If the controller's FBWC capacitor is charging, degraded, or dead, SmartCache may automatically disable itself to prevent data loss. Check the battery health status inside HPE iLO or SSA.
Integrated into the SR (SmartRAID) controller architecture, such as the P408i-a, P408i-p, P408e-p, and P816i-a.
HPE occasionally provides 60-day trial keys. These allow system administrators to benchmark performance improvements in their specific environment before committing to a capital purchase. How to Obtain and Activate Your HPE SmartCache License Key
Press during POST to enter Intelligent Provisioning , or press F9 / F11 to access the boot options and select HPE Smart Storage Administrator .
Supported on Smart Array P440, P441, P840, and P841 controllers.
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".
The physical License to Use (LTU) includes:
All write operations are written directly to the bulk storage HDDs.
Configure the cache SSDs in a RAID array (such as RAID 1 or RAID 5) within the SmartCache settings. If a single un-cached SSD fails during write-back mode, data corruption will occur. Optimization Tips
“Anything.”
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.
: A small storage segment on the controller that maps data locations across HDDs and SSDs. 2. Licensing Requirements and Lifecycle
