Esikhathini sedijithali, ukugcinwa kwedatha nokufinyeleleka sekuyinto ehamba phambili kukho kokubili ukusetshenziswa komuntu siqu nokochwepheshe. I-Network Attached Storage (NAS) inikezela ngesixazululo esisebenza ngezindlela eziningi, esisebenza njengehabhu elimaphakathi ledatha yakho. Lo mhlahlandlela ophelele uhlola ubunkimbinkimbi be-NAS, ukusebenza kwayo, izinzuzo, izithiyo, kanye nendlela yokwenza ukuthi ikusebenzele.

Yini I-Network Attached Storage?
I-Network Attached Storage (NAS) iyithuluzi elizinikele lokugcina ifayela elivumela abasebenzisi abaningi kanye namadivayisi amaklayenti ahlukahlukene ukuthi athole idatha kumthamo wediski ophakathi nendawo. Abasebenzisi bangafinyelela lesi sitoreji esabiwe ngenethiwekhi, okwenza i-NAS ibe ithuluzi elibalulekile lokwabelana ngedatha nokusebenzisana ezisekelweni ezahlukene. Ngokungafani nesitoreji esinamathiselwe ngokuqondile esingokwesiko (i-DAS) esixhunywe kukhompuyutha eyodwa, i-NAS isebenzela amaklayenti amaningi ngenethiwekhi, enikeza ukuguquguquka okukhulu nokuqina.
Izinhlelo ze-NAS zenzelwe ukuthi zibe lula ukuzilungiselela nokuphatha, okuzenza zifinyeleleke kubo bobabili abasebenzisi basekhaya namabhizinisi. Ziza ngosayizi namakhono ahlukahlukene, kusukela kumayunithi angangena ehhovisi lasekhaya kuye ezixazululweni ezinkulu zezindawo zamabhizinisi. Umnyombo wokusebenza kwe-NAS ulele ekhonweni layo lokunikeza ukufinyelela ngesikhathi esisodwa kumafayela, okuwenza abe yisixazululo esikahle sezindawo zokusebenza ngokubambisana, ukusakazwa kwe-multimedia, nezisombululo eziyisipele.
Ubuchwepheshe obulandela i-NAS bakhelwe phezu kwezinqubo ezisekelwe kufayela ezifana ne-NFS (evamile ezinhlelweni ze-UNIX), i-SMB/CIFS (Isivimbeli Somlayezo Weseva/Isistimu Yefayela Ye-inthanethi Evamile, esetshenziswa ne-Microsoft Windows), kanye ne-AFP (esetshenziswa namadivayisi we-Apple). Lezi zivumelwano zivumela i-NAS ukuthi ibonakale kumadivayisi eklayenti njengokungathi isitoreji esinamathiselwe ngokuqondile, nakuba ingase ibekwe endaweni ehlukile yendawo.
Sisebenza kanjani i-Network Attached Storage?
Emgogodleni wayo, i-NAS isebenza ngokuxhuma kunethiwekhi yendawo (LAN) ngoxhumano olujwayelekile lwe-Ethernet. Lokhu kuxhumana kuvumela amadivayisi e-NAS ukuthi axhumane namadivayisi amaningi kunethiwekhi, anikeze amafayela futhi anike amandla ukufinyelela nokwabelana kwedatha. Isistimu yokusebenza yedivayisi ye-NAS, ngokuvamile inguqulo ehlelekile ye-Linux noma enye i-OS esebenza kahle kunethiwekhi, yakhelwe ngokuqondile ukugcinwa kwefayela nokwabelana.
Izinhlelo ze-NAS ziyahlukahluka ngobunkimbinkimbi, kusukela ekusetheni ikhaya okuyisisekelo nge-hard drive eyodwa kuya kuzixazululo zebhizinisi eziyinkimbinkimbi ezinamamojula amaningi okugcina nezici ezithuthukisiwe zokuvikela idatha njenge-RAID (I-Redundant Array of Independent Disks), izifinyezo, kanye nokubethela kwesikhathi sangempela. Ukufakwa kokucushwa kwe-RAID kumadivayisi e-NAS kuqinisekisa ukuphindaphinda kwedatha, kuvikela ekulahlekeni kwedatha uma kwenzeka ukwehluleka kwe-hard drive.
Esinye sezici ezibalulekile ze-NAS wukuba lula kwayo ukuphatha idatha. Ngesixhumi esibonakalayo esisekelwe kuwebhu, abasebenzisi bangamisa kalula futhi baphathe ukugcinwa kwedatha yabo, bamise izimvume zabasebenzisi, futhi benze izipele. Lokhu kuphatha okusebenziseka kalula kuyinzuzo enkulu, enciphisa isidingo samakhono akhethekile we-IT ukuze kugcinwe futhi kuvikeleke uhlelo lokugcina.
Izinzuzo kanye nezithiyo ze-Network Attached Storage
Izinzuzo ze-NAS ziningi, zinikeza ukufinyeleleka kwedatha okuthuthukisiwe, amandla okwabelana, nokuphathwa kwedatha okumaphakathi. Emabhizinisini, i-NAS yenza ukubambisana kube lula ngokuvumela abasebenzi ukuthi bafinyelele amafayela abelwe ngaphandle komthungo, kungakhathaliseki ukuthi iyiphi isistimu yokusebenza noma indawo. Iphinde inikeze ukukala, okwenza amabhizinisi akwazi ukwengeza umthamo wesitoreji ngaphandle kokuphazamisa ukusebenza okukhona.
Kodwa-ke, i-NAS ayinazo izithiyo zayo. Ukuncika kwenethiwekhi kusho ukuthi ukusebenza nokufinyeleleka kwe-NAS kungaphansi kwezimo zenethiwekhi kanye nomkhawulokudonsa. Izindawo ezinethrafikhi ephezulu zingase zibe nezikhathi zokufinyelela kancane kwedatha phakathi nezikhathi eziphakeme kakhulu. Ukwengeza, ngenkathi izinhlelo ze-NAS ngokuvamile zivikelekile, zisesengozini yokuhlaselwa okusekelwe kunethiwekhi, okwenza imikhuba yokuphepha yenethiwekhi ibaluleke kakhulu.
Okunye okucatshangelwayo yizindleko zokuqala kanye nokugcinwa okuqhubekayo. Nakuba i-NAS ingakwazi ukonga imali ngokuhamba kwesikhathi, ikakhulukazi kumabhizinisi adinga inani elikhulu lesitoreji esabiwe, ukutshalwa kwezimali kwangaphambili kungaba okubalulekile. Ukunakekelwa okuvamile kanye nokuthuthukiswa okungenzeka nakho kunomthelela ezindlekweni eziphelele zobunikazi.
Ungasikhetha kanjani Isitoreji Esinamathiselwe Inethiwekhi
Ukukhetha i-NAS efanele kuncike ezintweni ezimbalwa, okuhlanganisa izidingo zesitoreji, isabelomali, nokusetshenziswa okuhlosiwe. Ukuze usebenzise ihhovisi lomuntu siqu noma elincane, i-NAS elula, enedrayivu eyodwa ingase yanele. Kodwa-ke, amabhizinisi noma abasebenzisi abanemitapo yolwazi yemidiya ebanzi bangase badinge i-NAS ye-multi-bay enokusekelwa kwe-RAID ukuze kuvikelwe idatha eyengeziwe namandla.
Lapho ukhetha i-NAS, cabangela ukusebenzisana kwedivayisi nenethiwekhi yakho ekhona kanye namadivayisi. Bheka izinhlelo ze-NAS ezisekela imigomo yakho edingekayo futhi zinikeze ukusebenza okudingekayo kwezinhlelo zakho zokusebenza ezithile. Ukwengeza, hlola izinketho zokukala ze-NAS, uqiniseke ukuthi ingakhula nezidingo zakho zesitoreji.
Izici zokuphepha nazo zibalulekile. Khetha amadivayisi e-NAS anikeza ukubethela, izilawuli zokufinyelela ezivikelekile, nezibuyekezo zesofthiwe ezivamile ukuze uvikele idatha yakho. Okokugcina, cabangela ukusebenziseka kalula nezici zokuphatha, njengoba isixhumi esibonakalayo esisebenziseka kalula singanciphisa kakhulu isikhathi nomzamo odingekayo ukuze ulawule isitoreji sakho sedatha.
Indlela yokusebenzisa Isitoreji Esinamathiselwe Senethiwekhi
Ukusetha nokusebenzisa i-NAS kuhilela izinyathelo ezimbalwa ezibalulekile. Ekuqaleni, uzodinga ukuxhuma idivayisi ye-NAS kunethiwekhi yakho, ngokuvamile ngentambo ye-Ethernet. Uma isixhunyiwe, i-NAS izolungiswa ngokusebenzisa isixhumi esibonakalayo esisekelwe kuwebhu. Le nqubo yokusetha ihlanganisa ukuqalisa amadrayivu, ukudala amavolumu esitoreji, nokumisa izilungiselelo zenethiwekhi.
Ukuze uyisebenzise ngempumelelo, hlela idatha yakho ibe amafolda abelwe futhi usethe ama-akhawunti abasebenzisi nezimvume zokulawula ukufinyelela. Njalo yenza ikhophi yasenqolobaneni yedatha ebalulekile kokubili ngaphakathi nangaphandle kwesayithi ukuze uqinisekise ukunganaki kwedatha nokuphepha. Ukwengeza, sebenzisa izici ezinikezwa yi-NAS yakho, njengokusakaza bukhoma kwemidiya, ukufinyelela ukude, nezinhlelo zokusebenza zezinkampani zangaphandle, ukuze uthuthukise ukuphathwa kwedatha yakho nokufinyeleleka.
Gcina i-NAS yakho ngokugcina i-firmware yayo isesikhathini futhi ugade impilo yayo ngokusebenzisa isixhumi esibonakalayo sokuphatha. Izibuyekezo ezivamile azithuthukisi kuphela ukusebenza nokuphepha kodwa futhi ziqinisekisa ukuthi i-NAS yakho isebenza kahle.
Isiphetho
I-Network Attached Storage inikeza isixazululo esivumelana nezimo nesisebenzayo sokuphatha nokufinyelela idatha kuwo wonke amadivayisi amaningi. Ngokuqonda ukuthi i-NAS isebenza kanjani, izinzuzo zayo kanye nezithiyo, nokuthi ungayikhetha kanjani futhi uyisebenzise ngempumelelo, abasebenzisi bangathuthukisa amasu abo okugcina idatha. Kungakhathaliseki ukuthi okokusebenzisela umuntu siqu, amabhizinisi amancane, noma amabhizinisi amakhulu, i-NAS ihlinzeka ngendlela enwebekayo, evikelekile, nefinyelelekayo yokugcina nokwabelana ngokuqukethwe kwedijithali.
