Questions & Answers
What is the HPE NS CS/SF Hybrid 2.88TB Cache Upgrade?
The HPE NS CS/SF Hybrid 2.88TB Cache Upgrade (SKU Q8C99A) is a high-performance flash module designed to accelerate read/write operations by adding 2.88 TB of SSD cache to supported HPE CS and SF storage arrays.
Which HPE storage arrays are compatible with the 2.88TB cache upgrade?
This cache upgrade is compatible with HPE StoreEasy CS-Series and StoreFabric SF-Series hybrid arrays that support NVMe or SAS-based flash caching, as specified in the HPE Storage Compatibility Matrix.
How does the 2.88TB cache upgrade improve system performance?
By storing hot data in ultra-low-latency SSDs, the 2.88 TB cache module reduces I/O wait times, improves throughput by up to 3×, and delivers consistently faster application response.
Is the HPE NS CS/SF 2.88TB cache upgrade easy to install?
Yes. The cache module is hot-swappable and installs in minutes using standard HPE tool-less drive bays, with automatic recognition and configuration via the HPE storage management console.
What flash technology powers the 2.88TB cache module?
The cache upgrade uses enterprise-grade, high-endurance NVMe SSDs with multi-level cell (MLC) architecture, optimized for sustained performance and reliability in hybrid storage environments.
Does the cache upgrade support data optimization features?
Yes. When paired with HPE InfoSight, this module leverages automated tiering, inline deduplication, and compression to maximize usable cache capacity and reduce data footprint.
What warranty and support cover the HPE NS CS/SF 2.88TB cache?
The cache upgrade carries a one-year HPE limited warranty with options to extend support to three or five years, including 24×7 HPE Foundation Care for rapid fault resolution.
Can I mix the 2.88TB cache module with other cache sizes?
No. HPE recommends installing identical cache modules to maintain balanced performance and avoid cache-pair mismatches that could degrade system efficiency.
How does HPE ensure data integrity in hybrid cache mode?
HPE uses error-correcting code (ECC), power-loss protection, and real-time parity checks to safeguard cached data, automatically flushing writes to persistent storage in case of power events.
What are the power and thermal requirements of this cache upgrade?
The 2.88 TB NVMe cache draws 8 W maximum and operates between 0 °C and 40 °C, fitting standard HPE chassis cooling and power budgets without additional infrastructure changes.
Will the cache upgrade work with existing HPE Nimble Storage arrays?
No. This module is specifically engineered for HPE CS-Series and SF-Series products and is not supported on Nimble Storage or 3PAR arrays.
How can I monitor cache usage and performance metrics?
Use the HPE Storage Management Console or InfoSight dashboard to view real-time cache hit rates, latency charts, and capacity utilization, with customizable alerts for thresholds.
What return on investment can I expect from a 2.88TB cache upgrade?
Organizations typically see ROI within six months through reduced application latency, lower core count licensing costs, and deferred storage capacity expansions.
Does installing the cache upgrade require a firmware or software update?
Yes. Ensure your array is running the minimum validated firmware version (listed in release notes) and the latest HPE OneView or InfoSight agent for seamless cache activation.
Where can I purchase the HPE NS CS/SF Hybrid 2.88TB Cache Upgrade?
You can order SKU Q8C99A through authorized HPE channel partners, the HPE online storefront, or by contacting your HPE account representative for enterprise pricing.
