I-Cisco Nexus 34180YC ukuya kumaseva e-Supermicro SYS-1029U-TR25M

Mashi 19, 2021

Eminyakeni emihlanu kuya kweyisikhombisa eyedlule isivinini esivame kakhulu sokuxhuma phakathi kwamashishi eqabunga le-Top of Rack (ToR) kumaseva ekhompuyutha nesitoreji esingaphansi kube ngu-10Gbps.Izikhungo eziningi zedatha ye-hyperscale kanye nezikhungo zedatha yebhizinisi ezinkulu nakakhulu zithuthela lezi zixhumanisi zokufinyelela ku-25Gbps.Lokhu kuxhumana kungase kwakhiwe kusetshenziswa izintambo ezingu-25Gbps Direct Attached Copper (DACs), Active Optical Cables (AOCs), noma ngamapheya e-SFP28 25Gbps ama-transceiver optical kanye nentambo efanele ye-duplex fibre optic jumper.

Ukuze ubonise lolu hlelo lokusebenza ngemikhiqizo yomhlaba wangempela, iswishi ye-ToR evela kuchungechunge lwe-Cisco's Nexus 3000 kanye neseva efakwe ku-rack evela kwa-Supermicro kukhethiwe.Okuwukuphela kwezinye izingcezu ezidingekayo ama-Fiberconcepts SFP-25G-SR-s multimode transceivers kanye nezintambo zokuchibiyela ze-OM4 multimode.

UKUSHINTSHWA KWE-TOR LEAF:CiscoI-Nexus 34180YC

Iplathifomu ye-Nexus 3400 iyingxenye yesizukulwane sakamuva se-Nexus®3000 Series Switches egxilile.Uchungechunge lwe-3000 luqondiswe isikwele kuzinhlelo zokusebenza ze-ToR.Wonke amalungu ayimikhiqizo yokucushwa ehlanganisiwe (i-1RU).Kuwo wonke lo mndeni wemikhiqizo empeleni wonke amanani atholakalayo we-optical ethernet ayanikezwa, kusukela ku-1G kuya ku-400G.

I-Nexus 34180YC iyiswishi ekahle yokubonisa ukusetshenziswa komkhiqizo we-INTCERA, i-transceiver ye-Cisco ehambisanayo ye-SFP-25G-SR-S.Lokhu kushintsha kunikeza ukuguquguquka okukhulu kuzivinini zamachweba, okumboza amanani we-1G, 10G, 25G, 40G kanye ne-100G.I-34180YC iyahleleka ivumela umsebenzisi kumakhasimende ukuthi alungise indlela yokudlulisela iphakethe ngendlela ehambisana nezidingo zezicelo zabo.Isibonelo, izinhlelo zokusebenza zokuhweba ngezimali ezinesivinini esikhulu zingalungiselelwa ukubambezeleka okuphansi okungenzeka.Le swishi ifakwe amachweba angu-48 SFP+/SFP28 (1G/10G/25G) kanye namachweba angu-6 QSFP+/QSFP28 (40G/100G).Iswishi isekela isilinganiso somugqa ogcwele Ushintsho lwe-Layer 2/3 kuwo wonke lawa machweba, afinyelela ku-3.6 Terabits/isekhondi kanye no-1.4 Gigapackets/isekhondi.

I-34180YC ingase ifakwe ngohlu olubanzi lwezinhlobo ze-transceiver optical interface kuwo wonke amanani amaningi ashiwo ngenhla.Amathebula angezansi afaka izinhlobo zokudlulisa ulwazi ezihambisanayo zezigaba ezimbili zamachweba ekushintsheni.
