Tam sim no, feem ntau cov lag luam network thiab cov ntaub ntawv chaw cov neeg siv tau txais QSFP + rau SFP + chaw nres nkoj breakout splitting tswvyim los txhim kho 10G network uas twb muaj lawm rau 40G network tau zoo thiab ruaj khov kom tau raws li qhov xav tau ntawm kev sib kis ceev.Qhov no 40G rau 10G chaw nres nkoj splitting tswvyim tuaj yeem siv tag nrho cov khoom siv network uas twb muaj lawm, pab cov neeg siv txuag nqi, thiab ua kom yooj yim rau kev teeb tsa network.Yog li yuav ua li cas thiaj ua tiav 40G rau 10G kis tau tus mob?Kab lus no yuav qhia peb txoj kev sib cais los pab koj ua tiav 40G rau 10G kis tau tus mob.
Qhov Chaw nres nkoj Breakout yog dab tsi?
Breakouts pab kev sib txuas ntawm cov khoom siv hauv network nrog cov chaw nres nkoj sib txawv, thaum siv cov chaw nres nkoj bandwidth tag nrho.
Breakout hom ntawm cov cuab yeej siv network (switches, routers, thiab servers) qhib txoj hauv kev tshiab rau cov neeg ua haujlwm hauv network kom ua raws li qhov xav tau ntawm bandwidth.Los ntawm kev ntxiv cov chaw nres nkoj siab ceev uas txhawb kev tawg, cov neeg ua haujlwm tuaj yeem ua kom lub ntsej muag qhov chaw nres nkoj ceev thiab pab kom hloov mus rau cov ntaub ntawv ntau dua ntxiv.
Kev ceev faj rau kev sib cais 40G rau 10G Ports Breakout
Feem ntau cov keyboards hauv kev ua lag luam txhawb nqa chaw nres nkoj splitting.Koj tuaj yeem tshawb xyuas seb koj lub cuab yeej puas txhawb nqa chaw nres nkoj los ntawm kev xa mus rau cov khoom siv hloov pauv lossis nug tus neeg muag khoom.Nco ntsoov tias hauv qee qhov tshwj xeeb, hloov chaw nres nkoj tsis tuaj yeem muab faib.Piv txwv li, thaum qhov hloov pauv ua raws li nplooj hloov pauv, qee qhov ntawm nws cov chaw nres nkoj tsis txhawb qhov chaw nres nkoj;Yog tias qhov chaw nres nkoj hloov ua haujlwm ua ib qho chaw nres nkoj, qhov chaw nres nkoj tsis tuaj yeem faib.
Thaum faib qhov chaw nres nkoj 40 Gbit / s rau hauv 4 x 10 Gbit / s chaw nres nkoj, xyuas kom meej tias qhov chaw nres nkoj khiav 40 Gbit / s los ntawm lub neej ntawd thiab tsis muaj lwm yam L2 / L3 ua haujlwm tau qhib.Nco ntsoov tias thaum lub sijhawm txheej txheem no, qhov chaw nres nkoj tseem khiav ntawm 40Gbps kom txog thaum lub kaw lus rov pib dua.Yog li ntawd, tom qab sib faib 40 Gbit / s chaw nres nkoj rau hauv 4 x 10 Gbit / s chaw nres nkoj siv CLI hais kom ua, rov pib lub cuab yeej kom ua rau cov lus txib siv tau.
QSFP + rau SFP + Cable Scheme
Tam sim no, QSFP + rau SFP + kev sib txuas schemes feem ntau suav nrog cov hauv qab no:
QSFP + rau 4 * SFP + DAC / AOC Direct Cable Connection Scheme
Txawm hais tias koj xaiv 40G QSFP + rau 4 * 10G SFP + DAC tooj liab core high-speed cable lossis 40G QSFP + rau 4 * 10G SFP + AOC active cable, kev sib txuas yuav zoo ib yam vim DAC thiab AOC cable zoo sib xws hauv kev tsim thiab lub hom phiaj.Raws li pom hauv daim duab hauv qab no, ib kawg ntawm DAC thiab AOC ncaj qha cable yog 40G QSFP + txuas, thiab lwm qhov kawg yog plaub cais 10G SFP + txuas.QSFP + txuas txuas ncaj qha rau hauv QSFP + chaw nres nkoj ntawm qhov hloov pauv thiab muaj plaub qhov sib npaug ntawm cov kab sib txuas, txhua tus ua haujlwm ntawm tus nqi txog 10Gbps.Txij li thaum DAC high-speed cables siv tooj liab thiab AOC active cables siv fiber ntau, lawv kuj txhawb kev sib kis sib txawv.Feem ntau, DAC high-speed cables muaj luv dua kis tau tus mob.Qhov no yog qhov sib txawv tshaj plaws ntawm ob.
Hauv 40G rau 10G kev sib cais, koj tuaj yeem siv 40G QSFP + rau 4 * 10G SFP + ncaj qha kev txuas cable txuas mus rau qhov hloov pauv yam tsis tas yuav cov khoom siv kho qhov muag ntxiv, txuag nqi network thiab ua kom yooj yim rau txoj kev sib txuas.Txawm li cas los xij, qhov kev ncua deb ntawm qhov kev sib txuas yog txwv (DAC≤10m, AOC≤100m).Yog li ntawd, ncaj qha DAC lossis AOC cable yog qhov tsim nyog rau kev txuas lub txee lossis ob lub txee uas nyob ib sab.
40G QSFP + rau 4 * LC Duplex AOC Ceg Active Cable
Lub 40G QSFP + rau 4 * LC duplex AOC ceg active cable yog ib hom tshwj xeeb ntawm AOC nquag cable nrog QSFP + txuas ntawm ib kawg thiab plaub cais LC duplex jumpers ntawm lwm qhov.Yog tias koj npaj yuav siv 40G rau 10G active cable, koj xav tau plaub SFP + optical modules, uas yog, QSFP + interface ntawm 40G QSFP + rau 4 * LC duplex active cable tuaj yeem ncaj qha tso rau hauv 40G chaw nres nkoj ntawm lub cuab yeej, thiab LC interface yuav tsum tau muab tso rau hauv qhov sib thooj 10G SFP + optical module ntawm lub cuab yeej.Txij li thaum feem ntau cov khoom siv sib xws nrog LC interfaces, hom kev sib txuas no tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv feem ntau.
MTP-4 * LC Ceg Optical Fiber Jumper
Raws li pom hauv daim duab hauv qab no, ib kawg ntawm MTP-4 * LC ceg jumper yog 8-core MTP interface rau txuas rau 40G QSFP + optical modules, thiab lwm qhov kawg yog plaub duplex LC jumpers rau txuas rau plaub 10G SFP + optical modules .Txhua kab xa cov ntaub ntawv ntawm tus nqi ntawm 10Gbps kom tiav 40G rau 10G kis tau tus mob.Qhov kev daws teeb meem kev sib txuas no yog tsim rau 40G high-density networks.MTP-4 * LC ceg jumpers tuaj yeem txhawb nqa cov ntaub ntawv txuas mus ntev piv rau DAC lossis AOC txuas ncaj qha cables.Txij li feem ntau cov khoom siv tau sib xws nrog LC interfaces, MTP-4 * LC ceg jumper kev sib txuas tswv yim tuaj yeem muab cov neeg siv nrog cov txheej txheem xaim yooj yim dua.
Yuav Ua Li Cas Breakout 40G rau hauv 4 * 10G ntawm pebMylinking™ Network Packet Broker ML-NPB-3210+ ?
Siv piv txwv: Nco ntsoov: Txhawm rau kom muaj nuj nqis ntawm qhov chaw nres nkoj 40G ntawm Command Line, xav rov pib lub cuab yeej
Txhawm rau nkag mus rau CLI kev teeb tsa hom, nkag mus rau hauv lub cuab yeej los ntawm qhov chaw nres nkoj serial lossis SSH Telnet.Khiav "pab---configure lub davhlau ya nyob twg---interface ce0---ceev 40000---tawg tawm"cov lus txib hauv ib ntu los pab kom CE0 chaw nres nkoj breakout muaj nuj nqi.Thaum kawg, rov pib lub cuab yeej raws li tau hais tseg.Tom qab rov pib dua, cov cuab yeej siv tau ib txwm siv.
Tom qab lub cuab yeej rov pib dua, 40G chaw nres nkoj CE0 tau tawg mus rau hauv 4 * 10GE chaw nres nkoj CE0.0, CE0.1, CE0.2, thiab CE0.3.Cov chaw nres nkoj no tau teeb tsa cais raws li lwm qhov chaw nres nkoj 10GE.
Piv txwv li kev pab cuam: yog los pab kom lub breakout muaj nuj nqi ntawm 40G chaw nres nkoj ntawm kab hais kom ua, thiab breakout 40G chaw nres nkoj mus rau plaub 10G ports, uas yuav configured nyias raws li lwm yam 10G ports.
Breakout Advantages thiab Disadvantages
Qhov zoo ntawm breakout:
● Qhov ceev dua.Piv txwv li, 36-chaw nres nkoj QDD breakout hloov tuaj yeem muab peb qhov ceev ntawm qhov hloov nrog ib txoj kab downlink ports.Yog li ua tiav tib tus naj npawb ntawm cov kev sib txuas siv tsawg dua ntawm cov keyboards.
● Kev nkag mus rau kev sib cuam tshuam qis dua.Piv txwv li, QSFP-4X10G-LR-S transceiver enables hloov nrog QSFP ports nkaus xwb los txuas 4x 10G LR interfaces rau ib qhov chaw nres nkoj.
● Kev txuag nyiaj txiag.Vim qhov xav tau tsawg dua rau cov khoom siv xws li chassis, phaib, cov khoom siv fais fab, kiv cua,…
Disadvantages ntawm breakout:
● Cov tswv yim hloov nyuaj dua.Thaum ib qho ntawm cov chaw nres nkoj ntawm lub transceiver breakout, AOC lossis DAC, mus tsis zoo, nws yuav tsum tau hloov tag nrho cov transceiver lossis cable.
● Tsis yog customizable.Hauv cov keyboards nrog ib txoj kab downlinks, txhua qhov chaw nres nkoj tau teeb tsa tus kheej.Piv txwv li, ib qho chaw nres nkoj ib tus neeg tuaj yeem yog 10G, 25G, lossis 50G thiab tuaj yeem txais txhua hom kev hloov pauv, AOC lossis DAC.QSFP-tsuas yog chaw nres nkoj hauv hom breakout yuav tsum muaj kev sib koom ua ke, qhov twg txhua qhov kev sib txuas ntawm lub transceiver lossis cable yog tib hom.
