Virtualizing ESX Hosts.

If I am not wrong , I believe there are environments where they have ESX hosts set up as Virtual on the SAN, I mean they are Physical ESX servers.

In this case I am not sure where do ESX hosts get RAM and CPU resources that in turn they will provision to Virtual Machines.



Thanks

most likely there is a physical ESXi server somewhere on the network using the SAN as a datastore.  You cannot run a virtualized hypervisor, to my knowledge.

Yes, this is what we called Nested ESXi.

The ESXi server is a virtual server, hosted on a Physical ESXi server, it's mainly used in Labs, and it's not VMware Supported, but it's possible.

I know of ESXi as virtual host in VMware workstation or VMware fusion,etc...
However in Production environments I am not aware of that.. just heard about it...
I thought if ESXi can be installed as virtual on the SAN, that might save Admins from the cumbersome wiring.

I heard about ESXi that boots from  the SAN, but the resources CPU/RAM still get provisioned from ESXi physical server...

Nested ESXi servers (e.g. Virtual) are ONLY used for Labs and Testing, NOT FOR PRODUCTION!

It's not supported, and much slower!

Any virtual machine, gets its resources from the Host.

As Andrew rightly mentioned, The Nested ESXi is only for the purpose of labs. I have an environment with nested ESXi which i use for my training.
ESXi is a bare metal Hypervisor. The fact that they let you put it on virtual machine is only for experimental purposes.
That's the reason you will not directly find ESXi on the OS list. Only after you finish creating a VM, you will be able to find it by going to edit settings>OS options.
This is what it says when you choose it.
