Notes:
1. The default stripe size usually provides the best performance for
typical applications.
2. For RAID Level-6 and Level-60 logical drives, the number of choices
for stripe-unit size decreases as the number of disks in the logical
drive increases.
v
Read cache - Enables and disables read caching. When read-caching is enabled,
the controller monitors read access to the logical drive. If it detects a pattern, it
pre-loads the cache with the data that seems most likely to be read next. The
default is Enabled.
v Initialize method - Determines the method used to initialize the logical drive.
You can choose from three available methods:
– Auto-synchronization - For RAID Level-1 logical drives, copies the data
from the primary drive to the mirror drive. For RAID Level-5 logical drives,
computes and writes the correct parity for the entire logical drive.
Note:
Auto-synchronization can be a lengthy operation. The ServeRAID
Manager performs this task in the background. However, you cannot
use the logical drive until the task is complete.
– Clear - removes pre-existing data by overwriting every block in the logical
drive. This method is faster than auto-synchronization but the logical drive is
not available immediately.
For HostRAID controllers, the ServeRAID
Manager supports the Clear initialization method only.
– Quick - makes the logical drive available immediately. It is the fastest
method but should be used only for new physical disks.
v
Initialize priority - Adjusts the priority of the initialization task. The default is
High: initialize the logical drive as fast as possible.
When you are ready to continue, click Next. The Configuration Summary window
opens.

Use the configuration summary to review all the changes that the ServeRAID
Manager will apply to your configuration:
1.
Review the information that is displayed in the Configuration Summary
window. To change the configuration, click Back.
2. Click Apply; then, click Yes when asked if you want to apply the new
configuration. The configuration is saved in the integrated RAID controller.
Note: If you clicked Automatically initialize new logical drives, the ServeRAID
Manager will initialize the logical drives automatically.
