I am getting ready to install a new Lenovo server that I purchased with vSphere Essentials Kit. I am aware it is limited to three physical servers. I have four physical boxes in total. Can the vCenter Server Essentials manage more than three ESXi servers if two vSphere Essentials kits are purchased? Thank you.
If you have vSphere Essentials kit, it contains 6 CPU licenses of vSphere Essentials (for 3 servers with up to 2 processors each) and 1 license for vCenter Server Essentials.
So you can have 4 servers but 1 of them should be managed by second vCenter.
I'm not 100% sure. SO maybe someone else will confirm that.
I've found this:
It should give you an answer
You can‘t have more than 3 hosts in an vCenter Essentials, and you will break the EULA if you add ESXi with Essentials or Essentials Plus permanentely to an vCenter Standard (you will get a license warning). So you have to add a second vCenter to manage the fourth host.
