2.3 Redundant Drive History Modules Overview History Modules amatha kusintha ma disk drive owonjezera. Winchester disk drive(s) yowonjezera yowonjezera ili mu Winchester Drive Module yachiwiri yomwe ili pamwamba pa Winchester Drive Module ndipo imakhala yofanana ndi WREN III, 210 MB, 445 MB, 875 MB, kapena 1.8 GB Dual Drive kasinthidwe kamene kakuwonetsedwa mu Zithunzi 2-5.1 ndi 2-2 Kodi redundancy ndi chiyani? Mawu akuti "redundancy" amagwiritsidwa ntchito pofotokoza za WREN III zosafunikira, 210 MB, 445 MB, 875 MB, kapena 1.8 GB zoyendetsa, osati ma modules amagetsi owonjezera, zomwe zili ndi ma modules ena a LCN. Ngakhale ma hard drive ndi odalirika, tsoka lomwe data limatayika pakalephereka likuwonetsa kufunikira kofunikira kuti deta isungidwe m'malo mwanthawi zonse. Kulunzanitsa kwapang'onopang'ono pakusasinthika, mapulogalamu amalembera bwino WREN III, 210 MB, 445 MB, 875 MB. kapena 1.8 GB drive, ndiye amalembera chimodzimodzi kwa mnzake wosafunikira kuti apereke ma drive awiri okhala ndi nkhokwe zofanana. Njirayi imatchedwa "data synchronization." Ngati "kuwonongeka" kwa hard drive kumachitika, mapulogalamu amanyalanyaza zolephera zomwe zalephera ndipo akupitiliza kugwira ntchito ndi mnzake wabwino. Zida zosagwiritsidwa ntchito zimapangidwira kuti katswiri wokonza zokonza angathe kuchotsa galimoto yomwe yalephera popanda kusokoneza kapena kuchotsa mphamvu kwa mnzake wabwino. Pambuyo poyendetsa galimotoyo, katswiriyo amachita ntchito ya "synchronization" yomwe imakopera deta ku galimoto yatsopano ndikubwezeretsanso ntchito yowonjezera. Kukonzekera kwagalimoto ndi redundancy Redundancy yapangidwa mu hardware kotero kuti katswiri wa ntchito angathe kuchotsa Winchester Drive Tray yomwe ili ndi galimoto yolephera popanda kusokoneza kapena kuchotsa mphamvu kuchokera kwa mnzake "wabwino" woikidwa pa tray ina. Pambuyo pokonza zolakwika kapena kusinthidwa, thireyi imabwezeretsedwanso, ndipo katswiriyo amapanga ndondomeko ya "data synchronization" yomwe imakopera deta yomwe imasungidwa pa "zabwino" (zosunga zobwezeretsera) ku galimoto yokonzedwanso kapena yosinthidwa. Ntchito ya redundancy imabwezeretsedwa. Kuti muyambirenso cholakwika cha data chomwe sichingachitike pagalimoto, magawo oyipa atha kukhazikitsidwa kapena kuperekedwa ku Defect Data List pomwe magwiridwe antchito akupitiliza kugwiritsa ntchito "zabwino" drive.
