Gigabyte Boundary
The Gigabyte Boundary feature is designed for fault tolerant arrays RAID 1 (Mirror)
in which a drive has failed, and the user cannot replace the drive with a drive of the
same capacity or larger. This feature permits the installation of a replacement drive
that is slightly smaller than any remaining working drive (e.g. a 20.50GB drive would
be rounded down to 20GB). This can be useful if a drive fails and an exact replace-
ment is no longer available. Without this feature enabled, The Promise RAID con-
troller will NOT permit the use of a replacement drive the is slightly smaller than the
remaining working drive.
Stripe Block
The Promise RAID Controller will allow you to change the stripe block size for RAID
0 Arrays. To change the block size, use the arrow keys to highlight the field and the
<Spacebar> to cycle through the available size options (16, 32, 64 or 128K). Note
you cannot change the block size after the Array has been created.
Assigning Drives to an Array
Highlight a drive under Drive Assignments using the <Spacebar>, and change
the assignment option to "Y" to add the drive to the disk array. Press <Ctrl> + <Y>
to save the information.
