A Chii chinonzi RAID tekinoroji?

Munyika yemakomputa, tekinoroji yeRAID seti yematekiniki uye zviyero zvinoshandiswa kuvandudza mashandiro, kuwanikwa, uye kuvimbika kwemasisitimu ekuchengetedza data. RAID, iyo inomiririra "Redundant Array yeYakazvimirira Disks", inokutendera kuti ubatanidze akawanda madhiraivha mune imwechete inonzwisisika sisitimu inoita seimwe, ichipa zvakakosha zvakakosha maererano nekumhanya, kugona ⁢uye⁣ kuchengetedza data.

Mhando dzeRAID uye maitiro avo makuru

Kune akasiyana mazinga eRAID, imwe neimwe iine hunhu hwayo uye zvakanakira. Inonyanya kuzivikanwa ndeye RAID 0, RAID 1, RAID 5 uye RAID 10.

RAID 0 Iyo inozivikanwa seyero yekukanda uye inoratidzirwa nekukamura data kuita mabhuroko uye nekuagovera pane akasiyana hard drive panguva imwe chete, izvo zvinobvumira kukurumidza kuwana data uye kuwedzera kwekuverenga nekunyora nekukurumidza. Zvisinei, haina kupa redundancy, saka kana imwe ye disks ikakundikana, data yose icharasika.

RAID 1, kune rumwe rutivi, inobva pakudzokororwa kwedata, kureva kuti, data yega yega inonyorerwa kuma disks maviri akasiyana panguva imwe chete. Izvi zvinopa kopi chaiyo yedata rese, zvichipa chengetedzo yakakura uye kuwanikwa muchiitiko chekutadza.Zvisinei, zvinouya nemutengo maererano nehukuru hwekuchengetera, se ⁤ kaviri nzvimbo yekuchengetedza iyo data data.

RAID 5 Ndiyo nhanho inosanganisa mitsetse uye parity. Iyo data yakakamurwa kuita zvivharo uye yakagovaniswa mumadhisiki akasiyana, sezvakangoita muRAID 0, asi⁢ mune iyi ruzivo rweparity runowedzerwa kubvumidza kuvakwazve kwedata kana kukanganisa. ⁤Inopa chiyero chakanaka⁤ pakati pekuita, ⁤ kugona uye kuchengetedza data.

Pakupedzisira, RAID 10 Inobatanidza nheyo dze RAID 0 uye RAID 1. Zvishoma zvema disks mana zvinodiwa uye data yakakamurwa kuva mabhuroki, ayo anobva aratidzwa uye akagoverwa mumadhisiki akasiyana. Offers kuita kwepamusoro uye kuwanikwa kwepamusoro, asi ine mutengo wepamusoro maererano nehukuru hwekuchengetedza.

CONCLUSIONS

RAID tekinoroji yakakosha munzvimbo dzinodiwa kuita kwepamusoro, kuwanikwa uye kuchengetedza data. Kusarudza iyo yakakodzera RAID nhanho zvinoenderana nezvinodiwa uye zvekutanga zvemushandisi wega wega kana kambani.

Muchinyorwa chinotevera, isu tichanyura mune yega yega RAID nhanho uye tozokurukura nezvayo chaiwo mabhenefiti uye kufunga.

-Kusuma kune RAID tekinoroji⁢

RAID (Redundant Array ye⁢ Yakazvimirira Disks) tekinoroji inzira yekuchengetedza data⁢ inoshandisa akawanda hard drive kupa kuita kwepamusoro uye redundancy kana kukundikana. Panzvimbo pekutsamira pane imwe chete hard drive, RAID inogovera data mumadhisiki akawanda, inovandudza kuverenga nekunyora kumhanya. Pamusoro pezvo, tekinoroji iyi inopa kushivirira kukuru, izvo zvinoreva kuti kana dhisiki imwe ikatadza, data inogona kudzoserwa nekuvakazve ruzivo pane asara dhisiki.

Kune akasiyana mazinga eRAID, imwe neimwe iine maitiro ayo uye mabhenefiti. RAID 0, semuenzaniso, inoshandisa nzira inonzi striping kupatsanura data kuita mabhuroko madiki uye kuaparadzira pamadhisiki akawanda. Izvi zvinopa kuita kwakaringana sezvo data ichigona kuverengwa nekunyorwa zvakafanana. Zvisinei, inoshaya kukanganisa kushivirira, zvichireva kuti kana imwe disk ikakundikana, data yose icharasika.

Kune rimwe divi, RAID 1 inoshandisa nzira inozivikanwa se ⁤»mirroring» kugadzira kopi chaiyo ye data pane maviri kana anopfuura dhisiki. Izvi zvinogonesa hukuru hukuru dhata uye kuchengetedzwa, sekunge imwe yedhisiki yakundikana, data icharamba iripo pane yasara dhisiki kana dhisiki. RAID 1 inonyanya kukosha munzvimbo umo kuperera kwedata kwakakosha zvakanyanya, senge mune zvemari kana mabasa ekurapa. Muchidimbu, tekinoroji yeRAID inopa mhinduro inoshanda uye yakavimbika yekuchengetedza data, inovandudza zvese mashandiro uye kuchengetedza ruzivo.

-Marudzi eRAID zvigadziriso

RAID zvigadziriso, acronym yeRedundant Array yeYakazvimirira Disks⁢, isethi yetekinoroji inobvumira akawanda ekuchengetedza zvikamu kuti abatanidzwe kuvandudza kuvimbika uye/kana kuita kwehurongwa. Nechinangwa chekugadzirisa kushandiswa zvema hard driveKune marudzi akasiyana eRAID magadzirirwo. Aya magadzirirwo anosiyaniswa nemafambisirwo anoitwa data mumadhisiki uye nzira yekutadza kunoitwa.

Rudzi rwekutanga rwe RAID configuration i⁢ RAID 0. Mukugadzirisa uku, data yakakamurwa kuita mabhuroko uye inochengetwa pamadisks maviri kana anopfuura⁤ anoenderana. madhisiki akawanda panguva imwe chete. Nekudaro, iyi gadziriso haipe redundancy, zvichireva kuti kana imwe yedhisiki ikatadza,⁤ data rese rakachengetwa pa⁢ array richarasika.

Rudzi rwechipiri rwekugadzirisa ndeye RAID 1, inozivikanwawo se "mirroring". Muchiitiko ichi, data inonyorerwa kune imwe dhisiki uye yakanyatsokopwa kune imwe dhisiki, ichigadzira kopi yakafanana. Iyi gadziriso inopa yakakwira redundancy, sezvo kana imwe yedhisiki ikatadza, iyo data icharamba iripo pagirazi disk. RAID 1 ine kuverenga kwakanaka kwekuita, asi kunonoka kunyora kuita pane mamwe marudzi eRAID magadzirirwo nekuda kwekudiwa kwekunyora data kune ese madhisiki.

Rudzi rwechitatu rwekugadzirisa ndeye RAID 5. Mukugadzirisa uku, data inogoverwa ⁢muma disks akawanda⁢ pamwe chete nemashoko ekuenzanisa. Ruzivo rweParity runokutendera kuti ugadzirezve data rakarasika kana dhisiki yakundikana. RAID 5 inopa chiyero chakanaka pakati pekuita uye redundancy, sezvo inobvumira kuverenga nekunyora kunonzwisisika uye inobvumirawo kudzoreredza data muchiitiko chekutadza kwe diski.

Yakanyanya kuwanda ⁣ RAID mazinga

Kune akati wandei mazinga eRAID anopa akasiyana madhigirii ekubudirira, kukanganisa kushivirira, uye optimized mashandiro ekushandisa kwakasiyana. Pano, tichakurukura nezve yakanyanya kuwanda RAID mazinga inowanikwa muzvirongwa zvakawanda zvekuchengetedza.

1. RAID ⁢0: Iyi nhanho yeRAID yakavakirwa pakugoverwa⁢ kwedata mumadhisiki akawanda pasina ⁣dundancy. Iyo data yakakamurwa kuita mabhuraki uye yakachengetwa pamadhisiki akasiyana, ayo inovandudza kushanda nekubvumira dhisiki kushanda panguva imwe chete pamabasa akasiyana. Zvisinei haipi kushivirira kukanganisa, zvinoreva kuti kana dhisiki imwe chete ikakundikana, inogona kuguma nekurasikirwa kwe data.

2. RAID 1: Iyo inozivikanwawo semirroring, RAID level 1 inotarisa pane data⁢ redundancy. Panhanho iyi, data rinonyatsokopwa pamadisiki maviri⁤ kana anopfuura, kugadzira replica chaiyo. kuvandudzwa kwekuvimbika uye kushivirira kukanganisa, sezvo kana dhisiki ikakundikana, data inogona kudzoserwa kubva pagirazi dhisiki. Nekudaro, iyi RAID nhanho haipe yakakosha kuvandudzwa kwekuita.

3. RAID 5: Iyi⁢ RAID level inosanganisa performance uye redundancy. Inoshandisa yakagovaniswa parity⁣ kuchengetedza data uye ruzivo⁤ runogoverwa pamadhisiki ese. Izvi zvinoreva kuti kana pane kukundikana pane imwe dhisiki, iyo data inogona kuvakwa zvakare uchishandisa ruzivo rweparity. RAID 5 inoshandiswa zvakanyanya nekuda kwechiyero chayo pakati pekuita uye kukanganisa kushivirira, kunyangwe ichigona zvakare kuve nemhedzisiro pakumhanya kwekunyora nekuda kwehuwandu hwekuverenga.

-Zvakanakira uye zvakaipira kushandisa RAID

RAID (Isina Basa ⁢Array yeMadhisiki Akazvimirira) tekinoroji yekuchengetera inosanganisa akawanda madhiraivha kuita imwechete sisitimu, inopa hukuru hukuru, chengetedzo, uye kuita. ⁢Kunyangwe iine zvakawanda zvakanaka, inewo zvimwe zvayakaipira zvatinofanira kufunga nezvazvo tisati tazviita.

Ngatitarisei mamwe mabhenefiti ekushandisa RAID:

• Kuwedzera kuchengetedza: Nekubatanidza akawanda madhiraivha akaomarara, RAID inopa yakakura kwazvo kuchengetedza kupfuura dhiraivha imwe chete, ichibvumira huwandu hukuru hwe data kuchengetwa pasina matambudziko.
• Yakawedzera data⁤ chengetedzo: RAID inopa redundancy, zvinoreva kuti data inokopwa pamadhisiki akawanda. Izvi zvinopa dziviriro kubva mukutadza kwehard drive,⁤ sezvo ⁢data rinogona kutorwa kubva kune asara madhiraivha.
• Kuita kwakanakisa: RAID inoshandisa hunyanzvi hwakadai se ⁤data ⁢rout⁢ uye ⁢kuenzanirana kwe ⁤kuverenga/kunyora mashandiro kuti kukurumidze kuwana data, zvichikonzera ⁤kuwanda kwese ⁤kushanda kwesystem.

Zvisinei nemabhenefiti ataurwa, pane zvakare zvimwe zvipingamupinyi zvekushandisa RAID:

• Mariro: Kuita RAID⁤ kunogona kudhura, kunyanya kana ⁣specialized hardware ichidikanwa. Pamusoro pezvo, kuchengetedza uye kutsiva madhiraivha anogona kudhura⁤ mukufamba kwenguva⁤.
• Kuoma kunzwisisa: Kugadzirisa uye kugadzirisa RAID system inogona kuve yakaoma, sezvo ichida ruzivo rwepamusoro pehunyanzvi. Uyezve, kudzoreredza data muchiitiko chekutadza kwakawanda kwedhisiki kunogona kuve kwakaoma uye kutora nguva.
• Kuita kushoma mune mamwe mamiriro: Kunyangwe RAID ichipa kuvandudzwa kwekuita kwese, mune mamwe mamiriro, akadai seyakaomesesa kuverenga / kunyora mashandiro, kuita kunogona kushomeka nekuda kwekudiwa kwekuyananisa madhisiki.
