Sawubona, bafundi bakaHabr. Ngalesi sihloko sivula uchungechunge oluzokhuluma nge-hyperconverged system AERODISK vAIR esiyithuthukisile. Ekuqaleni, sasifuna ukutshela konke mayelana nakho konke esihlokweni sokuqala, kodwa uhlelo luyinkimbinkimbi, ngakho-ke sizodla indlovu ngezingxenye.
Ake siqale indaba ngomlando wokudalwa kwesistimu, sihlole ohlelweni lwefayela le-ARDFS, okuyisisekelo se-vAIR, futhi sikhulume kancane mayelana nokumiswa kwalesi sixazululo emakethe yaseRussia.
Ezihlokweni ezizayo sizokhuluma ngemininingwane eminingi mayelana nezingxenye zezakhiwo ezihlukene (iqoqo, i-hypervisor, ibhalansi yomthwalo, isistimu yokuqapha, njll.), inqubo yokumisa, ukuphakamisa izinkinga zamalayisense, ukukhombisa ngokuhlukana ukuhlolwa kokuphahlazeka futhi, kunjalo, bhala mayelana nokuhlolwa komthwalo kanye ukulinganisa. Sizophinda sinikele ngendatshana ehlukile enguqulweni yomphakathi ye-vAIR.
Ingabe i-Aerodisk iyindaba mayelana nezinhlelo zokugcina? Noma kungani siqale ukwenza i-hyperconvergence kwasekuqaleni?
Ekuqaleni, umqondo wokudala i-hyperconvergence yethu weza kithi endaweni ethile cishe ngo-2010. Ngaleso sikhathi, kwakungekho Aerodisk noma izixazululo ezifanayo (commercial boxed hyperconverged systems) emakethe. Umsebenzi wethu wawulokhu okulandelayo: kusukela kusethi yamaseva anamadiski endawo, ahlanganiswe uxhumano nge-protocol ye-Ethernet, kwakudingeka ukudala isitoreji esinwetshiwe futhi kwethulwe imishini ebonakalayo kanye nenethiwekhi yesofthiwe lapho. Konke lokhu bekumele kuqaliswe ngaphandle kwezinhlelo zokugcina (ngoba ibingekho nje imali yezinhlelo zokulondoloza nehardware yayo, futhi besingakazisunguli ezethu izinhlelo zokugcina).
Sizame izixazululo eziningi zomthombo ovulekile futhi ekugcineni saxazulula le nkinga, kodwa isisombululo sasiyinkimbinkimbi kakhulu futhi kunzima ukuphinda. Ngaphandle kwalokho, lesi sixazululo besisesigabeni esithi “Ingabe siyasebenza? Ungathinti! Ngakho-ke, ngemva kokuxazulula leyo nkinga, asizange sithuthukise umqondo wokuguqula umphumela womsebenzi wethu ube umkhiqizo ophelele.
Ngemva kwaleso sigameko, sasuka kulo mbono, kodwa sasisenomuzwa wokuthi le nkinga yayixazululeka ngokuphelele, futhi izinzuzo zesixazululo esinjalo zazingaphezu kokusobala. Kamuva, imikhiqizo ekhishwe ye-HCI yezinkampani zakwamanye amazwe yaqinisekisa lo muzwa kuphela.
Ngakho-ke, maphakathi no-2016, sibuyele kulo msebenzi njengengxenye yokudala umkhiqizo ogcwele. Ngaleso sikhathi sasingakabi nabo ubudlelwano nabatshalizimali, ngakho kwadingeka sithenge isitendi sokuthuthukisa ezethu imali engenkulu kakhulu. Ngemva kokuqoqa amaseva asetshenzisiwe namaswishi ku-Avito, sangena ebhizinisini.
Umsebenzi oyinhloko kwakuwukudala okwethu, nakuba kulula, kodwa uhlelo lwethu lwefayela, olungasabalalisa ngokuzenzakalelayo nangokulinganayo idatha ngendlela yamabhulokhi abonakalayo enombolweni ye-nth yama-cluster node, axhunywe ngoxhumano nge-Ethernet. Ngesikhathi esifanayo, i-FS kufanele ikhule kahle futhi kalula futhi izimele ezimisweni eziseduze, i.e. bahlukaniswe ne-VAIR ngendlela “yendawo yokugcina izinto”.
Umqondo wokuqala we-vAIR
Sikuyekile ngamabomu ukusetshenziswa kwezixazululo zemithombo evulekile esezenziwe kakade yokuhlela isitoreji esinwetshiwe (i-ceph, i-gluster, i-luster nokunye okunjalo) ukuze sivune intuthuko yethu, njengoba sase sinolwazi oluningi lwephrojekthi nabo. Yiqiniso, lezi zixazululo ngokwazo zinhle kakhulu, futhi ngaphambi kokusebenza ku-Aerodisk sasebenzisa iphrojekthi yokuhlanganisa engaphezu kweyodwa. Kodwa kuyinto eyodwa ukwenza umsebenzi othize wekhasimende elilodwa, abasebenzi bezitimela futhi, mhlawumbe, ukuthenga ukwesekwa komthengisi omkhulu, futhi enye into ukudala umkhiqizo ophindaphindeka kalula ozosetshenziselwa imisebenzi ehlukahlukene, thina, umthengisi, angase azi ngathi thina ngeke. Ngenhloso yesibili, imikhiqizo ekhona yomthombo ovulekile ibingasifanele, ngakho-ke sinqume ukuzidalela isistimu yefayela esabalalisiwe.
Eminyakeni emibili kamuva, abathuthukisi abaningana (abahlanganisa umsebenzi ku-vAIR nomsebenzi wohlelo lokugcina lwe-Engine) bathole umphumela othile.
Ngo-2018, sase sibhale isistimu yefayela elula futhi sayifaka nge-hardware edingekayo. Uhlelo luhlanganise amadiski aphathekayo (asendaweni) asuka kumaseva ahlukene awayise echibini elilodwa eliyisicaba ngoxhumano lwangaphakathi futhi “awasike” abe amabhulokhi abonakalayo, bese kwakhiwa imishini yokuvimba enamazinga ahlukene okubekezelela amaphutha kusuka kumabhulokhi abonakalayo, lapho kwakhiwe khona lawo abonakalayo. futhi ibulawa kusetshenziswa izimoto ze-KVM hypervisor.
Asizange sizihluphe kakhulu ngegama lesistimu yefayela futhi salibiza ngamafuphi ngokuthi ARDFS (qagela ukuthi limelelani))
Lesi sibonelo sibukeka sisihle (hhayi ngokubonakalayo, vele, kwakungekho umklamo obonakalayo okwamanje) futhi ubonise imiphumela emihle mayelana nokusebenza nokukala. Ngemva komphumela wangempela wokuqala, simise le phrojekthi, sihlela indawo egcwele yokuthuthukiswa kanye nethimba elihlukile elibhekene ne-vAIR kuphela.
Ngaleso sikhathi, ukwakheka okujwayelekile kwesixazululo kwase kuvuthiwe, okungakenzeki izinguquko ezinkulu.
Ukungena ohlelweni lwefayela le-ARDFS
I-ARDFS iyisisekelo se-vAIR, esihlinzeka ngesitoreji sedatha esabalalisiwe, esibekezelela amaphutha kulo lonke iqoqo. Esinye sezici (kodwa hhayi kuphela) ezihlukile ze-ARDFS ukuthi ayisebenzisi noma yimaphi amaseva azinikele angeziwe ukuze uthole imethadatha nokuphatha. Lokhu kwacatshangelwa ukuthi kwenziwe lula ukucushwa kwesixazululo kanye nokuthembeka kwaso.
Isakhiwo sesitoreji
Kuwo wonke ama-node eqoqo, i-ARDFS ihlela ichibi elinengqondo kuzo zonke izikhala zediski ezitholakalayo. Kubalulekile ukuqonda ukuthi ichibi akukabi yidatha noma indawo efomethiwe, kodwa umaka nje, i.e. Noma yimaphi ama-node ane-vAIR efakiwe, lapho engezwa kuqoqo, engezwa ngokuzenzakalelayo echibini le-ARDFS okwabelwana ngalo futhi izinsiza zediski zibiwa ngokuzenzakalelayo kulo lonke iqoqo (futhi zitholakalela ukugcinwa kwedatha kwesikhathi esizayo). Le ndlela ikuvumela ukuthi wengeze futhi ususe ama-node endizeni ngaphandle komthelela ongathi sína ohlelweni oluvele lusebenza. Labo. uhlelo kulula kakhulu ukukala "ezitini", ukwengeza noma ukukhipha ama-node ku-cluster uma kunesidingo.
Amadiski abonakalayo (izinto zokugcina zemishini ebonakalayo) zengezwa phezu kwechibi le-ARDFS, akhiwe ngamabhulokhi abonakalayo angama-megabytes angu-4 ngosayizi. Amadiski abonakalayo agcina idatha ngokuqondile. Uhlelo lokubekezelela iphutha luphinde lusethwe ezingeni lediski elibonakalayo.
Njengoba kungenzeka ukuthi usuqagele kakade, ngokubekezelela iphutha kwesistimu engaphansi yediski, asisebenzisi umqondo we-RAID (Uhlu olungadingekile lwama-Disks azimele), kodwa sebenzisa i-RAIN (Uhlu olungadingekile lwamaNode azimele). Labo. Ukubekezelela amaphutha kuyalinganiswa, kuyazenzekela, futhi kulawulwa ngokusekelwe kumanodi, hhayi amadiski. Ama-Disks, yiqiniso, ayinto yokugcina izinto, wona, njengakho konke okunye, aqashwe, ungenza yonke imisebenzi ejwayelekile nawo, kuhlanganise nokuhlanganisa i-RAID ye-hardware yendawo, kodwa iqoqo lisebenza ngokuqondile kuma-node.
Esimeni lapho ufuna ngempela i-RAID (isibonelo, isimo esisekela ukwehluleka okuningi kumaqoqo amancane), akukho okukuvimbela ekusebenziseni izilawuli zendawo ze-RAID, nokwakha isitoreji esinwetshiwe kanye nesakhiwo se-RAIN phezulu. Lesi simo sibukhoma futhi sisekelwa yithi, ngakho-ke sizokhuluma ngaso esihlokweni esimayelana nezimo ezijwayelekile zokusebenzisa i-vAIR.
Izikimu Zokubekezelela Amaphutha Esitoreji
Kungaba nezikimu ezimbili zokubekezelela amaphutha kumadiski abonakalayo ku-vAIR:
1) Isici sokuphindaphinda noma ukuphindaphinda - le ndlela yokubekezelela amaphutha ilula njengenduku nentambo. Ukuphindaphinda okuvumelanayo kwenziwa phakathi kwamanodi anesici esingu-2 (amakhophi angu-2 ngeqoqo ngalinye) noma angu-3 (amakhophi angu-3, ngokulandelana). I-RF-2 ivumela i-virtual disk ukuthi imelane nokwehluleka kwe-node eyodwa kuqoqo, kodwa "idla" ingxenye yevolumu ewusizo, futhi i-RF-3 izomelana nokwehluleka kwamanodi angu-2 kuqoqo, kodwa igcine u-2/3 we ivolumu ewusizo ngezidingo zayo. Lolu hlelo lufana kakhulu ne-RAID-1, okungukuthi, idiski ebonakalayo elungiselelwe ku-RF-2 imelana nokwehluleka kwanoma iyiphi i-node eyodwa kuqoqo. Kulesi simo, yonke into izohamba kahle ngedatha futhi ngisho ne-I/O ngeke ime. Uma i-node ewile ibuyela kusevisi, ukutholwa kwedatha okuzenzakalelayo/ukuvumelanisa kuzoqala.
Ngezansi kunezibonelo zokusatshalaliswa kwedatha ye-RF-2 ne-RF-3 kumodi evamile futhi esimweni sokwehluleka.
Sinomshini obonakalayo onomthamo ongu-8MB wedatha ehlukile (ewusizo), esebenza kumanodi angu-4 e-vAIR. Kuyacaca ukuthi empeleni akunakwenzeka ukuthi kuzoba nevolumu encane kangaka, kodwa ngohlelo olubonisa i-logic yokusebenza kwe-ARDFS, lesi sibonelo siqondakala kakhulu. I-AB ingamabhulokhi angu-4MB aqukethe idatha eyingqayizivele yomshini wokubuka. I-RF-2 idala amakhophi amabili ala mabhulokhi A1+A2 kanye ne-B1+B2, ngokulandelana. Lawa mabhulokhi "abekwe ngaphandle" kuwo wonke ama-node, ukugwema ukuphambana kwedatha efanayo endaweni efanayo, okungukuthi, ikhophi A1 ngeke ibekwe endaweni efanayo nekhophi A2. Ngokufanayo ne-B1 ne-B2.
Uma enye yama-node ihluleka (isibonelo, i-node No. 3, equkethe ikhophi ye-B1), le khophi isebenze ngokuzenzakalelayo endaweni lapho ingekho ikhophi yekhophi yayo (okungukuthi, ikhophi ye-B2).
Ngakho-ke, i-virtual disk (kanye ne-VM, ngokufanele) ingasinda kalula ekuhlulekeni kwe-node eyodwa ohlelweni lwe-RF-2.
Uhlelo lokuphindaphinda, nakuba lulula futhi luthembekile, lunenkinga efanayo ne-RAID1 - asikho isikhala esanele esisebenzisekayo.
2) Sula ikhodi yekhodi noma ukususa ikhodi (okubuye kwaziwe ngokuthi “ukubhala amakhodi okungafuneki”, “ikhodi yokusula” noma “ikhodi yokungafuneki”) ikhona ukuze kuxazululwe inkinga engenhla. I-EC iwuhlelo lokuphindaphinda olunikeza ukutholakala kwedatha ephezulu ngesikhala esiphansi sediski uma kuqhathaniswa nokuphindaphinda. Umgomo wokusebenza kwalo mshini ufana ne-RAID 5, 6, 6P.
Lapho kufakwa ikhodi, inqubo ye-EC ihlukanisa ibhulokhi ebonakalayo (i-4MB ngokuzenzakalelayo) ibe "iziqephu zedatha" ezimbalwa ezincane kuye ngohlelo lwe-EC (isibonelo, isikimu esingu-2+1 sihlukanisa ibhulokhi ngayinye engu-4MB ibe yizingxenyana ezingu-2 2MB). Okulandelayo, le nqubo ikhiqiza "izigaxa zokulingana" "zezingxenyana zedatha" ezingekho nkulu kuneyodwa yezingxenye ezihlukaniswe ngaphambilini. Lapho iqoshwa, i-EC ikhiqiza izingcezu ezingekho ngokufunda idatha "esindile" kulo lonke iqoqo.
Isibonelo, idiski ebonakalayo enohlelo lwe-2 + 1 EC, olusetshenziswa kuma-cluster node angu-4, izomelana kalula nokwehluleka kwenodi eyodwa kuqoqo ngendlela efanayo ne-RF-2. Kulokhu, izindleko ze-overhead zizoba ngaphansi, ikakhulukazi, i-coefficient yamandla ewusizo ye-RF-2 ingu-2, futhi ku-EC 2+1 izoba ngu-1,5.
Ukuyichaza kalula, ingqikithi iwukuthi ibhulokhi ebonakalayo ihlukaniswe ngo-2-8 (kungani kusuka ku-2 kuya ku-8, bheka ngezansi) "izingcezu", futhi kulezi zingcezu "izingcezu" zokulingana kwevolumu efanayo zibalwa.
Ngenxa yalokho, idatha nokulingana kusatshalaliswa ngokulinganayo kuwo wonke ama-node eqoqo. Ngesikhathi esifanayo, njengokuphindaphinda, i-ARDFS isakaza ngokuzenzakalelayo idatha phakathi kwama-node ngendlela yokuvimbela idatha efanayo (amakhophi edatha kanye nokulingana kwawo) ukuthi agcinwe endaweni efanayo, ukuze kuqedwe ithuba lokulahlekelwa idatha efanele. eqinisweni lokuthi idatha kanye nokulinganisa kwakho kuzogcina kungazelelwe ku-node eyodwa yokugcina ehlulekayo.
Ngezansi kunesibonelo, ngomshini ofanayo ongu-8 MB namanodi angu-4, kodwa ngohlelo lwe-EC 2+1.
Amabhulokhi A no-B ahlukaniswe abe izingcezu ezimbili zika-2 MB ngayinye (ezimbili ngenxa yokuthi 2+1), okungukuthi, A1+A2 kanye no-B1+B2. Ngokungafani ne-replica, i-A1 ayiyona ikhophi ye-A2, i-virtual block A, ihlukaniswe izingxenye ezimbili, efanayo ne-block B. Sekukonke, sithola amasethi amabili we-4MB, ngalinye eliqukethe izingcezu ezimbili ze-MB. Okulandelayo, kulelo nalelo sethi, i-parity ibalwa ngevolumu engekho ngaphezu kwesiqephu esisodwa (okungukuthi 2 MB), sithola izingcezu ezengeziwe ze-parity + 2 (AP ne-BP). Sekukonke sinedatha engu-4×2 + 2×2 isilinganiso.
Okulandelayo, izingcezu "zibekwe" phakathi kwamanodi ukuze idatha ingaphambanisi nokulingana kwazo. Labo. I-A1 ne-A2 ngeke zibe ku-node efanayo ne-AP.
Uma kwenzeka ukwehluleka kwe-node eyodwa (isibonelo, futhi yesithathu), i-block B1 ewile izobuyiselwa ngokuzenzakalelayo kusuka ku-BP parity, egcinwe ku-node No. 2, futhi izosebenza ku-node lapho kukhona khona. akukho B-parity, i.e. ingxenye ye-BP. Kulesi sibonelo, le nodi No. 1
Nginesiqiniseko sokuthi umfundi unombuzo:
"Yonke into oyichazile kade yasetshenziswa yizimbangi kanye nezixazululo zomthombo ovulekile, yini umehluko phakathi kokusetshenziswa kwakho kwe-EC ku-ARDFS?"
Futhi-ke kuzoba nezici ezithakazelisayo ze-ARDFS.
Sula amakhodi ngokugxila ekululameni
Ekuqaleni, sinikeze isikimu se-EC X+Y esivumelana nezimo, lapho u-X elingana nenombolo esuka ku-2 kuye ku-8, futhi u-Y elingana nenombolo esuka ku-1 kuye ku-8, kodwa njalo ingaphansi noma ilingana no-X. Lolu hlelo lunikeziwe. ukuguquguquka. Ukwandisa inani lezingcezu zedatha (X) lapho i-block ebonakalayo ihlukaniswa khona ivumela ukunciphisa izindleko eziphezulu, okungukuthi, ukwandisa isikhala esisebenzisekayo.
Ukwandisa inani lama-parity chunks (Y) kukhulisa ukuthembeka kwediski ebonakalayo. Uma inani elingu-Y likhulu, amanodi amaningi kuqoqo angahluleka. Yiqiniso, ukukhulisa umthamo wokulinganisa kunciphisa inani lamandla asebenzisekayo, kodwa lokhu kuyinani lokukhokhela ukwethembeka.
Ukuncika kokusebenza kumasekethe e-EC kucishe kuqonde: lapho "izingcezu" eziningi, ukusebenza kwehla; lapha, vele, umbono olinganiselayo uyadingeka.
Le ndlela ivumela abalawuli ukuthi balungiselele isitoreji esinwetshiwe ngokuguquguquka okukhulu. Ngaphakathi kwechibi le-ARDFS, ungasebenzisa noma yiziphi izinhlelo zokubekezelela amaphutha kanye nezinhlanganisela zazo, okuyinto, ngokubona kwethu, futhi iwusizo kakhulu.
Ngezansi kunethebula eliqhathanisa nezikimu ezimbalwa (akuzikho zonke ezingenzeka) ze-RF ne-EC.
Ithebula libonisa ukuthi ngisho nenhlanganisela ye-"terry" EC 8+7, evumela ukulahlekelwa ama-node angu-7 ngesikhathi esisodwa, "idla" indawo engasetshenziswa kakhulu (1,875 ngokumelene no-2) kunokuphindaphinda okujwayelekile, futhi ivikela izikhathi ezingu-7 kangcono. , okwenza le ndlela yokuvikela, nakuba iyinkimbinkimbi kakhulu, ithandeka kakhulu ezimweni lapho kudingekile ukuqinisekisa ukwethembeka okuphezulu ezimweni zesikhala esilinganiselwe sediski. Ngesikhathi esifanayo, udinga ukuqonda ukuthi konke "ukuhlanganisa" ku-X noma ku-Y kuzoba ngaphezulu kokusebenza okwengeziwe, ngakho-ke kunxantathu phakathi kokuthembeka, ukonga nokusebenza udinga ukukhetha ngokucophelela. Ngalesi sizathu, sizonikela ngendatshana ehlukile ukuze sisule usayizi wekhodi.
Ukuthembeka nokuzimela kwesistimu yefayela
I-ARDFS isebenza endaweni kuwo wonke ama-node eqoqo futhi iwavumelanisa kusetshenziswa izindlela zayo ngokusebenzisa ukuxhumana kwe-Ethernet okuzinikele. Iphuzu elibalulekile ukuthi i-ARDFS ayivumelanisi ngokuzimela idatha kuphela, kodwa futhi imethadatha ehlobene nokugcinwa. Ngenkathi sisebenza ku-ARDFS, ngesikhathi esisodwa safunda izixazululo eziningi ezikhona futhi sathola ukuthi eziningi zivumelanisa imeta yesistimu yefayela kusetshenziswa i-DBMS esabalalisiwe yangaphandle, esibuye siyisebenzisele ukuvumelanisa, kodwa ukulungisa kuphela, hhayi imethadatha ye-FS (mayelana nalokhu kanye nezinye izinhlelo ezingaphansi ezihlobene. esihlokweni esilandelayo).
Ukuvumelanisa imethadatha ye-FS kusetshenziswa i-DBMS yangaphandle, vele, kuyisixazululo esisebenzayo, kodwa-ke ukuvumelana kwedatha egcinwe ku-ARDFS kuzoncika ku-DBMS yangaphandle nokuziphatha kwayo (futhi, uma sikhuluma ngokungananazi, iyintokazi engenangqondo), okuthi umbono wethu mubi. Kungani? Uma imethadatha ye-FS ilimala, idatha ye-FS ngokwayo ingabuye ishiwo "sala kahle," ngakho-ke sinqume ukuthatha indlela eyinkimbinkimbi kodwa enokwethenjelwa.
Senze isistimu engaphansi yokuvumelanisa imethadatha ye-ARDFS ngokwethu, futhi iphila ngokuzimela ngokuphelele kumasistimu angaphansi aseduze. Labo. alukho olunye uhlelo olungaphansi olungakonakalisa idatha ye-ARDFS. Ngokombono wethu, lena indlela ethembeke kakhulu futhi elungile, kodwa isikhathi sizosho ukuthi lokhu kunjalo ngempela. Ngaphezu kwalokho, kunenzuzo eyengeziwe ngale ndlela. I-ARDFS ingasetshenziswa ngokuzimela kwe-vAIR, njengesitoreji eseluliwe, esizosisebenzisa ngokuqinisekile emikhiqizweni ezayo.
Ngenxa yalokho, ngokwakha i-ARDFS, sithole isistimu yefayela eguquguqukayo nethembekile enikeza ukukhetha lapho ongonga khona umthamo noma unikeze yonke into ngokusebenza, noma wenze isitoreji esithembeke kakhulu ngezindleko ezizwakalayo, kodwa wehlise izidingo zokusebenza.
Ngokuhambisana nenqubomgomo elula yelayisense kanye nemodeli yokulethwa eguquguqukayo (uma ubheka phambili, i-vAIR ilayisensi nge-node, futhi ilethwa njenge-software noma njengephakheji yesofthiwe), lokhu kukuvumela ukuba wenze ngokunembe kakhulu isixazululo esivumelana nezinhlobonhlobo zezidingo zamakhasimende futhi bese ugcina kalula lokhu kulinganisela.
Ubani odinga lesi simangaliso?
Ngakolunye uhlangothi, singasho ukuthi sekukhona abadlali emakethe abanezixazululo ezingathi sína emkhakheni we-hyperconvergence, futhi kulapho siphokophele khona. Kubonakala sengathi lesi sitatimende siyiqiniso, KODWA...
Ngakolunye uhlangothi, lapho siphumela emasimini futhi sixhumana namakhasimende, thina nabalingani bethu siyabona ukuthi akunjalo neze. Kunemisebenzi eminingi ye-hyperconvergence, kwezinye izindawo abantu bebengazi nje ukuthi izixazululo ezinjalo zikhona, kwezinye zibonakala zibiza kakhulu, kwezinye kube nokuhlolwa okungaphumeleli kwezinye izixazululo, kanti kwezinye benqabela ukuthenga nhlobo ngenxa yezinhlawulo. Ngokuvamile, insimu yaphenduka yangalinywa, ngakho sahamba sayokhulisa inhlabathi engakazalwa))).
Inini isistimu yokugcina ingcono kune-GCS?
Njengoba sisebenza nemakethe, sivame ukubuzwa ukuthi kungcono nini ukusebenzisa uhlelo lwakudala olunezinhlelo zokugcina, futhi nini ukusebenzisa i-hyperconvergent? Izinkampani eziningi ezikhiqiza i-GCS (ikakhulukazi lezo ezingenawo amasistimu okugcina kumaphothifoliyo azo) zithi: “Amasistimu okugcina aphelelwa yisikhathi, ahlangana kakhulu kuphela!” Lesi isitatimende esinesibindi, kodwa asibonisi ngokuphelele iqiniso.
Eqinisweni, imakethe yesitoreji empeleni iqhubekela ku-hyperconvergence kanye nezixazululo ezifanayo, kodwa kuhlale kukhona "kodwa".
Okokuqala, izikhungo zedatha kanye nengqalasizinda ye-IT eyakhiwe ngokohlelo lwakudala olunezinhlelo zokugcina azikwazi ukwakhiwa kabusha kalula, ngakho ukuthuthukiswa kanye nokuqedwa kwengqalasizinda enjalo kuseyifa leminyaka engu-5-7.
Okwesibili, ingqalasizinda esakhiwayo njengamanje ingxenye enkulu (okusho ukuthi i-Russian Federation) yakhiwe ngokuvumelana nohlelo lwe-classical isebenzisa izinhlelo zokugcina, futhi hhayi ngoba abantu abazi mayelana ne-hyperconvergence, kodwa ngoba imakethe ye-hyperconvergence entsha, izixazululo futhi izindinganiso azikakasungulwa , abantu be-IT abakaqeqeshwa, banolwazi oluncane, kodwa badinga ukwakha izikhungo zedatha lapha futhi manje. Futhi lo mkhuba uzohlala eminye iminyaka engu-3-5 (bese kuba elinye ifa, bheka iphuzu 1).
Okwesithathu, kunomkhawulo wobuchwepheshe kuphela ekubambezelekeni okuncane okwengeziwe kwama-millisecond angu-2 ngokubhala ngakunye (ngaphandle kwenqolobane yasendaweni, kunjalo), okuyizindleko zesitoreji esabalalisiwe.
Hhayi-ke, masingakhohlwa ngokusetshenziswa kwamaseva amakhulu angokwenyama athanda ukukalwa okuqondile kwesistimu engaphansi yediski.
Kunemisebenzi eminingi edingekayo nedumile lapho amasistimu okugcina aziphatha kangcono kune-GCS. Lapha, yiqiniso, labo abakhiqizi abangenazo izinhlelo zokugcina kuphothifoliyo yomkhiqizo wabo ngeke bavumelane nathi, kodwa silungele ukuphikisana ngokunengqondo. Vele, thina, njengabathuthukisi bayo yomibili imikhiqizo, sizoqhathanisa amasistimu okugcina kanye ne-GCS kwenye yezincwadi zethu zesikhathi esizayo, lapho sizobonisa khona ngokucacile ukuthi yikuphi okungcono ngaphansi kwaziphi izimo.
Futhi izixazululo ze-hyperconverged zizosebenza kuphi kangcono kunezinhlelo zokugcina?
Ngokusekelwe kumaphuzu angenhla, kungafinyelelwa iziphetho ezintathu ezisobala:
- Lapho ama-milliseconds engeziwe angu-2 wokubambezeleka kokurekhoda, okwenzeka ngokuqhubekayo kunoma yimuphi umkhiqizo (manje asikhulumi ngama-synthetics, ama-nanosecond angaboniswa kuma-synthetics), awagxeki, i-hyperconvergent ifanelekile.
- Lapho umthwalo ovela kumaseva amakhulu omzimba ungaguqulwa ube ama-virtual amaningi amancane futhi usatshalaliswe phakathi kwama-node, i-hyperconvergence nayo izosebenza kahle lapho.
- Lapho ukukala okuvundlile kubaluleke kakhulu kunokulinganisa okuqondile, i-GCS izokwenza kahle lapho futhi.
Yiziphi lezi zixazululo?
- Zonke izinsiza ezijwayelekile zengqalasizinda (isevisi yohlu lwemibhalo, i-imeyili, i-EDMS, amaseva wefayela, amasistimu we-ERP amancane noma aphakathi nendawo kanye ne-BI, njll.). Lokhu sikubiza ngokuthi “ikhompyutha evamile.”
- Ingqalasizinda yabahlinzeki bamafu, lapho kudingekile khona ukukhulisa ngokushesha nangokujwayelekile ngokuvundlile futhi kalula "ukusika" inombolo enkulu yemishini ebonakalayo yamakhasimende.
- Ingqalasizinda yedeskithophu eyi-Virtual (VDI), lapho imishini eminingi yabasebenzisi emincane isebenza futhi “intante” buthule phakathi kweqoqo elifanayo.
- Amanethiwekhi egatsha, lapho igatsha ngalinye lidinga ingqalasizinda evamile, ebekezelela amaphutha, kodwa engabizi yemishini ebonakalayo engu-15-20.
- Noma iyiphi ikhompyutha esabalalisiwe (isibonelo, amasevisi amakhulu edatha). Lapho umthwalo ungangeni “ekujuleni”, kodwa “ngobubanzi”.
- Izimo zokuhlola lapho ukubambezeleka okuncane okwengeziwe kwamukelekayo, kodwa kunemikhawulo yebhajethi, ngoba lezi zivivinyo.
Okwamanje, kungenxa yale misebenzi senze i-AERODISK vAIR futhi sigxile kuyona (ngempumelelo kuze kube manje). Mhlawumbe lokhu kuzoshintsha maduze, ngoba... umhlaba awumi.
Ngakho...
Lokhu kuqeda ingxenye yokuqala yochungechunge olukhulu lwezihloko; esihlokweni esilandelayo sizokhuluma ngokwakhiwa kwesixazululo kanye nezingxenye ezisetshenzisiwe.
Samukela imibuzo, iziphakamiso kanye nezingxabano ezakhayo.
