Arrays kōpae RAID: he aha te mea te reira a te aha he mea e tika ana?

Kua rongo He maha ngā kaiwhakamahi o te mea pēnei i te huānga kōpae RAID, engari i roto i te mahi whakaaro i tēnei wā torutoru rawa te iwi he aha te mea te reira. Otiia rite tahuri te reira i roto i, i reira he mea uaua i konei. Kia titiro tatou te mauri o te wā, e ko, i runga i te maihao, i runga i te pūtake o te ngā mōhiohio whakamārama mo te tangata toharite.

He aha e huānga kōpae RAID?

Hei timata, whakaaro te maimoatanga whānui tapaea e te mau papai ipurangi. Arrays kōpae - he pūnaha rokiroki katoa, arā, o te paihere o puku pakeke e rua, neke atu rānei, kaimahi, ki te whakapiki ake i ranei te tere o te whai wāhi ki te kōrero penapena, ranei mo te tāruarua, hei tauira, ina whakaora koe te kape tārua.

I roto i pei tenei nui te taha i roto i ngā o te tāutanga takahi kua kahore here. Te reira i katoa tei runga i te maha o ngā hononga tautoko e te kaupapa. Mau, he aha e whakamahia ngā huānga kōpae RAID? Ko reira utu ki te mōhio e i roto i te ahunga o te whanaketanga hangarau (mo puku ara pakeke), kua roa kua whakatotoka ratou i tetahi ira (tere muka o 7200 rpm. / Min, te rahi keteroki, ko D. na i runga i.). He okotahi i roto i tenei whakaaro, he tauira SSD anake, engari ratou anake ake i roto i te rōrahi hua te nuinga. I te wa ano i roto i te hanga o pūtukatuka RAM papa ranei fakalakalaka atu sino. Ko te kupu, i te whakamahi o te RAID-huānga kawea te hua mahi tipu ka whakauru i te puku kōpae mārō.

Arrays kōpae RAID: momo, whakaaro

Ko nga ngā huānga ratou, e taea te herenga wehea ratou e te maha whakamahia (0, 1, 2, me D. na i runga i.). Ka hāngai ia tau ki te whakatinanatanga o tetahi o nga mahi kī.

Ko te matua i roto i tenei whakarōpū he huānga kōpae ki te tau 0 me te 1 (huaina i, ka kia matau ai he aha), no te mea kua whakaritea a reira ki a ratou te raruraru matua.

A, no te te hanga huānga ki atu puku hono tuatahi ki te whakamahi i te tatūnga BIOS, te wahi i te wāhanga rewenatia katoa RAID whirihoranga, whakaturia he uara. He mea nui ki te mōhio e kia te puku hono rite te taua tawhā i roto i ngā o te rōrahi, atanga, hononga, keteroki, a na i runga i. D.

RAID 0 (tihore)

E ere hangaia kore huānga kōpae ki te tere te uru ki raraunga rongoa (tuhituhi ranei pānui). Ratou te tikanga e taea e i roto i te taupiri i rua ki te wha puku.

Otiia i konei te raruraru matua, ko e ka muku koe raraunga i runga i te kōpae, riro te reira, me etahi atu. tuhia te kōrero i roto i poraka tētahi i runga i ia kōpae, me he tika hautanga ki te maha o te puku te hua mahi (arā, e wha kōpae rua rite nohopuku rite e rua). Ko konei ko e pā ana te mate o te mōhiohio kei te anake ki te meka e kia te wae ki runga ki te puku rerekē, ahakoa ko te kaiwhakamahi te "Explorer," kite i te kōnae i roto i te whakaaturanga noa.

RAID 1

huānga kōpae ki te ti'araa kotahi no ki te kāwai o Hangarite (Hangarite), ka mahi ki te whakaora i te Tāritehia raraunga.

Te pakeke te korero, i roto i te āhuatanga i taua ngaro te kaiwhakamahi etahi mahi, engari ka taea e te mea tino mohio e ki te ngaro o ngā raraunga i tetahi wāhanga, ka penapena ratou i roto i tetahi.

RAID 2 me runga ake

Huānga ki tau 2 me runga ake he whakaaro rua. I runga i te ringa kotahi, e hangaia ratou ki te tuhi i te kōrero i runga i te tahi atu - whakamahia mō te hapa ako.

I roto i te mau parau te tahi atu, tenei momo o huānga rokiroki ngā nga kaha o RAID 0 me RAID 1, engari e kore e ngā kaiwhakamahi i roto i rorohiko oaoa i rongonui nui, ahakoa te pūtake mo to ratou mahi, ko te whakamahi o te waehere Hamming.

He aha te mea pai ki te whakamahi i roto i te mahi?

O te akoranga, ki te mahara tō rorohiko e ki te whakamahi i ngā hōtaka rauemi-kaha, pērā i ngā kēmu hou, he pai ki te whakamahi i ngā huānga o te RAID 0. Ki te mahi koe ki ngā mōhiohio nui ki te penapena i roto i tetahi ara, ka whai ki te tono ki te huānga RAID 1. I roto i te tirohanga o te meka e te paihere o tau e rua ranei, ake rongonui kihai i, takoto ratou whakamahinga e te kaiwhakamahi anake ranei. E te ara, te whakamahi o te ngohi null he mahi, me te i roto i te kaupapa e te kaiwhakamahi pinepine utaina nga kōnae rongorau ki te rorohiko, mea, kiriata waiata ki Auaumoka tiketike mo te MP3 paerewa FLAC ranei ranei.

I roto i te toenga ka whai ki te whakawhirinaki i runga i to ratou ake hiahia me ngā matea. Ko reira i tenei, a ka whakawhirinaki ki runga ki te whakamahi o te ngohi ngā. A, o te akoranga, ka tautuhinga kōpaki he pai ki te hoatu kōpae SSD hiahia he mea whakarite ki puku kōpae mārō tikanga e kua tīmatanga i tuhi teitei me te tere pānui. Engari me waiho ratou tino ōrite i roto i to ratou āhuatanga me ngā tawhā, he huinga o connectable kore noa e mahi ranei. A ko reira ko tetahi o te tikanga tino nui tenei. Na ko te mea e tika ana ki te whakarongo ki tenei āhuatanga.
