Storage Device-Level Power Efficiency Measurement for Cloud, Datacenter & Enterprise Storage

Data storage power efficiency measurements are essential for evaluating power, performance and storage operating costs.

Data center operating costs include compute, network, storage, and facility-side systems and resources. The ISO/IEC 24091:2019 IT Specification for Data Center Storage (ISO 24091) Standard is based on the SNIA Emerald Power Efficiency Measurement Specification V3.0 created by the SNIA Green Storage Technical Work Group (Green Storage TWG) for measuring enterprise storage system-level power efficiency. The Green Storage TWG is now developing a complementary storage device-level spec for a standardized, easy-to-use, cost-effective method for power efficiency measurement.

This white paper describes storage device-level (individual storage drive) power efficiency test methodologies, the device test harness, the use of workloads, calculating metrics and reporting device test results. The Green Storage TWG is seeking industry regulatory bodies as well as technical and supply chain stakeholders to participate in the further development of the device-level spec with the contribution of technical resources, short-term loan of in-production storage devices and IO capture of real world enterprise application workloads.
