In a global enterprise deploying VMware Horizon on HPE Nimble Storage CS and SF arrays, the Q8B64A-HPE NS CS/SF Hybrid 5.76TB Cache Bundle delivers sub-millisecond I/O response under peak login storms. By caching hot desktop images and read/write metadata, IT administrators reduce backend disk IOPS by up to 70%, shorten user login times by 50%, and maintain consistent SLA-driven performance across remote offices. The outcome is a seamless end-user experience, optimized storage utilization and predictable VDI scale-out.
A financial services firm running high-volume Oracle and Microsoft SQL databases on HPE Nimble Storage CS uses the Q8B64A-HPE NS CS/SF Hybrid 5.76TB Cache Bundle to accelerate critical OLTP transactions. By offloading frequent block reads and writes into the 5.76 TB hybrid cache layer, query execution times drop by 40% and concurrency spikes are absorbed seamlessly. This results in measurable improvements in transaction throughput, tighter compliance with peak-hour SLAs and reduced CPU overhead on database servers.
A large healthcare provider leverages the Q8B64A-HPE NS CS/SF Hybrid 5.76TB Cache Bundle in its HPE StoreOnce backup architecture to speed up daily full and incremental backups. Hot data segments are served directly from the hybrid cache, cutting backup windows by 50% and accelerating restore operations by 3×. The benefit is a more resilient data protection strategy, streamlined DR testing and consistent achievement of RPO/RTO targets without adding additional primary storage.

The HPE NS CS/SF Hybrid 5.76TB Cache Bundle (Q8B64A) is a certified cache acceleration package that combines high-capacity NVMe and SATA SSDs to boost HPE Nimble Storage and ProLiant server performance by off-loading hot data to a dedicated 5.76TB cache layer.
Key features include 5.76TB of hybrid SSD cache (NVMe and SATA), plug-and-play integration with HPE servers, automated data tiering, and full compatibility with HPE InfoSight predictive analytics for proactive optimization.
By storing frequently accessed (“hot”) data in high-speed SSDs, the cache bundle reduces latency, accelerates I/O operations, and optimizes mixed workload response times by up to 10× compared to traditional spinning disks.
The cache bundle is compatible with HPE ProLiant Gen10 and Gen11 servers equipped with a Smart Array controller that supports HPE SmartCache or HPE Cache accelerated controller functionality.
