Tau multi-bay enclosure raws li koj xav tau kev pab sab nraud RAID?
Ib qho chaw sab nraud RAID yog ib txoj hauv kev nyiam ua kom koj cov computers muaj kev cia thaum tseem muab kev nce qib lossis kev tiv thaiv cov ntaub ntawv, los yog ob qho tib si. Ib qho ntawm cov lus nug tseem ceeb uas yuav tau teb thaum nrhiav lwm qhov RAID cia yog qhov ua haujlwm RAID yuav ua licas, hauv software lossis los ntawm kev kho mob siab.
Vim li cas ib sab RAID Enclosure?
Peb yuav tsum paub meej, yog tias koj lub hom phiaj tseem tsuas yog los nthuav cov nqi ntawm qhov chaw tsav, koj yuav pom ib tus tsav sab nraud kuj yuav tsis tshua muaj nqis. Tsav tus tib sab nraud txawv heev; nws tuaj yeem siv rau qhov chaw cia ntxiv, raws li tus neeg tsav tsheb, los yog kev txhim kho lwm txoj haujlwm khiav haujlwm.
Ib lub RAID raws qhov thaiv, ntawm qhov tod tes, yuav raug tsim los tuav cov tsav ntau yam thiab muab tus neeg siv lub peev xwm los txhim kho qhov kev thaiv hauv ib qho los yog ntau dua RAID teeb tsa.
Nrhiav ntau ntxiv hauv tsab xov xwm: RAID yog dab tsi?
RAID enclosures tuaj yeem tsim kho kom yooj yim dua cov kev ua tau zoo dua li qhov muaj feem xyuam ntawm cov tsav tsheb loj, lawv tuaj yeem muab rau cov ntaub ntawv ntxiv, kom ntseeg tau tias koj cov ntaub ntawv tseem muaj txawm tias tsav tsis tau . RAID systems kuj yuav raug teeb tsa rau kev ua haujlwm thiab cov ntaub ntawv tiv thaiv.
Software lossis Ruaj Ntseg Raws Li RAID
Lub plawv ntawm lub RAID system yog tus maub los, uas yuav siv cov lus txib ntawm kev faib cov ntaub ntawv mus thiab los ntawm cov tsav tsheb uas ua rau RAID array. RAID controllers yuav ua tau raws li kev siv ua ntu, siv lub chip built-in rau RAID enclosure, lossis software based, siv lub tshuab computer ntawm koj lub computer los tswj cov ntaub ntawv nyeem los yog sau rau hauv daim ntawv ceeb toom.
Cov tswv yim zoo tshaj plaws yog cov cuab yeej sib tw ua kom muaj qhov sib txawv hauv kev ua tau zoo, muaj peev xwm ua kom cov lus teb yuav tsum tau coj los qhia txog thiab tawm ntawm cov neeg tsav tsheb hauv RAID array uas tsis muaj kev sib tw nrog kev ua haujlwm. Cov kev software-raws li feem ntau yeej tsis tshua kim thiab yuav ua tau zoo rau peb qib RAID qib siab, RAID 0 (Striped for speed) , RAID 1 (Cov ntaub ntawv Mirrored rau redundancy) , thiab RAID 10 (Txheej Txheem Txheej Txheem Txuj Ci) . Tab sis muaj teeb meem kev kawm nrog ntau txoj haujlwm RAID.
Advanced RAID qib siab xws li RAID 3 thiab RAID 5 uas tiv thaiv cov ntaub ntawv los ntawm kev siv cov lus teb los ua cov ntaub ntawv sib npaug uas tau muab sau nrog cov txheej txheem ntawm cov ntaub ntawv tam sim no yog nyob rau ntawm ib lub sij hawm suav tias yog ntau dhau ib hom kev lag luam software thiab ua rau qis dua kev ua tau zoo tshaj qhov tau pom nrog kho vajtse raws li RAID controllers.
Txawm li cas los xij, niaj hnub siv tus qauv tsim siv ntau lub cores, nrog rau kev ua haujlwm nruab nrab niaj hnub uas coj kom zoo dua ntawm cov tub ntxhais kev ua haujlwm tau zoo nkauj npaum li cas tshem tawm kev ua haujlwm hauv software raws li RAID systems, tsawg kawg rau cov theem pib RAID theem ntawm 0, 1, 3 , 5, thiab 10.
Software-Raws li RAID
RAID systems uas siv cov software-based tswj muaj cov nram qab no cov yam ntxwv:
- Txo tus nqi: Vim tias RAID enclosure yuav ua rau siv tus qauv hauv chipsets, tsim thiab tsim cov nqi raug khaws tseg cia rau qhov RAID enclosure. Tus nqi software kuj yuav tsawg li xoom, vim tias muaj ntau qhov kev khiav haujlwm muaj xws li kev txhawb nqa rau feem ntau hauv kev yooj yim RAID feem ntau yog 0, 1, 10. Yog tias koj xav tau RAID 3, los yog 5, muaj cov nqi software ntxiv uas muaj peev xwm siv kev saib xyuas ntawm koj cov kev xav tau.
- Versatility: Raws li software RAID controllers cia qhov yooj yooj yim tshaj plaws hauv kev txhim kho txhua tsav hauv ib qho kev tiv thaiv. Hauv ib daim pib tsav tsheb plaub; koj tuaj yeem muaj peb lub ntsiab lus txhim kho tau raws li cov hlua khauj khaum rau kev ua haujlwm, thiab 1 loj rau kev thaub qab. Koj tuaj yeem tsim kho plaub lub tshav dav hlau uas yog ob qho uas muaj kev ywjpheej, ib qho teebmeem rau kev yees duab editing, thiab muaj ntau yam khoom siv sib txig sib txig. Tus taw tes yog tias qhov kev tsav tsheb nyob hauv qhov chaw nkaum yog siv li cas rau koj.
- Kev Ua: Kev RAID raws li qhov software siv rau cov kab kos striped los yog cov qauv ntawm cov mirrored yuav tsis pom qhov kev nplua . Txawm li cas los xij vim tias cov tsav tsheb siv hauv ib qho kev loj hlob tuaj, los yog ntau txoj hauv kev RAID, software raws RAID apps yuav pib rau kev ua haujlwm ntawm RAID system, thiab tag nrho kev ua tau zoo ntawm lub computer.
- Nyiaj siv ua haujlwm: RAID raws li qhov software ua rau siv ib los sis ntau dua CPU cores , nrog rau RAM uas yuav cuam tshuam lwm cov dab khiav ntawm koj lub computer. Qhov cuam tshuam ntawm qhov cuam tshuam yog nyob ntawm RAID qib siv, thiab tus naj npawb ntawm cov xuaj moos uas tsim tawm RAID array.
- Bootable: Qhov no yog ib qho sib xyaw sib xyaw, ib txhia RAID software ua haujlwm zoo nrog booting los ntawm RAID array, thiab lwm tus muaj teeb meem. Yog tias koj lub hom phiaj muaj kev sib tw nrog koj tus RAID array nco ntsoov thiab xyuas tias RAID software koj npaj yuav siv cov kev txhawb nqa booting.
Kho Khoom Siv RAID
RAID daim npav uas siv lub RAID xws li khoom siv raws li muaj cov nram qab no:
- Nqi: RAID cov ntaub ntawv kho mob raws li yuav tau them tus nqi hauv cov nqi piv rau cov nqi nplua nuj uas tsis muaj RAID kev pab tsim los. Txawm li cas los, qhov txawv ntawm qhov nqi yuav me me. RAID yooj yim kho uas tsuas yog txhawb nqa striped, iav los yog kev tsav sab nraud muaj ib tus nqi them me me, thaum kho vajtse RAID controllers uas txhawb ntxiv RAID ntau ntau thiab ntau tsav hauv lub array kuj muaj nqi ntau dua.
- Yus tus kheej: Cov cuab yeej hluav taws xob raws RAID systems tshwm rau cov lag luam khiav lag luam ua ib zaug xwb. Qhov no tso cai rau RAID system kom pob tshab rau hauv lub computer nws txuas nrog. Tus upshot yog kho raws li RAID systems tau yooj yim ntawm cov computers thiab operating systems.
- Kev Ua Zoo: Thaum software thiab hardware-based RAID yuav muaj cov lej zoo sib xws rau cov theem pib sau tseg thiab ntau dua, thaum koj tsiv mus rau ntau dua RAID ntau ntau, cov cuab yeej hardware-based yuav tsum ua zoo tshaj lawv cov software sib xws. Qhov kev ua tau zoo tuaj no tsis yog tas rau kev sau ntawv thiab kev nyeem cov ntaub ntawv nkaus xwb, tab sis kuj qhia tau tias thaum cov ntaub ntawv RAID yuav tsum tau rov qab tsim dua vim kev tsav tsheb tsis ua haujlwm. Cov cuab yeej hluav taws xob raws RAID feem ntau ua rau txoj kev rov txhim kho dua sai dua ces software raws li lub tshuab.
- Kev Them Nqi Khoom: RAID qhov hluav taws xob sab nraud yuav tsum ua rau tsis muaj kev cuam tshuam ntawm processor lossis RAM nyiaj siv ua haujlwm ntawm lub tshuab computer.
- Bootable: Feem ntau, RAID cov cuab yeej hluav taws xob yuav siv tau los ntawm koj qhov system boot muab kev txuas rau koj lub computer siv hom chaw nres nkoj uas lub operating system txhawb nqa ntawm. USB 3 thiab Thunderbolt cov chaw nres nkoj yuav tsum yog feem ntau yuav tsum tau khij tawm, tiamsis khij nrog lub operating system thiab lub tshuab computer kom paub meej.
RAID Cov lus pom zoo
- Kev RAID raws li software tau txais ib tus ntiv tes xoo thaum lub zog quab yuam kom txo nqi thiab koj qhov kev pabcuam RAID yuav txwv tsis pub mus rau RAID 0 (striped), Raid 1 (raug rho tawm), lossis RAID 10 (Tsav ntawm cov kab txaij) . Hom kab ke no RAID yog qhov kev xaiv zoo rau cov neeg siv hauv tsev uas yuav siv RAID system nrog ib qho computer system.
- Hardware-based RAID yog qhov kev xaiv rau ob qho xws li RAID setups, xws li siv hauv RAID 3 los yog RAID 5 uas sib koom ua ke cov khoom sib koom ua ke thiab muab piv rau cov sij hawm ua tiag raws li cov ntaub ntawv xa mus rau thiab los ntawm RAID array. Hardware-based RAID kuj yog ib qho kev xaiv zoo rau RAID 0 thiab RAID 1 systems ntxiv thaum koj xav kom RAID enclosure ywj siab ntawm lub tshuab computer, muab koj lub peev xwm los mus kaw qhov system ntawm ntau cov computers.
