Disk Array Parameters

3.3.1 Rebuild Priority
Rebuilding time will depend on the capacity of the logical drive. The
ASUS PCI-DA2100/-DA2200 RAID controller provides background
rebuilding ability. Meaning, the controller is able to serve other I/O
requests while rebuilding the logical drives. The rebuilding process is
totally transparent to the host computer or the operating system.
The background rebuild process has four priority options:
Low
Normal
Improved
High
The default priority is "Low" which uses the controller's minimum
resources to rebuild. Choosing "Normal" or "Improved" will
speedup the rebuilding process and choosing "High" will use the
controller's maximum resources to complete the rebuilding process
at the shortest time.
Rebuild priority can be configured through either the Text RAID
Manager or the GUI RAID Manager.
3.3.2 Verify-after-Write
The controller has the ability to force the hard drives to verify after
data has been written to the media of the HDD. There are three
selectable methods:
Verification on LD Initialization Writes
Performs Verify-after-Write while initializing the logical drive.
Verification on LD Rebuild Writes
Performs Verify-after-Write during the rebuilding process.
Verification on LD Normal Drive Writes
Performs Verify-after-Write during normal I/O requests.
Each method can be enabled or disabled individually. Hard drives
will perform Verify-after-Write according to the selected method.
