1. Intangiriro kuri RAID
2. RAIDs isanzwe irimo 0, 1, 5, na 10. Reka tuganire kubyiza byabo byihariye
3. Ni izihe nyungu za RAID kuri mudasobwa zinganda?

1. Intangiriro kuri RAID

RAID nayo yitwa Redundant Array ya Disiki Yigenga. Nuburyo bwo kubika bugizwe na disiki nyinshi zikomeye. Urashobora kandi kubitekereza nkibihuza byuruhererekane, kubihuza hamwe. Itezimbere amakuru menshi kandi iboneka mugukwirakwiza amakuru kuri disiki nyinshi zikomeye.

RAID irashobora gutanga imirimo ikurikira:

1. Huza imyanya ibiri cyangwa myinshi ikomeye ya disiki muri rusange kugirango wongere igipimo cyo gusoma cya disiki.

2. Kunoza kwihanganira amakosa; kwihanganira amakosa bivuze ko niba amakuru yangiritse, urashobora kugarura amakuru yangiritse uramutse ushyizeho RAID (usibye RAID0)

Urwego rusanzwe rwa RAID:

RAID igabanyijemo RAID0, RAID1, RAID2, RAID3, RAID4, RAID5, RAID6. Izi nzego 7 ni RAID isanzwe, nayo izwi ninganda. Urwego rusanzwe nirwo shingiro rwibanze rwa RAID rwashyizweho, ukoresheje tekinoroji nka data striping cyangwa mirroring. Izi nzego zisanzwe za RAID zirashobora guhuzwa, kandi RAID ihuriweho izaba ifite imikorere ihanitse, umutekano, no kwizerwa.

2. RAIDs isanzwe irimo 0, 1, 5, na 10. Reka tuganire kubyiza byabo byihariye

1. RAID0 nimwe yoroshye ibika amakuru kuri disiki nyinshi zinyuze kumurongo. Ntishobora gutanga uburyo ubwo aribwo bwose bwo kugabanya, bivuze ko niba amakuru yacu yangiritse, RAID0 ntishobora kugarurwa. Ariko, irashobora gutanga ibyiza nko gusoma cyane no kwandika imikorere no gukoresha ububiko bwinshi. RAID0 muri rusange ikwiranye na software zimwe zifite ibisabwa byiza byo gukora ariko ntibikaze cyane mubijyanye numutekano wamakuru.

2. RAID1 yitwa indorerwamo. Muri make, disiki ebyiri zikomeye zateguwe, ariko urabona gusa ubushobozi bwa disiki imwe ikomeye muri sisitemu ya mudasobwa. Ubundi disiki ikomeye ikoreshwa mukurinda amakuru. Iyo disiki ikora ikora yananiwe, disiki yindorerwamo izasoma amakuru kandi yuzuze icyuho.

RAID1 ni ikinyuranyo cya RAID0. Nukwongera umutekano wamakuru ukoresheje indorerwamo ya disiki ikomeye, kugirango ugere ku byiza byumutekano kandi byoroshye. Ifite igipimo cyuzuye cyo kwihanganira amakosa, ariko ikiguzi ni kinini. RAID1 ikoreshwa mubisabwa hamwe nibisomwa bikurikiranye gusoma no kwandika imikorere no kurinda amakuru, nko kurinda amakuru yibanga-urwego rwibanga.

3. RAID5 ni urwego rusanzwe. Irashobora kuzirikana ibyiza byo kubika no kubika amakuru. Birashobora kumvikana nkubwumvikane hagati ya 0 na 1, kandi nigisubizo hamwe nibikorwa byiza muri rusange. RAID5 irashobora guhura cyane cyane mububiko bukenewe, kandi ibigo byinshi bikoresha RAID5.

4. RAID10 ikomatanya ibyiza bya RAID1 na RAID0. Irabanza ikoresha disiki ebyiri zikomeye kugirango ikore ishusho yindorerwamo, hanyuma ikayihindura imbere. Ibyatanzwe na RAID1 byanditswe kuri disiki ebyiri zikomeye icyarimwe. Niba disiki imwe ikomeye yangiritse, indi disiki ikomeye irashobora gukomeza gukora, ikemeza imikorere mugihe umutekano wamakuru. Ariko, igipimo cyo gukoresha disiki ya RAID10 ni 50% gusa.

3.Ni izihe nyungu za RAID kuri mudasobwa zinganda?

1. Kongera igipimo cyo kohereza: Ukoresheje disiki nyinshi icyarimwe, tekinoroji ya RAID irashobora kongera cyane igipimo cyo kohereza amakuru ya sisitemu yo kubika. Muburyo bwa RAID, disiki nyinshi za disiki zirashobora kohereza amakuru icyarimwe, zituma gusoma no kwandika byihuta.

2. Niba disiki imwe yananiwe, sisitemu ya RAID irashobora gukoresha amakuru kurindi disiki kugirango igarure amakuru yatakaye, cyangwa igarure muri backup.

3. Kongera ubushobozi bwo kubika: Binyuze mu kwambura ikoranabuhanga, RAID irashobora gukwirakwiza no kubika amakuru kuri disiki nyinshi, bityo bikongerera ubushobozi bwo kubika. Kurugero, nyuma yo gukoresha disiki ebyiri 1TB kugirango ukore uburyo bwa RAID 0, ubushobozi bwa disiki buzahinduka kuri 2TB.

4. Incamake:

Abantu bakeneye gukoresha tekinoroji ya RAID mubusanzwe bakeneye gutunganya amakuru menshi, gukurikirana imikorere ihanitse kandi yizewe, kandi bafite ibisabwa byinshi kumutekano wamakuru.
