Using disk pool

 

Disk pools are used to manage system performance and backup requirements.

System performance and backup requirements:

• You can create a disk pool to provide dedicated resources for frequently used objects, such as journal receivers.

• You can create a disk pool to hold save files. Objects can be backed up to save files in a different disk pool. It is unlikely that both the disk pool that contains the object and the disk pool that contains the save file will be lost.

• You can create different disk pools for objects with different recovery and availability requirements. For example, you can put critical database files or documents in a disk pool that has mirrored protection or device parity protection.

• You can create a disk pool to place infrequently used objects, such as large history files, on disk units with slower performance.

• You can use disk pools to manage recovery times for access paths for critical and noncritical database files using system-managed access-path protection.

• An independent disk pool can be used to isolate infrequently used data in order to free up system resources to be utilized only when it is needed.

• An independent disk pool in a clustered environment can provide disk storage that is switchable, allowing continuous availability of resources.
