The only thing I hate On a host is the Percs I wish Dell would alert or
something to notify of a failing drive.

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.
