Creating a Thick or Thin Multiple Volume

  1. Go to Main Menu > Storage & Snapshots > Storage/Snapshot.
  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 the volume type.
    • Thick Multiple Volume

    • Thin Multiple Volume

    For details, see Volumes.

  4. Select the storage pool that will be used to create the volume.

    You can select an existing storage pool or create a new storage pool immediately.

  5. Optional: Create a new storage pool.
    1. Click the Create Storage Pool icon .

      The Create Storage Pool Wizard opens.

    2. Click Next.
    3. Optional: If you want to use disks in a connected expansion unit, select the expansion unit from the Enclosure Unit list.

      You cannot select disks from multiple expansion units.

    4. Select one or more disks.
      Warning:

      All data on the selected disks will be deleted.

    5. Select a RAID type.

      Storage & Snapshots displays all RAID types that match the number of selected disks and automatically selects the most optimized RAID type.

      Number of disks

      Supported RAID Types

      Default RAID Type

      One

      Single

      Single

      Two

      JBOD, RAID 0, RAID 1

      RAID 1

      Three

      JBOD, RAID 0, RAID 5

      RAID 5

      Four

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

      RAID 5

      Five

      JBOD, RAID 0, RAID 5, RAID 6

      RAID 6

      Six or more

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

      Note:

      RAID 10 requires an even number of disks.

      RAID 6

      Tip:

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

      For details, see RAID Types.

    6. 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.

    7. Click Next.

      The Pool Creation Summary window opens.

    8. Click Create.

      A confirmation message appears.

      Warning:

      Clicking OK deletes all data on the selected disks.

    9. Click OK.
  6. Click Next.
  7. 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 "_"

  8. Specify the capacity of the volume.

    The volume type determines the maximum volume capacity.

    Volume Type

    Maximum Size

    Thick

    Amount of free space in the parent storage pool.

    Thin

    Twenty times the amount of free space in the parent storage pool

    Setting the maximum size of a thin volume to a value that is greater than the amount of free space in the storage pool is called over-allocation.

  9. 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.

  10. Configure advanced settings.

    Setting

    Description

    Alert threshold

    QTS issues a warning notification when the percentage of used disk space on the volume reaches the specified 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 access to data if the entire NAS is stolen.

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

    Warning:
    • Saving the encryption key on the NAS can result in unauthorized access to data if the entire NAS is stolen.

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

    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.

  11. Click Next.
  12. 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.
