Framingham, Mass. – August 20, 2007 – Netezza Corporation (NYSE Arca: NZ), the global data warehouse appliance market leader, today announced the latest release of its Netezza Performance Server® (NPS®) system that will give customers twice the performance through a software enhancement that runs on all generations of Netezza systems, with no increase in price, hardware footprint or power and cooling requirements. With Release 4 of the Netezza appliance, enterprises can now broaden the types and complexity of workloads, and handle larger numbers of concurrent queries and users, with faster performance and the same low total cost of ownership and ease of use.

Release 4 of the Netezza appliance improves system performance in extremely busy, enterprise-level data warehouse environments. For example, a broader range of tactical and operational queries can be completed in second or even sub-second time, while ad hoc and deeper, more advanced analyses running concurrently are completed in just seconds or minutes – all leveraging the high performance, affordability and ease of use of the NPS system. The high-speed bulk data movement capabilities of the Netezza system – up to two terabytes per hour – combined with integration with third-party tools, provide a fast and simple means of backing up and restoring large volumes of data to ensure business continuity in the enterprise.

Netezza partner MicroStrategy, a global leader in business intelligence (BI) and reporting technology, has seen significant performance gains with Netezza’s Release 4. According to Jeff Bedell, CTO of MicroStrategy, “Netezza has an established track record of delivering impressive query performance for complex reporting and ad hoc analytics against large datasets. In our internal testing of Release 4, we’ve seen multi-pass queries against smaller datasets run three times faster than they did in Release 3. Netezza’s improved query performance makes it even more compelling for our joint customers.”

The significant performance increase in Release 4 is due to several algorithmic optimizations across the NPS system. Since the first generation of NPS appliances, Netezza has placed processing power next to the data, so data analysis occurs at the source at streaming speeds, delivering an unprecedented boost in performance. Release 4 enhancements enable the system to make smarter decisions about the data required for a specific query and further limit movement of data irrelevant to the query, right at the source.

“Appliance vendors like Netezza that closely integrate system hardware and software are able to create quantifiable performance advantages because they control the whole technology environment,” said Dan Vesset, program vice president, business analytics, IDC. “This increased performance will enable more business users to derive deeper insights from more of their data in a timely way.”

Release 4’s enhanced query history and monitoring functionality also allows companies to monitor how queries are proceeding in the system and get “snapshots” of query history to observe behavior and workload conditions over time. This helps guide system expansion planning, resource management and decisions in the data warehouse.

“Netezza’s large and growing global customer base is constantly ‘pushing the envelope’ in terms of the broad range of analytics they run on our appliances. Our ongoing innovation and price/performance enhancements act as a catalyst for data-intensive companies to transform their business using the NPS system,” said Jim Baum, president and COO of Netezza. “Because Netezza’s appliance tightly integrates all the software and hardware technologies into one compact and power-efficient unit, we are able to innovate across multiple dimensions, enabling significant price/performance improvements beyond Moore’s Law advances.”

Netezza has a proven record in innovation, increasing performance dramatically over time while maintaining a low total cost of ownership. In 2006, Netezza doubled system performance across a broad range of workloads through innovations in hardware and software, while lowering pricing.
