Kod\u0117l rinkausi b\u016btent \u0161\u012f model\u012f:
\n* Tinkamas fizinis plotis su 16’lika gigabitini\u0173 port\u0173
\n* Rack mount
\n* Indikaciniai LED yra priekyje t.y. toje pa\u010dioje pus\u0117je kaip ir fizin\u0117s jungtys
\n* Maitinimo blokelis \u012fmontuotas korpuse tod\u0117l maitinimo laidas jungiamas tiesiai \u012f korpus\u0105
\n* Nugaroje turi \u012fjungimo\/i\u0161jungimo mygtuk\u0105. Jei kada reiks perkrauti nereik\u0117s i\u0161traukin\u0117ti maitinimo laido.<\/p>\n
Statybos metu statytojai suved\u017eiojo tikrai ne brangiausia UTP kabel\u012f, kuris, jei gerai pamenu, net neturi ekrano. Kabeliai suved\u017eioti kartu su maitinimo\/ap\u0161vietimo kabeliais. UTP panel\u0117 C5e kuri taip pat n\u0117ra skirta gigabitiniam tinklui. Patch kabeliukai patys papra\u0161\u010diausi, pigesni\u0173 turb\u016bt rasti ne\u012fmanoma (\u0161itai a\u0161 \u017eadu i\u0161taisyti).<\/p>\n
Tad pamatuokime tinklo greiti. Matuosime su iperf<\/em>.<\/p>\n Savo staliniam kompiuteryje kurio IP adresas yra 192.168.0.101 paleid\u017eiu servis\u0105:<\/p>\n Pradedam greit\u012f matuoti nuo l\u0117\u010diausi\u0173 klient\u0173. Raspberry pi<\/em> kurio LAN interfeisas yra pajungtas per USB2 magistral\u0119 ir jei \u0161is techninis nesusipratimas nebus sutvarkytas aviet\u0117 niekad netur\u0117s galimyb\u0117s kominikuoti grei\u010diau (ta pati problema su vis\u0173 modeli\u0173 aviet\u0117mis).<\/p>\n Sekantis bandymas su Banana pi<\/em>. Pastarasis kompiuteriukas jau turi 1Gbs interfeis\u0105. Beje jis turi ir SATA jungt\u012f tad realus duomen\u0173 ra\u0161ymas kopijuojant duomenis jau atsirems \u012f disko galimybes, ne \u012f LAN interfeiso.<\/p>\n >500Mbs yra daugia nei gana tokiam kompiuteriukui.<\/p>\n Na ir paskutinis bandymas, ne\u0161iojamas HP 450 G1<\/em> pajungtas per 1Gbs interfeis\u0105:<\/p>\n Kaip su auk\u0161\u010diau min\u0117tomis technin\u0117mis s\u0105lygomis, manau >900Mbs yra tikrai geras greitis. Ir klausimas ar su tikrai gerais kabeliais greitis labai priart\u0117tu prie 1000Mbs.<\/p>\n","protected":false},"excerpt":{"rendered":" Besibeld\u017eiant 2018 pagalvojau, kad pats laikas namuose 100Mbs tinkl\u0105 atnaujinti iki 1Gbs tuo labiau, kad mano naudojamas 8 port\u0173 switch’iukas (komutatorius) tapo per ank\u0161tas.
