Overview

This white paper from The Green Grid is dated 21 December 2016, and its editors are Lex Coors (Interxion) and Rob Bunger (Schneider). It introduces OSDA, the Open Standard for Datacenter Availability. OSDA is an availability classification and rating system designed to encourage energy-efficient and sustainable designs.

The system applies to both new designs and existing facilities and uses availability as its measure of resilience. It is non-proprietary, accepts contributions through TGG members and is a voluntary framework. These features make it an open alternative to classification systems that carry ownership rights.

The document is the first of a series of OSDA framework documents, so the detailed rating rules sit in later documents. The record rests only on the abstract on the TGG library page and contains no class definitions or calculation method.

EN 50600-1 and the Uptime Tier Standard are named as related standards. Because OSDA is voluntary, it creates no legal or contractual obligation; it is an option that designers can use alongside Tier or EN 50600 classes.

Key points

  1. Dated 21 December 2016; editors Lex Coors (Interxion) and Rob Bunger (Schneider).
  2. OSDA is an availability classification and rating system.
  3. Applies to new designs and existing facilities.
  4. Non-proprietary; accepts contributions via TGG members; voluntary framework.
  5. First of a set of OSDA framework documents.
  6. Related standards: EN 50600-1 and the Uptime Tier Standard.

Using it in design

  • In the reliability module, alongside Tier/EN 50600 classes, offer an availability-based rating that credits on-site renewables and alternative topologies.
  • Label the rating as a voluntary, open option.
  • State that class definitions must be taken from OSDA's later documents.
