Q8D48A Use Case
Accelerated VDI Deployments for Global Enterprises
In a multinational law firm deploying 3,000 virtual desktops across three data centers, the Q8D48A-HPE NS CS420G-X4 Kit—featuring dual x4 controllers, redundant PSUs, NVMe SSD caching and high-capacity HDDs—delivers sustained 15,000 IOPS at sub-millisecond latency. Outcome: 50% faster user log-on times, 35% reduction in storage footprint and centralized lifecycle management via HPE InfoSight.
High-Throughput Analytics and Machine Learning
A financial services company processes 10 TB of trading data nightly and trains predictive models on the same window. By leveraging the Q8D48A-HPE NS CS420G-X4 Kit’s 10 GB/s sequential throughput and 500K random IOPS, data-prep is cut from 4 hours to 90 minutes and model training accelerates by 60%. Outcome: faster insights, scalable growth and lower TCO.
Scalable Enterprise Backup & Disaster Recovery
A global manufacturer integrates the Q8D48A-HPE NS CS420G-X4 Kit with HPE StoreOnce for on-prem backup of 200 TB. Advanced deduplication (20:1 ratio), snapshot orchestration and automated failover deliver an RTO under 10 minutes and 40% shorter backup windows. Outcome: robust DR readiness, simplified management in HPE OneView and predictable scalability.
