Questions & Answers
What is the HPE NS CS/SF Hybrid 11.5TB Cache Upgrade (SKU Q8D01A)?
The HPE NS CS/SF Hybrid 11.5TB Cache Upgrade (SKU Q8D01A) is a factory-certified cache expansion kit that adds 11.5 TB of SSD-based cache to compatible HPE storage arrays for accelerated I/O performance.
Which HPE storage systems are compatible with SKU Q8D01A?
The 11.5 TB cache upgrade is fully compatible with HPE Nimble Storage CS Series, HPE 3PAR StoreServ 8000, and HPE StoreVirtual 3200 arrays running supported firmware releases.
What performance benefits does the 11.5 TB cache upgrade deliver?
By adding 11.5 TB of high-endurance SSD cache, customers can expect up to 2× higher random I/O throughput, sub-millisecond latency, and reduced backend disk activity for mixed workloads.
Does installing the Q8D01A cache upgrade require system downtime?
No downtime is required. The upgrade’s hot-pluggable SSD modules install while the array is online and automatically integrate into the existing cache pool.
What components are included in SKU Q8D01A?
The kit includes four 2.88 TB enterprise-grade SSD modules (totaling 11.5 TB), carrier trays, firmware-validated cables, and installation documentation.
How do I install the 11.5 TB cache upgrade?
Install each SSD module into an empty cache slot, verify firmware compatibility, then use the array’s management interface to add the new capacity to the cache pool.
Are firmware updates required before applying the cache upgrade?
Yes. Ensure your array is running the minimum firmware version specified in the release notes to guarantee full compatibility and performance.
Can I mix the new 11.5 TB cache modules with existing cache drives?
Yes. The array dynamically balances I/O across existing and new SSD cache modules as long as they share the same form factor and firmware revision.
How does the cache upgrade impact deduplication and compression?
All data reduction features remain fully operational; cache acceleration actually enhances inline dedupe and compression efficiency by reducing read/write latency.
Is the cache upgrade supported in clustered or multi-controller configurations?
Yes. The upgrade synchronizes cache data across controllers in clustered configurations to maintain high availability and data integrity.
What warranty and support are provided with SKU Q8D01A?
The cache upgrade carries HPE’s standard three-year parts, labor, and onsite support warranty, plus global technical assistance and access to software updates.
How do I order the HPE NS CS/SF Hybrid 11.5TB Cache Upgrade?
Contact your authorized HPE reseller or log into HPE’s online ordering portal, reference SKU Q8D01A, and specify your array model for compatibility verification.
What is the return policy for the cache upgrade kit?
Unopened and uninstalled kits can be returned within 30 days of delivery under HPE’s standard return merchandise authorization (RMA) policy.
How do I monitor cache performance after the upgrade?
Use the HPE storage management GUI or CLI to view real-time cache hit rates, I/O latency metrics, and utilization dashboards post-installation.
Does the cache upgrade integrate with HPE InfoSight analytics?
Yes. Once the SSD modules are installed, HPE InfoSight gathers cache performance data, provides predictive analytics, and offers proactive recommendations.
What ongoing maintenance is required for the additional cache?
No special maintenance is needed. The array’s automated firmware updates and health-check routines ensure optimal cache operation and reliability.
