4.4.1 Storage Volume
A volume is a basic storage space on the NAS. To store data on the NAS, you must create at least
one volume. Your NAS supports the following:
• Internal volumes (built on the hard disks installed in the NAS)
• External volumes (built on the external storage devices attached to the NAS)
Internal Volumes
RAID Types
The following table describes RAID types.
Volume
This section shows the current storage usage for each volume built directly on top
of a RAID. These volumes have higher access performance than volumes on a disk
group but are less flexible in regards to size.
Details include the currently used percentage of the volume.
Used (Normal) - green on the circle represents the volume’s percentage of used
capacity in a healthy state.
Used (Degraded) - orange on the circle represents the volume’s percentage of
used capacity in a degraded state. Degraded means one or more disks has failed
but you can still replace a faulty disk to recover the volume.
Crashed - a red exclamation point represents the volume is in a down state.
Down means you cannot recover the volume.
Available - gray on the circle represents the volume’s percentage of unused
capacity.
This section also displays the volume’s used capacity, and total capacity available.
Volume on Disk Group This section shows the current storage usage for each volume built on top of a
disk group. You can expand a volume’s size after creation if the disk group has
unallocated space. You can also expand a disk group by adding hard disks.
