Only SCSI controller types are supported.

The disk size counts against the organization virtual datacenter quota.

If the class of storage is not specified, the organization virtual datacenter default is used.

If you delete a virtual machine, the independent disk first gets detached from the virtual machine.

When exporting a virtual machine with an independent disk, the disk is not tagged in any way to identify that its source was an independent disk.

The following operations cannot be performed if the virtual machine currently has an attached independent disk:

Clone vApp.

Copy vApp VM.

Capture vApp to Catalog.

Move VM.

Change owner.

When using the elastic virtual datacenter feature and allowing a provider virtual datacenter to span multiple clusters, it may be necessary to move an independent disk to a different datastore if it is necessary to attach it to a virtual machine in a different cluster. This move can be avoided by using the locality argument to create a disk in the same cluster as the virtual machine to which it will be attached (not necessarily on the same datastore).

Performance and Scalability – The scalability maximum for this feature is one independent disk per virtual machine up to vCloud Director 5.1 maximum number of virtual machines.
