Qonda iimpawu zobugcisa zeenkqubo ze-has

Ukufumaneka okuphezulu (i-HA)Kubaluleke kakhulu ekuqinisekiseni ukusebenza okuqhubekayo kwezicelo ezibalulekileyo kunye neenkonzo. Ezi nkqubo zenzelwe ukunciphisa ixesha lokuphumla kwaye kuqinisekiswe ukusebenza ngaphandle kwegama, kubenza babe yinxalenye yendlela ebalulekileyo yezibonelelo zangoku. Kwezi bhlog, siyakusebenzisa kwiimpawu zobugcisa zeenkqubo ze-Hissis kwaye ziphonononge ukuba ziphucula njani ukuthembeka nokuhluma.

1. Ukuhlawulwa kwakhona: Enye yezinto eziphambili ze-hasty ze-Hastem ye-Hassion iyafumaneka. Oku kubandakanya ukuphindaphinda izinto eziphambili ezinjengamaeseva, ukugcinwa kunye nezixhobo zenethiwekhi ukuqinisekisa ukuba icandelo elinye liyasilela, kukho i-backup elungele ukuthatha ngaphezulu. Ukuhlawulwa kwakhona kubalulekile ukunciphisa amanqaku athile okusilela nokuqinisekisa ukusebenza okuqhubekayo kwimeko yezixhobo zekhompyuter okanye kwimiba yesoftware.

I-2. Inkqubo yeFailover: Iinkqubo ze-HI zixhotyiswe ngenkqubo ye-Filogrism enokuthi itshintshele ngokuzenzekelayo kumacandelo asegcinayo okanye iinkqubo kwimeko yokungaphumeleli. Oku kunokubandakanya ukuphinda uhlengahlengiswa ngokuzenzekelayo kwendlela yenethiwekhi, ukutshintshela kwiiseva ezingafunekiyo okanye i-failover kwizixhobo zokugcina i-backup. Iindlela zeFilover zenzelwe ukunciphisa ukuphazamiseka kwenkonzo kwaye kuqinisekiswe ukuqhubeka kwentliziyo.

3. Ukulayisha ukulinganisa: iinkqubo zihlala zisebenzisa iindlela zokulayisha ukuhambisa umthwalo kuzo zonke iiseva ezininzi okanye izixhobo. Oku kunceda ekwenzeni ukusetyenziswa kwezixhobo kwaye kuthintele naliphi na icandelo elinye ekubeni likhathazekile. Ngokuhambisa ngokulinganayo, iinkqubo ze-has zinokugcina intsebenzo kunye nokufumaneka kwanaxesha lokusetyenziswa kwenqanaba.

4. Ukubeka iliso kunye nokwazisa: Ukubeka iliso ngempumelelo kunye nokubekwa kwengqondo ngempumelelo kubalulekile kwiinkqubo ze-H. Ezi nkqubo ziqhubekayo zibeka iliso kwimpilo kunye nokusebenza kwamacandelo kunye neenkonzo, abalawuli abakwaziyo nayiphi na imiba enokubakho okanye i-anomalies. Ukubek'esweni okusebenzayo kuqaphela iingxaki kwangoko, kuvumele ungenelelo ngexesha elifanelekileyo ukuthintela ixesha lokuphumla okanye kwinkonzo.

I-5. Ukuphindaphinda kwedatha: Ukuphinda kwenziwe idatha yinxalenye yesiseko yeenkqubo, ukuqinisekisa ukuba idatha ebalulekileyo iphindaphindwa kuyo yonke izixhobo okanye iindawo. Oku akunikezeli nje ukhuselo lwedatha kwimeko yesifo se-Hardware, kodwa ikwanceda i-seam engenamthungo kwiinkqubo ezingafunekiyo zingenayo ilahleko yedatha.

I-6. Ukubuyiselwa ngokuzenzekelayo: Iinkqubo ze-ha zenzelwe ukuba zenze inkqubo yokubuyisela kwimeko yesiqhelo. Oku kunokubandakanya ukuthengwa ngokuzenzekelayo, ukubuyiswa kwenkonzo kunye nokuthintelwa kwakhona kwezinto ezingasebenziyo emva kokusonjululwa ingxaki. Inkqubo yokubuyisela kwakhona ezenzekelayo inceda ukunciphisa ifuthe lokusilela kunye nokunciphisa isidingo sokungenelela kwesandla.

I-7. Ukungabinamali: Ukunganyamezeleka kwenye into ebalulekileyo yezobugcisa ye-HA System. Ezi nkqubo zenzelwe ukukhululeka ngaphandle kwendawo yokugcina imithwalo yokukhula kunye neemfuno zezixhobo. Nokuba wongeza iiseva ezongezelelweyo, ukugcinwa, okanye umthamo wenethiwekhi, iinkqubo zinokuziqhelanisa nokutshintsha kweemfuno ngaphandle kokulalanisa.

Ngamafutshane, ubuchwepheshaIimpawu zeenkqubo ze-hasDlala indima ebalulekileyo ekuqinisekiseni ukuthembeka, ukomelela, kunye nokusebenza okuqhubekayo kwezicelo ezibalulekileyo kunye neenkonzo. Ngokufaka izinto ezingafunekiyo, kwiindlela zokugcina izilwanyana, ukubeka iliso, ukuphindaphinda, ukubuyiswa kwedatha, kunye nokusebenza, iinkqubo zokusebenza, zibenza babe nako ukubakho kwimeko yedijithali yanamhlanje. Ukuqonda ezi mpawu zobugcisa kubalulekile kwimibutho ejonge ukufumana isisombululo esinamandla ha Ukuxhasa imisebenzi yabo yamashishini afanelekileyo.
