Product Description

The HP 829911-B21 is a high-radix, high-performance switch built upon Intel's Omni-Path Architecture (OPA), specifically engineered for demanding High-Performance Computing (HPC) environments. It offers 48 ports of 100 Gigabit Ethernet (100GbE) using QSFP28 transceivers, providing massive bandwidth and extremely low latency crucial for tightly coupled parallel processing and data-intensive scientific simulations. The Omni-Path fabric is designed to deliver superior performance compared to traditional Ethernet or InfiniBand solutions for specific HPC workloads, offering sub-microsecond latency and high message rates. This switch is a cornerstone for building scalable HPC clusters. Its high radix design allows for efficient and dense fabric topologies, minimizing the number of hops between compute nodes and maximizing communication efficiency. The non-blocking architecture ensures that all ports can operate at their full 100GbE speed simultaneously, providing consistent performance for all connected systems. It is optimized to work seamlessly with Intel Omni-Path Host Fabric Interfaces (HFIs) installed in servers, creating a cohesive and high-performance interconnect solution. The 829911-B21 switch is designed for reliability and efficiency in large-scale deployments. It supports advanced fabric management tools and diagnostics, enabling administrators to monitor and optimize the performance of the HPC cluster. The low power consumption per port makes it an energy-efficient choice for large deployments, contributing to lower operational costs in data centers. Its robust construction and advanced features make it suitable for the most demanding scientific research, financial modeling, and AI/ML training workloads.
