781911-B21 Use Case
Enterprise Server Virtualization Consolidation with HPE DL380 Gen9 E5-2685v3 Kit
In a multinational financial services firm, IT operations faced server sprawl and rising infrastructure costs. By deploying the HPE DL380 Gen9 E5-2685v3 Kit as a virtualization host in an HPE OneView-managed data center, the firm consolidated 30 underutilized physical servers onto three 28-core DL380 Gen9 nodes. Outcome: 75% reduction in rack space, 60% lower power and cooling expenses, and simplified VM provisioning—delivering faster time-to-market for new financial applications while upholding enterprise-grade reliability.
Real-Time Big Data Analytics on HPE DL380 Gen9 E5-2685v3 Kit
A retail analytics provider needed sub-second insights into customer purchase behaviors during peak shopping seasons. Deploying an Apache Hadoop cluster on HPE DL380 Gen9 servers powered by dual Intel Xeon E5-2685v3 CPUs enabled 56 CPU cores and up to 3 TB of DDR4 memory per node. Outcome: 40% faster MapReduce job throughput, real-time dashboard updates for marketing teams, and scalable capacity to ingest terabytes of transaction data daily—driving targeted promotions and boosting conversion rates by 20%.
High-Performance Computing and AI Inference with HPE DL380 Gen9 E5-2685v3 Kit
A life sciences research lab required accelerated molecular modeling and deep learning inference for drug discovery. By integrating NVIDIA GPUs into HPE DL380 Gen9 chassis with the E5-2685v3 Kit as the CPU backbone, researchers ran parallelized simulations and TensorFlow workloads at scale. Outcome: 3× faster simulation cycles, 50% reduction in model training time, and robust error-correcting memory safeguards—enabling the lab to shorten new compound validation from months to weeks while ensuring compute integrity.
