SNIA Emerald™ Power Efficiency Measurement Specification

The SNIA Emerald™ Power Efficiency 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. All versions of theMeasurement Specification are available for download.

As of September 11, 2017, the SNIA Green Storage Technical Working Group released Specification Version 3.0.1 and this is now available for download. The SNIA Green Storage Initiative and Green Storage Technical Working Group are working with the EPA ENERGY STAR® Program's Data Center Storage (DCS) Program to add testing of file access storage devices, as defined in SNIA Emerald V3.0.1, to the ENERGY STAR® Program in the upcoming ENERGY STAR® DCS Version 1.1 Specification for Data Center Storage. The SNIA Emerald™ Specification V3.0.1 is a major extension of the V2.1.1 specification that:

  • Adds a test methodology for file access storage devices based on the SPEC® SFS2014 benchmark, substantially expanding the range of testable storage devices;
  • Clarifies and updates many elements of the specification based on usage experience;
  • Improves organization of the specification;
  • Retains all the major elements of V2.1.1 including the storage taxonomy and the block IO test methodology.

Access and download SNIA Emerald Specifications as approved SNIA Architecture, versions 3.0, 2.0, 1.0.

SNIA plans to submit SNIA Emerald V3.0 to the International Standards Organization (ISO) in the second half of 2018 for consideration as a recognized international standard, for the purposes of any regulatory body to reference a standard test and measurement methodology for storage systems to measure energy usage with consistently referenced industry metrics.
