The UPS and power do come into play but at 200 watts (one server in question) is a small piece of the pie
Size of the pie can be misleading. Absolute cost is what would matter in this instance.

200w 24/7 @ $0.12 KWh is $211/annually
This server is using 4% of the UPS, if I take that as one time that is $200 worth of UPS.

Why does 200w seem so low?

That feels very low. You've got dual procs I assume, that's normally over 200W alone. Then the PSU and UPS overhead. The power of the SSDs, memory, fans, etc. It adds up. Can't imagine getting in under 300-400W.

Currently he has 2 or no drives in the server, but that will change when he adds the SSDs. So I suppose it's possible with a single Proc and no drives.

But a single proc and no drives isn't what he'd be running

And 128GB of RAM alone draws a bit.

With the assumption of 100% to the psu (450 watts) we are at just shy of $500 year for power which is noteworthy

Maybe you go single PSU when you are looking at two servers.
If you go to a single server, I'd double it up if possible.

Redundant PSU, but it would be foolish (and not sure if even possible) to exceed the limit of one supply

Absolutely, but the second one draws power when not in use. Not a ton, but some.

My power consumption comes from both looking the my apc pdus and using a kill a watt meter before sizing the UPS.
I've noticed mine automatically load balances on the PSU at about 50%

- Being 24/7 means I can't drop the whole thing for maintenance.
How much maintenance do you do? What is the annual downtime caused by VMware? Only VMware and hardware maintenance is assisted by having the second server.
Assuming a non DFRS file server, that would be assisted by this as well.
@donaldlandru , you said you have 7 servers. can't you install a DC on one of those? Are any of those virtualized or are they all bare metal?
2 servers are client owned hardware we have zero control over. I believe these are KVM.
2 more are the servers on topic here
Finally 3 servers are the "development" silo. With resource reservations I could put a domain controller and possibly a couple other services as well. Every resource used here detracts from revenue that can be generated from box, not that the business is keeping track but I am.
So yes I could use this for limited services

One of the drives I am looking at has information I think are not correct. https://www.sandisk.com/home/ssd/extreme-pro-ssd claims .15watts while active. The Samsung data center model is the other one which claims 3.4watts while active. Assuming the 3.4 that is 28 watts per server added

SSDs save a TON on power over Winchester drives. That's for sure.

I agree there. I'd have to look it up but willing to bet taking out the two 15k, adding the ssd will still be a net power savings
