Virtual Disk
The Virtual Disk (VD) is based on iSCSI technology, which makes it become the
stack master and can connect to the other stack targets. With the VD, you can
expand the capacity of your NAS and use it as the system disk volume(s). In
addition, you can create disk shares and use them for data exchange, storage and
backup, just like the local disk shares.
NOTE
This function and its content is only applicable on some NAS models.
Each virtual disk drive will be recognized as a single logical volume in the local
system.
