Creating a Static Volume
To create a SED secure static volume, see Creating a SED Secure Static Volume.
- Go to Storage & Snapshots > Storage > Storage/Snapshots.
-
Perform one of the following
actions.
NAS State
Action
No volumes or storage pools
Click New Volume.
One or more volumes or storage pools
Click Create > New Volume.
The Volume Creation Wizard window opens.
-
Select Static Volume.
Tip:
-
Click Detailed Comparison to view featural differences between the volume types in a new window. You can select a different volume type to see the corresponding description and graph, and also apply a new selection.
-
To create a thick or thin volume, see Creating a Thick or Thin Volume.
-
- Click Next.
- Optional:
Select an expansion unit from
the Enclosure
Unit list.
Important:
-
You cannot select disks from multiple expansion units.
-
If the expansion unit is disconnected from the NAS, the storage pool becomes inaccessible until it is reconnected.
-
-
Select one or more disks.
Important:
-
For data safety, you cannot select disks that have the status Warning.
-
The status In Use means that a disk is currently formatted as an external disk, and may contain current user data.
-
If you select a disk with the status In Use, QTS will temporarily stop all disk storage services on the NAS in order to unmount the disk, and then delete all data and partitions on the disk.
Warning:All data on the selected disks will be deleted.
-
-
Select a RAID type.
QTS displays all available RAID types and automatically selects the most optimized RAID type.

RAID 6
Tip:Use the default RAID type if you are unsure of which option to choose.
For details, see RAID Types.
- Optional:
Select the disk that will be
used as a hot spare for this RAID group.
The designated hot spare automatically replaces any disk in the RAID group that fails.
For details, see RAID Disk Failure Protection.
- Optional:
Select the number of RAID 50 or
RAID 60 subgroups.
The selected disks are divided evenly into the specified number of RAID 5 or 6 groups.
-
A higher number of subgroups results in faster RAID rebuilding, increased disk failure tolerance, and better performance if all the disks are SSDs.
-
A lower number of subgroups results in more storage capacity, and better performance if all the disks are HDDs.
Warning:If a RAID group is divided unevenly, the excess space becomes unavailable. For example, 10 disks divided into 3 subgroups of 3 disks, 3 disks, and 4 disks will provide only 9 disks of storage capacity.
-
- Click Next.
- Optional:
Specify an alias for the
volume.
The alias must consist of 1 to 64 characters from any of the following groups:
-
Letters: A to Z, a to z
-
Numbers: 0 to 9
-
Special characters: Hyphen (-), underscore (_)
-
- Optional:
Encrypt the volume.
QTS encrypts all data on the volume with 256-bit AES encryption.
-
Specify an encryption password.
The password must contain 8 to 32 characters, with any combination of letters, numbers, and special characters. Spaces are not allowed.
Warning:If you forget the encryption password, all data will become inaccessible.
- Verify the encryption password.
- Optional:
Select Save encryption key.
This setting saves a local copy of the encryption key on the NAS. This enables QTS to automatically unlock and mount the encrypted volume when the NAS starts up. If the encryption key is not saved, you must specify the encryption password each time the NAS restarts.
Warning:Saving the encryption key on the NAS can result in unauthorized data access if unauthorized personnel are able to physically access the NAS.
-
Specify an encryption password.
- Optional:
Configure SSD
over-provisioning.
Over-provisioning reserves a percentage of SSD storage space on each disk in the RAID group to improve write performance and extend the disk's lifespan. You can decrease the amount of space reserved for over-provisioning after QTS has created the RAID group.
Tip:To determine the optimal amount of over-provisioning for your SSDs, download and run SSD Profiling Tool from App Center.
- Optional:
Configure advanced
settings.
Setting
Description
User Actions
Alert threshold
QTS issues a warning notification when the percentage of used volume space is equal to or above the specified threshold.
Specify a value.
Accelerate performance with SSD cache
QTS adds data from this volume to the SSD cache to improve read or write performance.
-
Create a shared folder on the volume
QTS automatically creates the shared folder when the volume is ready. Only the user account that creates the shared folder will have read/write access to the folder.
Note:This setting is only available when logged in as "admin".
-
Specify a folder name.
-
Select Create this folder as a snapshot shared folder.
A snapshot shared folder enables faster snapshot creation and restoration.
Bytes per inode
The number of bytes per inode determines the maximum volume size and the number of files and folders that the volume can store. Increasing the number of bytes per inode results in a larger maximum volume size, but a lower maximum number of files and folders.
Select a value.
-
- Click Next.
-
Click Finish.
A confirmation message appears.
Warning:Clicking OK deletes all data on the selected disks.
QTS creates and initializes the volume, and then creates the optional shared folder.
