While the physical hardware architecture supports caching, the functionality is locked within the Smart Array controller firmware.
In the modern data center, the bottleneck is rarely the processor; it is almost always the storage latency. While SSDs have revolutionized speed, high-performance NVMe drives remain expensive, and relying solely on HDDs for capacity creates significant performance drags.

If you are planning a deployment, ensure you have the license key entitlements ready to unlock the full potential of your Smart Array controllers. : Optional for P408 and P416 controllers; standard
Smart Cache is licensed per physical Smart Array controller, not per server or per hard drive. If a server has two P-series controllers and you want caching on both, you will need two separate license keys.
| Technology | Purpose | License Required | Key Differentiator | | :--- | :--- | :--- | :--- | | | Cache HDD "hot" data to SSDs for acceleration | Yes (optional) | Targeted acceleration in mixed HDD/SSD environments | | HPE SSD Smart Path | High-speed I/O path between controller and SSD | No (standard feature) | Optimizes performance when SSDs are primary storage | | HPE Secure Encryption | Encrypt data-at-rest on controller-attached storage | Yes (optional) | Compliance and data protection for sensitive data | | Standard FBWC | Basic controller cache for write buffering | No | Improves general write performance, no selective "hot" data caching |
While the Smart Cache architecture is built into the firmware of supported Smart Array controllers, it remains locked until a valid license key is applied. Supported Hardware
:
Please generate and provide the corresponding activation key(s) . The key must be compatible with [OS & HPE Smart Array Controller firmware version, if known].
The activation process involves two primary phases: obtaining the functional key from HPE, and applying it to your controller hardware. Phase 1: Retrieve Your License Key from the HPE Portal
If your server contains multiple controllers and you want caching on both, you will need a separate license key for each.
