Advanced Digital Information Corporation, the leader in Intelligent Storage solutions for the open systems market, today announced the general availability of its Pathlight VX disk backup solution. Pathlight VX 2.0 is the industry's first disk backup solution to offer disk performance, enterprise scalability, and full disaster recovery support -- all at half the cost of competitive products. Pathlight VX 2.0 is the first open system backup product to combine the capacity and characteristics of disk and tape in a single, unified system, using advanced policy-based data management technology to provide total system capacities up to 3,000 terabytes. The combined system fits into existing backup environments, presenting itself to applications as a virtual tape library that transparently includes disk elements for high performance and RAID fault tolerance and tape elements for capacity, economy, and disaster recovery. With Pathlight VX 2.0, IT managers can back up and restore critical data twice as fast as with conventional backup systems, support thousands of terabytes of data with a single system, and balance their data recovery service-level objectives against overall system costs. The policy-based management in Pathlight VX 2.0 offers the industry's first automated life cycle management for backup data, including the ability to create multiple copies on different media types to provide enhanced long-term data protection. Pathlight VX 2.0 provides throughput up to 2 TB/hour and a combined native capacity of nearly 3 petabytes. Disk storage elements range from 3.8 to 46.8 TB capacity; tape storage is provided by integrating ADIC Scalar(R) and StorageTek L-Series libraries. Single-library configurations can reach 2,823 TB native capacity to 5,599 TB with normal compression. For compliance with long-term data retention and disaster recovery requirements, Pathlight VX 2.0 responds to backup software commands by exporting application-readable media that can be restored in any standard tape drive or library.
