New Family of Data Warehouse and Analytics Appliances Once Again Resets Industry Price/Performance Benchmarks for Data-driven Intelligence

SAN DIEGO, Calif. — The Data Warehousing Institute (TDWI) Event — August 4, 2009 — Netezza Corporation (NYSE: NZ), the global leader in data warehouse and analytic appliances, today announced the Netezza TwinFin™ appliance, the first in a family of new blade server-based appliances. The TwinFin appliance scales to more than a petabyte of user data and delivers orders of magnitude better performance over competing solutions. The TwinFin appliance is priced at less than $20,000 per terabyte, resetting the bar on price-performance in the industry.

“Seven years ago, Netezza redefined the data warehouse market with a patented appliance that tightly integrated hardware, software and storage to deliver 10-100 times the performance at a fraction of the cost of traditional approaches,” said Jim Baum, president and CEO of Netezza. “While many larger, incumbent vendors have embraced elements of Netezza’s approach and improved their own price-performance, Netezza’s TwinFin appliance once again extends our clear leadership in this market, from a position of strength as a mature global vendor."

“With the volume of enterprise data exploding, uniting data continues to be paramount. This is why appliances remain popular even in this economy – the purchase of infrastructure in data warehousing continues to grow with few limitations,” said Donald Feinberg, vice president and distinguished analyst in Gartner Intelligence in the Information Infrastructure group.

Netezza’s TwinFin appliance consists of Netezza software running on a configuration of commercially available, industry standard blade servers. Netezza’s hallmark performance is achieved through its patented software streaming architecture and a set of database accelerator cards that are seamlessly integrated with the blade servers. The TwinFin appliance is the first in a family of four appliances that will also include an entry level system, a high capacity system, and a memory-intensive system that will enable a new generation of real-time analytic applications. Details of these appliances will be announced at the upcoming Enzee Universe 2009 World Tour, which begins September 2 in Boston, Massachusetts.

“Netezza was an early entrant into this market category and this new appliance demonstrates the continued innovation we’ve come to expect from them,” said Steve Hirsch, chief data officer, SVP Global Data Services at NYSE Euronext. “With the advancements in the architecture of this new platform, we anticipate the new appliance will provide performance and scalability required to fulfill our data management growth strategy.”

The Netezza TwinFin appliance is available immediately, and the Company already has systems in production with customers.
