FAQ
Ask a QuestionFind answers to common questions about our products.
Can I use this card for Ethernet now and move to InfiniBand later?
Yes. This is a VPI adapter, so the port can be configured for either Ethernet or InfiniBand. It is a practical choice for deployments that may move from 200GbE to HDR InfiniBand in the future.
Does the card automatically switch between Ethernet and InfiniBand?
No. The port type should be configured through NVIDIA/Mellanox tools such as mlxconfig, and a restart may be required for the change to take effect. Please confirm the target mode before connecting it to your switch fabric.
Can the QSFP56 port work with QSFP28 transceivers or cables?
QSFP28 modules or cables may be used on the QSFP56 port when the speed, firmware, and link mode are supported. For full 200G operation, use compatible QSFP56 HDR / 200GbE optics, DAC, or AOC.
What is the difference between ConnectX-6 VPI and ConnectX-6 Dx?
ConnectX-6 VPI is designed for flexible InfiniBand and Ethernet deployment. ConnectX-6 Dx focuses on Ethernet environments and includes different offload and security-oriented capabilities, so the right choice depends on the network architecture.
Is an HCA the same as an InfiniBand adapter?
Yes. In InfiniBand environments, the adapter card is commonly called an HCA, or Host Channel Adapter. This ConnectX-6 VPI card can operate as an HCA when configured for InfiniBand.
