- 1. Okwu Mmalite RAID
- 2. RAID ndị nkịtị na-agụnye 0, 1, 5, na 10. Ka anyị kwuo banyere uru ha kpọmkwem
- 3. Gịnị bụ uru nke RAID maka ụlọ ọrụ kọmputa?
1. Okwu Mmalite RAID
A na-akpọkwa RAID Redundant Array of Disk nọọrọ onwe ya. Ọ bụ usoro nchekwa nke ọtụtụ diski ike mejupụtara. Ị nwekwara ike iche ya dị ka njikọ serial, na-ejikọta ha ọnụ. Ọ na-eme ka nkwụghachi data na ịdị adị site na ikesa data na ọtụtụ diski ike.
2. RAID ndị nkịtị na-agụnye 0, 1, 5, na 10. Ka anyị kwuo banyere uru ha kpọmkwem
1. RAID0 bụ ihe dị mfe nke na-echekwa data na ọtụtụ diski site na ọnyá. Ọ nweghị ike ịnye ụdị atụmatụ mgbapụta ọ bụla, nke pụtara na ọ bụrụ na data anyị mebiri emebi, enweghị ike iweghachi RAID0. Otú ọ dị, ọ nwere ike inye uru dị ka ịrụ ọrụ dị elu na-agụ na ide na iji nchekwa dị elu. RAID0 dabara adaba maka ụfọdụ sọftụwia nwere ezigbo arụmọrụ chọrọ mana ọ bụghị nke siri ike n'ihe gbasara nchekwa data.
2. RAID1 ka a na-akpọ mirroring. N'ikwu ya n'ụzọ dị mfe, diski ike abụọ na-edozi, mana naanị ị na-ahụ ike nke otu diski ike na kọmputa. A na-eji diski ike nke ọzọ maka nchekwa data. Mgbe diski ike na-arụ ọrụ dara, diski ike nke enyo ga-agụ data wee mejupụta oghere ahụ.
RAID1 dị nnọọ iche na RAID0. Ọ bụ iji mee ka nchekwa data dịkwuo elu site n'ichegharị data diski ike, iji nweta uru nke nchekwa na ịdị mma. Ọ nwere ọnụego nnabata zuru oke, mana ọnụ ahịa ya dị oke elu. A na-eji RAID1 maka ngwa nwere arụmọrụ ọgụgụ na ide usoro dị elu yana nchekwa data, dị ka nchekwa data nke faịlụ ọkwa nzuzo.
3. RAID5 bụ ọkwa kachasị. Ọ nwere ike iburu n'uche uru nke arụmọrụ nchekwa yana nchekwa data. Enwere ike ịghọta ya dị ka nkwekọrịta n'etiti 0 na 1, ọ bụkwa ihe ngwọta na arụmọrụ kachasị mma n'ozuzu ya. RAID5 nwere ike izute ọtụtụ mkpa nchekwa, na ọtụtụ ebe data na-eji RAID5.
4. RAID10 na-ejikọta uru nke RAID1 na RAID0. Ọ na-ebu ụzọ jiri diski ike abụọ mepụta onyonyo enyo, wee tụgharịa ya n'ime. Edere data nke RAID1 n'ụdị diski ike abụọ n'otu oge. Ọ bụrụ na otu diski ike mebiri emebi, diski ike nke ọzọ ka nwere ike ịga n'ihu na-arụ ọrụ, na-eme ka ọ rụọ ọrụ mgbe ọ na-ahụ maka nchekwa data. Agbanyeghị, ọnụego ojiji diski ike nke RAID10 bụ naanị 50%.
3.Kedu uru RAID dị maka kọmpụta ụlọ ọrụ mmepụta ihe?
1. Mụbaa ọnụego mbufe: Site na iji ọtụtụ diski n'otu oge, teknụzụ RAID nwere ike ịbawanye ọnụego mbufe data nke sistemụ nchekwa. Na ọnọdụ RAID, ọtụtụ draịva diski nwere ike ịnyefe data n'otu oge, na-enye ohere ịgụ na ide ọsọ dị elu.
2. Nye ntachi obi na-ezighị ezi: Teknụzụ RAID na-enye ntachi obi site na data redundancy na njehie nrụzi algọridim iji hụ na data ziri ezi na ntụkwasị obi. Ọ bụrụ na otu diski daa, sistemụ RAID nwere ike iji data dị na diski ndị ọzọ nwetaghachi data furu efu, ma ọ bụ weghachite site na nkwado ndabere.
3. Mụbaa ikike nchekwa: Site na teknụzụ striping, RAID nwere ike ịgbasa ma chekwaa data na ọtụtụ diski, si otú a na-abawanye ikike nchekwa. Dịka ọmụmaatụ, mgbe ijiri draịva siri ike 1TB abụọ iji mepụta ọnọdụ RAID 0, ike diski ahụ ga-adaba na 2TB.
