HPE P47642-001 InfiniBand NDR200 PCIe Gen5 Adapter
Overview
The HPE P47642-001 is a high-performance network adapter designed for demanding high-performance computing (HPC) and artificial intelligence (AI) workloads. As a single-port InfiniBand adapter, it provides servers with an ultra-low latency, 200Gb/s NDR (Next Data Rate) interconnect. It is engineered specifically for deployment in data-intensive environments such as scientific research, large-scale data analytics, and machine learning clusters where rapid and efficient data transfer is critical to application performance. At its core, this adapter leverages the NVIDIA ConnectX-7 controller and the PCIe 5.0 x16 host interface to eliminate communication bottlenecks. This combination ensures that the full 200Gb/s bandwidth can be delivered to the host system, enabling faster computational cycles and reducing the time to solution for complex simulations. Key features like RDMA (Remote Direct Memory Access) and hardware-based congestion control offload the CPU, freeing up system resources to focus on computation rather than network transport management. Designed as a PCIe standup card with an OSFP (Octal Small Form Factor Pluggable) connector, the P47642-001 is validated for installation in supported HPE ProLiant, Apollo, and Cray server platforms. This ensures seamless integration and unified support within an HPE ecosystem. Its primary role is to form the foundational network fabric that connects compute nodes and storage systems, providing the scalability and performance required to build and expand powerful, efficient supercomputing and AI infrastructures.
