How much they produce Heat and how can I calculate the heat per machine or product categories

Re: Heat calculation of machines

You can find out the BTU (British Thermal Units) for each server unit using the following formula.

"BTU" is used to describe the heat value (energy content) of fuels, and also to describe the power of heating and cooling systems.

BTU = Volts X Amps X 3.41

Once you have calculated the BTU for each individual server / unit, you can combine & get the correct values per categories.

Hello,

A very Handy tool. All it needs is any one value(Volts / Watt)... & u have the corresponding values in other units.

You have BTU/Hour & BTU/Minute & BTU/Sec

Re: Heat calculation of machines

Nice try, Adric and HD, but that won't work in this case--that's the amount of heat a given voltage and wattage CAN produce, but not what the actual equipment produces.

S, BTUs are a standard metric published on each product's QuickSpec. These are available from the Product Bulletin page: http://h18000.www1.hp.com/products/quickspecs/productbulletin.html

ProLiant servers also have Power Calculators to determine the exact power requirements and heat output for a specific configuration: http://h30099.www3.hp.com/configurator/powercalcs.asp

Re: Heat calculation of machines

Of course the quickspecs for the server contain the BTU information, but the general formula how BTU is calculated is the one I mentioned.

You can find it here: :)

Re: Heat calculation of machines

I may be wrong; I thought the Volts/Watts consumed were CONSTANT, hence BTU would be too.
Hence, a simple way to calculate. ;)

Re: Heat calculation of machines

Sorry, guys, your calculations will only result in calculating BTUs based on regulation-plate specs, which is not accurate. It doesn't take into account the difference between number of processors, type of processor, number of drives, amount of memory, etc.
