IRVINE, Calif.--(BUSINESS WIRE)--Aug. 26, 1999--

ATL Products, a Quantum Company (NYSE:DSS) and leading supplier of intelligent DLTtape(TM) libraries for networked computers, Thursday announced that it has become a founding member of Legato Systems' Celestra Consortium.

The new organization, founded by Legato Systems, provides an industry forum for all member participants to help develop standards and interoperability that will make data movement and management of Storage Area Network (SAN) environments more effective using the open and integrated Celestra architecture. Jointly participating in the consortium with leading storage automation companies, ATL plans to be actively involved in helping to meet the organization's objectives.

The purpose of the consortium is to create an industry-wide forum consisting of leading manufacturers to advance LAN-free, serverless backup SAN applications. From this ongoing exchange of information between vendors, the consortium will identify, define, promote and support specifications, standards and infrastructures that will enable consistency and interoperability for SAN solutions based on Celestra open architecture.

To assist members in developing robust, interoperable solutions to the market quickly and more efficiently, Legato Systems will provide consortium members with development kits, certification and marketing support programs.

ATL Products was one of the first secondary storage providers to embrace the Celestra serverless backup capability and the hardware/ software combination offers real-time backup, without host intervention, at speeds ranging up to one terabyte per hour.

"ATL's commitment to developing open, integrated SAN solutions utilizing the Celestra technology, is a big win for customers," said Paul JJ Payack, vice president of worldwide marketing, Legato Systems. "With ATL's expertise in the library storage market, we are pleased to have them on the team."

"ATL has joined the Consortium because of the many benefits that Celestra promises our customers including continuous, high-performance, 24x7 accessibility of enterprise applications with fail-safe data protection that eliminates the need for backup windows," said Frank Berry, vice president of marketing for ATL Products.

"The Celestra Consortium is an outstanding next step in providing developers, like ATL, with the tools and support for creating more robust LAN-free, serverless backup solutions."

About Legato Celestra

Legato's Celestra introduced an open, distributed architecture that optimizes data movement efficiency in SAN environments. Data movement is performed by an intelligent SAN device that complies with the open standard SCSI Extended Copy specification. Data movement intelligence is provided by Legato Celestra agents, enabling powerful applications such as serverless, outboard backup that eliminates the backup window.

Control is provided by Network Data Management Protocol (NDMP)-compliant control applications such as Legato NetWorker. This open standards approach means maximum customer ROI and operational efficiency.
