Mhoro, vaverengi veHabr! Muchinyorwa chekupedzisira, takataura nezve nzira iri nyore yekudzoreredza njodzi muAERODISK ENGINE kuchengetedza masisitimu - kudzokorora. Muchikamu chino, tichanyura mune imwe nyaya yakaoma uye inonakidza - iyo metrocluster, kureva, nzira yekudzivirira njodzi yega yega nzvimbo mbiri dze data, zvichibvumira nzvimbo dze data kuti dzishande mu-active-active mode. Tichakuudza, kukuratidza, kuputsa uye kugadzirisa.
Senguva dzose, dzidziso kutanga
A metrocluster isumbu rakapararira munzvimbo dzakati wandei mukati meguta kana dunhu. Izwi rekuti "cluster" rinonyatsoratidza kwatiri kuti iyo yakaoma ndeye otomatiki, ndiko kuti, kushandura cluster node kana kutadza kunoitika otomatiki.
Apa ndipo panowanikwa mutsauko mukuru pakati pemetrocluster uye kudzokorora nguva dzose. Automation yekushanda. Ndiko kuti, kana pane zvimwe zviitiko (data center kukundikana, yakaputsika nzira, nezvimwewo), iyo yekuchengetedza system ichaita yakazvimirira zviito zvinodiwa kuitira kuchengetedza kuwanikwa kwedata. Paunenge uchishandisa replicas yakajairwa, zviito izvi zvinoitwa zvachose kana zvishoma nemaoko nemutungamiriri.
Ko sei?
Chinangwa chikuru chinoteedzerwa nevatengi kana vachishandisa mamwe metrocluster kuita kudzikisa RTO (Recovery Time Objective). Ndiko kuti, kuderedza nguva yekudzoreredza yeIT masevhisi mushure mekutadza. Kana ukashandisa kudzokorora nguva dzose, nguva yekudzorera ichagara yakareba kudarika nguva yekudzorera ine metrocluster. Sei? Very simple. Mutariri anofanirwa kunge ari padhesiki rake uye achichinja kudzokorodza nemaoko, uye metrocluster inoita izvi otomatiki.
Kana iwe usina maneja akazvitsaurira pabasa asingarare, asingadyi, asingapute kana kurwara, uye achiona mamiriro ehurongwa hwekuchengetedza maawa makumi maviri nemana pazuva, saka hapana nzira yekuvimbisa kuti maneja achaita. kuvepo pakuchinja kwemaoko panguva yekutadza.
Saizvozvo, RTO mukushaikwa kwemetrocluster kana kusingafe admin ye99th level ye administrator duty sevhisi ichave yakaenzana nehuwandu hwenguva yekuchinja kwemasisitimu ese uye nguva yakawanda yenguva mushure mekuti maneja anovimbiswa kutanga kushanda. nemasisitimu ekuchengetedza uye masisitimu ane hukama.
Nokudaro, tinosvika pamhedziso iri pachena yokuti metrocluster inofanira kushandiswa kana chinodiwa cheRTO chiri maminetsi, kwete maawa kana mazuva.Ndiko kuti, kana pakaitika dambudziko rakaipisisa re data centre, dhipatimendi reIT rinofanira kupa bhizinesi nenguva. kudzorera kupinda kune IT -services mukati memaminitsi, kana kunyange masekondi.
Sei kushanda?
Padanho rezasi, metrocluster inoshandisa dhizaini yekudzokorodza data, yatakatsanangura muchinyorwa chakapfuura (ona. ) Sezvo kudzokorora kuchienderana, zvinodiwa pazviri zvinoenderana, kana kuti:
- optical fiber sefizikisi, 10 gigabit Ethernet (kana yakakwirira);
- kureba pakati pe data centers hakuna kupfuura 40 km;
- optical chiteshi kunonoka pakati pe data centers (pakati pekuchengetera masisitimu) inosvika 5 milliseconds (yakanyatso 2).
Zvose izvi zvinodiwa ndezvekupa mazano muzvisikwa, kureva kuti, metrocluster ichashanda kunyange kana izvi zvinodiwa zvikasasangana, asi tinofanira kunzwisisa kuti migumisiro yekusatevedzera zvinodiwa izvi yakaenzana nekuderera kwekushanda kwezvose zviri zviviri zvekuchengetedza. iyo metrocluster.
Saka, a synchronous replica inoshandiswa kuendesa data pakati pemasisitimu ekuchengetedza, uye replicas inochinja sei otomatiki uye, zvakanyanya kukosha, nzira yekudzivirira kupatsanura-uropi? Kuti uite izvi, pamwero wepamusoro, imwe nhengo yekuwedzera inoshandiswa - an arbiter.
Muyananisi anoshanda sei uye basa rake nderei?
Iyo arbiter kadiki kadiki muchina kana hardware cluster iyo inofanirwa kutangwa pane yechitatu saiti (semuenzaniso, muhofisi) uye inopa mukana kune yekuchengetedza sisitimu kuburikidza neICMP neSSH. Mushure mekutangwa, arbiter anofanira kuseta IP, uyezve kubva padivi rekuchengetera ratidza kero yayo, pamwe nemakero evanodzora vari kure vanotora chikamu mune metrocluster. Mushure meizvi, mutambi anogadzirira kushanda.
Iyo arbiter inogara ichitarisisa masisitimu ese ekuchengetera mumetrocluster uye kana imwe yekuchengetedza sisitimu isipo, mushure mekusimbisa kusavapo kubva kune imwe nhengo yeboka (imwe ye "kurarama" masisitimu ekuchengetedza), anosarudza kutanga maitiro ekuchinja kudzokorora mitemo. uye mapping.
Chinhu chakakosha zvikuru. Mutsinhanisi anofanira kugara ari panzvimbo yakasiyana neayo pane iyo yekuchengetedza masisitimu, kureva kuti, kwete munzvimbo yedata 1, iyo yekuchengetedza system 1 yakaiswa, kana munzvimbo yedata 2, iyo yekuchengetedza system 2 yakaiswa.
Sei? Nokuti iyi ndiyo chete nzira iyo mutongi, nerubatsiro rweimwe inosara yekuchengetedza masisitimu, inogona kusanzwisisika uye kunyatsoona kudonha kweimwe yemasaiti maviri uko masisitimu ekuchengetedza akaiswa. Chero dzimwe nzira dzekuisa arbiter dzinogona kukonzera kupatsanurwa-uropi.
Iye zvino ngatinyure mune zvakadzama zvebasa remutongi.
Iyo arbiter inomhanyisa masevhisi akati wandei anogara achivhota ese ekuchengetedza ma controller. Kana mhedzisiro yekuvhota ichisiyana neyekare (inowanikwa / isingawanikwe), zvino inonyorwa mudiki dhatabhesi, iyo inoshandawo pane arbiter.
Ngatitarisei pfungwa yebasa remutongi wedzimhosva zvakadzama.
Danho 1: Ziva kusavapo. Chiitiko chekutadza kwekuchengetedza system kusavapo kweping kubva kune ese ma controller eiyo imwechete yekuchengetedza system mukati me5 masekonzi.
Danho 2. Tanga nzira yekushandura. Mushure mokunge arbiter aona kuti imwe yezvigadziro zvekuchengetedza haisipo, anotumira chikumbiro kune "kurarama" hurongwa hwekuchengetedza kuitira kuti ave nechokwadi chokuti "yakafa" yekuchengetedza yakafa.
Mushure mekugamuchira murairo wakadaro kubva kune arbiter, yechipiri (live) yekuchengetedza system zvakare inotarisa kuwanikwa kweyakawa yekutanga yekuchengetedza system uye, kana isipo, inotumira simbiso kune arbiter yekufungidzira kwake. Iyo yekuchengetedza system haisi kuwanikwa.
Mushure mekugamuchira chisimbiso chakadaro, mutongi anotangisa nzira iri kure yekushandura kudzokorora uye kusimudza mepu pane izvo zvinyorwa zvaive zvichishanda (yekutanga) pane yakawa yekuchengetedza system, uye inotumira murairo kune yechipiri yekuchengetedza sisitimu kuti ichinje izvi replicas kubva yechipiri kuenda kupuraimari uye simudza mepu. Zvakanaka, yechipiri yekuchengetedza sisitimu, zvinoenderana, inoita maitiro aya, uyezve inopa mukana kune yakarasika maLUNs kubva pachayo.
Nei kumwe kuongorora kuchidiwa? Zve quorum. Ndiko kuti, ruzhinji rwehuwandu husinganzwisisike (3) nhamba yenhengo dzemasumbu dzinofanirwa kusimbisa kudonha kweimwe yemasumbu. Ndizvo chete ipapo sarudzo iyi ichave yechokwadi. Izvi zvinodikanwa kuitira kuti udzivise kukanganisa kushanduka uye, maererano, kupatsanurwa-uropi.
Nguva nhanho 2 inotora angangoita 5 - 10 masekondi, nekudaro, uchifunga nguva inodiwa kuona kusavapo (5 masekonzi), mukati me10 - 15 masekondi mushure metsaona, LUNs kubva kune yakawa yekuchengetedza system inozove inowanikwa yega kushanda nevapenyu. kuchengetedza system.
Zviri pachena kuti kuitira kuti udzivise kurasikirwa nekubatana nevatambi, iwe unofanirwawo kungwarira kugadzirisa nemazvo nguva yekubuda kune vanogamuchira. Nguva inokurudzirwa inokwana masekonzi makumi matatu. Izvi zvichadzivirira mubati kubva pakuparadzanisa kuwirirana kune hurongwa hwekuchengetedza panguva yekuchinja kwekutakura kana pakaitika njodzi uye inogona kuva nechokwadi chokuti hapana kukanganisa kweI / O.
Mirira kechipiri, zvinozoitika kuti kana zvese zvakanaka ne metrocluster, nei isu tichida kudzokorora zvachose?
Muchokwadi, zvese hazvisi nyore.
Ngatitarisei zvakanakira nekuipira metrocluster
Saka, takaona kuti zviri pachena zvakanakira metrocluster zvichienzaniswa neyakajairwa kudzokorora ndeidzi:
- Yakazara otomatiki, kuve nechokwadi kushoma kupora nguva pakaitika njodzi;
- Ndizvo zvose :-).
Uye zvino, tarisa, iyo cons:
- Solution mutengo. Kunyangwe iyo metrocluster muAerodisk masisitimu isingade yakawedzera rezenisi (iyo yakafanana rezenisi inoshandiswa seye replica), mutengo wemhinduro ucharamba wakatokwira kupfuura kushandisa synchronous replication. Iwe unozofanirwa kuita zvese zvinodiwa kune synchronous replica, pamwe nezvinodiwa zvemetrocluster zvine chekuita nekuwedzera switch uye imwe saiti (ona metrocluster kuronga);
- Kuoma kwemhinduro. Iyo metrocluster yakanyanya kuomarara kupfuura yenguva dzose replica, uye inoda kutarisisa kwakanyanya uye kushanda nesimba kuronga, kugadzirisa uye zvinyorwa.
Pakupedzisira. Metrocluster ndeyechokwadi tekinoroji yepamusoro uye yakanaka mhinduro kana iwe uchinyatsoda kupa RTO mumasekonzi kana maminetsi. Asi kana pasina basa rakadaro, uye RTO mumaawa yakanaka kune bhizinesi, saka hapana chikonzero chekupfura shiri duku kubva ku cannon. Iyo yakajairwa yevashandi-murombo kudzokorodza yakakwana, sezvo metro cluster ichizokonzera imwe mari uye kuomeswa kweiyo IT zvivakwa.
Kuronga kweMetrocluster
Ichi chikamu hachizviti igwara rakazara rekugadzira metrocluster, asi rinongoratidza nzira huru dzinofanirwa kuitwa kana ukafunga kuvaka system yakadai. Naizvozvo, kana uchinyatso shandisa metrocluster, ive shuwa yekubatanidza mugadziri wegadziriro yekuchengetedza (kureva isu) nemamwe masisitimu ane hukama ekubvunzana.
Nzvimbo
Sezvambotaurwa pamusoro, metrocluster inoda mashoma emasaiti matatu. Nzvimbo mbiri dzedhata apo masisitimu ekuchengetedza uye masisitimu ane hukama achashanda, pamwe nenzvimbo yechitatu iyo mutongi achashanda.
Iyo yakakurudzirwa kureba pakati penzvimbo dzedata haipfuuri makiromita makumi mana. Chinhambwe chakakura chinogona kukonzera kumwe kunonoka, izvo kana iri metrocluster zvisingadiwi zvakanyanya. Ngatikuyeuchidzei kuti kunonoka kunofanirwa kusvika ku40 milliseconds, kunyangwe zvichikurudzirwa kuti uzvichengete mukati me5.
Inokurudzirwa kutarisa kunonoka zvakare panguva yekuronga maitiro. Chero akawedzera kana mashoma akura anopa anopa optical fiber pakati pe data data anogona kuronga cheki chemhando nekukurumidza.
Kana zviri zvekunonoka pamberi pemutongi (kureva, pakati pesaiti yechitatu nembiri yekutanga), iyo yakakurudzirwa kunonoka chikumbaridzo inosvika mazana maviri milliseconds, ndiko kuti, yenguva dzose yekambani VPN yekubatanidza paInternet yakakodzera.
Kuchinja uye Networking
Kusiyana nechirongwa chekudzokorora, parinokwana kubatanidza masisitimu ekuchengetedza kubva kunzvimbo dzakasiyana, metrocluster chirongwa chinoda kubatanidza mauto neaviri masisitimu ekuchengetedza kunzvimbo dzakasiyana. Kuti zvive pachena kuti musiyano chii, zvirongwa zvose zviri kuratidzwa pasi apa.
Sezvinogona kuonekwa kubva pamufananidzo, nzvimbo yedu 1 mauto anotarisa zvose zvekuchengetedza hurongwa 1 uye hurongwa hwekuchengetedza 2. Uyezve, pane zvinopesana, saiti 2 mauto anotarisa zvose zvekuchengetedza system 2 uye hurongwa hwekuchengetedza 1. Ndiko kuti, yega yega muenzi anoona ese ekuchengetedza masisitimu. Ichi ndicho chinodiwa pakushanda kwemetrocluster.
Ehe, hapana chikonzero chekubatanidza mugadziri wega wega netambo yemaziso kune imwe nzvimbo yedata; hapana zviteshi kana tambo zvichakwana. Zvese izvi zvinongedzo zvinofanirwa kuitwa kuburikidza neEthernet 10G + kana FibreChannel 8G + switch (FC ndeye yekubatanidza mauto uye yekuchengetedza masisitimu eIO, chiteshi chekudzokorora chiri kuwanikwa chete neIP (Ethernet 10G +).
Iye zvino mazwi mashoma nezve network topology. Chinhu chakakosha ndechekugadziriswa kwema subnets. Izvo zvinodikanwa kuti utsanangure nekukurumidza akati wandei ma subnets emhando dzinotevera dzetraffic:
- Iyo yekudzokorora subnet pamusoro peiyo data ichave yakawiriraniswa pakati pekuchengetedza masisitimu. Panogona kunge paine akati wandei, mune iyi kesi hazvina basa, zvese zvinoenderana neyazvino (yakatoitwa) network topology. Kana paine maviri azvo, saka zviri pachena kuti nzira inofanirwa kugadziridzwa pakati pavo;
- Chengetedza subnets kuburikidza iyo mauto achawana ekuchengetedza zviwanikwa (kana iri iSCSI). Panofanira kunge paine imwe subnet yakadaro mune yega data data;
- Kudzora ma subnets, ndiko kuti, matatu routable subnets pane matatu masaiti kubva kune ekuchengetedza masisitimu anotariswa, uye arbiter iri zvakare ipapo.
Isu hatitarise ma subnets ekuwana zviwanikwa zvevaenzi pano, nekuti anovimba zvakanyanya nemabasa.
Kuparadzanisa traffic dzakasiyana muma subnets akasiyana kwakakosha zvakanyanya (zvakanyanya kukosha kuparadzanisa replica kubva kuI / O), nekuti kana iwe ukasanganisa traffic yese mune imwe "gobvu" subnet, saka traffic iyi haigone kubata, uye mukati. mamiriro enzvimbo mbiri dze data izvi zvinogona kukonzera akasiyana network kudhumhana sarudzo. Hatisi kuzoongorora zvakadzama munyaya iyi mukati megadziriro yechinyorwa chino, sezvo iwe unogona kuverenga nezve kuronga network yakatambanudzwa pakati pe data data pane zviwanikwa zvevagadziri vemidziyo yetiweki, uko izvi zvinotsanangurwa zvakadzama.
Arbiter configuration
Iyo arbiter inofanirwa kupa mukana kune ese manejimendi ekuchengetedza ekuchengetedza system kuburikidza neICMP uye SSH protocol. Iwe unofanirwawo kufunga nezve failsafe ye arbiter. Pane nuance pano.
Arbiter failover inodiwa zvakanyanya, asi haidiwi. Chii chinoitika kana mutambi akadonha panguva isiri iyo?
- Kushanda kwe metrocluster mune yakajairika modhi hakushanduke, nekuti arbtir haina zvachose mhedzisiro pakushanda kwemetrocluster mune yakajairika mode (basa rayo ndere kushandura mutoro pakati penzvimbo dzedata panguva yakakodzera)
- Uyezve, kana arbiter nokuda kwechikonzero chimwe kana chimwe akawira uye "akarara kuburikidza" nenjodzi munzvimbo yedata, saka hapana kuchinja kuchaitika, nokuti hapazovi nemunhu anopa mirairo yekuchinja inodiwa uye kuronga quorum. Muchiitiko ichi, metrocluster inoshanduka kuita chirongwa chenguva dzose nekudzokorora, icho chinozofanirwa kuchinjirwa nemaoko panguva yenjodzi, iyo inokanganisa RTO.
Chii chinotevera kubva pane izvi? Kana iwe uchinyatsoda kuve nechokwadi cheRTO shoma, unofanirwa kuve nechokwadi chekuti arbiter inoshivirira kukanganisa. Pane nzira mbiri dzeizvi:
- Tanga muchina chaiwo une arbiter pane hypervisor inoshivirira, rombo rakanaka vese vakuru hypervisors vanotsigira kukanganisa kushivirira;
- Kana panzvimbo yechitatu (muhofisi yakajairika) iwe wakanyanya simbe yekuisa yakajairika cluster uye pasina iripo hypervozor cluster, saka isu takapa Hardware vhezheni yearbiter, inogadzirwa mubhokisi re2U umo maviri akajairwa. x-86 maseva anoshanda uye anogona kurarama kutadza kwenzvimbo.
Isu tinokurudzira zvakasimba kuve nechokwadi chekutadza kushivirira kweiyo arbiter, zvisinei nekuti metrocluster haidi iyo mune yakajairika mode. Asi sezvinoratidzwa nedzidziso uye maitiro, kana iwe ukavaka chivakwa chechokwadi chenjodzi, saka zviri nani kuitamba zvakachengeteka. Zviri nani kuti uzvidzivirire iwe nebhizinesi rako kubva ku "mutemo wekuipa," ndiko kuti, kubva mukukundikana kwevose vari vaviri mutongi uye imwe yenzvimbo iyo yekuchengetedza system iripo.
Solution architecture
Tichifunga zvinodiwa pamusoro, tinowana inotevera general solution yekuvaka.
MaLUN anofanirwa kugovaniswa zvakaenzana munzvimbo mbiri kudzivirira kuwandisa. Panguva imwecheteyo, kana uchiyera munzvimbo mbiri dze data, haufanirwe kungosanganisira vhoriyamu yakapetwa kaviri (inodiwa kuchengetedza data panguva imwe chete pamasisitimu maviri ekuchengetedza), asiwo kuita kaviri muIOPS neMB/s kuitira kudzivirira kushatiswa kwechishandiso mu. chiitiko chekukundikana kweimwe yenzvimbo dzedata. ov.
Takaparadzana, tinocherekedza kuti nemaitiro akakodzera ekuyera (kureva, chero isu takapa iwo epamusoro miganhu yeIOPS neMB/s, pamwe neinodiwa CPU uye RAM zviwanikwa), kana imwe yemasisitimu ekuchengetedza mu metro cluster inotadza, hapazove nekudonha kwakanyanya mukuita pasi pemamiriro ekushanda kwenguva pfupi pane imwe yekuchengetedza system.
Izvi zvinotsanangurwa nenyaya yekuti kana masayiti maviri ari kushanda panguva imwe chete, kudzokorora kwakafanana "kunodya" hafu yebasa rekunyora, sezvo kutengeserana kwega kwega kunofanirwa kunyorwa kune maviri ekuchengetedza masisitimu (akafanana neRAID-1/10). Saka, kana imwe yemasisitimu ekuchengetedza ikatadza, pesvedzero yekudzokorora kwechinguva (kusvikira iyo yakundikana yekuchengetedza system yapora) inonyangarika, uye isu tinowana kuwedzera kaviri mukunyora kuita. Mushure mekunge maLUNs eiyo yakundikana kuchengetedza system atangazve pane yekushanda yekuchengetedza sisitimu, kuwedzera uku kwakapetwa kaviri kunonyangarika nekuda kwekuti mutoro unoonekwa kubva kuLUNs yeimwe gadziriro yekuchengetedza, uye isu tinodzokera kune imwecheteyo nhanho yekushanda yataive nayo pamberi "kuwa", asi mukati megadziriro yeimwe saiti.
Nerubatsiro rwekugona saizi, unogona kuve nechokwadi mamiriro ayo vashandisi vasingazonzwa kutadza kwese kuchengetedza system zvachose. Asi isu tinodzokorora zvakare, izvi zvinoda kunyatsochenjerera saizi, iyo, nenzira, iwe unogona kutibata mahara :-).
Kugadzira metrocluster
Kumisikidza metrocluster kwakafanana nekumisikidza kudzokorora, kwatakatsanangura mairi . Naizvozvo, ngatitarisei pane kusiyana chete.
