Note:

Thin provisioning: This approach can over-allocate the volume capacity for each

workgroup regardless of the physical storage limit, and the physical disk space is

used only when files are written into the volume. With thin provisioning, the

volume space is fully utilized.

Thick provisioning: This approach can instantly allocate physical storage space

for the volume. Physical space will be created as soon as the space is allocated

for the volume, and that space cannot be used by other volumes.

A thick provisioned volume is usually more efficient for high frequency read/write

activities. Because the space has been allocated for the volume, the

predicament of insufficient physical space can be avoided, but the use of space

is relatively inefficient.

Removing volumes

To remove a volume, select a volume to be removed and click "Remove Volume". Click

"Apply" and the selected volume is removed.

Expanding volumes

Follow the steps below to expand the capacity of a volume.

1. Select a volume to be expanded and click "Expand Volume".

3. The capacity of the volume is expanded.

Available volume operations

Click "Actions" and choose to configure the cache settings, format a volume, check the

file system of a volume, reclaim space for a volume, or encrypt a volume.

Note:

All data on a disk will be erased if that disk is formatted. Please use the "Format"

feature with caution.

For encryption related options (Change, Download, Save, Lock this Volume),

please refer to Encryption .

For disk volumes larger than 2TB, it is recommended to format them to the EXT4

file system.

If you have a hot spare drive set up in a RAID configuration, please be sure to

manually remove that drive before expanding a RAID Volume or adding a drive to

that volume.
