LAN thiab SAN sawv ntsug rau Local Area Network thiab Storage Area Network, ntsig txog, thiab ob qho tib si yog thawj qhov chaw cia khoom sib txuas hauv kev siv dav niaj hnub no.
LAN yog ib qho kev sib sau ntawm cov khoos phis tawj thiab cov khoom siv sib txuas uas sib txuas sib txuas lossis wireless txuas rau cov servers nyob hauv thaj chaw sib txawv. SAN hauv ib lub network, ntawm qhov tod tes, muab kev sib txuas ceev ceev thiab yog tsim los rau kev sib txuas lus ntiag tug, tso cai rau kev sib txuas ntawm ntau lub servers nrog ntau yam kev sib koom ua ke.
Yog li ntawd, ob lub ntsiab lus tseem ceeb siv hauv computer network counterpart yog LAN keyboards thiab SAN keyboards. Txawm hais tias LAN keyboards thiab SAN keyboards yog ob qho tib si rau kev sib txuas lus cov ntaub ntawv, lawv muaj qee qhov sib txawv, yog li cia peb saib hauv qab no.
1 Dab tsi yog LAN switching?
LAN switching yog ib txoj kev hloov pob ntawv siv rau kev xa cov pob ntawv ntawm cov khoos phis tawj ntawm LAN hauv ib cheeb tsam hauv cheeb tsam network. Cov txheej txheem no ua lub luag haujlwm tseem ceeb hauv kev tsim network thiab tuaj yeem txhim kho LAN kev ua tau zoo thiab txo cov kev txwv bandwidth. Muaj plaub hom kev hloov LAN:
Multilayer hloov MLS;
Txheej 4 hloov;
Txheej 3 hloov;
Txheej 2 hloov.
Lub LAN hloov ua haujlwm li cas?
Ib qho LAN hloov pauv yog Ethernet hloov uas ua haujlwm raws li IP raws tu qauv thiab muab kev sib txuas yooj yim ntawm cov neeg xa khoom thiab cov neeg txais los ntawm kev sib txuas ntawm cov chaw nres nkoj thiab cov kev sib txuas. Qhov kev npaj no tso cai rau ntau tus neeg siv kawg los sib faib cov peev txheej hauv network. LAN keyboards ua raws li pob ntawv hloov thiab tuaj yeem ua ntau yam ntaub ntawv xa mus ib txhij. Lawv ua qhov no los ntawm kev tshuaj xyuas qhov chaw nyob ntawm txhua cov ntaub ntawv thiab tam sim ntawd coj nws mus rau ib qho chaw nres nkoj tshwj xeeb cuam tshuam nrog cov cuab yeej tau txais.
Lub luag haujlwm tseem ceeb ntawm LAN hloov pauv yog ua kom tiav cov kev xav tau ntawm ib pab pawg neeg siv kom lawv tuaj yeem nkag mus rau cov peev txheej sib koom thiab sib txuas lus seamlessly. Los ntawm kev siv lub peev xwm ntawm LAN keyboards, ib feem loj ntawm cov tsheb khiav hauv lub network tuaj yeem nyob rau hauv cov ntu LAN. Qhov segmentation no ua tau zoo txo qis tag nrho LAN congestion, ua rau smoother cov ntaub ntawv xa mus thiab network ua haujlwm.
2 SAN hloov pauv yog dab tsi?
Storage Area Network SAN switching yog ib txoj hauv kev tshwj xeeb ntawm kev tsim kev sib txuas ntawm cov servers thiab cov chaw khaws cia sib koom ua ke rau tib lub hom phiaj los pab txhawb kev hloov pauv ntawm cov ntaub ntawv ntsig txog kev khaws cia.
Nrog SAN keyboards, nws muaj peev xwm tsim tau loj-loj, siab ceev cia network uas txuas ntau servers thiab nkag mus rau cov ntaub ntawv loj heev, feem ntau ncav cuag petabytes. Hauv lawv txoj haujlwm yooj yim, SAN hloov tau zoo sib koom ua ke ntawm cov neeg siv khoom thiab cov khoom siv khaws cia los ntawm kev tshuaj xyuas cov pob ntawv thiab coj lawv mus rau qhov kawg tau txiav txim siab. Nyob rau tib lub sijhawm, kev hloov pauv hauv cheeb tsam network tau hloov kho kom suav nrog cov yam ntxwv zoo xws li txoj kev rov ua dua, kev kuaj xyuas lub network, thiab tsis siv neeg bandwidth sensing.
Fiber Channel keyboards ua haujlwm li cas?
Fiber Channel hloov yog ib qho tseem ceeb hauv thaj chaw cia khoom network SAN uas pab hloov cov ntaub ntawv zoo ntawm cov servers thiab cov khoom siv cia. Qhov hloov pauv ua haujlwm los ntawm kev tsim kom muaj kev ceev ntiag tug network tsim los rau cov ntaub ntawv khaws cia thiab khaws cia.
Ntawm nws qhov tseem ceeb, Fiber Channel hloov pauv nyob ntawm cov khoom siv tshwj xeeb thiab software los tswj thiab tswj cov ntaub ntawv khiav tsheb. Nws siv Fiber Channel raws tu qauv, kev sib txuas lus muaj zog thiab txhim khu kev qha raws tu qauv tsim rau SAN ib puag ncig. Raws li cov ntaub ntawv raug xa los ntawm tus neeg rau zaub mov mus rau lub cuab yeej cia thiab rov ua dua, nws yog encapsulated hauv Fiber Channel thav ntawv, ua kom cov ntaub ntawv muaj kev ncaj ncees thiab kev sib kis ceev.
SAN hloov ua tus tub ceev xwm tsheb thiab txiav txim siab txoj hauv kev zoo tshaj plaws rau cov ntaub ntawv taug kev los ntawm SAN. Nws tshuaj xyuas qhov chaw nyob thiab qhov chaw nyob hauv Fiber Channel thav ntawv kom muaj txiaj ntsig zoo ntawm cov pob khoom. Qhov kev txawj ntse no txo qis latency thiab congestion, kom ntseeg tau tias cov ntaub ntawv mus txog nws qhov chaw sai thiab ntseeg tau.
Qhov tseem ceeb, Fiber Channel keyboards orchestrate qhov ntws ntawm cov ntaub ntawv hauv SAN, optimizing kev ua tau zoo thiab kev ntseeg siab nyob rau hauv cov ntaub ntawv-intensive ib puag ncig.
3 Lawv txawv li cas?
Sib piv LAN hloov mus rau SAN hloov kuj tuaj yeem xav tias piv rau SAN hloov mus rau lub network hloov, lossis Fiber Channel hloov mus rau Ethernet hloov. Cia peb saib qhov sib txawv tseem ceeb ntawm LAN keyboards thiab SAN keyboards.
Daim ntawv thov sib txawv
LAN keyboards yog Ameslikas tsim rau lub nplhaib token thiab FDDI tes hauj lwm thiab tom qab ntawd tau hloov los ntawm Ethernet. LAN keyboards ua lub luag haujlwm tseem ceeb hauv kev txhim kho tag nrho cov kev ua tau zoo ntawm LANs thiab daws cov teeb meem bandwidth uas twb muaj lawm. LANs tuaj yeem txuas nrog ntau yam khoom siv xws li cov ntaub ntawv servers, cov tshuab luam ntawv, cov chaw khaws cia, desktops, thiab lwm yam, thiab LAN keyboards tuaj yeem tswj xyuas cov tsheb khiav ntawm cov ntsiab lus sib txawv no.
Thiab SAN hloov yog tsim los rau cov kev sib txuas ua haujlwm siab kom ntseeg tau tias tsis tshua muaj latency thiab tsis hloov cov ntaub ntawv. Nws tau ua tib zoo tsim los tswj cov kev lag luam hnyav hnyav, tshwj xeeb tshaj yog nyob rau hauv kev ua haujlwm siab Fiber Channel tes hauj lwm. Txawm hais tias Ethernet lossis Fiber Channel, qhov chaw cia khoom network hloov pauv tau mob siab rau thiab ua kom zoo los tswj cov tsheb thauj mus los.
Kev ua tau zoo sib txawv
Feem ntau, LAN keyboards siv tooj liab thiab fiber ntau cuam tshuam thiab ua haujlwm ntawm IP-based Ethernet tes hauj lwm. Txheej 2 LAN switching muaj cov txiaj ntsig ntawm kev hloov cov ntaub ntawv ceev thiab tsawg latency.
Nws ua tau zoo hauv cov yam ntxwv xws li VoIP, QoS thiab tshaj tawm bandwidth. Txheej 3 LAN keyboards muaj cov yam ntxwv zoo ib yam li routers. Raws li rau Txheej Txheej 4 LAN Hloov, nws yog ib qho kev tshaj tawm ntawm Txheej Txheej 3 LAN Hloov uas muaj cov ntawv thov ntxiv xws li Telnet thiab FTP. Tsis tas li ntawd, LAN Switch txhawb cov txheej txheem suav nrog tab sis tsis txwv rau SNMP, DHCP, Apple Talk, TCP /IP, thiab IPX.Tag nrho hauv tag nrho, LAN Hloov yog tus nqi-zoo, yooj yim-rau-xa tawm kev sib tham daws teeb meem uas zoo tagnrho rau kev lag luam thiab kev xav tau kev sib txuas siab.
SAN keyboards tsim nyob rau hauv lub hauv paus ntawm iSCSI cia tes hauj lwm, incorporating Fiber Channel thiab iSCSI technologies. Qhov tseem ceeb tshaj plaws yog tias SAN keyboards muaj peev xwm khaws cia zoo tshaj LAN keyboards. Fiber Channel keyboards kuj tuaj yeem yog Ethernet keyboards.
Qhov zoo tshaj plaws, Ethernet-based SAN hloov yuav mob siab rau kev tswj xyuas cov tsheb khiav hauv IP chaw cia khoom network, yog li ua kom ntseeg tau tias kev ua tau zoo. Tsis tas li ntawd, los ntawm kev sib txuas ntawm SAN keyboards, qhov dav SAN network tuaj yeem tsim los txuas ntau lub servers thiab chaw nres nkoj.
4 Kuv yuav xaiv txoj cai hloov li cas?
Thaum xav txog LAN vs. SAN, kev xaiv ntawm LAN hloov lossis SAN hloov ua qhov tseem ceeb. Yog tias koj cov kev xav tau suav nrog cov txheej txheem sib qhia cov ntaub ntawv xws li IPX lossis AppleTalk, tom qab ntawd tus IP-based LAN hloov yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv cia. Hloov pauv, yog tias koj xav tau qhov hloov pauv los txhawb Fiber Channel-raws li kev cia khoom, kev hloov pauv hauv cheeb tsam network tau pom zoo.
LAN keyboards pab txhawb kev sib txuas lus hauv LAN los ntawm kev sib txuas cov khoom siv hauv tib lub network.
Fiber Channel keyboards, ntawm qhov tod tes, feem ntau yog siv los txuas cov cuab yeej cia rau cov servers kom muaj txiaj ntsig zoo thiab khaws cov ntaub ntawv. Cov keyboards no sib txawv ntawm tus nqi, kev ua kom muaj peev xwm, topology, kev ruaj ntseg, thiab muaj peev xwm cia. Qhov kev xaiv ntawm lawv nyob ntawm qhov kev siv tshwj xeeb.
LAN keyboards yog pheej yig thiab yooj yim rau configure, thaum SAN keyboards kuj kim thiab yuav tsum tau complex configurations.
Hauv luv luv, LAN keyboards thiab SAN keyboards yog ntau hom kev sib txuas hauv network, txhua tus ua lub luag haujlwm tshwj xeeb hauv lub network.
