Change cache settings for the storage array

For all volumes in the storage array, you can adjust the cache memory settings for flushing and block size.

About this task

Cache memory is an area of temporary volatile storage on the controller, which has a faster access time than the drive media. To tune cache performance, you can adjust the following settings:


  1. Select Settings > System.
  2. Scroll down to Additional Settings, and then click Change Cache Settings.
    The Change Cache Settings dialog box opens.
  3. Adjust the following values:
    • Start demand cache flushing – Choose a percentage that is appropriate for the I/O used in your environment. If you choose a value lower than 80%, you may notice decreased performance.
    • Cache block size – Choose a size that is appropriate for your applications.
  4. Click Save.
