The Energy Star certification for data centers is moving forward with an expected announcement on final standards expected soon. In the meantime, EPA is moving forward with a specification for certifying data center storage devices such as enterprise hard drives and SSDs. The task is quite complicated, as you might imagine. Unlike an appliance such as a desktop computer or printer, data center storage efficiency can depend on any number of variables such as configuration, controllers, power supplies and controlling software. For that reason, Specification 1.0 is necessarily complex.
EPA has made some good progress since its announcement about a year ago that it was pursuing this program. Most recently, EPA has been involved in an effort to collect data from December last year until March to help it understand the relationship between hardware/software configuration and energy efficiency, active and idle state performance, and sensitivity to single-configuration changes such as hard disk and controller types. EPA has released the results of this stage of data collecting. It's worth a read if you're technically inclined -- there's some interesting and surprising results on how multiple factors can influence energy efficiency.
