Creating a SED Secure Storage Pool

  1. Go to Storage & Snapshots > Storage > Storage/Snapshots.
  2. Perform one of the following actions.

    NAS State

    Action

    No storage pools

    Click New Storage Pool.

    One or more storage pools

    Click Create, and then select New Storage Pool.

    The Create Storage Pool Wizard window opens.

  3. Click Next.
  4. 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.

  5. Select Create SED secure storage pool.

    The list of disks only displays SED disks.

  6. Select one or more disks.
    Warning:

    All data on the selected disks will be deleted.

  7. Select a RAID type.

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

    Tip:

    Use the default RAID type if you are unsure of which option to choose.

    For details, see RAID Types.

  8. 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.

  9. Click Next.
  10. Optional: Configure storage pool over-provisioning.

    Storage pool over-provisioning reserves the specified percentage of space in the storage pool in order to maintain consistent pool access performance. Storage pool over-provisioning also extends the lifespan of SSDs in the pool.

  11. Optional: Configure the alert threshold.

    QuTS hero issues a warning notification when the percentage of used pool space is equal to or above the specified threshold.

  12. Specify the encryption password.

    The encryption password must consist of 8 to 32 characters from any of the following groups:

    • Letters: A to Z, a to z

    • Numbers: 0 to 9

    • Special characters: Any except for space ( )

    Warning:

    Remember this password. If you forget the password, the pool will become inaccessible and all data will be unrecoverable.

  13. Optional: Select Auto unlock on startup.

    This setting enables QuTS hero to automatically unlock and mount the SED pool whenever the NAS starts, without requiring the user to enter the encryption password.

    Warning:

    Enabling this setting can result in unauthorized data access if unauthorized personnel are able to physically access the NAS.

  14. Click Next.
  15. Click Create.

    A confirmation message appears.

  16. Click OK.

QuTS hero creates the storage pool and then displays the information on the Storage/Snapshots screen.
