The Santa Cruz Operation Inc launched a new version of its NonStop Clusters software yesterday, the first to use the UnixWare 7 SVR5 operating system as its base. SCO has been working with Compaq Computer CorpÆs Tandem division on the software.

Scalability goes up to 12 nodes, compared with the two currently supported by Microsoft Corp with its MSCS Wolfpack technology. SCO has added cluster API and scripting to help application developers to link up their applications. Other new features include cross-node mirroring, fibre connections to shared disk storage and new cluster management tools.

Compaq, Siemens AG and Fujitsu Europe all announced new certified hardware for the systems. SCO also launched new services offerings to support the clustering. Pricing os $4,000 per node, with services and support sold separately.
