Mhoro, vaverengi veHabr. Nechinyorwa ichi tinovhura nhevedzano ichataura nezve hyperconverged system AERODISK vAIR yatakagadzira. Pakutanga, taida kutaurira zvinhu zvose munyaya yekutanga, asi hurongwa hwakaoma, saka tichadya nzou muzvikamu.
Ngatitange nyaya yacho nenhoroondo yekusikwa kwegadziriro, tsvaga muARDFS faira system, iyo ndiyo nheyo ye vAIR, uye zvakare taura zvishoma pamusoro pekuiswa kweiyi mhinduro pamusika weRussia.
Muzvinyorwa zvinotevera tichataura zvakadzama pamusoro pezvakasiyana zvekuvaka zvikamu (cluster, hypervisor, load balancer, monitoring system, etc.), maitiro ekumisikidza, kusimudza nyaya dzerezinesi, kuratidza zvakasiyana bvunzo dzekupunzika uye, chokwadi, nyora nezve kuyedzwa kwemutoro uye saizi. Isu tichapa zvakare chinyorwa chakasiyana kune nharaunda vhezheni yevAIR.
Is Aerodisk inyaya pamusoro pekuchengetedza masisitimu? Kana kuti nei takatanga kuita hyperconvergence pakutanga?
Pakutanga, pfungwa yekugadzira yedu hyperconvergence yakauya kwatiri kune imwe nzvimbo yakapoteredza 2010. Panguva iyoyo, pakanga pasina Aerodisk kana mhinduro dzakafanana (yekutengesa mabhokisi hyperconverged masisitimu) pamusika. Basa redu raive rinotevera: kubva kune seti yemaseva ane madhisiki emunharaunda, akabatanidzwa neanobatana kuburikidza neEthernet protocol, zvaive zvakafanira kugadzira yakawedzera kuchengetedza uye kuvhura chaiwo michina uye software network ipapo. Zvese izvi zvaifanira kuitwa pasina masisitimu ekuchengetedza (nekuti pakanga pasina mari yekuchengetera masisitimu nemidziyo yayo, uye isu takanga tisati tagadzira yedu yekuchengetera masisitimu).
Takaedza akawanda akavhurika sosi mhinduro uye pakupedzisira takagadzirisa dambudziko iri, asi mhinduro yaive yakaoma uye yakaoma kudzokorora. Kunze kwezvo, mhinduro iyi yaive muchikamu che "Inoshanda here? Usabate! Naizvozvo, tapedza dambudziko iri, hatina kuzosimudzira pfungwa yekushandura mhedzisiro yebasa redu kuita chigadzirwa chakazara.
Mushure mechiitiko ichocho, takasuduruka kubva pane iyi pfungwa, asi isu tichiri kunzwa kuti dambudziko iri rakanyatsogadziriswa, uye mabhenefiti emhinduro yakadaro aive akanyanya kujeka. Zvadaro, zvigadzirwa zveHCI zvakaburitswa zvemakambani ekunze zvakangosimbisa manzwiro aya.
Naizvozvo, pakati pegore ra2016, takadzokera kubasa iri sechikamu chekugadzira chigadzirwa chakazara. Panguva iyoyo takanga tisati tave nehukama nemainvestimer, saka taifanira kutenga stand yekusimudzira mari yedu kwete yakakura kwazvo. Takaunganidza maseva akashandiswa uye switch paAvito, takadzika kubhizinesi.
Basa guru rekutanga raive rekugadzira yedu, kunyangwe iri nyore, asi yedu pachedu faira system, iyo yaigona otomatiki uye yakaenzana kugovera data muchimiro chezvidhinha panhamba yenhamba yemasumbu, ayo akabatanidzwa nekubatanidza kuburikidza neEthernet. Panguva imwecheteyo, FS inofanira kukwira zvakanaka uye nyore uye yakazvimiririra kune masisitimu ari pedyo, i.e. kuparadzaniswa kubva kuVAIR muchimiro che "chete nzvimbo yekuchengetedza".
Kutanga vAIR pfungwa
Isu takasiya nemaune kushandiswa kweyakagadzirirwa-yakavhurwa sosi mhinduro yekuronga yakatambanudzwa chengetedzo (ceph, gluster, luster nezvimwe zvakadaro) tichifarira budiriro yedu pachedu, sezvo isu taitova neruzivo rwakawanda rweprojekiti navo. Ehe, mhinduro idzi pachadzo dzakanakisa, uye tisati tashanda paAerodisk, takaita zvinopfuura chirongwa chimwe chekubatanidza navo. Asi chinhu chimwe chete kuita basa rakananga kune mumwe mutengi, vashandi vezvitima uye, pamwe, kutenga rutsigiro rwemutengesi mukuru, uye chimwewo chinhu kugadzira chigadzirwa chiri nyore kudzokororwa chinozoshandiswa kune akasiyana mabasa, ayo isu, se mutengesi, angatoziva nezvedu isu hatizo. Nechinangwa chechipiri, zviripo zvakavhurika sosi zvigadzirwa zvaive zvisina kutikodzera, saka takasarudza kugadzira yakagoverwa faira system isu pachedu.
Makore maviri gare gare, vagadziri vakati wandei (avo vakabatanidza basa pavAIR nebasa pane yekare Injini yekuchengetedza system) vakawana imwe mhedzisiro.
Pakazosvika 2018, takanga tanyora iri nyore faira system uye tikaiwedzera neiyo inodiwa hardware. Iyo sisitimu yakabatanidza emuviri (yemunharaunda) dhisiki kubva kune akasiyana maseva kuita dziva rimwe rakafuratira kuburikidza neyemukati yekubatanidza uye "kucheka" iwo kuita chaiwo mabhuraki, wobva wavhara zvishandiso zvine madhigirii akasiyana ekushivirira kukanganisa akagadzirwa kubva kune chaiwo mabhuroki, paari iwo chaiwo akagadzirwa. uye kuurayiwa uchishandisa KVM hypervisor mota.
Hatina kunetseka zvakanyanya nezita reiyo faira system uye tikanyatsoidaidza kuti ARDFS (fembera kuti inomirirei))
Iyi prototype yaitaridzika zvakanaka (kwete yekuona, hongu, pakanga pasina dhizaini yekuona) uye yakaratidza mhedzisiro yakanaka maererano nekuita uye kuyera. Mushure memhedzisiro yekutanga chaiyo, isu takaisa chirongwa ichi mukufamba, tichironga yakazara-yakazara budiriro nharaunda uye yakaparadzana timu yaibata chete neVAIR.
Panguva iyoyo chete, dhizaini yegadziriso yakange yakura, iyo isati yave nekuchinja kukuru.
Kunyura muARDFS faira system
ARDFS ndiyo nheyo yeVAIR, iyo inopa kugoverwa, kukanganisa-kushivirira data kuchengetedza mukati meboka rose. Imwe ye (asi kwete iyo chete) yakasarudzika maficha eARDFS ndeyekuti haishandise chero akawedzera akazvitsaurira maseva emetadata uye manejimendi. Izvi zvakagadzirirwa kurerutsa kugadzirisa kwemhinduro uye nekuvimbika kwayo.
Kuchengetedza chimiro
Mukati mese node dzeboka, ARDFS inoronga dziva rine musoro kubva kune yese iripo disk space. Zvakakosha kunzwisisa kuti dziva harisati rave data kana nzvimbo yakarongwa, asi kungoita markup, i.e. Chero ma node ane vAIR akaiswa, kana awedzerwa kuboka, anongowedzerwa kune yakagovaniswa ARDFS dziva uye disk zviwanikwa zvinongove zvakagovaniswa musumbu rese (uye inowanikwa kune ramangwana data rekuchengetedza). Iyi nzira inokubvumira kuti uwedzere uye ubvise node panhunzi pasina kukanganisa kwakakomba pane yagara ichimhanya system. Avo. Iyo sisitimu iri nyore kwazvo kuyera "muzvidhinha", kuwedzera kana kubvisa node musumbu kana zvichidikanwa.
Virtual disks (zvinhu zvekuchengetedza zvemakina chaiwo) zvinowedzerwa pamusoro pedziva reARDFS, iro rakavakwa kubva kumabhuroko chaiwo e4 megabytes muhukuru. Madhisiki chaiwo anochengeta data. Iyo yekutadza kushivirira chirongwa inoiswawo paiyo virtual disk level.
Sezvaungave watofungidzira, nekuda kwekutadza kushivirira kweiyo disk subsystem, isu hatishandise pfungwa yeRAID (Redundant array yemadhisiki akazvimirira), asi shandisa RAIN (Redundant array yemaNode akazvimirira). Avo. Kukanganisa kushivirira kunoyerwa, otomatiki, uye inotungamirwa zvichibva pane node, kwete madhisiki. Madhisiki, hongu, zvakare chinhu chekuchengetedza, iwo, sezvimwe zvese, anotariswa, unogona kuita ese akajairwa mashandiro navo, kusanganisira kuunganidza yemunharaunda hardware RAID, asi sumbu rinoshanda zvakananga pane node.
Mumamiriro ezvinhu apo iwe unoda chaizvo RAID (semuenzaniso, chiitiko chinotsigira kutadza kwakawanda pamasumbu madiki), hapana chinokutadzisa kushandisa emunharaunda RAID controllers, uye kuvaka yakatambanudzwa kuchengetedza uye RAIN architecture pamusoro. Mamiriro ezvinhu aya ane hupenyu uye anotsigirwa nesu, saka tichataura nezvayo mune chinyorwa nezve yakajairika mamiriro ekushandisa vAIR.
Kuchengetera Mhosva Kushivirira Schemes
Panogona kuve nekutadza kushivirira zvirongwa zvemadhisiki chaiwo muVAIR:
1) Kudzokorora chinhu kana kungodzokorora - iyi nzira yekushivirira kukanganisa iri nyore setsvimbo netambo. Synchronous replication inoitwa pakati pemanodhi nechinhu che2 (2 makopi pasumbu) kana 3 (3 makopi, zvichiteerana). RF-2 inobvumira dhisiki chaiyo kumira kutadza kweimwe node musumbu, asi "inodya" hafu yevhoriyamu inobatsira, uye RF-3 inomira nekutadza kwemanodhi maviri musumbu, asi inochengeta 2/2 ye vhoriyamu inobatsira kune zvayaida. Ichi chirongwa chakafanana chaizvo neRAID-3, ndiko kuti, dhisiki chaiyo yakagadziriswa muRF-1 inopesana nekutadza kwechero node musumbu. Muchiitiko ichi, zvinhu zvose zvichave zvakanaka nedheta uye kunyange I / O haizomira. Kana iyo node yakadonha ichidzokera kubasa, otomatiki data kudzoreredza / kuwiriranisa kuchatanga.
Pazasi pane mienzaniso yekugoverwa kweRF-2 uye RF-3 data mune yakajairika mode uye mune yekutadza mamiriro.
Tine muchina unokwana 8MB yedata rakasiyana (rinobatsira), rinomhanya pa4 vAIR node. Zviri pachena kuti muchokwadi hazvigoneki kuti pachava nehuwandu hwakadaro, asi nokuda kwechirongwa chinoratidza pfungwa yekushanda kweARDFS, muenzaniso uyu unonzwisisika. AB ndeye 4MB chaiyo mabhuraki ane yakasarudzika chaiyo muchina data. RF-2 inogadzira makopi maviri ezvivharo izvi A1 + A2 uye B1 + B2, zvichiteerana. Aya mabhuroki "akaiswa" munzvimbo dzese, kudzivirira kupindirana kweiyo data pane imwechete node, kureva, kopi A1 haizowanikwa pane imwechete node sekopi A2. Zvimwe chete neB1 uye B2.
Kana imwe yemanode ikakundikana (somuenzaniso, node No. 3, iyo ine kopi yeB1), iyi kopi inongogadziriswa pane node apo pasina kopi yekopi yayo (kureva, kopi yeB2).
Nekudaro, iyo chaiyo dhisiki (uye iyo VM, zvinoenderana) inogona kurarama zviri nyore kutadza kweimwe node muRF-2 chirongwa.
Iyo replication scheme, nepo iri nyore uye yakavimbika, inotambura nedambudziko rakafanana neRAID1 - isina kukwana nzvimbo inoshandiswa.
2) Erasure coding kana erasure coding (inozivikanwawo se "redundant coding", "erasure coding" kana "redundancy code") iripo kugadzirisa dambudziko riri pamusoro. EC chirongwa chekudzokorodza chinopa kuwanikwa kwe data yakakwira neakadzika dhisiki nzvimbo pamusoro kana ichienzaniswa nekudzokorora. Nheyo yekushandisa yemuchina uyu yakafanana neRAID 5, 6, 6P.
Pakukodha, maitiro eEC anokamura chivharo chaicho (4MB nekukasira) kuita madiki "data chunks" zvichienderana neEC scheme (semuenzaniso, chirongwa che 2+1 chinokamura 4MB yega yega kuita 2 2MB chunks). Tevere, maitiro aya anoburitsa "parity chunks" ye "data chunks" iyo isina kukura pane imwe yezvikamu zvakakamurwa kare. Pakudhirodha, EC inogadzira machunks akashaikwa nekuverenga iyo "inopona" data pane yese cluster.
Semuenzaniso, virtual disk ine 2 + 1 EC chirongwa, inoshandiswa pa 4 cluster nodes, inotsungirira nyore nyore kukanganisa kweimwe node musumbu nenzira yakafanana neRF-2. Muchiitiko ichi, mari yepamusoro ichave yakaderera, kunyanya, iyo inobatsira yehuwandu hweRF-2 ndeye 2, uye yeEC 2 + 1 ichava 1,5.
Kuti uitsanangure zviri nyore, iyo yakakosha ndeyekuti iyo chaiyo block yakakamurwa kuita 2-8 (nei kubva pa2 kusvika ku8, ona pazasi) "zvidimbu", uye kune izvi zvidimbu "zvidimbu" zvekuenzana kwevhoriyamu yakafanana zvinoverengerwa.
Nekuda kweizvozvo, data uye parity zvakagoverwa zvakaenzana munzvimbo dzese dzesumbu. Panguva imwecheteyo, sekudzokorora, ARDFS inogovera data pakati pemanodhi nenzira yekudzivirira data yakafanana (makopi edheta uye kuenzana kwavo) kubva pakuchengetwa pane imwe node, kuitira kubvisa mukana wekurasikirwa nedhata. kune chokwadi chekuti data uye kuenzana kwavo zvichangoerekana zvaguma pane imwe yekuchengetedza node inotadza.
Pazasi pane muenzaniso, ine yakafanana 8 MB chaiyo muchina uye 4 node, asi ine EC 2 + 1 chirongwa.
Mabhuroki A neB akakamurwa kuita zvidimbu zviviri zve2 MB chimwe nechimwe (mbiri nekuti 2+1), kureva, A1+A2 uye B1+B2. Kusiyana nereplica, A1 haisi kopi yeA2, ivhavha A, yakakamurwa kuita zvikamu zviviri, zvakafanana nebhokisi B. Pakazara, tinowana maviri maviri e4MB, imwe neimwe ine maviri-MB zvidimbu. Tevere, kune imwe neimwe yemaseti aya, kuenzana kunoverengerwa nehuwandu husingapfuure chidimbu chimwe (kureva 2 MB), tinowana yekuwedzera + 2 zvidimbu zveparity (AP uye BP). Pakazara isu tine 4 Γ 2 data + 2 Γ 2 parity.
Zvadaro, zvidimbu "zvakaiswa" pakati pemanodhi kuitira kuti data irege kupindirana nekuenzanisa kwavo. Avo. A1 uye A2 haizove pane imwechete node seAP.
Muchiitiko chekukundikana kweimwe node (somuenzaniso, zvakare yechitatu), iyo yakawa block B1 ichadzoserwa otomatiki kubva kuBP parity, iyo inochengetwa pane node No. kwete B-parity, i.e. chikamu cheBP. Mumuenzaniso uyu, iyi node Nha
Ndine chokwadi chekuti muverengi ane mubvunzo:
"Zvese zvawatsanangura zvakagara zvichiitwa nevakwikwidzi uye mune yakavhurika sosi mhinduro, ndeupi musiyano uripo pakati pekushandisa kwako EC muARDFS?"
Uye ipapo pachava neanonakidza maficha eARDFS.
Erasure coding nekutarisa kuchinjika
Pakutanga, takapa EC X+Y chirongwa chinogoneka, apo X yakaenzana nenhamba kubva pa2 kusvika pa8, uye Y yakaenzana nenhamba kubva pa1 kusvika pa8, asi nguva dzose iri pasi kana kuenzana naX. Ichi chirongwa chinopiwa kuitira kusununguka. Kuwedzera nhamba yezvidimbu zve data (X) iyo iyo chaiyo block yakakamurwa inobvumira kudzikisa mutengo wepamusoro, ndiko kuti, kuwedzera nzvimbo inoshandiswa.
Kuwedzera huwandu hweparity chunks (Y) kunowedzera kuvimbika kweiyo virtual disk. Iyo yakakura iyo Y kukosha, iyo yakawanda nodes musumbu inogona kutadza. Ehezve, kuwedzera huwandu hwehuwandu kunoderedza huwandu hwehunogona kushandiswa, asi uyu mutengo wekubhadhara kuvimbika.
Kutsamira kwekuita pamaseketi eEC kunenge kwakananga: iyo yakawanda "zvidimbu", iyo yakaderera kuita; pano, hongu, maonero akaenzana anodiwa.
Iyi nzira inobvumira vatariri kugadzirisa yakatambanudzwa kuchengetedza nekunyanya kushanduka. Mukati meDFS dziva, unogona kushandisa chero kukanganisa kushivirira zvirongwa uye kusanganiswa kwavo, izvo, mumaonero edu, zvinobatsirawo zvakanyanya.
Pazasi pane tafura inoenzanisa akati wandei (kwete zvese zvinogoneka) RF uye EC zvirongwa.
Tafura inoratidza kuti kunyange iyo yakanyanya "terry" musanganiswa EC 8 + 7, iyo inobvumira kurasikirwa kusvika ku7 nodes muboka panguva imwe chete, "inodya" nzvimbo isingashandisike (1,875 maringe ne2) pane kudzokorora kwakajairwa, uye inodzivirira kanomwe zviri nani. , iyo inoita kuti iyi nzira yekudzivirira, kunyange yakanyanya kuoma, inonyanya kutaridzika mumamiriro ezvinhu apo inofanirwa kuve nechokwadi chekuvimbika kwakanyanya mumamiriro ediki disk space. Panguva imwecheteyo, iwe unofanirwa kunzwisisa kuti imwe neimwe "plus" ku X kana Y ichave yekuwedzera mashandiro epamusoro, saka mumatatu pakati pekuvimbika, kuchengetedza uye kuita iwe unofanirwa kusarudza zvakanyatsonaka. Nechikonzero ichi, isu tichapa yakaparadzana chinyorwa kudzima coding saizi.
Kuvimbika uye kuzvimiririra kwefaira system
ARDFS inomhanya munharaunda munzvimbo dzese dzesumbu uye inoawiriranisa ichishandisa yayo nzira kuburikidza yakatsaurirwa Ethernet interfaces. Chinhu chakakosha ndechekuti ARDFS yakazvimirira inosanganisa kwete chete data, asiwo metadata ine chekuita nekuchengetedza. Tichiri kushanda paARDFS, takadzidza panguva imwe chete mhinduro dzinoverengeka dziripo uye takaona kuti mazhinji anowiriranisa faira system meta vachishandisa yekunze yakagoverwa DBMS, yatinoshandisawo kuwiriranisa, asi magadzirirwo chete, kwete FS metadata (nezveizvi uye mamwe ma subsystems ane hukama. muchinyorwa chinotevera).
Kuwiriranisa FS metadata uchishandisa yekunze DBMS, hongu, mhinduro inoshanda, asi ipapo kuenderana kweiyo data yakachengetwa paARDFS inoenderana nekunze kweDBMS uye maitiro ayo (uye, kutaura pachena, imukadzi asingafadzi), iyo mukati maonero edu akaipa. Sei? Kana iyo metadata yeFS ikakuvadzwa, iyo data yeFS pachayo inogona zvakare kunzi "zvakanakai," saka takasarudza kutora nzira yakaoma asi yakavimbika.
Isu takagadzira iyo metadata yekuwiriranisa subsystem yeARDFS isu pachedu, uye inogara yakazvimiririra yakazvimirira kubva padyo masisitimu. Avo. hapana imwe subsystem inogona kukanganisa ARDFS data. Mukuona kwedu, iyi ndiyo nzira yakavimbika uye yakarurama, asi nguva ichataura kana izvi zviri izvo chaizvo. Mukuwedzera, kune imwezve bhenefiti neiyi nzira. ARDFS inogona kushandiswa yakazvimiririra yevAIR, sekunge yakatambanudzwa kuchengetedza, yatichashandisa zvechokwadi mune ramangwana zvigadzirwa.
Nekuda kweizvozvo, nekugadzira ARDFS, takagamuchira inochinjika uye yakavimbika faira sisitimu inopa sarudzo kwaunogona kuchengetedza pahuwandu kana kupa zvese pamusoro pekuita, kana kugadzira yekupedzisira-yakavimbika kuchengetedza nemutengo unonzwisisika, asi uchideredza kuita zvinodiwa.
Pamwe chete nemutemo wakareruka werezinesi uye inochinjika yekuendesa modhi (yakatarisa kumberi, vAIR inopihwa rezinesi nenode, uye inounzwa sesoftware kana sesoftware package), izvi zvinokutendera kuti unyatso kugadzirisa mhinduro kune zvakasiyana siyana zvinodiwa nevatengi uye zvino chengetedza zviri nyore izvi.
Ndiani anoda chishamiso ichi?
Kune rumwe rutivi, tinogona kutaura kuti kune vatove nevatambi pamusika vane zvakakomba mhinduro mumunda we hyperconvergence, uye apa ndipo patiri kuenda chaizvo. Zvinoita sekuti chirevo ichi ichokwadi, ASI ...
Kune rumwe rutivi, patinoenda kuminda uye tichikurukura nevatengi, isu nevatinoshanda navo tinoona kuti izvi hazvisizvo. Kune akawanda mabasa e hyperconvergence, mune dzimwe nzvimbo vanhu vaisatomboziva kuti mhinduro dzakadaro dziripo, mune dzimwe dzaiita sedzinodhura, mune dzimwe pakanga pasina bvunzo dzeimwe mhinduro, uye mune dzimwe dzinorambidza kutenga zvachose nekuda kwezvirango. Kazhinji, munda wakave usina kurima, saka takaenda kunosimudza mhandara ivhu))).
Irini yekuchengetedza system iri nani pane GCS?
Sezvo isu tichishanda nemusika, isu tinowanzo kubvunzwa kana zviri nani kushandisa chirongwa chekare chine masisitimu ekuchengetedza, uye nguva yekushandisa hyperconvergent? Makambani mazhinji anogadzira GCS (kunyanya ayo asina masisitimu ekuchengetedza mumapotfolio avo) anoti: "Sitimu dzekuchengetera dzave kusashanda, hyperconverged chete!" Ichi chirevo chakashinga, asi hachiratidzi zvachose chokwadi.
Muchokwadi, musika wekuchengetera uri kuenda kune hyperconvergence uye mhinduro dzakafanana, asi pane nguva dzose "asi".
Chekutanga, nzvimbo dzedata uye zvivakwa zveIT zvakavakwa zvinoenderana neklassic scheme ine masisitimu ekuchengetedza hazvigone kuvakwa zvakare nyore, saka iyo yemazuva ano uye kupedzwa kwezvivakwa zvakadaro ichiri nhaka ye5-7 makore.
Chechipiri, zvivakwa zviri kuvakwa iye zvino zvakanyanya (zvinoreva kuti Russian Federation) inovakwa maererano neklassical chirongwa vachishandisa kuchengetedza masisitimu, uye kwete nekuti vanhu havazive nezve hyperconvergence, asi nekuti iyo hyperconvergence musika mutsva, mhinduro uye. zviyero hazvisati zvasimbiswa , IT vanhu havasati vakadzidziswa, vane ruzivo rushoma, asi vanoda kuvaka data data pano uye ikozvino. Uye maitiro aya achagara kwemamwe makore 3-5 (uyezve imwe nhaka, ona pfungwa 1).
Chetatu, pane kuganhurirwa kwehunyanzvi mukuwedzera kudiki kunonoka kwe2 milliseconds pakunyora (kusingasanganisire cache yemuno, hongu), inova iyo mutengo wekugovera kuchengetedza.
Zvakanaka, ngatisakanganwe nezve kushandiswa kwemasevha makuru emuviri anoda vertical scaling ye disk subsystem.
Kune akawanda anodiwa uye anozivikanwa mabasa uko kuchengetedza masisitimu anoita zvirinani pane GCS. Pano, hongu, avo vanogadzira vasina masisitimu ekuchengetedza mune yavo chigadzirwa portfolio havabvumirani nesu, asi isu takagadzirira kukakavara zvine musoro. Ehe, isu, sevagadziri vezvigadzirwa zvese zviri zviviri, tichanyatso enzanisa masisitimu ekuchengetedza uye GCS mune imwe yeramangwana zvinyorwa zvedu, apo isu ticharatidza zvakajeka izvo zviri nani pasi pemamiriro api.
Uye kupi hyperconverged mhinduro dzinoshanda zvirinani pane kuchengetedza masisitimu?
Kubva pamapfundo ari pamusoro, mhedziso nhatu dziri pachena dzinogona kuitwa:
- Iko kune mamwe 2 milliseconds e latency yekurekodha, iyo inowanzoitika mune chero chigadzirwa (ikozvino isu hatisi kutaura nezve synthetics, nanoseconds inogona kuratidzwa pane synthetics), haina kutsoropodza, hyperconvergent yakakodzera.
- Iko kuremerwa kubva kumasevha makuru emuviri anogona kushandurwa kuita akawanda madiki madiki uye akagovaniswa pakati pemanodhi, hyperconvergence ichashanda zvakanaka ipapo.
- Iko kuyera kuyera kunonyanya kukosha kupfuura kuyera kwakatwasuka, GKS ichashanda zvakanaka ipapo.
Ndedzipi idzi mhinduro?
- Yese yakajairwa masevhisi masevhisi (dhairekitori sevhisi, tsamba, EDMS, faira maseva, madiki kana epakati ERP uye BI masisitimu, nezvimwewo). Isu tinodaidza izvi "general computing."
- Zvivakwa zvevanopa makore, pazvinofanirwa kukurumidza uye kuenzanisa yakatwasuka uye zviri nyore "kucheka" nhamba huru yemashini chaiwo evatengi.
- Virtual desktop infrastructure (VDI), uko michina midiki midiki yemushandisi inomhanya uye chinyararire "inoyangarara" mukati mechikwata cheunifomu.
- Bazi network, uko bazi rega rega rinoda mwero, kutadza-kushivirira, asi kusingadhure zvivakwa zve15-20 chaiwo michina.
- Chero yakagoverwa komputa (mahombe data masevhisi, semuenzaniso). Apo mutoro unoenda kwete "pakadzika", asi "pahupamhi".
- Nzvimbo dzekuyedza uko kumwe kunonoka kudiki kunogamuchirwa, asi kune zvirambidzo zvebhajeti, nekuti iyi bvunzo.
Panguva ino, ndeyemabasa aya atakaita AERODISK vAIR uye iri pavari yatiri kutarisa (zvakabudirira kusvika ikozvino). Zvichida izvi zvichachinja munguva pfupi, nekuti ... nyika haimire.
