Fine-tuning your configuration
Before you store data on the controller, you will need to determine the correct
stripe-unit size for your configuration and set the write-cache mode, if necessary.
Changing the stripe-unit size
The new controller stripe-unit size is set at the factory to 8 KB. If you need to
change this setting, you
must change the stripe-unit size before you store data in
the logical drives. After you store data in the logical drives, you cannot change the
stripe-unit size without destroying data in the logical drives.
Complete the following steps to change the stripe-unit size:
1. In the ServeRAID Manager tree, click the new controller to select it.
2. Click
Actions → Change stripe-unit size .
