Mhoro, Habr! Masvondo mashoma apfuura raive zuva raipisa, iro ratakakurukura mu "imba yekusvuta" yehurukuro yebasa. Maminitsi mashoma gare gare, nhaurirano nezvemamiriro ekunze yakashanduka kuita hurukuro nezve kutonhora masisitimu enzvimbo dzedata. Kune mateki, kunyanya vashandi veSelectel, izvi hazvishamise; isu tinogara tichitaura nezvenyaya dzakafanana.
Munguva yekukurukurirana, takasarudza kuburitsa chinyorwa nezve kutonhora masisitimu muSelectel data centers. Chinyorwa chanhasi chiri pamusoro pekutonhora kwemahara, tekinoroji inoshandiswa mune mbiri dzenzvimbo dzedu dzedata. Pazasi pekuchekwa pane nyaya yakadzama nezvemhinduro dzedu uye maitiro avo. Ruzivo rwehunyanzvi rwakagovaniswa nemukuru wedhipatimendi resevhisi yemhepo yekufefetera uye yekufefetera, Leonid Lupandin, uye munyori mukuru wehunyanzvi Nikolay Rubanov.
Kutonhodza masisitimu paSelectel
Heino tsananguro pfupi yekuti ndeapi masisitimu ekutonhodza atinoshandisa munzvimbo dzedu dzese. Tichaenderera mberi nekutonhora-mahara muchikamu chinotevera. Tine muMoscow, St. Petersburg uye nharaunda yeLeningrad. Mamiriro ekunze mumatunhu aya akasiyana, saka tinoshandisa masisitimu ekutonhodza akasiyana. Nenzira, muMoscow data center yaiwanzoita majee kuti avo vane basa rekutonhora vaiva nyanzvi dzine mazita Kholodilin uye Moroz. Zvakaitika netsaona, asi zvakadaro...
Heino rondedzero yeDCs ine inotonhorera sisitimu inoshandiswa:
- Berzarina - kusununguka-kutonhora.
- Ruva 1 - freon, yemhando yepamusoro maindasitiri air conditioners enzvimbo dzedata.
- Ruva 2 - chillers.
- Dubrovka 1 - chillers.
- Dubrovka 2 - freon, yemhando yepamusoro maindasitiri air conditioners enzvimbo dzedata.
- Dubrovka 3 - kusununguka-kutonhora.
Munzvimbo dzedu dze data, tinoedza kuchengetedza tembiricha yemhepo pamuganho wakaderera weyakakurudzirwa range. Zviri 23Β°C.
Nezve freecooling
Munzvimbo mbiri dzedata, Dubrovka 3 ΠΈ Berzarina, takaisa masystem ekutonhodza emahara, uye akasiyana.
Yemahara kutonhora sisitimu muDC Berzarina
Nheyo yekutanga yemahara ekutonhodza masisitimu ndiko kubviswa kwezvinopisa kupisa, kuitira kuti kutonhora kwemidziyo yemakomputa kuitike nekuda kwekuvhuvhuta nemhepo yemumugwagwa. Inocheneswa uchishandisa mafirita, mushure mezvo inopinda mukamuri yemuchina. Mumatsutso uye munguva yechando, mhepo inotonhora inoda "kunyoroveswa" nemhepo inodziya kuitira kuti tembiricha yemhepo inovhuvhuta pamusoro pemidziyo isingachinji. Muchirimo muMoscow neSt. Petersburg, kumwe kutonhora kunodiwa.
Inogadziriswa mhepo inoputika
Sei kutonhora kwemahara? Ehe, nekuti tekinoroji inoshanda yemidziyo yekutonhodza. Mahara ekutonhodza masisitimu anowanzo kuchipa kushanda pane ekare air-conditioned mafiriji masisitimu. Imwe mukana wekutonhora kwemahara ndeyekuti kutonhora masisitimu haana simba rakadaro rakaipa pane zvakatipoteredza semhepo inofefetera ine freon.
Yakananga yemahara yekutonhodza chirongwa ine aftercooling isina yakasimudzwa pasi
Chinhu chakakosha: kutonhora kwemahara kunoshandiswa munzvimbo dzedu dzedata pamwe chete nemashure-kutonhora masisitimu. Munguva yechando, hapana matambudziko nekutora kwekunze kwemhepo inotonhora - kunze kunotonhorera, dzimwe nguva kunyange kutonhora zvikuru, saka mamwe maitiro ekutonhora haafaniri kudiwa. Asi muzhizha tembiricha yemhepo inokwira. Kana tikashandisa kutonhora kwemahara kwemahara, tembiricha yemukati ingangoita 27 Β°C. Ngatikuyeuchidzei kuti tembiricha yaSelectel i23Β°C.
Munharaunda yeLeningrad, tembiricha yenguva refu yemazuva ese, kunyangwe muna Chikunguru, inenge 20Β°C. Uye zvese zvinenge zvakanaka, asi pane mamwe mazuva kunopisa zvakanyanya. Muna 2010, chinyorwa chekushisa che +37.8 Β° C chakanyorwa munharaunda. Tichifunga nezvemamiriro ezvinhu aya, haugone kuverengera kutonhora kwemahara - zuva rimwe chete rinopisa pagore rinopfuura zvakakwana kuti tembiricha iende kupfuura mwero.
Sezvo St. Petersburg neMoscow vari megacities nemhepo yakasvibiswa, tinoshandisa katatu kucheneswa kwemhepo patinoitora kubva mumugwagwa - mafirita eG4, G5 uye G7 mitemo. Imwe neimwe inotevera inosefa guruva kubva kune zvidiki nezvidiki zvikamu, kuitira kuti chinobuda chive chakachena mhepo yemuchadenga.
Mafirita emhepo
Dubrovka 3 uye Berzarina - kutonhora kwemahara, asi kwakasiyana
Nezvikonzero zvakati wandei, tinoshandisa akasiyana emahara ekutonhodza masisitimu munzvimbo idzi dzedata.
Dubrovka 3
Iyo yekutanga DC ine kutonhora kwemahara yaive Dubrovka 3. Inoshandisa yakananga yakasununguka kutonhora, inowedzerwa neABHM, inonwisa firiji muchina unoshanda pane gasi rechisikigo. Muchina uyu unoshandiswa sekuwedzera kutonhora kana kuchipisa kwezhizha.
Kutonhodza nzvimbo yedata uchishandisa chirongwa chemahara-yekutonhorera ine pasi yakasimudzwa
Iyi hybrid mhinduro yakaita kuti zvikwanise kuwana PUE ~ 1.25.
Sei ABM? Iyi igadziriro inoshanda inoshandisa mvura pane freon. ABHM ine zvishoma zvinokanganisa nharaunda.
Muchina weABHM unoshandisa gasi rechisikigo, rinopihwa kwairi nepombi, sesimba rinobva pamhepo. Munguva yechando, kana motokari isingadiwi, gasi rinogona kupiswa kuti ridzise iyo supercooled kunze kwemhepo. Zvakachipa zvikuru pane kushandisa magetsi.
Maonero eABHM
Pfungwa yekushandisa ABHM senge mushure mekutonhodza sisitimu ndeyemumwe wevashandi vedu, injinjiniya, akaona mhinduro yakafanana uye akakurudzira kuishandisa kuna Selectel. Isu takagadzira modhi, tikaiedza, tikawana mhedzisiro yakanaka uye takasarudza kuikwidza.
Muchina uyu wakatora rinenge gore nehafu kuvaka, pamwe chete neventilation system uye data center pachayo. Yakatangwa kushanda muna 2013. Iko kunenge kusina matambudziko nazvo, asi kuti ushande unofanirwa kuwedzera kudzidziswa. Chimwe chezvinhu zveABHM ndechekuti muchina unochengetedza mutsauko wekumanikidza mukati nekunze kwekamuri yeDC. Izvi zvinodiwa kuti uve nechokwadi chekuti mhepo inopisa inopukunyuka kuburikidza neiyo valve system.
Nekuda kwemusiyano wekumanikidza, hapana kana huruva mumhepo, nekuti inongobhururuka kunze, kunyangwe ichionekwa. Kudzvinyirira kwakanyanya kunosundira zvidimbu kunze.
Mari yekugadzira masisitimu inogona kunge yakakwira zvishoma pane yekutonhodza kwakajairika. Asi ABHM inokubvumira kuchengetedza nekuderedza kushandiswa kwemagetsi ekupisa mhepo nekuitonhodza.
Berzarina
Dhiagiramu yekuyerera kwemhepo mukati mekamuri yeseva
Kutonhora kwemahara neadiabatic mushure-kutonhora system inoshandiswa pano. Inoshandiswa muzhizha kana mhepo yanyanya kudziya, uye tembiricha iri pamusoro pe23Β°C. Izvi zvinowanzoitika muMoscow. Iyo yekushandisa musimboti weadiabatic system ndeyekutonhodza mhepo sezvainopfuura nepamasefa ane mvura. Fungidzira jira rakanyorova iro mvura inoputika, inotonhora jira uye iri pedo nemhepo. Aya ndiwo mashandisiro anoita adiabatic kutonhora system mu data center. Madonhwe madiki emvura anopfapfaidzwa munzira yekuyerera kwemhepo, izvo zvinoderedza tembiricha yemhepo.
Kushanda musimboti weadiabatic kutonhora
Vakasarudza kushandisa kutonhora kwemahara pano nekuti data center iri pauriri hwepamusoro hwechivako. Izvi zvinoreva kuti mhepo inopisa inobudiswa kunze pakarepo inokwira, uye haidziviriri mamwe masisitimu, sezvingaitika dai iyo DC yaive iri pasi pasi. Nekuda kweizvi, chiratidzo chePUE chiri ~ 1.20
Uriri pahwakavapo, takafara nekuti takawana mukana wekugadzira chero zvataida. Basa guru raive rekugadzira DC ine inoshanda uye isingadhure yekutonhodza system.
Kubatsira kweadiabatic kutonhora ndiko kupusa kweiyo system pachayo. Zviri nyore kudarika zvirongwa zvine air conditioners uye kunyange zviri nyore kupfuura ABHM, uye inokubvumira kuchengetedza simba, mari iyo ishoma. Nekudaro, inoda kunyatsotariswa kuti ive nechokwadi kuti haipere sezvakaita Facebook muna 2012. Zvadaro, nekuda kwezvinetso nekugadzirisa zvirongwa zvekushanda, gore rechokwadi rakaumbwa munzvimbo yedata uye yakatanga kunaya. .
Control panels
Sistimu iyi yave nemakore maviri ichishanda, panguva iyi takaona matambudziko madiki akati wandei atiri kugadzirisa nevagadziri. Asi izvi hazvisi kutyisa, nokuti munguva yedu zvakakosha kugara uchitsvaga chimwe chinhu chitsva, kwete kukanganwa kutarisa mhinduro dziripo.
Isu tiri kugara tichitsvaga mikana yekushandisa matekinoroji matsva. Imwe yacho midziyo inoshanda zvakajairwa patembiricha iri pamusoro pe23Β°. Zvichida tichataura pamusoro peizvi mune imwe yezvinyorwa zvenguva yemberi, apo basa racho rinosvika padanho rekupedzisira.
Kana iwe uchida kuziva ruzivo nezve mamwe masisitimu ekutonhora mumaDC edu, saka neruzivo rwese.
Bvunza mibvunzo mumhinduro, isu tichaedza kupindura akawanda sezvatinogona.
