Data Domain Granted Patent for Ultra-High Performance Capacity Optimization Technology

Invention to Enable 20x Data Compression to Achieve Typical Disk File System Throughput at Tape Library Cost

PALO ALTO, CA -- (MARKET WIRE) -- August 22, 2005 -- Data Domain, the leading provider of Capacity Optimized Storage (COS) solutions, today announced that the U.S. Patent and Trademark Office has granted Data Domain Patent Number 6,928,526 entitled, "Efficient Data Storage System." This patent covers the technology critical for capacity optimization of data storage on disk, which enables COS systems to replace tape libraries and offer disk-based speeds, cost-efficient replication and higher reliability.

The new patent highlights the approaches used in the Data Domain DD400 Enterprise Series products for minimizing the use of RAM, disk I/O and processor cycles to identify unique data segments and store them efficiently for backup/restore applications. Using these methods, Data Domain remains the only vendor to be shipping a COS appliance that can support standard backup software for less than $1/GB while supporting up to 290 GB/hour throughput.

"Data Domain delivers the fastest capacity optimized storage systems in industry standard backup environments by a wide margin," said Frank Slootman, president and CEO of Data Domain. "The invention highlights the combination of unprecedented efficiency delivered at unparalleled levels of throughput."

Data Domain has ten additional patents pending in the area of capacity optimization. In recent years Data Domain invented several key technologies to identify and remove redundant data segments at high speed. With Data Domain's innovations, such systems can perform at high throughput and also enable end-to-end data integrity and recoverability verification at backup time. The patent's inventors are Data Domain Senior Architect and co-founder Ben Zhu, Chief Architect Dr. Hugo Patterson, and Chief Scientist and co-founder Dr. Kai Li who is also a Charles Fitzmorris Professor at Princeton University.
