VMware View 4.5 design considerations.

I am thinking about a possible VMware View 4.5 design consideration.

As some of you may know, we run a NetApp 3140, and a shelf 14 FC drives on each filer. One filer has 14 drives of Sata.

How are those of you running view now meeting your I/O Requirements? How did you build your cluster? Did you choose , blade or standard rack servers? Or maybe a scale up model?

I want to know what you are using. Please comment!
