Why ENERGY STAR?

Storage is a major concern for data center managers. In fact, 28% of data center managers identified storage growth as the trend having the greatest impact on their data operations. In 2012, most data centers report data storage growth at 10 to 24% annually.⁵

Data storage purchases are complex decisions that involve consideration of many factors (e.g., uptime, retention policies, automation, networking options, disaster recovery, future growth, options in the cloud, physical space limitations, etc.). By selecting ENERGY STAR certified data storage, one part of that purchasing decision — energy efficiency — can be done quickly and easily.

In addition, one watt-hour of energy savings at the storage level results in roughly 1.9 watt-hours of facility-level energy savings.⁶ These additional savings stem from reducing energy waste in the power infrastructure (e.g., power distribution unit, uninterruptible power supply) and reducing 24/7 energy needed to cool the waste heat produced by data storage.
