Kodi malo osungirako zida zambiri angakwaniritse zosowa zanu zakusungirako zakunja zakunja?
Njira yowonjezera ya RAID ndiyo njira yowonjezera yowonjezera makompyuta anu omwe akupezeka yosungirako komanso kuwonjezera kuwonjezeka kwa ntchito kapena chitetezo cha deta, kapena onse awiri. Imodzi mwa mafunso ofunika kuti muyankhe pamene mukuyang'ana mawonekedwe osungira akunja a RAID ndi momwe ntchito za RAID zidzakhalire, mu mapulogalamu kapena ma hardware odzipereka.
Nchifukwa chiyani kunja kwa RAID kumakhala?
Tiyeni tiwone bwino, ngati cholinga chanu chikungowonjezera kuchuluka kwa malo omwe mukuyendetsa galimoto, mungapeze njira imodzi yopita kunja ingakhale njira yosakwera mtengo. Njira imodzi yokha yopititsira galimoto ndi yodalirika kwambiri; Ikhoza kugwiritsidwa ntchito pa malo osungirako, monga kuyendetsa galimoto, kapena kukhazikitsa njira zina zosinthira.
Malo opangira RAID, kumbali inayo, adzapangidwira kuti azigwira maulendo angapo ndikupatsa wosuta kuti akonze malo omwe alipo muyambidwe imodzi kapena yambiri ya RAID.
Dziwani zambiri mu nkhaniyi: Kodi RAID ndi chiyani?
Makina a RAID angakonzedwe kuti apereke machitidwe apamwamba kusiyana ndi omwe amapezeka kuchokera ku makina oyendetsa, angaperekenso deta redundancy, kuonetsetsa kuti deta yanu ilipo ngakhale ngati galimoto ikulephera . Mapulogalamu a RAID angakonzedwenso kuntchito komanso chitetezo cha data.
Software kapena Hardware Based RAID Controller
Mtima wa RAID ndi woyang'anira, womwe umapatsa lamulo logawira deta kupita ndi kuchokera ku magalimoto omwe amapanga RAID. Olamulira a RAID akhoza kukhala a hardware pogwiritsa ntchito chip chipangizo cholowera ku RAID, kapena mapulogalamu, pogwiritsira ntchito mphamvu yamakina a kompyuta yanu kuti muwone momwe mawerengedwe amawerengedwera kapena kulembedwa kumalo ozungulira.
Nzeru zambiri zakhala kuti olamulira omwe amagwiritsidwa ntchito pa hardware ali ndi mwayi wopambana, pokhala owerengera oyenerera kuti apange deta kupita ndi kuchoka ku ma drive mu RAID popanda kuika chikhomo cha ntchito. Mapulogalamu apakompyuta kawirikawiri anali otsika mtengo ndipo amakhoza kuchita mokwanira maulendo atatu odziwika bwino a RAID, RAID 0 (Striped for speed) , RAID 1 (Dongosolo lachidule la redundancy) , ndi RAID 10 (Zojambula Zojambula Zowonongeka) . Koma zinkakhala ndi zovuta zogwira ntchito ndi magulu ovuta a RAID.
Maulendo apamwamba a RAID monga RAID 3 ndi RAID 5 omwe amateteza deta pogwiritsa ntchito ziwerengero zovuta kuti apange deta ya data yomwe inalembedwa pambali pamtundu wa deta yomwe inalipo nthawi ina yomwe inkawoneka kuti yaying'ono kwambiri pa machitidwe opangidwa ndi mapulogalamu ndipo inachepetsa Mawindo a ntchito kusiyana ndi omwe amawoneka ndi olamulira a RAID opangidwa ndi hardware.
Komabe, zojambula zamakono zamakono zimagwiritsidwa ntchito pogwiritsa ntchito mapulogalamu ambiri, komanso njira zamakono zamakono zomwe zimagwiritsira ntchito njira zamakono zowonongeka zakhala zowonongeka kwambiri ndi chiwongoladzanja cha machitidwe a RAID, makadi a RAID oposa 0, 1, 3 , 5, ndi 10.
Zogwiritsa ntchito pa-Software
Mapulogalamu a RAID omwe amagwiritsa ntchito maofesi othandizira ali ndi zizindikiro zotsatirazi:
- Mtengo wotsika: Chifukwa chipinda cha RAID chingagwiritse ntchito chipsets chipangizo, mawonekedwe ndi kupanga mafakitale amakhala pansi kwa RAID mkati. Mapulogalamu a pulogalamu amatha kukhala ochepa kwambiri, chifukwa machitidwe ambiri opangira ntchito akuphatikizapo kuthandizira kumbuyo ma level RAID nthawi zambiri 0, 1, 10. Ngati mukufuna RAID 3, kapena 5, pali mapulogalamu owonjezera omwe angatenge kusamalira zosowa zanu.
- Zosagwirizana: Zogwiritsa ntchito ma-RAID opangidwa ndi mapulogalamu amalola kuti kusintha kwakukulu kwambiri pakukonzekera momwe galimoto iliyonse mkati mwake idzagwiritsire ntchito. Muzitsulo zinayi zoyendetsa galimoto; Mutha kukhala ndi magalimoto atatu omwe amaikidwa ngati mizere yopangira machitidwe, ndi 1 lalikulu galimoto kuti abweze. Mukhozanso kukhazikitsa magalimoto anayi ngati magulu awiri odziimira, makina oyimitsa mavidiyo, ndi kusungidwa kwa makina osiyanasiyana a multimedia. Mfundo yaikulu ndi yakuti momwe magalimoto oyendetsera ntchitoyo amagwiritsiridwa ntchito ndi kwathunthu.
- Kuchita: Mapulogalamu okhudzana ndi RAID omwe amagwiritsidwa ntchito pazitsulo zamagetsi kapena zojambulazo sizingatheke kulandira chilango cha ntchito . Ngakhale kuti chiwerengero cha magalimoto omwe amagwiritsidwa ntchito pazowonjezera, kapena magulu ovuta a RAID amagwiritsidwa ntchito, mapulogalamu a RAID opangidwa ndi mapulogalamu angayambe kukhudza momwe ntchito ya RAID ikugwiritsidwira ntchito, komanso ntchito yonse ya kompyuta.
- Kutsogolo: RAID-Based-RAID imagwiritsa ntchito makina a CPU imodzi kapena angapo , komanso RAM yomwe ingakhudze njira zina zomwe zimagwiritsidwa ntchito pa kompyuta yanu. Zomwe zimakhudzidwa zimachokera pa msinkhu wa RAID wogwiritsidwa ntchito, ndi chiwerengero cha ma drive omwe amapanga RAID.
- Bootable: Ichi ndi chosakanikirana, mapulogalamu ena a RAID amagwira bwino ntchito polemba zinthu kuchokera ku RAID, ndipo ena ali ndi vuto. Ngati ndondomeko zanu zikuphatikizapo kuchotsa zinthu kuchokera ku RAID muzitsimikizira kuti pulogalamu ya RAID yomwe mukukonzekera kuti mugwiritse ntchito ikuthandizira.
Zida Zogwiritsa Ntchito Zida
Zothandizira RAID zomwe zimagwiritsa ntchito woyang'anira RAID zogwiritsa ntchito hardware ziri ndi zizindikiro zotsatirazi:
- Ndondomeko: Zokonza zipangizo zamakono zogwiritsa ntchito zipangizo zamakono zidzakhala ndi mtengo wapatali poyerekeza ndi malo otsekemera ambiri popanda chithandizo cha RAID chomwe chinamangidwa. Komabe, kusiyana kwa mtengo kumakhala kochepa. Zida za pulasitiki zomwe zimangogwirizira zitsulo zokhazikika, zojambula kapena zoyendetsa zokhazokha zimakhala ndi mtengo wapatali kwambiri, pomwe olamulira a RAID omwe amagwiritsa ntchito hardware omwe amathandiza miyeso yowonjezera yowonjezera ndipo ma drive ena m'kati mwake akhoza kukhala ndi ndalama zambiri zowonjezera.
- Zomwe zilipo: Machitidwe a RAID-based RAID amawoneka ngati osakaniza disk. Izi zimathandiza kuti njira ya RAID ikhale yowonekera ku kompyuta yomwe ikugwirizana nayo. Mapulogalamu apamwamba ndi maofesi a RAID omwe amachokera pa kompyuta amatha kutengeka mosavuta pakati pa makompyuta ndi machitidwe opangira.
- Zochita: Ngakhale kuti RAID ndi mapulogalamu ndi ma hardware angakhale ndi ziwerengero zofanana zogwirira ntchito za mizere yoyamba ndi mizere, pamene mutasunthira ku mazenera ochulukirapo, machitidwe opangidwa ndi hardware amatha kusokoneza maofesi awo opangidwa ndi mapulogalamu. Kuchita bwinoku sikungokhala kokha kulemba ndi kuwerenga deta komanso kumawonetsa pamene deta yomwe ikuwonetsedwa ikuyenera kumangidwanso chifukwa cholephera kuyendetsa galimoto. Zida zamakono zogwiritsa ntchito RAID zimapanga ntchito yomangidwanso mofulumira kwambiri.
- Kutsogolo: Zitseko za RAID zosagwiritsa ntchito zakunja siziyenera kutulutsa zotsatira pa purosesa kapena pamwamba pa RAM pamakompyuta okonda.
- Zowonongeka: Nthawi zambiri, machitidwe a RAID opangidwa ndi hardware angagwiritsidwe ntchito monga dongosolo lanu la boot linapangitsani kugwirizana kwa kompyuta yanu pogwiritsa ntchito chiwongolero kuti machitidwe opatsirana amathandizira kuchotsa. Mawindo a USB 3 ndi Mabingu ayenera kukhala otsegulidwa koma yang'anani ndi opaleshoni ndi makina opanga kompyuta kuti atsimikizire.
Zotsatira za RAID
- RAID yothandizira imagwiritsa ntchito thumbs pamene mphamvu ikusunga mtengo ndipo ntchito yako RAID idzangokhala pa RAID 0 (mizere), Raid 1 (yosungidwa), kapena RAID 10 (Zojambula Zojambula Zojambula) . Mtundu wa RAID uwu ndi chisankho chabwino kwa ogwiritsa ntchito kunyumba omwe angagwiritse ntchito RAID dongosolo ndi kompyuta imodzi.
- Zogwiritsa ntchito zipangizo zamakono ndizosankha pazitsulo zazikulu zoopsa za RAID, monga kugwiritsidwa ntchito pa RAID 3 kapena RAID 5 zomwe zimaphatikizapo ziphuphu zamagulu zomwe zimapangidwira ndikuziyerekezera mu nthawi yeniyeni monga momwe deta imatumizidwa ndi kuchokera ku RAID. Zida zamakono zogwiritsa ntchito RAID ndizonso zabwino kwambiri pa machitidwe akuluakulu a RAID 0 ndi RAID 1 pamene mukufuna kuti RAID ikhale yokhazikika pa kompyuta yanu, ndikukupatsani mphamvu yothetsera dongosolo pakati pa makompyuta ambiri.
