[Nut-upsuser] Advice on small office UPS

[Alastair Sherringham]

Hello Folks,

I have a couple of questions - one about a basic UPS choice I am to
make for a small UK office environment and the second about NUT
Windows support. For the UPS, I have 2 or 3 servers, a phone system
and a switch i.e. a basic :

- Dell R410 1U (2x IEC)
- Dell SC1425 1U (1x IEC)
- Mitel 3300 CXi phone system (1x IEC)
- Netgear GS748T switch (1x IEC)

It would be good to also be able to plug in another couple of servers
e.g. Dell PE1800 (2x IEC) and HP Proliant micro (1x IEC) but the above
is the minimum required.

Given the current status of NUT and the compatibility list, I was
looking at Eaton, and specifically the :

Eaton 5PX 2200IRT

However, before realising Eaton have a UPS selector to gauge
rating/size, I was using the APC UPS selector to check. With my
servers, switch and phone system, it was suggesting UPS systems like :

Smart-UPS 2200VA LCD
Smart-UPS XL 2200VA
Smart-UPS 3000VA LCD.

This includes adding the 2 extra servers I list above (Dell PE1800 and the HP).

The Eaton UPS selector is very similar but seems to be suggesting
quite different, larger, more expensive UPS systems like :

Eaton 9170plus 3kVA HW

Not only larger, but quite a bit more expensive.

The Eaton 5PX 2200IRT seemed to be (roughly) equivalent to the
Smart-UPS 2200VA, but without the experience or knowledge of this
area, I don't know and the different results suggested by the  tools
would concern me.

Any advice or thoughts on the above?

Lastly, one of these servers runs Windows 7 64 bit. I see NUT has a
Windows installer for version 2.6.1. I was a little surprised to see
this - but would be happy if it works on Windows as well. Does anyone
use NUT on Windows 7? It would be a "slave" to the UPS attached to a
Linux (Debian Stable) system (R410). I am not sure how to integrate
the Windows box into the NUT UPS system otherwise - native vendor
driver/tools?

Any feedback would be very welcome.

Cheers,
