Chapter 3: FastBuild™ Utility

Gigabyte Boundary

The Gigabyte Boundary feature is designed for fault tolerant arrays (RAID 1, 0+1

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 80.5 GB drive would be rounded

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

replacement model is no longer available.

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 80.5 GB 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 drive in order to arrive at a common drive size.
