NVIDIA MCX755106AC-HEAT 200Gbps dual-port network card

SKU CH-2E1W-FTEAW MPN MCX755106AC-HEAT

Dual-port 200Gbps Ethernet adapter with PCIe 5.0 x16 and QSFP112 cages for high-bandwidth server connectivity

  • Speed200Gbps
  • InterfaceOpen Computer Project (OCP) 3.0

Part MCX755106AC-HEAT

Data Rate 200GbE/NDR200

Network Interface QSFP112 / Dual Ports

  • Dual-port 200Gbps throughput for high-bandwidth server connectivity
  • PCI Express 5.0 x16 interface enables fast data transfer rates
  • OCP 3.0 bracket height fits standard open compute platforms
  • QSFP112 optical fiber ports support efficient long-distance networking

NVIDIA ConnectX-7 200Gbps Dual-Port Adapter

This NVIDIA ConnectX-7 adapter card delivers 200Gbps connectivity through two QSFP112 ports. It installs in a PCI Express 5.0 x16 slot and uses an OCP 3.0 bracket. The card suits data-centre servers and high-performance workstations that require low-latency, high-throughput networking.

Suited for OCP 3.0 slots with PCIe 5.0 x16

This card fits systems that provide an OCP 3.0 form-factor slot wired for PCI Express 5.0 x16. Builders using standard PCIe brackets, older PCIe generations, or single-port requirements should look at other models.

Dual-port 200Gbps over optical QSFP112

The decisive specification is the dual-port 200Gbps Ethernet rate over optical QSFP112 transceivers. That bandwidth and port count determine whether the adapter matches the cluster interconnect or storage fabric you are deploying.

Questions about this item

Does my server need an OCP 3.0 slot to install the MCX755106AC-HEAT?

Yes, the adapter uses the Open Computer Project 3.0 bracket height, so the host must provide a compatible OCP 3.0 slot.

Will the dual-port 200Gbps card operate in a PCI Express 5.0 x16 slot alongside older PCIe 4.0 devices?

The card requires a PCI Express 5.0 x16 connection for full 200Gbps throughput; it will negotiate down to the slot speed if an older generation is used.

How can I verify the QSFP112 ports are linking at 200Gbps after installation?

Check the link status LEDs or the driver-reported speed; each port should show a 200Gbps active connection when proper optics and cables are fitted.
