2.3 Redundant Drive History Modules Txheej txheem cej luam Keeb Kwm Modules muaj peev xwm ntawm redundant disk drive configurations. Qhov ntxiv redundant Winchester disk drive (s) nyob rau hauv ib tug thib ob Winchester Drive Module uas yog stacked saum lub thawj Winchester Drive Module thiab yog lub cev zoo ib yam li WREN III, 210 MB, 445 MB, 875 MB, los yog 1.8 GB Dual Drive configuration uas yog illustrated nyob rau hauv daim duab 2-5 thiab 1. Dab tsi yog redundancy? Lo lus "redundancy" yog siv los piav qhia txog kev rov ua dua WREN III, 210 MB, 445 MB, 875 MB, lossis 1.8 GB drives, tsis yog cov khoom siv hluav taws xob rov ua dua, uas yog cov ntaub ntawv nrog lwm cov LCN modules. Txawm hais tias hard drives muaj kev ntseeg siab heev, qhov kev puas tsuaj loj uas cov ntaub ntawv ploj thaum lub sij hawm tsis ua hauj lwm qhia tau hais tias muaj peev xwm xav tau cov ntaub ntawv rov qab thaum lub sijhawm ua haujlwm. Redundancy tsav synchronization Nyob rau hauv ib qho redundant configuration, software ua tau zoo sau rau ib WREN III, 210 MB, 445 MB, 875 MB. los yog 1.8 GB tsav, tom qab ntawd ua qhov zoo ib yam sau rau nws tus khub rov ua dua los muab ob lub drives nrog cov ntaub ntawv zoo ib yam. Cov txheej txheem hu ua "cov ntaub ntawv synchronization." Yog hais tias lub hard drive "crash" tshwm sim, software ignores lub tsav tsis ua hauj lwm thiab tseem ua hauj lwm nrog nws tus khub zoo. Cov khoom siv rov ua dua tshiab yog tsim los kom tus kws kho mob tuaj yeem tshem tawm cov tsav tsis ua haujlwm yam tsis muaj kev cuam tshuam lossis tshem tawm lub zog los ntawm nws tus khub zoo. Tom qab lub tsav tau hloov lawm, tus kws tshaj lij ua haujlwm "synchronization" uas theej cov ntaub ntawv rau tus tsav tshiab thiab rov ua haujlwm dua. Tsav tsheb nrog kev rov ua dua Redundancy yog tsim los rau hauv cov khoom siv kho vajtse kom tus kws tshaj lij kev pabcuam tuaj yeem tshem tawm Winchester Drive Tray uas muaj cov tsav tsis ua haujlwm yam tsis muaj kev cuam tshuam lossis tshem tawm lub zog los ntawm nws tus khub "zoo" txuas rau lwm lub tais. Tom qab lub tsav puas tau raug kho lossis hloov, lub tais rov qab, thiab tus kws tshaj lij ua cov txheej txheem "cov ntaub ntawv synchronization" uas luam cov ntaub ntawv khaws cia rau ntawm "zoo" (thawj) tsav mus rau qhov kho lossis hloov tsav. Rov qab ua haujlwm rov qab yog tom qab ntawd. Txhawm rau rov qab los ntawm qhov tsis tuaj yeem rov qab tau cov ntaub ntawv yuam kev ntawm lub tsav, cov haujlwm tsis zoo tuaj yeem pib lossis muab xa mus rau Cov Ntaub Ntawv Tsis Zoo thaum lub sijhawm ua haujlwm txuas ntxiv siv lub "zoo" tsav.
