Masiku oyambirira a chilimwe ndi abwino kwa ulendo wa maphunziro ku St.
Tidzayendera Miran, linxdatacenter, RETN ndi Metrotek.

5 am, Moskovsky station, KFC, Moika embankment, Plate, njiwa zochokera padenga, St. Isaac's, Field of Mars, Yandex drive Capture, ndipo apa ndi - Miran.

Miran

Labu yathu ndi Eva, seva yowulutsa, Mikrotik Routeros yodziwika bwino, yolumikizira kulumikizana ndi kupezeka kwa IPv6, ndipo tsopano kuchititsa ma podcast akhala ku Mirana kwa zaka zingapo tsopano.

Pakhomo la Miran tinalandilidwa koyamba ndi fakitale yochititsa chidwi ya dizilo.

Ma Diesel Generator Sets ambiri ali pamawilo pazifukwa ziwiri:

• Kusuntha - pali ma module angapo a Mirana pamtunda wa mita mazana angapo. Ali ndi ma jenereta awo - koma simudziwa - muyenera kuwagudubuza.
• Kusuntha - safunikira kulembetsedwa ngati malo opangira magetsi osasunthika ndipo, motero, palibe zolemba zamapangidwe zomwe zimafunikira.

DGU Mirana m'nyengo yozizira ndi chilimwe imayamba mumasekondi pang'ono. Panthawiyi, malo onse a data amayendetsedwa ndi mabatire.

Onse chitsulo HP mu kaimidwe Miran ndi ulendo anakhala zotheka chifukwa Fedor Rusakov.

Ulendo wonsewo unachitika mumkhalidwe wabwino wapakhomo. Khofi ndi ma cookies, kukambirana za telecoms, za chiyambi cha kampaniyo, za kutumiza ma seva mazana awiri a vkshechka kuchokera ku Moscow kupita ku St. Petersburg pansi pa mdima. Tinayenda momasuka kudutsa nyumba ziwiri za data center. Onsewa ndi matembenuzidwe a BrownField kuchokera kumafakitale. Mu woyamba, mwini wa Miran, kumene tinayambira ndi kumene pansi yachiwiri ife recharged pambuyo maola anayi kuyenda kuzungulira St. Kwenikweni kunalibe kusanja kwachiwiri - kunali zipata zazikulu zopita uku ndi uku. Chilichonse chinang'ambika, chipinda chachiwiri chinamangidwa, kuziziritsa mwachangu, magetsi osagwiritsidwa ntchito, makina ozimitsa moto wa gasi.

Njira yotentha yotentha, yochokera komwe mpweya umaperekedwa ku zoziziritsa mpweya komanso pansi pa malo okwera munjira yozizirira yotsekedwa.

Zingwe zamagetsi zimabisikanso pansi pa nthaka yokwezeka.

Miran sanabadwe ngati nsanja ya kasitomala m'modzi, koma adapanga mwadongosolo zomwe amapeza pamsika pomwe pakufunika.

Panthawi ina panali banki yaikulu pano ndi alonda onse ofunikira otetezera ndi machitidwe olowera, koma yachoka kale.

Kufuna kunapitilira kukula, Miran nayenso, nyumba yachiwiri idawonekera - yobwereka kale - komanso BrownField - mamita mazana awiri kuchokera koyamba. Msewuwu umadutsa mpanda wa Bolshaya Nevka kudutsa nyumba ya Nobel.

Nyumba yatsopanoyi imamangidwa pa mfundo ya modular yomwe imatha kunyamula gawo lonselo pakagwa mavuto ndi eni nyumba. Mabokosi awiri oyambirira adagulidwa kuchokera kwa wopanga, wachitatu anali atasonkhanitsidwa kale poganizira zolakwika zakale.

Zomangamanga modular zidakhala ndi zovuta - ndizopapatiza - khonde lotentha ndi 60 cm - anthu awiri sangathe kupatukana. Ndipo chofunika kwambiri, mtengo wosuntha, monga momwe zinakhalira pa kuwerengera koyamba, ukufanana ndi kumanga watsopano.

Koma amawoneka atsopano komanso apamwamba kunja ndi mkati.

NOC ya anyamata pa Orthodox Linux, Debian wokhazikika.

Kampaniyo, mwa njira, idatenga dzina lake kuchokera ku board ya Meridian Integrated Recorded Announcement (MIRAN) mu switch yafoni ya Meridian. Ndipo zitatha izi, malo opangira data adatchedwa choncho.

Anaganiza zomanga malo osungiramo data m'chaka chovuta cha 2008.

Kuyambira pamenepo, anyamata akhala akupereka dedik ndi belu. Zida za opareta zimayikidwa muzipinda zapadera.

Ndipo izi zimayika zoletsa zina ndi mawonekedwe pa ntchitoyi. Mwachitsanzo, ma racks ali ndi zida zosiyanasiyana, zonse zokhudzana ndi makina komanso maukonde. Ku Miran, sindinawone Arista ndi Mellanox. Zida zonse zimakhala ndi zofunikira zosiyana pa kutentha kwa khonde lozizira, choncho ziyenera kusungidwa pamtunda wotsika kwambiri - pafupifupi 20 ° C, ndiye kuti, palibe chifukwa cholankhula za PUE yochepa - Miran ali nayo 1,5.
Chinthu chinanso ndi maukwati a njoka m'malo oimilira. Mukangolola anzanu akunja kulowa mchipindamo ndi maulalo awo, lembani "kukongola kwatha." Palibe amene ali ndi zosiyana.

Tsoka ilo, kubweretsa njira zopanda pake pano kungakhale kowononga.

Zithunzi zaposachedwa.

Kenako gulitsani kuchokera patebulo lathu kupita lanu ndi lanu mpaka lathu. Khamu lonselo linakwera m’mataxi ndi kumalumikizidwe.

kutuloji

Awa ndi anyamata okhwima, omwe chiphaso chawo chaching'ono chimati "Nkhani Zachitetezo." Ichi chidzakhala chochititsa chidwi cha ulendo wonsewo.

Pambuyo pa Miran ya gingerbread ku linxdatacenter, mukumvetsetsa kuti DC yapamwamba yafika. Patsiku lawo lopuma, anthu 4 adasonkhana, kunena zoona, osati pakati pa mzindawo kuti aziuza anthu ena asanu omwe sangakhale makasitomala awo :)

Maria Svistunova anakumana nafe n’kupita nafe patebulo lalikulu lochitira zokambirana. Kukambitsirana kwachabechabe pa khofi waku Guatemala ndipo timapita.

Maulendo akutsatiridwa pano. Maxim ndi Oleg amadziwa zinthu zawo: amazinena ngati akudziwa: momveka bwino komanso mwachidwi. Pamene kuli kofunikira, amagogomezera, ndipo ngati kuli kofunika, amalambalala. Kuseketsa kulinso mwadongosolo, kotero kuti maola opitilira awiri adawuluka mosadziwikiratu.

Kunyada kwa data center ndi 100% uptime kuyambira pomwe idakhazikitsidwa mu 2011.

Chidaliro ndichokwera kwambiri kotero kuti palibe ngakhale malo pa bolodi la magawo khumi.

Linx ndi chitsanzo cha DC mu mtundu wa GreenField. Nyumbayi idamangidwa mwapadera kuti ikhale ndi DC. Choncho, kutalika kwa denga, mphamvu ya pansi, zopangira magetsi, redundancy, SCS - zinaphatikizidwa mu polojekitiyi ndikuganiziridwa pa ntchito yomanga.

Chifukwa chake, mwachisawawa, pansi pakhoza kupirira 800 kg, koma kulemera kumatha kuonjezedwa pambuyo powonjezera kulimbitsa. Amati ma rack a Oracle okwera mtengo a Falcon9 amafunikira chithandizo chapadera.

DC palokha imayendetsedwa ndi kuyika kwa gasi-piston, ndipo magetsi amzindawu ndi malo osungira. Malingana ndi Maxim, ichi chinali chisankho cholondola kwambiri, chifukwa pa nthawi yakuda yakuda ya St.

Jenereta wa dizilo pano salinso kalavani yamawilo, koma chipinda chosasunthika chokhala ndi machumuni okwera pamwamba pa malo.

Nthawi yoyambira siyiposa mphindi ziwiri, ndipo malo onse a data amatha kugwira ntchito pa mabatire pafupifupi ola limodzi. Ma injini a dizilo amatha kugwira ntchito kwa masiku atatu popanda kuwonjezera mafuta.

Pali dongosolo ndi kulingalira mu chirichonse pano.

Izi ndi, mwachitsanzo, Klyuchintsa, kumene makasitomala a data center amatha kutenga makiyi a rack zawo pogwiritsa ntchito zala zawo.

Ndipo ichi ndi chipinda chomwe makasitomala amatha kugwira ntchito iliyonse yaumisiri yomwe angafune, yomwe chida chokhazikika chimapachikidwa pakhoma.

Awa ndi mashelufu kale ogwiritsidwa ntchito kwanuko ndi chilichonse chofunikira pantchito yatsiku ndi tsiku:

Nthawi zonse imakhala yolipitsidwa ndipo ili yokonzeka kupita.

Chipewa cha baseball cha hiphopper yemwe akufuna kukhala pachithunzi pamwambapa chidasunga mutu wa anthu opitilira m'modzi. Ndizovuta ngati chisoti chachilengedwe - chinthu chabwino kuchita ndikukwera pansi pamtunda wa mita imodzi ndi theka, pomwe, ayi, ayi, chitsulo china chakuthwa chikutuluka.

Kwenikweni ogwira ntchito:

Chipangizo chodabwitsa ichi ndi choyezera kuthamanga kosiyana.

Zapangidwa kuti zithetse vuto losavuta - kusunga kusiyana kwapakati pakati pa korido ndi chipinda cha makina. Mwachitsanzo, kuti ikhale yokwera pang'ono mkati ndipo chitseko chikatsegulidwa, fumbi siliwulukira mkati, koma limawulukira kutali ndi chitseko.

Njira yozimitsira moto ndi gasi - pakagwa vuto, mpweyawo umatulutsa mpweya ndikusiya kuyaka.

Anyamata okhawo okhwima komanso ozama kwambiri omwe ali ndi zifukwa za paranoia kukula kwa Ararati amaima pamalumikizidwe.

Grilles ndi njira yosiyana yolowera ku data center ndi chiyambi chabe.

Pamene anthu awiri abwera kudzathetsa vuto kapena kupanga maulumikizidwe atsopano - wina ali ndi kiyi yakuthupi, wina ndi wamagetsi - izi zimakhala zosangalatsa kwambiri. Ndipo pamene wowerengera wowoneka bwino afika kuchokera kwa kasitomala, amatsikira pansi pa nthaka yokwezeka, amachotsa mapepala awiri a mipiringidzo ndikunena kuti mutu wa mwana udzakwanira pano, mumamvetsetsa kuti munthuyo wawona zinthu zosangalatsa pamoyo wake.

Panali zochitika zoseketsa pamene, popanga khola, amaganizira zonse zomwe zingatheke, machitidwe onse otetezera, miyeso yonse yomwe imakulolani kuti mulowetse choyikapo ndikuyika zida mmenemo, koma mwanjira ina iwo sanaganizire za kukula kwake. mainjiniya omwe angagwire nawo ntchito. Koma sagwirizana pakati pa khola ndi choyimilira mwina kutsogolo kapena mbiri.

Ndikadakhala FSB, ndikadayika zida zanga mu linx :)

Pambuyo pa ulendowu, tinakhala kwa nthawi yaitali, tikumacheza pa pizza.
Kuchokera kudera lachitetezo ndi dongosolo lino tinasamukira ku RETN.

Zotsatira RETN

Anyamatawa takhala tikuwadziwa kuyambira kalekale. Choncho, n’zosadabwitsa kuti pomalizira pake tinasonkhana padenga la nyumba yawo kukawotcha nyama ndi kukamba nkhani.

Ifenso tinapitako kwa iwo kale, ngakhale ine sindikuganiza kuti ife tinakuuzani inu za izo. Chaka chatha, mapulani olanda madenga a St. Petersburg analephera chifukwa cha Fifa.

RETN ndiyomwe imagwiritsa ntchito msana waukulu kwambiri wokhala ndi ulusi padziko lonse lapansi. Ukonde wawo udzakhala nsanje ya kangaude aliyense.

Ndipo DC pa Obvodny ndi ntchito yapanyumba ya moyo yomwe yapeza malo ake pamsika womwe ukukula. Apa ndipamene omwe amafunikira kulumikizana mwamphamvu ndi dziko lapansi komanso mwayi wolumikizana ndi othandizira ena am'deralo amabwera.

Mwachitsanzo, RETN ili ndi CDN ya Netflix.

Ndinadabwa kumva kuti mfundo zawo zonse zinasaina pamanja ndi mawu.
Ndipo mabokosi atchuthiwa akuphwanyidwa m'mizinda yosiyana pa ma POP a RETN (ndipo, mwachiwonekere, osati izo zokha), kukupatsirani "Black Mirror" ndi "Peaky Blinders" kwa inu mwamsanga momwe mungathere.

Palinso CDN ya Google ndi gulu la ogwira ntchito, am'deralo ndi aboma.

RETN ili ndi ma jenereta a dizilo ang'onoang'ono awiri (poyerekeza ndi a Miranov) ndi galimoto yokhala ndi zitini zopitira kumalo opangira mafuta pafupi ndi nyumbayo. Zikumveka ngati bizinesi yabanja.

Chabwino, zokambirana zamadzulo padenga zidatifikitsa poti RETN ingatipatse bokosi la malo osungiramo ma podcasts ndi zithunzi.
Anyamata a padziko lapansi, malo apamwamba kwambiri a data, maukonde omwe amadabwitsa ndi kukula kwake.

Kwa ena, tsikuli linatha ndi mpikisano wa duke nukem, kwa ena ndi tulo tomwe tikuyembekezera kwa nthawi yayitali mu hotelo.

Tsiku lotsatira tinalibe mapulani ambiri: Metrotek ndi podcast live - kulumikizana ndi IRL.

Metrotek

Mwezi wapitawo tinayendera podcast ya telecom anabwera Misha Sokolov ndi Denis Gabidullin ochokera ku STC Metrotek slash Plumspace, ndipo tinakambirana kuti Smart SFP ndi chiyani. Ndipo tsopano tinali okhoza kuwagwira amoyo.

Denis, amene anachezera ofesi ya St. Petersburg ya Metrotek (yomwe, mwa njira, sinasinthe chiyambire ulendo wathu womaliza kwa iwo), anaperekadi chitsanzo chimodzi kuchokera pakhomo pomwe.
Poyamba ndidadabwa momwe zidapangidwira mwankhanza - ngati kuti zidapangidwa kuchokera ku wrench ya 32mm yokhala ndi jigsaw ndi fayilo.

Zinapezeka kuti thupi la prototype linali 3D losindikizidwa kuchokera ku ufa wachitsulo, monga momwe tingawonere pamtunda wovuta. Ena - omwe ali okonzekera mndandanda - ali mu dongosolo langwiro.

Koma nthawi zambiri, mukamawayang'ana, mumadabwa ndi momwe adakwanitsa kubisala ubongo wambiri pamtundu wamba.

Ndikukulangizani kuti mumvetsere podcast yokhudza Rosa, Tozu ndi mlongo wawo Boza. Zinakhala zosangalatsa kukoma kwanga.

Mapangidwe a ofesi ndi wamba momwe angathere. Maofesi ang'onoang'ono amakona anayi, omwe adatambasulidwa pawindo, ndi mdima wandiweyani, womwe unali wopondereza. Koma mlengalenga, ngakhale tsiku lopuma, linali lofanana ndi ntchito.

Mapangidwewo sanasinthe m'zaka ziwiri. Ndinakondwera ndi zikwangwani ndi matabwa.

Tinadutsa m'zipinda zingapo: R & D, akatswiri opanga makina, akatswiri a FPGA, omwe ali m'manja mwathu mitundu yosiyanasiyana ya SFP, olemba mapulogalamu, adawona chitsanzo choyamba chomwe Smart adachotsedwa ku SFP pawaya - chimodzi mwa zoyesera zoyamba - m'malo mwake, a. Umboni wa Concept kuti umagwira ntchito konse .

Iwo amati makasitomala ena amaona kuti n’koyenera kukhala ndi mchira woterowo utatuluka muchitsulo.
Cholinga choyambirira kwambiri zaka ziwiri zapitazo chinali kusonkhanitsa SFP yowoneka bwino yomwe ingatumize chizindikiro.

Kenaka adasonkhanitsa padera gawo la Smart ndi SFP ya munthu wina (pa chingwe) kuti atsimikizire kuti adatha kusonkhanitsa tchipisi.

Metrotek yachita ntchito yabwino. Tangoganizani kuti m'zaka za 2 adasonkhanitsa gawo logwira ntchito bwino lomwe limatha kuyika, telemetry, seva yanthawi yeniyeni, ndi chosinthira mawonekedwe.

Ndipo nthawi yomweyo, sinthani ku ungwiro (ngakhale izi zikuyenera kuyesedwa ndi nthawi) ntchito yoyambira yotumizira ma siginecha. Sipayenera kukhala kuchepetsedwa, pasakhale ngakhale madontho osowa chifukwa cha vuto la SFP. Ndipo sayenera kutentha, ngakhale ali ndi paketi ya ASICs, FPGAs ndi CPUs mkati.
Bravo!

Computing System:

• CPU: NXP i.MX6 ARM mpaka 900 MHz
• FPGA: Lattice ECP5 mpaka 85K LUTs
• RAM: DDR3 mpaka 1 GB

Denis adanenanso kuti kampaniyo imachita ndikulimbikitsa kusinthana kwa chidziwitso ndi chidziwitso. Ndiyeno ndinaganiza: “Kodi zingathekedi? 0_o." - Inde, nthawi zambiri anthu amabwera kwa iwo omwe, kumalo awo oyambirira a ntchito, amadya timadziti tawo, osalankhulana, adagwira ntchito ziwiri ndi zitatu ndipo nthawi zambiri amapewa kuyesa kulankhulana.

Ndiyeno ndinakumbukira kuti, kawirikawiri, osati zaka ziwiri zapitazo ndinagwira ntchito ku kampani yapadziko lonse, yoletsedwa kwambiri, kumene misonkhano inali yoletsedwa ndipo kusinthanitsa chidziwitso kunalibe ngati kalasi. Ndipo ndinali m’modzi wa alaliki amisonkhano yosinthana mlungu ndi mlungu yomwe inkawoneka ngati ikupulumutsa mainjiniya osungulumwa m’madera akutali.

Kawirikawiri, Metrotek nthawi zonse imapanga maphunziro amkati ndi maphunziro, chifukwa chake ndi abwino.

Ndiyeno tinatengedwera ku malo ochitirako makhazikitsidwe odabwitsa. Ngakhale ndimawachezera kangati, zikuoneka kuti chisangalalo changa chaubwana sichizilala.

Metrotek ili ndi zida zosindikizira pama board ozungulira muofesi momwemo.

Cholembera chogwiritsira ntchito ma pellets a solder, chosindikizira cha zigawo za SMD (sindingathe kuzitcha china chilichonse), chitofu chaching'ono chophikira matabwa ozungulira ndi malo ogwirira ntchito pafupi kuti akhazikitse pamanja.

Ndinadabwa kuona kuti tinthu tating'onoting'ono tokhala ndi miyendo yambirimbiri timagulitsiranso pamanja. Denis akunena kuti anyamata awo amagulitsa zigawo zing'onozing'ono ndi zolondola modabwitsa komanso mofulumira, ndipo nthawi zina palibe chifukwa choyendetsa makina a shaitan - munthu adzachita mofulumira.

Tinatcha mzere wopanga Metrotek Eltex-Verilight pakati pathu, chifukwa cha ulendo waposachedwa kwa iwo.

Kuphatikiza apo, ofesiyi ili ndi chosindikizira cha 3D ndi makina opangira mphero pazosowa zamkati, zomwe, komabe, zidagwiritsidwa ntchito kale kulemba mendulo zachaka chatha. Chaos Construction.

Kuchokera kumeneko tidapita ku Krang Pizza, zodabwitsa mumalingaliro ake, pomwe gulu lonse la linkmeup linameza burger ya pizza yomwe inali yosinthika mu kukula ndi tanthauzo ndikusamukira ku ofesi ya IQ, komwe tidalemba gawo loyamba. kulumikizana ndi IRL.

Tsiku lotsatira, tidayang'ananso Laser Center pansonga yochokera ku Mammoth, komwe tidakumana ndi chisangalalo chaukadaulo komanso kutupa pang'ono kwa umbombo, koma iyi ikhala nkhani yosiyana.

Pomaliza, ndikufuna kunena kuti maulendo onse ndi misonkhano inakhala yosiyana kwambiri, ponse pakuchita komanso kuyang'ana.

Miran, yemwe adachereza alendo athu, akukula mwachangu, koma akadali waubwenzi komanso wosavuta.

Maulalo ndi malo abwino kwambiri a data, okhala ndi chitetezo patsogolo komanso odziwa malonda.
RETN ndi anyamata achichepere, okondwa "ochokera ku magalaja" omwe akumanga maukonde akuluakulu komanso malo ang'onoang'ono a data ndipo samadana ndi kuyatsa moto padenga.

Metrotek ndi gulu laling'ono la hardware ndi opanga mapulogalamu a ku Russia, omwe pafupifupi "ndi manja omwewa" amapanga mulu wa zida zoyezera zomwe zimakhala zopambana, ndipo tsopano akulowa mumsika watsopano ndi ntchito yofuna.

Ndipo Laser Center, yomwe imapitilira zokonda za linkmeup, koma ndiye zomwe timakonda. Ndinasiya chidwi chosangalatsa kwambiri komanso kujambula kwa maikolofoni pa chojambulira.
