FAQ - Storage
Can external storage systems (e.g. SDS@hd) be used?
Yes, external storage systems can easily be integrated via a network connection. Please be aware that security groups / rules must be configured accordingly.
Can the block storage volumes also be used without an instance or outside of heiCLOUD?
No, the volumes are bound to the platform and must be attached to an instance to be used.
Can volumes also be downloaded (e.g. for backup purposes) ?
Yes, but only via the CLI. The volume must not be attached to any instance and must first be uploaded as an image. The commands for this are:
openstack image create --volume
glance image-download --file
Can a root volume be extended to more than 30 GB?
The ephemeral root storage can not be extended. In order to get a root volume with more than 30 GB a persistent volume must be created and mounted as a root drive. When using the public Windows Server 2016 image such a volume with at least 65 GB is necessary.
Can volumes be shut down so that they do not produce any costs?
No, unfortunately this is not possible. Unlike VMs persistent volumes cause costs as long as they exist.
