Luminex Joins the StorageTek TekAlliance Partner Program

StorageTek FlexLine Customers Now Have Mainframe DASD Connectivity Option

Riverside, Calif. - April 27, 2005 Luminex™ Software, Inc., a leading developer of mainframe connectivity products, and StorageTek® (Storage Technology Corporation, NYSE: STK), the leading provider of enterprise information lifecycle management, today announced Luminex's Virtual|BLUE™ 3990 control unit has been certified interoperable with StorageTek FlexLine™ online storage systems for native mainframe direct access storage device (DASD) connectivity. As a result, Luminex has become a new member of the StorageTek TekAlliance™ Partner Program.

Together, Virtual|BLUE 3990 and FlexLine online storage systems offer StorageTek's mainframe customers cost-effective options to vastly increase the capacity of their tier two mainframe DASD data storage. In addition, the combined products increase the simplicity and capabilities for remote replication and disaster recovery configurations for mainframe DASD. DASD costs are dramatically improved and proprietary mainframe channel extension and data replication costs can be cut. In their place, standard networking protocols and StorageTek's open systems data management tools can be deployed.

"I am encouraged by our strong and growing partnership with StorageTek to meet the ongoing data management needs of mainframe customers," said Arthur Tolsma, CEO of Luminex. "Our products naturally complement each other for the ultimate benefit of the customer by cost-effectively providing more features, capabilities, and choices than traditional mainframe DASD solutions."

"Through our alliance with Luminex, our customers no longer need to look beyond StorageTek to meet their growing needs for tier two mainframe DASD storage as part of their information lifecycle management solution," said Cameron van Orman, StorageTek director of Corporate Alliances at StorageTek. "This combination will be particularly noteworthy for mainframe customers seeking a way to increase the productivity of their primary storage assets."

Luminex's Virtual|BLUE 3990 is the first disk independent control unit that enables open systems disk storage for use as native DASD on mainframes. Each Virtual|BLUE 3990 control unit supports up to 1024 DASD volumes configured as 3380/3390 -3, -9, -27. -54 devices, providing more than 50TB of storage capacity. The Virtual|BLUE 3990 control unit effectively eliminates the proprietary boundaries and vendor lock-in that separate the mainframe and open systems storage worlds, enabling mainframe enterprises to take advantage of the ever-increasing features and ROI benefits being delivered by the disk storage industry.

StorageTek's TekAlliance program offers mutual customers a wide portfolio of jointly sold and supported storage solutions to better meet their specific information lifecycle management and storage needs.
