How to use Virtual Disks on your QNAP NAS?

"Virtual Disk Drive (VDD) adds flexibility to storage expansion along with ease of management"


QNAP's unique "Virtual Disk Drive" adds flexibility to expand the capacity of your NAS. Using the built-in iSCSI initiator, your NAS can connect to iSCSI targets on your network and use them as virtual disks. Each virtual disk can be used as a single volume on your NAS. Up to eight virtual disks can be stacked in this way. The NAS serves as a storage stack-chaining master. The user only needs to connect to a single entry point (QNAP NAS) to reach and use all of the iSCSI target stores on the network. This demonstration will show you how to use virtual disks to expand your storage. Let's get started!

VDD Architecture

Create a virtual disk

Click "Add Virtual Disk" on the "Remote Disk" page.

Surveillance Station usage scenario

Follow the four steps below to connect to an iSCSI target on a remote server.

  • Enter the IP address of the target server (the server that has the iSCSI target on it.)
  • Click “Get Remote Disk” to get the iSCSI target list.
  • Select the iSCSI target on the remote server that you wish to connect to as a virtual disk.
  • Click “Next”.
Surveillance Station usage scenario

If this is the first time you are connecting to the virtual disk (iSCSI target), you will have to format it before it can be mounted to the NAS.

Surveillance Station usage scenario

When the formatting has finished, the status will indicate "Ready". You can now use the virtual disk.

Use Virtual Disk on Your QNAP NAS

You can now create shared folders on the virtual disk. Select the "VirtualDiskX" (where X = 1 - 8, the maximum number of virtual disks is eight) from the "Disk Volume" dropdown list when creating a new shared folder.
