X-RAID2
X-RAID2 is the NETGEAR auto-expandable RAID technology that
TM
allows you to expand your ReadyNAS capacity by adding additional
disks, or replacing existing disks with higher capacity disks.
With X-RAID2, you do not need to know intricate details about RAID, except that as you need
more space, your volume can grow without the need to reformat your drives or move your
data to another location. Because the expansion happens online, you can continue to use the
ReadyNAS while the underlying volume capacity increases.
In addition, if your six-bay or larger ReadyNAS unit is in X-RAID2 mode, you can configure it
to use added disks to expand storage space or to increase data protection.
To expand storage space when adding drives, in the Next added drive section, select the
Will be used to expand volume radio button. To increase data protection when adding
drives, select the Will be used to add dual redundancy radio button.
Note: The Next added drive section does not display for ReadyNAS units
with fewer than six drive bays.
Adding a Second Disk for Redundancy
With only one disk in your ReadyNAS, the X-RAID2 volume has no redundancy, and provides
no protection from disk failure. However, if and when you feel the need for redundancy, add a
new disk with at least the same the capacity as the first disk. You can elect to power off the
ReadyNAS and add the disk, or you can hot-swap the disk while the ReadyNAS is online.
