NVIDIA Mellanox ConnectX-6 Dx MCX623109AC-CDAT

The NVIDIA Mellanox ConnectX-6 Dx MCX623109AC-CDAT is a dual-port 100GbE network adapter built on the ConnectX-6 Dx controller with a PCIe 4.0 x16 host interface, distinguished by its DSFP (Dual Small Form-factor Pluggable) connectors rather than the more common QSFP56 cage. This SKU combines Secure Boot firmware attestation with an onboard cryptography engine for inline IPsec/TLS offload, targeting security-conscious deployments that also require DSFP-based cabling compatibility, such as certain switch and cable-management ecosystems. RoCE v2 RDMA provides low-latency, high-throughput data movement, while ASAP² hardware offload accelerates Open vSwitch processing and SR-IOV virtualization to minimize host CPU overhead. With dual 100GbE ports, the card supports both bandwidth aggregation and link redundancy. The MCX623109AC-CDAT is well suited to data center racks standardized on DSFP optics and cabling that also require hardware-rooted firmware security and encrypted networking.
