Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN MCX623106AS-CDAT is a dual-port 100GbE network adapter that adds hardware Secure Boot to the ConnectX-6 Dx platform, protecting adapter firmware integrity against unauthorized modification. It connects via a PCIe 4.0 x16 host interface and delivers two 100GbE QSFP56 ports with RoCE v2 RDMA offload for high-throughput, low-latency data movement. Secure Boot validates that only cryptographically signed firmware images can run on the device, reducing the attack surface for firmware-level exploits in security-sensitive deployments such as financial services, government and regulated enterprise environments. The card is form-factor and functionally aligned with HPE's equivalent options (HPE part numbers P53442-001 and P25960-B21), making it a suitable drop-in for OEM-based server refresh and expansion projects. Combined with SR-IOV, overlay network offloads and standard ConnectX-6 Dx management tooling, the MCX623106AS-CDAT balances high-performance networking with firmware-level security assurance.
