Q8B77A Use Case
Accelerate Virtual Desktop Infrastructure with HPE NS CS1000H Hybrid 480GB Cache Bundle
A global enterprise deploying 500 Citrix-based virtual desktops struggled with slow boot storms and inconsistent user experience. By integrating the Q8B77A-HPE NS CS1000H Hybrid 480GB Cache Bundle as a dedicated flash layer, login times dropped by 70%, IOPS spiked by 4× under peak load, and end-user productivity increased. The outcome: predictable, high-performance VDI delivery with up to 35% lower infrastructure costs.
Optimize OLTP Database Performance for Financial Services
A regional bank operating high-volume SQL Server transaction workloads faced latency spikes during quarter-end processing. Deploying the HPE NS CS1000H Hybrid 480GB Cache Bundle as a hot read/write cache accelerated transaction commits, reducing average query response from 25ms to under 10ms and cutting batch window by 45%. The result: faster reporting, tighter SLAs and improved customer satisfaction.
Boost Virtualization Consolidation in Mixed-Workload Data Centers
A mid-sized cloud provider consolidating VMware ESXi clusters onto hybrid arrays encountered performance bottlenecks under mixed VM workloads. Incorporating the Q8B77A cache bundle delivered sub-millisecond latency and sustained 150,000 IOPS per array, enabling 30% higher VM density and driving 20% savings in rack-space power and cooling. The benefit: scalable, cost-effective consolidation without compromising SLAs.
