HPE SmartCache is a controller-based software solution that accelerates application performance by caching "hot" data from Hard Disk Drives (HDDs) onto lower-latency Solid State Drives (SSDs) . While standard on some high-end controllers like the HPE Smart Array P816i-a SR Gen10
, it generally requires an optional, server-specific license for most ProLiant Gen8, Gen9, and Gen10 models. Hewlett Packard Enterprise Licensing Requirements and Options
To enable SmartCache, you must have one license per server. The license is non-transferable and typically includes one year of 24x7 technical support. Hewlett Packard Enterprise Single-Server License (LTU/E-LTU):
Used for a single server, delivered via a physical activation card or an electronic entitlement. Flexible-Quantity License:
Allows the purchase of multiple licenses under a single activation key for mass deployment. Activation Key Agreement:
A specialized program for customers planning to deploy licenses periodically over 1–3 years, paying only as they are used. Hewlett Packard Enterprise How to Obtain and Register Your Key
You do not receive the actual 25-character alphanumeric activation key immediately upon purchase; instead, you receive an Entitlement Certificate Google Groups Redemption: My HPE Software Center hpe smartcache license key
to redeem your certificate online using the Entitlement Order Number (EON). Retrieval:
Once redeemed, you can view your activation history and download the license key text file directly from the portal. Evaluation:
A 60-day trial key is often available for testing before a permanent purchase. Hewlett Packard Enterprise Activation Process Activation is performed through the HPE Smart Storage Administrator (SSA) GUI Method: Open HPE SSA, select your controller, navigate to the tab, and select Manage License Keys to add your new key. CLI Method: tool with the following syntax:
controller slot=0 add licensekey=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX Hardware Compatibility
Yes. If you have legacy HDD-based storage arrays but need modern performance for virtualization or database workloads, the HPE SmartCache license is the most cost-effective upgrade. For the price of a few high-endurance SSDs plus a $500 license, you can defer a $20,000 all-flash array purchase for 2-3 years.
Remember: The license key is the gatekeeper. Do not buy SSD hardware without budgeting for the license. Check your current entitlements in iLO first; sometimes, high-end server SKUs ship with an "Activated" SmartCache license pre-installed. HPE SmartCache is a controller-based software solution that
Need further assistance? HPE GreenLake support or your authorized reseller can verify your license entitlement using the Server Product Number (PN) and Serial Number (SN). Always run the latest controller firmware before attempting activation.
After the license is active, you can create the cache:
What is HPE SmartCache? HPE SmartCache is a feature available on HPE Smart Array Controllers (e.g., P-Series controllers like the P408i-a, P816i-a, etc.) that uses a portion of solid-state drive (SSD) capacity as a high-speed cache for frequently accessed data from larger, slower hard disk drives (HDDs) or SAS/SATA SSDs. This accelerates read and write performance without requiring a full SSD investment.
What is the License Key? The SmartCache feature is not enabled by default. It requires a paid, controller-specific software license key to unlock and activate the functionality on a compatible HPE Smart Array Controller.

SmartCache License: TrueCache Drive Count: 2 (if configured)Summary: The HPE SmartCache license key is a controller-locked, one-time purchase that unlocks SSD-based caching on compatible HPE Smart Array controllers, significantly boosting performance for HDD-based arrays without requiring full SSD storage. Always purchase the license through authorized HPE channels.
In the world of enterprise storage, the bottleneck is often the latency between the server’s processor and the data storage. HPE SmartCache is a controller-based caching solution designed to solve this problem, but it requires activation via a license key to unlock its full potential.
