Modifying Cache Settings

You can modify the read and write cache settings for an array. You can also modify the maxCache settings. Adaptec maxCache uses the compatible Solid State Drives (SSDs) in your system as a fast read cache pool to improve performance in read-intensive applications.

Note: maxCache Read Caching is supported on Adaptec Series Q controllers only. For more information about maxCache, see Using the ACU to Manage the maxCache Pool on page 109.

To modify the cache settings for an array:

1Select Manage Arrays from the main ACU menu.

2Select the array, then press Ctrl+C.

The Modify Cache Settings window opens.

3Enable or disable read caching.

4Press Tab.

5Enable or disable write caching:

Select Enable always for “write-back” caching

Select Enable with ZMM if your controller has battery backup or a zero-maintenance cache protection module

Select Disable for “write-through” caching

6Press Tab.

7Select the maxCache Read Cache setting (Enable/Disable).

8Press Tab.

9Press Enter to accept the values.
