Product Description
The NVIDIA MCX631102AN-ADAT is a high-performance ConnectX-6 Lx Ethernet Smart Network Interface Card engineered for modern, demanding data centers. This advanced network card delivers scalable, secure, and accelerated networking for 25 and 50 Gigabit Ethernet deployments, offering an optimal balance of performance and total cost of ownership. Supporting flexible configurations with dual 25GbE ports (SFP28) or a single 50GbE port (QSFP28), it provides up to 50Gb/s of total bandwidth. With PCI Express Gen4 x8 host connectivity, hardware-based security features, and comprehensive offload engines, this SmartNIC is essential for virtualized cloud infrastructures, enterprise applications, and high-performance computing clusters.
- High-Performance Connectivity: Dual-port 25GbE SFP28 or single-port 50GbE QSFP28 connectivity options
- Host Interface: PCI Express 4.0 x8 interface, backward compatible with PCIe 3.0
- ASAP² Technology: Accelerated Switch and Packet Processing offloads SDN/VNF data plane to the NIC
- Zero-Touch RoCE: Enables seamless deployment of RDMA over Converged Ethernet without complex network configuration
- Advanced Security: Hardware acceleration for inline IPsec encryption/decryption and stateful connection tracking
- Hardware Root of Trust: Provides supply chain security with secure boot and authenticated firmware updates
Built on foundational technologies including the ASAP2 engine for full offload of virtual switches and network functions, this SmartNIC supports encapsulation protocols including VXLAN, GENEVE, NVGRE, MPLS, and GTP. It implements RoCE v2 for high-efficiency data movement and features hardened security with inline IPsec engines. The card adheres to PCI-SIG specifications for PCIe Gen4 and supports standard management interfaces for comprehensive ecosystem compatibility.
The ConnectX-6 Lx SmartNIC operates as an intelligent network endpoint. Data packets are processed through the NIC's programmable parser, with network virtualization traffic handled entirely within the ASAP2 engine. RDMA/RoCE packets are placed directly into application memory via zero-copy operations, while secure traffic is encrypted or decrypted on-the-fly. All operations are performed in dedicated hardware engines, significantly offloading server CPUs and improving overall system efficiency.
- Hyperconverged Infrastructure & Virtualized Data Centers: Offloads virtual switching to improve VM density and performance
- Cloud Service Providers & Telco NFV: Accelerates virtual network functions and service chains
- High-Performance Computing & AI/ML Clusters: Provides low-latency, high-bandwidth connectivity
- Secured Enterprise Gateways & Storage Appliances: Utilizes hardware-accelerated IPsec for high-speed encrypted tunnels
- High-Frequency Trading & Financial Analytics: Delivers ultra-low latency and high message rates
