SNIA Emerald Specification
The SNIA Emerald™ Program Power Efficiency Measurement Specification, is a storage specification developed and maintained by the Storage Networking Industry Association (SNIA) and cross-referenced by the Environmental Protection Agency’s EnergyStar program. The specification consists of a storage types taxonomy, system under test workload and energy measurement method, measured metrics for active and idle operational states, and presence tests for capacity optimization technologies. The measured metric data is generated through the use of well-defined standard testing and data reduction procedures prescribed in the SNIA Emerald™ Specification. This data quantifies storage system power efficiency for typical types of enterprise datacenter workloads and helps IT professionals make storage platform selections as part of an overall Green IT and sustainability objective.
SNIA’s ongoing collaboration with the EPA has helped to shape the Energy Star Data Center Storage (DCS) Specification. The EPA DCS specification cross-references the SNIA Emerald™ Specification as the test and measurement methodology - See http://www.energystar.gov/index.cfm?c=products.pr_crit_data_storage_centers

Timeline
- 2007 SNIA organized its focus on energy efficient storage, best practices, industry education and requirements with the formation of the Green Storage Technical Working Group (TWG) and Green Storage Initiative (GSI)
- 2008 SNIA Green TWG engages with EPA on Server and Storage ENERGY STAR Specifications. SNIA, SNIA GSI and SNIA Green TWG, advocates for a separation of ENERGY STAR specifications for servers and storage due to the unique differences and characteristics of servers and networked storage.
- 2008 SNIA Green TWG held two engineering lab workshops to validate test and measurement methodologies for several classes of storage systems. Additionally, characterized the size and impact of enterprise storage features for reliability, availability, supportability, capacity optimization, and data protection.
- 2009 SNIA Green TWG releases the Green Power Measurement Technical Specification, detailing the measurement of Idle storage system power (GreenPower_V018)
- 2009 EPA announces it plans for an ENERGY STAR Specification for Enterprise Data Storage Equipment. The initial framework drafted was based on the EPA ENERGY STAR Server specification and references the SNIA GreenPower_v018 specification (idle measurement) and future pending SNIA specific active system test and measurement procedures.
- 2009 SNIA with ECOS measure a wide sample of storage power supplies to validate their test methods and protocols in conjunction with EPRI as part of the 80PLUS program.
- 2010 EPA Releases the first draft of the ENERGY STAR for Data Center Storage, a working draft to engage industry discussion and to review storage system power consumption measurements.
- 2011 SNIA releases SNIA Emerald Power Efficiency Specification version 1.0.0 which expands on Green Power Measurement Specification including comprehensive Taxonomy for classes of storage, Idle and Active Test Measurement for block IO, and Capacity Optimization Methods presence tests.
- 2011 EPA Releases draft 2 of the ENERGY STAR for Data Center Storage, which cross-references the SNIA Emerald Power Efficiency Measurement Specification Version 1.0
- 2011 SNIA GSI launches the SNIA Emerald Program for publicly posting Test Data Reports and providing industry-wide support for any manufacturer or lab testing with the SNIA Emerald Test Specification.
- 2012 EPA Releases draft 3 of the ENERGY STAR for Data Center Storage, which references the SNIA Emerald Power Efficiency Measurement Specification Versions 1.0
- 2013 SNIA releases SNIA Emerald Power Efficiency Specification version 2.0.2 along with tools for running tests, correlating test data, and preparing test data reports.
- 2013 EPA concludes industry discussion with draft 3 and releases to the industry ENERGY STAR for Data Center Storage Version 1.0 with an effective date of December 2, 2013 to receive test submissions.
- 2014 EPA Releases an update to ENERGY STAR Data Center Storage Version 1.0. Vendor product test data is received and posted in the EPA program listing repository.
