2. … the story so far In the beginning power dissipation
levels in Cabinets were low ……………….
With the advent of rack mount servers, the power dissipations increased ………..
Now, with use of 1U Servers becoming
widespread, these levels are set to cross.
Floor space in Data Centres is expensive.
The trend is to pack as many servers in
one cabinet as possible
But conventional cooling methods are inadequate when the “ceiling” is reached
4. General Cooling Methods
5. Todays high performance Rack-Mount Servers consume as much as 300 Watts of power in a 1U high format. This power is dissipated as heat within the cabinet
6. Internal view showing devices with heat sinks for conduction and DC fans set up to create strong air currents from the front of the equipment towards the rear.
8. In general, professional grade equipment have adequate cooling provisions designed into them so that they are able perform normally to their published specifications given the required ambient conditions……. provided those required ambient conditions are maintained unimpaired. Equipment stacked inside a Cabinet encounter a very different environment from the free- standing equipment in an air-conditioned room.
9. Conventional cooling methods for computer equipment in cabinets … generally adopted arrangements
12. The type of arrangements for cooling of equipment inside
cabinets just seen is the conventional approach. These worked fine till now when heat loads were fairly light. But these methods have severe limitations in todays situation.
Conventional cooling methods are 30 years old
Conventional designs compromise equipment reliability
Conventional cooling systems are expensive to build
Conventional design is expensive to operate
13. In many Computer Centres it is common to have the AC Inlet and Return ducts running along the top of the room. This results in airflow patterns that are far from ideal for the equipment inside the Cabinets.
14. The newer computer facilities may have both false ceilings and raised plenums with the inlet AC ducts below the raised floors while the return air ducts are above. This leads to more effective equipment cooling
15. Same room showing cabinets positioned over the AC inlet
18. How does the CoolRack concept work ?
21. CoolRack – an internal view
23. Same views - but showing airflow arrangements
