Server heat densities hit a wall – CNA’s bring relief
Posted by David Vellante in Wikibon on October 20th, 2009
Server designers face enormous challenges in the coming decade. Huge increases in processing power combined with the effects of virtualization are constraining server real estate and testing heat density limits. These issues are even more pronounced in very high performance system environments.
By 2008, high-end blade servers had already reached 10kWatts/sq. ft. in heat density, and the historical increase of 30% per year in heat density for servers is holding steady. If these trends continue, the operational costs associated with space, power and cooling for most servers will exceed the acquisition costs over the life of the equipment.
Server manufacturers are using several approaches to reduce heat density, including:
Wikibon Peer Incite to Feature NetApp’s Internal Focus on Green IT
On August 25th Dave Robbins, CTO, IT Infrastructure at NetApp will be discussing how they have transformed their IT operations from a legacy of inefficient and costly practices to its current level of enviable data center efficiency illustrated by a predicted PUE of 1.2 in their latest data center.
Dave’s discussion will be shaped by the accomplishments of his team over the past couple of years and to give some insight into the upcoming session the following are some of the team’s achievements.
By implementing VMware they reduced x86 based clients from 4600 to 230 saving $1.3M in power and cooling and reducing the number of racks needed by 182.
How Cap and Trade legislation could impact data center budgets.
Recently the President put as all on notice that a Cap and Trade policy is likely to become a reality in 2009.
For those who are unfamiliar with the term Cap and Trade it is an environmental policy designed with the intent of reducing undesired emissions by mandating emission levels and establishing caps and in the words of the eloquent bureaucrat it provides environmental accountability without inhibiting growth and rewards innovation, efficiency and early action. Please excuse my skepticism.
