Gigabit Switches: Tips for ngokukhetha

Ukuphuculwa yendawo iikhompyutha womnatha lwamashishini - umsebenzi oza kungekudala nazo zonke abalawuli nkqubo. Ukuphucula computers ukuzisebenzela kweesoftwe kunye ukudala iimeko kangangoko zokusebenza sabaqeshwa elizayo kuya kukhokelela ekwandeni impumelelo yenkampani. I-unit main, intliziyo naluphi womnatha eziphuhlileyo na eyenziwayo gigabit. Zinika smooth transfer data multi-azinamsonto ze-high speed kunye uphawu eyayizalwa. Ukhetho oluchanekileyo lwe element kuxhomekeke ekusebenzeni uthungelwano kunye kwishishini liphela.

Tshintsha kunye hub

Vula - isixhobo esibonelela yeemanyano iikhompyutha eziliqela kwi LAN enye kwaye isebenza ukuphucula umgangatho uphawu ngesondo. Kanye imisebenzi efanayo yenziwa kwezinye izixhobo womnatha - njengentsika (kunye IsiNgesi Hub -. Nayiphi node kwi network). Noko ke, xa iingcali kukhethwa kudala kucetyiswa ukuba ukunika imiyalelo iiswitshi. Yintoni ebangela oku?

umsebenzi hub unokufaniswa ukuqhutywa zabaphindayo aqhelekileyo - ifumene uphawu kwaye iyithumele ukuba zonke iikhompyutha enxulumene, kungakhathaliseki ukuba yintoni na ikhompyutha eyenzelwe ukuhanjiswa kolwazi. Ngenxa yokuba i "lokuposa mass" LAN fast "ukubulawa" ezinjalo, kwanciphisa izinga ukudluliselwa xa iyonke. Ukongeza, kokukhona ukucwangcisa kweendawo kwinethiwekhi, ayanda amathuba inyanda yesaqhwithi - apho kukho inani elikhulu of iipakethi ezingaphefumlelwanga wathumela ngapha komsebenzi womnatha.

Eziqhelekileyo Gigabit sokuyivula ngoko nangoko emva kokuba uxhulumaniso akukho ezahlukeneyo ukusuka hub. Kodwa ngokuhamba kwexesha, zakha itafile ziguquka, okanye uluhlu lubekwa le Mac needilesi iikhompyutha, njengoko apho ipakethe yeenkcukacha ithunyelwa kwixesha elizayo. Ngenxa yoko, elilelona umsebenzi iyaxhaswa yinethwekhi.

Inani kumazibuko kunye nesantya

Performance LAN kuxhomekeke kwizicwangciso iswitshi. Nkqu izixhobo ifikelelekayo ezineefitsha ngaphezulu bahluka kwezinye amalungu ale nangamanani. Noko ke, xa ukhetha kufuneka sinikele ingqalelo kuphela ezinye i parameters ibalulekileyo. Eyokuqala linani zamazibuko. Oku kugqiba inani izixhobo network ezinokuthi kuqhagamshelwa iswitshi. Ngokuqhelekileyo, inani zamazibuko aguquguquka ukusuka-5 ukuya 48. Enye parameter obalulekileyo umyinge data - isantya apho nganye isebenza gigabit lezibuko iswitshi. Kwimeko lethu ayikho ngaphantsi kwe 1000 MB / umzuzwana. Kodwa kwezixhobo ezininzi sixhasa IEEE 802,3 Nway - rate ipakethe auto-ubhaqo.

umthamo

Bandwidth - imveliso inani namazibuko ngenqanaba data eliphezulu. Le parameter kugqiba ukusebenza kwenkqubo ngalo mzuzu kombane. Ngeyona ndlela inenzuzo enkulu, eli nani liya kuba phezulu, umsinga data ukuva zonke iiPC ngexesha elifanayo. Umzekelo, switsha wakho uye mazibuko-10 ngesantya ukuya ku 300 Mb / s. umthamo wayo 2 GB / s. Ngexesha nencopho amazibuko umthwalo uya kukwazi ukuba adlulisele ukungena kolwazi-3 Gb / s, nto leyo lingaphantsi bandwidth. Ezi itshintshela Gigabit akayi kuba nako ukumelana nemfuno incopho kwaye kuthintele umsebenzi lweshishini lonke.

ukusebenza Network kuxhomekeke lulungelelaniso Full-kabini kunye Half-engayi. Kwimo Full-kabini, ukuba ukudluliselwa iipakethi data kuthatha ngaxeshanye indawo kumacala amabini - ukusuka switsha kwi khompyutha kunye vice versa. Imowdi Half-kabini, uphawu usasazwa ugqithiselwa kuphela kwicala elinye. Eyakhelwe-abafanayo ukuthintela ukubethabethana ngexesha nokusebenza kwezixhobo womnatha usebenzisa iindlela ezahlukeneyo.

Gxininisa

Xa kukhethwa ukuzitshintshela ebalulekileyo ukuba banikele ingqalelo ubungakanani kwetafile ziguquka enxulumene "magama" izibuko kwidilesi Mac ye computer. Olu khetho kuyimfuneko ukuze kube nokugqitywa kunye nenani iiPC kumsebenzi womnatha wakho. Kwiimeko apho izixhobo memory kuya kubakho igumbi emazishicilelwe isixhobo esitsha womnatha, iya ukususa idilesi ye-PC esetyenzisiweyo engafane, uze uphinde-iqala uphendlo lwayo. Oku kunciphisa kakhulu yokusebenza.

Flow Control osemqoka kufuneka abe zonke iiswitshi gigabit, kuba inika ukhuseleko ekulahlekelweni data. Ngoncedo yamacebo ezimbini ukuya 'thethana "phakathi kwabo, apho ukuze naxa ukuthumela uphawu.

ulawulo switch

Ngokutsho uhlobo itshintshela zolawulo zahlulwe iindidi ezimbini - ilawulwe olungalawulwayo. Kwimeko yokuqala esinayo isixhobo elizenzekelayo ngokupheleleyo ngaphandle utshintsho izixhobo ncwadana ekulinganisweni. It ifanele khulu ofisi encinane okanye Inetweki yekhaya, kuba sele ngendleko ephantsi, akunyanzelekanga ukuba ungenelelo yabantu. main ethile Its - kwemveliso phantsi, nto leyo akavumeli ukusetyenziswa kwayo inkampani enkulu. Aphethwe Gigabit Tshintsha kwakhona imisebenzi kwimo oluzenzekelayo, kodwa uluhlu olubanzi lwezixhobo ngayo umphathi wekhomputha ukunyenyisa umsebenzi wakhe ngaphandle kobunzima. abameli kamabonwakude ke JetStream, TP-Link, D-Link. abaphumeleli yabo ebonakalayo - ixabiso eliphezulu.

10 eyenziwayo gigabit

Ngokhuphiswano kubalulekile kakhulu ukuba bakwazi ukwenza izigqibo ngokukhawuleza nokunika imiyalelo. Ukuze oku kwenzeke, kufuneka kukuxhobisa loshishino kunye itshintshela ngesantya esiphezulu ezibonelela ukudluliselwa data ngamaxabiso ukuya ku-10 Gb / s. Kuthiwa ukuba kukho izixhobo ezinjalo kummandla wentengiso iminyaka engaphezu kwama-10 eyadlulayo. Noko ke, bathi cwaka ezifanelekileyo, siyiguqulela ayifumanekanga okwangoku.

To connect ukuzitshintshela gigabit-10, ungasebenzisa ifayibha optic cable, twinax okanye abaqhelekileyo ucingo lobhedu standard UTP / FTP. Namhlanje, ethandwa kakhulu zizixhobo adibanayo ucingo lobhedu oluqhelekileyo. Zinika idatha kwi technology 10GBASE-T, kufuneka ngexabiso eliphantsi kwaye wenze le network kangangoko bhetyebhetye kangangoko kunokwenzeka. Ngokwahlukeneyo, kubalulekile ukukhumbula ngezisebenzelwanoezibuya umva kunye uthungelwano Gigabit.

abathengisi shintsha

Ivula kuluhlu lwethu yenkampani Alcatel-Lucent. usapho lwayo OmniSwitch yezixhobo yenzelwe ukwakhiwa medium and enkulu, kwakunye nefowuni networks engundoqo kwamashishini amancinane. Le modeli OmniSwitch 6850E ziyavela Gigabit-10 sivula luyafumaneka njengento extra, kodwa OmniSwitch 6900 uye wakha 64 amazibuko ye-high speed transmission ipakethe.

Company D-Link linoluhlu abameli ababini kuphela kolu didi kwezixhobo. Yakhe 8-Port Gigabit Desktop Switch DXS-3600-16S inika sokudityaniswa PC nge isibuko esingatshintshiyo SFP +, kodwa imodeli DXS-3600-32S sele 24 isinxibelelanisi efanayo. Zombini ezi zixhobo kufuneka isihlalo lomnqongo ukwanda, apho aya kuba nako ukudibanisa kwinethiwekhi ubugcisa 10GBASE-T.

inkampani Cisco akakwazi ukumkholisa izixhobo ngokupheleleyo. Noko ke, inikeza isisombululo iindleko-ngempumelelo ngakumbi ngohlobo iimodyuli Plug-in, umzekelo, Nexus kunye kuvala. Ezi "Izandiso" zingasetyenziswa ukudibanisa kumsebenzi womnatha nokuba intambo sobhedu okanye nge ifayibha optical.

HP linika itshintshela yayo Gigabit iimfuno zamashishini ezincinane kunye neziphakathi. Enye abameli ezigqamileyo yi HP 6125G / XG, nto leyo isixhobo gqith '- 1 gigabit-10 / iswitshi. Kuphela gigabit-10 imifuziselo utshintsho series thaca 5820. Bahlala kulo yesantya izihlalo SFP +. Noko ke, phakathi izixhobo ingafunyanwa, kunye PoE-gigabit utshintsho Industrial HP 5920 series.

Yintoni azikhethele inethiwekhi yakho yasekhaya?

Ukuba usebenzisa udibaniso engenazingcingo yokudibanisa izixhobo kwinethiwekhi yasekhaya ayinakwenzeka okanye ayamkelekanga ngenxa yezinga data aphantsi, kuya kuba kuhle ukuba ukusebenzisa eyenziwayo olungalawulwayo. Okokuqala, ukuba abiza. Okwesibini, kulula ukuqhagamshelana uqwalasele, akunyanzelekanga ukuba ungenelelo umsebenzisi. Ukhetho osenyongweni uza kuba imodeli TP-LINK TL-SG1008D. Iswitshi iye mazibuko 8 yoqhagamshelo, imisebenzi licandelo umbane iqhagamshele iplagi. transmission Data nakanjani ngesantya 1 Gb / s.

uyakwazi ukukhetha i Gigabit TRENDnet okanye Asus utshintsho imveliso enombala uma oyifunayo. Yeendleko zezi zixhobo zikwinqanaba elamkelekileyo, kunye nokusebenza babo entloko ngokwaneleyo ukuhlangabezana neemfuno kwinethiwekhi yasekhaya.
