Data Domain and Luminex Partner to Address Mainframe
Users' Data Protection Needs

Vendors Enable Deduplication of Mainframe Data for Tape-free Disk Backup and Network-based Disaster Recovery

SANTA CLARA, Calif. and RIVERSIDE, Calif. — April 18, 2007—Data Domain, a leading provider of Enterprise Protection Storage systems for disk backup and network-based disaster recovery, and Luminex Software, a leading developer of mainframe connectivity, channel gateway, storage and data distribution products, today announced that they have partnered to deliver solutions that allow mainframe users to reap the benefits of data deduplication for tape-free, disk-based backup and WAN vaulting of backup data for DR. By combining Data Domain appliances with Luminex's Channel Gateway products, mainframe users can reduce or eliminate their reliance on tape systems and implement advanced data protection processes.

Luminex Channel Gateways enable FICON and ESCON mainframe protocol and virtual tape connectivity to open systems Ethernet and Fibre Channel storage systems. Data Domain's enterprise protection storage systems use Ethernet or Fibre Channel to connect into the IT infrastructure. Shoden Data Systems has successfully integrated the vendors' solutions and deployed a mainframe environment data protection solution for a leading retail company in the Republic of South Africa.

"The combination of Luminex and Data Domain technologies opens the door for mainframe users to deploy tape-free data protection solutions in their environments and realize the benefits of data deduplication technology," said Mark Slade, director of business development for Shoden Data Systems. "Our client was able to eliminate a tape-based backup and disaster recovery solution that was extremely costly and time consuming to manage. The Luminex/Data Domain solution was much faster, highly reliable and simple to install, and our client no longer has exposure to the inherent risks associated with physical removal of tapes for offsite storage."

"Mainframe users have not had access to some of the latest backup and recovery technologies that were designed for open system environments," said Tom Trainer, Senior Analyst for The Evaluator Group. "The pairing of Data Domain and Luminex gives these users access to data deduplication technology, disk-based backup and network vaulting of backup data for DR purposes. This solution illustrates that mainframe users have more data protection options and are not limited to just tape-based systems."

Shoden Data Systems' client in South Africa is currently protecting 9 terabytes of data with its Data Domain/Luminex solution. A Luminex Channel Gateway is used to establish connectivity with the mainframe and present backup data to a Data Domain DD560g Gateway, which deduplicates the data and stores it to a Hitachi Data Systems Fibre Channel disk array acting as the local backup storage target. Data Domain's Replicator software is used to replicate the backup data to a Data Domain DD560 appliance in a remote location for disaster recovery purposes. Data Domain's Global CompressionTM technology ensures network-efficient bandwidth use by only replicating data that does not already reside at the remote site.

Brian Biles, Data Domain's vice president of product management, said, "Luminex already has a strong pedigree in the mainframe connectivity market, so we felt confident that their storage networking technologies would allow us to make leading data protection solutions available to mainframe users. We believe that this effort between Luminex and Data Domain is good news for mainframe users."

"By partnering with Data Domain, Luminex's objective of providing transparent mainframe connectivity with open systems-based storage networking technologies has taken yet another step forward-this time in the interests of bringing new and exciting data protection capabilities to mainframe data centers. Data Domain's enterprise protection storage solutions carry an exceptional value proposition and we're pleased to be partnering with them to now make these solutions available for mainframe customers," said Luminex president Michael Saunders.
