IBM 73P3984 Topspin InfiniBand 10Gbps Host Channel Adapter

Product Description

The IBM 73P3984 Topspin InfiniBand Host Channel Adapter is a critical component for building and expanding high-performance computing (HPC) clusters and other environments that demand extremely fast and low-latency interconnectivity. This adapter allows servers to connect directly to an InfiniBand fabric, which is specifically designed for high-bandwidth, message-passing communication patterns common in scientific simulations, financial modeling, and large-scale data analysis. Operating at a data transfer rate of 10Gbps, the 73P3984 ensures that data can be moved between compute nodes and storage systems with minimal delay. This is crucial for applications where the performance bottleneck is often network communication. The InfiniBand architecture offers features like remote direct memory access (RDMA), which allows one computer to access the memory of another computer directly without involving the operating system, further reducing latency and CPU overhead. As a Host Channel Adapter, this IBM product acts as the interface between the server's internal bus (typically PCI) and the InfiniBand network. It handles the complex protocols and signaling required for InfiniBand communication, offloading these tasks from the server's CPU. This makes the 73P3984 an essential piece of hardware for organizations leveraging HPC to accelerate research, development, and complex computational tasks.
