HPE P45642-B21 InfiniBand NDR200 PCIe Gen5 Adapter
Overview
The HPE P45642-B21 is a high-performance InfiniBand and Ethernet adapter designed for demanding workloads in high-performance computing (HPC), artificial intelligence (AI), and enterprise data centers. This single-port adapter leverages NVIDIA ConnectX-7 smart host channel adapter (HCA) technology to deliver ultra-low latency and high bandwidth, solving critical data transfer bottlenecks in complex computational environments. It is engineered for seamless integration with HPE ProLiant, Apollo, and Cray servers. At its core, the adapter provides a robust solution for accelerating data-intensive applications. It utilizes the NVIDIA Quantum-2 InfiniBand architecture to achieve a throughput of up to 200Gb/s (NDR200), significantly reducing the time required for complex simulations and data analysis. Features like hardware-based congestion control and atomic operations ensure stable, scalable performance, making it a critical component for building next-generation AI and HPC clusters. Physically, the P45642-B21 is a PCIe 5.0 x16 plug-in card with a single OSFP port, ensuring maximum I/O throughput and compatibility with the latest server architectures. This form factor allows for straightforward installation in compatible HPE servers. Management is integrated within the HPE server ecosystem, with firmware updates available through standard HPE tools like iLO, providing a unified and secure management experience from a single point of contact.
