I-NAS, i-SAN, nezinye izinhlobo zeSitoreji Senethiwekhi
Isitoreji senethiwekhi yigama elisetshenziselwa ukuchaza idivayisi yokugcina (ngokuvamile amadivaysi amaningi ahlanganiswe ndawonye) atholakala kwinethiwekhi.
Lolu hlobo lwesitoreji lugcina amakhophi wedatha kuwo wonke uxhumano lwenethiwekhi yendawo ye -speed speed (LAN) futhi lenzelwe ukubuyisa amafayela, yolwazi, nolunye ulwazi endaweni ephakathi okungafinyeleleka kalula ngezinhlelo ezijwayelekile zenethiwekhi namathuluzi.
Okwenza isitoreji senethiwekhi kubalulekile
Isitoreji yisici esibalulekile kunoma iyiphi ikhompyutha. Izinkinobho ezinzima kanye nezikhiye ze- USB , isibonelo, zenzelwe ukubamba idatha yomuntu siqu eduze nendawo lapho kudingeke khona ukufinyelela ulwazi, njengokungaphakathi ngaphakathi noma eceleni kwekhompyutha yabo.
Noma kunjalo, uma lezi zinhlobo zesitoreji sendawo zihluleka, futhi ikakhulukazi uma zingagcinwa ku-intanethi , idatha ilahlekile. Ukwengeza, inqubo yokwabelana kwedatha yendawo namanye amakhompiyutha ingadla isikhathi, futhi ngezinye izikhathi inani lokugcina lendawo elitholakalayo alitholakali ukugcina konke okufunayo.
Isitoreji senethiwekhi sibhekana nalezi zinkinga ngokuhlinzeka ngemfihlo yedatha yangaphandle yedatha kuwo wonke amakhompyutha e-LAN ukwabelana ngokuphumelelayo. Ukukhulula isikhala sesitoreji sendawo, amasistimu okugcina inethiwekhi nawo ngokuvamile asekela izinhlelo zokulondoloza ezizenzakalelayo ukuvimbela ukulahlekelwa kwedatha okubalulekile.
Isibonelo, inethiwekhi enekhompyutha engama-250 ehlanganisa isakhiwo esikhulu esinamapulangwe amaningi, ingazuza kusuka kwisitoreji senethiwekhi. Ngokufinyelela kwenethiwekhi kanye nezimvume ezifanele, abasebenzisi bangakwazi ukufinyelela amafolda kudivayisi yesitoreji senethiwekhi ngaphandle kokukhathazeka ukuthi lawo mafayela ashintshe ikhono lokugcina lendawo.
Ngaphandle kwesisombululo sesitoreji senethiwekhi, ifayela elidinga ukufinyelelwa ngabasebenzisi abaningi abangasondelene ngokomzimba kufanele lithumele nge-imeyli, lihanjiswe ngesandla ngento efana ne- flash drive , noma ilayishwe ku-intanethi ukuze ilayishwe futhi ngakwesokunxele. Zonke lezi zixazululo ezihlukile zenza isikhathi sokugcina, isitoreji, kanye nokukhathazeka kwangasese okunciphisa ukugcina okuphakathi.
Isitoreji Senethiwekhi ye-SAN ne-NAS
Izinhlobo ezimbili ezijwayelekile zesitoreji senethiwekhi zibizwa ngokuthi i- Storage Area Network (SAN) ne- Network Attached Storage (NAS) .
I-SAN ngokuvamile isetshenziselwa amanethiwekhi wezamabhizinisi futhi isebenzisa amaseva aphezulu, ama-disk high disk arrays, nobuchwepheshe bokuxhumana be- Fiber Channel . Amanethiwekhi asekhaya asebenzisa i-NAS, efaka ukufaka i- hardware ebizwa ngamadivayisi we-NAS ku-LAN nge- TCP / IP .
Bheka Ukuhlukana Phakathi kwe-SAN ne-NAS ukuthola olunye ulwazi.
Izinsiza Zokugcina Inethiwekhi Ne-Cons
Nasi isifinyezo sezinye zezinzuzo nezinsalela zesitoreji sefayela kunethiwekhi:
Izinzuzo:
- Inikeza indlela elula yamadivaysi enethiwekhi ukufinyelela kumafayela afanayo
- Kulula ukusekela idatha yabasebenzisi abaningi lapho begcina amafayela abo endaweni efanayo
- Isitoreji senethiwekhi sisindisa amadivayisi wesitoreji esendaweni ekufinyeleleni amandla
- Isitoreji sendawo esincane sidinga ukuthengwa kubasebenzisi uma sigcina iningi layo kunethiwekhi
Umthengi:
- Amadivaysi axhunyiwe kwinethiwekhi akakwazi ukufinyelela idatha (isb. Inethiwekhi encane ivimbela abasebenzisi ukuthi bangafinyeleli amafayela abo)
- Ukukhonza amafayela abiwe kubasebenzisi kudinga izimvume ezifanele ukusethwa, okungadla isikhathi lapho abasebenzisi abaningi abasha behlelwe ngesikhathi esisodwa
- Isitoreji esiningi senethiwekhi sidinga isikhala esiphezulu sokugcina isikhala
