isidayiki esikhathazo se-nas

IsiDiki esembeni (Network Attached Storage) sikhombisa umqondo wesicelo sekhombiso elwenziwe ngokwespecifika ukufikelela kudatha noku управления. Lezi zidiki zinhloke ukusebenza ngokuphelele, kunikeza inkxenye yemfanelo kuzindlela zabantu abaningi lapho kubuyiselwa udatha. Izidiki zaseNAS zinezimfuneko eziphambene nezomphathi wokuvikela, izinkinobho zokuhlela amandla, nezinkinobho ezinhle zokulungisa imposo, okwenza yena into engiyokulandelana nokusebenzela kwamasipho noma kwezindawo zokugcina datha zasekhaya. Ngokulinganisa nezidiki ze desktop ezengeziwe, izidiki zaseNAS zenziwe ngokuthulile, zingakwazi ukuxhandlela izidingo zokusebenza ngokuphelele lapho kubuyiselwa ispeedi sokufunda nokubhala. Zifaka phakathi le firmware eseciswe eyenza kube lula ukuthi zilandane nezinhlelo zaseNAS nezinhlelo misa yeRAID, ukuze kube khona ukuthi zilayishwe futhi zenze ngokushesha. Lezi zidiki kahle kunezimali zokugcina apho kusuka ku2TB ukuya ku20TB, zixhomeke izidingo zokugcina datha ezinzile zabasebenzisi. Itheknoloji emuva lezi zidiki ifaka phakathi izinkinobho zokucacheza, izinhlelo zokushulela ukunyamezeka, nezinhlelo zokulungisa imposo, konke lokhu kwenza kube khona izinqumo zokugcina datha. Noma usebenziswa kuzindawo encane zasekhaya noma kuzinhlelo enkulu yezinhlobo, izidiki zaseNAS zihlala yena ubukhulu bezinhlelo zokugcina datha, ukunikeza indlela yokuhlukanisa datha, ukubamba kwindlela yokulondoloza, nokuguqula amaphoyithi.

Izinhawu zokugcinwa kwe-NAS zinikeza amatholakalela amaningi aqondisa ukuthi yinto esenza ngqo ekugcinweni kwamanje. Okokuqala, le zinhawu zinikeza ukubaluleka okukhulu ngokusebenzisa izimfanelo nezilungiselelo ezithunyelwe kusebenzi kuqaphela. Lokhu kubaluleka kuvumela ukunciphisa isikhathi esingasebenzi futhi kuthuthukise ukufinyelelwa kwezethulwini kwebusiness nekudoda endlini. Le zinhawu zinezisombululo eziphumelelayo zokuphatha amandla aphatheke amandla noma kube uyisebenzisa izimo, lokhu kwenza ukuba izindleko zokusebenza ziphansi futhi kunciphe impakho kwi-environment. Ingezo enjengo-RAID ikhipha ukutholakala okuningi, kuvumela ukuthola uhlelo olunye lwamanje lokuqapha okungenayo inxenye yokusebenza noma ukuchanwa kwezethulwini ngokushesha besidingo. Le zinhawu ziyisela kakhulu kuzindlela zokusebenza ngabantu ababili, zihandlela izicelo ezisenokwenzeka ngokushesha ngaphandle kokuthintana nokokhula noma ukuphephile. Zizinemikelo yokulungisa amaphoyinti angenako ukungcola, futhi izibophezo zokulungelela ukungcola kwezinhawu eziningi zivuselela ukungcoliswa komkhumbi. Le zinhawu nazo zinikeza imikelo ephephile yokuphatha intshuku, iyahlisa ubude bokusebenza bakhe futhi ivuselela ukusebenza ngokuphephile xa kusebenzelwa nezinselelo ezinkulu. Ukuthuthukiswa kwezinhawu kwegcina kusona ukuxhumana kunetiyeni kuvumela ukuguqula amafayela ngokushesha futhi kunciphe isikhathi esidingekayo xa sifinyelela kwezethulwini. Ngaphezu kwalokhu, izinhawu zezokugcinwa kwe-NAS zinikeza amagwaro akhulu kanye nezinhlanhla zokuzivuselela, zinikeza ukuthula kwendlela xa kusebenzwa ekugcinweni kwezethulwini. Ukuthuthukiswa kwezinhawu kuvumela abasebenzisi ukuthola uhlelo olunye lwamanje ngokushesha besidingo, futhi livusele ukubaluleka kwezinhlelo. Le zinhawu nazo zinezisombululo zokucache (caching) eziforte zokuthuthukisa izigaba sokufunda nokubhala, okudingekile xa kufinyelelwa amafayela ahluke-hluke.

Ukubuyiselwa kwezimali nezikhali

Izinhawu zokugcinwa kwe-NAS zidizaynwe ngemikhiqizo yokubulisa okungcono okuhlanganisa nazo ukuthola amanye amathikhowodwa wokugcinwa. Kwisigodi somkhiqo wazo kukhona umkhiqo wesilinda esiphumelelayo oqukethwe ngamavibhesheni amathile akunye nezinhlelo zokulungiselela, ezibaluleke kakhulu ukuvikela ubukhona phakathi kwamanqaku amaningi. Lezi zinhawu ziphansi kuzama oluphezulu ukuze zijike ukuthi zibe nemithwalo yokusebenza ngqo, ngezilingo zokuthi izikhathi eziphakeme (MTBF) ziyahluka ngaphezulu kwekhulu elinye le-izikhathi. Ukusebenza kwezinhlelo yekhowudi ethile kunceda ukuhlelela imiphumela futhi kulandele ukungabi namagciwane nemiphumela ye-system. Ngokufanayo, lezi zinhawu zinezinhlelo zokulandelela nokulungisa ubude bendawo ozweni obudingiweyo, engenza kube lula ukusebenza ngaphandle kokusebenza ngokugcwele. Lokhu kucophelela ukuthi izinhawu ze-NAS ziyinto engcono yokukhetha ekugcineni datha kakhulu lapho kudingeka ukutholakala.

Ukusebenza Okuhlelwe Kwesithwebule

Ukubalwa kwezinyezi zokuxeba ne-netyiwekhi ye-NAS zinikeza imiphumela emihle kakhulu kumaqondana okunxianelwe. Lezi zinyezi zinezindlela ezinhle yokugcina izinqubo ezinhle ukuzimeza ukusebenza ngokushesha kwabantu abaningi noma ngokulandelana. I-firmware iyahlukile ukuba yilapho inqubo yokusebenza ebonisa inethiwekhi, okwenza ukuthatha isikhathi esincane futhi kube lula ukuxhumana nokuxaziswa komkhawulo fomu kanye nezinto ezenzekelayo. Kuneqondo lokuhlinzeka ukuthi le ndawo ikhona imiphumela ethile xa kusetshenziselwa ngokuphelele, uyisela amandla abantu abaningi ukufinyelela idatha ngekho ukuthola ukucindezela okuncane. Le zinyezi nazo zinezinhlelo yokuphatha ama-queue owaziwe ukuthi kuzohlukanisa izinkwelo futhi ziphakamise ukusebenza ngendlela elula noma xa kunezinga eliphezulu kwezixhumano zenethiwekhi. Le nhlelo yokudizaynisa ekhona inethiwekhi yenye iziphumo eziphambene nezindaba eziningi kanye nezinto ezingenakho.

Ukujabezela Data Ngokugcwele

Izinhawu zokugcina idatha ye-NAS zifaka phakathi izilaye eziningi zokuphepha idatha ukuthutha isebhithi kanye nokungcoliswa kwemondla egcinwe. Izimathiki zokulungisa iphutha ezahleliyo zisebenza ngokuvamile ukuze balibale kanti kubeke idatha engavunyelwe, nangabe izinhawu zokutholwa futhi zinezindleko ezinikeza amandla okugcina idatha ekufanele ingasebenzi kakhulu. Lezi zinhawu zine-RAID optimization capabilities ezahleliyo ezaqaphela ukuphindaphinda kwe data kanti uphathi kwe data kuzinhawu ezingi. Ukusebenzisa ifirmware elingenhla kanye nezinketho zokubamba ngokwezimali ezikwesicelo zinikeza izindleko ezingenhla zokuphepha idatha engeke ithakazelwe. Iziphumo zokujabulela kanye nezinye izindikimba zivumela abasebenzisi ukuqaphela izinkinga ezingaba yinkimbinkimbi, kuyenza amandla okwenza uhlelo olungile kanti kubeke ukupheli kwe data. Le nto ethulwe ngokuphelele ukuqinisekisa idatha iyakunceda kakhulu abakhethi kanye nabantu abafuna ukuthutha idatha kanti ukuthula.
