Ok so here is the trick: Go to this website follow the instructions and get a free esxi license from wmware. [URL]   Then  go to dell and get the esxi distribution with power edge modifications for you power edge model..   After all this web searching every thing worked.   Be prepared to do some manual labor, reading manuals, as the setup is not strait forward. I needed the power edge user and installation manuals to figure every thing out and be prepared to spend some quality time with IDRAC. It is well worth the effort ! Thanks Tom
I recently bought a  poweredge r720 on Amazon (and probably paid too much for it, but that will probably be another post ). It came with an eval windows 2012 OS installed and I want to upgrade it to EDSI. I downloaded the install package from the DELL web site. Will it ask for an EDSI license during the install? Has anybody previously done this. Any advice or help will be graciously accepted.  
I am a noob here, please forgive my noob question! I have downloaded ESXI for 
my Poweredge, do I need a license?
