This table can be copied and used to plan your air conditioning requirements for your server(s). Use the
footnotes at the bottom of this page to assist in calculating the values.
See Table A-6 for an example of how to arrive at a value required for air conditioning based on the system
configuration described for Table A-6.

a. For example, if you have two bc1100 blades the calculation for this would be:
(2 x 23.6 Watts)/0.7 = 67.43 Watts.

c. The power supply thermal load is included in the value calculated for the
blades. The power supply efficiency is 0.7 so when you divide by 0.7, the
resulting value represents the thermal load of the blade plus the thermal
load in the supply due to each blade.
