Mazuva ekutanga ezhizha akanaka kune rwendo rwekudzidzisa kuSt.
Tichashanyira Miran, linxdatacenter, RETN neMetrotek.

5 am, Moskovsky station, KFC, Moika embankment, Plate, njiva kubva pamatenga, St. Isaac's, Munda weMars, Yandex drive Capture, uye heino - Miran.

Miran

Lab yedu naEva, sevha yekutepfenyura, chaiyo Mikrotik Routeros, linkmeup hosting ine IPv6 kuwanikwa, uye ikozvino podcast hosting vanga vachigara muMirana kwemakore akati wandei izvozvi.

Pamukova weMiran takatanga kukwaziswa nejenareta redhiziri rinoyevedza.

Mazhinji Diesel Jenareta Sets ari pamavhiri nekuda kwezvikonzero zviviri:

• Mobility - kune akati wandei Mirana modules mazana mashoma emamita kure. Vane majenareta avo - asi haumboziva - unozoamisa.
• Mobility - haidi kunyoreswa sezvimisikidzo zvemagetsi emagetsi uye, nekudaro, hapana magwaro ekugadzira anodiwa.

DGU Mirana munguva yechando uye zhizha inotanga mumasekondi mashoma. Munguva ino, iyo data data yese inofambiswa nemabhatiri.

Ose ari maviri iron HP mune chimiro chaMiran uye rwendo rwakave rwunogoneka nekuda kwaFedor Rusakov.

Rwendo rwese rwakaitika mumhepo inotonhorera yepamba. Kofi nemakuki, hurukuro pamusoro pefoni, nezvekwakabva kambani, pamusoro pekutakura mazana maviri evhavha vkshechka kubva kuMoscow kuenda kuSt. Petersburg pasi pechifukidziro cherima. Takafamba takatandara tichipfuura nepakati pezvivakwa zviviri zve data center. Ose ari BrownField shanduko kubva kufekitori nzvimbo. Mune yekutanga, yaive naMiran, kwatakatanga uye uko pauriri hwechipiri takachajazve mushure mekufamba kwemaawa mana tichitenderera St. Chaizvoizvo pakanga pasina huriri hwechipiri - pakanga paine magedhi makuru ekudzoka nekudzoka. Zvese zvakabviswa, pauriri hwechipiri hwakavakwa, kutonhora kunoshanda, simba risingaperi, gasi rekudzima moto system.

Mukoto unopisa wemhando yepamusoro, unobva panopinzwa mhepo kune maairconditioner uye pasi peuriri hwakasimudzwa mukamukana kanotonhora kakavharwa.

Matambo emagetsi akavanzwawo pasi pevhu rakasimudzwa.

Miran haana kuzvarwa sepuratifomu yeimwe anchor mutengi, asi akagadzira zvakarongeka kupa kwayo mumusika uko kune kudiwa.

Pane imwe nguva pakanga paine bhangi hombe pano nevarindi vese vanodiwa uye magadzirirwo ekutonga, asi yakatotama.

Kudiwa kwakaramba kuchikura, Miran zvakare, chivakwa chechipiri chakaonekwa - chatove kurojeswa - zvakare BrownField - mazana maviri emamita kubva kune yekutanga. Mugwagwa unofamba uchitevedza Bolshaya Nevka embankment kupfuura imba yaNobel.

Ichi chivakwa chitsva chakavakirwa pane modular musimboti nekugona kutakura iyo module yese kana paine matambudziko nemuridzi wemba. Mabhokisi maviri ekutanga akatengwa kubva kumugadziri, yechitatu yakanga yatounganidzwa ichifunga nezvezvikanganiso zvekare.

Modular architecture yakave nekuipa - iwo akatetepa - iyo inopisa corridor ndeye 60 cm - vanhu vaviri havagone kupatsanura. Uye zvinonyanya kukosha, mari yekufambisa, sezvazvakazoitika pakuverenga kwekutanga, inofananidzwa nekuvaka imwe itsva.

Asi ivo vanotaridzika kutsva uye fashoni zvese kunze nemukati.

NOC yevakomana paOrthodox Linux, yakagadzikana Debian.

Iyo kambani, nenzira, yakawana zita rayo kubva kuMeridian Yakabatanidzwa Yakarekodhwa Chiziviso (MIRAN) System board mune Meridian nhare switch. Uye mushure meizvozvo, iyo data data yakanzi iyo.

Vakasarudza kuvaka nzvimbo yedata mugore rakaoma re2008.

Kubva ipapo, vakomana vanga vachipa dedik nebhero. Operator midziyo yakaiswa mumakamuri anokosha.

Uye izvi zvinoisa zvimwe zvirambidzo uye maficha pabasa. Semuyenzaniso, maraki ane midziyo yakasiyana-siyana, zvese maererano nemichina uye maererano netiweki. MuMiran, ini handina kungoona Arista naMellanox. Midziyo yese ine zvinodiwa zvakasiyana zvekupisa mukoridho inotonhora, saka inofanirwa kuchengetedzwa padanho rakaderera - anenge 20 ° C, ndiko kuti, hapana chikonzero chekutaura nezve yakaderera PUE - Miran ane iyo 1,5.
Imwe nuance ndeye michato yenyoka mumastand. Paunongobvumira shamwari dzekunze kuti dzipinde mukamuri nehukama hwavo, nyora kuti "runako rwaenda." Hapana anosarudzika.

Maiwe, kuunza draconian matanho pano kungave kukukuvadza.

Uye wobva watengesa kubva patafura yedu kuenda kune yako uye kubva kune yako kune yedu. Chaunga chese chakazara mumataxi uye mumalink.

linxdatacenter

Ava vakomana vakakomba, vane pfumo yechinguvana inototi "Security Matters." Iyi ndiyo ichava iyo leitmotif yerwendo rwese.

Mushure megingerbread Miran pa linxdatacenter, iwe unonzwisisa kuti yakasarudzika DC yasvika. Pazuva ravo rekuzorora, vanhu vana vakaungana, vachitaura pachena, kwete pakati peguta kuti vataure nezvavo kune vamwe vanhu vashanu vasingafungire kuve vatengi vavo :)

Maria Svistunova akasangana nesu ndokuenda nesu kutafura hombe yekutaurirana. Hurukuro shoma shoma pamusoro pekofi yeGuatemalan tobva taenda.

Excursions pano ari parukova. Maxim naOleg vanoziva zvinhu zvavo: vanozvitaurira nenzira yakasakara: zvakajeka uye nechido. Pazvinenge zvakakodzera, vanosimbisa, uye pazvisina, vanonzvenga. Pfungwa yekuseka zvakare iri muhurongwa hwakakwana, saka anopfuura maawa maviri akabhururuka asingaonekwe.

Kudada kwenzvimbo yedata ndeye 100% nguva kubva payakatangwa muna 2011.

Chivimbo chakakwirira zvekuti hapana kana nzvimbo pabhodhi rezvibodzwa zvegumi.

Linx muenzaniso weDC muGreenField fomati. Chivako ichi chakanyatsovakwa kuti chigare DC. Naizvozvo, kureba kwedenga, kusimba kwepasi, magetsi ekushandisa, kuregererwa kwayo, SCS - yakabatanidzwa muchirongwa ichi uye yakaverengerwa padanho rekuvaka.

Saka, nekusingaperi, pasi inogona kumira kumira kwe800 kg, asi uremu hunogona kuwedzerwa mberi mushure mekuwedzera kusimbiswa. Vanoti maraki eOracle anodhura Falcon9 anoda kurapwa kwakakosha.

Iyo DC pachayo inofambiswa negasi-piston kuisirwa, uye magetsi emuguta inzvimbo yekuchengetera chete. Maererano naMaxim, ichi chaiva chisarudzo chakarurama kwazvo, nokuti panguva yakakurumbira yeSt.

Jenareta redhiziri pano haisisiri turera pamavhiri, asi imba yakamira yakazara ine machimuni anokwira kumusoro pamusoro penzvimbo.

Nguva yekutanga haipfuuri maminetsi maviri, uye iyo data data yese inogona kushanda pamabhatiri kweinenge awa. Diesel injini dzinogona kushanda kwemazuva matatu pasina kuwedzera mafuta.

Pane kurongeka uye kufunga mune zvese pano.

Izvi ndizvo, semuenzaniso, Klyuchintsa, uko vatengi venzvimbo yedata vanogona kutora makiyi kumaraki avo vachishandisa zvigunwe zvavo.

Uye ino ikamuri umo vatengi vanogona kuita chero basa reinjiniya ravanoda, iro rinosungirirwa mudziyo wesimbi pamadziro.

Aya atove masherufu ekushandiswa munharaunda ane zvese zvakakosha kubasa remazuva ese:

Inogara yakachajwa uye yakagadzirira kuenda.

Iyo baseball cap yeanoshuvira hiphopper pamufananidzo uri pamusoro yakachengetedza musoro weanopfuura munhu mumwechete. Zvakaoma sengowani yechisikigo - chinhu chakanakisa kuita kukwira pasi pemita imwe nehafu yakasimudzwa pasi, uko, kwete, kwete, imwe simbi inopinza inonamira kunze.

Chaizvoizvo vashandi kubva kushanda:

Ichi chishamiso chishandiso chinosiyanisa kudzvanywa gauge.

Yakagadzirirwa kugadzirisa dambudziko riri nyore - kuchengetedza musiyano wekumanikidza pakati pekoridhi nekamuri yemuchina. Semuenzaniso, kuitira kuti iwedzere zvishoma mukati uye kana musuwo wakazaruka, huruva haibhururuke mukati, asi inobhururuka kubva pamusuwo.

Iyo yekudzima moto system igasi zvakare - kana paine dambudziko, gasi rinobvisa okisijeni uye rinomisa kupisa.

Vakomana chete vakakomba uye vakakomba kwazvo vane zvikonzero zveparanoia saizi yeArarati vanomira mumalink.

Grilles uye yakaparadzana yekuwana control system kubva kudhata data ingori kutanga.

Kana vanhu vaviri vauya kuzogadzirisa dambudziko kana kuita shanduko nyowani - imwe ine kiyi yezvinhu, imwe ine yemagetsi - izvi zvinowedzera kunakidza. Uye kana muongorori wekutarisa anosvika kubva kune mutengi, anodzika pasi pevhu rakasimudzwa, anokwevera mapepa maviri emapuranga uye anotaura kuti musoro wemwana uchakwana pano, iwe unonzwisisa kuti munhu akaona zvinhu zvinonakidza muupenyu hwake.

Paive nemamiriro ezvinhu anosetsa apo, pakugadzira keji, vaifunga nezve zvese zvaigoneka, ese ekuchengetedza masisitimu, zviyero zvese zvinokutendera kuti utore kunze rack uye kuisa midziyo mairi, asi neimwe nzira havana kufunga nezvehukuru hwe. mainjiniya vaizoshanda nayo. Asi ivo havakwane pakati pekeji uye yekumira kungave kumberi kana muprofile.

Dai ndaiva FSB, ndaizoisa hardware yangu mu linx :)

Mushure merwendo, takagara kwenguva yakati rebei, tichikurukura nemoyo wese pamusoro pepizza.
Kubva munzvimbo ino yekuchengetedza uye kurongeka takatamira kuRETN.

RETN

Vakomana ava takavaziva kwenguva refu. Naizvozvo, hazvishamise kuti takazoungana padenga ravo kuti tigogocha uye kutaura nyaya.

Takamboendawo kwavari, kunyange ndisingafungi kuti takakuudzai nezvazvo. Gore rapera, zvirongwa zvekubvuta matenga eSt. Petersburg zvakakundikana nekuda kweFifa.

RETN ndiyo chaiyo yakakura musana mushandisi ine fiber pasirese. Dandemutande ravo richava godo chero mhungu.

Uye iyo DC paObvodny ipurojekiti yeimba yemweya iyo yakawana niche yayo mumusika uri kukura. Apa ndipo panopinda avo vanoda kubatana kwakasimba nenyika uye kuwana kune vamwe vashandisi venzvimbo.

Semuenzaniso, RETN ine Netflix's CDN.

Ndakashamisika kuziva kuti imwe neimwe yenode yavo yakasainwa neruoko nemutsara.
Uye aya mabhokisi ezororo ari kurohwa mumaguta akasiyana paRETN's POPs (uye, zviri pachena, kwete chete), kuendesa "Black Mirror" uye "Peaky Blinders" kwauri nekukurumidza sezvinobvira.

Kune zvakare Google's CDN uye boka revashandisi, vese vemunharaunda nemubatanidzwa.

RETN ine madiki maviri madiki (achienzaniswa naMiranov) majenereta edhiziri uye mota ine magaba ekuenda kuchiteshi chepeturu chiri pedyo nechivako. Inonzwika kunge bhizinesi remhuri.

Zvakanaka, nhaurirano dzemanheru padenga dzakatisvitsa padanho rekuti RETN yaizotipa bhokisi chairo resaiti yekuchengetedza yekutambira podcasts nemifananidzo.
World guys, super-lamp data center, network inoshamisa nechiyero chayo.

Kune vamwe, zuva iri rakapera nemakwikwi e duke nukem, kune vamwe vaine hope dzakamirirwa kwenguva refu muhotera.

Zuva rakatevera takanga tisina zvirongwa zvakawanda: Metrotek uye podcast live - linkmeup IRL.

Metrotek

Mwedzi wapfuura takashanyira telecom podcast akauya Misha Sokolov naDenis Gabidullin kubva kuSTC Metrotek slash Plumspace, uye takakurukura kuti Smart SFP chii. Uye zvino takakwanisa kuvabata vari vapenyu.

Denis, uyo akashanya hofisi yeSt. Petersburg yeMetrotek (iyo, nenzira, isina kuchinja kubva pashanyo yedu yokupedzisira kwavari), chaizvoizvo akagovera mumwe wemienzaniso yacho pasuo chaipo.
Pakutanga ndakashamiswa nehutsinye hwayakaitwa - sekunge yakanga yavezwa kubva mu 32mm wrench ine jigsaw uye faira.

Zvakazoitika kuti mutumbi weiyo prototype wakadhindwa 3D kubva muupfu hwesimbi, sezvinoonekwa kubva kune yakaoma pamusoro. Vamwe - avo vakagadzirira kutevedzana - vari muhurongwa hwakakwana.

Asi kazhinji, uchivatarisa, unoshamiswa kuti vakakwanisa sei kuvanza huropi hwakawanda mune imwe nyaya yakajairwa.

Ndinokupa zano kuti uteerere podcast nezve Rosa, Tozu uye hanzvadzi yavo Boza. Zvakazonakidza pakuravira kwangu.

Dhizaini yehofisi yakajairika sezvinobvira. Mahofisi madiki ane rectangular, akatambanudzwa akananga kuhwindo, akasviba zvakanyanya, izvo zvaiti dzvanyiriri. Asi mamiriro ekunze, kunyangwe zuva rekuzorora, aive nebasa.

Iyo yakagadzirwa haina kuchinja mumakore maviri. Ndakafadzwa nemamwe mapepa nemabhodhi.

Takafamba nemakamuri akati wandei: R&D, mainjiniya ehurongwa, nyanzvi dzeFPGA, dzakabatwa mumaoko edu marudzi akasiyana eSFP, vagadziri vepurogiramu, vakaona muenzaniso wekutanga umo Smart yakabviswa kubva kuSFP pawaya - chimwe chekuyedza kwekutanga - pane kudaro, a. Uchapupu hwePfungwa kuti inoshanda zvachose.

Vanoti mamwe makasitoma anotoona zvakakodzera kuti muswe wakadaro ubude musimbi yavo.
Chinangwa chekutanga makore maviri apfuura kwaive kuunganidza yakajairwa yekuona SFP iyo yaizosvitsa chiratidzo.

Ipapo vakaparadzana vakaunganidza chikamu cheSmart neSFP yemumwe munhu (patambo chete) kuti vave nechokwadi chekuti vaikwanisa kuunganidza machipisi.

Metrotek yakaita basa guru. Chimbofunga kuti mumakore maviri vakaunganidza yakazara inoshanda optical module inogona kuvharidzira, telemetry, chaiyo nguva sevha, uye chinoshandura chinoshandura.

Uye panguva imwe chete, debug kusvika pakukwana (kunyangwe izvi zvichiramba zvichiyedzwa nenguva) iyo yekutanga mashandiro ekufambisa kwemasaini. Hakufanirwe kuve neattenuation, hapafanirwe kunge paine isingawanzo madonhwe nekuda kwekukanganisa kweSFP. Uye haifanirwe kupisa, kunyangwe paki yeASICs, FPGAs uye CPUs mukati.
Bravo!

Computing system yakakwana:

• CPU: NXP i.MX6 ARM kusvika 900 MHz
• FPGA: Lattice ECP5 kusvika ku85K LUTs
• RAM: DDR3 kusvika ku1 GB

Denis akacherechedza kuti kambani inodzidzira uye inokurudzira kuchinjana kweruzivo uye ruzivo. Uye ipapo ndakafunga: "Zvingave neimwe nzira here? 0_o". - Hongu, kazhinji vanhu vanouya kwavari avo, panzvimbo yavo yekare yebasa, vakabika mujusi yavo pachavo, vasina kutaurirana, vakaita basa rakapetwa nekatatu uye kazhinji vaidzivisa kuedza kutaurirana.

Uye ipapo ndakarangarira kuti, kazhinji, makore anopfuura maviri apfuura ndakashanda mune imwe nyika, kambani yakarambidzwa zvikuru, uko misangano yakarambidzwa uye kuchinjana ruzivo kwakanga kusipo sekirasi. Uye ndakanga ndiri mumwe wevaevhangeri vemisangano yevhiki nevhiki yokutsinhana iyo yairatidzika kuva inoponesa mainjiniya ari oga munzvimbo dziri kure.

Kazhinji, Metrotek inogara ichiitisa kudzidziswa kwemukati uye hurukuro, ndicho chikonzero ivo vakanaka.

Uye ipapo takaendeswa kumusangano wekugadzira unoshamisa. Pasinei nokuti ndinovashanyira kakawanda sei, zvinoita sokuti mufaro wangu wouduku hauperi.

Metrotek ine michina yekudhinda pamabhodhi edunhu muhofisi chaimo.

Stencil yekushandisa solder pellets, printer yeSMD components (ini handikwanise kuidana chero chimwe chinhu), chitofu chidiki chekubikira mabhodhi edunhu uye zviteshi zvebasa zviri pedyo zvekugadzika nemaoko.

Chakandishamisa ndechekuti ndakaziva kuti mamicrochips ane mazana emakumbo anotengeswa nemaoko. Denis anoti vakomana vavo vanotengesa zvikamu zvidiki nekushamisa kunoshamisa uye nekukurumidza, uye dzimwe nguva hapana chikonzero chekumhanyisa shaitan muchina - munhu anozviita nekukurumidza.

Isu takatumidza mutsetse wekugadzira Metrotek Eltex-Verilight pakati pedu, mushure merwendo ruchangopfuura kwavari.

Pamusoro pezvo, hofisi iyi ine 3D printer uye muchina wekugaya wezvido zvemukati, izvo, zvisinei, zvakatoshandiswa kunyora menduru dzegore rapfuura. Chaos Construction.

Kubva ipapo takaenda kuKrang Pizza, inoshamisa muzvinyorwa zvayo, uko timu izere yelinkmeup yakamedza burger yepizza yaive mutant muhukuru uye zvinoreva uye yakatamira kuIQ sarudzo hofisi, kwatakanyora chikamu chekutanga. linkmeup IRL.

Zuva rakatevera, isu takatarisawo muLaser Center pane muromo kubva kuMammoth, kwatakaona tekinoroji ecstasy uye kushoma kuzvimba kwemakaro, asi iyo ichave iri nyaya yakaparadzana.

Mukupedzisa, ndinoda kutaura kuti mafambiro ese uye misangano yakave yakasiyana kwazvo, muhukuru hwechiito uye mukutarisisa.

Miran, uyo akagamuchira kugamuchira kwedu nemutsa, ari kukura nekukurumidza, asi achiri neushamwari uye ari nyore.

Links inzvimbo inotonhorera yedata, ine chengetedzo kumberi uye vatengesi vane ruzivo.
RETN vakomana vadiki, vanofara "kubva kumagaraji" vari kuvaka giant network uye ichiri diki data data uye havashoreki kuvaka moto padenga.

Metrotek ichikwata chidiki cheRussia hardware uye vanogadzira software, iyo inenge "nemaoko chaiwo aya" inoita murwi wemichina yekuyera iyo inopfuura yemakwikwi, uye ikozvino inopinda mumusika mutsva nebasa rekuda chinzvimbo.

Uye iyo Laser Center, iyo inodarika zvido zvelinkmeup, asi ndicho chinhu chatinoda isu pachedu. Ndakasiya fungidziro yakanaka kwazvo uye kunyorwa kwemaikorofoni parekodha.
