Two Million Lines of Code

One year ago, we announced that we would open source the entire Solaris Cluster product suite. Today, we are delivering on that promise six months ahead of schedule by releasing over two million lines of source code for the Solaris Cluster framework!

Read the official press release and listen to a podcast with Meenakshi Kaul-Basu, Director of Availability Products at Sun.

This third, and final, source code release follows the initial open sourcing of the Solaris Cluster agents in June, 2007 and Solaris Cluster Geographic Edition in December, 2007. As with the previous releases, the source code is available under the Common Development and Distribution License (CDDL) under the auspices of the HA Clusters community group on

The open source version of Solaris Cluster is called Open High Availability Cluster. Although some encumbered parts of Solaris Cluster have not been open sourced, with this release, you can now build a fully functional HA Cluster purely from source.

In addition to the source code for the product itself, Open HA Cluster includes source for the Sun Cluster Automated Test Environment (SCATE), man pages, and globalization.

Consider getting involved in the HA Clusters community group:
