive isingasviki 100% yezita. Chete munyaya iyi iyo yakasara inopinza ichamira kaviri mutoro. Kana izvi zvisiri izvo kwauri, saka hunyengeri hwekuchinjira kune chengetedzo hauzoshande - michina icharamba isina simba. Kudzivirira zvakaipisisa kuti zvisaitike, isu iyi parameter.
Kuyera kuyera pakati pezvikamu zvePDU. PDU sockets inosanganiswa kuita mapoka - zvikamu. Kazhinji 2 kana 3 zvidimbu. Chikamu chimwe nechimwe chine muganhu wesimba rayo. Zvakakosha kuti usapfuure uye kugovera mutoro wakaenzana muzvikamu zvose. Zvakanaka, iyo nyaya ine mitoro yakapetwa, iyo yakakurukurwa pamusoro, inoshandawo pano.
Rega ndipfupise
- Kana zvichibvira, sarudza PDU ine monitoring performance.
- Paunosarudza modhi yePDU, siya mamwe masimba emagetsi.
- Mount iyo PDU kuitira kuti igone kutsiviwa pasina kukanganisa yako IT michina.
- Batanidza nemazvo: batanidza zvishandiso kune maviri maPDU, usaremedze zvikamu uye ziva nezvemitoro yakapetwa.
