Questions & Answers
What is the HP Nimble Storage NS CS300/500/700 3.84TB Cache Field Upgrade (SKU Q8D02A)?
The HP Nimble Storage NS CS300/500/700 3.84TB Cache Field Upgrade (SKU Q8D02A) is an authorized field-installable cache module that adds 3.84 TB of FlashAccelerated Cache to CS300, CS500, and CS700 arrays for improved performance.
Which Nimble Storage models support SKU Q8D02A?
The Q8D02A 3.84 TB cache upgrade is fully compatible with Nimble Storage CS300, CS500, and CS700 arrays running the minimum required NimbleOS firmware.
What performance benefits does a 3.84 TB cache add to my CS series array?
Upgrading to a 3.84 TB cache increases IOPS, reduces application latency, and accelerates read/write operations by leveraging additional FlashAccelerated Cache capacity.
How do I install the NS CS300/500/700 3.84 TB Cache Field Upgrade?
Power down the array, insert the Q8D02A module into the designated cache slot, update firmware if prompted, and power on. The system automatically detects and configures the new cache.
Is professional installation required for the Q8D02A cache upgrade?
While experienced administrators can follow the Quick Install Guide, HP recommends using an HP-certified technician to ensure optimal configuration and minimize downtime.
Can I install multiple Q8D02A cache modules in one array?
No. Each CS300, CS500, or CS700 array supports a single 3.84 TB cache module; additional modules beyond the supported slot are not supported.
What pre-installation checks should I perform before upgrading cache?
Verify firmware compatibility, back up critical data, confirm stable power and network connections, and review the upgrade prerequisites in the Quick Install Guide.
How long does the cache upgrade installation take?
The entire process—shutdown, module insertion, and system reboot—typically completes in 15–20 minutes, depending on firmware update needs.
Will upgrading to 3.84 TB cache affect my warranty?
No. The Q8D02A cache field upgrade is fully supported by HP and does not void the existing Nimble Storage warranty or support agreements.
How do I verify the cache upgrade in my CS array?
After reboot, access the Nimble Storage HTML5 UI or run the CLI command “show flash-cache” to confirm the array recognizes the new 3.84 TB cache module.
What power and cooling requirements are needed for the Q8D02A upgrade?
The 3.84 TB cache module operates within the existing CS300/500/700 power and thermal specifications; no additional power or cooling modifications are required.
Does the cache upgrade require firmware updates?
Yes. Ensure your array runs the minimum recommended NimbleOS version. If not, perform a firmware update via the Nimble UI or CLI before installing the Q8D02A module.
How does the 3.84 TB cache upgrade impact latency?
Expanding to 3.84 TB of cache can reduce average read/write latency by up to 50% under mixed-workload conditions, improving application responsiveness.
Can I revert to the original cache configuration after upgrading?
Yes. To revert, power down the array, remove the Q8D02A module, and reboot. Document configuration settings before removal to maintain system stability.
What troubleshooting steps should I take if the cache upgrade fails?
Check module seating, verify firmware compatibility, review system logs via the Nimble UI, reseat the cache module, and contact HP Support with diagnostic logs if needed.
Is financing or trade-in available for the cache upgrade?
HP Financial Services offers flexible financing options, and you can leverage HP trade-in programs for credit toward your Q8D02A purchase when returning eligible legacy equipment.
Where can I purchase the SKU Q8D02A upgrade?
