COMPELLENT AND ONSTOR DELIVER INDUSTRY'S FIRST INTEGRATED SAN AND NAS SOLUTION WITH AUTOMATED TIERED STORAGE
Delivers 80 percent reduction in storage expenditures by automatically migrating inactive data to a lower-cost tier of storage

Minneapolis, MN and Campbell, CA – March 27, 2006 - Compellent Technologies, a provider of affordable and modular enterprise storage solutions, and ONStor, the leader in Enterprise NAS Gateways, today introduced the industry’s first integrated SAN and NAS solution with automated tiered storage capabilities. Through a partnership with ONStor, Compellent will deliver and support the market’s first integrated SAN and NAS product which dramatically reduces storage expenditures by transparently migrating data between storage tiers.

The Compellent/ONStor partnership unites the benefits of both block and file storage to deliver unlimited SAN capacity and NAS performance via a highly scalable architecture that easily expands with the addition of storage controllers, disk enclosures and NAS gateways. Compellent is the single point of contact and contract for this end-to-end solution, which ensures a unified experience for the customer.

“Combining Compellent and ONStor allows us to deliver shared data access to all users and platforms, and easily scale as our storage needs grow,” said Nick Poolos, systems development engineer at Fisher College of Business, The Ohio State University. “Now, whether it is block or file access, we can scale while containing costs and maintaining performance.”

Tiered Storage with Automatic Data Migration
Compellent’s integration of ONStor’s NAS Gateway to its storage area network (SAN) delivers scalable storage with transparent, data migration across multiple tiers—allowing users to achieve maximum storage ROI by ensuring that data is stored on the most cost-effective storage tier based on customer usage patterns and policies. This automated tiered storage capability eliminates the need for time-consuming data classification associated with typical Information Lifecycle Management (ILM) solutions because all data movement is based on frequency of access.

“Midmarket businesses require enterprise-class file and block services at an affordable price,” said Bruce Kornfeld, vice president of marketing for Compellent. “Compellent’s modular scalability and automated tiered storage capabilities combined with ONStor’s Bobcat NAS Gateway provides the ideal combination of performance and features to reduce IT expenditures.”

Clustered NAS for Scalability
ONStor's Bobcat Series of easy-to-deploy and simple-to-manage NAS Gateways consolidate enterprise-wide file services for Windows, UNIX and Linux clients and servers onto Fibre Channel attached, multi-vendor disk arrays. ONStor delivers the industry’s highest performance open NAS gateways with three times the price/performance of NetApp products and enterprise-class scalability to 40 petabytes of capacity and more than 10,000 users.

“ Enterprise customers have traditionally been forced to purchase and manage disparate pools of storage to utilize SAN and NAS technologies, and to engage multiple vendors for technical support,” said Jon Toor, vice president of marketing at ONStor. “The Compellent/ONStor partnership provides an elegant solution to the problem that directly addresses the customer’s issue of lowering the cost and complexity of their storage environment.”

The joint Compellent/ONStor solution is available immediately through Compellent’s international network of business partners. Pricing for an entry-level solution starts at $71,000 and includes Storage Center with 2 terabytes of storage and a Bobcat NAS Gateway.
