HPE P45645-001 InfiniBand NDR 400Gb/s PCIe 5.0 Adapter
Overview
The HPE P45645-001 is a high-performance network adapter designed to eliminate data bottlenecks in the most demanding computing environments. As a single-port 400Gb/s InfiniBand Host Channel Adapter (HCA), it is engineered for enterprise data centers, artificial intelligence (AI) clusters, and high-performance computing (HPC) systems. It directly addresses the need for extreme throughput and ultra-low latency, enabling servers to process and transfer massive datasets without CPU bottlenecks. This adapter leverages the power of the NVIDIA ConnectX-7 controller and the InfiniBand Next Data Rate (NDR) standard to achieve its 400Gb/s speed. Its PCI Express 5.0 x16 host interface provides the necessary bandwidth to the server's main bus, ensuring the network connection is never a limiting factor. Advanced hardware offloads for collective operations and reliable transport protocols free up valuable CPU cycles, allowing processors to focus on computation rather than network traffic management. Designed as a Half-Height, Half-Length (HHHL) PCIe card, the P45645-001 offers broad compatibility within modern server chassis, such as the HPE ProLiant Gen11 family. Its OSFP port provides robust, high-density connectivity to the InfiniBand fabric. Enhanced security features, including a Hardware Root of Trust and Secure Boot, protect the integrity of the hardware and firmware, providing a secure foundation for critical infrastructure.
