ADIC Helps Customers Preserve Long Term Data with Upgrade to Archiving Software; Provides Testing, Migration of Files to Preserve Data over Time.

REDMOND, Wash. -- Advanced Digital Information Corporation (NASDAQ:ADIC), the leader in Intelligent Storage(TM) solutions for the open system market, announced today the availability of the 5.5 release of its AMASS archiving software, designed to enhance users' ability to manage large-scale file-based data sets over extended time periods. The new capabilities include mixed media support that allows users to manage data across multiple optical media types in a single library, including the ability to migrate data between them. It also includes the extension of ADIC's Infinite File Life (IFL) technology to include all generations of LTO tape media. IFL is an ADIC-exclusive software feature that automatically tests the integrity of data stored on removable media and then migrates it to new media when specified error-rate thresholds are reached. E[acute accent]"Very long retention of archived data is a key task for several different kinds of specialized storage applications, including science and engineering, records retention, and digital asset management," explained Lance Hukill, ADIC Vice President of Software Sales. "ADIC's storage management software helps solve that problem by automatically testing the integrity of files and moving them to new media in order to safeguard them and by providing migration of data across multiple pieces of removable media and across different media types over time. With these new features, we are effectively providing a way for users to protect and preserve their stored data for very long retention periods independently of the media it is stored on at any given moment." E[acute accent]ADIC also announced that they have expanded the range of storage devices that AMASS supports to include StorageTek 8500 tape libraries, ADIC Scalar 10K libraries with IBM 3592 tape drives, Plasmon GX series libraries, and G-series libraries with mixed MO and UDO drives, along with IBM LTO-3 tape drives. Operating system and drive support has been updated to include IBM AIX 5.3 (32- and 64-bit systems), IRIX through version 6.5.26, and Solaris sgen device drivers. E[acute accent]AMASS 5.5 is available now from ADIC and ADIC partners.

E[acute accent]About AMASS

E[acute accent]AMASS transforms tape and optical libraries, typically considered "off-line" storage, into truly online direct-access mass storage -- enabling users, administrators, and applications to effortlessly archive terabytes or petabytes of data. AMASS presents an automated optical, tape, or DVD library as one device and one mount point, through a standard UNIX file system interface consisting of directories and files. Users or applications can save or access files residing on libraries in the same way they would with magnetic disk. For more than a decade, AMASS has helped thousands of end users manage petabytes of data on more than 100 different qualified library models and 15 separate drive types.
