Changing the Cache Settings of the Storage Subsystem


Note:

The lower the specified percentage in the Start flushing text box and the Stop flushing text box, the higher the chance that data for a read would require a disk read rather than be present in the cache. A lower percentage also increases the number of disk writes necessary to maintain the cache level, which increases system overhead and decreases performance.

  1. Select Storage Subsystem >> Change >> Cache Settings .
  2. Select the percentage of unwritten data in the cache to trigger a cache flush in the Start flushing text box.
  3. Select the percentage of unwritten data in the cache to stop a cache flush in progress in the Stop flushing text box.
  4. From the Cache block size list, select a cache block size that is appropriate for your applications. A smaller cache size is a good choice for file system use or database application use. A larger cache size is a good choice for applications that generate sequential I/O, such as multimedia.
  5. In the Enter Password dialog, type the current password for the storage subsystem, and click OK.
