Array Configuration Utility (ACU)
97Modular SAN Array 1000 User Guide
7. If the controller has an array accelerator, a screen is now displayed that lets
you disable it for the currently selected logical drive.
Choose whether to disable the array accelerator and click Next.
Note: Disabling the array accelerator for a logical drive reserves use of the accelerator
cache for other logical drives on the array that need to have the maximum possible
performance (such as those that contain database information).
The gray Configuration View window shows the configuration that you have
chosen.
8. Check that the configuration is acceptable and click Finish.

9. Click the Save icon to commit the changes to the controller and click OK on
the confirmation alert. (If you discard the changes, all changes since the
previous save are lost.)
To change the array configuration, refer to “Modifying an Existing Controller.”
