FAQ
Ask a QuestionFind answers to common questions about our products.
Can I use both QSFP56 ports for two independent 100GbE links?
Yes. This adapter provides dual QSFP56 Ethernet ports and supports up to 100GbE per port, so it can be used for two separate 100G uplinks when the server slot, switch ports, and cabling are properly matched.
Will this card work with existing 25G, 40G, or 50G Ethernet environments?
Yes, the adapter supports 1/10/25/40/50/100GbE speeds.
Can the QSFP56 port be split into 4×25G using a breakout cable?
No.NVIDIA forum guidance states that ConnectX NIC ports do not support physical lane splitting, so breakout planning should be handled on the switch side rather than expecting one NIC port to appear as four independent ports.
Is this card suitable for RoCE-based storage or AI cluster traffic?
Yes. ConnectX-6 Dx supports RoCE for low-latency Ethernet RDMA, making it suitable for high-performance storage, virtualization, and data center workloads when the Ethernet fabric is correctly configured.
