ConnectX-6 DX EN 100Gbps Dual Port

This Mellanox network adapter delivers 100Gbps Ethernet connectivity across two ports for servers and high-performance workstations. It uses a PCI Express 4.0 x16 interface to provide the bandwidth needed for demanding data-centre and compute workloads. The card is built for environments where low latency and high throughput are essential.

Dual-port 100GbE changes cabling and switch planning

Two 100Gbps ports let you aggregate bandwidth or create redundant links without adding a second card. This reduces the number of occupied PCIe slots and simplifies cable management in dense rack configurations. The adapter supports standard Ethernet framing so it integrates with existing 100GbE switch infrastructure.

Verify PCIe 4.0 x16 slot and 100GbE optics

Your motherboard must provide a full-length PCI Express 4.0 x16 slot for the card to operate at its rated speed. You also need compatible 100GbE transceivers or direct-attach cables that match the port type on the adapter. Confirm that your switch ports and cabling support 100Gbps Ethernet before ordering.

Questions about this item

What maintenance will the MCX623106AC-CDAT need over its service life?

The card has no moving parts and no user-serviceable components, so no scheduled maintenance is required.

Which limit appears first when both 100Gbps ports run continuously?

The PCI Express 4.0 x16 host interface sets the sustained throughput ceiling for dual-port traffic.

How much heat and noise does the adapter produce under all-day load?

Passive cooling handles the thermal load silently; the card adds no audible noise to the server chassis.
