Yog lawm. PCIe yog pem hauv ntej- siv tau nrog cov qhov loj dua. Daim npav x4 ua haujlwm hauv x8 lossis x16 qhov - nws tsuas yog siv txoj kab uas nws xav tau. Qhov rov qab tsis ua haujlwm: daim npav x8 tsis tuaj yeem haum rau hauv x4 qhov.
Puas yuav muaj SFP + module ua haujlwm hauv 10G fiber ntau NIC?
Tsis yog. Ntau tus neeg muag khoom NIC khaws cov npe transceiver uas raug lees paub thiab tuaj yeem thaiv cov modules uas tsis paub txog ntawm qib tsav tsheb. Intel thiab Mellanox / NVIDIA paub txog qhov no. Nco ntsoov xyuas NIC tus neeg muag khoom cov ntaub ntawv sib raug zoo ua ntej yuav khoom thib peb -tog optics.
Kuv puas xav tau ib qho -hom lossis multimode fiber ntau rau 10G kev sib txuas?
Ob leeg tuaj yeem txhawb nqa 10G. Qhov kev txiav txim siab yog qhov kev ncua deb thiab cov infrastructure uas twb muaj lawm. Multimode (OM3 / OM4) yog tus qauv rau kev khiav mus txog 300-400 meters hauv ib lub tsev. Tib - hom (OS2) yuav tsum muaj rau lub tsev kawm ntawv ntev dua lossis kev sib koom ua ke - tsev txuas. Xaiv raws li qhov twb tau teeb tsa - pebOM3 vs OM4 phau ntawv qhianpog qhov luv - ncav cuag qhov sib txawv.
Puas yog dual -chaw nres nkoj ib txwm zoo dua li ib qho -chaw nres nkoj?
Dual-chaw nres nkoj muab qhov yooj yim dua, tab sis ib qho -chaw nres nkoj feem ntau yog qhov kev xaiv zoo rau cov chaw ua haujlwm lossis tsis yog- cov kev txuas tseem ceeb uas tus nqi thiab qhov yooj yim tseem ceeb tshaj qhov rov ua dua. Yuav dual -chaw nres nkoj thaum koj xav tau kev ua tsis tiav, txuas kev sib sau ua ke, lossis kev sib faib network.
Kuv puas tuaj yeem siv DAC cable tsis yog fiber ntau transceiver thiab thaj qaum?
Rau luv luv (feem ntau 1-5 meters nyob rau hauv tib lub khib los yog nyob ib sab racks), ib tug DAC cable hloov ob lub transceiver thiab lub fiber thaj qaum ntawm tus nqi qis thiab qis zog noj. Xyuas tias koj NIC thiab hloov ob qho tib si txhawb nqa DAC cables ntawm koj lub hom phiaj ceev.
Dab tsi connector hom fiber ntau NICs siv?
Feem ntau SFP + thiab SFP28 transceivers siv LC duplex connectors. Qee qhov qub 1G SFP modules yuav siv SC connectors. Ua ntej khiav cable, paub meej tias qhovconnector homxav tau los ntawm koj tus transceiver tshwj xeeb.
