If you had to rack 100 x Dell PE 2950 2x Quad Core 2.33GHz boxes. How many of what type of power circuits would you ask the colocation provider to quote?

The specs on Dells site don't indicate the max Amp draw but @ 220v it looks like they'll draw around 3 amps each. Your looking at 300 amps if they can provide you with 220v circuits.
You may want to get the max amp draw from Dell if you can for a more accurate picture.

Every 1950, or 2950 has used between 1.5 to 2.5A depending on load at 110v.
If you assume the high end of 2.5A, multiply that by 100 then you have 250A. That's going to require you to get at least 312.5A to comply with the 80% draw rule. No one I know sells 12.5A circuits, so I would assume you would need a 20 for that, for a total of 320A.
I didn't check, but are those low voltage Xeons? If they are, they will use about 1 to 1.5A.

To add, we have something here at the office called a Kill-A-Watt, its a power draw meter that plugs directly into the wall which you can use to accurately determine power usage.

Have you used the dell power calculator at www.dell.com/calc
Also you will need to adjust your power calculation depending on the memory .

Thanks for your help guys... Got what I needed.

I wonder if they have those for the bigger twist-lock applications.

Like that?

Well, was thinking a little more of a permanant fixture... but I had forgotten about those which would work for quick checks.

With 220V calculate about 1.25A - 1.5A per server. Also, deppends on HDs and RAM.
A safer value would be 1.75A.
Also deppends if you are going to keep these boxes in a high load.
