Lots of great respnoses.
We're documenting all the things we want to be powered from an
alternate source, then finding what else needs to be up to support
that.
Once we have that information, we're going to consult a professional :-)

When I worked for a bank, their DR site was about 10 miles from the 'home
office'.
This was to close for me to feel comfortable, but they didn't want the
travel expense
for tests (1 each 6 mo) to an office they had 200 miles away. Auditors made
them
do something, so they chose a 3d place that was
I was thinking about your generator and auto-failover need.
I saw a couple of years back at Sears, and a couple of months ago if I
remember right at Rural King,
a 'backup generator' sized for a house. Probably enough to keep a small
server room (a full rack,
and a room type HVAC unit) running.
Home depot has those as well. Look on the website and you can find
25kw generators that runs on natural gas or propane. I think I remember
that one being under $8k.
Since the original poster mentioned a warehouse, I bet they already
have access to propane and possibly a nice big tank already on

UPSes and critical loads on this, including your HVAC. If the HVAC
needs are big enough, you might want
one generator for HVAC and another for everything else, depending on
running the numbers of course!
Are you sure you want your servers running if the generator for the
Another good pount. Don't just crank and run your genset. Put the full
load on it at least once a month.. We have automated tests weekly and
manual full load tests monthly.

First question - are all of these systems on existing UPS so that they
will stay running in the 1 second to 10 minutes window before the
generator cuts on? First guess about the first question - kinda sorta

The other servers, and primary switch are connected to the other 3,

Hmm, crank the generator in 12-15 minutes... does that
I have helpped build a couple of data centers and mange them afterward.
Howards advice is good about the UPSes. But also monitor the UPSes with

still good left in them) for a few. ... Dynamic

Alot of these kind of things are being discussed internally, but right
now we're attempting to just size out how big of a generator we need
to power what we want.
You are doing it backwards. See Tim Jackson's post to
My 2 cents on this topic:
If you can do this small scale (and this may not apply to your situation)
get a Kill-A-Watt and hook up each of your devices through it. It will
tell you EXACTLY how may watts/amps/etc each device is actually pulling from
the wall. You can test different devices under
