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 have decided I needed to get on the VM train.
I know, I am only 15 years behind. Honestly,
till now I haven't had a compelling reason.
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.
