Izinsuku zokuqala zasehlobo zinhle kakhulu ohambweni lwemfundo oluya eSt.
Sizovakashela i-Miran, i-linxdatacenter, i-RETN ne-Metrotek.

Ngo-5 ekuseni, isiteshi saseMoskovsky, i-KFC, i-Moika embankment, i-Plate, amajuba avela ophahleni, iSt. Isaac's, Field of Mars, i-Yandex drive Capture, futhi nansi - Miran.

U-Miran

Ilebhu yethu eno-Eva, iseva yokusakaza, i-Mikrotik Routeros ebonakalayo, ukusingathwa kwe-linkmeup ngokufinyeleleka kwe-IPv6, futhi manje ukusingathwa kwe-podcast sekuneminyaka eminingana behlala e-Mirana.

Ekungeneni kwe-Miran saqale sabingelelwa imboni ekhiqiza udizili enobukhulu obumangalisayo.

Amasethi amaningi ka-Diesel Generator asemasondo ngenxa yezizathu ezimbili:

• Ukuhamba - kukhona amamojula amaningana e-Mirana aqhele ngamamitha angamakhulu ambalwa. Banamajeneretha abo - kodwa ngeke wazi - kuzomele uwasonge.
• Ukuhamba - akudingi ukuthi zibhaliswe njengezimboni zikagesi ezimile futhi, ngokufanelekile, akukho mibhalo yokuklama edingekayo.

I-DGU Mirana ebusika nasehlobo iqala emizuzwaneni embalwa. Ngalesi sikhathi, yonke isikhungo sedatha sinikwa amandla amabhethri.

Kokubili i-HP yensimbi esimweni sikaMiran kanye nohambo lwaba khona ngenxa kaFedor Rusakov.

Lonke uhambo lwenzeka endaweni ethokomele yasekhaya. Ikhofi ngamakhukhi, ingxoxo mayelana ne-telecoms, mayelana nemvelaphi yenkampani, mayelana nokuthutha amaseva we-vkshechka angamakhulu amabili ukusuka eMoscow kuya eSt. Petersburg ngaphansi kwesembozo sobumnyama. Sahamba ngokukhululeka emabhilidini amabili esikhungo sedatha. Zombili ziyizinguquko zeBrownField ezivela emagcekeni emboni. Kweyokuqala, ephethwe nguMiran, lapho saqala khona nalapho esitezi sesibili sashajwa khona ngemva kokuhamba amahora amane sizungeza iSt. Empeleni sasingekho isitezi sesibili - kwakunamasango amakhulu okuya emuva naphambili. Konke kwahlakazwa, kwakhiwa isitezi sesibili, ukupholisa okusebenzayo, ukunikezwa kwamandla kagesi, uhlelo lokucisha umlilo ngegesi.

Indawo eshisayo yakudala, lapho umoya unikezwa khona ama-air conditioner nangaphansi kwesitezi esiphakanyisiwe endaweni ebandayo evaliwe.

Izintambo zikagesi nazo zifihliwe ngaphansi kwesitezi esiphakanyisiwe.

UMiran akazalwanga njengenkundla yeklayenti elilodwa lehange, kodwa kunalokho wathuthukisa ukunikezwa kwakhe emakethe lapho kunesidingo khona.

Ngesinye isikhathi kwakukhona ibhange elikhulu lapha elinabo bonke onogada abadingekayo kanye nezinhlelo zokulawula ukufinyelela, kodwa selivele liphumile.

Isidingo saqhubeka sikhula, uMiran naye, kwavela isakhiwo sesibili - esesivele sizoqashwa - futhi iBrownField - amamitha angamakhulu amabili ukusuka kwesokuqala. Umgwaqo ugudla uthango lweBolshaya Nevka udlula umuzi kaNobel.

Isakhiwo esisha sakhelwe phezu komgomo we-modular onekhono lokuthutha yonke imojula uma kunezinkinga nomnikazi wendawo. Amabhokisi amabili okuqala athengwa kumkhiqizi, owesithathu wayesevele ehlangene ngokucabangela amaphutha amadala.

Ukwakhiwa kwe-Modular kuvele kunemibi - kuncane kakhulu - umhubhe oshisayo ungama-60 cm - abantu ababili abakwazi ukuhlukana. Futhi okubaluleke kakhulu, izindleko zokuhamba, njengoba kwenzeka ekubalweni kokuqala, zifaniswa nokwakha entsha.

Kodwa zibukeka zizintsha futhi zinemfashini ngaphandle nangaphakathi.

I-NOC yabafana ku-Orthodox Linux, i-Debian ezinzile.

Le nkampani, ngendlela, yathola igama layo ebhodini Lohlelo Lwesimemezelo Esihlanganisiwe Se-Meridian Integrated Recorded (MIRAN) ekushintsheni kocingo lwe-Meridian. Futhi ngemva kwalokho, isikhungo sedatha sabizwa kanjalo.

Banquma ukwakha isikhungo sedatha ngonyaka onzima we-2008.

Kusukela lapho, abafana bebelokhu behlinzeka nge-dedik nensimbi. Imishini ye-opharetha ifakwe emakamelweni akhethekile.

Futhi lokhu kubeka imikhawulo ethile nezici emsebenzini. Isibonelo, ama-racks aqukethe amathuluzi ahlukahlukene kakhulu, kokubili ngokwemishini nangokwezokuxhumana. E-Miran, angizange ngibone u-Arista noMellanox kuphela. Yonke imishini inezidingo ezahlukene zokushisa emhubheni obandayo, ngakho-ke kufanele igcinwe ezingeni eliphansi kakhulu - mayelana ne-20 ° C, okungukuthi, asikho isidingo sokukhuluma nge-PUE ephansi - i-Miran ine-1,5.
Enye i-nuance ngemishado yezinyoka ezitendi. Lapho nje uvumela ozakwabo bangaphandle ukuthi bangene egumbini ngokuxhumana kwabo, bhala ukuthi “ubuhle buhambile.” Akekho onokuhlukile.

Maye, ukwethula izindlela ezicindezelayo lapha kungase kube yingozi kuwe.

Izithombe zakamuva.

Bese uthengisa kusuka etafuleni lethu kuya kwelakho futhi kusuka kweyakho kuya kwelethu. Isixuku sonke sagcwala ematekisini nasema-link.

linxdatacenter

Laba abafana abazimisele, abaphasa labo lesikhashana lize lithi "Izindaba Zokuphepha." Lokhu kuzoba i-leitmotif yalo lonke uhambo.

Ngemuva kwe-gingerbread Miran e-linxdatacenter, uyaqonda ukuthi i-DC yokunethezeka isifikile. Ngosuku lwabo lokuphumula, abantu abangu-4 bahlangana ndawonye, ​​bekhuluma ngokungananazi, bengekho enkabeni yedolobha ukuze batshele abanye abantu abahlanu okungenzeka ukuthi babe ngamakhasimende abo :)

UMaria Svistunova wasihlangabeza futhi wasiyisa etafuleni elikhulu lezingxoxo. Inkulumo encane eyize ngekhofi laseGuatemala bese siyahamba.

Uhambo lusakazwa lapha. UMaxim no-Oleg bayazazi izinto zabo: bazitshela njengoba bezazi: ngokucacile nangentshiseko. Lapho kudingekile, bayagcizelela, futhi lapho kungenjalo, bayadlula. Amahlaya nawo ahleleke kahle, ngakho-ke isikhathi esingaphezu kwamahora amabili sandiza singanakwa.

Ukuziqhenya kwesikhungo sedatha yisikhathi esingu-100% kusukela yethulwa ngo-2011.

Ukuzethemba kuphezulu kangangokuthi akukho ngisho nendawo ebhodini lokuphawula okweshumi.

I-Linx iyisibonelo se-DC ngefomethi yeGreenField. Lesi sakhiwo sakhiwe ngokukhethekile ukuze sibe ne-DC. Ngakho-ke, ukuphakama kophahla, amandla ephansi, okokufaka kwamandla kagesi, ukuphindaphinda kwayo, i-SCS - kufakwe kuphrojekthi futhi kucatshangelwe esigabeni sokwakha.

Ngakho-ke, ngokuzenzakalelayo, phansi kungamelana nokuma kwe-800 kg, kodwa isisindo singandiswa ngokuqhubekayo ngemva kokuqiniswa okwengeziwe. Bathi ama-Oracle racks abiza i-Falcon9 adinga ukwelashwa okukhethekile.

I-DC ngokwayo inikwa amandla ukufakwa kwe-gas-piston, futhi ugesi wedolobha uyinqolobane kuphela. Ngokusho kukaMaxim, lesi kwakuyisinqumo esilungile kakhulu, ngoba ngesikhathi sokucima okudumile kwaseSt. Petersburg, ihhovisi kanye nesikhungo sebhizinisi esiseduze sonakalisiwe, kodwa isikhungo sedatha saqhubeka nokusebenza.

Ijeneretha kadizili lapha ayiseyona i-trailer enamasondo, kodwa isiyigumbi elimile ngokuphelele elinoshimula abakhuphukela phezulu ngaphezu kwendawo.

Isikhathi sokuqalisa asidluli imizuzu emibili, futhi yonke isikhungo sedatha singasebenza kumabhethri cishe ihora. Izinjini zikadizili zingasebenza izinsuku ezi-3 ngaphandle kokugcwalisa uphethiloli.

Kukhona ukuhleleka nokucabangela kukho konke lapha.

Lena, isibonelo, i-Klyuchintsa, lapho amakhasimende esikhungo sedatha angathatha khona okhiye kuma-racks awo esebenzisa izigxivizo zeminwe.

Futhi leli yigumbi lapho amaklayenti engakwazi ukwenza noma yimuphi umsebenzi wobunjiniyela awudingayo, lapho ithuluzi lokugxilisa lilenga odongeni.

Lawa angamashalofu okusetshenziswa kwendawo anakho konke okubalulekile emsebenzini wansuku zonke:

Ihlale ishajiwe futhi ilungele ukuhamba.

Ikepisi le-baseball le-hiphopper efisayo esithombeni esingenhla lilondoloze ikhanda lomuntu ongaphezu koyedwa. Kunzima njengesigqoko sokuzivikela semvelo-into engcono kakhulu ongayenza ukukhuphuka ngaphansi kwemitha eyodwa nengxenye ephakanyisiwe phansi, lapho, cha, cha, kukhona insimbi ebukhali ephumela ngaphandle.

Eqinisweni abasebenzi kusukela ekusebenzeni:

Le divayisi engakholeki iyigeyiji yengcindezi ehlukile.

Yenzelwe ukuxazulula inkinga elula - ukugcina umehluko wengcindezi phakathi kwephaseji negumbi lomshini. Isibonelo, ukuze iphakame kancane ngaphakathi futhi lapho umnyango uvuleka, uthuli alundizeli ngaphakathi, kodwa kunalokho lundiza lusuke emnyango.

Isistimu yokucisha umlilo nayo iyigesi - uma kwenzeka kuba nenkathazo, igesi isusa umoya-mpilo futhi inqande ukusha.

Abafana abangathí sina futhi abangathí sina kuphela abanezizathu ze-paranoia yobukhulu be-Ararati abama kuzixhumanisi.

Ama-Grille kanye nesistimu yokulawula ukufinyelela ehlukene kusukela esikhungweni sedatha kuyisiqalo nje.

Lapho abantu ababili beza ukuze baxazulule inkinga noma benze ukuxhumana okusha - omunye ngokhiye wezinto ezibonakalayo, omunye nge-electronic - lokhu kuba mnandi kakhulu. Futhi lapho umcwaningi we-bespectacled efika evela kuklayenti, ehla ngaphansi kwesitezi esiphakanyisiwe, ehlukanisa amashidi amabili emigoqo futhi ethi ikhanda lomntwana lizongena lapha, uyaqonda ukuthi umuntu uye wabona izinto ezithakazelisayo empilweni yakhe.

Kwakukhona izimo ezihlekisayo lapho, lapho uklama ikheji, becabangela konke okusemandleni, zonke izinhlelo zokuphepha, zonke izilinganiso ezikuvumela ukuthi ungenise i-rack futhi ubeke imishini kuyo, kodwa ngandlela-thile abazange bacabange ngobukhulu be-rack. onjiniyela abazosebenza nayo. Kodwa azilingani phakathi kwekheji nokuma kungaba ngaphambili noma kuphrofayili.

Ukube bengiyi-FSB, bengizofaka i-hardware yami ku-linx :)

Ngemva kohambo, sahlala isikhathi eside, sixoxa kamnandi nge-pizza.
Ukusuka kulo mkhakha wokuphepha nokuhleleka sathuthela e-RETN.

I-RETN

Laba bafana kudala sazana nabo. Ngakho-ke, akumangazi ukuthi ekugcineni sabuthana ophahleni lwabo sizokosa inyama futhi sixoxe izindaba.

Nathi sesike saya kubo, nakuba ngingacabangi ukuthi sikutshele ngakho. Ngonyaka odlule, izinhlelo zokushaqa uphahla lwaseSt. Petersburg zabhuntsha ngenxa yeFifa.

I-RETN empeleni iyi-opharetha yomgogodla omkhulu kunawo wonke onefayibha emhlabeni wonke. Iwebhu yabo izoba umona wanoma yisiphi isicabucabu.

Futhi i-DC ku-Obvodny iphrojekthi yasekhaya yomphefumulo othole indawo yayo emakethe ekhulayo. Yilapho kungena khona labo abadinga ukuxhumana okuqinile nomhlaba kanye nokufinyelela kwabanye opharetha bendawo.

Isibonelo, i-RETN iqukethe i-CDN ye-Netflix.

Ngamangala lapho ngizwa ukuthi i-node ngayinye yayisayinwe ngesandla ngomusho.
Futhi lawa mabhokisi eholide ashaywa emadolobheni ahlukene kuma-POP e-RETN (futhi, ngokusobala, hhayi wona kuphela), alethela “I-Black Mirror” kanye “Ne-Peaky Blinders” kuwe ngokushesha okukhulu.

Kukhona futhi i-CDN ye-Google kanye nenqwaba yama-opharetha, kokubili wendawo kanye nombuso.

I-RETN inamajeneretha edizili amabili amancane (uma kuqhathaniswa neka-Miranov) kanye nemoto enamathini okuya egalaji likaphethiloli eduze kwesakhiwo. Kuzwakala kufana nebhizinisi lomndeni.

Nokho, izingxoxo zakusihlwa ophahleni zisilethe ezingeni lokuthi i-RETN izosinika ibhokisi elibonakalayo lesayithi eliyisipele lokusingatha amaphodikasti nezithombe.
I-World guys, isikhungo sedatha yesibani esiphezulu, inethiwekhi emangalisa ngesilinganiso sayo.

Kwabanye, lolu suku lwaphela ngomqhudelwano we-duke nukem, kwabanye ngokulala okudala kulindwe ehhotela.

Ngosuku olulandelayo asizange sibe nezinhlelo eziningi: I-Metrotek ne-podcast bukhoma - isixhumanisi se-IRL.

I-Metrotek

Enyangeni edlule sivakashele i-podcast ye-telecom weza UMisha Sokolov noDenis Gabidullin abavela ku-STC Metrotek basika i-Plumspace, futhi sixoxe ngokuthi iyini i-Smart SFP. Futhi manje sakwazi ukubathinta bephila.

UDenis, owavakashela ihhovisi laseMetrotek laseSt. Petersburg (okuwukuthi, elingazange lishintshe kusukela ekuhambeleni kwethu kokugcina kubo), empeleni wanikeza elinye lamasampula khona kanye emnyango.
Ngiqale ngamangala indlela eyakhiwe ngayo - sengathi iqoshwe esikrufuni esingu-32mm ngejigsaw nefayela.

Kuvele ukuthi umzimba we-prototype wawuyi-3D ephrintiwe kusuka kumpushana wensimbi, njengoba kungabonakala endaweni embi. Ezinye - lezo ezilungele uchungechunge - zihlelekile kahle.

Kodwa ngokuvamile, uma ubabheka, uyamangala ukuthi bakwazi kanjani ukufihla ubuchopho obuningi esimweni esicishe sibe yizinga elijwayelekile.

Ngikweluleka ukuthi ulalele i-podcast emayelana no-Rosa, u-Tozu nodadewabo u-Boza. Kuvele kuthakazelisa ukunambitheka kwami.

Umklamo wehhovisi ujwayelekile ngangokunokwenzeka. Amahhovisi amancane angama-rectangular, anwetshiwe ngasefasiteleni, amnyama impela, okwakucindezela kancane. Kodwa umkhathi, naphezu kosuku lokuphumula, wawufana nomsebenzi.

Umklamo awushintshile eminyakeni emibili. Ngijabule ngamanye amaphosta namabhodi.

Sihambe emakamelweni amaningana: I-R&D, onjiniyela besistimu, ochwepheshe be-FPGA, abaphethwe ezandleni zethu izinhlobo ezahlukene ze-SFP, abahleli bezinhlelo, babone imodeli yokuqala lapho i-Smart yasuswa khona ku-SFP ngocingo - enye yezivivinyo zokuqala - kunalokho, a Ubufakazi bomqondo bokuthi iyasebenza nhlobo.

Bathi amanye amakhasimende akuthola kulula ukuba nomsila onjalo uphume ensimbini yawo.
Inhloso yokuqala ngqa eminyakeni emibili eyedlule bekuwukuhlanganisa i-SFP evamile yokubona okungenani ezodlulisa isignali.

Babe sebehlanganisa ngokwehlukana ingxenye ye-Smart ne-SFP yomunye umuntu (entanjeni nje) ukuze baqiniseke ukuthi bayakwazi ukuhlanganisa ama-chips.

I-Metrotek yenze umsebenzi omuhle kakhulu. Cabanga nje ukuthi eminyakeni emi-2 bahlanganisa imojula ye-optical esebenza ngokugcwele engahlanganisa, i-telemetry, iseva yesikhathi esiqondile, kanye nesiguquli esibonakalayo.

Futhi ngesikhathi esifanayo, lungisa iphutha ekupheleleni (yize lokhu kusazohlolwa ngokuhamba kwesikhathi) ukusebenza okuyisisekelo kokudluliswa kwesignali. Akufanele kube khona ukuncishiswa, akufanele kube namaconsi angavamile ngenxa yephutha le-SFP. Futhi akufanele kushise, naphezu kwephakethe lama-ASIC, ama-FPGA nama-CPU ngaphakathi.
Qina!

Qedela isistimu yekhompyutha:

• CPU: NXP i.MX6 ARM kufika ku-900 MHz
• I-FPGA: I-Lattice ECP5 ifika ku-85K LUTs
• I-RAM: DDR3 kufika ku-1 GB

UDenis waphawula ukuthi inkampani iyazijwayeza futhi ikhuthaza ukushintshana ngolwazi nolwazi. Ngabe sengicabanga: “Kungaba ngenye indlela ngempela? 0_o". - Yebo, ngokuvamile abantu beza kubo abathi, endaweni ababesebenza kuyo ngaphambili, badla amajusi abo, babengakhulumisani, benza umsebenzi ophindwe kabili noma kathathu futhi ngokuvamile bagwema imizamo yokuxhumana.

Ngase ngikhumbula ukuthi, ngokuvamile, eminyakeni emibili edlule ngangisebenza enkampanini yamazwe ngamazwe, evinjelwe kakhulu, lapho izingqungquthela zazivinjelwe futhi ukushintshaniswa kolwazi kwakungekho njengekilasi. Futhi ngangingomunye wabavangeli bemihlangano yokushintshisana yamasonto onke eyayibonakala isindisa onjiniyela abanesizungu ezindaweni ezikude.

Ngokuvamile, i-Metrotek yenza njalo ukuqeqeshwa kwangaphakathi nezinkulumo, yingakho zinhle.

Sabe sesiyiswa endaweni yokusebenzela yokufaka emangalisayo. Kungakhathaliseki ukuthi ngibavakashela kangaki, kubonakala sengathi injabulo yami yobuntwana ayipheli.

I-Metrotek inemishini yokunyathelisa emabhodini esekethe khona ehhovisi.

I-stencil yokufaka ama-solder pellets, iphrinta yezingxenye ze-SMD (angikwazi ukukubiza ngokuthi yini enye), isitofu esincane sokubhaka amabhodi wesifunda kanye neziteshi zokusebenza eziseduze zokufakwa ngesandla.

Ngamangala lapho ngithola ukuthi ama-microchip anamakhulu emilenze nawo adayiswa ngesandla. UDenis uthi abafana babo bathengisa izingxenye ezincane ngokunemba okumangalisayo nesivinini, futhi ngezinye izikhathi asikho isidingo sokusebenzisa umshini we-shaitan - umuntu uzokwenza ngokushesha.

Siqambe umugqa wokukhiqiza ngokuthi iMetrotek Eltex-Verilight phakathi kwethu, ngenxa yohambo lwakamuva oluya kubo.

Ngaphezu kwalokho, ihhovisi linephrinta ye-3D nomshini wokugaya wezidingo zangaphakathi, nokho, owawuvele usetshenziselwe ukubhala izindondo ngonyaka odlule. Ukwakhiwa Kwezinxushunxushu.

Ukusuka lapho saya e-Krang Pizza, emangalisa ngokuqukethwe kwayo kwemibono, lapho ithimba eligcwele le-linkmeup ligwinye ibhega ye-pizza eyayiguquguqukayo ngobukhulu nencazelo yayo futhi yathuthela ehhovisi lezinketho ze-IQ, lapho saqopha khona isiqephu sokuqala. isixhumanisi se-IRL.

Ngosuku olulandelayo, siphinde sabheka Isikhungo Se-Laser ethiphu evela eMammoth, lapho sathola khona injabulo yobuchwepheshe kanye nokuvuvukala okuncane kokuhaha, kodwa lokho kuzoba indaba ehlukile.

Sengiphetha, ngithanda ukusho ukuthi zonke izinkambo nemihlangano ihluke kakhulu, kokubili ngezinga lezenzo kanye nokugxilwa kwayo.

U-Miran, owasingatha ngokufudumele ukusingathwa kwethu, ukhula ngokushesha, kodwa usenobungane futhi ulula.

Izixhumanisi ziyisikhungo sedatha esipholile ngempela, esinokuphepha okuphambili nabathengisi abanolwazi.
I-RETN abafana abancane, abajabule "abavela emagaraji" abakha inethiwekhi enkulu kanye nesikhungo esincane sedatha futhi abakwenqabeli ukubasa umlilo ophahleni.

I-Metrotek iyiqembu elincane uma kuqhathaniswa labathuthukisi bezingxenyekazi zekhompyutha baseRussia nabathuthukisi bezinhlelo zesofthiwe, cishe “ngazo kanye lezi zandla” lenza inqwaba yezinto zokulinganisa ezingaphezu kokuncintisana, futhi manje lingena emakethe entsha ngomsebenzi wokuvelela.

Futhi Isikhungo Se-Laser, esidlulela ngale kwezithakazelo ze-linkmeup, kodwa into esizithandayo. Ngishiye umbono omnandi kakhulu kanye nokuqoshwa kombhobho kusiqophamazwi.
