Product Description
The NVIDIA Mellanox ConnectX-6 MCX623436AC-CDAB is a 2-port 100GbE OCP3.0 adapter built on the ConnectX-6 Dx EN controller (MT28928A0-XCCF-CE), pairing dual 100Gb/s QSFP56 ports with hardware Secure Boot and Crypto offload. Connected via PCIe 4.0 x16 and supporting RoCE v2 RDMA, it delivers up to 200Gb/s aggregate throughput while authenticating firmware at every boot and offloading IPsec/TLS encryption to dedicated on-card engines. This combination of high dual-port bandwidth, verified firmware integrity, and hardware-accelerated encryption makes the MCX623436AC-CDAB well suited for security-conscious hyperscale and enterprise deployments — such as encrypted east-west data-center traffic, multi-tenant cloud fabrics, and regulated industries — that need both maximum throughput and a hardened security posture from a single OCP 3.0 network adapter.
