Kev nyiam tshaj Optics rau Arista 7250QX-64
Yuav kom ua tau raws li qhov kev xav tau ntawm kev loj hlob zuj zus 10 thiab 40 Gigabit Ethernet, Arista qhib lub 7250X Series keyboards los pab txhawb kev sib txuam nrog 10G thiab 40 G nyob rau hauv ib qho kev sib tw ua kom haum rau cov qauv ntawm sab hnub tuaj-sab hnub poob thiab txhawb qhov yuav tsum tau rau cov uas tsis muaj latency thiab cov hluav taws xob ua haujlwm nyob rau hauv cov neeg ua hauj lwm ntom zom. Ntawm qhov 7250X Series, qhov kev hloov Arist 7250QX-64 tau txais kev pom zoo los ntawm ntau tus neeg siv tshuab Ethernet vim nws tsis muaj latency, muaj hluav taws xob ua haujlwm thiab kev ua haujlwm siab. Cov ncauj lus kom ntxaws txog Ariston 7250QX-64 thiab nws cov twj siv tau tshaj li ntawm mas yuav tau them rau hauv cov lus hauv qab no.
Cov Ariste 7250QX-64 muab cov qis tsis zoo, thiab ib qho kev sib tw packet tsis sib tw ntawm 12MB ib pawg ntawm cov chaw nres nkoj uas muab faib mus rau cov chaw nres nkoj uas muaj congested. Nrog 64 QSFP + ports lub 7250QX-64 yog tuab 40GbE los yog 256 × 10GbE ntawm xaim ceev kev ua haujlwm hauv 2RU. Nov yog qee qhov tseem ceeb ntawm txoj kev hloov no:
Built-in cia.
Resilient tswj dav hlau.
Huab tshua txog kev npaj.
Cov ntaub ntawv tsim kho qhov chaw nruab nrab.
Daim duab saum toj no qhia tias Ariste 7250QX-64 hloov qhov 64 QSFP + cov chaw nres nkoj txhawb kev 64 × 40GbE los yog 256 × 10GbE.
Tus Aristx 7250QX-64 txhawb kev sib tw ntawm 10 thiab 40 Gigabit Ethernet connectivity options. Cov chaw nres nkoj 10G / 40G txhawb qhov kev txhim kho ntawm SFP + thiab QSFP +.
Los ntawm cov lus hais saum toj no, peb paub tseeb hais tias qhov kev hloov ntawm Ariston 7250QX-64 muaj 64 QSFP + cov chaw nres nkoj, yog li koj tuaj yeem ncaj qha mus "hloov tau" ntawm ob hnub ntawm DAC cables mus rau qhov chaw nres nkoj. Rau kis nrug luv luv nrug, koj tuaj yeem xaiv 40G QSFP + DAC cables ua network txuas. Los ntawm kev siv 40G breakout cable, koj tuaj yeem ntsaws qhov kawg ntawm 40G QSFP + tooj xa ncaj txuas rau hauv 40G QSFP + cov chaw nres nkoj thiab ntsaws lwm hnub ntawm DAC lub xov tooj mus rau plaub 10G SFP + cov chaw nres nkoj. Dhau li, koj tuaj yeem xa ob hnub ntawm 40G QSFP + DAC cable nrog 40G QSFP + cov chaw nres nkoj ncaj qha kom ua kev sib txuas ntawm Ariston 7250QX-64. Thaum kis tau tus mob dua, 40G QSFP + AOC cable yog qhov zoo rau kev hloov cov ntaub ntawv. Ib yam li lub xov tooj 40G QSFP + DAC, koj tuaj yeem txuas ob hnub ntawm 40G QSFP + AOC cable mus rau QSFP + cov chaw nres nkoj ntawm Ariston 7250QX-64. Cov 40G QSFP + DAC thiab AOC cables yog tsim rau luv nrug thiab zoo tagnrho rau kev siv nyiaj txig rau kev siv nyiaj rau koj qhov kev hloov Arist 7250QX-64.
Raws li peb pom los ntawm daim duab saum toj no, muaj ntau yam 40G QSFP + cov khoom siv rau kev hloov mus rau Arista 7250QX-64. Los ntawm kev siv 40GBASE-SR4 QSFP + transceiver, qhov siab tshaj plaws yuav mus txog 40 km ntawm ib hom fiber ntau ntawm tus tes hloov. Los ntawm 40GBASE-XSR4 QSFP + module, txuas ntev ntawm 7250QX-64 hloov tuaj txog 300 m thiab 400 m, ntsig txog, ntawm OM3 laser-optimized thiab OM4 multimode fibers.
Tus Arista 7250QX-64 yog tsim los kom muaj kev kub siab, qis tsis yooj yim thiab muaj hwj chim ua tau zoo, uas muab kev daws zoo dua rau 10G / 40G Ethernet network txuas.
