Q8B64A Use Case
Accelerating VMware Horizon VDI with Q8B64A-HPE NS CS/SF Hybrid 5.76TB Cache Bundle
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.
Boosting Transactional Database Throughput on HPE Nimble Storage
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.
Optimizing Backup & Restore Workflows with Hybrid Cache Acceleration
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.

Questions & Answers
What is the HPE NS CS/SF Hybrid 5.76TB Cache Bundle (SKU: Q8B64A)?
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.
What are the key features of the Q8B64A cache bundle?
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.
How does the 5.76TB cache improve storage performance?
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.
Which HPE servers support the Q8B64A cache bundle?
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.
How do I install the HPE NS CS/SF Hybrid 5.76TB Cache Bundle?
Installation is tool-less: insert the SSD modules into designated Smart Array slots, enable SmartCache in the HPE Integrated Lights-Out (iLO) or HPE Smart Storage Administrator, and assign cache capacity to your storage pool.
Does the Q8B64A bundle include NVMe SSDs?
Yes, the bundle comprises a mix of enterprise-grade NVMe and SATA SSDs to deliver a balanced hybrid cache tier optimized for both high throughput and cost efficiency.
What is the warranty coverage for the Q8B64A cache bundle?
HPE provides a standard three-year parts, labor, and on-site support warranty for the Q8B64A bundle, with options to extend support and services through HPE Pointnext Care.
Can I upgrade from a smaller cache bundle to 5.76TB?
Yes, existing HPE SmartCache customers can seamlessly upgrade to the 5.76TB bundle by purchasing Q8B64A and updating cache settings in the HPE Smart Storage Administrator without data migration.
How does this bundle integrate with HPE Nimble Storage?
The cache bundle interfaces with HPE Nimble Storage arrays via the HPE InfoSight platform, automatically tiering hot data into the cache layer for accelerated throughput and predictive analytics.
What are the power and cooling requirements?
The Q8B64A SSD modules draw up to 12W each under load and require standard HPE server airflow. No additional power supplies or cooling infrastructure are needed beyond the server’s existing specs.
How does the hybrid cache differ from an all-flash solution?
A hybrid cache uses a combination of NVMe and SATA SSDs to optimize cost and performance, whereas all-flash solutions rely solely on NVMe or SAS SSDs, offering higher performance but at a premium price.
Is the Q8B64A bundle covered by HPE support and updates?
Yes, the cache bundle is supported under HPE ProLiant and HPE Nimble Storage support contracts, including firmware updates, hardware replacement, and technical assistance through HPE Care Pack services.
Are any software licenses required to use the cache bundle?
No additional software licenses are required beyond the HPE Smart Storage Administrator and the SmartCache feature, which are included with qualifying HPE ProLiant servers and storage controllers.
How does the cache bundle accelerate virtualization workloads?
By caching frequently accessed virtual machine files and metadata, the bundle reduces read/write latency, improves boot storm performance, and scales VDI environments with consistent I/O responsiveness.
What components are included in the Q8B64A package?
The bundle includes four 1.92TB NVMe SSD modules, two 384GB SATA SSD modules, carrier sleds for HPE ProLiant servers, and a QuickSpecs installation guide.
Are firmware and driver updates available for the cache bundle?
Yes, HPE regularly releases firmware and driver updates for the Q8B64A modules via the HPE Support Center, ensuring optimal compatibility and performance with ProLiant servers and storage controllers.
