Iqoqo liyisixhobo sendawo yonke yokwandisa umveliso

Imeko enomdla iye yaveliswa kwikharityhulam ye-IT yanamhlanje. Amaseva anamandla, axabisa amaxesha amaninzi amaxabiso angaphezu kwama-computer aqhelekileyo, angabonakali ngokuphindwe kabini kwimizuzu emithathu kuphela. Umbuzo kukuba, kutheni ukhokhe ngakumbi xa ungasebenzisa iteknoloji ephezulu kwaye udibanise iikhompyutheni ezahlukeneyo ezingafaniyo zibe sisiqendu. Oku kuya kukunceda ugcine imali kwaye ungaphumeleli ngamandla ofunekayo kwiinjongo ezithile. Ukongeza, kwibhonasi ufumana inkqubo ephindiweyo. Iqoqo le-failover liyakukuvumela ukuba wakhe inkqubo ephezulu.

Ubugcisa beCluster busetyenziswa kakhulu kwiindawo ezahlukeneyo zomsebenzi, apho kuphela ukusebenzisa iikhomputha ezinamandla. Iqela liqela elithile (amashumi, amakhulu, amawaka) eikhompyutheni ezingafaniyo, ezidibeneyo ngendlela enokubaluleka ekusebenzeni izibalo. Ngelo xesha, nangona inani elikhulu lezakhi, kubonakala liphela liphela.

Esinye sezizathu eziphambili zokuvela kwetheknoloji yokudibanisa iikhomputha kwiqela kukubizwa ngokubanzi kwe-intanethi kunye namazinga ayo okukhula kwendawo. Ukukhula kwinani leenkcukacha ezithunyelwayo kufuneke ukuba kudingeke ukuba kwenziwe iinkqubo ezinamandla zokucwangcisa. Kodwa i-hardware, kuyo yonke i-technology ye-technology, ayinakuhlala ihlangabezana nemisebenzi eyabelwe yona. Ngoko ke, kwakukho isidingo sokudibanisa le nxalenye yehardware ekusebenzeni imisebenzi yehlabathi. Ukongezelela, ukuthembeka okuphezulu ukuba iqela lamaseva linikeza uncedo kwiinkampani ezinkulu ezigcina ubuninzi beenkcukacha.

Ngendawo yabo yendawo, amaqela ahlukeneyo aphakathi kwaye aphantsi. Eyokuqala, njengomgaqo, ikhona ngaphakathi kwelinye igumbi, okokugqibela, ngokuchaseneyo, kunokusasazeka kwiindawo ezikude. Ukwandisa, le teknoloji isetyenziselwa kwintsimi yekhompyutheni, apho kusebenza khona i-hardware ephezulu yokusebenza.

Umgangatho ophezulu wezinto ezixhuma, amandla amakhulu aphezulu kwisiteshini ngasinye kwisantya esikhulu sokuqhutyelwa kolwazi oluhambayo - yonke into edibeneyo kwiqela iyisisombululo esikhulu esivumela ukuba kwenziwe imisebenzi ecacileyo nayiphi na inkathazo: ukususela kwimimiselo yeentlekele ekulawuleni ukushayisana kwama-athomu ngokukhawuleza.

Isigaba esilandelayo ekuphuhlisweni kobuchwepheshe beekhnoloji sinokuba yinkqubo yokusebenzisa i-matrix. Isiseko salo sisebakala lokuba izibonelelo ezingenamsebenzi kwazo zonke iikhomputha kunye nezixhobo ezenza inethwekhi zisetyenziselwa ukuxazulula iingxaki zehlabathi. Oku kuphunyezwe ngokucwangcisa ngokufanayo ulwazi.

Iinkqubo zeCluster zinemivuzo eninzi ngaphezu kwezakhiwo eziqhelekileyo ze-monoblock. Zivelisa ngakumbi, zinamandla kwaye zinokwethenjelwa. Ngokusetyenziswa kwetheknoloji yeqoqo, kunokwenzeka ukuphumeza isisombululo malunga nantoni nayiphi na imisebenzi ebekiwe, kungakhathaliseki ukuba yinkalo yobunzima.
