Kulabo basebenzisi abangawazi amagama athile endaweni yobuchwepheshe bekhompyutha, bangase bangazi ukuthi yini yini ukuhlasela 0 kanye nochungechunge lwakhe. Yebo, empeleni ihlotshaniswa nezingxenye zeseva, ezinamadiski e-Raid ngaphakathi. Iqiniso elihlukile elijwayelekile, njengoba ngokuvamile empilweni yasekhaya alisetshenziswa kakhulu, kodwa ezinkampanini ezincane noma eziphakathi nendawo okungenani ithimba elilodwa linayo. Ngaphandle kwayo, abantu abaningi ngenxa yezizathu zokuphepha noma izidingo zobuchwepheshe uma bekhetha ukufaka le divayisi kumakhompyutha abo. Kodwa qhubeka ufunda, ngoba kulokhu okuthunyelwe sizozama ukunikeza imiqondo eyisisekelo kulesi sihloko.
Raid 0, 1, 5, 10, 01, 100, 50: incazelo yazo zonke izinhlobo zayo
Uma ungazi ukuthi iyini i-Raid, cishe awuqondi okuningi uma uzwa ngokucushwa kwediski ku-Riad 0 noma i- I-Raid 0 Windows 10 ezinkampanini ezinkulu. Ngoba kulezi zikhala lapho kudingeka ukusingatha ulwazi ngobuningi, babona isidingo sokuba nedatha ephindaphindiwe netholakalayo. Kodwa-ke, njengamanje cishe wonke amabhodi omama we-PC yedeskithophu anethuba lokudala i-Riad noma eyabo.
Njengamanje kucatshangelwa ukuthi ubuchwepheshe be-Raid 0, ngaphezu kokuba uhlobo olusebenza kahle kakhulu lwe-anti-repellent, buhlobene nobuchwepheshe obusetshenziswa amakhompyutha. Futhi lapha sizobona ukuthi isebenza kanjani kanye nokuba usizo kwayo ekucushweni okuhlukahlukene kwekhompyutha.
Lapha izinhlobo ezahlukene zama-hard drive noma ama-SSD aqala ukugqama ngokukhethekile, njengezindlela ezivumela ukugcinwa kwedatha enkulu ngenxa yamayunithi angaphezu kuka-10 TB angatholakala emakethe namuhla.
Ngalo mqondo ofanayo, igama elisha kubhekiselwa kulo, elifana nokugcinwa kwamafu kanye nezinzuzo elizihlinzekayo kumsebenzisi nethimba ngokwalo, nakuba ngokuqinisekile liqondiswe kakhulu ezinkampanini. Labo abakhokha inkokhelo ukuze babe nalolu hlobo lwenzuzo efinyelelwa ku-inthanethi namaseva akude anezindlela zokuphepha ezithuthukisiwe kanye nezilungiselelo zobunikazi be-Raid 0 ezigcizelela idatha.
Kuyafaneleka futhi ukusho ukuthi ubuchwepheshe be-Raid busetshenziswa kakhulu ekuguquleni idatha ebalulekile, lapho kungenakwenzeka noma kufiswa ukunikeza idatha eyodwa ngenxa yezizathu ezihlukahlukene, njengezinkinga ezingaba khona zemvelaphi yomshini noma kagesi ezingase zenzeke. kumadiski okugcina.
Kuyaziwa futhi ukuthi ezinhlanganweni noma ochwepheshe, ukulahlekelwa ulwazi kungaholela emonakalweni omkhulu. Lapho ubuchwepheshe be-Raid, buhlanganiswe ngokufanele futhi busetshenziswe iminyaka ethile, buyindlela ephumelela kakhulu yokuvikela ulwazi futhi, esimweni sezinkampani, buyisiqinisekiso sebhizinisi. Kodwa ngaphambi kokuqhubeka, kulula ukwazi imiqondo ethile ehlobene nalobu buchwepheshe.
Buyini ubuchwepheshe be-Raid?
Igama elithi RAID lisuka ekuqanjweni kwesiNgisi Uhlu Olungafuneki Lwamadiski Azimele, futhi lisho ukuthini uhlu olungadingekile lwamadiski azimele. Njengoba igama layo liphakamisa, isivele inikeza umbono wokuthi lobu buchwepheshe bufunani, njengoba kunjalo ngokwakha uhlelo lokugcina idatha kusetshenziswa amayunithi okugcina ahlukahlukene ukuze kusatshalaliswe idatha noma ukuphindaphinda. Amayunithi anjalo okugcina angaba ama-HDD hard drive noma i-SSD noma amasistimu wesimo esiqinile.
Ubuchwepheshe be-Raid 0 buhlukaniswe ngokucushwa okubizwa ngokuthi amaleveli, okungatholwa ngakho imiphumela eminingi ngokufinyelela kokugcinwa kwedatha. Ngenxa yezizathu zokusebenziseka, kulokhu okuthunyelwe sizobona i-Raid njengesitolo sedatha esisodwa, esifana neyunithi eyodwa enengqondo, naphezu kweqiniso lokuthi kukhona ama-hard drive amaningana azimele ngaphakathi kuwo.
Kuyafaneleka futhi ukusho ukuthi inhloso yeRaid kanye nochungechunge lwayo oluhlukahlukene ukunikeza umsebenzisi umthamo omkhulu wokugcina, inala yedatha ukuze ingalahleki, futhi inikeze isivinini esikhulu ekufundeni nasekubhaleni, njengokungathi kukhona kuphela. idiski eyodwa. Izici ezinjalo zithuthukiswa ngokuzimele ngokuya ngeleveli ye-Raid ezosetshenziswa.
Enye inzuzo yokusebenzisa i-Raid yiqiniso lokuthi ungasebenzisa ama-hard drive amadala nokuthi angaxhunywa ngesibonisi se-SATA ebhodini lomama. Ngale ndlela, ngamayunithi angabizi kakhulu, ingafakwa ezindleleni zokugcina lapho idatha izovikelwa ekuhlulekeni.
Kusetshenziswa kuphi iRaid 0 nezinye?
Ukugasela nochungechunge lwabo sekusetshenziswe isikhathi eside ezingeni lezinkampani, ngenxa yevolumu nokubaluleka kolwazi abaluphethe kanye nesidingo sokulugcina luphephile. Lezi zineseva okungenani eyodwa ekhethekile yokuphatha lesi sitolo sedatha, enezingxenyekazi zekhompuyutha eziklanyelwe lolu hlobo lwesevisi yokuvikela ezinsongweni ezingaba khona zangaphandle kanye nokuvimbela ukufinyelela okungenzeka kuzo.
Ngokuvamile, lezi zindawo zokugcina zisebenzisa ama-hard drive ngokusebenza okuqondile kanye nobuchwepheshe bokukhiqiza, ukuze isikali sazo siphezulu futhi silungile. Nakuba okwamanje, abasebenzisi abaningi bangasebenzisa uhlelo lwe-Raid uma benebhodi lomama elisha kanye ne-chipset ukuze bafake lolu hlobo lwemiyalo yangaphakathi.
Ngalokhu, okuwukuphela kwemfuneko iwukuba namadiski amaningana axhunywe kwiphakheji yesisekelo ukuze kuqalwe ukucushwa kwe-Linux, Mac noma i-Windows Raid 0. Uma ungenayo imishini, akulula ukusebenzisa lolu hlobo lobuchwepheshe, njengoba isilawuli se-Raid sidingeka ukuphatha isitolo ngokuqondile kusuka ku-hardware, naphezu kokuthi uhlelo lusengozini yokwehluleka kwalesi silawuli, into eyenzayo. akuvamile ukwenzeka uma iphethwe nge-software.
Ngidingani ukwenza i-Raid 0 noma enye?
Ukuhlasela kuvame ukufakwa kumaseva noma i-NAS, nakuba kungenziwa kumakhompyutha avamile. Nakuba kuvamile ukukwenza kumakhompiyutha alula njengoba ukuphathwa kwayo kudinga ukwazi ulwazi oluyisisekelo, futhi futhi, kunezindleko noma ubungozi okungeyena wonke umuntu ozimisele ukukuthatha, ngoba akusinxephezeli. Manje, unethuba lokuyimisa ngesoftware, ihadiwe noma okuxubile.
Ku-software Raid 0, isistimu yokusebenza ngokwayo enesibopho sokuphatha amavolumu. Lokhu kusho ukuthi i-CPU kufanele yabe izinsiza zokuphatha i-Raid futhi, ngendlela yokuthi ikhompuyutha ihambe kancane. Cishe bonke abakhiqizi be-NAS (I-Synology, QNAP, noma abanye) sebenzisa lokhu i-softraid kumakhompiyutha abo, bakwazi ukubona lapho inqwaba yedatha ilahlwa, kanye nama-CPU anomthwalo omkhulu wokusebenza ngenxa yalesi sizathu.
Kuyafaneleka futhi ukusho ukuthi ngamaphrosesa amanje anama-cores angu-2 noma ngaphezulu, lo mthwalo awuthinteki kangako, naphezu kokuba usaphawuleka.
Ngenkathi i-Hardware Raid 0 idinga ukuthi umsebenzisi afake ikhadi lesilawuli se-Raid, futhi ahlanganise i-CPU nememori yayo. Lokhu kuzuza ukuzinikela okuphelele ngomlawuli oshiwo wenqubo yokuphatha yesistimu ye-Raid, kanye nokukhululwa kwale nqubo ku-CPU emaphakathi.
Ngale ndlela, kuwuhlelo olusetshenziswa ikakhulukazi phakathi nebanga ukuya kumaseva aphezulu, olunikeza ukuzethemba, ukuphepha kanye nesivinini esidingekayo kulolu hlobo lwedivayisi.
Ngokuqondene neHybrid noma i-Raid exubile, ithobela i-RAID-mbumbulu evame ukulawulwa kusukela ku-BIOS yamabhodi omama athile ukuze ifane ne-Hardware Raid kodwa enezici ezinomkhawulo. Ukuze usebenzise lesi simiso, kuyadingeka ukuqinisekisa ukuthi ipuleti iyayihlanganisa, ngoba akubona bonke abanayo.
Uhlelo olushiwo ngeke luthathe izinsiza ku-CPU noma inkumbulo, njengoba uhlelo lokusebenza lungaluphathi, nakuba ukusebenza kwesilawuli sehadiwe kungeke kutholwe noma, ngokusobala, ukuthembeka kwaso. Ngisho lena indlela evame ukwethula ukwehluleka okwengeziwe.
Ukufingqa-ke, kungashiwo ukuthi i-Hardware Raid iyona engcono kunazo zonke kuzo zonke izakhi zobuchwepheshe, futhi ibiza kakhulu. Ilandelwa yi-hybrid, edinga i-motherboard yokusekela, kufanele iye kukhwalithi ephakathi / ephezulu ukuze ihlanganiswe, nakuba ingakhanselwa ngokuthembeka. Ekugcineni, i I-SoftRAID Kuzoba mahhala, uma uhlelo lokusebenza luvumela, kodwa ngezindleko mayelana nezinsiza ngezindleko zesistimu yokufanisa.
Yini engakwazi futhi engakwazi ukwenza i-Raid 0 noma ezinye?
Ukucaca mayelana nokuthi iyini i-Raid kanye negalelo layo nokusetshenziswa okungaba khona, kuyadingeka ukwazi izinzuzo zayo kanye neminikelo kumsebenzisi ngokusebenzisa kwayo uhlelo, kanye nemikhawulo yayo. Ngale ndlela, kugwenywa ukuwela ephutheni lezinsiza zokucabanga kuyilapho zingenayo ngempela. Ake sibone izinzuzo zayo nokuthi yini ongayilindela ku-Raid 0:
Izinzuzo ze-Raid 0
Ukubekezelela amaphutha okuphezulu: I-Raid 0 ivumela ukubekezelelana okungcono kwamaphutha kunokuba une-hard drive eyodwa kuphela. Le nzuzo izoba ngaphansi kwezilungiselelo zalesi sici kanye nohlobo olwamukelwayo, ngoba eziningi zihloselwe ukuhlinzeka ngokuphindaphinda, kanti ezinye zihlinzeka ngesivinini sokufinyelela kuphela.
Ukusebenza okungcono kokufunda nokubhala: Njengasesimeni sangaphambilini, kunezinhlelo ezigxile ekwandiseni ukusebenza kahle, ngokuhlukaniswa kwamabhulokhi wedatha abe amayunithi ahlukahlukene, ukuze asebenze ngokuhambisana.
Amathuba okuhlanganisa zombili izakhiwo zangaphambilini: Sesiyazi kakade ukuthi amadigri e-Raid angahlanganiswa, lokhu kukhethekile kuvumela umsebenzisi isivinini sokufinyelela esikhulu kwabanye kanye nokungafuneki kwedatha komunye.
I-scalability enhle nomthamo wokugcina: enye inzuzo yiqiniso lokuthi zingamasistimu angaka kalula, kuye ngokucushwa onakho. Ngesikhathi sokusebenzisa amadiski omthombo ohlukahlukene kanye nemvelo, izakhiwo, umthamo kanye neminyaka.
Yini i-Raid 0 noma abanye abangakwazi ukuyenza?
Njenganoma iyiphi enye indlela yekhompiyutha, i-Raid 0 inemikhawulo yayo, enye yazo ukuthi akuyona isiteshi sokuvikela idatha, ichaza ulwazi, kodwa ayilivikeli, kokubili imibono ihlukile. Lapho igciwane lingenza umonakalo ofanayo ku-autonomous hard drive, njengokungathi iRaid ingene. Ngakho-ke, uma ungenalo uhlelo lokuvikela, ulwazi luzodalulwa ngokulinganayo.
Ngokufanayo, isivinini esiphezulu asiqinisekisiwe futhi, kukhona ukulungiselelwa umsebenzisi angakwenza, nakuba kungezona zonke izinhlelo zokusebenza noma imidlalo engasebenza kahle ku-Raid. Ngokuvamile, ngeke kube nenzuzo yokusebenzisa ama-hard drive angu-2 esikhundleni sika-1 ukuze ubambe idatha ngendlela yokuhlukanisa.
Ububi be-Raid 0
Futhi, i-Raid ayiqinisekisi ukutholakala kwenhlekelele, futhi njengoba kwaziwa, kunezinhlelo zokusebenza ezikwazi ukubuyisela amafayela ku-hard drive esimweni esibi. Kodwa i-Raid idinga abashayeli abahlukene nabathize, futhi abahambisani nezinhlelo ezinjalo. Ngakho-ke, uma kwenzeka ukuhluleka kweketango noma amadiski amaningana, kungase kube idatha engatholakali.
Ngakolunye uhlangothi, ukufuduka kolwazi kuyinkimbinkimbi, kuyilapho ukuhlanganisa i-disk ngesistimu yokusebenza kulula, nge-Raid ephelele kwenye, kuwumsebenzi onzima uma ungenayo amathuluzi abonisiwe. Okusho ukuthi, ukuthutha amafayela kusuka kusistimu eyodwa kuya kwenye ukuze kuthuthukiswe kungaba okungenakunqotshwa.
Okokugcina, kunezindleko zokuqala, nakuba ukusebenzisa i-Raid enama-disks angu-2 kulula, uma ufuna ukwenza amasethi ayinkimbinkimbi namazwi, izinto ziba nzima. Okungukuthi, uma kukhona ama-disks amaningi, izindleko ziphakeme, futhi uma uhlelo luyinkimbinkimbi, kuzodingeka eziningi zazo.
Imaphi amazinga e-Raid akhona?
Njengamanje, kuyenzeka ukuthola izinhlobo ezahlukene zeRaid emakethe, nakuba lezi zihlukaniswe ngamaleveli ajwayelekile, akhiwe esidlekeni nalawo aphathelene nokuphathelene. Lapho okuvame kakhulu khona yilezo ezisetshenziswa abasebenzisi abazimele kanye nezinkampani ezincane, yizona ezijwayelekile nezinezidleke, njengoba ingxenye enhle yemishini ephezulu ingakwenza ngaphandle kokufaka okunye.
Ngokuphambene, amazinga obunikazi asetshenziswa kuphela abadali ngokwabo noma yilabo abanikeza lolu hlobo lwesevisi. Manje, ezingeni lokumisa, izinhlobo ezihlukahlukene zingasethwa kuye ngokuthi inhloso. Ukwazi ukuzenza zibe lula, uma ufuna ukukhulisa ukusebenza, okukhethwa kukho i-Raid 0, kuyilapho ukunikeza ukuphepha kwedatha okukhulu, okuhle ukukhweza i-Raid 1.
Futhi kusukela esidingweni sokuba nazo zombili lezi zindlela, yonke enye i-Raid yavela, njengochungechunge 5, 6, 10 nokuhluka kwayo. Ngokuya ngenani lamadiski onawo, ungasebenzisa eyodwa noma enye. Lapho uchungechunge 0 no-1 lufinyeleleka kakhulu, njengoba kuphela amadiski angu-2 adingekayo (okungenani, ngoba angaba ngaphezulu) futhi njengezikali zedatha, layisha kwenye, kuze kufinyelele imfuneko yediski ephakeme. Kodwa ake sibheke ngayinye yalezi zisetshenziswa:
Ukugasela 0
Njengowokuqala we-Raid, okubizwa ngokuthi ileveli 0 noma isethi ehlukanisiwe yazalwa. Kulokhu akukho ukuphindaphindeka kwedatha, njengoba umsebenzi waleli zinga uwukusabalalisa idatha egcinwe phakathi kwama-hard drive ahlukene axhunywe kwikhompyutha. Inhloso yayo ukuhlinzeka ngesivinini sokufinyelela olwazini olugcinwe kuma-disks, njengoba ulwazi lusatshalaliswa ngokulinganayo kubo ukuze lunikeze ukufinyelela ngesikhathi esisodwa, kanye nomthamo omkhulu wedatha namayunithi ayo ngokufana.
I-raid 0 ayiqukethe ngisho noma idatha yokukhuluma, ngakho-ke, uma enye yamayunithi okuqukatha iphuka, yonke idatha engaphakathi kuyo izolahleka, ngaphandle uma kukhona amakhophi ayisipele angaphandle okulungiselelwa okushiwo.
Uma ufuna ukwenza i-RAID 0, kufanele ubheke usayizi wama-hard drive awenza. Isho i-hard drive encane eshayela isikhala esengeziwe ku-RAID. Futhi uma unedrayivu engu-1TB kanye nedrayivu engu-500GB ekucushweni, usayizi wesethi yokusebenza uzoba ngu-1TB, kuthatha idrayivu engu-500GB kanye nenye engu-500GB yedrayivu ye-1TB. Ngakho-ke, kulula ukwamukela amadiski osayizi ofanayo ukuze usebenzise ngokunenzuzo yonke indawo etholakalayo kusethi eklanyelwe.
Ukugasela 1
Ngokwengxenye yayo, ukucushwa kwe-Raid 1, okubizwa ngokuthi i-mirroring, kungenye yezinto ezivamile ezisetshenziselwa ukunikeza ukuphindaphinda kwedatha nokubekezelelana kwamaphutha. Uma kunjalo, okwenziwayo ukukhiqiza isitolo esinedatha eyimpinda kuma-hard drive angu-2, noma amasethi angu-2 alawa. Lapho ulondoloza ucezu lwedatha, luphindaphindwa ngokushesha kuyunithi yesibuko, bese kuba nokuqukethwe okungu-2 kwedatha efanayo.
Ngokubuka uhlelo lokusebenza, uneyunithi eyodwa yokugcina, lapho ungaya khona ukuze ufinyelele idatha ekulo. Nokho, uma kwenzeka ukwehluleka, idatha kudrayivu ephindiwe izokhunjulwa ngokuzenzakalelayo. Kusebenza futhi ekuthuthukiseni isivinini sokufunda, njengoba ulwazi lungafundwa ngesikhathi esisodwa kuwo womabili amayunithi anezibuko.
Ukugasela 2
Izinga lesi-2 le-Raid alisetshenziswa njalo, njengoba lisekelwe ekulondolozeni okuhlelwe kahle kumadiski amaningana ezingeni elincane. Futhi ngesikhathi esifanayo, ikhiqiza ikhodi yephutha yokusabalalisa idatha eshiwo futhi igcinwa kumayunithi akhethekile ngale njongo. Ngale ndlela wonke amadiski esitolo ayakwazi ukugadwa futhi avumelaniswe ukuze kufundwe nokubhala idatha.
Njengoba okwamanje ama-disks eza nesistimu yokuthola iphutha, lokhu kulungiselelwa akufanelekile, futhi kusetshenziswa uhlelo lokulinganisa kuphela.
Ukugasela 3
I-Raid 3 ayisetshenziswa okwamanje, futhi ihilela ukuhlukaniswa kwedatha ezingeni le-byte ibe amayunithi ahlukahlukene akha i-Raid, ngaphandle kweyodwa lapho kulondolozwa khona ulwazi lokulinganisa oluvumela ukuthi le datha ihlanganiswe uma ifundwa. Ngakho, ibhayithi ngayinye egciniwe inebhithi yokulinganisa engu-1 eyengeziwe evumela amaphutha ukuthi akhonjwe futhi idatha iphinde itholwe uma kwenzeka ukulahleka kweyunithi.
Inenzuzo yokuthi idatha ihlukaniswe ngamadiski amaningana futhi ivumela ukufinyelela okusheshayo kolwazi, inqobo nje uma kukhona amadiski afanayo kuwo. Ukucushwa kwayo kudinga okungenani ama-hard drive angu-3.
Ukugasela 4
Iphinde futhi ithobele indawo yokugcina idatha ehlukaniswe ngamabhulokhi phakathi kwamadiski, kodwa ishiya enye yalezi ukuze kugcinwe amabhithi okulingana. Umehluko wayo ofaneleka kakhulu ngokuhlobene ne-Raid 3 useqinisweni lokuthi uma iyunithi ilahleka, idatha ingakhiwa kabusha ngesikhathi sangempela ngenxa yamabhithi okulingana okubaliwe.
Ngokuyisisekelo kuthambekele ekugcinweni kwamafayela amakhulu, ngaphandle kokuphinda asetshenziswe, nakuba ukuqoshwa kwedatha kuhamba kancane ngenxa yesidingo sokwenza lesi sibalo sokulinganisa isikhathi ngasinye lapho okuthile kurekhodwa.
Ukugasela 5
I-Raid 5 ibizwa nangokuthi uhlelo olusabalalisiwe olunokulingana; namuhla isetshenziswa kaningi kunamazinga 2, 3 kanye no-4, ikakhulukazi kumishini ye-NAS. Ulwazi lugcinwa luhlukaniswe ngamabhulokhi asakazwa phakathi kwama-hard drive akha i-Raid; kanye nokukhiqiza ibhulokhi yokulingana ukuze kuqinisekiswe ukuphinda kusetshenziswe kabusha, kanye nokwakha kabusha ulwazi uma kwenzeka i-hard disk yonakala.
Isitsha esishiwo sababili sizogcinwa kuyunithi ngaphandle kwedatha ehilelekile kuyo ebaliwe, ngalokhu imininingwane yokulinganisa izogcinwa kudiski ehlukile, lapho kukhona amabhulokhi wolwazi oluhlobene.
Ngokufanayo, kudingeka okungenani amayunithi wokugcina angu-3, ukuze kuqinisekiswe ukuphinda kusetshenziswe ngokulingana, futhi kuzobekezelela kuphela ukwehluleka kweyunithi eyodwa ngesikhathi. Uma oku-2 kwalokhu kuphulwa ngesikhathi esisodwa, ulwazi lokulingana luzolahleka, futhi okungenani ibhulokhi eyodwa yedatha ehilelekile. Kukhona futhi okuhlukile kwe-Raid 5E, eklanyelwe ukubeka i-hard drive eyisipele futhi inciphise isikhathi sokwakha kabusha, uma kwenzeka ukwehluleka kokukodwa kokuyinhloko.
Ukugasela 6
I-Raid 6 ngokuyisisekelo isandiso sika-5, lapho elinye ibhulokhi lamapheya lenezelwa inani elingu-2. Lapho amabhulokhi olwazi azosatshalaliswa ngamayunithi ahlukene, futhi, kuyingxenye yamabhulokhi agcinwe kumayunithi angu-2 ahlukene. Ngalokhu, uhlelo luzobekezelela ukwehluleka kwamayunithi wokugcina we-2, ngakho-ke, kuze kufike kumayunithi angu-4 adingekayo ukuze enze i-Raid 6E; okuphinde kudale ukwehluka kwayo kwe-6E ngenjongo efanayo neka-5E.
Ukugasela 10
I-Raid 10 iqanjwe njengenyunyana ye-Raid 0 kanye no-1, emise ivolumu eyodwa; okufezwa ngayo uhlelo olunokusebenza okuphezulu nokungadingeki. Kulesi simo, ukucushwa kwayo kudinga okungenani amadiski angu-4, angacatshangwa njenge-Raid 6, kodwa ngokusebenza okwengeziwe.
Lo mbono awulona iqiniso ngokuphelele, ngoba ngokuqinisekile, ufuna ukuthuthukisa ukubhala nokufunda ku-Raid 5 noma 6, nakuba idiski eyodwa kuphela engahluleka. Lokhu kungenxa yokuthi amadiski angu-2 aqukethe idatha ye-A1 kanye no-2 ulwazi lwe-A2. Futhi uma kwenzeka ukwehluleka kwediski ene-A1 nenye ene-A2, kuzokwazi ukuqhubeka nokusebenza njengoba kunamadiski angu-2 ane-A1 ne-A2 esele. Futhi uma womabili amadiski ane-A1 noma i-A2 ehluleka, ivolumu ngeke ifinyeleleke njengoba uhhafu wedatha yawo ulahlekile.
Amazinga Wokuhlasela Okusidleke
Ngemva kokubona amazinga ayisisekelo e-Raid kanye nokusetshenziswa kwawo, sizoxoxa kafushane ngamaleveli afakwe esidlekeni; Ngokunokwenzeka, amaleveli anjalo ngokuyisisekelo abhekisela kumasistimu aneleveli eyinhloko ye-RAID, kodwa ngesikhathi esifanayo aqukethe amanye amaleveli angaphansi ahlinzeka ngokusebenza kokucushwa okuhlukile.
Ngale ndlela, izingqimba ezihlukahlukene ze-Raid ziyafakazelwa, zonke zikwazi ukwenza ngesikhathi esisodwa imisebenzi ethile evamile yamazinga ayisisekelo, futhi ngalokhu, ukuhlanganisa amandla okufunda ukufinyelela ngokushesha nge-Raid 0 kanye nokuphindaphinda. , ukuze sikuqonde kangcono, ake sibone okuvame kakhulu okwamanje:
ukuhlasela 0 + 1
Lokhu Raid kungatholakala emakethe njenge-Raid 01 noma isibuko sezigaba; futhi ngokuyisisekelo ibhekisela ezingeni eliyinhloko lohlobo lwe-Raid 1, nemisebenzi yokuphindaphinda idatha etholakala kuleveli encane yokuqala neyesibili. Ngesikhathi esifanayo, kuzoba ne-Raid 0 sublevel enemisebenzi efanayo ehambisana nayo, okungukuthi, ukulondoloza idatha esatshalaliswa phakathi kwamayunithi atholakalayo kuyo.
Ngakho-ke, izinga eliphakathi litholwa ngomsebenzi wesibuko ofanayo kanye nama-sublevels anomsebenzi wokuhlukanisa ulwazi. Ngalokhu, uma i-hard drive yehluleka, idatha izohlala ingashintshiwe futhi ivikelwe kwesinye isibuko se-Raid 0.
Lolu hlelo lubika njengobubi obuyinhloko, ukukala kwalo, lapho wengeza idiski eyengeziwe ezingeni eliphansi, kuzodingeka futhi wenze okufanayo kwenye. Ukwengeza, ukubekezelela amaphutha kuzovumela ukugqashuka kwediski ehlukile kuleveli encane ngayinye, noma 2 kuleveli engaphansi efanayo, kodwa hhayi ezinye izinhlanganisela, ngoba idatha izolahleka.
ukuhlasela 1 + 0
Njengoba kuphawuliwe esihlokweni sayo, kuyisimo esiphambene, esivame ukubizwa ngokuthi i-Raid 10 noma ukuhlukaniswa kwesibuko; okuzoba khona izinga elimaphakathi lohlobo lwe-Raid 0, futhi ehlukanisa idatha egciniwe phakathi kwamaleveli angaphansi ahlukahlukene. Futhi ngasikhathi sinye, kuzoba nama-sublevels ohlobo lwe-1 ahlukahlukene, anesibopho sokuphindaphinda idatha kuma-hard drive angaphakathi.
Uma ukubekezelelana kwamaphutha kunikezwa, lokhu kuzovumela ukuphulwa kwawo wonke amadiski wezinga eliphansi, ngaphandle kweyodwa yazo, okudingekayo ukuthi okungenani idiski eyodwa igcinwe inempilo enhle kuzinga ngalinye elingaphansi, ngenhloso yokungalahlekelwa ulwazi olugcinwe lapho .
Ukugasela 50
Kungenzeka ukwenza izinhlanganisela eziningi kusukela ku-Raid 0, kuze kube yilapho uthola ukuphindaphindeka okuphakeme, ukwethembeka okukhulu nesivinini. Kulokhu, nge-Raid 50, ethobela izinga elimaphakathi ku-Raid 0 eklanyelwe ukuhlukanisa idatha yamazinga aphansi alungiselelwe njengezinga lesi-5, nama-hard drive awo angu-3.
Ukwenza lokhu, ibhulokhi ngayinye ye-Raid 5 inikeza isethi yedatha ngokulingana kwayo. Kulokhu, i-hard drive ingahluleka kuyo yonke i-Raid 5, futhi nokho izoqinisekisa ubuqotho bedatha, kuyilapho uma ihluleka kakhulu, idatha egcinwe ngaphakathi kuyo izolahleka.
ukuhlasela okungu-100 no-101
Kumele kuqashelwe kuleli cala ukuthi awukwazi nje ukuba nesihlahla esinezinga le-2, kodwa 3, kunjalo icala lesiphakamiso se-Raid 100 noma i-1+0+0. Lokhu kuqukethe amaleveli angaphansi angu-2 e-Raid 1+0 ehlukaniswa ngokushintshana ngeleveli emaphakathi ku-Raid 0. Ngokufanayo, i-Raid 1+0+1 ingahlanganiswa, yenziwe ngamaleveli aphansi ahlukene ka-1+0 aboniswa i-Raid 1 njengento eyisisekelo. .
Kulokhu, isivinini sokufinyelela kwayo kanye nokuphindaphinda kuzofinyelela emazingeni amahle kakhulu, abika ukubekezelelana okuhle ukubhekana nokuhluleka okungenzeka, nakuba inani lama-disks okufanele lisetshenziswe likhulu uma liqhathaniswa nendawo etholakalayo.
Khetha I-Raid
Manje, ngemva kokubona izinhlobo ezihlukene namazinga e-Raid, kusukela ku-Raid 0 yokuqala, inselele isele ukunquma ukuthi ungayikhetha kanjani enye yalezi. Yebo, sekuvele kubonisiwe ukuthi izinkulungwane zezinhlanganisela zingenziwa, okwenza isinqumo sokukhetha uhlelo oluhle noma olufanele lube nzima kakhulu. Uma unamadiski amaningi, ungakhetha ukwenza iRaid 1+0, 0+1, 50, 60 ngezinhlobonhlobo zayo eziningi.
Ngale ndlela, ukuze kube lula ukukhetha, izibali ze-Raid ziyatholakala kuwebhu, ezisiza ngezibalo ezidingekayo. Futhi, kuyathakazelisa ukwazi ukuthi kukhona abalawuli abavumela umsebenzisi ukuthi alungiselele idiski spare. Okuyinto engaphezu kokuxhuma idiski ngaphandle kokuyisebenzisa nokuyiqala uma kwenzeka ukwehluleka kwenye idiski.
Kube sekuyinqubo yokwakha kabusha i-Raid 0 esisingathwa yisilawuli ngokuzenzakalelayo, uma kwenzeka kutholwa idiski eyonakele. Phakathi kwemisebenzi ebaluleke kakhulu uma i-Raid isifakiwe wukugada ngendlela eqinile isimo samadiski; njengoba ukuba nokuphindaphindeka akusho ukuthi isimo sedatha egcinwe ngaphakathi kuyona sizoshaywa indiva.
Lokhu kungenxa yokuthi wonke amadiski angonakaliswa, okudinga ukubuyekezwa ukuze kutholwe izinkinga ezingaba khona. Lokhu kubalulekile futhi uma i-disk ihluleka futhi kufanele ishintshwe ngokushesha ngangokunokwenzeka, njengoba inomjikelezo wokuphila owusizo, futhi uma imodeli efanayo ifakiwe, kungenzeka ukuthi amanye ama-disks ahluleka maduzane. Kunoma yikuphi, kulula ukuhlola ukuthi i-Raid 0 noma ezinye iyadingeka yini, nakuba kubalulekile ukuba nokugcinwa kahle kwalokhu.
Raid Storage Technology Ukucatshangelwa
Sekuvele kwacaca ukuthi ubuchwepheshe be-Raid bungomunye wemiqondo eyinhloko lapho kubhekwana nendaba yokugcinwa kwedatha ngendlela evikelekile. Kanye nempumelelo yayo efakazelwe, njengoba iwubuchwepheshe obusetshenziswe iminyaka ethile futhi obugcina ubuqiniso bayo ngenxa yokusebenza kahle kwayo.
Kunezinkampani eziningi ezinkulu, njenge-Intel, ezinikeza izixazululo ze-Raid noma izinhlanganisela zazo, futhi lobu buchwepheshe bungatholakala ngisho nakumakhompiyutha okuhlala, nakuba akuvamile kakhulu, ngaphandle kwamaqembu ochwepheshe abalwaziyo lolu daba.
Ngale ndlela, kungenzeka ukuthi i-Raid isenendlela ende okufanele ihambe, futhi eminyakeni ezayo kufanele isungule nezinye izinto zokusebenza, yandise ukusetshenziswa kwayo kwezinye izinhlobo ezihlukahlukene zezidingo zokulondoloza kanye nokufinyelela kwedatha.
Qiniseka ukuthi ubheka iziphakamiso ezilandelayo, uma usuqedile ukufunda i-Raid 0:
- Uhlelo lokususa amafayela
- izici zehadiwe
- izingxenye zeprosesa
