Overview

The Green Grid WP 82 is dated 16 October 2020. The paper reviews the method the European Commission (EC) proposed for verifying a server's declared operating condition class. The classes are ASHRAE-style A1-A4 classes.

The paper responds to an EC request for test methods to verify the operating condition class. The EC proposal is to test with SPEC SERT (ISO/IEC 21836) for at least 16 hours. A unit complies if SERT reports valid results over the 16-hour test.

The Green Grid proposes a modification to the EC methodology. This is an example of industry review of a regulator's proposed method, and it reflects the debate over what a server's declared class means in real conditions.

Related documents are Regulation (EU) 2019/424 and ISO/IEC 21836. As a limitation, the details of the proposed modification are not covered on this page.

Using it in design

  • In the server catalogue, store the declared operating condition class (A1-A4).
  • Validate that the room design envelope does not exceed the lowest class among the installed IT equipment.
  • Where class data is missing, use a conservative assumption and warn the user.
