Everyone is going green. A new Data
Center at Syracuse University
has been claimed by IBM as the "greenest" yet.
The new 12,000 square foot facility that recently opened
offers a comprehensive approach to energy efficiency utilizing DC power
distribution to power the IBM z10 mainframe and high efficiency 415 V 3-Phase power
distribution units to power the devices within the cabinets.
Furthermore, the Green
Data Center
will operate off the grid while still serving as the primary computing facility
at Syracuse University.
Estimated cost for the Green Data Center is $12.4 million with funds being
contributed from the New York State Energy Research and Development Authority
(as well as $500,000 from the New York Senate.
IBM donated an estimated $5 million in equipment, support and design.
A key component in the design of Syracuse’s
Green Data Center
is 415 V 3-Phase AC power. Though none
of the specific technologies used in the Syracuse
facility are new, the use of 415 V 3-Phase AC power, which is used throughout
most of the world, is relatively new to North American Data Centers and offers
a number of advantages. For increased efficiency 415 V 3-Phase power has two
main advantages; 1) in incoming power does not have to converted all the way
down to 120 V before being delivered to the cabinets saving cost and power
losses during the conversions and 2) by allowing higher voltages to be
delivered to the devices within the cabinet they operate at greater
efficiencies. Typically there is at least a 3-5% overall efficiency gain using
415V 3-Phase power over typical 208 V 3-Phase power along with a reduction in
infrastructure and other costs.
Also for high density applications a 415 V 3-Phase 30 A power whip delivers the
same amount of power (17.3 kW derated) as a North American 208 V 3-Phase 60 A
power whip. But there are a number of advantages with distribution of 30 A
power over 60 A power like smaller cables and less expensive plugs and
connectors.
