Yintoni engenakwenza uRaid 0 okanye abanye?
Njengayo nayiphi na enye indlela yekhompyutheni, i-Raid 0 inemida yayo, enye yazo kukuba akusiyo ishaneli yokukhusela idatha, ichaza ulwazi, kodwa ayikhuseli, zombini iingcamango zihluke. Apho intsholongwane ingenza umonakalo ofanayo kwi-autonomous hard drive, ngokungathi iRaid ingene. Ke ngoko, ukuba awunayo inkqubo yokhuseleko, ulwazi luya kuvezwa ngokulinganayo.
Ngokufanayo, isantya esiphezulu asiqinisekiswanga nokuba, kukho ulungelelwaniso olunokwenziwa ngumsebenzisi, nangona kungekhona zonke izicelo okanye imidlalo enokusebenza kakuhle kwi-Raid. Ngokubanzi, akuyi kuba luncedo ekusebenziseni ii-hard drives ezi-2 endaweni ye-1 ukubamba idatha ngendlela yokwahlula.
Izinto ezingeloncedo ngoRaid 0
Kwakhona, i-Raid ayiqinisekisi ukubuyiswa kwentlekele, kwaye njengoko kuyaziwa, kukho izicelo ezikwazi ukubuyisela iifayile kwi-hard drive kwimeko embi. Kodwa iRaid ifuna abaqhubi abahlukeneyo nabathile, kwaye abahambelani nezicelo ezinjalo. Ke ngoko, kwimeko yokungaphumeleli kwekhonkco okanye iidiski ezininzi, inokuba yidatha engafumanekiyo.
Ngakolunye uhlangothi, ukufuduka kolwazi kuyinkimbinkimbi, ngelixa ukudibanisa idiski kunye nenkqubo yokusebenza kulula, kunye neRaid epheleleyo ukuya kwelinye, ngumsebenzi onzima ukuba awunazo izixhobo ezibonisiweyo. Oko kukuthi, ukufuduka iifayile ukusuka kwisistim enye ukuya kwenye ukuyihlaziya kunokuba yinto engenakugqithiswa.
Ekugqibeleni, kukho iindleko zokuqala, nangona ukuphumeza i-Raid nge-2 disks kulula, ukuba ufuna ukwenza iiseti eziyinkimbinkimbi kunye ne-rhetorical, izinto ziba nzima. Okokuthi, ukuba kukho iidiski ezininzi, ixabiso eliphezulu, kwaye ukuba inkqubo inzima kakhulu, kuya kufuneka ngaphezulu.
Ngawaphi amanqanaba eRaid akhoyo?
Okwangoku, kuyenzeka ukuba ufumane iintlobo ezahlukeneyo zeRaid kwimarike, nangona ezi zahlulwe ngokwamanqanaba asemgangathweni, afakwe kwindlwane kunye nalawo anelungelo. Apho awona maxesha amaninzi asetyenziswa ngabasebenzisi abazimeleyo kunye neenkampani ezincinci, zisemgangathweni kunye neendawo zokuhlala, ekubeni inxalenye enhle yezixhobo eziphezulu zinokuyenza ngaphandle kokufaka nayiphi na into eyongezelelweyo.
Ngokuchasene noko, amanqanaba obunikazi asetyenziswa kuphela ngabadali ngokwabo okanye abo banikela ngolu hlobo lwenkonzo. Ngoku, kwinqanaba lokucwangcisa, iintlobo ezahlukeneyo zingasetwa ngokuxhomekeke kwinjongo. Ukukwazi ukubenza lula, ukuba ufuna ukwandisa ukusebenza, okukhethwa kukho i-Raid 0, ngelixa ukubonelela ngokhuseleko lwedatha enkulu, okufanelekileyo kukunyusa i-Raid 1.
Kwaye kwimfuno yokuba nazo zombini iindlela, yonke iRaid yavela, efana nothotho 5, 6, 10 kunye nokwahluka kwayo. Ngokuxhomekeke kwinani leediski onazo, ungasebenzisa enye okanye enye. Apho uchungechunge lwe-0 kunye ne-1 lufikeleleke kakhulu, kuba kuphela iidiski ezi-2 ezifunekayo (ubuncinci, ngenxa yokuba zinokuba zingaphezulu) kwaye njengezikali zedatha, zilayishe kwenye, de zifikelele kwimfuno yediski ephezulu. Kodwa makhe sijonge nganye kwezi zixhobo:
Ugqogqo luka-0
Njengokuqala kweRaid, into ebizwa ngokuba yinqanaba le-0 okanye iseti eyahlulwe yazalwa. Kule nto akukho mfuneko yokuphindaphinda idatha, ekubeni umsebenzi wale nqanaba kukusasaza idatha egciniweyo phakathi kwee-hard drives ezahlukeneyo eziqhagamshelwe kwikhompyuter. Injongo yalo kukubonelela ngesantya sokufikelela kulwazi olugcinwe kwiidiski, ekubeni ulwazi luhanjiswa ngokulinganayo kubo ukunika ukufikelela kwangaxeshanye, kunye nomthamo omkhulu wedatha kunye neeyunithi zayo ngokufanayo.
Uhlaselo lwe-0 aluqulathanga idatha okanye i-rhetorical data, ngoko ke, ukuba enye yeeyunithi ezigciniweyo ziyaphuka, yonke idatha engaphakathi kuyo iya kulahleka, ngaphandle kokuba kukho iikopi ezigciniweyo zangaphandle zoqwalaselo oluxeliweyo.
Ukuba ufuna ukwenza i-RAID 0, kufuneka uqwalasele ubungakanani bee-hard drives ezizenzayo. Ibhekisa kwi-hard drive encinci eqhuba isithuba esongezelelweyo kwi-RAID. Kwaye ukuba une-1TB drive kunye ne-500GB ye-drive kuqwalaselo, ubungakanani beseti yokusebenza iya kuba yi-1TB, ithatha i-500GB drive kunye nenye i-500GB ye-1TB drive. Ngoko ke, kukulungele ukwamkela iidiski zobukhulu obufanayo ukwenzela ukuba kusetyenziswe yonke indawo ekhoyo kwisethi eyiliweyo.
Ugqogqo luka-1
Ngokwenxalenye yayo, ukucwangciswa kwe-Raid 1, okubizwa ngokuba yi-mirroring, yenye yezona zinto ziqhelekileyo ezisetyenziselwa ukubonelela nge-redundancy data kunye nokunyamezela impazamo. Kwimeko apho, into eyenziwayo kukuvelisa ivenkile kunye nedatha ephindwe kabini kwii-hard drives ezi-2, okanye iiseti ezi-2 zezi. Xa ugcina isiqwenga sedatha, iphinda iphindwe ngokukhawuleza kwiyunithi yesibuko sayo, kwaye ngoko ibe nemixholo emi-2 yedatha efanayo.
Ngokujonga inkqubo yokusebenza, uneyunithi enye kuphela yokugcina, apho ungaya khona ukufikelela kwidatha kuyo. Nangona kunjalo, kwimeko yokungaphumeleli, idatha kwi-replicated drive iya kukhunjulwa ngokuzenzekelayo. Ikwasebenza ekwandiseni isantya sokufunda, kuba ulwazi lunokufundwa ngaxeshanye kuzo zombini iiyunithi ezibonisiweyo.
Ugqogqo luka-2
Uhlaselo lwenqanaba lesi-2 alisetyenziswa rhoqo, kuba lusekwe ngokusisiseko kugcino olucwangciswe kakuhle kwiidiski ezininzi kwinqanaba lebit. Kwaye kwangaxeshanye, ivelisa ikhowudi yempazamo yokusasazwa kwedatha kwaye igcinwe kwiiyunithi ezikhethekileyo kule njongo. Ngale ndlela zonke iidiski evenkileni ziyakwazi ukubeka iliso kwaye zilungelelaniswe ngokufunda nokubhala idatha.
Ekubeni ngoku iidiski ziza kunye nenkqubo yokukhangela impazamo, olu lungelelwaniso alufanelekanga, kwaye kuphela inkqubo yokulinganisa isetyenziswa.
Ugqogqo luka-3
Uhlaselo lwe-3 alusetyenziswanga okwangoku, kwaye lubandakanya ulwahlulo lwedatha kwinqanaba le-byte kwiiyunithi ezahlukeneyo ezenza i-Raid, ngaphandle kweyodwa apho ulwazi lokulingana lugcinwe oluvumela ukuba le datha idibaniswe xa ifundwa. Ngaloo ndlela, i-byte nganye egciniweyo ine-1 eyongezelelweyo ye-parity bit evumela ukuba iimpazamo zichongwe kunye nedatha ukuba ibuyiselwe xa kwenzeka ilahleko yeyunithi.
Inenzuzo yokuba idatha yahlulwe kwiidiski ezininzi kwaye ivumela ukufikelela ngokukhawuleza kulwazi, nje ukuba kukho iidiski ezihambelanayo kuyo. Uqwalaselo lwayo lufuna ubuncinci ii-hard drives ezi-3.
Ugqogqo luka-4
Ikwathobela indawo yokugcina idatha eyahlulwe kwiibhloko phakathi kweediski, kodwa ishiya enye yezi ukugcina amasuntswana okulingana. Umahluko wayo obalulekileyo ngokumalunga ne-Raid 3 ixhomekeke kwinto yokuba xa iyunithi ilahlekile, idatha inokwakhiwa kwakhona ngexesha langempela ngokubonga kwi-parity bits.
Ngokusisiseko ijoliswe ekugcinweni kweefayile ezinkulu, ngaphandle kokuphindaphinda kwabo, nangona ukurekhoda kwedatha kucotha ngenxa yesidingo sokwenza oku kubalwa komlinganiso ngexesha ngalinye into irekhodwa.
Ugqogqo luka-5
Uhlaselo lwe-5 lukwabizwa ngokuba yinkqubo esasazwayo ngokulinganayo; namhlanje isetyenziswa rhoqo ngaphezu kwamanqanaba 2, 3 kunye ne-4, ngokukodwa kwizixhobo zeNAS. Ulwazi lugcinwa lwahlulwe kwiibhloko ezisasazwa phakathi kwee-hard drives ezenza iRaid; ngokunjalo nokuvelisa ibhloko yomlinganiso ukuze kuqinisekiswe ukungasebenzi, kunye nokwakha ngokutsha ulwazi xa kunokwenzeka ukuba i-hard disk yonakale.
Wathi isikhongozeli ngababini uya kugcinwa iyunithi ngaphandle kwedatha ebandakanyekayo kubalwa, nale ulwazi ukulingana ziya kugcinwa kwi disk eyahlukileyo, apho iibhloko ulwazi olunxulumeneyo.
Ngokufanayo, ubuncinane beeyunithi zokugcina ezi-3 ezifunekayo, ukwenzela ukuba kuqinisekiswe ukuphindaphinda ngokulinganayo, kwaye kuya kunyamezela kuphela ukungaphumeleli kwiyunithi enye ngexesha. Ukuba i-2 yezi ziphulwe ngaxeshanye, ulwazi lokulingana luya kulahleka, kwaye ubuncinane enye yeebhloko zedatha ezibandakanyekayo. Kukwakho neRaid 5E eyahlukileyo, eyenzelwe ukubeka i-backup hard drive kunye nokunciphisa ixesha lokwakha kwakhona, kwimeko yokusilela kwenye yezona ziphambili.
Ugqogqo luka-6
Ukuhlaselwa kwe-6 kukwandiswa kwe-5, apho enye ibhloko yezibini yongezwa kwi-2 xa iyonke. Ngale nto, inkqubo iya kunyamezela ukungaphumeleli ukuya kwiiyunithi zokugcina ze-2, ngoko ke, ukuya kwiiyunithi ze-2 ezifunekayo ukwenza i-Raid 4E; ekwavelisa ukwahluka kwayo kwe-6E ngenjongo efanayo ne-6E.
Ugqogqo luka-10
I-Raid 10 ithathwa njengomanyano lwe-Raid 0 kunye ne-1, equlunqe umthamo omnye; apho inkqubo yokusebenza okuphezulu kunye nokungafuneki kufezekiswa. Kule meko, ukucwangciswa kwayo kufuna ubuncinane iidiski ze-4, ezinokuthi zicingelwe njenge-Raid 6, kodwa ngokusebenza ngakumbi.
Lo mbono awukho ubuxoki ngokupheleleyo, kuba ngokuqinisekileyo, ufuna ukuphucula ukubhala nokufunda kwi-Raid 5 okanye i-6, nangona idiski enye kuphela ingaphumeleli. Oku kungenxa yokuba iidiski ezi-2 ziqulethe idatha ye-A1 kunye ne-2 yolwazi lwe-A2. Kwaye kwimeko yokungaphumeleli kwediski kunye ne-A1 kunye nenye ene-A2, kuya kwenzeka ukuqhubeka nokusebenza kuba kukho iidiski ezi-2 kunye ne-A1 kunye ne-A2 esele. Kwaye ukuba zombini iidiski kunye ne-A1 okanye i-A2 ziyasilela, umthamo uya kuba ungafikeleleki njengoko isiqingatha sedatha yayo silahlekile.
AmaNqanaba oNgqongileyo
Emva kokubona amanqanaba e-Raid asisiseko kunye nokusetyenziswa kwawo, siza kuxubusha ngokufutshane amanqanaba afakwe kwindlwane; Kuqikelelwa ukuba, amanqanaba anjalo abhekiselele kwiinkqubo ezinomgangatho osisiseko we-RAID, kodwa kwangaxeshanye ziqulathe amanye amanqanaba asezantsi abonelela ngokusebenza koqwalaselo olwahlukileyo.
Ngale ndlela, iileya ezahlukeneyo zeRaid zibonakaliswa, zonke ziyakwazi ukwenza ngaxeshanye imisebenzi ethile eqhelekileyo yamanqanaba asisiseko, kwaye oku, ukudibanisa amandla okufikelela kokufunda ngokukhawuleza kunye neRaid 0 kunye nokungafuneki kwento eyi-1. , ukuyiqonda ngcono, makhe sibone eyona ixhaphakileyo ngoku:
ugqogqa 0 + 1
Olu Raid lunokufumaneka kwimarike njengeRaid 01 okanye isibuko sokwahlulahlula; kwaye ngokusisiseko ibhekisa kwinqanaba eliphambili lohlobo lwe-Raid 1, kunye nemisebenzi yokuphindaphinda idatha ekhoyo kwinqanaba lokuqala kunye nelesibini. Ngexesha elifanayo, kuya kubakho i-Raid 0 sublevel enemisebenzi efanayo ehambelana nayo, oko kukuthi, ukugcina idatha esasazwa phakathi kweeyunithi ezikhoyo kuyo.
Ngaloo ndlela, inqanaba eliphakathi lifunyenwe kunye nomsebenzi wesibuko esifanayo kunye ne-sublevels kunye nomsebenzi wokwahlula ulwazi. Ngale nto, ukuba i-hard drive iyasilela, idatha iya kuhlala ingatshintshi kwaye ikhuselwe kwesinye isibuko seRaid 0.
Le nkqubo ibika njengentlupheko ephambili, i-scalability yayo, xa idibanisa i-disk eyongezelelweyo kwi-sublevel, kuya kufuneka kwakhona ukwenza okufanayo kwenye. Ukongezelela, ukunyamezela kwesiphoso kuya kuvumela ukuphuka kwediski eyahlukileyo kwinqanaba eliphantsi ngalinye, okanye i-2 kwinqanaba elingaphantsi elifanayo, kodwa kungekhona enye indibaniselwano, kuba idatha iya kulahleka.
ugqogqa 1 + 0
Njengoko kuphawuliwe kwisihloko sayo, yimeko echaseneyo, edla ngokubizwa ngokuba yiRaid 10 okanye ulwahlulo lwesipili; apho kuya kubakho inqanaba eliphakathi lohlobo lwe-Raid 0, kwaye olwahlula idatha egciniweyo phakathi kwamanqanaba ahlukeneyo. Kwaye kwangaxeshanye, kuya kubakho iintlobo ezahlukeneyo ze-1 sublevels, ezinoxanduva lokuphindaphinda idatha kwii-hard drives ngaphakathi.
Ukuba ukunyamezela kwesiphoso kunikwe, oku kuya kuvumela ukuphulwa kwazo zonke iidiski ze-sublevel, ngaphandle komnye wabo, kuba yimfuneko ukuba ubuncinane idiski enye igcinwe kwimpilo entle kwi-sublevels nganye, ngenjongo yokungalahlekelwa kolwazi olugcinwe apho.
Ugqogqo luka-50
Kuyenzeka ukwenza imidibaniso emininzi ukusuka kwiRaid 0, de kube kukufumana ukuphindaphindeka okuphezulu, ukuthembeka okukhulu kunye nesantya. Kule meko, kunye ne-Raid 50, ethobela inqanaba eliphakathi kwi-Raid 0 eyenzelwe ukwahlula i-data ye-sublevels eqwalaselwe njengenqanaba lesi-5, kunye ne-3 hard drives zabo.
Ukwenza oku, ibhloko nganye yeRaid 5 inikezela ngeseti yedatha kunye nokulingana kwayo. Kule meko, i-hard disk inokungaphumeleli kwi-Raid 5 nganye, kwaye kunjalo iya kuqinisekisa ingqibelelo yedatha, ngelixa ukuba ingaphumeleli ngakumbi, idatha egcinwe ngaphakathi kwayo iya kulahleka.
ugqogqa 100 yaye 101
Kufuneka kuqatshelwe kule meko ukuba awukwazi nje ukuba nomthi we-2-level, kodwa i-3, injalo imeko ye-Raid 100 okanye i-1 + 0 + 0 isiphakamiso. Oku kubandakanya i-2 sublevels ye-Raid 1+0 eyahlulwe ngokulandelelana kwinqanaba eliphakathi kwi-Raid 0. Ngokunjalo, i-Raid 1+0+1 inokudityaniswa, yenziwe ngamanqanaba ahlukeneyo e-1+0 ebonakaliswe yi-Raid 1 njengesiseko. .
Kule nto, isantya sokufikelela kwayo kunye nokuphindaphinda kuya kufikelela kumanqanaba amahle kakhulu, achaza ukunyamezela okulungileyo ukujongana nokungaphumeleli okunokwenzeka, nangona inani leediski eziza kusetyenziswa likhulu xa kuthelekiswa nendawo ekhoyo.
Khetha iRaid
Ngoku, emva kokubona iindidi ezahlukeneyo kunye namanqanaba eRaid, ukuqala kwi-Raid yokuqala ye-0, umngeni uhlala umisela indlela yokukhetha enye yezi. Ewe, sele kubonisiwe ukuba amawaka okudibanisa angenziwa, okwenza isigqibo sokukhetha inkqubo efanelekileyo okanye eyona nto inzima kakhulu. Ukuba une disks ezininzi, ungakhetha ukwenza Raid 1+0, 0+1, 50, 60 kunye ezahlukeneyo ezahlukeneyo.
Ngaloo ndlela, ukuba ukuququzelela ukhetho, i-Raid calculators ziyafumaneka kwiwebhu, ezinceda ngezibalo eziyimfuneko. Kwakhona, kunomdla ukwazi ukuba kukho abalawuli abavumela umsebenzisi ukuba aqwalasele idiski ukuyeka. Eyona nto ingaphezulu kokudibanisa idiski ngaphandle kokuyisebenzisa kwaye ukuyiqala kwimeko yokusilela okunokwenzeka kwenye idiski.
Emva koko yinkqubo yokwakhiwa kwakhona kweRaid 0 ukuba umlawuli athathele ingqalelo ngokuzenzekelayo, xa efumanisa idiski ethotyiweyo. Phakathi kwemisebenzi ebaluleke kakhulu xa iRaid ifakiwe kukwenza uhlolo olungqongqo lwemeko yeediski; kuba ukuphindwa kabini akuthethi ukuba imeko yedatha egcinwe ngaphakathi iyakuhoywa.
Oku kungenxa yokuba zonke iidiski zinokuthotywa, ezifuna ukuphononongwa ukuze kubonwe iingxaki ezinokwenzeka. Oku kukwabalulekile xa idiski ingaphumeleli kwaye kufuneka itshintshwe ngokukhawuleza, ekubeni inomjikelo wobomi oluncedo, kwaye ukuba imodeli efanayo ifakiwe, kunokwenzeka ukuba ezinye iidiski zihluleka ngokukhawuleza. Kwimeko nayiphi na into, kulungele ukuvavanya ukuba i-Raid 0 okanye ezinye ziyafuneka, nangona kubalulekile ukuba nokugcinwa kakuhle kwezi.
Iingqwalaselo zeTekhnoloji yoGcino lweRaid
Kwakusele kubonakala ukuba iteknoloji yeRaid yenye yeengcamango eziphambili xa ujongene nomba wokugcinwa kwedatha ngokukhuselekileyo. Kunye nokusebenza kwayo okungqiniweyo, kuba bubuchwephesha obusetyenziswe iminyaka ethile kwaye buhlala busemthethweni ngenxa yokusebenza kwayo.
Iinkampani ezininzi ezinkulu, ezifana ne-Intel, zibonelela ngezisombululo ze-Raid kunye nokudibanisa kwazo, kwaye kunokwenzeka ukufumana obu buchwepheshe bufumaneka nakwiikhompyutheni zokuhlala, nangona kungabikho rhoqo, ngaphandle kokuba amaqela eengcali eziwaziyo umcimbi.
Ngaloo ndlela, kunokwenzeka ukuba i-Raid isenendlela ende yokuhamba, kwaye kwiminyaka ezayo kufuneka ihlaziye nezinye izinto ezisebenzayo, ukwandisa ukusetyenziswa kwayo kwezinye iintlobo ezahlukeneyo zeemfuno zokugcina kunye nokufikelela kwedatha.
Qiniseka ukuba ujonge la macebiso alandelayo, wakuba ugqibile ukufunda iRaid 0:
