Topic guide
Explore sources on rack layouts, power density and IT equipment interfaces. Review technical notes to understand how mechanical, electrical and cooling requirements meet at the rack level.
121–144 / 191
Vertiv 2026
Give the rack/pod model a liquid fraction (default about 70% for direct-to-chip) so residual air load is computed automatically.
Electronics (MDPI AG) 2025
In rack power-chain efficiency calculations, treat the number of stages and each stage's efficiency as separate inputs, and show the benefit of fewer stages at load points (low and high current).
Schneider Electric 2017
Give the module catalog functional block, form factor, indoor/outdoor rating, walk-in flag, shipping sections, footprint and height.
Data Center Frontier 2022
Implement the CFM = kW x 3412 / (1.08 x delta-T) check per rack and per tile.
Uptime Institute 2020
Preset the default 'typical' rack density for enterprise halls at around 8 kW, and offer explicit high-density options.
Uptime Institute 2023
Keep the default rack-density preset for enterprise facilities below about 6-8 kW.
Uptime Institute 2024
Compare the design rack density with the industry distribution; treat values above 30 kW as far above norms and trigger liquid-cooling and floor-loading checks.
KPMG Türkiye 2025
For racks above about 70 kW, warn that air cooling is insufficient and require a liquid-cooling path.
Panduit (Ning Liu), hosted by Cisco Year not stated
Use ER, MDA, HDA and EDA as physical planning roles and distinguish backbone from horizontal cabling.
Rittal 2013
Model cooler redundancy explicitly: 2N may come from two units or one unit with dual independent power and water feeds, so catalogue entries need an 'internal redundancy' field.
Rittal 2012
Catalogue rear-door coolers with a passive/active flag, kW capacity and air-side pressure drop.
Open Compute Project Foundation 2022
Offer an 'OCP Ready' compliance profile that checks the delivery path (dock, ramps, door heights), floor load classes (uniform, concentrated, rolling), 3-phase IEC/NEMA rack circuits, hot/cold-aisle containment and generator load-acceptance time relative to BBU autonomy.
Open Compute Project Foundation 2026
Use as background for the 800 VDC and sidecar topology option.
Rittal 2017
Catalogue close-coupled coolers by type (inline row, closed-loop rack, rear door, DX rack), rated kW, width, footprint, maximum air delta-T and water/refrigerant inlet temperatures.
Rittal 2014
Keep PDU catalogue fields for phases, input A, max kW, outlet types, ambient rating, metering accuracy, relay type and management protocol (SNMPv3).
The Green Grid 2009
In rack and IT load entry, let users enter measured or vendor-calculator power instead of nameplate.
The Green Grid 2014
In the layout module, report space metrics (IT kW per m2 of white space, racks per m2, white-space ratio) next to PUE/WUE as a SpUE-style indicator.
The Green Grid 2017
In capacity planning, track ITE power utilisation (actual versus provisioned) per rack and hall.
The Green Grid 2023
Add a 480Y/277 V-to-rack option with 277 V PSUs and no PDU transformer to the electrical topology library.
ASHRAE 2023
Evaluate all applicable inlet conditions (temperature, moisture, dew point, altitude) together.
Schneider Electric 2026
Add a distribution architecture option for AI halls: AC 415/240, 48 VDC busbar, 800 VDC sidecar, 800 VDC centralized.
BICSI 2024
Offer BICSI classes as an alternate standards profile alongside Uptime/TIA/EN, with an F1~Tier I/Rated-1/Class 1 ... F4~Tier IV/Rated-4/Class 4 table labelled 'conceptual equivalence only'
Telecommunications Industry Association 2024
In a 'TIA-942' standards profile, let users pick a rating per discipline (for example electrical Rated-3, mechanical Rated-3, telecom Rated-2)
Schneider Electric 2013
Use this paper as the template for the Design Basis form: target average kW per rack, peak kW per rack (default 2x average), density uncertainty (default 15%), managed power ratio (default 0.7) and reserve space (default 15%).
