NetApp® Deduplication Technology Helps Polysius Reduce Data by 47%

Sunnyvale, Calif. - October 2, 2007 -- Network Appliance, Inc. (NASDAQ: NTAP), a leading provider of storage and data management solutions, today announced that Polysius, a leader in the cement and mineral industry with experience in the design, supply, and installation of cement plants and process equipment, reduced redundant data by a dramatic 47% in just over one month after adding NetApp A-SIS (advanced single-instance storage) deduplication technology into its storage environment. In just four months, NetApp customers have enabled A-SIS deduplication on over 10PB of raw storage.

For more than 140 years, Polysius has prided itself on its use of innovation for both engineering and technical achievements. Because Polysius is an innovator in its field, it came as no surprise that deduplication was at the top of the priority list for Polysius's manager of IT, James Krochmal, as a means to dramatically maximize existing resources-money, management, and time-while simplifying the management of its storage infrastructure.

"Polysius was duplicating data like crazy as a result of the fact that we consistently replicate all of our CIFS file shares," said Krochmal. "These countless copies of data files were consuming vast amounts of our storage. NetApp deduplication technology enabled us to more efficiently store our data and deduplicate all of our primary user data with absolutely no performance hit."

In May, NetApp became the first major storage vendor to offer customers the cost benefits of deduplication across a wide variety of environments, including backup, archival, and primary data sets and applications as diverse as home directories and genomic data (see related announcement at NetApp deduplication technology provides customers the ability to reduce capital expenditures and management costs by dramatically reducing the amount of storage they need to purchase and manage. By eliminating duplicate data and freeing up storage capacity, enterprises can also reduce the need to add more physical storage and dramatically lower the space, cooling, and power needed in their data center.

Krochmal continued, "The reduction in the quantity of our physical storage translated into tremendous cost savings in our data center. NetApp deduplication technology freed up budget that was going to be spent on more spindles that will now be spent on new technologies that will move our business-and our customers' businesses-forward."

"Deduplication helps our customers save money," said Patrick Rogers, vice president of Solutions Marketing at NetApp. "Polysius is a prime example of how deduplicating redundant data has a multiplicative effect in reducing capital equipment, administrative, facility, and energy costs. This is why our deduplication technology is rapidly spreading within our enterprise accounts in a variety of applications, including backup, archival, and primary data storage."
