After determining that a new tier of SSD drives should be installed in the HPE 3PAR StoreServ 8400, the following actions should be recommended:
Configure Adaptive Optimization (AO): AO automatically moves data between storage tiers based on real-time I/O patterns. By configuring AO, the most frequently accessed data will be moved to the new SSD tier, optimizing performance and improving efficiency.
Configure scheduled tunesys tasks: Tunesys is a command used to optimize the storage layout on the HPE 3PAR array. By scheduling regular tunesys tasks, the data is redistributed across the available drives, ensuring that the array maintains optimal performance as the storage environment evolves.
