Tam sim no, feem ntau cov neeg siv network thiab cov chaw khaws ntaub ntawv siv QSFP + rau SFP + qhov chaw nres nkoj tawg los txhim kho lub network 10G uas twb muaj lawm mus rau 40G network kom zoo thiab ruaj khov kom tau raws li qhov xav tau ntawm kev xa xov ceev ceev. Qhov kev faib chaw nres nkoj 40G rau 10G no tuaj yeem siv tag nrho cov khoom siv network uas twb muaj lawm, pab cov neeg siv txuag cov nqi, thiab ua kom yooj yim rau kev teeb tsa network. Yog li yuav ua li cas thiaj ua tiav kev xa xov 40G rau 10G? Tsab xov xwm no yuav qhia peb txoj kev faib los pab koj ua tiav kev xa xov 40G rau 10G.
Qhov Chaw Nres Nkoj Breakout yog dab tsi?
Kev tawg ua rau muaj kev sib txuas ntawm cov khoom siv network nrog cov chaw nres nkoj ceev sib txawv, thaum siv tag nrho cov chaw nres nkoj bandwidth.
Hom Breakout ntawm cov khoom siv network (switches, routers, thiab servers) qhib txoj hauv kev tshiab rau cov neeg teb xov tooj network kom ua raws li qhov kev thov bandwidth. Los ntawm kev ntxiv cov chaw nres nkoj ceev ceev uas txhawb nqa breakout, cov neeg teb xov tooj tuaj yeem ua rau qhov ceev ntawm qhov chaw nres nkoj ntawm lub ntsej muag thiab ua kom muaj kev hloov kho mus rau cov nqi ntaub ntawv siab dua.
Cov kev ceev faj rau kev faib 40G rau 10G Ports Breakout
Feem ntau cov keyboards hauv kev ua lag luam txhawb nqa kev faib chaw nres nkoj. Koj tuaj yeem tshawb xyuas seb koj lub cuab yeej puas txhawb nqa kev faib chaw nres nkoj los ntawm kev xa mus rau phau ntawv qhia khoom siv hloov lossis nug tus neeg muag khoom. Nco ntsoov tias qee qhov xwm txheej tshwj xeeb, cov chaw nres nkoj hloov tsis tuaj yeem faib tau. Piv txwv li, thaum lub switch ua haujlwm ua Leaf switch, qee qhov ntawm nws cov chaw nres nkoj tsis txhawb nqa kev faib chaw nres nkoj; Yog tias qhov chaw nres nkoj hloov ua haujlwm ua chaw nres nkoj sib dhos, qhov chaw nres nkoj tsis tuaj yeem faib tau.
Thaum faib qhov chaw nres nkoj 40 Gbit/s ua 4 x 10 Gbit/s, xyuas kom meej tias qhov chaw nres nkoj khiav 40 Gbit/s los ntawm lub neej ntawd thiab tsis muaj lwm yam haujlwm L2/L3 qhib. Nco ntsoov tias thaum lub sijhawm no, qhov chaw nres nkoj txuas ntxiv khiav ntawm 40Gbps kom txog thaum lub kaw lus rov pib dua. Yog li ntawd, tom qab faib qhov chaw nres nkoj 40 Gbit/s ua 4 x 10 Gbit/s siv cov lus txib CLI, rov pib dua lub cuab yeej kom cov lus txib ua haujlwm.
QSFP + rau SFP + Cabling Scheme
Tam sim no, QSFP + rau SFP + kev sib txuas feem ntau suav nrog cov hauv qab no:
QSFP + rau 4 * SFP + DAC / AOC Direct Cable Connection Scheme
Txawm koj xaiv 40G QSFP + rau 4 * 10G SFP + DAC tooj liab tub ntxhais high-speed cable lossis 40G QSFP + rau 4 * 10G SFP + AOC active cable, qhov kev sib txuas yuav zoo ib yam vim tias 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 + connector, thiab lwm qhov kawg yog plaub cais 10G SFP + connectors. QSFP + connector ntsaws ncaj qha rau hauv QSFP + chaw nres nkoj ntawm qhov hloov thiab muaj plaub parallel bidirectional channels, txhua tus ua haujlwm ntawm tus nqi txog li 10Gbps. Txij li thaum DAC high-speed cables siv tooj liab thiab AOC active cables siv fiber, lawv kuj txhawb nqa qhov sib txawv kis. Feem ntau, DAC high-speed cables muaj qhov sib txawv kis luv dua. Qhov no yog qhov sib txawv pom tseeb tshaj plaws ntawm ob.
Hauv kev sib txuas 40G txog 10G sib cais, koj tuaj yeem siv 40G QSFP + rau 4 * 10G SFP + txuas ncaj qha cable los txuas rau lub qhov hloov pauv yam tsis tas yuav yuav cov khoom siv kho qhov muag ntxiv, txuag cov nqi network thiab ua kom yooj yim rau cov txheej txheem sib txuas. Txawm li cas los xij, qhov kev sib kis ntawm qhov kev sib txuas no txwv (DAC ≤ 10m, AOC ≤ 100m). Yog li ntawd, DAC lossis AOC cable ncaj qha yog qhov tsim nyog dua rau kev txuas lub txee lossis ob lub txee sib ze.
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 active cable nrog QSFP + connector ntawm ib kawg thiab plaub cais LC duplex jumpers ntawm qhov tod tes. Yog tias koj npaj 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 ntxig ncaj qha rau hauv 40G chaw nres nkoj ntawm lub cuab yeej, thiab LC interface yuav tsum tau ntxig rau hauv 10G SFP + optical module ntawm lub cuab yeej. Vim tias 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 feem ntau cov neeg siv.
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 kev txuas rau 40G QSFP + optical modules, thiab lwm qhov kawg yog plaub duplex LC jumpers rau kev txuas rau plaub 10G SFP + optical modules. Txhua kab xa cov ntaub ntawv ntawm tus nqi ntawm 10Gbps kom ua tiav qhov kev xa xov 40G rau 10G. 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 kev xa cov ntaub ntawv deb piv rau DAC lossis AOC ncaj qha txuas cables. Vim tias feem ntau cov khoom siv sib xws nrog LC interfaces, MTP-4 * LC ceg jumper kev sib txuas scheme tuaj yeem muab cov neeg siv nrog cov qauv hluav taws xob yooj ywm dua.
Yuav ua li cas tawg 40G rau hauv 4 * 10G ntawm pebMylinking™ Network Packet Broker ML-NPB-3210+ ?
Siv piv txwv: Lus Cim: Yuav kom qhib tau qhov breakout function ntawm port 40G ntawm Command Line, yuav tsum tau rov pib dua lub cuab yeej
Yuav kom nkag mus rau CLI configuration hom, nkag mus rau hauv lub cuab yeej los ntawm qhov chaw nres nkoj serial lossis SSH Telnet. Khiav "ua kom muaj zog---teeb tsa lub davhlau ya nyob twg---interface ce0---ceev 40000---tawg tawm"cov lus txib ua ntu zus kom qhib tau qhov chaw nres nkoj CE0. Thaum kawg, rov pib dua lub cuab yeej raws li tau hais kom ua. Tom qab rov pib dua, lub cuab yeej siv tau li qub.
Tom qab lub cuab yeej rov pib dua, qhov chaw nres nkoj 40G CE0 tau tawg ua 4 * 10GE chaw nres nkoj CE0.0, CE0.1, CE0.2, thiab CE0.3. Cov chaw nres nkoj no tau teeb tsa sib cais li lwm qhov chaw nres nkoj 10GE.
Piv txwv li qhov kev pab cuam: yog kom qhib qhov kev ua haujlwm ntawm qhov chaw nres nkoj 40G ntawm kab hais kom ua, thiab faib qhov chaw nres nkoj 40G ua plaub qhov chaw nres nkoj 10G, uas tuaj yeem teeb tsa sib cais li lwm qhov chaw nres nkoj 10G.
Cov txiaj ntsig thiab qhov tsis zoo ntawm kev tawg paj
Cov txiaj ntsig ntawm kev tawg:
● Qhov ceev ntau dua. Piv txwv li, lub qhov hloov pauv 36-chaw nres nkoj QDD tuaj yeem muab qhov ceev peb npaug ntawm lub qhov hloov nrog cov chaw nres nkoj downlink ib txoj kab. Yog li ua tiav tib tus lej ntawm kev sib txuas siv tus lej tsawg dua ntawm cov qhov hloov pauv.
● Nkag mus rau cov interfaces qis dua. Piv txwv li, lub QSFP-4X10G-LR-S transceiver ua rau lub switch nrog tsuas yog QSFP ports txuas 4x 10G LR interfaces ib qho chaw nres nkoj.
● Kev Txuag Nyiaj Txiag. Vim tsis tas yuav siv cov khoom siv niaj hnub xws li lub chassis, daim npav, cov khoom siv fais fab, cov kiv cua, ...
Qhov tsis zoo ntawm kev tawg paj:
● Txoj kev hloov pauv nyuaj dua. Thaum ib qho ntawm cov chaw nres nkoj ntawm lub transceiver tawg, AOC lossis DAC, puas lawm, nws yuav tsum tau hloov tag nrho lub transceiver lossis cable.
● Tsis yooj yim hloov kho tau. Hauv cov keyboards uas muaj ib txoj kab downlinks, txhua qhov chaw nres nkoj raug teeb tsa ib tus zuj zus. Piv txwv li, ib qho chaw nres nkoj tuaj yeem yog 10G, 25G, lossis 50G thiab tuaj yeem lees txais txhua hom transceiver, AOC lossis DAC. Ib qho chaw nres nkoj QSFP-xwb hauv hom breakout xav tau txoj hauv kev ua pawg, qhov twg txhua qhov interfaces ntawm transceiver lossis cable yog tib hom.
