QNAP QTS 4.5 Series User Manual

Remote Disk
Remote disk enables QTS to act as an iSCSI initiator, allowing you to expand NAS storage by adding iSCSI
LUNs from other NAS or storage servers as remote disks. When connected, remote disks are automatically
shared on the Shared Folders screen. If a remote disk is disconnected, the disk will become inaccessible
and QTS will try to reconnect to the target after 2 minutes. If the target cannot be reached, the status of the
remote disk will change to Disconnected.
This feature is only available on NAS models that support iSCSI.
Remote Disk Limitations

Maximum number of remote disks per NAS 8
Supported file systems ext3, ext4, FAT32, NTFS, HFS+
