Rack PDU (Power Distribution Units)
12
It is rare to have a rack discussion
without also talking about the rack
PDU. According to Data Center Users’
Group™ ndings, the average power
consumption in the Enterprise Data
Center is now approximately 8kW
per rack, with projections to grow to
10kW per rack by 2012. In the Small
to Medium Business space, (SMB)
the average today is 6kW per rack.
Couple this increased power density
with various monitoring and control
needs, and the issue of proper
PDU selection becomes critical
to effective Data Center
infrastructure deployment.
The Emerson Network Power family
of rack PDU features varying levels of
monitoring and control. These PDUs
offer choices of input phase, input/
output ampacity and input/output
voltage to provide you with the best
solution for the application you are
facing today, or foresee in the future.
