oVirt questions

I'm reading through the documentation at
https://www.ovirt.org/documentation/, and I see 5 different ways oVirt can
be deployed.

I'm looking for a way to manage multiple physical servers from 1 interface,
and be able to deploy new VMs (or delete VMs) as necessary. I'm trying to
figure out what the difference is between an oVirt Node and the oVirt
Engine, and how the engine differs from the Manager.

oVirt Engine requirements look to be a minimum of 4GB RAM and 2CPUs.
oVirt Manager

oVirt Nodes, on the other hand, require only 2GB RAM.

I think that the Engine and "Manager" are the same thing.
Is this correct?

Additionally, I *think* that a node is just a physical server.
So if I install an oVirt Node onto a server with let's say 8GB physical
RAM, do I have to allocate 2GB of RAM to oVirt (meaning I only have 6GB RAM
available to the VMs)? How does that work?
