Cooling Solutions to meet the
Higher Density Requirements
 Requires moving the cooling closer to the heat source to;
   – more precisely cool the specific load
   – not waste energy - “brute force” by cooling the whole room.

 Cooling coils may be in multiple locations;
   – External to the Rack – Overhead, Back, Side
   – In the Rack – Under, Side
   – Part of the Server

 Requires a fluid to be delivered to the cooling coils to transport
  the heat out of the Data Centre. Can be;
   – Chilled Water (ChW)
   – Refrigerant (pumped low pressure)

 Cooling closer to the source of the heat    Less Power (energy
  makes the heat exchangers more efficient     consumed)

Summary
 Cooling solutions for higher density will need to move
  closer to the load and will require a reliable fluid delivery
  means
   – Cost effective cooling solutions exist that can be
     employed today that meet future needs
   – Allow racks to be fully populated

 Cooling at the source of the heat load will actually lower
  your incremental energy consumption
   – Less power for the cooling system provides more
     power for the IT equipment


Which leads to a significantly reduced TCO.
