About the NVIDIA MCX631432AN-ADAB ConnectX-6 VPI Adapter
Transport offload capabilities including RDMA (RoCE v1/v2), checksum offload, and tag matching define the NVIDIA MCX631432AN-ADAB ConnectX-6 VPI Adapter, a high-performance single-port network interface card engineered for next-generation data center architectures. This PCIe 4.0 x16 adapter delivers unified support for InfiniBand HDR, 100GbE, and 200GbE protocols, enabling organizations to consolidate storage, compute, and AI workloads on a single fabric. With a maximum data rate of 200 Gb/s and GPUDirect RDMA support, the MCX631432AN-ADAB eliminates CPU bottlenecks in GPU-accelerated and memory-intensive applications while maintaining a low-profile form factor suitable for space-constrained server environments.
Network architects and IT procurement teams evaluating high-speed interconnects will find this NVIDIA adapter particularly valuable for NVMe-oF deployments and RDMA-accelerated workloads. The QSFP56 connector provides future-proof optical transport, while SR-IOV support enables efficient virtual machine access in hyperscale environments. Comprehensive driver support across Linux, Windows Server, and VMware ESXi—via NVIDIA OFED and inbox drivers—ensures rapid deployment. Operating across 0°C to 55°C, this adapter integrates seamlessly into demanding production infrastructure without thermal constraints.
Enterprise Deployment Scenarios
- High-frequency trading and financial analytics clusters requiring sub-microsecond latency via RoCE v2 RDMA
- GPU-accelerated AI and machine learning training, leveraging GPUDirect RDMA to bypass system memory
- NVMe-oF storage networks for disaggregated data center architectures
- Virtualized cloud environments utilizing SR-IOV for guest VM network isolation and performance
- Large-scale distributed computing frameworks requiring 200 Gb/s InfiniBand HDR connectivity
