Dual-Port 100GbE | QSFP56 | PCIe 4.0 x16 | No Crypto | Tall Bracket

Product Overview

The NVIDIA ConnectX®-6 Dx EN (MPN: MCX623106AN-CDAT) is an enterprise-grade Smart Network Interface Card (SmartNIC) engineered to accelerate mission-critical cloud, virtualization, storage, and artificial intelligence workloads. Delivering up to 200Gb/s aggregate bandwidth across dual 100GbE QSFP56 ports, this adapter leverages PCIe 4.0 x16 connectivity to unlock maximum server throughput with minimal CPU overhead.

This specific model (MCX623106AN-CDAT) is a non-cryptographic variant configured with a standard tall bracket. It is optimized for environments where hardware IPsec/TLS encryption is not required, making it a streamlined, power-efficient choice for hyperscale data centers, NVMe-oF storage arrays, and high-density compute nodes.

Key Features

Dual 100GbE QSFP56 Ports: Provides flexible network topologies with up to 100Gb/s per port using 50G-PAM4 or 25G-NRZ SerDes technology.
PCIe Gen 4.0 x16 Host Interface: Full backward compatibility with PCIe Gen 3.0 slots, offering 16 lanes of 16.0 GT/s bus speed to eliminate host bottlenecks.
Zero-Touch RoCE (RDMA over Converged Ethernet): Enables ultra-low latency (sub-0.8µs) and high-throughput data transfers without requiring complex PFC (Priority Flow Control) or ECN network tuning.
ASAP² Accelerated Switching & Packet Processing: Hardware offload for SDN software-defined networking, SR-IOV, VirtIO, and overlay tunnels (VXLAN, GENEVE, NVGRE) to free up CPU cores.
Advanced Storage Offloads: Direct hardware acceleration for NVMe over Fabrics (NVMe-oF), iSER, NFSoRDMA, SMB Direct, and T10-DIF signature checks.
Streamlined Non-Crypto Profile: Designed without inline cryptographic engines for reduced thermal output and simplified compliance in non-regulated environments.
