Set Up Storage

Storage space is added to your Virtual Machine (VM) by using storage elements in your Virtual Data Center (VDC). Storage name, availability zone, size, OS image, and boot options are configurable for each element.

Add Storage to a Server or a Cube

  1. Drag a storage element (HDD or SSD) from the Palette onto a Server or a Cube in the Workspace to connect them together. The highlighted VM will expand with a storage section.

  2. Click the Unnamed HDD Storage to highlight the storage section. You can now see new options in the Inspector on the right.

Note: You cannot change the storage type after provisioning.

Configure Storage

  1. Enter a name that is unique within your VDC.

  2. Select a zone in which you want the storage device to be maintained. When you select A (Auto), the system assigns the optimal Zone. The Availability Zone cannot be changed after provisioning.

  3. Specify the required storage capacity. The size can be increased after provisioning, even while the server is running, as long as this is supported by its operating system. It is not possible to reduce the storage size after provisioning.

You can select one of the IONOS images or snapshots, or use your own. Only images and snapshots that you have access to are available for selection. Since provisioning does not require you to specify an image, you can also create empty storage volumes.


  1. Set the root or administrator password for your server according to the guidelines. This is recommended for both operating system types

  2. Select an SSH key stored in the SSH Key Manager.

  3. Copy and paste the public part of your SSH key into this field.

  4. Select the storage volume from which the server is to boot by clicking on BOOT or Make Boot Device.

Alternative Mode

  • When adding a storage element using the Inspector, select the appropriate check box in the Add Storage dialog box. If you wish to boot from the network, set this on the server: Server in the Workspace > Inspector > Storage.

  • It is recommended to always use VirtIO to benefit from the full performance of InfiniBand. IDE is intended for troubleshooting if, for instance, the operating system has no VirtIO drivers installed. In this case, Windows usually displays a "blue screen" when booting.

  • After provisioning, the Live Vertical Scaling properties of the selected image are displayed. You can make changes to these properties later, which will require a reboot. You can set the properties of your uploaded images before you apply them to storage volumes in the Image Manager.

  • (Optional) Add and configure further storage elements.

  • (Optional) Make further changes to your data center.

  • Provision your changes.

Result: The storage device is now provisioned and configured according to your settings.

Add a CD-ROM drive

To assign an image and specify a boot device, you need to add and configure a storage element.

  • Click on CD-ROM to add a CD-ROM drive so that you can use ISO images to install and configure an operating system from scratch.

  • Set up a network by connecting the server to other elements, such as an internet access element or other servers through their NICs.

  • Provision your changes.

Result: The server is available according to your settings.

Delete Storage

When you no longer need snapshots or images, you should remove them from your cloud infrastructure to avoid unnecessary costs. For backup purposes, you can create a snapshot before deleting it.


  • If you delete a server and its storage devices, or the entire data center, their backups are not deleted automatically. The corresponding backups are deleted when you delete a backup unit.

  • If you no longer need the backups of deleted VMs, you should delete them manually from the Backup Unit Manager to avoid unnecessary costs.

  1. In the Workspace, select the storage device you wish to delete.

  2. Open the context menu of the element and select Delete.

  3. (Optional) Select the element and press the DEL key.

  4. Provision your changes.

Result: The storage device is deleted and will no longer be available.
