Same issue with a Supermicro board X11SDV-8C-TP8F
Spent a lot of time debugging this to come to the same conclusion.
Update 16324942 messed something up.
Strangely, 90% of the time when the system starts to boot and the sensor on my Supermicro goes red, I just unplug the PSU for several seconds, plug it back and with a bit of luck, ESXi will load just fine.
Opened a ticket with Supermicro also.
later edit:
Got a reply from Supermicro pointing out that that my system has not been tested with any 7.0 release and that they cannot help.
Which is true: VMware Compatibility Guide - System Search
Then again, it has been tested with 6.7 U3 VMware Compatibility Guide - System Search
Even later edit:
just realized SYS-E300-9D-8CN8TP is using the same motherboard as my SYS-5019D-FN8TP
If SYS-E300-9D-8CN8TP has been tested with 7.0 I wonder why my SYS-5019D-FN8TP is not listed as tested.
What are they testing? The server case? /s
