Unlock Next-Generation Data Center Agility
The MCX623436AN-CDAB SmartNIC is engineered to address the core challenges of modern cloud and enterprise infrastructure. This advanced network card delivers more than just high-speed 25GbE connectivity; it integrates specialized hardware accelerators to offload complex networking, storage, and security protocols directly from the server CPU. This results in dramatically improved application performance, enhanced data security, and a significantly lower total cost of ownership (TCO), making it a strategic asset for deployments integrated with high-performance switches like the mq9700 series.
1. Product Overview
The NVIDIA ConnectX-6 Lx MCX623436AN-CDAB is a feature-rich, dual-port SmartNIC designed to provide intelligent network acceleration in a standard PCIe low-profile form factor. Equipped with two SFP28 ports supporting both 10GbE and 25GbE speeds, this NIC card acts as a co-processor, handling demanding tasks such as RDMA over Converged Ethernet (RoCE), software-defined networking (SDN) encapsulation, and inline IPsec cryptography. By offloading these workloads, it frees up valuable host processor cycles, enabling servers to support more virtual machines, deliver faster storage access, and run secure communications at line rate without compromise.
2. Key Characteristics
3. Core Technology & Standards
This SmartNIC is built upon a foundation of industry-leading technologies that solve specific data center pain points:
- ASAP² (Accelerated Switch and Packet Processing): This technology enables the network card to perform the data plane functions of a virtual switch, offloading overlay network protocols (VXLAN, GENEVE, NVGRE) from the hypervisor. This dramatically improves virtual machine-to-VM communication performance and reduces host CPU utilization.
- Zero-Touch RoCE (ZTR): A revolutionary approach to RDMA that eliminates the need for complex, network-wide Priority Flow Control (PFC) configuration. ZTR allows RoCE to run efficiently on existing Ethernet networks, simplifying the deployment of low-latency storage and clustering solutions.
- Inline IPsec & Hardware Root of Trust: Provides line-rate encryption for secure network tunnels without performance degradation. Coupled with a hardware-based security root using unique cryptographic keys, it ensures firmware integrity and protects against supply chain attacks.
4. How It Works: The Intelligent Data Path
The MCX623436AN-CDAB functions as an autonomous network processing unit. When data packets arrive, they are immediately classified by the adapter's programmable parser. Traffic destined for RDMA applications is placed directly into application memory, bypassing the kernel and CPU entirely. Overlay network packets are decapsulated by the ASAP2 engine. Secured IPsec traffic is decrypted on the fly. All these operations are executed in parallel at full wire speed within the SmartNIC's silicon. This process effectively transforms the adapter from a passive data pipe into an active processing node, drastically reducing server overhead—a efficiency multiplier that is essential when connecting to high-throughput core networks utilizing mq9700 switches.
5. Target Applications & Deployment Scenarios
- Virtualized Data Centers & Private Clouds: Offloads virtual switch processing to improve VM density and network performance for platforms like VMware, OpenStack, and Kubernetes.
- High-Performance Storage (NVMe-oF): Provides the ultra-low latency RoCE connectivity required for modern, disaggregated storage architectures.
- Telecommunications & Network Function Virtualization (NFV): Accelerates virtual network functions (VNFs) such as firewalls, routers, and 5G core network elements, improving throughput and reducing latency.
- AI/ML and High-Performance Computing (HPC): Facilitates fast data exchange between servers in compute clusters, crucial for distributed training and simulation workloads.
- Secure Enterprise Interconnects: Establishes high-speed, encrypted links between data centers or branch offices for secure data replication and backbone connectivity.
6. Technical Specifications
7. Competitive Advantages
- Optimized Total Cost of Ownership (TCO): By offloading CPU-intensive tasks, it allows servers to support more application workloads or enables the use of lower-core-count, more energy-efficient servers, directly reducing capital and operational expenses.
- Simplified Operations with Zero-Touch RoCE: Removes the operational complexity traditionally associated with deploying high-performance, low-latency RDMA networks, accelerating time-to-value for storage and AI projects.
- Uncompromised Security Performance: Delivers full line-rate encryption, allowing organizations to implement stringent security policies across the entire data path without incurring a performance penalty—a critical capability when interfacing with secured core infrastructure like mq9700-based networks.
- Future-Proof Investment: PCIe 4.0 readiness and support for emerging protocols ensure this NIC card remains a valuable asset through multiple server refresh cycles, protecting your infrastructure investment.

9. Frequently Asked Questions
Q: What is the difference between this model (MCX623436AN-CDAB) and other ConnectX-6 Lx models?
A: The key differentiator often lies in the specific feature set or form factor. The MCX623436AN-CDAB is a PCIe low-profile card with dual SFP28 ports and includes the full suite of accelerators (ASAP2, RoCE, IPsec). Other models may be OCP form factor, have different port counts, or may have certain accelerators disabled. Always verify the specific model number against your requirements.
Q: Can this SmartNIC improve the performance of my existing virtualized environment?
A: Yes, significantly. By offloading the virtual switch data plane via ASAP2, it reduces CPU load on the hypervisor host. This can lead to higher VM density, reduced network latency between VMs, and more CPU resources available for the applications themselves, improving overall performance of your existing network card infrastructure.
Q: Does it require special switches to work with RoCE or ASAP2?
A: For Zero-Touch RoCE, it is designed to work with standard Ethernet switches without requiring special features like PFC, simplifying deployment. For ASAP2 offload, the feature operates between the VMs/hosts and the SmartNIC; the physical network switches (including high-performance models like the mq9700) simply carry the encapsulated tunneled traffic as standard Ethernet frames.
10. Important Installation & Operational Notes
- Thermal Management: Ensure your server chassis provides adequate airflow across the PCIe card area. Do not obstruct the card's heatsink.
