More Vaporware?
If I recall, they've been touting Hyper-V and KVM support Real Soon Now since 2013 (http://www.computerweekly.com/blogs/StorageBuzz/2013/10/simplivity-converged-storage-c.html). Neither exists in the wild yet - just press releases. Considering that when we evaluated their technology it was highly vCenter dependent, I can't imagine how they might decouple it to work across hypervisors.
They do talk a good game, though.
