Incazelo Yezintandokazi Zokugcinwa Kwamasitoreji Nesitoreji Esixhunywe Ngenethiwekhi
Indawo yokugcina indawo (SANs) kanye nesitoreji esithintekayo senethiwekhi (NAS) zombili zihlinzeka ngezixazululo zokugcina izinethiwekhi. I-NAS iyisidingo esisodwa sokugcina esisebenza kumafayela wedatha, kuyilapho iSAN inethiwekhi yendawo yamadivayisi amaningi.
Ukungafani phakathi kwe-NAS ne-SAN kungabonakala uma kuqhathaniswa neklabhuthi yabo nokuthi baxhumeke kanjani ohlelweni, nokuthi amanye amadivaysi axhumana kanjani nabo. Kodwa-ke, lezi zikhathi ezithile zisetshenziselwa ndawonye ukudala lokho okuyaziwa njenge-SAN ehlanganisiwe.
I-SAN vs. NAS Technology
Iyunithi ye-NAS ihlanganisa idivaysi yehadiwe elalinikezele elixhuma kwinethiwekhi yendawo , ngokuvamile ngokusebenzisa uxhumano lwe- Ethernet . Le seva ye-NAS iqinisekisa amaklayenti futhi ilawula imisebenzi yefayili ngendlela efanayo namaseva wesifayela wefayili, ngokusebenzisa izivumelwano zenethiwekhi ezisungulwe kahle.
Ukunciphisa izindleko ezenzeka ngamaseva wezintambo zendabuko, amadivayisi we-NAS ngokuvamile agijima uhlelo lokufaka oluhlanganisiwe kwi-hardware elula futhi engenakho amakhemikhali afana nokuqapha noma ikhibhodi futhi esikhundleni salokho ephethwe ngokusebenzisa ithuluzi lesiphequluli.
I-SAN isebenzisa izixhumanisi ze- Fiber Channel futhi ixhuma isethi yamadivayisi wokugcina ekwazi ukwabelana ngemininingwane komunye nomunye.
I-NAS ebalulekile ne-SAN Izinzuzo
Umlawuli wekhaya noma inethiwekhi yebhizinisi elincane angakwazi ukuxhuma idivayisi eyodwa ye-NAS kwinethiwekhi yendawo. Idivayisi ngokwayo iyi- node yenethiwekhi , kufana namakhompyutha namanye amadivayisi we- TCP / IP , konke okugcina ikheli le-IP lakho futhi lingakwazi ukuxhumana ngokuphumelelayo namanye amadivaysi anethiwekhi.
Njengoba kunikezwe ukuthi inethiwekhi yesitoreji enamathiselwe inethiwekhi ifakwe kwinethiwekhi , wonke amanye amadivayisi kuleyo nethiwekhi ayifinyelela kalula (enikeziwe ukuthi izimvume ezifanele zisethiwe). Ngenxa yemvelo yabo, amadivayisi we-NAS anikeza indlela elula yabasebenzisi abaningi ukufinyelela idatha efanayo, ebalulekile ezimweni lapho abasebenzisi bahlanganyela khona kumaphrojekthi noma basebenzisa izindinganiso ezifanayo zenkampani.
Ukusebenzisa uhlelo lwesofthiwe olunikezwa i-NAS hardware, umlawuli wenethiwekhi angasetha ama-backups okuzenzakalelayo noma amakhophi namakhophi wefayela phakathi kwe-NAS nawo wonke amanye amadivayisi axhunyiwe. Ngakho-ke, idivayisi ye-NAS ibuye isebenze ngesizathu esihlukile: ukukhipha idatha yendawo kudivayisi yesitoreji senethiwekhi isitsha esikhulu sokugcina isitoreji.
Lokhu kuyasiza hhayi kuphela ukuqinisekisa ukuthi abasebenzisi abalahlekelwa yidatha, ngoba i-NAS ingaxhaswa esimisweni esivamile kungakhathaliseki ikhono lomsebenzisi wokugcina, kepha futhi ukunikeza amanye amadivaysi enethiwekhi indawo yokugcina amafayela amakhulu, ikakhulukazi amafayela amakhulu avame ukuhlanganyela phakathi kwabanye abasebenzisi benethiwekhi.
Ngaphandle kwe-NAS, abasebenzisi kufanele bathole enye (ngokuvamile ehamba kancane) kusho ukuthumela idatha kwamanye amadivaysi kunethiwekhi, njengama-imeyili noma ngokomzimba ngokushayela . I-NAS iphethe ama-gigabytes amaningi noma i- terabytes yedatha, futhi abaphathi banganezela amandla okugcina okungeziwe kwinethiwekhi yabo ngokufaka amadivayisi we-NAS engeziwe, nakuba i-NAS ngayinye isebenza ngokuzimela.
Abaphathi bamanethiwekhi amakhulu webhizinisi bangadinga ama-terabytes amaningi wesitoreji sefayela eliphakathi noma imisebenzi yokudlulisa ifayela eliphezulu kakhulu. Ngenkathi ukufaka ibutho lamadivayisi amaningi we-NAS akuyona into ewusizo, abaphathi bangakwazi ukufaka i-SAN equkethe i-disk ephezulu yokusebenza ukuze banikeze ukusabalalisa okudingekayo nokusebenza.
Kodwa-ke, ama-SAN ahlale engokomzimba njalo. Ungakwazi futhi ukudala i-SANs ebonakalayo (i-VSAN) echazwe uhlelo lwesofthiwe. I-Sans Virtual kulula ukuphatha futhi inikeze ukuhleleka okungcono ngoba i-hardware emele futhi ilawulwa ngokuphelele nge-software elula ukushintsha.
I-SAN / NAS Convergence
Njengoba ubuchwepheshe be-intanethi njengoTCP / IP ne-Ethernet banda emhlabeni kabanzi, ezinye imikhiqizo ye-SAN yenza ushintsho kusuka ku-Fiber Channel kuya ku-IP esebenzisa indlela esebenzisa i-NAS. Futhi, ngokuthuthukiswa okusheshayo ku-disk ubuchwepheshe bokugcina, amadivayisi we-NAS yanamuhla manje anikeza amandla nokusebenza okwakungenzeka kuphela nge-SAN.
Lezi zimboni ezimboni ziye zaholela ekuguqulweni okuyingxenye ye-NAS ne-SAN esondela kwisitoreji senethiwekhi, ngokudala ukudala ama-network esheshayo, amandla aphezulu, ama-network atholakalayo.
Uma i-SAN ne-NAS behlangene ndawonye kudivayisi eyodwa ngale ndlela, ngezinye izikhathi kuthiwa "yi-SAN ehlanganisiwe," futhi ngokuvamile kuvame ukuthi idivayisi iyisetshenziswa se-NAS esisebenzisa nje ubuchwepheshe obufanayo ngemuva kwe-SAN.
