Product Description
The NVIDIA Mellanox ConnectX-6 Dx MCX623432AC-GDAB is a dual-port 50GbE OCP 3.0 Small Form Factor network adapter that brings the full ConnectX-6 Dx feature set — Secure Boot and inline crypto offload included — to Open Compute Project-compliant hyperscale and enterprise platforms. Built on the ConnectX-6 Dx ASIC (MT28928A0-XCCF-CE) and connected via PCIe 4.0 x16, the card delivers two 50Gb/s SFP56 ports with hardware-accelerated RDMA over Converged Ethernet (RoCE v2). Secure Boot authenticates firmware at power-on, while the onboard crypto engine offloads IPsec/TLS encryption in hardware, meeting the security and compliance requirements of regulated cloud and telco deployments. ASAP² virtual switching offload, SR-IOV, and overlay network acceleration reduce host CPU overhead in virtualized and NFV environments. The OCP 3.0 form factor enables tool-less, hot-swappable installation in modern hyperscale chassis, making the MCX623432AC-GDAB well suited to security-hardened, high-throughput cloud infrastructure at scale.
