I'm not a CEPH exert, but that is my understanding of it at a high level.

I would assume CEPH takes the physical disks from each host and combines them
into one logical storage for use by the entire cluster?

CEPH kind of fills the void where you don't need a dedicated, shared storage
box.

If you're going to have multiple physical VM hosts then fast shared storage is
very helpful. When you want to reboot a physical machine for OS upgrade and the
VM's are on shared storage then you can migrate them off that box in a few
seconds. Do your maintenance, reboot, migrate VM's back. No downtime.

Thanks guys. Proxmox didn't even come up in my searches. I'll look into it. If
anyone really knows the space and wouldn't mind spending 15 minutes discussing
what we need I would appreciate it.

VMs are a great way to go depending on the job(s) you need to do. As it happens
a lot of jobs (e.g. DNS) are not particularly compute intensive, so it's a
great way to stretch resources. We find we can run 3 or 4 virtual machines on
each physical machine.
We used VMware from the get-go, but did not get many of the paid-for bells and
whistles. VMware can become pretty expensive, where other solutions (e.g.
Proxmox) has an advantage because of open source.
The other consideration is containers, which can be thought of as VM-lite.
Containers provide almost all of the advantages of VMs with a significantly
lighter load on the hardware. As a result, you can load up more applications on
less hardware. The leading contender in the container space is Kubernetes and
it's also open source.
Pick your poison with someone you know who can go over your requirements.

I want something that will at least do some monitoring of VM's, backups,
snapshots, etc. Managed upgrading would be great but not as big a priority for
me (at least I don't think so).
Since I don't know what I don't know, I am asking the experienced crowd.
It seems the two real choices are VMWare and Zen. Are there others? Commercial
support seems nice, is it worth paying for? What I will run is important for
sure.
I spent a few hours last night and I more confused now than when I started.
