<h1 class="topictitle1">Disk pool uses</h1>
|
||
|
|
<div><p>Disk pools are used to manage system performance and backup requirements,
|
||
|
|
as follows:</p>
|
||
|
|
<ul><li>You can create a disk pool to provide dedicated resources for frequently
|
||
|
|
used objects, such as journal receivers.</li>
|
||
|
|
<li>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.</li>
|
||
|
|
<li>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.</li>
|
||
|
|
<li>You can create a disk pool to place infrequently used objects, such as
|
||
|
|
large history files, on disk units with slower performance.</li>
|
||
|
|
<li>You can use disk pools to manage recovery times for access paths for critical
|
||
|
|
and noncritical database files using system-managed access-path protection.</li>
|
||
|
|
<li>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.</li>
|
||
|
|
<li>An independent disk pool in a clustered environment can provide disk storage
|
||
|
|
that is switchable, allowing continuous availability of resources.</li>
