Recent Open HA Cluster Activity

There have been some exciting developments in the Open HA Cluster open-source community over the past couple months. Specifically:

Sun Cluster Geographic Edition is now Open-Source

The source code for the Sun Cluster Geographic Edition product is now available in the HA Clusters community on OpenSolaris.org! In addition to browsing the Open High Availability Cluster Geographic Edition source code, you can download it and build it with either the Sun Studio or the gcc compiler.

This source code release represents the second phase of the complete Sun Cluster open-sourcing roadmap. The first phase, the Sun Cluster Agents, occurred last June, and the third and final phase, the Sun Cluster core gate, will happen sometime next year.

I'm particularly pleased that, in addition to product code, this release of the Geographic Edition source includes test code, man pages, and globalization source.

Journey to Open High Availability Cluster

I am sure you have read Jonathan Schwartz's and Rich Green's blogs about Sun's Open source initiative and plans. We in Sun Cluster were just wrapping up the Solaris Cluster 3.2 release end 2006, when Nick told me that he wanted to do some investigation around open sourcing and see what it takes to do so for Solaris Cluster. One thing lead to another and before I knew it, we started the open sourcing effort for Solaris Cluster in January this year. The project was referred to as Pleiades (the open cluster of stars closet to earth).

The commitment to deliver end June seemed like a daunting task, at first, given all that we did not know.

Six months later and here we have our first release of Open High Availability Cluster. We are committed to sharing more code in the 18 months and working with the community. I encourage you to check out our HA Clusters community. You can read the feature story, which has more details on the announcement. Also listen to a podcast with Keith White.

This journey has been short and intense! The small distributed team, located in Austin, Bangalore, Colorado, France, Germany and Menlo Park, did an awesome job coming together and helping orchestrate this first release. Yet another example that demonstrates what this group is capable of doing!

I joke with Nick that only one month after returning from paternity leave he has had a second baby this year! :-)

On the Road to Open-Source Cluster Code!

To those of you who have been following Sun's software strategy, it should come as no surprise that we've been thinking about open-sourcing Sun Cluster. As the first (public) step in this direction, I've recently proposed an HA Clusters community on opensolaris.org. You can read the initial post here, and find the whole discussion in the June archives here.

To quote from my community proposal email:

Sun Microsystems will contribute to the community the source code for
Solaris Cluster, Sun's commercial HA Cluster product group, under the
name “Open High Availability Cluster.” This contribution will start at
the time of community formation with the Sun Cluster Agents source for a
wide portfolio of applications.

Stay tuned for more details!
