Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN MCX623435AS-VDAI is a single-port 200GbE OCP Spec 3.0 adapter built on the ConnectX-6 Dx ASIC (MT28928A0-XCCF-CE), combining line-rate Ethernet performance with hardware Secure Boot protection. Delivered over a PCIe 4.0 x16 host interface through one QSFP56 port, it targets deployments that require firmware integrity assurance without the added cost of inline Crypto (IPsec/TLS) offload present on the AC-VDAB variant. Secure Boot authenticates the adapter's firmware image at every power cycle, guarding against tampering and unauthorized firmware modification in supply-chain-sensitive environments. RDMA over Converged Ethernet (RoCE v2) provides low-latency, CPU-efficient data movement for storage and distributed-compute traffic. Housed in the OCP 3.0 form factor with an internal lock bracket, the MCX623435AS-VDAI is well suited for enterprise and government data centers that mandate verified-boot network hardware while keeping cost and power closer to the base ConnectX-6 Dx EN configuration.
