NVIDIA 920-9N302-00F7-0C2 | Spectrum-3 64-Port 100GbE Switch, 6.4Tb/s, 2U

Q: What network speeds are supported on the QSFP28 ports?
A: All 64 QSFP28 ports support flexible speeds including 1GbE, 10GbE, 25GbE, 40GbE, 50GbE, and 100GbE using appropriate transceivers or breakout cables, allowing mixed-speed deployments within a single switch.

Q: What is Cumulus Linux and can it be replaced?
A: Cumulus Linux is an open-source Debian-based network operating system that provides automation, programmability, and Linux-native network management using tools like Ansible, Python, and standard Linux commands. The switch supports open networking standards and can run alternative network operating systems compatible with the hardware platform.

Q: What deployment scenarios is the MSN4600-CS2FC best suited for?
A: This switch is ideal for spine and super-spine deployments in large data centers, high-density leaf applications, AI/ML training clusters requiring low-latency RDMA over Converged Ethernet (RoCE), cloud service provider networks, and software-defined networking environments requiring open standards and programmability.

Q: What does P2C airflow mean and why does it matter?
A: P2C (Port-to-Connector or Power-to-Connector) airflow means air flows from the power supply side toward the port side of the switch. This is also known as front-to-back airflow. Matching airflow direction across all devices in a rack ensures proper cooling efficiency and prevents hot air recirculation. P2C airflow is commonly used in hot-aisle/cold-aisle data center designs.

Q: Can this switch be used for RDMA and AI/ML workloads?
A: Yes, the Spectrum-3 ASIC provides native support for RoCEv2 (RDMA over Converged Ethernet version 2) with advanced congestion control, priority flow control, and consistent low-latency switching ideal for GPU-to-GPU communication in AI training clusters, high-performance computing, and distributed storage applications.
