I have installed ESXi 6.5 then downgraded to 6.0 U2, as either install post install are not showing the number of processors that I was expecting. The host is a HP DL385G7 with dual AMD opteron 6176. I would be expecting 24 Logical Processor (2 sockets; 12 cores), but I am only getting 8 processors,( 2 sockets; 4 cores).
Does ESXi have a processor limit? I have checked the BIOS on the server and those setting all appear correct.
