How to calculate BTU and Power Consumption for a server or array?

Thanks Geoff.  I tried that but it doesn't have all my server models listed.  Also, I don't see where it lists power consumption or BTU's for each server.  Could you tell me where?  I must be missing it.

Between the old DCCP and the ESSA, I was able to locate most of the information. I had to convert watts to btu's though on the old DCCP tool manually, using this link: http://www.rapidtables.com/convert/power/Watt_to_BTU.htm

I'm looking for the BTU and power consumption numbers for data center planning for the following models:

PowerEdge R520  159w  542.5 btu/h

PowerEdge 2950  306w  1044.11

PowerEdge 1750  346w  1180.60

PowerEdge 1850  440w  1501.34

Then for the following storage devices

PS6100xv  700w  2388.49

MD1000   430w  1467.22

PowerVault 220s  940w  3207.41

You are a lifesaver Geoff, power is definitely not my thing and you saved me.  Doing a lot of google'ing provided a lot of wrong answers it appears based on your responses too.  For instance, I found something online that said for a PE2950, it was 750W and 2697 BTU/H.  Looks like the true values are less than half of that!

Here is what a solution for a Poweredge R720 and a 4220 rack looks like:

Which servers do you have? 

Regards,

I also tried another dell server/data center planner online, which had the older server models, but that didn't list the info or have all my servers in it either.

Use a kilowatt meter like this to find  kilowatt hours used over time ( 1 hour or 24 hours ); this method is pretty accurate as many devices have options which are different from base device.( eg number of drives)...

Then use this kilowatt hour to BTU conversion link....

Looks like a pretty nifty device there, thanks.

Geoff, all my servers have redundant power supplies would that changed those numbers at all?

The R720 was configured with 2 PSU's, so those numbers would be correct.   On most servers, the second PSU is idling, so its using minimal power till its kicked over.   Your numbers shouldn't be far off.

Regards,

That's what I was thinking too, thanks for confirming.

Geoff I was talking to Dell Tech support about the same as I was trying to see BTU values for R2950, R620,R610,R720,R710

I've R620 with dual power supplies each 495W and as per tech guide it shows BTU value to be 1908 

Now when I spoke to 2 Dell tech guys they both said  to double the values as I'm using redundant power supplies & the values mentioned are for per PSU.

Now your post makes sense as I was thinking on the same lines but Dell tech differed on that, as he says at any time the heat is dissipating from both the PSU's.

I'm confused now.

Here is a Dell white paper on the subject that may shed some additional light for you:
