Westborough, Massachusetts-based Data General Corp has added new hierarchical optical storage systems for its AViiON Unix systems. The new storage management software within OpStar 2.0 offers users highly optimised access to large volumes of data stored on mixed-media systems using optical and other types of storage, the company claims, adding that optical disks and jukeboxes within the announcement offer twice the storage capacity at 20% to 40% price savings over its previous offerings. OpStar 2.0 is aimed at archival and imaging applications, and high-end storage applications for client-server networks. It consists of new data storage management software, with a transparent interface to the DG/UX operating system, coupled with the new family of optical disks and jukeboxes. The storage management is based on MastarMind software from QStar Technologies Inc, which integrates magnetic, optical and off-line storage media into a single, centrally managed resource. There is a new line of 5.25 erasable optical drives and jukeboxes, with capacities ranging from 1.3Gb for a single drive unit to 72.8Gb in a 56-platter jukebox at $5,000 to $35,000 including OpStar 2.0 software. The OpStar 2.0 12 write-once optical devices with 6.5Gb to 504Gb including OpStar are from $30,000 to $230,000. OpStar 2.0 is out now.
