Not so fast...
Couple of things that make me think this is a lot harder for Nimble than just replacing spinning disk with flash:
1. Dedup. I don't see how how their AFA can be competitive without it.
2. CASL wasn't designed for all flash, so does this mean a complete OS rewrite?
Seems to me the basic argument they used against legacy vendors trying to do hybrid when they (Nimble) came along was, "You're trying to make legacy code do modern stuff it wasn't designed to do." Aren't they in the exact same position now that the move to all flash has happened so much faster than they thought it would?
