Iyini i-RAID 5?

I-RAID 5 iyindlela yokugcina idatha kumadiski amaningi. Isebenzisa idatha yokulinganisa ukuze igcine ulwazi luphephile. Lokhu kusetha kudinga okungenani amadiski amathathu ukuze kusebenze kahle.

Iqinisekisa ukuthi uhlelo luqhubeka nokusebenza noma ngabe idiski eyodwa yehluleka. Lokhu kungenxa yokuthi i-RAID 5 isabalalisa idatha kanye nokulingana kuwo wonke amadiski.

I-RAID 5 isebenzisa ukusebenza kwe-XOR ngokulingana. Lokhu kusho ukuthi idatha nokulingana kuhlala kuvumelana. Ilinganisa ukusebenza kahle kwesitoreji nokuphepha kwedatha, okwenza ukufunda kusheshe.

Kodwa, ukubhala idatha kunganciphisa ijubane. Lokhu kungenxa yokuthi i-RAID 5 kufanele ibale kabusha ukulingana ngezinye izikhathi. Ngemuva kokwehluleka kwediski, kuthatha isikhathi ukwakha kabusha idatha. Lokhu kungenza isistimu ihambe kancane ize ilungiswe. ukuhlasela-5-raid-6

Iyini i-RAID 6?

I-RAID 6 iwubuchwepheshe bezinga eliphezulu lokugcina idatha obugcina idatha yakho iphephile. Isebenzisa ukulinganiswa okumbaxambili ukuze ivikele ekulahlekeni kwedatha. Lokhu kusho ukuthi ungalahlekelwa amadiski amabili ngesikhathi esisodwa futhi ugcine idatha yakho iphephile.

Lona ukhiye wezindawo ezidinga idatha yazo njalo itholakala futhi iphephile. Ilungele izindawo ezingakwazi ukulahlekelwa idatha.

I-RAID 6 isabalalisa idatha kuwo wonke amadiski anezinhlobo ezimbili zokulingana. Lokhu kuyenza ihluke ku-RAID 5, eneyodwa kuphela. Ngamaphathi amabili, i-RAID 6 yenza isiqiniseko sokuthi idatha yakho iphephile ngisho nalapho amadiski ehluleka.

Ukusebenzisa i-double parity kunciphisa isivinini sokubhala idatha kancane. Kodwa, kuwufanele ukugcina idatha yakho iphephile. Lokhu kuyiqiniso ikakhulukazi kumabhizinisi adinga ukugcina idatha yawo ivikelekile.

I-RAID 6 yinhle kakhulu ezindaweni lapho idatha ibaluleke kakhulu. Lokhu kuhlanganisa amabhange nezibhedlela.

Ukuze uyisonge, i-RAID 6 ithuthukisa ukuphepha kwedatha ngokulingana okumbaxambili. Kuyinketho eqinile yokugcina idatha iphephile futhi kulula ukuyibuyisela.

Sengiphetha, ukukhetha phakathi kwe-RAID 10 nesitoreji samafu kuncike ezidingweni zebhizinisi lakho. Ukwazi umehluko kusiza ukwenza izinqumo ezingcono zokuphathwa kwedatha.

Ungakukhetha Kanjani Ukucushwa Kwe-RAID Okulungile Kwezidingo Zakho

Ukukhetha ukulungiselelwa okulungile kwe-RAID kumayelana nokuqonda izidingo zakho zokugcinwa kwedatha. Kufanele ucabange ukuthi ingakanani idatha okudingeka uyigcine nokuthi udinga ngokushesha kangakanani ukuyifinyelela. Isibonelo, uma uphatha imininingwane egciniwe emikhulu futhi udinga ukufinyelela okusheshayo, i-RAID 10 ingase ibe inketho engcono kakhulu. Uma usebenza ne- I-PC yezimboni ene-GPU ngemisebenzi ejulile yokucubungula, ukuba ne-RAID yokucushwa esekela ukudluliswa kwedatha ephezulu kungaba yinzuzo ngokukhethekile.

Ngakolunye uhlangothi, uma ubheke ukwandisa isitoreji ngesivinini sokufunda esihloniphekile, i-RAID 5 ingaba yindlela okufanele uhambe ngayo. Kubalulekile ukucabangela ibhajethi yakho futhi. Uhlobo ngalunye lwe-RAID lunezindleko zalo, ngakho khetha oluhambisana nohlelo lwakho lwezezimali. Kulabo abadinga izixazululo ezimangelengele, a ikhompyutha ye-rackmount eqinile inikeza izinketho ezihlala isikhathi eside ezingavumela ukucushwa okuhlukahlukene kwe-RAID.

Esinye isici esiyinhloko ukuthi bungakanani ubungozi ozimisele ukubuthatha. Uma ukulahlekelwa idatha kuwukukhathazeka okukhulu, i-RAID 6 iyindlela enhle, enikeza ukuvikeleka okwengeziwe ekuhlulekeni kwedrayivu. Lokhu kungabaluleka kumadivayisi afana amaphilisi aqinile ane-Windows 11 esetshenziswa ezindaweni ezinokhahlo lapho ukuthembeka kwedatha kubalulekile.

Cabanga ukuthi udinga ngokushesha kangakanani ukubuyisela idatha ngemuva kokwehluleka. Ngokwesibonelo, usebenzisa i I-Advantech PC yezimboni ingasiza ekuqinisekiseni ukululama okusheshayo ngenxa yokwakheka kwayo okuqinile kwehadiwe. Uma isikhala siyisithiyo, cabanga a I-PC ye-rack engu-1U enikezela ngamakhono okugcina idatha ahlangene kodwa anamandla.

Ekugcineni, cabanga ngezidingo zakho zedatha zesikhathi esizayo. Uma idatha yakho ikhula, khetha i-RAID engakhula nawe. Ngokucabangela izidingo zakho ngokucophelela, ungakhetha i-RAID evikela idatha yakho kahle futhi iyigcine ifinyeleleka manje nasesikhathini esizayo. Ukuze uthole izidingo ezengeziwe zekhompuyutha ephathwayo noma ekude, ama-laptops aqinile ayathengiswa hlinzeka ngezinketho eziguquguqukayo nezihlala isikhathi eside.
