Chosavomerezeka Kupirira Mwamsanga Werengani Nthawi
RAID 5 ndi msampha wa RAID wokonzedwa kuti uwonjezere kufulumira kwa ma diski ndikulemba. RAID 5 ndi ofanana ndi RAID 3 chifukwa imagwiritsira ntchito chidutswa chothandizira kuti zitsimikizire deta. Komabe, mosiyana ndi RAID 3, yomwe imagwiritsira ntchito diski yopatulira kusunga umulungu, RAID 5 imagawira mgwirizano ku magalimoto onse m'gulu.
RAID 5 imapereka kuyendetsa galimoto kulekerera, kulola kuti galimoto iliyonse muyeso ikhale yolephera popanda kutaya deta iliyonse. Pamene galimoto ikulephera, gulu la RAID 5 lingathe kugwiritsidwa ntchito kuwerenga kapena kulemba deta. Dalaivala lolephera litasinthidwa, gulu la RAID 5 lingalowetse njira yowonzetsera deta, pamene deta ya deta yomwe ikugwiritsidwa ntchito ikugwiritsidwa ntchito kumanganso deta yosasoweka pa galimoto yongoyambika kumene.
Kuwerengera RAID 5 Kukula Kwambiri
Zogwiritsa ntchito 5 zogwiritsira ntchito zimagwiritsa ntchito zofanana ndi galimoto yosungirako chiyanjano, zomwe zikutanthauza kuti kukula kwake kwakukulu kungathe kuwerengedwa pogwiritsa ntchito njira yotsatirayi:
S = d * (n - 1)
The "d" ndi disk yaing'ono kwambiri pa disk, ndipo "n" ndi chiwerengero cha disks zomwe zimapangidwa.
Gwiritsani ntchito bwino RAID 5
RAID 5 ndi chisankho chabwino chosungira mafayilo a multimedia. Kuwunikira kwake kumatha kukhala kotsika kwambiri, pamene liwiro la kulemba limapita pang'onopang'ono, chifukwa cha kufunikira kuwerengera ndi kugawira mgwirizano. RAID 5 imaposa kusunga mafayilo akuluakulu, kumene deta imawerengedwera sequentially. Maofesi ang'onoang'ono, omwe amapezeka mwachisawawa amatha kuwerenga bwinobwino, ndipo kulembera ntchito kungakhale kosauka chifukwa cha kufunika kokonzanso ndi kulembanso chiwerengero cha chiwerengero cha ntchito iliyonse yolembera.
Ngakhale RAID 5 ikhoza kuyendetsedwa ndi kukula kwa ma disk, zomwe sizinayesedwe njira yofunira kuyambira kukula kwa RAID 5 kudzafotokozedwa ndi disk yaing'ono kwambiri muyikidwa (onani ndondomeko pamwambapa).
Chifukwa cha kufunika kokhala ndi chiwerengero cha chiwerengero ndi kugawira chiwerengerocho, RAID 5 ndi yabwino kwambiri poyikidwa mu zipangizo za RAID zomwe zimagwiritsidwa ntchito pa hardware. Pulogalamu ya Disk Utility yomwe ikuphatikizidwa ndi OS X sichikuthandizira kupanga mapulogalamu a RAID 5, komabe SoftRAID, wochokera ku kampani yachitatu SoftRAID, Inc., angagwiritsidwe ntchito ngati njira yothetsera maofesi ikufunika.
