I pushed this build to my 4 node ESXi cluster via vSphere Lifecycle Manager. The process updated three servers before I noticed the CPUs (8-core) were at 98C...The Supermicro 300-9D IPMI was CPU throttling.
I've rebuilt the cluster again using the ESXi GA 7.0 bits, then applied the ESXi 7.0b update the same issue. ...yea, I'm a slow learner. Next, I tried just BOOTING to the ESXi 7.0b bits, the same CPU over temp issues. Seems something in the ESXi 7.0b is putting the CPU (D-2100) into a loop.
So, it seems like two issues. one for Center and one for ESXi. This one needs more testing.
