Hi!
Thank you for considering StarWind product. With StarWind you have two options:
- The scenario that you`ve mentioned, when StarWind is installed on the WS hardware boxes. If the budget is the problem here you can install StarWind on the free Hyper-V Server. Also StarWind sales guys do can be flexible when talking about price
- You can wait for the VSA of StarWind that is already available in the Beta of v8.
PM or email me if you`ll decide to go with StarWind and I`ll gladly assist you.
Obviously you do can create share storage with VMware for your vSphere infrastructure, but in my opinion it is better idea to have solution from VMware for it. Here is the pretty good article with comparing those solutions:
If you`ll still decide to go with the presenting Windows based scenario those links will be useful for you (they are pretty old but should still work for you)::

NFS in windows server 2012 to ESX 5.1 | Peter's ruminations
Each soution has it pros and cons but in my opinion it would be better to go with some VSA or other solution that`d functioned directly from the ESX hosts, thus giving you the benefit of DAS speed.
