If a demo or trial license expires, any active Write-Back SmartCache volumes will automatically revert to Write-Through mode. Data integrity is preserved, but performance will degrade until a valid license is reinstalled.
Requires a minimum of 1 GB Flash-Backed Write Cache (FBWC) to enable SmartCache.
If you are looking to get the top performance out of your HPE servers, securing a SmartCache license through the official HPE Support Center is the best first step.
Speeds up file retrieval metadata performance for thousands of concurrent users. 3. Seamless Integration and Zero-Downtime Deployment hp smartcache license key top
Drastically reduces query latency in Microsoft SQL Server and Oracle databases.
SmartCache automatically migrates your "hot data" (most frequently accessed data) to the SSD tier. To the operating system, the entire logical drive appears to run at SSD speeds, even though 80-90% of the data resides on cheap HDDs.
If your license key fails to register or operate properly, check the following common roadblocks: If a demo or trial license expires, any
Data is written directly to the fast SSD cache first, and the controller acknowledges the write immediately to the host application. The data is later flushed to the HDDs. This provides massive write acceleration but requires a battery-backed write cache (FBWC) to protect data against sudden power failures. 2. SSD Acceleration for Any Workload

Organizations requiring high performance should ensure proper hardware redundancy and backup strategies are in place, especially when using RAID 0 cache volumes where a single SSD failure could result in data loss.
HPE recommends sizing your SSD cache to represent roughly 10% to 20% of your total active bulk storage capacity. For example, if you have 5TB of active data on HDDs, dedicate a 500GB to 1TB SSD for caching.
