HPE/Simplivity not a competitor
HPE made a huge mistake (not their first!) in acquiring Simplivity; fortunately for them, it cost less than a billion dollars.
Simplivity's single point of failure h/w as well as their single admin username/password (all customers share the same admin password and it is unchangeable; this is why you must contact Simplivity Support to upgrade your system - you can't have the password) are hurdles too great for them to overcome. Add-on to the fact that they cannot support more than 6-8 nodes in a cluster and you can see this is a small-business competitor only. Also, I think they still only support ESXi.
All I'm saying is no service provider would ever use Simplivity: Too small an architecture, too much effort to upgrade, and too insecure. Furthermore, no govt institution is allowed to use it due to the inherent shortcomings in the architecture since all customers have the same admin password. This is an absolute security nightmare!
I have no idea why HPE would want to buy Simplivity, but they did. Better to not be in the market at all than to be known as the worst of the bunch.
