Selecting Array Type
Under the Definition section of this menu, highlight the Array # for which
you want to assign a RAID level.
Use the [Space] key to cycle through three array types: Performance
(RAID 0 Striping), Security (RAID 1 Mirroring, RAID 0+1
Striping/Mirroring (for 4 drives), or Capacity (Spanning). See page xx
about RAID levels.

Selecting Stripe Block
For RAID 0 Striped arrays only, you may manually select the
“stripe block size.” Use the Spacebar to scroll through choices
progressing as follows (1, 2, 4, 8, 16 . . . 1024).
The size selected affects how FastTrak100 sends and retrieves
data blocks from the drives. You will need to perform your own
testing to determine how the data block size is affecting your
particular use of the array. In general, a larger block size is
better when handling large data transfers (such as in A/V editing
or graphics) while a smaller block size is better when handling
e-mail and other common server data. The default is 64K.

] keys.
2. With the [Space] bar key, change assignment option to “Y” to add
the drive to the disk array.
3. Press <Ctrl-Y> to save the disk array information. Depending on the
array type selected, the following scenarios will take place:
(a) If choosing a Striping, Spanning, or Mirroring/Striping array, the
initial Define Array Menu screen will appear with the arrays defined.
From there you may ESC to exit and return to the Main Menu of
FastBuild.
(b) If you selected a Mirroring array for two drives, there is an
additional window that appears as described in order to create the
array. To do this you will use either two brand new drives, or one
drive that contains existing data that you wish to mirror.
Creating A Mirrored Array Using New Drives
As described in the Drive Assignments Option section above, if
you selected a mirroring array and wish to use two new
assigned drives, follow the directions here.
1. After assigning new drives to a Mirroring array and saving the
information with <Ctrl-Y>, the window below will appear.
Do you want the disk image to be duplicated to another?
(Yes/No)
Y - Create and Duplicate
N - Create Only
2. Press “N” for the Create Only option.
3. A window will appear almost immediately confirming that your
Security array has been created. Press any key to reboot the system
Array has been created.
