Certainly was user error
And that was to go with HPE in the first place. I haven't used any of their 3PAR hardware but if it's anything like their first generation of blade computers which I have first hand working knowledge of then I wouldn't want to touch their hardware.
The only good thing I ever had to say about those blades was that if you ever needed to warm up and you were in the data centre then you could stand behind those. We had to put in special cooling to handle the heat coming off of them. And the shutting down of the whole rack to change a power supply was just nuts.
