+You can create Cinder volumes as VMDKs or as First Class Disks (FCDs).
+
+An FCD, also known as an Improved Virtual Disk (IVD) or Managed Virtual Disk,
+is a named virtual disk independent of a virtual machine.
+Using FCDs for Cinder volumes eliminates the need for shadow virtual machines.
+
+The FCD backend is offered in addition to the default VMDK backend.
+If you use FCD as the backend driver for Cinder, you can use both FCD and
+VMDK volumes in the same deployment.
