NVIDIA 2025
Add a single-ended 800 VDC distribution option to the electrical model, with rectifier blocks of ~1.5 MVA (LV) and up to 7.5 MVA (MV/SST) and the stated efficiencies.
NVIDIA 2026
Define four electrical templates for AI halls: AC baseline (480 VAC, 100 A whips, 4M3), Power Rack, 2 MW Power Center and 4.8 MW DC Power Block with 4+1 catcher.
IEEE Access (Institute of Electrical and Electronics Engineers (IEEE)) 2021
Set the number of spare PSUs/servers in a rack with a LOWP-style calculation from target service reliability and the load duration curve, avoiding unnecessary overprovisioning.
Open Compute Project Foundation 2021
Give rear-door HX catalog entries rated kW, fan power, coolant inlet temperature, flow, pressure drop and active/passive type.
Data Center Frontier 2025
Model two separate network fabrics (front-end and back-end) in AI hall templates with separate pathways and fiber counts.
arXiv preprint (University of Alberta) 2025
Include rack-level templates for AI racks (32-34 kW air-cooled, 73-132 kW liquid-cooled NVL) with per-GPU power.
arXiv preprint (Cadence Design Systems) 2026
For layout iteration and add-load what-ifs, a surrogate that predicts only cabinet-inlet temperature (the compliance quantity) is cheaper and more accurate than full-field surrogates.
Upsite Technologies blog 2021
In layout rules, allow perforated tiles only in cold aisles.
Schneider Electric 2016
Offer reference architectures 'traditional 2N', 'OCP 1N', 'OCP 2N (no central UPS, 1N BBU)' and 'simplified 2N mixed-load (single UPS path)' in the topology builder; let a rack type declare power shelf, BBU runtime and PSU redundancy.
BICSI (via Cabling Installation & Maintenance) 2019
Keep BICSI 002 edition history (2014, 2019, 2024) in the standards registry for projects citing older editions.
ASHRAE 2024
Use Book 2 (IT Equipment Power Trends) for default kW-per-rack growth projections.
Schneider Electric 2011
In layout validation, raise an error when adjacent rows of front-to-back equipment face the same direction, and a warning for perforated tiles or supply diffusers in a hot aisle.
Data Center Frontier 2024
Support hybrid air/liquid halls and rack-level or near-rack backup power topologies in the design library.
Schneider Electric 2022
Add site type (legacy telco, distributed cloud, MEC), environment class and power type (AC, -48 V DC, hybrid) to the project template.
Open Compute Project Foundation 2025
Give rack power distribution components fields for rated current, maximum voltage drop and cooling method.
Energies (MDPI AG) 2022
When modelling a server as a porous block in room-scale CFD, use Darcy-Forchheimer coefficients fitted to a resolved pressure-drop curve rather than generic assumptions such as porosity 0.5.
Schneider Electric 2014
Capture peak kW/rack and the peak-to-average ratio as well as the average, and express density in W/rack instead of W/m2.
Energies (MDPI AG) 2023
In hybrid-cooled racks, represent a cold-plate server as a compact model in room-scale CFD: model the share of CPU heat going to the cold plate (~97%) and the residual escaping to air separately.
Schneider Electric 2011
Add an airflowPattern field to the equipment catalogue (front_to_back, back_to_front, side_to_side, side_to_back) and fill it in for switches and routers first.
IEEE Transactions on Components, Packaging and Manufacturing Technology (Institute of Electrical and Electronics Engineers (IEEE)) 2021
For high-heat-flux chips, compare the point at which air cooling throttles (here 3.3-4 GHz) with the clock-rate gain from cold plates or 2P immersion (41-51%) in cooling technology selection.
Uptime Institute Journal 2014
When only perimeter CRAC/CRAH cooling is selected, warn above about 6 kW average per cabinet and require row, rack or liquid cooling for 20 kW and above.
