As expected (CI No 2,705), Data General Corp has unveiled a version of its well-regarded DG/UX Unix implementation for its forthcoming Pentium Pro-based AViiONs. DG/UX 4.1 incorporates Non-Uniform Memory Access techniques to extend symmetric multiprocessing scaling up to 32 proces sors in one box and will be available in versions for both its Pentium and existing 88000-based servers cut from a single source tree. Legato NetWorker and Archiving and B2 security is included. DG/UX 4.1 will support clusters of up to eight nodes, and includes high-availability, shared file and print services and scheduling. DG/UX Cluster Software 1.0 ships in November for $2,000 and above. A distributed lock manager will cost from $5,000 to $20,000 per node. Clusters are managed from within the DG Enterprise Management Platform 3.0, which runs on a Windows NT personal computer and includes HP OpenView Windows Workgroup Node Manager and Hummingbird Communication Ltd’s Exceed X Server. DG/UX Cluster Manager 1.0, DG/UX Manager 2.1, DG/UX CLARiiON Manager 1.3 and DG/UX Graphical FileSystem Manager 1.0 run under DG Enterprise Management Platform, providing administration of CLARiiON disk arrays and enabling users to configure virtual and physical disks and file systems. Posix 1003.2 requirements break the programming model therefore Data General has said that it is likely to offer Spec 1170 compatibility as a bolt-on option in the future.
