The interesting thing about a new building block for networking, is learning how it can solve problems for you. An Ethernet fabric is a new building block and there is a good white paper, "Deploying Brocade VDX 6720 Data Center Switches with Brocade VCS in Enterprise Data Centers", available at this link:
The white paper has several examples of how to use the Brocade VDX Data Center Switch family of products in a wide range of use cases. What I find very interesting about the VDX is how flexible it is and the range of use cases it can be applied to.
Take a look at this white paper let me know if you have questions.
