Welcome to SNIA Emerald

I want to know more about the SNIA Emerald™ Power Efficiency Specification and how to do Emerald testing     I am interested in what SNIA offers in education and training on power efficiency measurement     I am a testing company and want to know more about the Recognized Tester Program
Give me an overview of EPA EnergyStar and other energy efficiency programs for storage     I want to how to test for V3.0     I want to see the newsletters and subscribe to receive more information

SNIA Emerald™ Specification V4, referenced by ENERGY STAR DCS 2.0, adopted by SNIA. Materials needed for testing are available here.

 

ISO/IEC 24091:2019 published (technically equivalent to SNIA Emerald™ V3.0.3)

 

The purpose of the SNIA Emerald™ Program is to provide public access to storage system power usage and efficiency through use of a well-defined testing procedure, and additional information related to system power. The measurement procedure, the SNIA Emerald™ Power Efficiency Measurement Specification, was developed and released, and is maintained by the Green Storage Technical Working Group under the guidance of the Green Storage Initiative (GSI) of the SNIA.

The SNIA Emerald™ Program provides an envelope of activities and elements that further advance the use of storage system measurement procedures and test metrics as documented in the SNIA Emerald™ Power Efficiency Measurement Specification. Activities include:

  • periodic comprehensive industry training on how to prepare and test a storage system for vendors and independent test labs;
  • joint industry stakeholder meetings with regulatory bodies for the reference and use of Power Efficiency Specification;
  • elevating awareness of industry and national regulatory testing programs and analysis of submitted test reports;
  • cross-industry alliances for testing tools, methods, and policy setting recommendations.

The SNIA Emerald™ Program is the focal point for the industry for SNIA Emerald™ Power Efficiency Measurement Specification, the Recognized Tester Program, and technical training for the SNIA Emerald™ test methodology.

SNIA Emerald™ Power Efficiency Measurement Specification

The SNIA Emerald™ Power Measurement Specification identifies metrics by which energy consumption and efficiency of storage networking products can be measured for the purposes of new product development, end-user customer evaluation, and regulatory standards development.

Relationship with the USA Environmental Protection Agency (EPA) ENERGY STAR Program

The SNIA Emerald Specification is a building block for national and regulatory testing programs driving energy efficiency. The United States Environmental Protection Agency (EPA) Energy Star Program for Data Center Storage references the SNIA Emerald Specification and publishes storage vendor system test reports for public use to aide IT procurement, IT planning, and IT operations.

“The EPA ENERGY STAR program is very supportive of the SNIA work on the storage system taxonomy and the test measurement methods contained within the SNIA Emerald Power Efficiency Measurement Specification,” said Robert J. Meyers, Data Center Products Lead, EPA ENERGY STAR. “They form an excellent starting point in the industry effort to understand and improve storage system energy efficiency. Additionally, the data generated using the Emerald test method will help drive a wider industry discussion on energy efficiency, testing methods, and efficiency metrics.”
