The NVIDIA ConnectX-7 MCX755106AS-HEAT is a high-performance VPI network adapter designed for data-center networking, AI infrastructure, high-performance computing, cloud data centers, distributed storage, and other high-bandwidth applications. It features two QSFP112 ports and a PCIe 5.0 x16 host interface.

The MCX755106AS-HEAT supports Ethernet speeds up to 200GbE and NDR200 200Gb/s InfiniBand. NVIDIA also specifies support for additional Ethernet and InfiniBand rates depending on the network configuration and connected infrastructure.

Yes. NVIDIA specifies 200GbE as the default Ethernet mode for the MCX755106AS-HEAT. The adapter also supports lower Ethernet rates including 100GbE, 50GbE, 25GbE, and 10GbE, depending on the network configuration.

Yes. The MCX755106AS-HEAT is a VPI adapter supporting both Ethernet and InfiniBand. NVIDIA specifies NDR200 as the InfiniBand mode and also documents support for HDR, HDR100, EDR, FDR, and SDR.

The default networking mode is 200GbE Ethernet. NVIDIA identifies the MCX755106AS-HEAT as supporting NDR200 InfiniBand and 200GbE Ethernet, with Ethernet 200GbE as the default protocol and data rate.

Yes. NVIDIA WinOF-2 provides Windows drivers for supported ConnectX adapters and supports both Ethernet and InfiniBand networking. The exact supported Windows versions and driver features depend on the WinOF-2 release and operating-system configuration.

Yes. NVIDIA provides WinOF-2 drivers for supported ConnectX-7 adapters and Windows operating systems. Verify the specific Windows version, driver release, and required networking protocol before deployment.

The MCX755106AS-HEAT uses a PCIe 5.0 x16 host interface. NVIDIA also documents compatibility with PCIe 4.0 and PCIe 3.0 systems.

The MCX755106AS-HEAT uses two QSFP112 networking ports. The ports support Ethernet and InfiniBand operation.

Yes. The MCX755106AS-HEAT supports both Ethernet and InfiniBand networking. NVIDIA specifies 200GbE Ethernet as the default mode and NDR200 200Gb/s InfiniBand.

The MCX755106AS-HEAT uses a Half-Height Half-Length (HHHL) PCIe form factor measuring approximately 2.71 × 6.6 inches (68.90 × 167.65 mm). NVIDIA specifies a tall bracket for this adapter.

Yes. NVIDIA specifies Secure Boot as enabled for the MCX755106AS-HEAT.

No. NVIDIA specifies Crypto Disabled for the MCX755106AS-HEAT.

The manufacturer part number (MPN) is MCX755106AS-HEAT. The corresponding NVIDIA SKU is 900-9X7AH-0078-DTZ.

The MCX755106AS-HEAT is intended for server and data-center environments that provide an appropriate PCIe slot, power delivery, airflow, physical clearance, and operating-system and driver support. Verify the server manufacturer's PCIe, power, cooling, and physical compatibility requirements before installation.

Compatibility with desktop or workstation systems should not be assumed. The adapter is designed for server and data-center environments and requires appropriate PCIe connectivity, power, airflow, physical clearance, and driver support. Verify the system requirements before installation.

The adapter uses dual QSFP112 ports and requires compatible QSFP112 cables, optical modules, or active/passive cable solutions appropriate for the intended Ethernet or InfiniBand deployment. The exact cable or optical configuration depends on the network speed, switch, distance, and networking protocol.

Yes. NVIDIA specifies 200GbE Ethernet and NDR200 200Gb/s InfiniBand for the MCX755106AS-HEAT. The actual link speed depends on the connected switch, cable or transceiver, network configuration, and supported protocol.
