- 4. • Reduce energy usage • Create more efficient rack space Cooling Solutions The Aim The government will be introducing a carbon tax in 2009 All companies will have to report power usage by law
- 5. Recent studies reveal that data centre power densities have increased ten-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 Source HP Industry Studies
- 7. 38-42 o C 32 o C 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 Cooling Solutions 49.6 l/s/kW (223.2 l/s @ 4.5kW) Typical 7U Blade Server 22 o C Typical 1U Server 75.5 l/s/kW 22 o C
- 8. 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. Existing Configurations Room Based Cooling

- Fact 1: Power and cooling costs increasingly limit scalability of your data center, and consume an ever-larger share of budget resources. The 3-year energy cost of highly dense servers is roughly equivalent to their acquisition cost. 1 Fact 2: Advances in compute density, such as blade servers, have resulted in highly dense servers that require significantly more power and cooling than traditional server configurations. Industry analyst Gartner wrote, “The leading server vendors recognize the problems associated with highly dense hardware and, in particular, with the rapid uptake of high-density blades. As such, they are attempting to develop solutions to deal with those problems.” 2 Fact 3: The power and associated costs to cool the datacenter can be as much or more than the cost of powering the IT equipment (servers, storage, and networking). [3] A study by HP and The Uptime Institute suggests that in a majority of the world's data centers 63% of a datacenter’s power is associated with the power of cooling the IT equipment. 4 While the rest of the industry is narrowly focused on only one aspect of the problem -- reducing the power of chips and other components, HP is also addressing the need to reduce the power requirements and costs associated with cooling the datacenters themselves. Fact 4: Reducing the energy required to cool a datacenter can result in significant cost savings (and reduction in CO2 emissions) or the ability to deploy more IT equipment in the same space -- or a mixture of the two.
- Why The onset of high density computing including blades
- Blade servers both offer increased computing density and a significant performance per watt benefit. These inherent advantages of blades when matched with advanced power and cooling infrastructure, can assist to drive out waste in the physical environment and drive up efficiencies.
- Major obstacle is the length scale of air delivery - distance between cooling units and heat load make it difficult to properly remove the heat generated from IT equipment without mixing with supply air - results in hot spots and a complicated design approach to air distribution
