NVIDIA ConnectX Compatibility

The Mellanox ConnectX-6 MCX683105AN-HDAT is a ConnectX-6 DE single-port InfiniBand adapter designed for high-performance server and data-center environments, including high-performance computing (HPC), AI infrastructure, cloud networking, distributed storage, and other bandwidth-intensive applications.

The adapter uses a PCIe 4.0 x16 host interface with backward compatibility with earlier PCIe generations. NVIDIA specifies PCIe Gen 3.0/4.0 x16 operation and backward compatibility with PCIe 3.0, 2.0, and 1.1. The card uses a Half-Height Half-Length (HHHL) form factor measuring approximately 2.71 × 6.6 inches (68.90 × 167.65 mm) and uses a tall bracket.

The MCX683105AN-HDAT features a single QSFP56 InfiniBand port and supports InfiniBand data rates including HDR, HDR100, EDR, FDR, QDR, DDR, and SDR, with HDR providing up to 200 Gb/s. This adapter is an InfiniBand-only ConnectX-6 DE model and does not provide Ethernet functionality.

The adapter requires an appropriate PCIe slot capable of providing the required power and airflow, as well as sufficient physical clearance for the HHHL card and tall bracket. Verify the host server's PCIe, power, cooling, airflow, and mechanical requirements before installation.

The MCX683105AN-HDAT is specified with no cryptographic functionality. NVIDIA identifies this exact OPN as a ConnectX-6 DE InfiniBand adapter with No Crypto.

For InfiniBand connectivity, use compatible QSFP56 InfiniBand cables and optical or copper connectivity appropriate for the intended InfiniBand speed and deployment. Verify cable, switch, and physical-media compatibility before installation.

Operating-system compatibility depends on the applicable NVIDIA/Mellanox driver and firmware versions. NVIDIA's firmware documentation lists MLNX_OFED, MLNX_EN, and WinOF-2 software for this OPN; specific supported operating systems should be verified against the applicable driver release notes.

Before purchasing, verify that the host system provides a compatible PCIe slot, sufficient power and airflow, adequate physical clearance for the HHHL/tall-bracket card, compatible driver and firmware support, and compatible InfiniBand networking infrastructure.

Frequently Asked Questions

What is the Mellanox ConnectX-6 MCX683105AN-HDAT?

The Mellanox ConnectX-6 MCX683105AN-HDAT is a high-performance single-port DE network adapter designed for server and data-center networking, high-performance computing (HPC), AI infrastructure, cloud networking, distributed storage, and other high-bandwidth applications. It features a single QSFP56 port and a PCIe 4.0 x16 host interface.

What speed does the MCX683105AN-HDAT support?

The MCX683105AN-HDAT supports HDR InfiniBand networking at speeds up to 200Gb/s. Actual link speed depends on the connected InfiniBand switch, cable, network configuration, and supported infrastructure.

Can the MCX683105AN-HDAT be used for InfiniBand?

Yes. The MCX683105AN-HDAT is designed for InfiniBand networking and supports HDR InfiniBand at up to 200Gb/s. it also supports SDR, DDR, QDR, FDR, EDR and HDR100.

Is the MCX683105AN-HDAT a VPI adapter?

No. The MCX683105AN-HDAT is a Mellanox ConnectX-6 DE network adapter. NVIDIA specifically distinguishes the DE from the VPI cards. The DE is InfiniBand-only; it does not have Ethernet functionality. NVIDIA's own developer forum explicitly describes the DE's absence of VPI and consequently Ethernet functionality.

What PCIe interface does the MCX683105AN-HDAT use?

The MCX683105AN-HDAT uses a PCIe 4.0 x16 host interface. The host system must provide an appropriate PCIe x16 slot and sufficient system resources for the adapter.

What connector does the MCX683105AN-HDAT use?

The MCX683105AN-HDAT uses a single QSFP56 networking port. The port is intended for high-speed InfiniBand networking and requires compatible QSFP56 cables, transceivers, or optical infrastructure.

What is the form factor of the MCX683105AN-HDAT?

The MCX683105AN-HDAT is a PCIe 4.0 x16 network adapter with a single QSFP56 port. This model uses a tall bracket and requires appropriate full-height expansion-slot clearance in the host chassis.

Does the MCX683105AN-HDAT support cryptographic functionality?

No. The MCX683105AN-HDAT is specified with no cryptographic support. Customers requiring hardware cryptographic functionality should select a ConnectX-6 variant specifically configured with the required cryptographic capabilities.

What is the MPN of the Mellanox ConnectX-6 MCX683105AN-HDAT?

The legacy manufacturer part number (MPN) is MCX683105AN-HDAT. 900-9X0BC-001H-ST1 is NVIDIA's name for the network card.

Does the MCX683105AN-HDAT support Windows?

ConnectX-6 adapters are supported by NVIDIA/Mellanox drivers for supported Windows operating systems. Verify the specific Windows version, driver release, firmware requirements, and supported networking features before deployment.

Does the MCX683105AN-HDAT support InfiniBand on Windows?

InfiniBand support on Windows depends on the supported ConnectX-6 driver, Windows version, firmware, and deployment configuration. Verify the applicable NVIDIA/Mellanox driver documentation before deploying the adapter for InfiniBand under Windows.

What type of server is compatible with the MCX683105AN-HDAT?

The MCX683105AN-HDAT is intended for server and data-center environments that provide an appropriate PCIe x16 slot, sufficient power delivery, cooling, airflow, physical clearance, and compatible NVIDIA/Mellanox driver support.

Can I install the MCX683105AN-HDAT in a desktop PC or workstation?

Compatibility with desktop or workstation systems should not be assumed. The adapter is designed primarily for server and data-center environments and requires appropriate PCIe connectivity, power, cooling, airflow, physical clearance, firmware, and driver support.

What cables or transceivers work with the MCX683105AN-HDAT?
