Overview

This white paper was prepared by The Green Grid Power Task Force and published on 23 October 2007. It discusses the qualitative differences between seven power distribution configurations that are found in US and Canadian data centres or may be used in future.

The paper's central claim is that each configuration's advantages and disadvantages affect all aspects of the facility. Selection therefore cannot be limited to the electrical diagram; it has to be weighed together with cost, efficiency, redundancy and operations. The document provides a basis for a topology comparison view.

The information here comes only from the public description page of The Green Grid library; the full text requires registration and is governed by The Green Grid Terms of Use, so details and figures for the seven configurations are not included. The paper dates from 2007 and may be out of date on newer technologies and efficiency data.

Key points

  1. Dated 23 October 2007 and authored by the TGG Power Task Force.
  2. Discusses qualitative differences between seven power distribution configurations.
  3. The configurations are those found in the US/Canada or potentially used in future.
  4. Each configuration affects all aspects of the facility.
  5. Download requires signing in with a free TGG account.
  6. It is a qualitative comparison; no loss figures are given in this record.

Using it in design

  • In the electrical topology library, tag topology templates (480/208 V AC, 415/240 V AC, DC options) with qualitative pros and cons.
  • Let the efficiency calculator quantify conversion losses for each topology.
  • Justify the topology decision by its effect on the whole facility, not only the electrical diagram.
