The Netezza Performance Server (NPS) analytic appliance redefines energy efficiency in data warehousing, while providing cost-effective query performance beyond the reach of other systems. This paper examines the power crisis in the data center, and the environmental impact of general-purpose processor technology (web servers, email servers, OLTP servers, etc.). Today's tightly packed servers consume more power and give off more heat than their predecessors as the latest generations of x86 chips drive enormous amounts of data through microscopic circuitry. But is this type of computing, and the power it requires, optimal for data warehousing? The paper then examines the NPS system from an energy efficiency perspective.
