Abstract
This technical white paper describes storage device-level (individual storage device) power efficiency test methodology, the device test harness, the capture and use of IO workloads, calculating power efficiency metrics, and reporting device test results. The test methods are applicable to HDD and solid state storage devices (SDD) that have industry standard interconnects. This white paper lays a foundation for a forthcoming 2023 technical specification. This specification will be complementary to the system-level ISO/IEC 24091:2019 IT Specification for Data Center Storage (ISO 24091) Standard based on the SNIA Emerald™ Power Efficiency Measurement Specification V3.0/V4.0 .
