4 Press the UP and DOWN arrow keys to select specic physical drives.
Press the Enter key to associate the selected physical drive with the cur-
rent RAID set.
It is recommend that you drives of the same capacity in a specic array.
If you use drives with different capacities in an array, all drives in the
raid set will be set to the capacity of the smallest drive in the raid set.
The numbers of physical drives in a specic array determines which RAID
levels that can be implemented in the array.
RAID 0 requires 1 or more physical drives.
RAID 1 requires at least 2 physical drives.
RAID (1+0) requires at least 4 physical drives.
RAID 3 requires at least 3 physical drives.
RAID 5 requires at least 3 physical drives.
RAID 6 requires at least 4 physical drives.
5 After adding the desired physical drives to the current RAID set, press
Yes to conrm the “Create Raid Set” function.
6 An “Edit The Raid Set Name” dialog box appears. Enter 1 to 15 alphanu-

10 Choosing Foreground (Fast Completion) or Background (Instant Avail-
ability) initiation: during Background Initialization, the initialization
proceeds as a background task and the volume set is fully accessible for
system reads and writes. The operating system can instantly access the
newly created arrays without requiring a reboot and waiting for initializa-
tion complete. In Fast Initialization, the initialization must be completed
before the volume set is ready for system accesses. In Fast Initialization,
initiation is completed more quickly but volume access by the operating
system is delayed.
11 If space remains in the raid set, the next volume set can be congured.
Repeat steps 8 to 10 to congure another volume set.
