NVIDIA ConnectX Compatibility

The NVIDIA ConnectX-8 C8240 (MPN 900-9X81Q-00CN-ST0) is a high-performance PCIe network adapter designed for AI infrastructure, high-performance computing (HPC), hyperscale data centers, cloud networking, and other high-bandwidth applications.

This adapter uses a PCIe 6.0 x16 host interface and a Half-Height Half-Length (HHHL) form factor. The card features two QSFP112 ports for high-speed network connectivity and supports both Ethernet, up to 400GbE, and 400Gb/s NDR InfiniBand networking.

Before purchasing, verify that your server has an available PCIe x16 slot with the required PCIe generation and platform support, sufficient physical clearance for an HHHL adapter, and appropriate operating system and NVIDIA driver support.

Network connectivity also requires compatible QSFP112 cables, transceivers, or optical modules appropriate for the intended Ethernet or InfiniBand deployment.

For multi-host or SocketDirect deployments, verify that the server platform supports the appropriate PCIe 6.0 x16 SocketDirect/Multi-Host configuration.

This adapter is intended for data-center and high-performance networking environments. Verify server, firmware, driver, cable, transceiver, switch, and operating-system compatibility before ordering.
