Open Compute Project Foundation 2026
Add a sidecar power-rack block (600/711 mm wide, about 1200 mm deep, 6000 lb) to AI row layouts with its own floor-load and clearance checks, and model +/-400 VDC distribution from it to IT racks.
Applied Sciences (MDPI AG) 2024
Make hot-aisle back pressure (hot-aisle pressure above cold aisle) a design input in contained aisles; server inlet temperature rises once back pressure reaches the fans' free-delivery point.
Buildings (MDPI AG) 2023
For hot-spot removal, before choosing lower supply temperature or higher airflow outright, compare the COP drop (3.2 to 2.6) and the energy difference (20.1% and 4.2%) with a rack-specific air distribution option.
NVIDIA 2025
Define the cluster template with SU = 8 NVL72 racks at 1.2 MW IT; auto-place SUs in rows following the reference rack layout, allocating ~150 kW per compute rack plus network racks.
NVIDIA 2026
Add the GB300 NVL72 rack to the catalog at 142 kW max, OCP ORv3 (OU) form factor, 8 x 33 kW power shelves, liquid cooled with leak detection; model ancillary network racks as EIA/AC.
Open Compute Project Foundation 2015
Add an ORV2 rack catalogue entry (600 x 1067 x ~2210 mm, 48 mm OpenU, 500/1400 kg IT-load ratings) so floor-loading calculators can use the correct footprint and point loads.
Open Compute Project Foundation 2023
Use 3 kW, 4 minutes and 6 hours recharge as default parameters for ORV3 BBU modules in the rack-power calculator.
Open Compute Project Foundation 2022
Model ORV3 in-rack BBU as an alternative to a central UPS and check that generator start and transfer time fit inside the roughly 4-minute window at rated load per shelf.
Open Compute Project Foundation 2026
Add a high-power ORV3 feed type (60 A 480 V / 63 A 400 V IEC 60309) to the busway/receptacle catalogue and size each whip at 48 A continuous in North America for power-shelf capacity checks.
Open Compute Project Foundation 2022
Add ORV3 whip feed types (NA 277/480 V L22-20P 20 A, EU 400 V IEC 60309 32 A) to the power-distribution catalogue so busway tap-off and receptacle schedules can be generated per rack.
Open Compute Project Foundation 2026
Add an ORW rack family whose footprint, height and payload come from the chosen design specification rather than fixed defaults, prompt users for those values, and warn that floor-loading and aisle-pitch checks depend on them.
Beca 2026
Allow mixed-density zones within one hall, each with its own density assumptions.
Frontiers in Energy Research (Frontiers Media SA) 2023
With active tiles, always seal under-rack gaps; if left open, low pressure at the tile surface pulls hot air in under the rack and worsens the lower servers.
Schneider Electric 2015
Add rack catalog fields: width (600/750/800 mm), vertical cable channel capacity, roof/base cutouts and a 'networkRack' flag.
arXiv preprint (Microsoft Azure) 2023
In the power planner, apply different diversity and oversubscription factors by workload: inference rows can be provisioned below sum-of-nameplate (for example peak about 80% of provisioned), while training rows should assume near-coincident peaks with only about 10% headroom.
Schneider Electric 2024
For every rack, row and upstream device store design maximum supply, design maximum demand (nameplate or as-configured) and measured actual where available; enforce supply >= demand at each hierarchy level including under N-1.
Schneider Electric 2013
Warn when rack branch-circuit load exceeds 80% of breaker rating.
Legrand 2015
In the PDU catalogue keep fields for input (V, A, phases), metering accuracy class and operating temperature rating, using 60 C as the hot-aisle reference.
arXiv preprint (Microsoft / OpenAI / NVIDIA) 2025
For AI-training halls, carry a 'synchronous load' flag and capture utility time-domain (MW/s ramp up/down, dynamic range) and frequency-domain (critical band, spectral cap) limits as interconnection inputs.
Schneider Electric 2011
Record the cord count (single or dual) of each IT device in the rack model and compute the single-corded share.
BICSI ICT Today 2026
For AI templates, default to single-mode fiber, high-count trunks and dedicated back-end fabric pathways.
IEEE 2017
Include hose, quick-disconnect and fitting losses explicitly in the tool's rack-level hydraulic calculations, not just cold-plate pressure drop.
7x24 Exchange Magazine 2025
Adopt these category codes (LD...EHD) as a rack density class derived automatically from kW/rack.
Uptime Institute Journal 2020
Ask users for modal and peak rack density separately, not just the average, and size cooling and power for the peak cluster.
