Chapter 8 Storage Manager Table 6 Storage Manager > Overview (continued) LABEL Volume (for Internal Volumes) DESCRIPTION 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. Shared Folder (Normal) - green on the circle represents the volume's percentage of used capacity in a healthy state. LUN (Normal) - blue on the circle represents the iSCSI LUN's percentage of used capacity. 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/Full - a red exclamation point represents the volume is in a down state. Down means you cannot recover the volume. Full means the volume has run out of space. Available - gray on the circle represents the volume's percentage of unused capacity. Volume (for External Volumes) This section also displays the volume's used capacity, and total capacity available. Details include the currently used percentage of the volume. Used - green on the circle represents the volume's percentage of used capacity in a healthy state. Full - a red exclamation point represents the volume has run out of space. Unformatted - purple on the circle represents the connected USB storage device is not formatted with a file system. Unsupported - violet on the circle represents the connected USB storage device uses a file system the NAS does not support. Available - gray on the circle represents the volume's percentage of unused capacity. Volume on Disk Group This section also displays the volume's used capacity, and total capacity available. 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. 8.3 Internal Storage 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) Cloud Storage User's Guide 49
