Product Description
The HP 825318-B21 is a cutting-edge InfiniBand network adapter engineered to deliver unparalleled performance for the most demanding computational tasks. Featuring dual ports capable of 100 Gigabit Ethernet (GbE) speeds, each utilizing QSFP28 connectors, this adapter provides massive bandwidth essential for High-Performance Computing (HPC), artificial intelligence (AI) training, and large-scale data analytics. The adapter connects to the host system via a PCIe Gen4 x16 interface, ensuring that the network's high throughput is not bottlenecked by the system interconnect. This adapter is built to provide extremely low latency, a critical factor in tightly coupled parallel processing environments where fast communication between nodes is paramount. It supports advanced networking protocols and features, including RDMA (Remote Direct Memory Access), which allows applications to bypass the operating system kernel for direct memory-to-memory transfers, significantly reducing latency and CPU utilization. This capability is crucial for accelerating applications that rely on inter-process communication. Designed for integration into HPE server platforms, the 825318-B21 is a key component for building next-generation data centers and research clusters. Its ability to handle massive data flows and provide near-instantaneous communication makes it ideal for workloads such as complex simulations, deep learning model training, and real-time data processing. The adapter represents a significant leap in network connectivity, enabling breakthroughs in scientific research and enterprise innovation.
