What the study found

The study introduces the Self-Assessment Tool (SAT), a unified framework for evaluating data center thermal and energy performance from IT and cooling data. It also supports imported historical data and can generate standardized assessment reports.

Why the authors say this matters

The authors say the approach addresses the challenge of collecting data and calculating key performance indicators, or KPIs, within the reporting period. The study suggests the framework could support comprehensive periodic assessment reports for data centers.

What the researchers tested

The researchers developed SAT as a modular and extensible framework for data center evaluation. They tested it on two pilot data centers, one in Denmark and one in Switzerland, using real-time and historical datasets from data monitoring systems and external sensors.

What worked and what didn't

SAT calculates standardized thermal KPIs, including RCI, RHI, RTI, RI, and LI, and energy KPIs, including PUE and COP, from real-time and historical data. In the pilot demonstrations, it automatically generated time-series visualizations, rack-level thermal maps, and energy-efficiency classifications. The abstract does not describe any specific failures or components that did not work.

What to keep in mind

The summary does not provide detailed limitations beyond noting the complexity of data collection and KPI calculation in the reporting period. The validation described here is limited to two pilot data centers, so the abstract does not state broader performance beyond those examples.

Key points

  • The paper introduces the Self-Assessment Tool (SAT) for data center thermal and energy evaluation.
  • SAT uses IT and cooling data from monitoring systems, and it can also import historical datasets.
  • The tool calculates standardized KPIs such as RCI, RHI, RTI, RI, LI, PUE, and COP.
  • In two pilot data centers in Denmark and Switzerland, SAT generated reports with visualizations, thermal maps, and efficiency classifications.
  • The framework is described as modular, extensible, and deployable as a standalone or web-based service.
