LAN neSAN inomiririra Local Area Network uye Storage Area Network, zvichiteerana, uye ese ari maviri ekutanga ekuchengetedza network masisitimu mukushandiswa kwakapararira nhasi.
A LAN muunganidzwa wemakomputa uye maperipheral anogovera waya kana isina waya yekutaurirana link kumaseva ari munzvimbo dzakasiyana siyana. A SAN mune network, kune rumwe rutivi, inopa yakakwirira-kumhanya yekubatanidza uye yakagadzirirwa kune yakavanzika network, ichibvumira isina musono kubatana kweakawanda maseva ane akasiyana-siyana ekuchengetera zvishandiso.
Saka nekudaro, izvo zviviri zvakakosha zvinoshandiswa mukombuta network inofananidzira maLAN switch uye SAN switch. Kunyangwe LAN switch uye SAN switches ese ari maviri chiteshi chekutaurirana data, ane mimwe misiyano, saka ngatitarisei pazasi.
1 Chii chinonzi LAN switching?
LAN switching inzira yekuchinjisa pakiti inoshandiswa kufambisa mapaketi pakati pemakomputa paLAN mukati menzvimbo yenzvimbo network. Iyi tekinoroji inoita basa rakakosha mukugadzira netiweki uye inogona kuvandudza zvakanyanya kushanda kweLAN uye kudzikamisa bandwidth. Kune marudzi mana eLAN switching:
Multilayer switching MLS;
Layer 4 kuchinja;
Layer 3 kuchinja;
Layer 2 switching.
Iyo LAN switch inoshanda sei?
A LAN switch is Ethernet switch inoshanda yakavakirwa paIP protocol uye inopa inochinjika yekubatanidza pakati pevanotumira nevanogamuchira kuburikidza neakabatana network yezviteshi uye zvinongedzo. Iyi gadziriro inobvumira nhamba huru yevashandisi vekupedzisira kugovera zviwanikwa zvetiweki. LAN switches inoshanda semapaketi ekuchinja uye inogona kubata akawanda data transmissions panguva imwe chete. Ivo vanoita izvi nekuongorora kero yekuenda kwega yega data furemu uye nekukasira kuitungamira kune chaiyo chiteshi chine chekuita neyakagadzirirwa kugashira mudziyo.
Basa rekutanga reLAN switch ndeyekuzadzisa zvinodiwa neboka revashandisi kuitira kuti vagone kuwana zvakagovaniswa zviwanikwa uye kutaurirana zvisina musono. Nekushandisa kugona kweLAN switch, chikamu chikuru chetiweki traffic chinogona kuwanikwa mune dzakati compact LAN zvikamu. Iyi segmentation inonyatso kuderedza kuzara kweLAN, zvichikonzera kufambiswa kwedata kwakapfava uye kushanda kwetiweki.
2 Chii chinonzi SAN switching?
Storage Area Network SAN switching inzira yakasarudzika yekugadzira hukama pakati pemaseva nemadziva ekuchengetera akagovaniswa nechinangwa chega chekufambisa kufambiswa kwedata rine chekuita nekuchengetedza.
Nekuchinjisa kweSAN, zvinokwanisika kugadzira hukuru-hukuru, hukuru hwekuchengetera network hunobatanidza maseva mazhinji uye kuwana huwandu hukuru hwe data, kazhinji inosvika petabytes. Mukushanda kwavo kwekutanga, SAN inochinja inonyatso kurongedza traffic pakati pemaseva nemidziyo yekuchengetera nekuongorora mapaketi uye nekuatungamira kune akafanotemerwa magumo. Nekufamba kwenguva, network nharaunda yekuchengetera switch yakashanduka kuti ibatanidze maficha epamberi senge nzira redundancy, network diagnostics, uye otomatiki bandwidth kunzwa.
Fiber Channel switch inoshanda sei?
A Fiber Channel switch chinhu chakakosha munzvimbo yekuchengetera network SAN iyo inobatsira kuendesa data nemazvo pakati pemaseva nemidziyo yekuchengetedza. Iyo switch inoshanda nekugadzira yakakwira-kumhanya yakavanzika network yakagadzirirwa kuchengetedza data uye kudzoreredza.
Pakati payo, Fiber Channel switch inotsamira pane yakasarudzika hardware uye software kubata uye kutungamira data traffic. Inoshandisa iyo Fiber Channel protocol, yakasimba uye yakavimbika yekutaurirana protocol yakagadzirirwa nharaunda dzeSAN. Sezvo data inotumirwa kubva kuvhavha kuenda kumudziyo wekuchengetedza uye zvinopesana, yakavharidzirwa muFiber Channel mafuremu, kuve nechokwadi chekuvimbika kwedata uye kufambisa-kumhanya.
Iyo SAN switch inoita semupurisa wetraffic uye inosarudza nzira yakanakisa yedata yekufamba kuburikidza neSAN. Inotarisa kwainobva uye kero dzekuenda muFiber Channel mafuremu ekufambisa kwakanaka kwemapakiti. Iyi yehungwaru nzira inodzikisira latency uye kusangana, kuve nechokwadi chekuti data inosvika kwainoenda nekukurumidza uye nekuvimbika.
Chaizvoizvo, Fiber Channel inoshandura inoronga kuyerera kwedata muSAN, inogonesa kuita uye kuvimbika munzvimbo dzinonyanya data.
3 Dzakasiyana papi?
Kuenzanisa LAN chinja kune SAN switch inogonawo kufungidzirwa sekuenzanisa chinja cheSAN kune network switch, kana Fiber Channel chinja kune Ethernet switch. Ngatitarisei misiyano mikuru pakati peLAN switch uye SAN switch.
Misiyano Yekushandisa
LAN switches yakatanga kugadzirirwa ring ring uye FDDI network uye yakazotsiviwa neEthernet. Kuchinja kweLAN kunoita basa rakakosha mukuvandudza kushanda kwese kweLANs uye kugadzirisa zvinonetsa zviripo bandwidth. MaLAN anogona kubatanidza zvigadziriso zvakasiyana siyana senge faira maseva, maprinta, dura arrays, desktops, nezvimwe, uye LAN switching inogona kunyatso gadzirisa traffic pakati peidzi magumo akasiyana.
Uye iyo SAN switch inogadzirirwa yakakwirira-inoshanda network kuti ive nechokwadi chepasi-latency uye isingarasikirwe data kutamiswa. Iyo yakanyatsogadzirwa kuti inyatso gadzirisa inorema transaction mitoro, kunyanya mune yakakwirira-inoshanda Fiber Channel network. Ingave Ethernet kana Fiber Channel, nzvimbo yekuchengetera network switch yakatsaurirwa uye yakagadziridzwa kubata kuchengetedza traffic.
Mashandiro akasiyana
Kazhinji, maLAN switch anoshandisa mhangura uye fiber interfaces uye anoshanda paIP-based Ethernet network. Layer 2 LAN switching inopa mabhenefiti ekukurumidza kuendesa data uye kushoma latency.
Iyo inokunda muzvinhu zvakaita seVoIP, QoS uye bandwidth kushuma. Layer 3 LAN switches inopa maitiro akafanana sema routers. Kana iri iyo Layer 4 LAN Switch, ishanduro yepamusoro yeLayer 3 LAN Switch inopa mamwe maapplication akadai seTelnet neFTP. Uyezve, iyo LAN Switch inotsigira mapuroteni anosanganisira asi asina kuganhurirwa kuSNMP, DHCP, Apple Talk, TCP. / IP, uye IPX. Zvose mune zvose, LAN Switch inodhura-inoshanda, iri nyore-ku-deploy networking solution iyo Yakanaka kune bhizinesi uye yepamusoro-soro inodiwa.
SAN switch inovaka pahwaro hweiSCSI kuchengetedza network, inosanganisira Fiber Channel uye iSCSI matekinoroji. Chinonyanya kukosha ndechekuti SAN switches inopa epamusoro kuchengetedza kugona pamusoro peLAN switch. Fiber Channel switch inogona zvakare kuve Ethernet switch.
Sezvineiwo, Ethernet-yakavakirwa SAN switch yaizove yakatsaurirwa kutonga yekuchengetedza traffic mukati meIP yekuchengetedza nzvimbo network, nekudaro kuve nechokwadi chekufungidzira kuita. Zvakare, nekubatanidza SAN switch, yakakura SAN network inogona kuumbwa kubatanidza akawanda maseva uye madoko ekuchengetera.
4 Ndinosarudza sei switch chaiyo?
Paunenge uchifunga nezveLAN vs. SAN, kusarudzwa kweLAN switch kana SAN switch inova yakakosha. Kana zvaunoda zvinosanganisira faira-kugovera maprotocol akadai seIPX kana AppleTalk, ipapo IP-based LAN switch ndiyo yakanakisa sarudzo yechishandiso chekuchengetedza. Sezvineiwo, kana iwe uchida switch yekutsigira Fiber Channel-yakavakirwa kuchengetedza, inetiweki nzvimbo yekuchengetedza switch inokurudzirwa.
LAN inochinja inofambisa kutaurirana mukati meLAN nekubatanidza zvishandiso mukati metiweki imwe chete.
Fiber Channel switch, kune rumwe rutivi, inonyanya kushandiswa kubatanidza zvigadziriso zvekuchengetedza kumaseva kuitira kuchengetedza kwakanaka uye kudzosa data. Aya ma switch anosiyana mumutengo, scalability, topology, chengetedzo, uye kuchengetedza kugona. Chisarudzo pakati pavo chinoenderana nezvinodiwa zvekushandisa.
Ma LAN switch haadhure uye ari nyore kugadzirisa, nepo SAN switch inodhura uye inoda mamwe magadzirirwo akaomarara.
Muchidimbu, LAN switch uye SAN switches akasiyana marudzi etiweki switch, imwe neimwe ichiita basa rakasiyana mune network.
