NVIDIA Mellanox MSN3420-CS2FC 36-Port QSFP28 EDR InfiniBand Switch

• 36 QSFP28 ports: Provides high-density EDR InfiniBand connectivity in a compact 1U platform, helping HPC and cluster operators connect more endpoints per rack unit. 
• Switch-IB 2 architecture: Provides a purpose-built InfiniBand switching platform for high-performance fabric deployments rather than a generic Ethernet switch. 
• EDR InfiniBand: Supports the EDR generation of InfiniBand connectivity, making the platform suitable for high-throughput, latency-sensitive cluster networking.
• 1U rack form factor: Concentrates 36 QSFP28 ports in a single rack unit, helping maximize network density and preserve rack space. 
• Unmanaged configuration: Reduces operational complexity where a dedicated unmanaged fabric switch is appropriate for the deployment. 
• Dual AC power supplies: Provides two AC PSU positions for a more resilient power architecture than a single-PSU configuration. 
• Standard-depth chassis: Fits conventional data-center rack environments where standard-depth equipment is preferred. 
• P2C airflow: Uses power-to-connector airflow, allowing facilities teams to align the switch with compatible rack cooling layouts. 
• Rail kit: Supports rack installation without requiring a separately specified mounting solution.

Why Choose This Product?

• Exact 36-port QSFP28 density: Gives HPC infrastructure teams a high-density fabric switching option in a compact 1U chassis.
• EDR InfiniBand focus: Designed around an InfiniBand fabric rather than being an Ethernet switch incorrectly positioned for HPC use.
• Switch-IB 2 platform: Provides a dedicated Mellanox InfiniBand switching architecture for compatible high-performance environments.
• Dual AC PSU configuration: Gives data-center teams two AC power inputs for infrastructure resilience planning.
• Unmanaged deployment model: Appropriate where the network architecture calls for a dedicated fabric switch without conventional switch-management requirements.
• Standard-depth installation: Simplifies integration into conventional data-center rack layouts.
• P2C airflow: Helps match the switch to facilities using a power-to-connector cooling direction.
• Clear model differentiation: The CS2FC identifier helps procurement teams distinguish this 36-port EDR InfiniBand model from the similarly named CB2FC Ethernet switch.
