MTI Awarded Patent for Design that Protects Systems During Power Failures.

New Technology Provides Cache Memory Data Protection for

Enhanced Data Integrity

ANAHEIM, Calif., April 14 /PRNewswire/ -- MTI Technology Corp. (Nasdaq: MTIC) today announced it has strengthened its role as a leading designer of enterprise storage solutions with the addition of a new U.S. patent for a device that protects data integrity during power failures.

U.S. patent No. 5,748,874 has been awarded for an enhanced technology that requires a small amount of power to operate storage controllers during an unexpected interruption to system power. MTI engineers recognized that it takes far less power to complete certain write operations of cache memory to specific, reserved disk locations. The new technology takes advantage of this low-power condition to preserve data residing in cache memory, a temporary storage "holding bin" located between the computer processor and permanent disk storage.

A disk drive in a computer system is equipped with a power storage unit that operates the drive controller in the event of an unanticipated brownout or power failure. Once the controller is alerted to a power interruption, MTI's new technology helps by exploiting a residual amount of power to store vital cache memory contents to a reserved space on the disk drive. After power has been restored to the system, the controller can reload the contents of the reserved data to the cache memory, returning the system to its previous operating condition without data loss or corruption.

"MTI engineers continue to demonstrate their leadership in the enhancement and evolution of fault-tolerant storage system design," said Earl Pearlman, MTI president and CEO. "This new patent is representative of our work on the cutting edge of technology to provide our customers with products that can weather all forms of planned and unplanned operating conditions."

Since 1990, MTI has been granted 38 patents for storage technology developed by the company and its affiliates. The new claim adds to MTI's RAID and fault-tolerant technology patent portfolio, one of the largest in the industry.

MTI's mission is to be the premier provider of high-performance, cross-platform data storage management solutions for the enterprise. MTI integrates distributed data management software, a hierarchy of modular storage systems and on-site services to meet the mass storage needs of its customers. Headquartered in Anaheim, Calif., the company offers services and support from more than 40 offices in the U.S. and Europe.
