I guess that forces my hand. I'll have to do a FreeNAS or OpenFiler NAS and a separate ESX server. I'll probably use a GigE crossover cable between the two boxes for a dedicated SAN backbone.
I think this is definitely a better way to do things but I have a deep hatred for artificial software limitations. I know my 3WARE card works in Linux. I know SATA is reliable enough for what I'm doing here. I should be able to make it work. It's my stuff, I decide to take the "risk"
Anyway, that means I need to buy that Lian Li case now. Probably won't get to finish this project up until after my trip to Boston now.
