Ukusetyenziswa nini iSoftware RAID

I-Software RAID ilungile kwiiseva zasekhaya, iiofisi ezincinci, kunye nabani na ojonga ukhuseleko lwedatha olungabizi kakhulu. Isebenzisa izixhobo zesistim yakho ukuze iguquguquke kunye nokugcinwa okunokwehla. Oku ngaphandle kwesidingo sabalawuli be-RAID ababizayo.

Kwiiseva zasekhaya, iRAID yesoftware yonyusa ukhuseleko lwedatha kunye nesantya. Iyafikeleleka, iyenza igqibelele kwabo bakwibhajethi eqinileyo. Kwaye, kulula ukulawula kunye nokuseta amanqanaba ahlukeneyo e-RAID inkxaso ngesoftware.

Iiofisi ezincinci zikwaxhamla kwisoftware yeRAID. Inceda inkqubo scalability kunye nokusebenza kakuhle. Unokongeza iidrive ezintsha ngokulula, ukhulise ugcino lwakho njengoko kufuneka. Oku kwenza kube lula ukunyenyisa ugcino lwakho ukuze luhambelane neemfuno zeshishini lakho.

Amanqanaba athile e-RAID afana ne-RAID 0, i-RAID 1, kunye ne-RAID 5 isebenza kakuhle kunye ne-software ye-RAID. Inqanaba ngalinye linenzuzo yalo:

IRAID 0: Inkulu ekusebenzeni okuphezulu ngaphandle kokugcinwa kwedatha.

IRAID 1: Ilungele abo bafuna ukukhuselwa kwedatha kunye nokuphindaphinda.

IRAID 5: Inikezela ngolungelelwaniso lokusebenza, ukungafuneki, kunye nokusebenza kakuhle kogcino.

I-Software RAID isebenza kakuhle kunye neetekhnoloji ze-virtualization. Oku kuyenza ibe yinxalenye ephambili yokuseta i-IT yanamhlanje. Inceda ukudala inkqubo yokugcina eguquguqukayo ehambelana neemfuno eziguqukayo.

Isishwankathelo, i-RAID yesofthiwe lukhetho oluhlakaniphile kunye nohlahlo lwabiwo-mali lokulawula idatha. Ifanelekile kwizicelo ezahlukeneyo kunye neemeko.

Ukusetyenziswa nini i-Hardware RAID

Kwiimeko ezifuna ukugcinwa kokufumaneka okuphezulu kunye nokusebenza kwinqanaba leshishini, i-Hardware RAID lolona khetho lungcono. Oku kuyinyani ngakumbi kumashishini aphatha idatha eninzi. Apha, ukuthembeka kunye nesantya zingundoqo.

Ukukhetha i-RAID ye-hardware kulungile kuba isebenza kakuhle ngokusebenza ngokukhawuleza kwe-SSD, ii-NVMe drives, i-SATA, kunye ne-SAS drives. Ibonelela ngokuphuma okuphezulu kunye ne-latency ephantsi, ebalulekileyo kwiimfuno zamashishini amakhulu.

"Isakhono se-Hardware RAID yokuphucula kakhulu iidrive ze-NVMe kunye nokusebenza kwe-SSD akunakuthelekiswa.

Nangona i-RAID ye-hardware ixabisa ngaphezulu, ifanelekile. Iqinisekisa ukuba inkqubo yakho isebenza kakuhle kwaye idatha ihlala ikhuselekile. Kuseto olukhulu, oku kuthetha ukonga imali kunye nokunyusa imveliso.

Izisombululo zeHybrid RAID

I-Hybrid RAID yindlela entsha yokulawula idatha edibanisa i-software kunye ne-hardware ye-RAID iinkqubo. Inika ukuguquguquka kwesoftware ye-RAID kunye nesantya se-hardware RAID. Lo mxube wenza kube lukhetho olulungileyo lokulinganisa iindleko, ukukhula, kunye nokusebenza kakuhle.

I-Hybrid RAID ilungile kuba iyayazi indlela yokusebenzisa indawo yokugcina kakuhle. Isasaza idatha kumanqanaba ahlukeneyo okugcina ukwenza uninzi lwento onayo. Ukusebenzisa itekhnoloji ye-virtualization yenza kube ngcono ngakumbi ngokufihla imida ye-hardware, ekhokelela ekusebenzeni okungcono kunye nokuzimela kwe-hardware.

Izakhono zokulawula i-RAID kwiinkqubo ze-RAID ezixubileyo ziphezulu. Banokutshintsha indlela idatha elawulwa ngayo kwi-fly ukuhlangabezana nemfuno. Oku kugcina ukusebenza kuzinzile kwaye kuthembekile, nto leyo engundoqo kwimisebenzi emikhulu yedatha. Kwaye, yenza i-hardware endala ihlale ixesha elide, igcina imali ekuhambeni kwexesha.

Nalu ujongo olukhawulezileyo kwindlela i-RAID exutywe ngayo idibanisa eyona nto ibalaseleyo yehlabathi:

IiNgcebiso zokuSebenza ngokuPhucula iRAID

Ukulungiswa kokusebenza kwe-RAID ngundoqo kulawulo olululo lwedatha kunye nokuthembeka kwenkqubo. Ngokujolisa kwiinkqubo eziphambili, unokwenza ukuseta kwakho kwe-RAID kusebenze ngakumbi.

Ukubhala i-caching yindlela ephezulu yokunyusa ukusebenza kwe-RAID. Igcina idatha kwi-cache ngaphambi kokuyibhala kwidiski. Oku kunciphisa i-latency kwaye kwandisa i-throughput. Kodwa, kubalulekile ukucinga malunga nemfezeko yedatha, njengoko idatha egciniweyo inokulahleka ngexesha lokusilela kwamandla. Ukusebenzisa i-cache yokubhala exhaswa yibhetri okanye izixhobo zombane ezingaphazamisekiyo (UPS) zinganceda ukunqanda lo mngcipheko.

Esinye isicwangciso esibalulekileyo kukubeka iliso kwi-SMART. Le teknoloji ihlola impilo yeediski zakho ngokuqhubekayo. Ikuvumela ukuba ulungise imiba ngaphambi kokuba ibe mandundu. Ukujongwa rhoqo kwe-SMART kunokwenza imisebenzi ye-disk I/O ibe lula.

Ukuphucula i-I/O yediski kubalulekile ekusebenzeni okuphezulu. Ubuchwephesha obufana nokulinganisa umthwalo kunye nokusebenzisa iidiski ezinesantya esiphezulu kunokuphucula kakhulu idisk ye-I/O yokwenza.

Ukuphucula isantya sokwakha i-RAID nako kubalulekile. Xa i-drive ingaphumeleli, inkqubo yokwakhiwa kwakhona inokucotha kwaye irhafise. Ukuseta izinto eziphambili zokwakhiwa kwakhona, ukusebenzisa iidrive ezikhawulezayo, kunye nokugcinwa rhoqo kunokunceda ukukhawulezisa ukwakhiwa kwakhona kwe-RAID. Oku kunciphisa ixesha lokuphumla kunye nokuphucula ukufumaneka kwenkqubo.

Ngaphezu koko, ukulawula i-cache yomlawuli we-RAID kubalulekile. Ukuyimisela ukubeka phambili imisebenzi yokufunda okanye ukubhala ngokusekelwe kwiimfuno zomthwalo womsebenzi ngundoqo. Obu buchule buqinisekisa ukuseta kwe-RAID elungiselelwe kakuhle elinganisa isantya, ukuthembeka, kunye nokuthembeka kwedatha.
