Qualstar Develops a Prototype Enterprise Class Library Solution with Sony Imaging Products & Solutions Inc.

Qualstar Corporation (NASDAQ: QBAK), a leading provider of data storage systems, has developed a prototype enterprise class library solution with Sony Imaging Products & Solutions Inc. ("Sony"), which will be displayed at Sony's booth (#795) during the upcoming SC19 conference and exhibition in Denver.

The highly scalable enterprise class library solution leverages Qualstar's expertise and experience in designing efficient robotic-based storage systems. Utilizing Sony's Optical Disc Archive Generation 3 technology, a single library will scale from 4.7 PB up to 50 PB.* It can scale out to multi-library cluster configurations capable of managing hundreds of petabytes of archive data.

"Today's supercomputing environments need high capacity, scalable data storage solutions to archive data for a longer period of time," said Arun Vaishampayan, Qualstar's Vice President of Global Sales. "Sony's Optical Disc Archive Generation 3 storage platform fulfills the needed requirements of this market."

"We are delighted with the progress of this project," said Steven N. Bronson, CEO of Qualstar. "We believe the jointly developed product will serve the needs of our valued customers and open new markets for optical devices."

*Recording capacity depends on the usage environment. Actual recordable capacity may be less than indicated on the cartridge.
