Creating a RAID 0 Array
In the Definition Menu section (see Figure 10), use the [Space] key to cycle
through array types and select "RAID 0" for RAID Level. You will be joining the
drives you assign to this array together and splitting (or striping) data writes among
the members of the array. Each member of such an array will no longer be
readable as an independent drive if removed from the array. The capacity of the
array will equal the capacity of the smallest drive multiplied by the number of drives
within the array.
Changing Stripe Block Size
For RAID 0 arrays, SuperTrak66 will allow you to change the stripe block
size. The default is 64K. However, certain application environments may
perform optimally with different values (see drive manufacturer for additional
information on block sizes). To change the block size, use the arrow keys
to highlight the field and the spacebar to cycle through the available size
selections.
Assigning Drives to a RAID 0 Array
Under the [ Drive Assignments ] section, highlight a drive and, with the
[Space] bar, change the Assignable option to “Y” to add the drive to the
disk array. Press
Define Array Menu screen will appear after you have pressed [Ctrl-Y]. You
will see the array defined. You may select another Array number to define
OR you may ESC to exit and return to the Main Menu of SuperBuild.
Creating a RAID 1 Array
In the Definition Menu section, use the [Space] key to cycle through array types
and select "RAID 1" for RAID Level. You will be creating two drives or two pairs of
striped drives (4 drives total) with identical data on them. The capacity of the array
will be half that of the total number of mirrored drives within the array. No stripe
block size option is available when mirroring 2 drives. In a 4-drive RAID 0+1 array,
you can set the stripe size for the two pairs of striped drives.
If you are creating a Mirroring array containing two drives only, you will use either
two brand new drives, or one drive that contains existing data and a second drive
that you wish to mirror data. There is an additional window that will appear in order
to create such an array.
Creating a Mirroring Array with Two New Drives
As described above, if you select a mirroring array and wish to use two
new assigned drives, follow the directions here. Under the [ Drive
Assignments ] section, assign both new drives to the array and save the
information with
create the array. Confirm “N” or “Create Only” to the message shown in
order to proceed.
