I have found that HPE OneView is well suited for all of our scenarios in our shared data center platform to control all the compute hardware with firmware, patches and profiles of all compute components.
Managing the 3Pard Oneview will allow you to do things like reuse LUN IDs and setup multiple export groups with the same volume. This can cause performance issues, or worse. They could do a better job of protecting you from yourself...
Support and training when we implemented OneView were excellent. We haven't required any additional support since we put it in and configured it for our systems. The OneView systems have been stable through updates and HPE documentation is excellent.
