Xa kuziwa kugcino lwedatha, iinkqubo ze-RAID ziyinto yokuqala eza engqondweni yomntu. Ngeenkqubo ze-RAID, sinokuba nakho ukukhuselwa kwedatha, kunye nokusebenza ngokukuko. Ezi nkqubo zinokusinceda ngokufanayo ukufumana iingxaki zenkqubo eqhelekileyo. Nangona kunjalo, yonke inkqubo ine-loophole yayo.
Njengabanye, i-RAID inayo eyayo nayo. Ngamanye amaxesha, eminye imiba kunye neseva yeRAID inzima kangangokuba awukwazi ukuyijonga nje. Iingxaki ezinokuthi zenzeke nge-RAID iseva zinokubandakanya ukusilela kwiidrive ezininzi, okanye isilawuli ngokunjalo. Iseva yakho yeRAID inokufumana ilahleko yokumisela ngamanye amaxesha.
Kwaye, ukutyibilika kwabantu okuqhelekileyo yenye ingxaki enokwenzeka eyenzeka kubantu abaninzi. Nangona kunjalo, kuya kufuneka uxinzelelo malunga nezi ngxaki. Kukho unyango kuzo zonke izifo ehlabathini. Kuya kufuneka uhlale uyigcina engqondweni.
Ukufumana kwakhona idatha ye-RAID kunokwenzeka, kwaye zininzi iindlela onokufikelela kuzo. Iqinisekisiwe Iinkonzo zokubuyisa idatha yeRAID inokuza iluncedo kuwe ngala maxesha ukuba uqhekeze iingqondo zabo kwiingxaki zakho. Oku kuchacha kwakhona kunokuba nesoftware yeprimiyamu. Kodwa, ukufumana kwakhona idatha ye-DIY, kuya kufuneka ube nakho ukwazi amantongomane kunye neebholithi zecebo ozama ukulifumana kwakhona kuba kukho amaxesha apho abantu bazama ukubuyisa idatha yabo kwaye baphele bephulukana nedatha yabo egciniweyo endaweni yoko.
Iinkqubo ezininzi zokubuyisa idatha ziyafumaneka kwintengiso kule mihla. Iinkqubo ze-RAID zifuna izixhobo eziyilelwe ukuba zisetyenziswe kwiiseva zokuhlasela. Izixhobo zokubuyisa idatha ze-RAID ziza noluhlu lweentlobo, kodwa eyona njongo iphambili yezi zixhobo ihlala injalo- ukubuyisela iifayile ezilahlekileyo okanye ezisuswe ngempazamo.
Kuya kufuneka ujonge ezona mveliso zithengiswayo. Ezinye iimveliso zinokwenza ukuba inkqubo yenze yodwa; basebenza ngendlela ezenzekelayo. Izixhobo zinokukhangela inkqubo yohlaselo ngaphambi kokuba zisebenze kwakhona.
Inye into ekufuneka uyigcinile engqondweni ukuba ixabiso lezixhobo eziyilelwe ukubuyisa iinkqubo zohlaselo zinokubiza ngaphezulu kunezixhobo zokubuyisa idatha. Ke, ngaphambi kokukhetha isixhobo kwiseva yakho yohlaselo, qiniseka ukuba iza nokuthembeka okuphezulu kunye nenqanaba lempumelelo. Sukugqibela ngokufumana isixhobo esinokuthi singasetyenziselwa wena. Soloko unquma ukuthenga eyona ilungele ukuseta kwakho. Kungoko kuphela apho unokuphumelela ngokufumana kwakhona kwakhona kwedatha yakho ye-DIY.
Kutheni iRAID iphumelela kwezorhwebo?
Iinkqubo ze-RAID zixhaphakile kwihlabathi liphela njengoko umntu enokufumana iindlela ezininzi zokubuyisela kwimarike efumanekayo ukuze ayenze. Ngaphandle koko, ezi nkqubo ziza nomthamo wokugcina ongcono. Baninzi ababoneleli beenkonzo zokubuyisa idatha abajolise ekubuyisweni kwedatha yeRAID. Banokufumana idatha elahlekileyo ngokufanelekileyo xa kuthelekiswa noogxa babo.
Ezinye izibonelelo zokusebenzisa i-RAID zingabandakanya:
- Ngeediski ezinzima ze-RAID, unokukwazi ukufumana ukuphazamiseka kwenkqubo. Ezi diski ezinzima zezona zilungileyo xa kufikwa ekuncedeni umntu wokuzilungisa ukuba alungise kakhulu.
- Ezi diski zinzima ngokuqhubekayo zibhala kwaye zibhale idatha. Njengoko iyinkqubo eqhubekayo, iphucula isantya kwezi diski.
- Ngeenkqubo ze-RAID, unokulungiselela ukugcinwa kwedatha, okukhuthaza inkqubo yokusebenza ukuba isebenze ngokufanelekileyo ngaphandle kokuphazamiseka.
- Kukho amathuba okulahleka kwedatha ngedatha yeRAID. Ngenxa yoko, awuyithwalisi ingxaki yokufumana kwakhona idatha rhoqo.
Amanqanaba ahlukeneyo e-RAID
I-RAID 0-Ukubamba
I-RAID 0 luluhlu olunemigca yediski engafikanga nanyamezelo. Oku kuthetha ukuba ukuba enye yeedrive ilahlekelwa yidatha, lonke uluhlu lwedatha lulahlekile.
I-RAID 1-Ibukusa
Eli nqanaba lokuhlasela libonelela ngesibuko sediski. Eli nqanaba libonelela ngokuphindwe kabini kwinqanaba lokuthengiselana kwidiski enye xa kuthelekiswa nokubhalwa kokubhalwa kwento enye yediski enye.
I-RAID 5-Ukubhabha ngeParity
Kwi-RAID 5, ukubekwa kwedatha kwenzeka kwinqanaba le-Byte, ngelixa impazamo yomtya sisizathu sokulungiswa kolwazi. I-RAID 5 inokulungela ukusebenza kwe-notch ephezulu kunye nokunyamezelana okungalunganga. Akukho mntu ufuna ukuphulukana nedatha yakhe. Ukuqinisekisa ukhuseleko lwedatha, umntu kufuneka ayazi ukuba uyigcina njani idatha usebenzisa i-RAID drive.
I-RAID 6-Ukubhabha ngeParity Parity
Inqanaba lesithandathu elinokulingana kabini liza neediski ezizimeleyo zedatha ezikhoyo. Eli nqanaba lokuhlasela lifuna iidiski ezine. Kwimigca emine, isebenzisa imivumbo emibini yokulingana. Le diski iza nenqanaba eliphezulu lokunyamezelana kweziphoso njengoko iza nobabini. Ixabiso lale disk linokuphakama ngenxa yokuphinda kabini ukusebenza kwayo.
I-RAID 10 -Ukudibanisa isibuko kunye nokuHamba
Inqanaba lokugqibela le-RAID hard drive yaziwa ngokuba yi-RAID 1 + 0 okanye i-RAID 10. Eli nqanaba liboniswa ngokubandakanya isibuko se-RAID 1 ngaphezulu kwemivimbo emibini ye-RAID 0. Ukuba ufuna ukukopa idatha kwaye usasaze phakathi kwezinye iidiski, i-RAID 10 inokuba yeyona ilungileyo kuwe.
Ngaphezu kwakho
Ukufumana idatha kwiserver RAID ngesoftware yokufumana idatha kunokwenzeka. Kodwa, kungcono ukuba ube nengcali yokufumana kwakhona idatha ukuze unakekele imeko yonke. Icala elisezantsi kuphela lokuba nenkampani yokubuyisela idatha eqeshwe kwiseva yohlaselo kukuba inokubiza imali eninzi. Nangona kunjalo, isoftware ayizi ngexabiso eliphantsi ngokunjalo. Ngexesha lokufumana nawuphi na umonakalo kwiseva yakho yohlaselo, kuya kufuneka kuqala ubone ukuba kufuneka ubuye kangakanani idatha yakho. Nje ukuba umisele ixabiso ledatha yakho, unokuthatha isigqibo sokuba uyibuyisele ngokwakho idatha ngokusebenzisa isoftware, okanye kufuneka ubandakanye izandla zobuchwephesha zokwenza lo msebenzi. Musa ukuphelelwa lithemba ukuba ukubuyiswa kwedatha yakho yohlaselo kuyimfuneko kuwe. Lungiselela ukhetho lokufumana kwakhona idatha ukuze ungalahleki sisigidi semali ngenxa yokulahleka kwedatha okhe wahlangabezana nayo kutshanje.
