The Dell Validated Design for Government High Performance Computing (HPC), Artificial Intelligence (AI), and data analytics are workload-optimized rack-level systems based on building block options for compute, networking, and storage, with software to provide flexibility in design architecture. Given the convergence of HPC, AI and data analytics workloads, unified architectures based on the combination of scalable rack units are presented to optimize performance on both compute centric workloads and data centric workloads. Alternatively, architectures optimized for traditional HPC compute centric workloads, such as modeling and simulation, or architectures optimized for data analytics workloads are also presented to support customers who prefer dedicated systems. Benchmarked baseline designs serve as starting points for custom designs to meet specific customer requirements.
