Liquid cooling 1MW DC Calculations

1MW_calcs.txt
Servers
2.52A * 12V = 30.24W
30.24W * 8 = 241.92W
30 servers * 241.92W = 7257.6W
30 servers * 241.92W * 0.8 = 5806.08W
30 servers * 241.92W * 0.2 = 1451.52W
7257.6W - 750W = 6507.6W
1451.52W - 750W = 701.52W
12V * 0.12A = 1.44W
1.44W * 8 = 11.52W
Power Reduction benefit
(241.92W / 1200W) * 100 = 20.16%
1MW * 1000kW/MW * 0.2016 = 201.6kW
1MW * 1000kW/MW * 0.7094 = 798.4kW [IT Compute]
201.6kW + 300kW = 501.6kW [Air movement]
1MW * 1000kW/MW / 1.200kW/Server = 833.33 Servers
1200W - 241.92W = 958.08W
1200W - 241.92W + 11.52W = 969.6W [Liquid cooled server power]
652W / 15 = 43.46W
11.52W + 43.46W = 54.98W
969.6W + 43.6W = 1013.06W [Liquid cooled server power + CDU burden]
(11.52W + 43.46W) / 969.6W * 100 = 5.670% [Fan overhead for liquid cooled server + HRU]
1000kW / 1.01306kW/Server = 987 servers
200kW / 1000kW * 100 = 20% [Facility power reduction]
1MW * 1000kW/MW - (833 servers * 1013.6W/1000) = 155.67kW [Critical IT power reduction]
200kW + 155.67kW = 355.67kW [Total energy savings converting to liquid cooling]
155.67kW / 1.01306kW/Server = 153 additional servers
153 / 833 * 100 = 18.36% server capacity increase
