Maitiro ekuvandudza network michina mubhizinesi hombe pasina kumisa kugadzirwa? Anotaura nezve purojekiti yakakura mu "open heart surgery" mode Linxdatacenter maneja maneja weprojekiti Oleg Fedorov.
Mumakore mashoma apfuura, takaona kuwedzera kwevatengi kudiwa kwemasevhisi ane chekuita netiweki chikamu cheiyo IT zvivakwa. Iko kudikanwa kwekubatana kweIT masisitimu, masevhisi, maapplication, kutarisa uye kushanda kwebhizinesi manejimendi mabasa munenge chero nharaunda iri kumanikidza makambani nhasi kubhadhara yakawedzera kutarisisa kune network.
Huwandu hwezvikumbiro hunobva pakuvimbisa kushivirira kwetiweki kusvika pakugadzira uye kutonga mutengi anozvimiririra sisitimu nekutenga block yeIP kero, kumisikidza maprotocol uye kutonga traffic zvinoenderana nehurongwa hwesangano.
Kune zvakare kuwedzera kuri kuda kwemhinduro dzakakwana dzekuvaka nekuchengetedza network network, kunyanya kubva kune vatengi vane network network iri kugadzirwa kubva kutanga kana isingachashandi, inoda shanduko yakakomba.
Maitiro aya akabatana nenguva yekuvandudza uye kuoma kweLinxdatacenter's own network network. Isu takawedzera iyo geography yekuvapo kwedu muEurope nekubatanidza kune nzvimbo dziri kure, izvo zvaidawo kuvandudza network network.
Iyo kambani yakatanga sevhisi nyowani yevatengi, Network-se-a-Service: isu tinotarisira matambudziko ese evatengi 'network, tichivabvumira kuti vatarise bhizinesi ravo rekutanga.
Muzhizha ra2020, chirongwa chikuru chekutanga munzira iyi chakapedzwa, chandinoda kutaura nezvacho.
Pakutanga
Imba yakakura yeindasitiri yakatendeukira kwatiri kuti tigadzirise iyo network chikamu chezvivakwa kune rimwe remabhizinesi ayo. Zvaive zvakafanira kutsiva midziyo yekare nemidziyo mitsva, kusanganisira network core.
Yekupedzisira michina yekuvandudza mubhizinesi yakaitika makore angangoita gumi apfuura. Iwo manejimendi matsva ebhizinesi akafunga kuvandudza kubatana, kutanga nekuvandudza zvivakwa padanho rekutanga, remuviri.
Iyo purojekiti yakakamurwa kuita zvikamu zviviri: kukwidziridzwa kweserver park uye network zvishandiso. Isu takanga tine mutoro wechikamu chechipiri.
Zvinodiwa zvekutanga zvebasa zvinosanganisira kudzikisira nguva yekugadzira bhizinesi mitsara panguva yekuita basa (uye mune dzimwe nzvimbo, kubvisa zvachose nguva yekudzikira). Chero kumira kunoreva kurasikirwa kwemari kwakananga kune mutengi, izvo zvaisafanirwa kunge zvakaitika chero mamiriro ezvinhu. Nekuda kweiyo nzvimbo yekushanda modhi 24x7x365, pamwe nekufunga kusavapo kwese kwenguva yakarongwa yekudzika mukuita kwebhizinesi, takapihwa basa rekunyatso kuvhiya moyo wakavhurika. Ichi chakava chinhu chikuru chinosiyanisa chirongwa.
Enda
Basa rakarongwa maererano nemusimboti wekufamba kubva kunetiweki node dziri kure nepakati kuenda kune dziri padyo, pamwe nekubva kune izvo zvishoma zvinofurira basa rekugadzira mitsetse kune avo vanopesvedzera basa iri.
Semuenzaniso, kana tikatora network node mudhipatimendi rekutengesa, ipapo kukanganisa kwekutaurirana semugumisiro webasa mudhipatimendi iri hakuzokanganisa kugadzirwa nenzira ipi zvayo. Panguva imwecheteyo, chiitiko chakadaro chichatibatsira, semugadziri, kutarisa kururamisa kwemaitiro akasarudzwa ekushanda pazvikamu zvakadaro uye, mushure mekugadzirisa zviito, shanda pamatanho anotevera epurojekiti.
Izvo zvinodikanwa kwete chete kutsiva node uye waya mumambure, asi zvakare kugadzirisa nemazvo zvese zvikamu zvekushanda kwakaringana kwemhinduro yakazara. Yakanga iri magadzirirwo akaedzwa nenzira iyi: kutanga basa kure nepakati, takaita setinozvipa isu "kodzero yekukanganisa" pasina kuisa panjodzi nzvimbo dzakakosha pakushanda kwebhizinesi.
Takacherechedza nzvimbo dzisingakanganisi nzira yekugadzira, pamwe chete nenzvimbo dzakaoma - maworkshops, kurodha uye kuburitsa chikwata, matura, nezvimwewo Munzvimbo dzakakosha, nguva inogamuchirwa yega yega network node zvakasiyana yakabvumirana nemutengi: kubva ku1 kusvika Maminitsi gumi nemashanu. Zvakanga zvisingagoneki kudzivirira zvachose kubvisa imwe network node, sezvo tambo ichifanirwa kuchinjika kubva kune yekare midziyo kuenda kune itsva, uye panguva yekuchinja kunodawo kusunungura "ndebvu" dzewaya dzakaumbwa mumakore akati wandei ekushanda pasina kukodzera. kutarisira (imwe yemhedzisiro yebasa rekunze rekuisa tambo dzetambo).
Basa racho rakakamurwa kuva nhanho dzinoverengeka.
Stage 1 β Audit. Kugadzirira uye kurongeka kwemaitiro ekuronga basa uye kuongororwa kwekugadzirira kwezvikwata: mutengi, mugadziri wekuisa, uye timu yedu.
Stage 2 -Kukudziridzwa kwefomati yekuita basa, nekuongorora kwakadzama uye kuronga. Isu takasarudza fomu yekutarisa ine chaiyo inotaridza kurongeka uye kutevedzana kwezviito, zvichidzika kusvika pakutevedzana kwekuchinja zvigamba tambo nechiteshi.
Stage 3 - Kuita basa mumakabati risingakanganisi kugadzirwa. Kufungidzira uye kugadzirisa nguva yekuderera kwezvikamu zvinotevera zvebasa.
Stage 4 -Kuita basa mumakabati anokanganisa kugadzirwa. Kufungidzira uye kugadziriswa kwekuderera kwechikamu chekupedzisira chebasa.
Stage 5 -Kuita basa mukamuri yeseva kushandura iyo yasara michina. Tangisa nzira pane iyo kernel itsva.
Stage 6 -Kutevedzana kuchinjika kweiyo system musimboti kubva kune ekare network masisitimu kune matsva ekuchinja kwakatsetseka kweiyo yese system yakaoma (VLAN, routing, nezvimwewo). Panguva ino, takabatanidza vashandisi vese uye takaendesa ese masevhisi kune nyowani Hardware, takaona kuti kubatana kwaive kwechokwadi, takava nechokwadi chekuti hapana kana masevhisi emabhizinesi akamiswa, ive nechokwadi chekuti kana paine matambudziko akaitika vaizobatanidzwa zvakananga kune kernel, izvo zvakaita kuti zvive nyore kugadzirisa matambudziko anogona kuitika uye kuseta kwekupedzisira.
Wire ndebvu bvudzi
Basa racho rakazova rakaoma zvakare nekuda kwemamiriro ezvinhu akaoma ekutanga.
Chekutanga, kune huwandu hukuru hwemanodhi uye zvikamu zvetiweki, ine yakaomesesa topology uye kupatsanurwa kwewaya zvinoenderana nechinangwa chavo. "Ndebvu" dzakadaro dzaifanira kubudiswa kunze kwemakabati uye nekushingaira "kukamirwa", kufunga kuti ndeipi yaibva kupi uye kwainotungamira.
Zvaitaridzika chimwe chinhu seichi:
saka:
kana:
Chechipiri, kune rimwe nerimwe basa rakadaro zvaive zvakakodzera kugadzirira faira inotsanangura maitiro. "Isu tinotora waya X kubva pachiteshi 1 chemidziyo yekare, toiisa muchiteshi chegumi nesere chemidziyo mitsva." Zvinonzwika zviri nyore, asi kana iwe uine makumi mana nemasere akavharika madoko mune yako sosi data, uye hapana yekudzika sarudzo (tinorangarira nezve 18x48x24), nzira chete yekubuda ndeye kushanda mumabhuraki. Iyo yakawanda waya iwe yaunokwanisa kudhonza kunze kwemidziyo yekare panguva imwe chete, iwe unokurumidza kuakama uye nekuaisa mune itsva network Hardware, kudzivirira kutadza uye downtime mumambure.
Naizvozvo, padanho rekugadzirira, takapatsanura network kuita zvidhinha - imwe neimwe yaive yeVLAN chaiyo. Chiteshi chega chega (kana chikamu chavo) pamidziyo yekare ndeimwe yeVLAN mune itsva network topology. Isu takazvibatanidza seizvi: madoko ekutanga ekuchinja aigara mushandisi network, yepakati - yekugadzira network, uye yekupedzisira - nzvimbo dzekuwana uye uplinks.
Iyi nzira yakaita kuti zvikwanise kudhonza kunze uye kusanganisa kubva mumidziyo yekare kwete waya imwe chete, asi 1-10, mune imwe chete. Izvi zvakakurumidzisa basa racho kakawanda.
Nenzira, izvi ndizvo zvinoita mawaya mumakabati mushure mekusangana:
kana, semuenzaniso, seizvi:
Mushure mekupedza danho rechipiri, takatora zororo kuti tiongorore zvikanganiso uye mapurojekiti emagetsi. Semuenzaniso, zvikanganiso zvidiki zvakangoerekana zvabuda nekuda kwekusarongeka mumadhayagiramu etiweki akapihwa kwatiri (chibatanidza chisina kunaka padhayagiramu zvinoreva zvisirizvo zvakatengwa chigamba tambo uye kudiwa kwekuchitsiva).
Iko kumbomira kwaidiwa, sezvo pakushanda kubva kudivi revhavha, kunyange diki glitch mukuita kwaisagamuchirwa. Kana chinangwa chaive chekuve nechokwadi chekudzikira pane network network isingapfuuri maminetsi mashanu, saka yaisagona kudarika. Chero kupi zvako kutsauka kubva purogiramu kwaifanira kubvumirana nemutengi.
Nekudaro, kufanoronga nekugovanisa purojekiti kuita mabhuroko kwakaita kuti zvikwanise kusangana nenguva yakarongwa munzvimbo dzese, uye kazhinji, dzivisa zvachose.
Dambudziko renguva - chirongwa chiri pasi peCOVID
Zvisinei, zvaisava pasina mamwe matambudziko. Ehe, iyo coronavirus yaive imwe yezvipingamupinyi.
Iro basa rakaomeswa nenyaya yekuti denda rakatanga, uye zvaisaita kuti nyanzvi dzese dzakabatanidzwa mukuita izvi dzivepo panguva yebasa panzvimbo yemutengi. Vashandi vesangano rekuisa chete ndivo vaibvumidzwa kupinda panzvimbo iyi, uye kutonga kwakaitwa kuburikidza nekamuri yeZoom - mairi maive neine network mainjiniya kubva kuLinxdatacenter, ini pachangu semaneja weprojekiti, injinjini yetiweki kubva kumutengi anotarisira basa, uye boka rinoita basa rekuisa.
Zvinetso zvisingaverengeki zvakamuka panguva yebasa, uye gadziridzo dzaifanira kuitwa pakubhururuka. Nenzira iyi, zvaive zvichibvira kukurumidza kudzivirira kukanganisa kwechivanhu (zvikanganiso munharaunda, zvikanganiso pakugadzirisa mamiriro ekugadzirisa basa, nezvimwewo).
Kunyange zvazvo chimiro chebasa chiri kure chaiita sechisina kujairika pakutanga kweprojekti, takakurumidza kujairana nemamiriro ezvinhu matsva ndokusvika padanho rekupedzisira rebasa.
Isu takatangisa gadziriso yenguva pfupi yetiweki zvigadziriso kuti tibvumire maviri network cores - yekare uye nyowani - kuti imhanye zvakafanana kuitira kuti uwane shanduko yakatsetseka. Zvisinei, zvakazoitika kuti imwe mutsara wakawedzerwa hauna kubviswa kubva pakugadzirisa faira yekernel itsva, uye shanduko haina kuitika. Izvi zvakatimanikidza kutora nguva tichitsvaga dambudziko.
Zvakazoitika kuti iyo huru traffic yakafambiswa nemazvo, uye iyo control traffic haina kusvika node kuburikidza neiyo nyowani musimboti. Kutenda kukupatsanurwa kwakajeka kweprojekiti mumatanho, zvaive zvichikwanisika kukurumidza kuona chikamu chetiweki apo dambudziko rakamuka, kuona dambudziko uye kurigadzirisa.
Uye somugumisiro
Mibairo yehunyanzvi yeprojekiti
Chekutanga pane zvese, musimboti mutsva weiyo nyowani bhizinesi network yakagadzirwa, iyo yatakavaka zvindori zvemuviri / zvine musoro. Izvi zvinoitwa nenzira yekuti shanduko yega yega mune network ine "ruoko rwechipiri". Munetiweki yekare, ma switch akawanda akabatanidzwa kune yakakosha munzira imwe chete, ruoko rumwe (uplink). Kana ikatyoka, switch yacho yakava isingasvikike zvachose. Uye kana akati wandei ma switch akabatana kuburikidza neuplink imwechete, saka tsaona yaizodzima dhipatimendi rese kana mutsara wekugadzira mubhizinesi.
Munetiweki nyowani, kunyangwe chiitiko chakakomba chetiweki hachizogone, pasi pemamiriro ezvinhu, kudzikisa network yese kana chikamu chakakosha chayo.
90% yemidziyo yese yetiweki yakagadziridzwa, midhiya inoshandura (signal propagation media converters) yakabviswa, uye kudiwa kwetambo dzakatsaurirwa magetsi emidziyo yemagetsi kwakabviswa nekubatanidza kuPoE switch, uko simba rinopihwa kuburikidza netambo dzeEthernet.
Zvakare, zvese zvinongedzo zvinongedzo mukamuri yeseva uye mumakabati emumunda zvakamisikidzwa - pane ese makiyi ekutaurirana node. Izvi zvakaita kuti zvikwanise kugadzirira dhayagiramu yepamusoro yemidziyo uye yekubatanidza mune network, ichiratidza mamiriro ayo chaiwo nhasi.
Dhizaini yedandemutande
Mhedzisiro inonyanya kukosha mumatekinoroji ehunyanzvi: basa rakakura-rakakura rezvivakwa rakaitwa nekukurumidza, pasina kugadzira chero kupindira kwebasa rebhizinesi uye rinenge risingaonekwe nevashandi varo.
Zvigumisiro zvebhizimisi zvepurojekiti
Mukuona kwangu, chirongwa ichi chinonakidza kunyanya kwete kubva kune unyanzvi, asi kubva kudivi resangano. Kuomerwa kwakange kuri mukuronga nekufunga kuburikidza nematanho ekuita mabasa epurojekiti.
Kubudirira kwepurojekiti kunotibvumira kutaura kuti danho redu rekuvandudza nzvimbo yetiweki mukati meLinxdatacenter service portfolio ndiyo sarudzo yakakodzera yekambani yekuvandudza vector. Nzira ine ushingi yekutonga kweprojekiti, zano rakakodzera, uye kuronga kwakajeka kwakatibvumira kupedzisa basa padanho rakakodzera.
Simbiso yemhando yebasa chikumbiro kubva kumutengi kuti aenderere mberi nekupa masevhisi ekuvandudza network panzvimbo dzayo dzasara muRussia.
