• Key Concepts: 
  Dynamic tiering is a feature of SAP HANA that allows for the automatic movement of data between different storage tiers. This feature enables the system to optimize the storage of data based on its usage and importance. It also helps to reduce the cost of storage by allowing for the use of cheaper storage tiers for less frequently used data. 
  
  How to use it: 
  Dynamic tiering can be enabled in SAP HANA by setting up a tiered storage system. This involves setting up different tiers of storage, such as RAM, SSD, and HDD, and then configuring the system to move data between them based on usage and importance. The system can be configured to move data between tiers automatically or manually. 
  
  Tips & Tricks: 
  When setting up dynamic tiering, it is important to consider the cost of each tier and how frequently data will be accessed from each tier. This will help to ensure that the most cost-effective storage solution is chosen for each type of data. Additionally, it is important to monitor the performance of the system after dynamic tiering has been enabled to ensure that it is working as expected.
