Ngaba ukudibanisa iindawo ezininzi kunokuhlangabezana neemfuno zakho zokugcina zangaphandle kwe-RAID?
Ingxowa yangaphandle ye-RAID yindlela eyaziwayo yokunyusa iikhompyutheni ezikhoyo ezigcinwayo ngeli xesha ungeze ukwanda kwendlela yokusebenza okanye ukukhuselwa kwedatha, okanye zombini. Enye yeemfuno eziphambili ukuphendula xa ufuna i-RAID yangaphandle yokugcina inkqubo yendlela eya kwenziwa ngayo, kwiprojekthi yesofthiwe okanye kwi-hardware ezinikezelweyo.
Kutheni i-RAID Inclosure yangaphandle?
Maye kucacile, ukuba injongo yakho eyona nto iphela nje yokwandisa isixa sendawo yokuqhuba i-drive, ungayifumana umqhubi omnye ongaphandle ungabi yinto ebiza kakhulu. Umqhubi wangaphandle ongenawo uphezulu kakhulu; ingasetyenziselwa indawo yokugcina eyongezelelweyo, njengendlela yokugcina ibhola, okanye ukufaka ezinye iinkqubo zokusebenza.
Ngakolunye uhlangothi, i-RAID esekelwe kuyo, iya kuklanywa ukuba ibambe ii-drive ezininzi kwaye inikeze umsebenzisi amandla okuqwalasela i-enclosure kwindawo enye okanye ngaphezulu kwe-RAID.
Fumanisa ngaphezulu kwinqaku: Yintoni i-RAID?
I-RAID izibophelelo zingalungiselelwa ukubonelela ngamanqanaba aphezulu asebenzayo kunokuba ayifumaneka kumatshini angatshatanga, angakwazi ukubonelela ngokuphindaphindiweyo kwedatha, ukuqinisekisa ukuba idatha yakho iyafumaneka nangona i-drive iyahluleka . Iiprogram ze-RAID nazo zinokuqwalaselwa kokubili ukusebenza kunye nokukhuselwa kwedatha.
Isoftware okanye i-Hardware Based RAID Controller
Inhliziyo yenkqubo ye-RAID ngumlawuli, owenza umyalelo wokusabalalisa idatha kunye nakwiimoto ezenza uluhlu lwe-RAID. Abalawuli be-RAID bangaba yi-hardware esekelwe, usebenzisa i-chip eyakhelwe kwi-RAID encane, okanye isofthiwe esekelwe, usebenzisa amandla okusebenzisa ikhompyutha yakho ukulawula indlela idilesi efundwayo okanye ebhaliweyo ngayo.
Ubulumko obuqhelekileyo beyekuba abalawuli be-hardware abancedisayo ekusebenzeni, bakwazi ukwenza izibalo ezifunekayo ukuba baqhube idatha kwi-drivers kwindawo ye-RAID ngaphandle kokungenisa inkcaso yokusebenza. Iinkqubo ezisekelwe kwiSofthiwe zivame ukubiza kakhulu kwaye zingenza ngokwaneleyo amanqanaba amathathu adumile ama-RAID, RAID 0 (i-Striped for speed) , RAID 1 (Idatha echanekileyo ye-redundancy) , kunye ne- RAID 10 (I-set mirrored of drivers striped) . Kodwa kwakukho imiba yokusebenza kunye namazinga amaninzi e-RAID.
Amanqanaba e-RAID aphakamileyo afana ne-RAID 3 kunye ne- RAID 5 ekhusele idatha ngokusebenzisa izibalo eziyinkimbinkimbi ukudala idatha yedityanelwe ebhaliweyo kunye ne-flow flow data ngexesha elinye libhekisiwe njengengxaki enkulu kwiinkqubo-based based software kwaye kwabangela ukuba amanqanaba okusebenza kunokuba kubonwe ngabalawuli be-RAID esekelwe kwi-hardware.
Nangona kunjalo, ukucwangciswa kweprograms yamanje kusetyenziswa ii-cores zokucwangcisa ezininzi, kunye neenkqubo zokusebenza zanamhlanje ezisebenzisayo ngeenkqubo eziphambili ze-processor ziye zaphelisa kakhulu isohlwayo sokusebenza kwiinkqubo ze-RAID-based based, ubuncinci kwiinqanaba ze-RAID ezi-0, 1, 3 , 5, no-10.
I-RAID-Based RAID
Iifayile ze-RAID ezisebenzisa ukulawulwa kwe-software-based zizinto ezilandelayo:
- Iindleko ezincitshisiwe: Ngenxa yokuba i-RAID yokufakela ingasebenzisa i-chipset ye-interface edibeneyo, iindleko zokuyila kunye nokuveliswa zigcinwa ziphantsi kwi-RAID edibeneyo. Iindleko zeSoftwe zingabonakala ziphantsi kangako, kuba iinkqubo ezininzi zokusebenza ziquka ukuxhaswa kwenkxaso yezona zixhobo ezisisiseko ze-RAID ngokuqhelekileyo 0, 1, 10. Ukuba ufuna i-RAID 3, okanye i-5, kukho iinkqubo zeprosoft software ezongeziweyo ezinokuthi zithathe ukunyamekela iimfuno zakho.
- Ukungqinelana: I-RAID-abalawuli be-RAID bavumela ukulungelelaniswa okukhulu ekuqwalaseleni ukuba nganye i drive ngaphakathi kwinqanaba liza kusetyenziswa. Kwimizuzu emine yokuhamba; Unokuba neenqwelo ezintathu ezilungiselelwe njengemigca eqhelekileyo yokusebenza, kunye ne-1 enkulu drive yokulondoloza. Unokuqwalasela kwakhona ii-drives ezine njengemigca emibili emelekileyo, iisethi ezimiselweyo zokuhlela iividiyo, kunye nesethi yokudibanisa kwiilayibrari ezahlukeneyo ze-multimedia. Ingongoma yinto yokuba indlela yokuqhubela kuyo ifakelwe ukusetyenziswa ngokupheleleyo.
- Ukusebenza: Iinkqubo ze-RAID ezisekelwe kwiSofthiwe ezisetyenziselwa iimpawu ezisisiseko okanye iimpawu ezifakwe kwii-arrays akunakwenzeka ukuba zibone isohlwayo senkqubo . Nangona kunjalo njengokuba inani leemoto ezisetyenzisiweyo kwi-array zikhula, okanye amanqanaba e-RAID ayenzileyo, ii-apps ze-RAID zisekhompyutha zingaqala ukuchaphazela ukusebenza kwenkqubo ye-RAID, kunye nokusebenza jikelele kwikhompyutha.
- Ubuso: I-RAID esekelwe kwi-Software isebenzisa enye okanye ngaphezulu kwe-CPU , kunye ne-RAM enokuchaphazela ezinye iinkqubo eziqhutywe kwikhompyutheni yakho. Ubungakanani befuthe kusekelwe kwizinga le-RAID elisetyenzisiweyo, kunye nenani leemoto ezenza uluhlu lwe-RAID.
- I-Bootable: Le ngxaki exubekileyo, isofthiwe ye-RAID isebenza kahle ngokubamba iqela ukusuka kwi-RAID, kwaye abanye banemiba. Ukuba izicwangciso zakho zibandakanya ukuhlawula kwi-RAID yakho qiniseka kwaye khangela ukuba isofthiwe ye-RAID uceba ukuyisebenzisa ukuxhasa ukuxhasa.
RAID-Based RAID
I-RAID izibhengezo ezisebenzisa umlawuli we-RAID-based based RAID zinempawu ezilandelayo:
- Iindleko: Ukuvalwa kwe-RAID okusekelwe kwi-Hardware kuyakuba ne-premium kwintengo ngokuqhathaniswa neendawo ezininzi zokungena kwi-bay ngaphandle kwenkxaso ye-RAID eyakhiwe kuyo. Noko ke, umehluko kwixabiso lingancinci. I-hardware eyisiSekelo ye-RAID exhasa nje i-drivers, i-mirrored okanye i-drives ezizimeleyo ine-premium yindleko encinci, ngelixa i-RAID ezilawulwa yi-hardware-based based support support and additional drives ngaphakathi kwinqanaba lexabiso lingaba ne-premium yexabiso elikhulu.
- I-Self-containing: Iifayile ze-RAID ezisekelwe kwi-Hardware zibonakala kwinkqubo yokusebenza yomkhosi njengediski enye. Oku kuvumela ukuba inkqubo ye-RAID ibe yinto ecacileyo kwikhompyutha exhunyiwe kuyo. I-upshot iisistimu ze-RAID ezisekelwe kwi-hardware zithuthwa kalula phakathi kweekhomputer kunye neenkqubo zokusebenza.
- Ukusebenza: Nangona i-software kunye ne-RAID esekelwe kwi-hardware ingaba neenombolo ezifanayo zokusebenza zamanqanaba asemgangathweni kunye nama-mirrored level, xa uhamba kwizinga eliphezulu ze-RAID, iinkqubo ze-hardware-based zivame ukugqithisa amanqanaba abo asekelwe kwi-software. Le ntsebenzo ephuculweyo ayigcini nje ekubhaliseni nasekufundeni idatha kodwa iphinda ibonise xa idatha ye-RAID idinga ukuvuselelwa ngenxa yokuhluleka komqhubi. Iinkqubo ze-RAID ezisisiseko se-Hardware zihlala zenza inkqubo yokwakha kwakhona ngokukhawuleza kwaye iinkqubo ezisekelwe kwesoftware.
- Ubusiso: Ukuvalwa kwe-RAID esekelwe ngaphandle kwee-hardware akufanele kuvelise impembelelo kwiprogram okanye i-RAM ngaphezulu kwikhomputha yombutho.
- I-Bootable: Ngokuqhelekileyo, iinkqubo ze-RAID ezisekelwe kwi-hardware zingasetyenziselwa njengoko inkqubo yakho yebhobhoji inikezela uxhulumaniso kwikhompyutheni yakho isebenzisa uhlobo lwefowuni ukuba inkqubo yokusebenza isekela ukukhupha. I-USB 3 ne-Thunderbolt ezibuchwephesha kufuneka ngokubanzi zikhunjulwe kodwa khangela ngeenkqubo zokusebenza kunye nomenzi wekhompyutheni ukuqinisekisa.
Iziphakamiso ze-RAID
- I-RAID esekelwe kwi-Software ifumana isithupha xa i-force yokuqhuba igcina ixabiso kunye nokusetyenziswa kwakho kwe-RAID kuya kugcinwa ku- RAID 0 (emicatshulwa), uRaid 1 (ikhonjiswe), okanye i-RAID 10 (Iisethi ezifakwe kwi-drivers) . Olu hlobo lwenkqubo ye-RAID lukhethi olufanelekileyo kubasebenzisi basekhaya abaya kusebenzisa inkqubo ye-RAID ngekhompyutha enye inkqubo.
- I-RAID esekelwe kwi-Hardware iyona nto ikhethiweyo kwi-setup i-RAID, ezinjenge-RAID 3 okanye i-RAID 5 ezibandakanya iimbambano zobungakanani eziveliswayo kwaye zifaniswe ngexesha langempela njengoko idatha ithunyelwa kuyo nakwiqela le-RAID. I-RAID esekelwe kwi-Hardware iyona nto ikhethekileyo kwisiseko se RAID 0 kunye ne-RAID 1 xa ufuna ukuba i-RAID idibeneyo ibe zimeleyo kwikhomputha yombutho, ikunike amandla okuhambisa inkqubo phakathi kweekhompyutha ezininzi.
