Inkcazo yeNgcaciso yeMicandelo yeNgcaciso kunye noNxibelelwano oluCwangcisiweyo
Inethiwekhi yokugcina indawo (ii-SANs) kunye nokugcinwa kwenethiwekhi eqhotyoshelweyo (NAS) zombini zibonelela ngesisombululo sokugcina inethiwekhi. I-NAS iyisisitoreji esisodwa sokugcina esisebenza kwiifayile zeedatha, ngelixa i-SAN yinkonzo yendawo yezixhobo ezininzi.
Ukwahlukana phakathi kwe-NAS ne-SAN kunokubonwa xa kuqhathaniswa nokukhangela kwabo kunye nendlela abadibene ngayo kwinkqubo, kwakunye nendlela ezinye iifowunxibelelwano nazo. Nangona kunjalo, amanye amaxesha ngamanye amaxesha asetyenziswa kunye kunye nokwenza into eyaziwayo njenge-SAN ehlangeneyo.
SAN vs. NAS Technology
Iyunithi ye-NAS iquka idivaysi yehadiweyo edibeneyo edibanisa kwinethiwekhi yendawo , ngokuqhelekileyo ngokusebenzisa uxhumano lwe- Ethernet . Le seva ye-NAS iqinisekisa abaxhasi kwaye ilawula imisebenzi yefayili ngendlela efana neyofana neenkonzo zedifayile zendabuko, kwiiprotokholi ezinxibelelweyo ezisemgangathweni.
Ukunciphisa iindleko ezenzeka kwiinkonzo zefayile zendabuko, izixhobo ze-NAS ziqhutywa ngokubanzi kwinkqubo yokusebenza efakwe kwi-hardware elula kunye nokungabikho kwimizila efana ne- monitor okanye ikhibhodi kwaye kunoko kulawulwa ngeso sixhobo sesiphequluli.
I-SAN isebenzisa ngokubanzi ukudibanisa kweFiber Channel kwaye idibanisa iisethi zokugcina izixhobo ezikwazi ukwabelana ngolwazi omnye nomnye.
I-NAS ebalulekileyo kunye ne-SAN Benefits
Umlawuli wekhaya okanye umnxibelelwano omncinci wezoshishino unokuxhuma enye ifowuni ye-NAS kwinethiwekhi yendawo. Isixhobo ngokwawo siyinethiwekhi yomnatha , kufana neekhomputer kunye nezinye iifayile ze-TCP / IP , zonke zazo zigcina idilesi ye-IP yazo kwaye ziyakwazi ukunxibelelana ngokufanelekileyo kunye nezinye izixhobo ezinxibelelwano.
Ngenxa yokuba umnxibelelwano oqhotyoshelweyo oqhotyoshelweyo uqhotyoshelwe kwinethiwekhi , zonke iifowuni kweso sixhobo zinokufikelela okulula (kunikezelwe ukuba iimvume ezifanelekileyo zimiselwe). Ngenxa yobume babo bobukhulu, amadivayisi e-NAS anika indlela elula yokuba abasebenzisi abaninzi bakwazi ukufikelela kwedatha efanayo, ebalulekileyo kwiimeko apho abasebenzisi babambisana khona kwiiprojekthi okanye basebenzisa imigangatho efanayo yenkampani.
Ukusebenzisa inkqubo yesofthiwe enikwe i-NAS yezinto, umlawuli wenethwekhi unokusekela izixhobo ezizenzekelayo okanye zezikhokelo kunye neefayile zeefayile phakathi kwe-NAS kunye nazo zonke izixhobo ezixhunyiwe. Ngoko ke, isistim se-NAS sinokusetyenziswa kwesizathu esichaphazelekayo: ukukhupha idatha yendawo kwindawo yesitoreji yokugcina inethiwekhi isitsha esikhulu sokugcina.
Oku kuncedo nje kuphela ukuqinisekisa ukuba abasebenzisi abalahlekelwa yidatha, ekubeni i-NAS ingaxhaswa kwishedyuli eqhelekileyo kungakhathaliseki ukuba ngumsebenzisi wokugqibela ukukhupha, kodwa kwakhona ukunika ezinye iifowuni zendawo indawo yokugcina iifayile ezinkulu, iifayile ezinkulu eziqhelekileyo zabelana nabanye abasebenzisi benethiwekhi.
Ngaphandle kwe-NAS, abasebenzisi kufuneka bafumane enye (rhoqo ngokukhawuleza) kuthetha ukuthumela idatha kwezinye iifowuni kwinethiwekhi, njengokuba i-imeyile okanye ngokomzimba nge- flash drives . I-NAS inamagigabytes amaninzi okanye i- terabytes yedatha, kwaye abalawuli banokufaka amandla okugcina okongeziweyo kumnatha wabo ngokufaka iiNAS ezongezelelweyo, nangona i-NAS nganye isebenza ngokuzimela.
Abalawuli bezonxibelelwano ezinkulu zorhwebo banokufuna i-terabytes ezininzi zendawo yokugcinwa kwefayili okanye imisebenzi yokudlulisa ifayile ephezulu. Ngoxa ukufaka umkhosi weeNAS ezininzi izixhobo azikho ukhetho olufanelekileyo, abalawuli banokuthi bafake i-SAN eneenkcukacha eziphezulu zokusebenza kwidiskthi ukwenzela ukubonelela ngokufanelekileyo kunye nokusebenza.
Nangona kunjalo, i-SAN ayisoloko isemzimbeni. Unokudala ii-SANs ezintle (ii-VSAN) ezichazwe yiprosoft software. I-SAN ezintle zilula ukulawula kwaye zinikezela ngokungahambi kakuhle kwazo kuba zixhobo ezizimeleyo kwaye zilawulwa ngokupheleleyo kwi-software elula ukuyitshintsha.
I-SAN / NAS Convergence
Njengoko ubuchwephesha be-intanethi njengeTCP / IP kunye ne-Ethernet banda emhlabeni jikelele, ezinye iimveliso ze-SAN zenza utshintsho kwiFiber Channel ukuya kwindlela efanayo ye-IP esebenzisa i-NAS. Kwakhona, ngokuphucula ngokukhawuleza kwisekhnoloji yokugcinwa kwe diski, amadivayisi e-NAS anamhlanje anikezela amandla kunye nokusebenza okokuba kwakunokwenzeka kuphela nge-SAN.
Ezi zimbini zoshishino zikhokelela ekuhambeni kwe-NAS kunye ne-SAN ukufikelela kwisitoreji sokunxibelelwano, ngokudala ngokukhawuleza ukudala i-speed-speed, amandla aphakamileyo, iisetyenzisi zenethiwekhi.
Xa i-SAN kunye ne-NAS zihlanganiswa kwidivaysi enye ngale ndlela, ngamanye amaxesha kuthiwa "i-SAN edibeneyo," kwaye ngokuqhelekileyo imeko ifowuni iyisisetshenziswa se-NAS esisebenzisa kuphela iteknoloji ye-SAN.
