Chabwino, kapena lipirani kuwirikiza kawiri pa taxi monga mwanthawi zonse. M'mawa, werengerani nthawi mosamala kuti mlathowo ukangotsekedwa, mumapita ku siteshoni ngati mongoose wothamanga. Sitikuwona kuti kusankha "kugona kwinakwake pakati, pafupi ndi siteshoni" ngati yovulaza.
..."Peregrine Falcon", kuchoka pa 5:30, idapangidwa ndi anthu omwe amadana ndi akadzidzi. Ayi, ndithudi, ndibwino kwambiri kukhala ku Moscow 270 koloko m'mawa, ndipo St. madigiri ku lark yemwe adapanga sitima yam'mawa uno.
"Malo onse abwino a data ndi ofanana," ndinaganiza nditazindikira kuti anyamata ochokera ku DataLine adatiitana kuti tidzacheze.
Pamene zikuwonekera, malo aliwonse a deta ndi abwino (kapena oipa) pang'ono mwa njira yake, makamaka mukagunda nthawi yayikulu, sonkhanitsani ma rakes onse m'deralo ndikuphunzirani maphunziro anu (ndipo, pang'ono, anthu ena). ) chokumana nacho cholemera. Chifukwa chake ife (opangidwa ndi ma linkmeup asanu otsogola ndi abwenzi awo ndi omvera) adaganiza zoyang'ana momwe malo opangira data a OST ndi NORD alili abwino (kapena ayi).
Titakwanitsa kuchita ntchito yaying'ono pamsewu (pakhoza kukhala zotsatsa za oyendetsa mafoni apa, koma ayi - kufalitsa kunali koyipa), tidatsitsa pa siteshoni ya Leningradsky. Chabwino, osati pansi pa Gazmanov.
Tinayamba ulendo wathu wopita kumalo osungiramo data "laimu" ndi OST - "yemweyo" yomwe "inawotcha" osati kale kwambiri. Chifukwa chiyani m'mawu - pambuyo pake. Pakali pano, timaima, kusuta, ndi kuyembekezera amene achedwa. Kujambula zithunzi za ofesi ya RT yoyandikana nayo. Pali nkhani zambiri zoseketsa za m'derali - kuyambira kuyika phula mwatsopano ndi penti zotchinga pamaso pa olemekezeka, kuchotsera m'malesitilanti oyandikana nawo omwe adaperekedwa kwa okhala ku Dataline chifukwa cha kufanana kwa mabaji awo.

Zithunzi zikuwonetsa malo a data a NORD
Ulendo umayambira kuofesi. Kuphatikiza pa zolembedwa pamakoma ndi mtundu woyera ndi laimu wodziwika mu Runet yonse, palinso mitundu yonse ya zinthu zoseketsa. Izi ndi zotsalira zomwe zatsala kuchokera ku zisudzo zamakampani (mungayerekeze wotsogolera zaukadaulo wa network ya data center akusewera sewero? Ndipo timamudziwa payekha).
Ndipo ndi zoona
Zithunzi zochokera ku zisudzo
Deta ya data (kapena m'malo, malo anayi a deta) ali mu nyumba zovuta za mafakitale zomwe zinamangidwa m'zaka za zana lapitalo (ndiye chomera cha Citroen, ndi nthawi ya Soviet mbewu ya Gidroprivod), kotero kumbali imodzi pali zovuta. kuyang'ana kwa mafakitale, zitsulo zazitsulo, malo okwera pamwamba ndi zinthu zakale zamafakitale kuchokera ku nthawi zosiyanasiyana zomwe zimapezekabe pa ntchito zosiyanasiyana. Kumbali inayi, madera a hermetic a data center ayenera kukhala ogwirizana ndi zomwe zilipo kale, ndipo kusagwirizana ndi zenizeni kuyenera kupangidwa nthawi ndi nthawi. Komabe, sindinganene kuti kusagwirizana uku kunakhudza khalidweli - koma anyamatawo ayenera kuti anagwira ntchito mwakhama popanga. Komanso, malinga ndi mphekesera, Metro-2 imadutsa kwinakwake pafupi, koma izi sizotsimikizika.
Kuphatikiza pa zisudzo, palinso nyumba yosungiramo zinthu zakale. Ziwonetsero, mwachibadwa - zofukulidwa zakale
Mawu ochepa za . Inde, nyumbayo (kapena kani, denga) inali yoyaka moto. Magawo akunja a machitidwe ozizira ndi mapaipi ozizira adawonongeka. Penapake mawaya anapsa ndipo ma air conditioners anatsala opanda magetsi. Mapaipi a Freon anaphulika penapake. Koma, ngakhale izi, madera hermetic kupirira matani madzi anathiridwa pa iwo, ndi zida anapulumuka. Anabwezeretsanso pansi pa ulamuliro wa "likulu" loyimiridwa ndi oyang'anira akuluakulu a dziko lonse lapansi - adatulutsa mapaipi onse amkuwa ku Moscow ndi madera ozungulira (iwo adawabweretsa usiku mu BMW X5) ndi onse opanda nzeru. okhazikitsa.

Tikuyenda m'makonde, tikuwona chiwonetsero chogwira ndi chinthu chofanana kwambiri ndi chithunzi cha zipinda za turbine za data center. Ili ndiye gulu loyimira. Pali zambiri m'makonde, ndipo amalola mainjiniya omwe ali pamalowo kuti apeze mwachangu, mwachitsanzo, chowongolera mpweya chofunikira, ndikungonena momwe zilili.
Kuyang'anira kumamangidwa pa Nagios (tsopano pali magulu angapo odziyimira pawokha) ndipo imakhudza malo onse a data (onse OST ndi NORD). Kuphatikiza apo, pali mapulogalamu a Android ndi iOS (makasitomala ndi antchito), komanso tsamba lawebusayiti mwachindunji patsamba.
Pachiwonetsero ndikuwona PUE yapamwamba kwambiri - sichivomerezedwa kulikonse ku Russia, komabe 1.90 ndipamwamba kwambiri. Yankho la izi ndi zachuma - mu 2012-2013, ma racks m'malo osungiramo data anali kugulitsa ngati makeke otentha, kotero panalibe nthawi yokhudzika ndi mphamvu. Timayika zomwe zili pamsika, chitani mwamsanga ndipo osasamala za PUE yanu konse, chifukwa chiyani? Ngakhale pamapangidwe, 80-90% ya ma racks amagulidwa, koma malamulo a Russian Federation sakufuna kudziwa chilichonse chokhudza mphamvu zamagetsi. Ngakhale komiti ina ku Amsterdam ingakhutitsidwe ndi ziwerengero zoterezi.
Palibe munthu. Bizinesi basi.

Timayima pa Meet-Me-Room, komwe ogwira ntchito amakhala. Mu MMR (pali awiriawiri atatu mu OST, malinga ndi kuchuluka kwa zolowetsa zazikulu za kuwala, zogwira ntchito ndi zopanda pake) zolumikizira kuchokera ku holo zonse za data zimaphatikizidwa. Mu nsapato zamtundu uliwonse ndizotopetsa komanso zowoneka bwino. Koma komwe kamera imagwira ntchito, mumakumbukira zaka zabwino kwambiri ndi zojambula kuchokera ku BM18: Zakudyazi zopangidwa ndi mawaya ndi zida zosiyanasiyana (DLink, Extreme, Juniper, Mikrotik ... ndi zina zotero mpaka ASR9k). Pali oposa makumi asanu ogwira ntchito pano, kotero chirichonse chiri chokongola. Kuchokera ku MMR, optics ndi mkuwa zimagawidwa kuzipinda zamakina. Njira zosachepera ziwiri zamtundu uliwonse (zosiyanasiyana ndizotheka), kotero simuyenera kuda nkhawa ndi kudalirika kwa kulumikizanako. MMR imatchedwa "Elbe", yomwe ndi yochenjera kwambiri.

Kupeza kwina ndi IBM P-series, yomwe siinayambe yatsegulidwa, ndipo yakhala ikuyimirira mu imodzi mwa makonde kwa zaka zingapo. Makina (pamodzi ndi laibulale ya tepi ndi makina osungira) adalamulidwa ndi mmodzi wa makasitomala, koma "sanali othandiza," kotero adaperekedwa ku data center. Icho chakhala chikuyima kuyambira pamenepo.
Ndikwabwino kukhala anyamata olemera ndikupatsa mphatso zotere, sichoncho? (Kapena mwina sanapereke ngati mphatso, koma anaiwala. Kapena anataya pa makadi. Koma izo zakhalapo kwa nthawi yaitali)
Mnyamata wokongola uyu wayima ku NORD-4
Timapita ku malo opangira mphamvu - atatu (kapena anayi) ma jenereta a dizilo pa malo aliwonse a deta (ndiroleni ndikukumbutseni, pali anayi mwa iwo mu OST). Dizilo injini kufika mphamvu zonse 30-40 masekondi ndipo umabala 1900 kVA. N+1 redundancy, kulunzanitsa, ndi zina. Nthawi yayitali kwambiri pa injini za dizilo mu OST ndi maola 12. mu NORD - masiku 2.5 (pambuyo pake, malo osungirako matani 85 si ndalama zambiri).
Zachidziwikire, pali mapangano ndi makampani osiyanasiyana amafuta operekera mafuta. Kusintha kwa dizilo kumachitika nthawi zonse, kotero kuti mafuta onse amapangidwa ndi mapangano amatsimikiziridwa. Mwa njira, malinga ndi ogwira nawo ntchito, ku NORD, poyesa seti ya jenereta ya dizilo, yomwe nthawi zambiri imatenga nthawi yopitilira ola limodzi, pamalo pomwe mpweya wotentha wochokera ku injini za dizilo umatuluka, ngakhale m'nyengo yozizira udzu umatha kutembenukira wobiriwira.
Titadya pang'ono pa malo ogulitsira khofi omwe timawadziwa, timapita kumalo a NORD. Izi sizilinso malo amodzi a deta, koma nyumba zinayi zodziimira pagawo lomwelo. Iliyonse ili ndi zolowetsa zake zamagetsi, ma injini ake a dizilo ndi kuziziritsa kwake. NORD-1 ndi NORD-2 adawunikidwa ndi Uptime Institute M&O. Zaposachedwa (ndi malo abwino kwambiri a DataLine) ndi NORD-4, kotero ndi kumene tikupita.
Ngakhale kuti malo osungiramo data akuwoneka ngati ochuluka ku Moscow, akusowabe. Ayi, ndithudi, rack imodzi kapena ziwiri zidzatumizidwa kwa inu popanda vuto lililonse. Iwo akukupatsani inu makumi awiri. Zambiri ndi funso (ndipo DataLine ili ndi makasitomala opitilira m'modzi kapena awiri omwe ali ndi zosowa zotere). Makamaka, mu NORD-4 pali malo (pakadali pano), chifukwa kasitomala wamkulu wasamukira kumalo ake omwe adamangidwa kumene, koma m'malo ena izi sizingakhale zabwino. Komabe, mapangidwe a NORD-5 tsopano ali pachimake, omwe adalonjezedwa kuti adzakhazikitsidwa koyambirira kwa 2020.
Koma tiyeni tibwerere ku ulendo wathu. Popeza kuti tinali kuyenda pa galimoto, anatilowetsa pachipata, kumene onyamula mfuti anatilondolera, kuyangβana nambala ya galimoto yathu ndi mafomu ofunsira, ndipo anapempha okwera onse kutuluka kuti akatenge ziphaso (ndithudi ndi mapasipoti awo). Chifukwa B ndi chitetezo.
NORD-4 ndiye kunyada kwa kampaniyo ndikuphatikiza zaka zambiri zazaka zambiri pantchito yomanga ndikugwiritsa ntchito malo opangira ma data, ili ndi ziphaso za Uptime Institute Tier III zamapulojekiti opanga ndi Malo (ie adamanga data center), komanso Operational Sustainability - anyamatawo adayandikira nkhaniyi mosamala momwe angathere.

Pakhomo la data center, sitolo ya khofi yomwe timadziwa kale ikuyembekezera (chabwino, bwanji?). Timapita ku malo oyang'anira. Tsopano pali zazikulu ziwiri - mu OST ndi NORD-4 (NORD-1,2,3 ilinso ndi masinthidwe awoawo). Kuchokera pakati pa aliyense mutha kuyang'ana masamba onsewa, kotero ngakhale apa redundancy n+1 imatsimikizika. Pakhoma la kanema pali ma dashboards omwe amadziwika kale mumtundu wobiriwira wobiriwira (pali, ndithudi, magawo ambiri kuposa momwe amawonetsera). Timalumikizana pang'ono za kuwunika - palibe Prometheus ndi Grafan wapamwamba, Nagios yekha, mawonekedwe olimba komanso opangidwa kunyumba. Pazaka khumi (komabe, zochulukirapo) zogwiritsidwa ntchito, macheke ambiri ndi zolemba zalembedwa kale, kotero kusinthira ku chinthu china kumawoneka ngati njuga. Pafupifupi kamodzi pamwezi kumawoneka kampani ina yomwe imadzipereka kuthetsa mavuto onse "mwachangu komanso mopanda ululu," koma mwanjira ina sizikuyenda. Khoma la kanema, mwa njira, limagwiranso ntchito pa njira yokhayokha, yomwe idakhala yotsika mtengo kangapo kuposa ma analogue amalonda.
Malo oyang'anira malo
Pamene mwakhala mukupanga, kumanga ndi kugwiritsa ntchito malo opangira deta kwa zaka zambiri, simukuwopanso kuchita chinachake nokha kusiyana ndi kugula chinachake chokonzekera. DataLine, mwachitsanzo, sazengereza kunena kuti, chifukwa cha kukula, adapondapo zolakwika zambiri, ndipo malo atsopano a deta ndi zotsatira za zolakwika zovuta ndi zochitika zomwe zakhala zikuchitika kwa zaka zoposa khumi. . Zoonadi, malo aliwonse atsopano a deta ali ndi chidziwitso chake, ndipo pamene mukuyenda mozungulira NORD, nthawi ndi nthawi mumadzipeza nokha kuganiza kuti anthu adangozichita ndikuzichita bwino. Osati chifukwa chodziwonetsera, osati chifukwa cha mavoti ndi ziphaso - ndondomeko yaumisiri wamba, pamene nthawi zonse mumakula pamwamba panu ndikukhala bwino komanso bwino. Woyang'anira wakunja anganene kuti izi ndizotopetsa komanso zosasamala, koma kasitomala, m'malo mwake, amakhalabe okhazikika ndi ndalama zake. Ndipo kuti muchite bwino, sikofunikira konse kugula machitidwe aumisiri kapena mapulogalamu ambiri, ndalama zambiri (ngakhale nthawi zina simungathe kuchita popanda izo). Zochitika, chidziwitso ndi luso laumisiri nthawi zambiri zimasankha.
Mwachitsanzo, nyumba ya NORD-4 ili ndi 3,5 pansi. Zoyamba zitatu ndizodzaza, zokhala ndi denga la mamita 4.5, kumene zipinda za turbine zili. Ndipo yomaliza ndi yaukadaulo, kutalika kwa mita 1.8 yokha, ndipo idaperekedwa ku makina ozizirira okha. Popeza pansi ndi luso, zofunikira zake ndizochepa kwambiri, zomwe zinapangitsa kuti polojekitiyi ikhale yosavuta ndikusunga ndalama.

Max ali ndi luso lapadera la kung fu kuti asatenthedwe pazithunzi
Timamaliza ulendowu padenga - kuchokera pano tili ndi malingaliro abwino kwambiri a pafupi ndi malo opangira magetsi otentha ndi malo okhalamo, komanso nyumba zina za NORD. Awiri a iwo ndi atatu. Pazifukwa izi, ogwira nawo ntchito adaseka kuti "DataLine ndi ma moons, pazifukwa zina akumanga malo opangira ma data atatu" kuti akhazikitse ma racks a triangular ndi ma seva a triangular kumeneko. Koma palibe - adamanga ndipo akugwira ntchito bwino, ndipo panthawi imodzimodziyo akugwiritsa ntchito gawo lomwe lilipo (lomwe ku Moscow, ziyenera kunenedwa, si zaulere). Chinanso chodabwitsa (kwa ine) ndikuti ambiri mwamakasitomala azamalonda akufuna kukhala ku Moscow. Malo omwe ali pamtunda wa makilomita theka la kilomita limodzi ndi Minsk Highway (ngakhale pali zofunikira zonse ndi mauthenga) salinso chidwi ndi aliyense. Choncho, aliyense amangokhalira kukangana popanda mphira.

Ndi ichi ulendo wathu wotsatira wafika kumapeto.
Pambuyo pake panali kukambirana kwinanso kwautali komanso kopindulitsa pa mapulani ophatikizana ndi ma podcasts amtsogolo (ndikukhulupirira kuti sitiyenera kudikirira nthawi yayitali), choncho khalani tcheru, padzakhala zinthu zosangalatsa kwambiri posachedwa.
Chabwino, ngati mukufuna kuwona chilichonse ndi maso anu, DataLine ikukuitanani paulendo. Mfulu kwathunthu, koma mwa kusankhidwa. Iwo omwe amatcha mawu oti "linkmeup" apeza zowonjezera mu karma.
