1. Nhanganyaya kuRAID
2. MaRAID akajairwa anosanganisira 0, 1, 5, uye 10. Ngatitaurei nezve zvakanakira iwo
3. Ndeapi mabhenefiti eRAID kumakomputa eindasitiri?

1. Nhanganyaya kuRAID

RAID inodaidzwa zvakare kuti Redundant Array yeYakazvimirira Disks. Iyo igadziriro yekuchengetedza inoumbwa nemadhisiki akawanda akaomarara. Iwe unogona zvakare kufunga nezvayo se serial yekubatanidza, uchivabatanidza pamwechete. Iyo inovandudza data redundancy uye kuwanikwa nekugovera data pane akawanda hard disks.

RAID inogona kupa zvinotevera mabasa:

1. Batanidza nzvimbo mbiri kana kupfuura yakaoma dhisiki mune yakazara kuti uwedzere dhisiki yekuverenga chiyero.

2. Kuvandudza kushivirira kwemhosva; kukanganisa kushivirira kunoreva kuti kana iyo data yakanganiswa, unogona kudzoreredza data rakakuvadzwa kana ukaisa RAID (kunze kweRAID0)

Standard RAID level:

RAID yakakamurwa kuita RAID0, RAID1, RAID2, RAID3, RAID4, RAID5, RAID6. Aya mazinga manomwe ndiwo akajairwa RAID, ayo anozivikanwa zvakare neindasitiri. Iyo yakajairwa nhanho ndiyo inonyanya kukosha RAID kumisikidzwa seti, uchishandisa matekinoroji akadai sedhata striping kana girazi. Aya mazinga akajairwa eRAID anogona kusanganiswa, uye iyo yakasanganiswa RAID ichave nekuita kwepamusoro, chengetedzo, uye kuvimbika.

2. MaRAID akajairwa anosanganisira 0, 1, 5, uye 10. Ngatitaurei nezve zvakanakira iwo

1. RAID0 iri nyore inochengeta data pane akawanda disks kuburikidza nemitsara. Iyo haigone kupa chero nzira yeredundancy zano, izvo zvinoreva kuti kana data redu rakakuvadzwa, RAID0 haigone kudzoserwa. Nekudaro, inogona kupa mabhenefiti akadai seyepamusoro kuverenga nekunyora kuita uye kushandiswa kwekuchengetedza kwakanyanya. RAID0 inowanzo fanirwa kune imwe software ine zvirinani kuita zvinodiwa asi isina kuomarara maererano nekuchengetedza data.

2. RAID1 inonzi mirroring. Zvichitaurwa zviri nyore, madhisiki maviri akaomarara akashongedzwa, asi iwe unongoona huwandu hweimwe hard disk mukombuta system. Imwe hard disk inoshandiswa kuchengetedza data. Kana iyo inoshanda hard disk ikakundikana, iyo mirrored hard disk ichaverenga data uye kuzadza gap.

RAID1 inongopesana neRAID0. Iko kuwedzera kuchengetedzeka kwedata nekutarisa iyo hard disk data, kuitira kuti uwane zvakanakira kuchengetedza uye nyore. Iyo ine yakakwana yekutadza kushivirira mwero, asi mutengo wakanyanya kukwirira. RAID1 inoshandiswa kune maapplication ane yakanyanya kutevedzana kuverenga nekunyora kuita uye kuchengetedzwa kwedata, sekuchengetedzwa kwedata kwemafaira ekuvanzika-chikamu.

3. RAID5 ndiyo yakanyanya kuwanda. Inogona kufunga nezvezvakanakira kuchengetedza kuita uye kuchengetedzwa kwedata. Inogona kunzwisiswa sekubvumirana pakati pe0 ne1, uye ndiyo mhinduro ine yakanakisa kuita kwese. RAID5 inogona kusangana nezvakawanda zvekuchengetedza zvinodiwa, uye nzvimbo zhinji dzedata dzinoshandisa RAID5.

4. RAID10 inobatanidza zvakanakira RAID1 uye RAID0. Iyo inotanga kushandisa madhisiki maviri akaomarara kugadzira mufananidzo wegirazi, uye wozoishandura kubva mukati. Iyo data yeRAID1 inonyorerwa kune maviri hard disk arrays panguva imwe chete. Kana imwe hard disk ikakuvadzwa, imwe hard disk inogona kuramba ichishanda, ichiva nechokwadi chekushanda uku ichichengetedza data kuchengetedzwa. Zvisinei, iyo hard disk utilization rate yeRAID10 inongova 50%.

3.Ndeapi mabhenefiti eRAID kumakomputa emaindasitiri?

1. Wedzera chiyero chekuendesa: Nokushandisa madhisiki akawanda panguva imwe chete, teknolojia yeRAID inogona kuwedzera zvakanyanya dhidhiyo yedhidhiyo yekuchengetedza. Mune RAID modhi, akawanda dhisiki madhiraivha anogona kutamisa data panguva imwe chete, achibvumira kwepamusoro kuverenga nekunyora kumhanya.

2. Ipa kukanganisa kushivirira: RAID tekinoroji inopa kukanganisa kushivirira kuburikidza nedata redundancy uye kukanganisa kugadzirisa algorithms kuve nechokwadi chekuvimbika kwedata uye kuvimbika. Kana dhisiki rimwe rikatadza, RAID system inogona kushandisa data pane mamwe madhisiki kudzoreredza data rakarasika, kana kudzoreredza kubva kune backup.

3. Wedzera simba rekuchengetedza: Kuburikidza nemichina yekugadzira, RAID inogona kuparadzira uye kuchengeta data pamadhisiki akawanda, nokudaro kuwedzera simba rekuchengetedza. Semuenzaniso, mushure mekushandisa madhiraivha maviri e1TB kugadzira RAID 0 modhi, dhisiki simba rinozogara ku2TB.

4. Pfupiso:

Vanhu vanoda kushandisa tekinoroji yeRAID vanowanzova avo vanoda kugadzirisa huwandu hwakawanda hwe data, kutsvaga kuita kwepamusoro uye kuvimbika, uye vane zvinodiwa zvakanyanya zvekuchengetedza data.

Unogona kufarira SINSMART zvigadzirwa zvakakurumbira:

Indasitiri inotakurika komputa

Industrial rackmount pc

Military laptop iri kutengeswa
