NOTE:
1. To reduce the chance of losing data, ALi imposed limitations on the
RAID configuration options. For example, Parallel-
A
TA drives
connected on the same IDE channel cannot be selected as the
members of a RAID1 array. Mixing Parallel- and Serial-
A
TA disk drives
in a RAID1 array should also be avoided.
2.
A
lways use disk drives of the same capacity to create a RAID array.
The excessive capacity of a larger disk drive cannot be utilized
because data mirrors are equally distributed across corresponding
members of drive pairs within a RAID array. The operational concept is
diagrammed below.
2.3 Create JBOD for Integrated Capacity
Step 1. JBOD stands for “Just a Bunch of Drives.” JBOD provides neither
performance gains nor data redundancy. To create a JBOD array, use
your arrow keys to highlight and press Enter to activate this item. A ‘J’
flashing character will appear at the Drive Selection Menu where you can
choose the member drives to be included in the JBOD.
Step 2. Use the Space key to select members of the JBOD configuration. The
flashing cursor should change to a lower case ‘j’ character once any of the
connected disk drives has been selected. Follow the same method to
select another member drive. The maximum number of member drives in
a JBOD is four and the minimum is two.
Step 3. You should then be prompted by a “Create RAID1(Y/N)” confirm box.
Step 4. Press Y and then some necessary information will be written to the
selected disk drives.
