5.2.1 Background
VMware has introduced storage clusters and VM Storage Profiles in previous versions of vSphere, but vCloud Director has never been able to consume them.
Starting with vCloud Director 5.1 you can now expose VM Storage Profiles inside vCloud Director virtual datacenters thus allowing the end user to choose from multiple tiers of storage within the same virtual datacenter.
Figure 34 outlines the high level architecture of how vCloud Director can map these features available in the core platform.
