Materials for Testing with the SNIA Emerald™ Specification V3.0

Note: The SNIA Emerald™ Power Efficiency Measurement Specification Version 3.0.2  was adopted by the SNIA on May 23, 2018. This minor update to Measurement Specification Version 3.0.1 corrects some inconsistencies in timing requirements for recording data and clarifies the tables in Annex B.

Note: The SNIA Emerald™ Power Efficiency Measurement Specification Version 3.0.1 was formally approved by the SNIA on September 11, 2017. The most significant change (relative to Version 2.1.1) is the addition of test procedures for file access storage systems. These are based on using SPEC SFS 2014 as the workload driving the tests. The EPA Energy Star Data Center Storage Specification V1.1 includes file access devices with testing based on Measurement Specification Version 3.0.1.

This page provides access to the materials needed to perform power efficiency measurements based on Measurement Specification Version 3.0.2.

A revision history is materials listed on this page is available.

Specification

The SNIA Emerald™ Power Efficiency Measurement Specification is developed and maintained by the SNIA Green Storage Technical Working Group. Measurement Specification Version 3.0.2 dated May 23, 2018 is available here for download.

SPEC SFS 2014

SPEC SFS 2014 is a file-based I/O benchmark, developed by the Storage Performance Evaluation Corporation (SPEC), referenced by the Measurement Specification for use in Emerald testing of file access storage systems.

SPEC SFS 2014 can be purchased from SPEC. For information on purchasing this tool, click here.

A presentation Using SPEC SFS with the SNIA Emerald Program for EPA Energy Star Data Center Storage Program is available.

Training material on SPEC SFS 2014 is available from SPEC here.

File Access IO Load Driver Configuration File

Testing file access on-line and near-line devices requires the use of the File Access IO Load Driver Configuration File as a template for creating configuration files that control the file testing through SPEC SFS 2014. The current version is 2017_08_30.

Vdbench

Vdbench is a block-based I/O workload generator, developed by Oracle, referenced by the Measurement Specification for use in Emerald testing of block access storage systems.

Version 5.04.05 of Vdbench shall be used when testing using Measurement Specification Version 3.0.2.

Vdbench Script

The Measurement Specification requires use of the the Vdbench Script for Online and Near-Online testing provided here to control the Vdbench workload generator during block access testing of Online and Near-Online storage systems. The current version is 2018_06_13.

The Measurement Specification requires use of the the Vdbench Script for Removable and Virtual Media Library testing provided here to control the Vdbench workload generator during block access testing of Removable Media Library and Virtual Media Library storage systems. The current version is 2017_07_26.

COM Test Data Set Generator

The Measurement Specification requires use of the COM Test Data Set Generator software to generate data sets for using in testing the existence of various COM features. The current version is V1.17 dated April 13, 2016.

What Has Changed?

The What has Changed? SNIA Emerald™ Measurement Specification V2.1.1 to V3.0.1 document provides a summary overview of the changes made between Measurement Specification Versions 2.1.1 and 3.0.1 and describes the significance and impact of these changes on Emerald testers.
