ONSTOR EXPANDS LINE OF PANTERA VIRTUALIZED STORAGE SOLUTIONS, SETTING NEW STANDARDS FOR SCALABILITY AND EFFICIENCY

New Pantera 5000 Delivers Massive Clustered NAS Scalability with Low Energy Consumption for Medium to Large Enterprise Environments and Digital Imaging Applications

CAMPBELL, Calif.- Sept. 25, 2007 – ONStor Inc., the leading provider of scalable clustered NAS solutions for the enterprise, today announced a new addition to its Pantera line of virtualized storage solutions with the launch of the Pantera 5000. A fortified version of its clustered NAS solution, the Pantera 5000 more than doubles the per cabinet capacity of the Pantera 2000 and offers higher performance to support the large, fast-growing file storage demands of medium to large enterprises and organizations with substantial digital imaging storage requirements. ONStor's newest product offers storage managers advanced power management; the ability to scale to massive capacities at a greater density; plus file server consolidation features to deliver a greener data center solution via low energy consumption, a reduced footprint, and lower cooling costs.

"ONStor has emerged as a thought leader in the green file storage arena," said Steve Norall, senior analyst, Taneja Group. "With the release of Pantera 5000, ONStor continues to push the envelope by delivering a denser, more scalable NAS solution with an industry-leading power and cooling footprint."

The ONStor product line, which includes the new Pantera 5000, the Pantera 2000 Series Clustered NAS, and the Bobcat NAS Gateway, offers enterprise customers a range of scalable NAS solutions designed to minimize the cost and administrative burden of managing data growth in real time across multiple tiers of storage.

Massive NAS Scalability, High Performance
The Pantera 5000 supports up to 112 drives per RAID controller and can scale up to 672 terabytes across eight nodes. With ONStor's global namespace (GNS) technology, customers can easily grow their networked storage environment while keeping storage provisioning and management simple. Furthermore, the Pantera 5000's open storage design accommodates heterogeneous storage and supports more than 40 enterprise storage arrays, enabling organizations to protect their investment by leveraging their existing storage devices. These capabilities eliminate the obsolescence and complexity common with traditional NAS solutions in high data growth environments.

"With persistent data growing faster than any other class of data, we designed the Pantera 5000 to meet customers' rising demand for very high-capacity storage that is cost-effective and easy to manage," said Bob Miller, CEO, ONStor. "We will aggressively be introducing 1 terabyte drives as they become available, to continually push the envelope of how much data companies can store while maintaining a simple, unified management scheme across multiple tiers of file storage."

The Pantera 5000 is particularly attractive to medium and large enterprises with growing amounts of tiered data that need to be online and available 24/7. In addition, companies focused on geo-spatial mapping, satellite and medical imaging, seismic data, and online images will find the Pantera 5000 a very scalable and economical solution for storing, managing and protecting their data.

"Before ONStor, managing storage in an organization handling huge files like ours would quickly start to take on a life of its own. With the extremely scalable Pantera 5000 solution in place, our data center operations are smoother than ever. We no longer worry about running out of capacity or the downtime consequences of having to add more storage," declared John Welter, vice president of technology, Northwest Geomatics. "It's all automated and managed with point-and-click ease."

Advantages of Pantera 5000 Scalable Clustered NAS
With the Pantera 5000, users can now deploy a scalable solution for tier 1 and tier 2 storage within same cabinet, because the Pantera 5000 supports Fibre Channel for tier 1 fast-access storage and SATA for tier 2 nearline applications. In addition, the Pantera 5000 provides:

• Massive scalability, up to 672TB
• True open, clustered NAS
• N-way clustering with support for up to eight nodes across heterogeneous ONStor models
• Up to 2.75GB/s of sustained performance
• Integrated file server virtualization, global namespace (file virtualization), remote replication, and native file management protocols (CIFS, NFS)
• RAID 6 available in Q4 for very high availability

"The ONStor Pantera 5000 is a shining example of the outstanding price/performance benefits that can be achieved by combining state-of-the-art clustered NAS technology from ONStor with enterprise-proven storage solutions from LSI," said Steve Gardner, director, product marketing, LSI. "LSI is committed to working with ONStor to deliver leading-edge networked storage solutions that offer customers the highest degrees of scalability and performance in an energy-efficient form factor."

The Pantera 5000 is available today from ONStor and its partners in the United States, Europe, and Japan at a list price of $125,000 for a two-node cluster with 24 terabytes of nearline storage. ONStor systems are deployed across a wide range of demanding enterprise IT applications, including large-scale Windows server consolidation, Internet content delivery, and digital imaging.
