 Latest RAID Development by Ultera Leverages Performance of
Sony AIT and Qualstar Tape Library System

Laguna Hills, CA - May 11, 1999 - Ultera Systems, the leading tape array controller company, today introduced its most advanced product LibraryMasterÔ, which is specifically designed to integrate with tape libraries.

Driving five tape drives in parallel, the new Ultera RAID controller reads and writes data at four times the speed of conventional subsystems, while providing guaranteed data recoverability in the event of a damaged or lost tape media.

 "This is a reality now," said Fred Bedard, Ultera Vice President of Sales and Marketing. "Backup applications can take advantage of faster processors, I/O and tape drives, and leverage the performance of their existing backup software to a new level."

Guaranteed Data Recoverability
By allowing the output from the host system to write to four drives in parallel and using the fifth drive to generate parity code, data retrieval is guaranteed. Should a tape cartridge be lost or damaged, LibraryMaster will automatically rebuild lost data by drawing from the remaining tapes.

Enhances Sony and Qualstar Systems
Interfaced with Sony’s Advanced Intelligent Tape (AIT) drives, and Qualstar’s TLS-4000 Tape Library, Ultera’s new technology enhances AIT automation capabilities. "The solution provided through the LibraryMaster with Sony AIT drives and Qualstar’s scalable library systems is absolutely on target with the demands we have been seeing for mid-to-high-end enterprise backup applications in providing new levels of performance and data integrity," said John Woelbern, Senior Marketing Product Manager for Sony’s Tape Streamer Products Division. "By utilizing Sony’s new AIT-2 tape technology, for example, this solution can now provide an astounding native data transfer rate of over 40 megabytes per second, assuming 2.0:1 data compression.."
Qualstar Vice President of Sales Bob Covey said that LibraryMaster is a technology complimentary to the Qualstar’s library line. "Our libraries are recognized for their reliability and advanced design characteristics. Ultera’s LibraryMaster enhances the performance of our system as well as providing expanded security through its unique data recoverability."

Compatibility With Existing Systems
LibraryMaster requires no additional software and is totally compatible with all leading backup software and storage management packages and operating systems, including Windows NT, UNIX, and Mac OS. It supports ultra, fast, and wide SCSI, with either single-ended or differential interface. LibraryMaster is currently shipped as a 19" rack-mount configuration with LCD control panel. Manufacturers’ suggested retail price is $14,550.
