Gigabyte Rounding feature permits the installation of a replacement drive that is
slightly smaller (within 1 gigabyte) than the remaining working drive.
This can be helpful in the event that a drive fails and an exact replacement model
is no longer available. For example, with the Gigabyte Rounding feature enabled,
the remaining working drive can be 80.5 GB and the replacement drive can be
80.3, since both are rounded down to 80 GB.
Number of Disk Drives
The number of disk drives you add to your logical disk depends on the number of
available channels on your FastTrak card and the type of logical disk you want to
create.
This chart shows your FastTrak Controller, the number of drives and the RAID
Levels it supports
This chart below shows the correlation between RAID Levels and the other
features and options:
New Drives versus Drives with Data
When you build a logical disk using new disk drives, you do not need to copy data
or perform quick initiation.
When you build a logical disk with disk drives that have been used before, but
you do not want to keep the data they contain, choose the quick initialization
option.
In some cases, you will have a disk drive full of data and want to make a mirror
(RAID 1) logical disk in order to have a full copy. See Add Fault Tolerance to
Existing Drive on page 30.
