REDMOND, Wash.--(BUSINESS WIRE)--April 24, 2002

Advanced Digital Information Corporation (Nasdaq:ADIC), the leader in Intelligent Storage solutions, announced today that EMC Corporation (NYSE:EMC), the world leader in information storage, has qualified the ADIC Pathlight 5000 connectivity and management appliance as E-Lab Tested(TM).

E-Lab Tested qualification means that the Pathlight 5000 has passed a comprehensive suite of interoperability tests in EMC storage system environments. The qualification established by the E-Lab Tested program allows end users to confidently deploy heterogeneous storage networks quickly, reliably and cost effectively. The Pathlight 5000 is also included under a cooperative support agreement (CSA) between the companies, which provides coordinated pre- and post-installation support services for the company's joint customers.

"EMC's E-Lab qualification of the ADIC Pathlight 5000 connectivity and management appliance adds an important new platform for getting more functionality from storage network environments," said Chuck Hollis, Vice President of Markets and Products at EMC. "The EMC E-Lab Tested program is a rigorous program dedicated to making certain that our customers can build multi-vendor SANs that deliver the full promise of storage networking technology, and that provide high performance, reliability, and ease of installation and management. We are pleased to add the Pathlight 5000 to that qualified solution set."

"EMC's E-Lab Tested program has become one of the key industry benchmarks for establishing broad interoperability. We are pleased to have qualification for the new Pathlight 5000 at its launch, and to be the first 2 Gb connectivity appliance to be qualified," said Bill Britts, ADIC Executive Vice President of Sales and Marketing. "The Pathlight 5000 capabilities, by providing a flexible, managed link between compute and storage resources, is helping SAN architects expand the range of uses for storage networking environments."

EMC assures customers the highest level of interoperability assurance with its comprehensive testing. In EMC's E-Labs, engineers replicate customer environments--using 2,600 terabytes of storage across nearly five acres of floor space. To date, EMC has tested nearly 400 server types, 40 operating systems, 81 third-party storage software products, 145 network connectivity elements, and 1,200 different devices ranging from HBAs and drivers to switches and tape subsystems.

The Pathlight 5000 enables a wide variety of storage network devices, including servers, NAS filers, disk and tape systems, to operate together within a managed environment. It connects devices that use different protocols, lets dissimilar operating systems share the same SAN, provides dynamic mapping between servers and disk volumes, and controls access to storage resources within a SAN to provide full security. IT architects use the Pathlight 5000 to combine heterogeneous devices into a single, centrally managed environment in order to obtain the highest possible value and utility from their data center resources.
