5. vCloud Resource Design : 5.10 Storage Independent of Virtual Machines
   
5.10 Storage Independent of Virtual Machines
The use of independent disks with vCloud Director 5.1 allows updates of virtual machines without impacting the underlying data. For example, we can detach the data disk from the existing virtual machine, delete the existing virtual machine, recreate this virtual machine, and reattach the original disk. This feature is a key enabler to enhance the deployment of a Cloud Foundry PaaS cloud within a vCloud environment.
