JBOD
Two or more disks can be combined into one larger volume. Files are
sequentially saved on physical disks. The overall capacity of the
linear disk is the sum of the capacity of all disks. This configuration
does not provide disk failure protection; failure of one drive will cause
the entire array to be lost. A JBOD group is generally used for storing
a large amount of data. It is not appropriate for storing sensitive
data.

The alert threshold is used to remind users when the capacity of a chosen storage pool
is used up to the specified threshold level. A warning message will pop up when the
specified threshold level is reached. To set an alert threshold, select a storage pool,
click "Set Threshold", enter the threshold level, and click "Apply". The alert threshold is
set.

Users can expand a RAID group, add hard drive(s) to a RAID group, migrate a RAID
group, configure a spare drive, enable a bitmap and recover a RAID group for a chosen
storage pool, while the data contained in the RAID group remains intact.
Expanding storage pool capacity
With this function, RAID group capacity can be expanded by replacing hard disk drives
in an array one by one. This option is supported for the following RAID types: RAID 1,
RAID 5, RAID 6 and RAID 10. Follow the steps below to expand a RAID group:
1. Select a RAID group and click "Manage" > "Expand Capacity".
2. Select at least one hard disk drive. After the description displays "Please remove
this drive", remove the hard disk drive from the NAS or expansion enclosure.
3. After the description displays "You can replace this drive", plug in the new hard disk
drive to the drive slot. Repeat the same process for all hard drives to be replaced.
Click "Expand Capacity" to continue.
4. Click "Yes".
5. The chosen RAID group is expanded.
