Adding a remote disk
- Go to Storage & Snapshots > Storage > Remote Disk.
- Click Add Virtual Disk.
- Specify the IP address or hostname of the remote server.
- Optional: Specify the iSCSI port of the remote server.
-
Click Get Remote Disk.
QuTS hero connects to the remote server and then lists all available iSCSI targets.
- Select an iSCSI target.
- Optional:
Specify a CHAP username and password.
This is required if the remote server has CHAP authentication enabled.
- 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
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.
- Click Next.
- Optional:
Specify a disk name.
The name must consist of 1 to 50 characters from the following groups:
-
Letters: a to z, A to Z
-
Numbers: 0-9
-
Special characters: space ( ), hyphen (-), underscore (_), period (.)
The following are not allowed:
-
The last character is a space
-
The name starts with "_sn_"
-
- Select a LUN.
- Optional:
Format the disk.
Select one of the following options.
File System
Compatible Operating Systems and Devices
ext4
Linux, NAS devices
ext3
Linux, NAS devices
FAT32
Windows, macOS, NAS devices, most cameras, mobile phones, video game consoles, tablets
Important:The maximum file size is 4 GB.
NTFS
Windows
HFS+
macOS
Note:The block size of the remote disks is set to 64 k during formatting.
Warning:All data on the LUN will be deleted.
-
Configure synchronous I/O.
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.
- Click Next.
- Click Finish.
QuTS hero adds the remote disk and shares it at Control Panel > Privilege > Shared Folders. By default only the admin account has access.
