Power and Cooling Feature Story
| Annual Power Consumption
Lets say that for a particular transaction intensive application operating at a certain service level in your data center you require 100 Dual Opteron or Xeon Servers. The average power consumption of this class of systems is roughly 300-400 watts each, with an additional 60% of power² required to cool these systems to normal operation temperatures.
That's an annual power consumption of between 42-56 mW·h, and assuming a conservative electricity charges in your area of approximately $.10 per kW·h³, that is an annual energy bill between $42,000 and $56,000. Interestingly enough, with an annual power and cooling cost of between $420 and $560 per server per year, over the 3-year useful life of your server, you could have nearly spent more on electricity than the initial cost of your commodity server! As system prices continue to drop and energy prices continue to increase, this picture will only get more unpalatable. According to the U.S. Department of Energy, energy prices have risen approximately 7% CAGR over the past fifteen years, and the current forecast is for comparable increases. Less is Definitely More Less electricity and less heat generated by Azul compute appliances can provide a sharp reduction in data center power and cooling requirements, sometimes by as much as 50% even as throughput is increased and service levels are maintained. In fact, a recent customer saw a boost in application throughput from 1,500 operations per second to over 10,000 operations per second providing ample capacity to support the growing user base. At the same time, power requirements decreased from 30 kW to less than 15 kW. And with fewer servers, the data center now provides better service levels while having spare foot print and power/cooling capacity, ready for new innovative applications that will ignite new revenue opportunities.

See for example:
³Electricity charges of $.10 per kW·h are very conservative. Depending on the metropolitan area ( New York, Bay Area), and the seasonal uplift for Summer, could easily reach of $.17 per kW·h. See for example:
