WP#61 - Space Usage Effectiveness (SpUE)

Overview

This white paper proposes Space Usage Effectiveness (SpUE) as a metric of how effectively data centre space is used. It is dated 5 December 2014; the editor is David Wang (Teradata), with contributors from the China team.

SpUE extends the xUE metric family that includes PUE, CUE and WUE. The aim is for managers to assess space optimisation together with carbon, water and energy optimisation. That allows a comparison covering facility resources as a whole rather than energy efficiency alone.

The information comes only from the public description page of The Green Grid library; the full text requires signing in with a free account and is governed by the Terms of Use. The metric's formula and calculation details are therefore not part of this record.

Key points

1. Dated 5 December 2014; editor David Wang (Teradata), China-team contributors.
2. Introduces the SpUE metric for space usage.
3. SpUE extends the xUE family alongside PUE, CUE and WUE.
4. Intended to assess space optimisation together with carbon, water and energy.
5. Full text requires a free TGG account.
6. The metric formula is not part of this record.

Using it in design

• In the layout module, report space metrics (IT kW per m2 of white space, racks per m2, white-space ratio) next to PUE/WUE as a SpUE-style indicator.
• Compare alternative layouts on space, energy and water indicators together, not PUE alone.
• State in the report which space definition (white space, gross area) is used.

Who should read it

Designers doing layout and capacity planning, and managers who want to track facility resources together.
