Many newer uninterruptible power supplies (UPS) systems have an energy-saving operating mode known as “eco-mode” or by some other descriptor. Nevertheless, surveys show that few data centers actually use this mode, because of the known or anticipated side effects. Unfortunately, the marketing materials for these operating modes do not adequately explain the cost/benefit tradeoffs. This paper shows that eco-mode provides a reduction of approximately 2% in data center energy consumption and explains the various limitations and concerns that arise from eco-mode use. Situations where these operating modes are recommended and contraindicated are also described.
