We can also remove a disk from the volume by clicking on the
Remove
button. The volume will
still be available but in a non-redundant state. An additional disk failure would render this volume
unusable.
Warning
The Remove operation is a maintenance feature and is not recommended in
a live environment. Its function is equivalent to hot-removing the disk or
simulating a disk failure.
The
Locate
option is a way to verify that a disk is correctly situated in the expected disk slot.
Clicking on
Locate
will blink the LED of the disk for 15 seconds.
Volume Management for X-RAID
The X-RAID technology offers a simplified approach to volume management. X-RAID works on
the premise that what most people want to do with their data volume over time is either adding
redundancy or expanding it without the headaches usually associated with doing that. By using
simple rules, X-RAID is able to hide all the complexities yet provide volume management features
only previously available in enterprise-level storage solutions.

X-RAID REDUNDANCY OVERHEAD
To maintain redundancy from disk failure, X-RAID requires a one-disk overhead. In a two-disk X-
RAID volume, the usable capacity is one disk. In a three-disk X-RAID volume, the usable capacity
is two disks. In a four-disk X-RAID volume, the usable capacity is three disks.
