QuTS hero 5.0.x

Creating a VJBOD Disk from a New LUN

  1. Go to Storage & Snapshots > Storage > Storage/Snapshots.
  2. Click Create, and then select Create Virtual JBOD.

    The Create Virtual JBOD Disk Wizard opens.

  3. Click Next.
  4. Specify the IP address or hostname of the remote NAS.

    The remote NAS must have at least one storage pool containing at least 153 GB of free space.


    Click Detect to view the IP addresses of all QNAP NAS devices on the local network. Click Local Host to use the IP of the local NAS.

  5. Specify an administrator account and password of the remote NAS.

    For security reasons, QNAP does not recommend using the "admin" account.

  6. Optional: Specify the system administration port of the remote NAS.

    The default port is 8080. If HTTPS is enabled, the default port is 443.

  7. Click Test to test the connection to the remote NAS.

    If prompted, complete 2-step verification. This is required if the remote NAS has enabled 2-step verification.

  8. Click Next.
  9. Optional: Select the local interface that will be used by VJBOD.
  10. Optional: Select the remote interface that will be used by VJBOD.
  11. Optional: Enable iSER.

    Enabling iSER increases data transfer speeds and reduces CPU and memory load.

    1. Ensure that selected local and remote network adapters are iSER-compatible and have iSER listed under Supported Protocols.
    2. Select Use iSER when available.
  12. Click Next.
  13. Select Create a new iSCSI LUN on the remote NAS.

    VJBOD does not currently support encrypted LUNs.

  14. Optional: Select Host Binding.

    When selected, only the local NAS will be able to access the VJBOD disk.


    Enable this option if the VJBOD disk will be used to store sensitive information.

  15. Click Next.
  16. Select a storage pool.
  17. Click Next.
  18. Specify the capacity of the VJBOD disk.

    The size of the VJBOD disk cannot be changed after creation.

  19. Optional: Configure advanced settings.



    SSD cache

    The SSD cache will be used to improve VJBOD disk access performance.

  20. Click Next.

    QuTS hero starts creating a dedicated iSCSI target on the remote NAS for the VJBOD disk.

  21. Optional: Enable CHAP authentication.

    An initiator must authenticate with the target using the specified username and password. This provides security, as iSCSI initiators do not require a NAS username or password.

    • Username

      • Length: 1 to 127 characters

      • Valid characters: 0 to 9, a to z, A to Z, colon (:), period (.), hyphen (-)

    • Password

      • Length: 12 to 16 characters

      • Valid characters: 0 to 9, a to z, A to Z, all special characters

  22. Optional: Enable CRC checksums.

    Initiators and targets communicate over TCP connections using iSCSI protocol data units (PDU). The sending device can send a checksum with each PDU. The receiving device uses this checksum to verify the integrity of the PDU, which is useful in unreliable network environments. There are two checksum types, which can be enabled separately.

    Checksum Type


    Data Digest

    The checksum can be used to verify the data portion of the PDU.

    Header Digest

    The checksum can be used to verify the header portion of the PDU.

  23. Click Next.
  24. Review the summary, and then click Next.

    QuTS hero creates the iSCSI target and LUN on the remote NAS, and then creates a VJBOD disk using the LUN. The disk appears at Storage & Snapshots > Storage > Disks/VJBOD.

  25. Select a follow-up action.



    Create New Storage Pool

    Creates a storage pool using the VJBOD disk

    Do nothing

    Ends the creation process. You can configure the VJBOD disk later.


    To create a storage pool on a VJBOD disk later, go through the normal steps of creating a storage pool. Then on the disk selection screen, under Enclosure Unit select Virtual JBOD.

  26. Click Finish.
