Frequently Asked Questions
What is the difference between ConnectX-5 and ConnectX-6?
While both are high-performance network cards, ConnectX-6 offers higher throughput (200Gb/s) and enhanced security features compared to ConnectX-5's 100Gb/s capability. However, the ConnectX-5 remains an excellent choice for most enterprise and HPC applications with its proven reliability and comprehensive feature set.
Does this NIC card support both InfiniBand and Ethernet?
Yes, the ConnectX-5 adapter card supports both InfiniBand and Ethernet protocols, offering flexibility for different network environments. The same physical hardware can be configured for either protocol through firmware settings.
What operating systems are supported?
The ConnectX-5 network card supports a wide range of operating systems including RHEL/CentOS, Windows Server, FreeBSD, VMware ESXi, and various Linux distributions through the OpenFabrics Enterprise Distribution (OFED).
Compatibility Notes
- Ensure your system has an appropriate PCIe x16 slot (Gen3 or Gen4) for optimal performance
- For Ethernet operation at speeds below 100GbE, appropriate adapters may be required
- When using NVIDIA Socket Direct technology in virtualization scenarios, certain restrictions may apply
- Verify compatible cable types (passive copper, active optical) for your specific deployment
- Check firmware and driver requirements for specific offload capabilities
