I have limited IT budget and just a single ESXi host to license. But this host has 4 CPUs (18 cores per CPU). Looks like Essentials will only let 2 of the CPUs operate, so can I apply 2 Essentials licenses to get all 4 CPUs running? Otherwise, it seems that my options are to disable 2 of the CPUs, or 2 buy 4 Standard licenses + vCenter license (so about $5K vs. $700). Wisdom appreciated!
