QTS connects to the remote server and then lists all available iSCSI targets.
This is required if the remote server has CHAP authentication enabled.
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. |
The name must consist of 1 to 50 characters from the following groups:

All data on the LUN will be deleted.
If the remote server is using ZFS, select the ZFS Intent Log I/O mode for the LUN to improve data consistency or performance.
Mode |
Description |
---|---|
Synchronous |
All I/O transactions are treated as synchronous and are always written and flushed to a non-volatile storage (such as a SSD or HDD). This option gives the best data consistency, but might have a small impact on performance. |
Asynchronous |
All I/O transactions are treated as asynchronous. This option gives the highest performance, but has a higher risk of data loss in the event of a power outage. Ensure that a UPS (uninterrupted power supply) is installed when using this option. |
QTS adds the remote disk and shares it at Control Panel > Privilege > Shared Folders. By default only the admin account has access.
