Moni, Habr! Masabata angapo apitawo linali tsiku lotentha, lomwe tinakambirana mu "chipinda chosuta" cha macheza a ntchito. Patangopita mphindi zochepa, kukambirana za nyengo kunasanduka kukambirana za machitidwe ozizira a malo opangira deta. Kwa techies, makamaka ogwira ntchito ku Selectel, izi sizodabwitsa; timangolankhula za mitu yofananira.
Pakukambilana, tidaganiza zofalitsa nkhani yokhudza kuziziritsa m'malo a data a Selectel. Nkhani yamasiku ano ikunena za kuziziritsa kwaulere, ukadaulo womwe umagwiritsidwa ntchito m'malo athu awiri a data. Pansi pa odulidwawo pali nkhani yatsatanetsatane ya mayankho athu ndi mawonekedwe ake. Zambiri zaukadaulo zidagawidwa ndi wamkulu wa dipatimenti yopereka zowongolera mpweya ndi mpweya wabwino, Leonid Lupandin, ndi wolemba wamkulu waukadaulo Nikolay Rubanov.
Makina ozizira ku Selectel
Nawa kufotokozera mwachidule za njira zoziziritsira zomwe timagwiritsa ntchito m'malo athu onse. Tipitilira kuzizilitsa mwaulere mu gawo lotsatira. Tili ndi ku Moscow, St. Petersburg ndi dera la Leningrad. Nyengo m'maderawa ndi yosiyana, choncho timagwiritsa ntchito njira zosiyanasiyana zozizira. Mwa njira, mu Moscow Data Center nthawi zambiri anali gwero nthabwala, amene udindo kuzirala anali akatswiri ndi mayina Kholodilin ndi Moroz. Zinachitika mwangozi, komabe ...
Nawu mndandanda wa ma DC omwe ali ndi makina ozizira omwe amagwiritsidwa ntchito:
- Berzarina - kuziziritsa kwaulere.
- Maluwa 1 - freon, zozizira zamafakitale zapamwamba zama data center.
- Maluwa 2 - ozizira.
- Dubrovka 1 - ozizira.
- Dubrovka 2 - freon, zozizira zamafakitale zapamwamba zama data center.
- Dubrovka 3 - kuziziritsa kwaulere.
M'malo athu a deta, timayesetsa kusunga kutentha kwa mpweya pamlingo wapansi wa zomwe zikulimbikitsidwa osiyanasiyana. Ndi 23Β°C.
Za freecooling
M'ma data centers awiri, Dubrovka 3 ΠΈ Berzarina, tinayika makina ozizirira aulere, ndi ena osiyanasiyana.
Makina ozizira aulere ku DC Berzarina
Mfundo yaikulu ya machitidwe oziziritsa aulere ndi kuthetsa kutentha kwa kutentha, kotero kuti kuzizira kwa zipangizo zamakompyuta kumachitika chifukwa cha kuwomba ndi mpweya wa mumsewu. Imatsukidwa pogwiritsa ntchito zosefera, kenako imalowa m'chipinda cha makina. M'dzinja ndi m'nyengo yozizira, mpweya wozizira umafunika "kusungunuka" ndi mpweya wofunda kuti kutentha kwa mpweya umene umawomba pazidawo usasinthe. M'chilimwe ku Moscow ndi St. Petersburg, kuzizira kwina kumafunika.
Ma air flaps osinthika
Chifukwa kuzirala kwaulere? Inde, chifukwa ndi teknoloji yothandiza pazida zozizirira. Makina ozizirira aulere nthawi zambiri amakhala otsika mtengo kuposa mafiriji akale a air-conditioned. Ubwino wina wa kuziziritsa kwaufulu ndikuti makina ozizirira alibe mphamvu yowononga chilengedwe monga ma air conditioners okhala ndi freon.
Chiwongolero chachindunji chozizirira chaulere chokhala ndi kuzizira komaliza popanda kukweza pansi
Mfundo yofunika: kuzirala kwaulere kumagwiritsidwa ntchito m'malo athu a data pamodzi ndi makina oziziritsa. M'nyengo yozizira, palibe mavuto ndi kulowetsedwa kwa mpweya wozizira wakunja - kumakhala kozizira kunja, nthawi zina ngakhale kuzizira kwambiri, kotero kuti njira zowonjezera zowonjezera sizifunikira. Koma mβchilimwe kutentha kwa mpweya kumakwera. Ngati titagwiritsa ntchito kuziziritsa kwaulere, kutentha mkati kukanakhala pafupifupi 27 Β°C. Tikukumbutseni kuti kutentha kwa Selectel ndi 23 Β° C.
M'chigawo cha Leningrad, kutentha kwanthawi yayitali tsiku lililonse, ngakhale mu Julayi, kumakhala pafupifupi 20 Β° C. Ndipo zonse zikhala bwino, koma masiku ena kumatentha kwambiri. Mu 2010, kutentha kwa +37.8 Β° C kunalembedwa m'deralo. Poganizira izi, simungadalire kuziziritsa kwaulere - tsiku limodzi lotentha pachaka ndilokwanira kuti kutentha kupitilira muyezo.
Popeza St. Petersburg ndi Moscow ndi megacities ndi mpweya woipitsidwa, timagwiritsa ntchito katatu kuyeretsa mpweya pamene tikutenga izo kuchokera mumsewu - zosefera za G4, G5 ndi G7 miyezo. Aliyense wotsatira amasefa fumbi kuchokera ku tizigawo ting'onoting'ono ndi tating'ono, kotero kuti linanena bungwe ndi mpweya wabwino wa mumlengalenga.
Zosefera mpweya
Dubrovka 3 ndi Berzarina - kuzirala kwaulere, koma kosiyana
Pazifukwa zingapo, timagwiritsa ntchito njira zosiyanasiyana zoziziritsira zaulere m'malo a data awa.
Dubrovka 3
DC yoyamba yokhala ndi kuzizira kwaufulu inali Dubrovka 3. Imagwiritsa ntchito kuzizira kwachindunji kwaulere, kuwonjezeredwa ndi ABHM, makina a firiji oyamwa omwe amayendetsa gasi. Makinawa amagwiritsidwa ntchito ngati kuzirala kowonjezera ngati kutentha kwachilimwe.
Kuziziritsa malo a data pogwiritsa ntchito dongosolo lozizira laulere ndi malo okwera
Njira yosakanizidwa iyi idapangitsa kuti zitheke kukwaniritsa PUE ~ 1.25.
Chifukwa chiyani ABHM? Iyi ndi njira yothandiza yomwe imagwiritsa ntchito madzi m'malo mwa freon. ABHM ili ndi mphamvu zochepa pa chilengedwe.
Monga gwero lamphamvu, makina a ABHM amagwiritsa ntchito gasi wachilengedwe, womwe umaperekedwa kwa iwo ndi payipi. M'nyengo yozizira, pamene galimoto sikufunika, gasi akhoza kuwotchedwa kutentha supercooled kunja mpweya. Ndiotsika mtengo kuposa kugwiritsa ntchito magetsi.
Chithunzi cha ABHM
Lingaliro logwiritsa ntchito ABHM ngati makina oziziritsa pambuyo pozizira ndi la m'modzi mwa antchito athu, mainjiniya, yemwe adawona yankho lofananalo ndipo adati agwiritse ntchito kwa Selectel. Tinapanga chitsanzo, kuchiyesa, tidapeza zotsatira zabwino kwambiri ndipo tinaganiza zochikulitsa.
Makinawa adatenga pafupifupi chaka ndi theka kuti amange, limodzi ndi makina opangira mpweya wabwino komanso malo opangira data. Idakhazikitsidwa mu 2013. Palibe zovuta nazo, koma kuti mugwire ntchito muyenera kuphunzitsidwa zina. Chimodzi mwa zinthu za ABHM ndikuti makinawa amasunga kusiyana kwapakati mkati ndi kunja kwa chipinda cha DC. Izi ndi zofunika kuonetsetsa kuti mpweya wotentha umatuluka kudzera mu valve.
Chifukwa cha kusiyana kwamphamvu, palibe fumbi mumlengalenga, chifukwa limangowuluka, ngakhale likuwoneka. Kupanikizika kwambiri kumakankhira particles kunja.
Ndalama zokonzetsera makina zitha kukhala zokwera pang'ono kuposa zoziziritsa wamba. Koma ABHM imakupatsani mwayi wopulumutsa pochepetsa kugwiritsa ntchito magetsi pakuwotcha mpweya ndikuziziritsa.
Berzarina
Chithunzi cha kayendedwe ka mpweya mkati mwa chipinda cha seva
Kuziziritsa kwaulele ndi adiabatic pambuyo-kuzizira kumagwiritsidwa ntchito pano. Amagwiritsidwa ntchito m'chilimwe pamene mpweya umakhala wofunda kwambiri, ndipo kutentha kumakhala pamwamba pa 23 Β° C. Izi zimachitika nthawi zambiri ku Moscow. Mfundo yoyendetsera dongosolo la adiabatic ndikuziziritsa mpweya pamene ukudutsa muzosefera zomwe zili ndi madzi. Tangoganizani chiguduli chonyowa chomwe madzi amatuluka, kuziziritsa nsalu ndi mpweya woyandikana nawo. Umu ndi momwe pulogalamu yozizira ya adiabatic imagwirira ntchito mu data center. Tidontho ting'onoting'ono tamadzi timawathira m'njira ya mpweya, zomwe zimachepetsa kutentha kwa mpweya.
Mfundo yogwira ntchito ya kuzizira kwa adiabatic
Anaganiza zogwiritsa ntchito kuzirala kwaulere pano chifukwa malo osungiramo data ali pamwamba pa nyumbayo. Izi zikutanthauza kuti mpweya wotentha womwe umatuluka kunja nthawi yomweyo umapita mmwamba, ndipo suletsa machitidwe ena, monga momwe zingathere ngati DC inali pansi pamunsi. Chifukwa cha izi, chizindikiro cha PUE ndi ~ 1.20
Malo amenewa atapezeka, tinali osangalala chifukwa tinali ndi mwayi wopanga chilichonse chimene tinkafuna. Ntchito yayikulu inali kupanga DC yokhala ndi njira yabwino komanso yotsika mtengo yozizirira.
Ubwino wa kuzizira kwa adiabatic ndi kuphweka kwa dongosolo lokha. Ndizosavuta kuposa machitidwe okhala ndi mpweya komanso ngakhale zosavuta kuposa ABHM, ndipo zimakulolani kusunga mphamvu, zomwe mtengo wake ndi wochepa. Komabe, ikuyenera kuyang'aniridwa mosamala kuti zitsimikizire kuti sizikutha monga momwe Facebook idachitira mu 2012. Kenako, chifukwa cha zovuta pakukhazikitsa magawo ogwiritsira ntchito, mtambo weniweni udapangidwa mu data center ndipo idayamba kugwa mvula. .
Control panels
Dongosololi lakhala likugwira ntchito kwa zaka ziwiri zokha, panthawi yomwe tazindikira zovuta zingapo zazing'ono zomwe tikukumana nazo ndi opanga. Koma izi sizowopsya, chifukwa m'nthawi yathu ndikofunika kuti nthawi zonse muzifufuza zatsopano, osaiwala kuyang'ana njira zomwe zilipo.
Nthawi zonse timayang'ana mipata yogwiritsira ntchito matekinoloje atsopano. Chimodzi mwa izo ndi zipangizo zomwe zimagwira ntchito bwino pa kutentha pamwamba pa 23 Β°. Mwina tidzakambirana za izi m'nkhani zina zamtsogolo, pamene polojekiti ikufika kumapeto.
Ngati mukufuna kudziwa zambiri zamakina ena ozizira mu ma DC athu, ndiye ndi chidziwitso chonse.
Funsani mafunso mu ndemanga, tidzayesetsa kuyankha momwe tingathere.
