WP#86 - Energy Efficient Data Center Storage: An Assessment of Storage Product Power Efficiency
The Green Grid · TGG Data Center Energy Efficiency Technical Working Group
This Green Grid white paper recommends to regulators which criteria and test metrics should be used to assess the power efficiency of online data storage products. It replaces WP#77.
On this page
Overview
The document is dated 13 July 2022 and replaces WP#77. Its author is the TGG Data Center Energy Efficiency Technical Working Group.
The work serves two functions. First, it explains how online data storage products work and describes their characteristics; keywords include SNIA. Second, it makes recommendations to regulators on which criteria and test metrics should be used to assess storage power efficiency.
As context, the paper supports the approach that storage product power efficiency should be judged from standardised test data rather than label values. The related sources are SNIA Emerald and Regulation (EU) 2019/424.
As a limit, the summary gives neither the details of the recommended metrics nor numerical thresholds. In practice SNIA Emerald test results and the text of the relevant regulation should be the basis.
Key points
- Dated 13 July 2022; replaces WP#77.
- Makes recommendations to regulators on criteria and test metrics.
- Describes characteristics of online data storage products; keywords include SNIA.
- Author: TGG Data Center Energy Efficiency Technical Working Group.
- Related: SNIA Emerald and Regulation (EU) 2019/424.
- The record rests on the public summary only.
Using it in design
- In the storage catalog, capture power per capacity or performance from SNIA Emerald-style test data rather than nameplate.
- Use standardised test metrics as the criterion when comparing storage products.
- Note the relevant EU regulation (2019/424) as a reference in storage energy calculations.

Report from the Commission to the European Parliament and the Council on the energy efficiency of data centres in the EU - COM(2026) 500 final
Set the PUE target for new designs against the bands in the report (below 1.2 excellent, above 1.5 needs improvement) and possible future minimum-standard thresholds, noting that the 500-1000 kW class averaged 1.64.
- EU data centres consumed 68 TWh of electricity in 2024, expected to reach 114 TWh by 2030 (3.2% of EU electricity).

Translate PUE and WUE targets into A-G classes: class A needs a design PUE of 1.15 or below and WUE of 0.1 or below; the class D boundary is 1.5 and 0.6. Write the class target into the design specification.
- WUE classes: A <= 0.1; B 0.1-0.2; C 0.2-0.4; D 0.4-0.6; E 0.6-0.8; F 0.8-1.0; G > 1.0.

As labels will be issued every year from 15 August 2027, set PUE and WUE class targets (Annex I) at design stage for new and existing sites and build the metering infrastructure to the reporting requirements.
- Labels are generated automatically by the European database every year from 15 August 2027 and are publicly available electronically in all official Union languages.
