ROCKVILLE, Md. & AMHERST, N.Y.--(BUSINESS WIRE)--March 20, 2002

OTG Software (NASDAQ: OTGS), a global provider of next-generation enterprise data management software, and ATTO Technology, Inc., a worldwide manufacturer of Fibre Channel and SCSI storage-infrastructure solutions for Enterprise and Content Creation environments, announced today that the ATTO FibreBridge(TM) 3200R has been certified for use with OTG's DiskXtender(R) and SANXtender(TM). Certification of the ATTO FibreBridge 3200R is a demonstration of companies partnering to deliver scalable, interoperable and cost-effective storage solutions, and enables OTG to help IT administrators better leverage their existing storage-infrastructure investments.

ATTO's 1-Gig FibreBridge 3200R Fibre Channel-to-SCSI bridge boasts full software support, including interchangeable LVD and HVD tape personality modules, serverless backup and intelligent Bridging Architecture(TM), making it ideal for Enterprise-level storage applications requiring 1-Gig throughput. Accessing and backing up existing SCSI storage is maximized through ATTO's unique implementation of the SNIA 143r1 specification. Extended Copy commands received by the FB 3200R are re-sorted and executed to achieve constant data flow to the attached SCSI tape drives. The advantage of ATTO's implementation is the prevention of "shoe shining" - where tapes have to rewind and restart as a result of interrupted data flow advancing the wear and tear on tape drives.

OTG's flagship solution for enterprise data-storage management is DiskXtender. Central to DiskXtender's core capabilities is its "infinite disk" virtualization technology. This technology expands primary and/or secondary storage onto any number of additional devices or media types, optimizing capacity while giving end users open access to all of their data regardless of where it is stored. SANXtender provides transparent application access to data on the SAN. Serverless data movement within the SAN is easy to achieve when configured with an ATTO FibreBridge 3200R and OTG's SANXtender.

"Our FibreBridge 3200R, when used in conjunction with OTG's SANXtender and DiskXtender, enables high performance serverless backup and data access to and from various optical devices such as CD, DVD or MO drives," states ATTO President and CEO Tim Klein. "Continued certification of ATTO products with leading software vendors such as OTG is in alignment with our strategic philosophy of developing industry-wide, interoperable, storage-infrastructure components."

"Interoperability in SAN environments is a critical customer need," said William Caple, Executive Vice President of OTG Software. "Certifying our software solutions with leading infrastructure providers such as ATTO helps us meet customer demands for scalable, interoperable storage solutions."
