2.3 Uhlolojikelele lwamamojula Omlando Wedrayivu Amamojula ayakwazi ukuhlela okungadingekile kwedrayivu yediski. Idrayivu yediski ye-Winchester eyengeziwe engasasebenzi itholakala Kumojula yesibili ye-Winchester Drive estakwe ngaphezu kwe-Winchester Drive Module eyinhloko futhi ifana ngokoqobo ne-WREN III, 210 MB, 445 MB, 875 MB, noma ukulungiselelwa kwe-Dual Drive engu-1.8 GB eboniswe ku-Figure 2-5.1 kanye no-2 Kuyini ukuphelelwa umsebenzi? Igama elithi "redundancy" lisetshenziselwa ukuchaza okungafuneki kwe-WREN III, 210 MB, 445 MB, 875 MB, noma 1.8 GB amadrayivu, hhayi amamojula we-elekthronikhi angasadingeki, okuyisimo esifanayo namanye amamojula e-LCN. Nakuba ama-hard drive athembekile, imvelo eyinhlekelele lapho idatha ilahleka khona ngesikhathi sokwehluleka ibonisa isidingo esingaba khona sokuthi idatha yenziwe ikhophi yasenqolobaneni phakathi nokusebenza okuvamile. Ukuvumelanisa kwedrayivu ye-redundancy Ekucushweni okungadingekile, isofthiwe ibhala ngempumelelo eyodwa ethi WREN III, 210 MB, 445 MB, 875 MB. noma idrayivu engu-1.8 GB, bese ibhala okufanayo kuzakwethu ongasasebenzi ukuze inikeze amadrayivu amabili anezizindalwazi ezifanayo. Inqubo ibizwa ngokuthi "ukuvumelanisa idatha." Uma “ukuphahlazeka” kwe-hard drive kwenzeka, isofthiwe iyiziba idrayivu ehlulekile futhi iyaqhubeka nokusebenza nozakwethu omuhle. Izingxenyekazi zekhompuyutha ezingasasebenzi ziklanywe ngendlela yokuthi uchwepheshe wokulungisa akwazi ukususa idrayivu ehlulekile ngaphandle kokuphazamisa noma ukukhipha amandla kuzakwethu omuhle. Ngemuva kokuthi idrayivu ishintshiwe, uchwepheshe wenza umsebenzi "wokuvumelanisa" okopisha idatha kudrayivu entsha futhi abuyisele ukusebenza okungafuneki. Ukulungiswa kwedrayivu nge-redundancy Redundancy yakhelwe ku-hardware ukuze uchwepheshe wesevisi akwazi ukususa Ithreyi ye-Winchester Drive equkethe idrayivu ehlulekile ngaphandle kokuphazamisa noma ukukhipha amandla kuzakwethu “omuhle” obekwe kwelinye ithreyi. Ngemva kokuba idrayivu enesici isilungisiwe noma ishintshiwe, ithreyi iyafakwa kabusha, futhi uchwepheshe wenza inqubo “yokuvumelanisa idatha” ekopisha idatha egcinwe kudrayivu “enhle” (eyisipele) kudrayivu elungisiwe noma eshintshiwe. Umsebenzi wokuphelelwa umsebenzi ube usubuyiselwa. Ukuze ululame ephutheni ledatha elingalungiseki kudrayivu, imikhakha emibi ingaqalwa noma yabelwe Uhlu Lwedatha Yesici kuyilapho ukusebenza kwesistimu kuqhubeka kusetshenziswa idrayivu “enhle”.
