In our data center facility at HostMDS we calculate rack space at 18 sq/ft per rack.. Thus, a 20kW rack means that we would need to deliver upwards of 1100 watts/sf !! Wow! I don't know of any data centers out there that design facilities in that range. Our latest facilities have capacity for 350 watt/sf, and even that is on the high end from what we have seen. I think a big misconception comes down to what the odd deployment utilizes, compared to the main stream of deployments around the globe. The other big concern is cooling. When you are talking about 20kW of power consumption in 18sqft of space, you are now creating so much heat that even liquid cooled cabinets become ineffective. If data centers need to be built to handle upwards of 1000 watts/sqft, data center facilities are going to be needing a nuclear power plant soon just to provide the power requirements...

Assuming 150 watts/sf is average and a cabinet occupies 30 square feet of floor space (which is on the high side) that's 4.5kW per rack. In the same facility, if you wanted 7.4kW delivered to the rack that rack would occupy 49.33sf of floor space. That's a LOT of wasted space. This leads me to believe that either my math is wrong or the 7.4kW per rack isn't actual power consumption (or a bunch of other possibilities.) Can someone help me understand the math used here? Thanks, -Dave 7.4kW per rack on average? Assuming 150 watts/sf is average and a cabinet occupies 30 square feet of floor space (which is on the high side) that’s 4.5kW per rack.
