4. Setha

4.1. Ukufakwa ngokomzimba

Iswishi ye-MSN3700C yenzelwe ukufakwa kwesitimela, ifanelekela ama-rack eseva ajwayelekile.

1. Namathisela ikhithi yesitimela enikeziwe ku-rack yeseva ngokwemiyalelo yekhithi yesitimela.
2. Slayida ngokucophelela iswishi kuma-rails afakiwe kuze kube yilapho ingena endaweni yayo.
3. Vikela iswishi ku-rack usebenzisa izikulufo ezifanele.

4.2. Ukuxhunywa kwamandla

Xhuma izinsiza ezimbili zikagesi ze-AC kuswishi bese uxhuma emthonjeni wamandla osekelwe phansi.

• Faka iyunithi ngayinye yokunikeza ugesi endaweni yayo ekhethiwe kuswishi.
• Xhuma izintambo zikagesi ezivela kumayunithi okuhambisa ugesi ezindaweni zokuxhuma ze-AC ezihlukene, ezisekelwe phansi ukuze zingaphinde zisebenze.
• Qinisekisa ukuthi ama-LED esibonakaliso samandla kuswishi ayakhanya.

4.3. Ukuxhumana Kwenethiwekhi

Iswishi inamachweba angu-32 e-SFP+ okuxhuma kwe-100 Gigabit Ethernet.

• Faka ama-transceiver e-SFP+ ahambisanayo emachwebeni afunwayo.
• Xhuma izintambo ze-optical fiber ezivela kuma-transceivers kumadivayisi akho enethiwekhi (amaseva, ezinye izinkinobho).
• Amachweba angahlukaniswa ukuze asekele amachweba afinyelela ku-128x 10/25GbE kusetshenziswa izintambo zokuhlukanisa ezifanele kanye nama-transceivers.

5. Iziqondiso Zokusebenza

5.1. Ukusebenza Okuyisisekelo

I-MSN3700C isekela amakhono aphelele okushintsha i-Layer-2 kanye ne-Layer-3.

• Ukushintsha kwe-Layer-2: Kwenza kube lula ukudluliselwa kwedatha okuphumelelayo ngaphakathi kwesigaba senethiwekhi yendawo.
• Ukushintsha kwe-Layer-3: Inika amandla ukuqondisa phakathi kwezingxenye zenethiwekhi ezahlukene kanye nama-subnet.

5.2. Izici Ezithuthukile

Iswishi ifaka izici ezithuthukisiwe zokuxhumana kwesikhungo sedatha sesimanje:

• Ezokuthutha ze-RoCE: Ukusekelwa okuqinile kwe-RDMA phezu kwe-Converged Ethernet, okunika amandla i-NVMe phezu kwezinhlelo zokusebenza ze-Fabric kanye ne-Machine Learning kusetshenziswa i-NVIDIA GPUDirect.
• I-VXLAN: Isikali se-VXLAN esingcono kakhulu se-virtualization yenethiwekhi, sisekela umzila we-VXLAN odlula nge-single-pass osebenza kahle kakhulu.
• I-Telemetry Yenethiwekhi: Izici ezifana ne-NVIDIA What Just Happened (WJH) telemetry, ama-histogram asheshiswe yihadiwe, kanye nehadiwe elungele i-Inband Network Telemetry (INT) zinikeza ukubonakala okujulile ekusebenzeni kwenethiwekhi futhi zinciphisa kakhulu isikhathi esimaphakathi sokuxazulula inkinga.
• Ipayipi Elingahlelwa: Ivumela ukuhlaziya, ukucubungula, kanye nokuhlela amaphakethe ngokuhlelekile ukuze kusebenze inethiwekhi eguquguqukayo.

6. Isondlo

6.1. Izimo Zemvelo
