Priya smiled through the phone. “Code: . Type it into the CLI under ‘license add.’ You’ll get 30 days to find the real key. By then, you’ll wonder how you lived without SmartCache.”

HPE SmartCache was introduced to solve this by using high-speed Solid State Drives (SSDs) as a temporary landing zone for that "hot data". Instead of replacing every slow HDD with an expensive SSD, SmartCache lets administrators add just a few SSDs to act as an "accelerator".
SmartCache is typically supported on P-series hardware architectures across multiple ProLiant server generations: hpe smartcache license key
A separate license key is required for each physical Smart Array controller on which you want to enable caching.
While the SmartCache architecture is built directly into the firmware of supported HPE Smart Array controllers, the feature is locked by default. Activating it requires an entitlement token, which you register to receive a unique license key. Licensing Model
The requirement for a license varies by server generation and controller model: Priya smiled through the phone
Click Configure SmartCache , select your unconfigured SSDs, and assign them to act as the cache pool.

Ensure your controller is a "P-series" controller. "E-series" (Essential) controllers (like the E208i-a) and "B-series" (Software RAID) controllers do not support HPE SmartCache, regardless of licensing.

The controller writes data directly to the fast SSD cache pool and immediately tells the host operating system that the write is complete. The controller then writes that data to the slower HDDs in the background. This provides massive write performance gains. It requires a battery-backed or flash-backed write cache (FBWC) on the controller to prevent data loss during unexpected power outages. The HPE SmartCache License Key Explained
