Eaton EMAA13 User Manual

Two key trends have emerged in the data centre: the demand from 

today’s IT equipment for more power, and the increasing cost of that 

power. Couple these with the worldwide growth in demand for data 

centres and IT servers, and it is clear that data centre managers 

are facing growing pressure to manage and optimise their available 

power for growth, at the same time as managing the increasing 

associated costs.

To help them achieve this, they need an accurate view of the power 

and energy being consumed in the data centre – from row to rack, 

and right down to the individual server level. Only then can they truly 

understand the power usage and optimise the available power.

Eaton Managed ePDU

Power usage effectiveness (PUE) is a metric used to 

determine the energy efficiency of a data center and is 

determined by dividing the amount of power entering a data 

center by the power used to run the computer infrastructure 

within it. These ePDUs provide outlet level power 

consumption for Level 3 PUE calculations.

Level 1:  Basic, uses UPS readings

Level 2:  Intermediate, uses PDU readings

Level 3:  Advanced, uses server/outlet readings

PUE has been defined by the Green Grid
