less than talented people). We've never gone "down" though because of the UPS's. We were running 2 machines per RS 100; I checked the
calculator at APC (thanks for that info) and it looks like I can safely run 3, which would mean not only cost savings on adding UPS's (we can
reuse some of the existing ones) but also less heat generated (by cutting the number of UPSs in the room.
I do see some larger UPS units around $500-800 that would accommodate 8 servers through the APC PowerStrip; that may be the best option.
I'm going to test 4 machines on a UPS when they come in and are not in a live environment. If all goes we'll, I'll probably put a managed
powerswitch between it and the 4 machines (yes, wasting four outlets per strip) but cheaper than any other solution I've seen and allows us
to reuse the equipment we already have in place.
As far as KVM/IP, it's hard to justify another $8k when the computer room is 40 feet away and no one remote needs access. We're probably
going to reuse some older Cybex (remember those) we picked up about 6 months back as part of a tech lot. Then we'll rely on Terminal services
via VPN for remote access and the powerstrip for reboots. Heck, I even wrote a script once for a Kyocera cellphone to reboot them remotely. Another story....
Thanks to all

If you already have a KVM Solution you can add this box http://www.realvnc.com/products/KVM-via-IP/.
It will mean you don't throw away your current investment.

I have run as many as 10 1U servers off of a single APC 1400, which works at 15 amps, and as many 24 off a single 20amp breaker split across 2 1400VA UPSs. A 2200VA unit only needs a 20 amp circuit. What are you currently running them from? A single circuit breaker I bet, so all you really need is runtime, not power. Buy a unit that matches the power rating of your current breaker, that has extended life battery add-ons, most brands have them.
