LATEST INTELLIGENCE an industry we quickly moved on from single phase 120-volt inputs , spent several years at single phase 208 volts , moved into three phase 208 volts , and on to other voltages , like 415 volts . The voltage was coming up , and the current , protective devices , and conductor sizes were all going down . Select applications in the traditional data center environment started ticking up , and per rack power would start to increase to 10 – 20 % of the overall environment . Designs began to bifurcate into density and availability zones where we could leverage power distribution and heat rejection technologies based on the various power densities required in an overall space . All the while utilization was lagging design , presenting an inefficient balance on space utilization , and mechanical and electrical systems .
Power design
The integration of AI into data centers has significantly shifted power requirements – projections show a 50 % increase in the power footprint of a traditional data center by 2025 . AI servers demand power levels surpassing traditional servers to support advanced AI algorithms , data processing , and GPU-intensive workloads at a rate 3 – 7X higher . Design criteria has transcended the above whereby entire facilities are starting with a basis of design cabinet 17kW and higher . Now the voltage and rack density in kW have increased so too does the current . Current RFPs are calling for 17.3kW to more than 50kW per cabinet . p
