About SmartTier

Note: SmartTier is the expanded and renamed feature previously known as

Dynamic Storage Tiering (DST).

SmartTier matches data storage with data usage requirements. After data

matching, the data can then be relocated based upon data usage and other

requirements determined by the storage or database administrator (DBA).

As more and more data is retained over a period of time, eventually, some of that

data is needed less frequently. The data that is needed less frequently still requires

a large amount of disk space. SmartTier enables the database administrator to

manage data so that less frequently used data can be moved to slower, less

expensive disks. This also permits the frequently accessed data to be stored on

faster disks for quicker retrieval.
