Initialization ― Data on all drives is set to zero, erasing the disks.

Gigabyte Boundary ― The Gigabyte Boundary feature is designed for

fault tolerant arrays (RAID 1, 0+1, 3 and 5) in which a drive has failed

and the user cannot replace the drive with the same capacity or larger.

Instead, the Gigabyte Boundary feature permits the installation of a

replacement drive that is slightly smaller (within 1 gigabyte) than the

remaining working drive (for example, an 80.5GB drive would be

rounded down to 80GB). This can be helpful in the event that a drive fails

and an exact replacement model is no longer available. Without this

feature enabled, UltraTrak will NOT permit the use of a replacement

drive that is slightly smaller than the remaining working drive.

For the Gigabyte Boundary feature to work, the Gigabyte Boundary

feature must be set to ON when the original array is created. When

enabled, the Gigabyte Boundary feature rounds the drive capacity of all

drives to the common whole GB drive size. For example, with the

Gigabyte Boundary feature enabled, the remaining working drives can

be 80.5GB and the replacement drive can be 80.3, since all are rounded

down to 80GB. This permits the smaller drive to be used. Please note

that users will lose a small amount of available storage capacity from

each drives in order to arrive at a common drive size.
