nothing new
You write this as if StorSimple is something new..obviously it is not....is there some new ability with this now Microsoft branded Storsimple vs what was available before?
In talking with a friend that has worked at Storsimple for the past two years or so he said even before MS bought them Azure was very popular with Storsimple customers (he may of mentioned Azure being the vast majority of what their customers use I don't remember that conversation was 8+ months ago). But the point was that their customer base was very much Microsoft oriented already.
