Kukanganisa Kunotsungirira Nokutsanya Verenga Nguva
RAID 5 iri kurwisa RAID chirongwa chakakonzerwa kuwedzera kukurumidza kwema disk uye inonyora. RAID 5 yakafanana neR RAID 3 pakuti inoshandisa bumbi bit kuti ibatsire kuchengetedza duramazwi. Zvisinei, kusiyana neR RAID 3, iyo inoshandisa diski yakatsaurirwa kuchengetedza hukama, RAID 5 inoparadzanisa hutano kune dzose dzinofambisa mumutambo.
RAID 5 inopa motokari kukanganisa kushivirira, zvichibvumira chero imwe yega motokari mumakwikwi kuti ikundike pasina kurasikirwa chero dhenda iri muzvirongwa. Apo motokari inokundikana, RAID 5 yakawanda inokwanisa kushandiswa kuverenga kana kunyora deta. Kana imwe chete iyo isina kukwira motokari ishandiswa, RAID 5 yakawanda inogona kupinda maitiro ekudzosa mafashoni, uko ruzivo rwepadhesi iri muchikwata runoshandiswa kuvaka zvakare ruzivo rwakashayikwa pane ganda rachangobva kuiswa.
Kuverenga RAID 5 Array Size
RAID 5 mabhii anoshandisa zvakaenzana nefambisi yekuchengetedza parity, zvinoreva kuti huwandu hwehuwandu hwakafanana hunogona kuverengwa kuburikidza neshoko rinotevera:
S = d * (n - 1)
I "d" ndiyo yakadukusa disk usayizi mukati, uye "n" ndiyo nhamba ye disks inoumba.
Kushandisa Zvakanakisisa RAID 5
RAID 5 chisarudzo chakanaka chema multimedia file yekuchengetedza. Kuverenga kwayo kunogona kuve kwakakwirira, asi kukurumidza kunyorera kunonoka zvishoma, nekuda kwekudiwa kwekuverenga nekuparadzira hukama. RAID 5 inonyanya kukoshesa kuchengeta mafaira makuru, uko data inowanikwa sequentially. Zviduku, zvakasangana nemafaira zvinoshandiswa pakuverenga zvinyorwa, uye kunyora kushanda kunogona kuva varombo nekuda kwekudiwa kwekugadzirisa zvakare nekudzorerazve ruzivo rwehutano hwebasa rimwe nerimwe rekunyora.
Kunyange zvazvo RAID 5 inogona kushandiswa nehukuru hwakasiyana-siyana, iyo haifaniri kutaridzirwa nenzira yakasarudzwa sezvo RAID 5 yakakura sarudzo icharondedzerwa nediki duku disk mumutsetse (ona fomu iri pamusoro).
Pamusana pekuda kwekuita maonero ehurumende uye kugovera kuwanikwa kwakaguma, RAID 5 inonyanya kuitika kana yakagadzirwa mu hardware-based RAID inodzivirira. App yeDisk Utility yakabatanidzwa ne OS X haitsigire kusika software-based RAID 5 arrays, zvisinei, SoftRAID, kubva kumusana wechitatu weSoftRAID, Inc., inogona kushandiswa kana chirongwa che-software-based ichidiwa.
