Virtual Disk
The Virtual Disk (VD) feature enables the expansion of the NAS capacity beyond
the physical storage of a NAS. By using iSCSI protocol, one NAS unit acts as the
master of a NAS stack and one or more additional NAS units act as stack targets to
expand the capacity of the master NAS unit. Once a Virtual Disk is created, you
can create disk shares and use them for data exchange, storage, and backup, just
like network shares created using local physical storage (internal disk drives,
eSATA disks, and USB disks).
NOTE The NAS supports a maximum of eight virtual disks. Each virtual disk drive will be
recognized as a single logical volume in the local system.
From the Disk Management > Virtual Disk window, you can add, delete, or view
the properties of a virtual disk.
• Add Virtual Disk—Click to add a virtual disk.
• Target / Vir tual Disk Name—Target server IP address or hostname,

NTFS, or HFS+.
• Total Size—Size of virtual disk, for example 100 GB.
• Free Size—Available space on the virtual disk.
