本文件描述了一种标准化方法，用于评估商业存储产品在运行和闲置状态下的能效。定义了一种分类法，根据操作配置文件和支持的功能对存储产品进行分类。描述了用于测量每个分类类别的功率效率的测试定义和执行规则；这些包括测试顺序、测试配置、仪器、基准驱动程序、IO配置文件、测量间隔和度量稳定性评估。定义了定性启发式测试，以验证几种容量优化方法的存在性。由此产生的功率效率指标定义为选定的稳定测量间隔期间的空闲容量或活动操作与平均测量功率的比率。

This document describes a standardized method to assess the energy efficiency of commercial storage products in both active and idle states of operation. A taxonomy is defined that classifies storage products in terms of operational profiles and supported features. Test definition and execution rules for measuring the power efficiency of each taxonomy category are described; these include test sequence, test configuration, instrumentation, benchmark driver, IO profiles, measurement interval, and metric stability assessment. Qualitative heuristic tests are defined to verify the existence of several capacity optimization methods. Resulting power efficiency metrics are defined as ratios of idle capacity or active operations during a selected stable measurement interval to the average measured power.
