Netezza Doubles Performance for Enterprise-Class Appliances Through Software Enhancement

Netezza Corporation (NYSE Arca: NZ), the global data warehouse
appliance market leader, today announced the latest release of its
Netezza Performance Server(R) (NPS(R)) 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. To read more, please visit:

Availability

Release 4 of the NPS system will be available for all Netezza
customers in late August 2007.

The Netezza Performance Server system is built specifically to
analyze terabytes of detailed data significantly faster than existing
data warehouse options, at a much lower total cost of ownership. The
NPS system stores, filters and processes terabytes of records within a
single unit, analyzing only the relevant information for each query.
Netezza has placed the CPU power next to the data, allowing the NPS
system to speed through processes that would occupy most data
warehouse systems for hours, or even days, thereby enabling dramatic
increases in productivity across the organization.

Customers who have recognized the benefits of Netezza's approach
include Ahold, Amazon.com, CNET Networks, Debenhams, Department of
Veterans Affairs, Epsilon, Neiman Marcus, Orange UK, Ross Stores,
Ryder System, Inc., The Carphone Warehouse and Virgin Media.
