Explore references on reliability, availability and redundant architectures. Review failure models, maintenance arrangements and system dependencies while keeping the evidence, methods and scope of each publication in view.
169–192 / 255
Caterpillar 2021
Warn when planned monthly exercise or normal running load is under 30% of rating, and recommend load-bank testing or a reduced set count.
Upsite Technologies blog 2019
Server catalogue entries should store the manufacturer's min/max inlet temperature and derive the ASHRAE class from it.
Eaton 2018
Add arc-flash attributes per switchboard (available fault current, clearing time, maintenance-mode/ZSI availability, working distance) and compute incident energy per IEEE 1584 for line and load side.
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.
Schneider Electric 2021
In a portfolio/edge module let users model multiple sites with availability (or tier), headcount served and severity (1-5), compute series availability for dependent sites and rank sites by downtime x severity.
arXiv preprint (University of Texas at Austin; formatted for IEEE Transactions on Power Systems) 2025
Model AI data-centre load as a persistent periodic forcing (0.3-1.5 Hz band, about 20% of peak fluctuating) rather than a ramp, and add oscillation analysis to the grid-interconnection study.
The Green Grid 2012
In the UPS module, model double-conversion and Eco/ESS modes with separate efficiency curves.
The Green Grid 2012
When users raise supply air above the ASHRAE recommended range, show both the cooling-energy saving and a reliability note (ASHRAE x-factor) instead of a hard error.
The Green Grid 2013
Compare THDi and THDv against IEEE 519 limits at the PCC rather than demanding near-zero values.
The Green Grid 2015
Offer a reduced-conversion topology scenario.
The Green Grid 2016
Store PSU ride-through (ms) as a catalog field for IT equipment.
The Green Grid 2016
Catalog the ride-through time per PSU.
The Green Grid 2016
In the reliability module, alongside Tier/EN 50600 classes, offer an availability-based rating that credits on-site renewables and alternative topologies.
Eaton 2021
In the asset/lifecycle module store the installation year per UPS and battery, and project replacement dates from the component table defaults.
CDC / National Institute for Occupational Safety and Health 2019
Write the MTBF and MTTR assumptions beside every availability estimate.
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 2021
In the operations module attach a maintenance strategy and default PM interval (quarterly/semi-annual/annual) to each catalog asset class, with a condition-based monitoring option.
Eaton 2016
Add a designLifeYears catalog parameter per equipment type, default to the range midpoint, and drive a TCO/refresh timeline from it.
Schneider Electric 2024
Add an efficiency-degradation factor to the opex model for run-to-fail operation (+19%/+29%/+39%/+51% cooling energy in years 2 to 5) against the maintained case.
Open Compute Project Foundation 2023
Require each vendor to fill in the parameters of importance tables for cold plates, hoses, quick disconnects, loops, manifolds and CDUs so offers can be compared.
Schneider Electric 2011
When topology is 2N but some loads are single-corded, require a rack ATS per single-corded device by default.
Schneider Electric 2016
Offer N, isolated redundant, N+1, distributed redundant (catcher/STS), tri-redundant, 2N and 2(N+1) in the topology library, and label availability values as comparative rather than absolute.
Vertiv 2017
In A/B (2N) racks keep each feed's design load at or below rating x 0.8 (80%-rated breaker) x 0.5; for single phase usable kW = V x I x 0.8 x 0.5.
