Ukukhetha iswitshi yenethiwekhi elungileyo kubalulekile xa kusakha inethiwekhi eyomeleleyo nesebenzayo. I-network switch isebenza njenge-hub ephakathi, idibanisa izixhobo ezahlukeneyo ngaphakathi kwenethiwekhi yendawo yendawo (LAN) kwaye ibenza bakwazi ukunxibelelana omnye nomnye. Ngeenketho ezininzi kwimarike, ukukhetha iswitshi elungileyo kunokuba nzima. Nazi izinto ezintlanu ezibalulekileyo ekufuneka uzijonge kutshintsho lwenethiwekhi ukuze uqinisekise ukusebenza kakuhle kunye nokusebenza.
1. Inkxaso yeVLAN
Inkxaso yeNgcaciso yeNgingqi yeNgingqi (VLAN) yinkalo ephambili yalo naluphi na utshintsho lwenethiwekhi yanamhlanje. Ii-VLANs zikuvumela ukuba uhlukanise inethiwekhi yakho ibe ngamaqela ahlukeneyo anengqondo, okonyusa ukhuseleko kunye nokuphucula ukusebenza. Ngokuhlukanisa i-traffic, ii-VLAN zinokunciphisa ukuxinana kwaye ziqinisekise ukuba ngabasebenzisi abagunyazisiweyo kuphela abanokufikelela kwidatha ebuthathaka. Xa ukhetha ukutshintshwa kwenethiwekhi, qiniseka ukuba ixhasa i-VLAN tagging (802.1Q) ukuququzelela le nxalenye. Eli nqaku liluncedo kakhulu kumashishini afuna amasebe ahlukeneyo ukuba abe nothungelwano oluzimeleyo kodwa abelane ngeziseko ezingundoqo ezifanayo.
2. Inani lamazibuko
Inani lezibuko kwiinethiwekhi yokutshintshayenye into ebalulekileyo ekufuneka iqwalaselwe. Inani lamazibuko limisela inani lezixhobo ezinokuqhagamshelwa kwiswitshi ngexesha elinye. Kwiofisi encinci okanye inethiwekhi yasekhaya, ukutshintshela kunye ne-8 ukuya kwi-16 izibuko kunokwanela. Nangona kunjalo, imibutho emikhulu okanye abo balindele ukukhula kufuneka bathathele ingqalelo utshintsho olune-24, 48, okanye nangaphezulu. Kwakhona, khangela iitshintshi ezinikezela ngeentlobo ezahlukeneyo zezibuko, ezifana ne-Gigabit Ethernet kunye ne-SFP (i-Small Form Factor Pluggable) izibuko, ukulungiselela izixhobo ezahlukeneyo kunye neemfuno zokwandiswa kwexesha elizayo.
Inkxaso ye-3.PoE
Amandla phezu kwe-Ethernet (i-PoE) inkxaso yinto eyandayo eyaziwayo kwiiswitshi zenethiwekhi. I-PoE ivumela iintambo zenethiwekhi ukuba zithwale zombini idatha kunye namandla, ukuphelisa imfuno yokunikezelwa kombane okwahlukileyo kwizixhobo ezifana neekhamera ze-IP, iifowuni zeVoIP, kunye neendawo zokungena ezingenazintambo. Olu phawu lwenza lula ufakelo kwaye lunciphise i-clutter, luyenze ibe lukhetho olukhulu kumashishini ajonge ukwenza lula ukuseta inethiwekhi yawo. Xa ukhetha iswitshi, khangela uhlahlo lwabiwo-mali lwe-PoE ukuqinisekisa ukuba inokuxhasa iimfuno zamandla zizonke zazo zonke izixhobo ezixhunyiwe.
4. Isantya sothungelwano
Isantya sothungelwano ngumba osisiseko walo naluphi na utshintsho lwenethiwekhi. Isantya sogqithiso lwedatha sinokuchaphazela kakhulu ukusebenza ngokubanzi kwenethiwekhi. Khangela iiswitshi ezixhasa ubuncinci i-Gigabit Ethernet (1 Gbps) ukuze usebenze ngokufanelekileyo kwiindawo ezininzi. Kwimibutho eneemfuno eziphezulu ze-bandwidth, ezifana nalezo zisebenzisa i-conferencing yevidiyo okanye ukuhanjiswa kweefayile ezinkulu, qwalasela utshintsho olunikezela nge-10 Gbps okanye isantya esiphezulu. Kwakhona, qiniseka ukuba iswitshi inomthamo owaneleyo we-backplane ukuze uphathe ukutyhubela okudityanisiweyo kuwo onke amazibuko ngaphandle kokuphazamiseka.
5. Ukugcinwa kunye nokungabikho kogcino
Okokugqibela, qwalasela ukuba ufuna isitshixo sothungelwano esilawulwayo okanye esingalawulwayo. Iiswitshi ezingalawulwayo zizixhobo zeplagi kunye nokudlala ezingadingi uqwalaselo, zizenza zilungele uthungelwano olulula. Nangona kunjalo, ukuba ufuna ukulawula ngakumbi kwinethiwekhi yakho, iswitshi elawulwayo lolona khetho lulungileyo. Iiswitshi ezilawulwayo zibonelela ngeempawu eziphambili ezifana nokubeka iliso kwi-traffic, ukucwangciswa kweVLAN, kunye neseto loMgangatho weNkonzo (QoS), okuvumela ukuguquguquka okukhulu kunye nokulungiswa kokusebenza kwenethiwekhi. Ngelixa utshintsho olulawulwayo luthanda ukubiza kakhulu, izibonelelo abazinikezelayo zinokuxabiseka kuthungelwano olukhulu okanye oluntsokothileyo.
ukuququmbela
Ukukhetha okulungileyoinethiwekhi yokutshintshaKubalulekile ukuqinisekisa ukuba inethiwekhi yakho ithembekile kwaye iyasebenza. Ngokuqwalasela iimpawu ezifana nenkxaso ye-VLAN, inani lamachweba, inkxaso ye-PoE, isivinini sothungelwano, kunye nokuba ukhetha ukutshintshela okulawulwayo okanye okungalawulwayo, unokwenza isigqibo esinolwazi oluhlangabezana neemfuno zakho ezithile. Utyalo-mali kutshintshiselwano olusemgangathweni aluyi kuphucula kuphela ukusebenza kwenethiwekhi yakho yangoku, kodwa ikwabonelela nge-scalability oyifunayo ekukhuleni kwexesha elizayo.
