878655-B21 Use Case
Enterprise Virtualization Consolidation with HPE ML350 Gen10 & Xeon-P 8156
In a mid-sized financial services firm running 50+ virtual machines, IT deployed the 878655-B21 HPE ML350 Gen10 equipped with the Intel Xeon-P 8156 to consolidate legacy servers. The result: 2× improvement in VM density, 30% reduction in rack space and power consumption, and unified management via HPE OneView. This high-performance setup delivers rock-solid uptime, simplified patch cycles, and lower TCO for mission-critical operations.
AI Inference Edge Deployment for Retail Analytics
A national retail chain implemented the HPE ML350 Gen10 8156 Xeon-P Kit at 100+ store locations to process real-time customer-behavior analytics on-premises. Localized inferencing on video streams yields sub-second insights on foot traffic, product engagement, and checkout bottlenecks. Benefits include 25% lift in promotional targeting accuracy, GDPR-compliant data security at the edge, and centralized dashboard visibility across all sites.
Secure Virtual Desktop Infrastructure (VDI) for Hybrid Workforces
A global consultancy leveraged the HPE ProLiant ML350 Gen10 with Xeon-P 8156 to host 1,200 secure VDI sessions for remote and office-based professionals. Utilizing HPE iLO 5 and silicon root of trust, the deployment achieved PCI-DSS compliance plus 40% faster desktop boot times compared to prior hardware. The outcome: seamless collaboration, robust endpoint protection, and scalable performance under peak loads.
