Creating a Single Static Volume

  1. Go to Main Menu > Storage & Snapshots > Storage > Storage/Snapshots.
  2. 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.

  3. Select Static Volume.
  4. Click Next.
  5. 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 will become inaccessible until it is reconnected.

  6. Select one or more disks.
  7. Select a RAID type.

    QTS displays all available RAID types and automatically selects the most optimized RAID type.

    JBOD, RAID 0, RAID 5, RAID 6, RAID 10

    Important:

    RAID 10 requires an even number of disks.

    RAID 6

    Six or more

    JBOD, RAID 0, RAID 5, RAID 6, RAID 10, RAID 50

    RAID 6

    Eight or more

    JBOD, RAID 0, RAID 5, RAID 6, RAID 10, RAID 50, RAID 60

    RAID 6

    Tip:

    Use the default RAID type if you are unfamiliar with the technology.

    For details, see RAID Types.

  8. 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 Spare Disks.

  9. Optional: Select the number of RAID 50 or RAID 60 sub-groups.

    The selected disks are divided evenly into the specified number of RAID 5 or 6 groups.

    • A higher number of sub-groups results in faster RAID rebuilding, increased disk failure tolerance, and better performance if all the disks are SSDs.

    • A lower number of sub-groups 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 sub-groups of 3 disks, 3 disks, and 4 disks will provide only 9 disks of storage capacity.

  10. Click Next.
  11. 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 "-" and underscore "_"

  12. 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 the SSD Profiling Tool app from App Center.

  13. Specify the number of 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.

  14. 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.

    Encryption

    QTS encrypts all data on the volume with 256-bit AES encryption.

    • Specify an encryption password containing 8 to 32 characters, with any combination of letters, numbers and special characters. Spaces are not allowed.

    • Select Save encryption key to save 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.

    • If you forget the encryption password, the volume will become inaccessible and all data will be lost.

    Accelerate performance with SSD cache

    QTS adds data from this volume to the SSD cache to improve read or write performance.

    No actions

    Create a shared folder on the volume

    QTS automatically creates the shared folder when the volume is ready. Only the NAS admin account can access the new folder.

    • Specify a folder name.

    • Select Create this folder as a snapshot shared folder.

    A snapshot shared folder enables faster snapshot creation and restoration.

  15. Click Next.
  16. 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.
