The Create Virtual JBOD Disk Wizard opens.
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.
For security reasons, QNAP does not recommend using the "admin" account.
The default port is 8080. If HTTPS is enabled, the default port is 443.
Enabling iSER increases data transfer speeds and reduces CPU and memory load.
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.
The size of the VJBOD disk cannot be changed after creation.
Setting |
Description |
---|---|
4K bytes sector size |
Changing the sector size to 4 KB increases LUN performance for specific applications and disk types. |
SSD cache |
The SSD cache will be used to improve VJBOD disk access performance. |
QTS starts creating a dedicated iSCSI target on the remote NAS for the VJBOD disk.
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
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 |
Description |
---|---|
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. |
QTS 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.
Action |
Description |
---|---|
Create New Storage Pool |
Creates a storage pool using the VJBOD disk |
Create New Static Volume |
Creates a static volume using the VJBOD disk |
Do nothing |
Ends the creation process. You can configure the VJBOD disk later. Tip:
To create a storage pool or static volume on a VJBOD disk later, go through the normal steps of creating a storage pool or static volume. Then on the disk selection screen, under Enclosure Unit select Virtual JBOD. |
