Copyright 2012 - Green Revolution Cooling Power Savings “What we are seeing is a significant saving in terms of electricity. I would say it’s not impossible to go up to a factor of two [power allocated to servers in a given data center]” Laurent Clerc, VP of Information Technology Copyright 2012 - Green Revolution Cooling

Power Savings Example Typical Installation Savings This slide needs to be fixed and improved mPUE < 1.03, any climate Copyright 2012 - Green Revolution Cooling

Copyright 2012 - Green Revolution Cooling Retrofit Savings “We saturated the power envelope of this room by putting twice as many systems as we would normally have, if it had a normal way of cooling systems.” Laurent Clerc, VP of Information Technology Copyright 2012 - Green Revolution Cooling

How to Nearly Double Your Data Center Server Capacity Retrofit with GRC Servers take ½ the floor space Reallocate MEP power to servers (add battery backup if necessary) Add 80% more servers into the same data center Copyright 2012 - Green Revolution Cooling

Data Center Operations “Today there is not really much difference between managing this room [with the CarnotJet” and managing another traditional air based computer.… there’s no noise, almost no noise, the temperature is very reasonable, there’s no air draft, … makes for a much nicer environment overall Laurent Clerc, VP of Information Technology Copyright 2012 - Green Revolution Cooling
