Energy costs are rising
The cost to power and cool server room equipment
now exceeds the purchase cost on a 3-year life-cycle, based on a traditional server room / data centre configuration.
The government will be introducing a carbon tax in 2009
All companies will have to report power usage by law
Recent studies reveal that data centre power densities have increasedten-fold in the last 10 years
and that cooling represents upwards of 60-70% of the total data centre power spend for the majority of customers. These costs are driven by the data centre power requirements and the volume of cooling airflow required
What are the cooling challenges in today’s data centres?
(223.2 l/s @ 4.5kW)
Typical7U Blade Server
It is not only direction of airflow that must be taken into consideration, but also
temperature rise across the server and the air volume required by the server fans.
Blade servers are the most electrically efficient form of server. Available blade types for a
given blade server system can vary dramatically in performance and power consumption
Room Based Cooling
The predominant architecture for cooling data centres since the inception of the mainframe has been raised floor air delivery from perimeter computer room air conditioners (CRAC).
At lower densities (1 – 5 kW / rack), adequate cooling is provided to IT equipment, despite the mixing of air throughout the room.
Row Based Cooling
Note: In-row cooling architecture, as depicted, utilises a free air discharge without ducting or any containment of hot or cold air streams.
