Kufunika kwa Kuwunika Kutentha ndi Chinyezi pa Dongosolo la Data Center

Kwa zaka zambiri, pakhala kuwonjezeka kwakukulu kwa malo akuluakulu osungira deta omwe amakhala ndi makompyuta, ma seva osungira ma cloud computing, ndi zida zothandizira kulumikizana. Izi ndizofunikira kwambiri ku kampani iliyonse yomwe ikugwira ntchito za IT padziko lonse lapansi.

Kwa opanga zida za IT, mphamvu yowonjezereka ya makompyuta ndi luso lowongolera makompyuta ndizofunikira kwambiri. Chifukwa cha kuchuluka kwa malo osungira deta omwe amafunika kukhala ndi ma seva ambiri, akhala ogwiritsa ntchito mphamvu zofunika kwambiri. Onse okhudzidwa, kuphatikizapo opanga zida, opanga malo osungira deta, ndi ogwiritsa ntchito, akhala akugwira ntchito kuti achepetse kugwiritsa ntchito mphamvu kwa gawo la zida zosakhala za IT pa mphamvu yonse: mtengo waukulu ndi zomangamanga zoziziritsira zomwe zimathandizira zida za IT.

Chinyezi chochuluka kapena chochepa kwambiri chingapangitse anthu kukhala osasangalala. Mofananamo, zipangizo zamakompyuta sizikonda mikhalidwe yovutayi monga momwe ife timachitira. Chinyezi chochuluka chimapangitsa kuti madzi aziundana ndipo chinyezi chochepa chimapangitsa magetsi osasinthasintha: mikhalidwe yonseyi imatha kukhala ndi zotsatirapo zazikulu ndipo ingawononge makompyuta ndi zida zomwe zili mu data center.

Chifukwa chake, malo abwino okhala ndi chilengedwe ayenera kusamalidwa ndi kulamulidwa, ndipo chinyezi ndi kutentha ziyenera kuyezedwa molondola pogwiritsa ntchitozotumizira kutentha ndi chinyezikuti apititse patsogolo kugwiritsa ntchito mphamvu moyenera komanso kuchepetsa ndalama zamagetsi zomwe zimagwiritsidwa ntchito pa malo osungira deta. Malangizo a Kutentha a ASHRAE a Malo Osungira Data amathandiza makampaniwa kukhazikitsa njira yoti azitsatira ndikumvetsetsa bwino momwe zinthu zoziziritsira zamagetsi zimakhudzira zida zaukadaulo.

N’chifukwa chiyani ndikufunika kuyeza kutentha ndi chinyezi?

1.Kusunga kutentha ndi chinyezi m'malo osungira deta kungachepetse nthawi yopuma yosakonzekera yomwe imayamba chifukwa cha nyengo zachilengedwe ndipo kungapulumutse makampani madola masauzande ambiri kapena mamiliyoni ambiri chaka chilichonse. Pepala loyera la Green Grid lapitalo ("Mapu Ozizira Achilengedwe Osinthidwa a Airside: Impact of ASHRAE 2011 Allowable Ranges") likukambirana za mitundu yatsopano ya ASHRAE yomwe ikulangizidwa komanso yomwe ingaloledwe pokhudzana ndi kuzizira kwachilengedwe.

2.Chinyezi chonse mu data center sichiyenera kupitirira 0.006 g/kg kapena kupitirira 0.011 g/kg.

3.Kulamulira kutentha pa 20℃ ~ 24℃ ndiye chisankho chabwino kwambiri kuti makina azigwira ntchito bwino. Kuchuluka kwa kutentha kumeneku kumapereka chitetezo pakugwiritsa ntchito zida pamene makina oziziritsa mpweya kapena zida za HVAC zalephera, zomwe zimapangitsa kuti zikhale zosavuta kusunga chinyezi chokwanira. Kawirikawiri, sikoyenera kugwiritsa ntchito zida za IT m'malo osungira deta komwe kutentha kwa mlengalenga kumapitirira 30°C. Ndikoyenera kuti chinyezi cha mlengalenga chikhale pakati pa 45% ~ 55%.

Kuphatikiza apo, nthawi yeniyenichoyezera kutentha ndi chinyezimakina owunikira amafunika kuti athe kudziwitsa oyang'anira ntchito za malo osungira deta ndi kukonza za kusintha kosazolowereka kwa kutentha ndi chinyezi.

Kufunika kwa Kuwunika Kutentha kwa Kabati

"Malo ofunikira kwambiri" pankhani yofalitsa nkhani amatanthauza chochitika chofunikira, ndipo "malo ofunikira kwambiri" mkati mwa malo osungiramo zinthu zakale a data center amatanthauza chiopsezo chomwe chingachitike. Kuyang'anira kutentha pogwiritsa ntchito raki ndi kugwiritsa ntchitomasensa a kutenthamu ma racks a seva kuti muwasinthe pamanja kapena mwadongosolo kuti akhale ndi mulingo woyenera. Ngati mulibe njira yowunikira kutentha yochokera ku racks mu malo anu osungira deta, nazi zifukwa zingapo zoganizira izi.

1. Kutentha Kosakwanira Kungawononge Zida

Makina ndi ma seva a makompyuta adapangidwa kuti azigwira ntchito bwino pa kutentha kwina, osapitirira madigiri 24 Celsius. Nthawi yomweyo, ngati kutentha kozungulira chipangizocho sikuyendetsedwa bwino komanso kusamaliridwa bwino, chipangizocho chokha chidzatulutsa kutentha kwina ndipo chikhoza kudziwononga chokha. Kutentha kwambiri kumabweretsa chiopsezo cha kulephera kwa chipangizocho ndi kudziteteza, zomwe zingayambitsenso kuti chipangizocho chisagwire ntchito mosayembekezereka.

2. Mtengo wa Nthawi Yopuma Ndi Wokwera Mtengo

Kutentha kosalamulirika ndi chinthu chachiwiri chomwe chimayambitsa nthawi yosakonzekera yogwira ntchito ku malo osungira deta. Pakati pa 2010 ndi 2016 (nthawi ya zaka zisanu ndi chimodzi), ndalama zogwirira ntchito ku malo osungira deta zinakwera ndi 38 peresenti, ndipo izi zikuyembekezeka kupitirira kukwera m'zaka zikubwerazi. Ngati nthawi yogwira ntchito ndi pafupifupi mphindi 90, ndiye kuti mphindi iliyonse yogwira ntchito imawonjezera kwambiri ndalama, kuphatikizapo kuchuluka kwa antchito m'makampani a makasitomala a malo osungira deta. Mabizinesi ambiri masiku ano amayendetsa bizinesi yawo motsatira mtambo. Chimodzi mwa zifukwa zazikulu zomwe ndalama zogwirira ntchito ndi zokwera kwambiri ndikuti mabizinesi ambiri masiku ano amadalira ukadaulo wa mitambo. Mwachitsanzo, mphindi imodzi yogwira ntchito ku kampani yokhala ndi antchito 100 imayimira mphindi 100 yogwira ntchito. Kuphatikiza apo, chifukwa cha zotsatira zazikulu za mliri watsopano wa korona ndi kulumikizana kwa telefoni kukhala chizolowezi, nthawi yogwira ntchito ikhoza kukhala ndi zotsatira zazikulu pakupanga ndi ndalama.

3. Mpweya woziziritsa siwokwanira

Zachidziwikire, malo anu osungira deta ali ndi makina a HVAC, utsi wotentha, ndi zinthu zina zoziziritsira. Ngakhale makina oziziritsira mpweya awa omwe ali mkati mwa malo osungira deta amagwira ntchito kuti asunge kutentha koyenera, sangathe kuzindikira kapena kukonza mavuto a kutentha omwe amapezeka mkati mwa malo osungira ma seva. Pofika nthawi yomwe kutentha komwe kumatulutsidwa ndi zidazo kufika pamlingo wokwanira kusintha kutentha konse, kungakhale kuchedwa kwambiri.

Popeza kutentha kumasiyana malinga ndi chikombole cha chipangizo chilichonse mkati mwa malo amodzi a data, kuyang'anira kutentha kwa chipangizocho ndi njira yabwino kwambiri yopewera kuwonongeka kwa zipangizo za IT. Kugwirizana bwino kwa ma PDU anzeru ndimasensa a kutentha ndi chinyezimkati mwa ma racks kudzabweretsa phindu losalekeza pakupezeka kwakukulu kwa zomangamanga za malo osungira deta.
