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. The independent disk pool can be utilized only when it is needed.
• An independent disk pool in a clustered environment can provide disk storage that is switchable or replicated, allowing continuous availability of resources.
