I am using it on my windows 7 right now... It's stable and even give high IOPS than my hp4500g2, amazing. I'm going to buy the tray, transfer the disk on my hp dl380 and see what happens.
I'm new to vsan/starwind. Unfortunately I don't have budget for the new san until next year, for sure I'm going to use starwind. So for now I would like to test starwind on one esxi, is it totally free to use the free-version?
