If shared storage exists, UIS reserves a storage volume on the shared storage for each VM upon VM creation. For high performance, you can mount such a storage volume as a block device to a VM.
To mount a block device to a VM:
On the top navigation bar, click Storage, and then select Block Storage > Block Device Management from the navigation pane.
Click Add and create a block device.
