Datacenter Capacity Planner power/cooling numbers
I have been tasked with computing the cooling requirements for new server rooms and have been trying to use the Datacenter Capacity Planner tool to accomplish this.
I am confused by the results for Power (wattage and cooling). I am configuring racks of 1750's, 1850's, 2650's, 2850's, and 2950's. The wattage and cooling numbers come back the same if I configure them with redundant or non-redundant power supplies. I don't see how that can be accurate.
For example: a PE2650 shows thermal watts usage of 357W and a need of 0.1 tons sensible cooling whether it is configured as a single or dual power supply unit. Is that for one or two power supplies? Also, is it possible to get the plain BTU generation instead of the sensible cooling suggestion?
Thank you

I have forwarded your concerns to the data center infrastructure team for clarification. A response is forthcoming.

All numbers are dual power-supply configurations
PE1750: 2052 BTU
PE1850: 2130 BTU
PE2650: 1415 BTU
PE2850: 2388 BTU
PE2950: 2697 BTU
Hope this helps anyone else looking for these elusive numbers!

To get BTUs, you can change to metric by clicking the "properties" button. It's going to also change to degC, kg, and cu.m/hr
