2.1.6 Flexible Exascale Storage Pool Management

Starting with Oracle Exadata System Software release 26.1.0, you can create multiple storage pools for each media type within a single Exascale cluster. Previously, only one storage pool was permitted for each media type in an Exascale cluster.

In conjunction with this new capability, you can also:

• Provision an Exascale vault with specific storage resources from multiple storage pools using the same media type.

• Specify, either directly or indirectly using a template, the storage pool that contains a newly created file.

• Configure a single database with multiple storage pools of the same media type, enabling more precise placement of different database files or tablespaces.

• Move database data between storage pools online using Automatic Data Optimization (ADO).

These new capabilities provide more flexibility in using and managing Exascale storage resources, facilitating versatile data placement, and precise control of where data resides.

For example, if your Exadata environment includes both older and newer storage servers, you can create separate storage pools for each group. You can then map separate tablespaces to each pool and use ADO features in Oracle AI Database to define policies that place older or less frequently accessed data on the older servers, while keeping the most active data on the newer, higher-performance storage.
