I'am planning to use ESXi 6.0 U3 (my server has 3 cpu sockets). While i was checking VMware's compatibility guide i realized that the number of sockets that i can choose from the drop down menu does not include 3 sockets. Is it possible to use 3 sockets ?
Three sockets are pretty uncommon for computers. What system (vendor/model) is this?
Assuming that it's not on VMware's HCL anyway (i.e. not officially supported), you may simply give it a try, and install the Hypervisor to see whether it works.
Youre speaking about Sockets... but your screenshot displays "Cores".
You are right! I'am interesting in number of 'Sockets' but the screenshot unfortunatelly shows 'Cores'.
