Cluster Summit Recap and Photos

I'm happy to report that the first Open HA Cluster Summit last week was a fantastic event.

The summit kicked off with Professor David Cheriton's keynote address, The Network is the Cluster (pdf link). If the audience took away only one thing from the whole summit, I hope it was the point Cheriton made up-front on the second slide, that everyone needs high availability because the alternative is unpredictability and un-dependability. We all take availability of the computer services we use for granted until those services are not there. Here's a photo of Professor Cheriton concluding his talk:

As you can see the room was full and the audience attentive (I'm in the front row on the left):

After Dr. Cheriton's address, we had a discussion featuring panelists from Aster Data Systems, Google, and Sun Microsystems and moderated by Eve Kleinknecht.

One point I took away from the discussion is that high availability isn't for the 364 days a year that everything works right. It's for the one day a year when something goes wrong. Here Thorsten Frueauf (left) and I are watching the panel:

The morning session wrapped up with my talk on a minimal and modular HA cluster for OpenSolaris (pdf link). Here I am at the podium:

Lunch featured a nice centerpiece of an OpenSolaris Bible at each table for one lucky winner from that table.

I happily signed the books for all the winners.

The afternoon sessions included a variety of talks from both Sun and non-Sun participants. I particularly enjoyed Marcelo Leal's presentation on his AVS agent for Open HA Cluster (pdf link):

The event concluded with a fun "Casino Night":

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:

Tuesday Dec 04, 2007

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.

Solaris Cluster Express 10/07 is now available for download.

As usual, Solaris Cluster Express is a complete version of the Solaris Cluster product that runs on the Solaris Express platform. This release of Solaris Cluster Express runs on Solaris Express Developer Edition 9/07.

Try it out -- it's free!

At Sun Tech Days Boston

I'm in Boston this week for the Sun Tech Days conference. Today I will be giving a presentation on Open High Availability Cluster as part of the OpenSolaris track. Here's the complete conference agenda.

Solaris Cluster Express 7/07 available

The first release of Solaris Cluster Express is now available for download.

Solaris Cluster Express 7/07 is a complete version of Solaris Cluster that runs on Solaris Express Community Edition build 68. You can install and run Solaris Cluster Express 7/07 on SPARC based platforms and on 32-bit or 64-bit x86 based platforms.

As the tech lead on this effort, I'm particularly pleased that we were able to release it so quickly after our first Solaris Cluster source-code release last month.

My colleague, Thorsten, wrote a great summary of the reasons that this is a particularly exciting release.

You can also browse the installation instructions.

Please check it out and give us your feedback!

My Upcoming Open HA Cluster Talks

I'll be presenting, "Discovering Open High Availability Cluster" at two different OpenSolaris User Groups in the next few weeks.

Both meetings are open to the public. If you’re in the area, please come by!

Globalization Source for Sun Cluster Agents

We've open-sourced some more Solaris Cluster code under the Open High Availability Cluster umbrella. The globalization (G11N) source code for the Solaris Cluster Agents is now available.

News stories about Open HA Cluster

There are many other news stories, but they mostly seem to be duplicates of the above listed stories.

Open-Source Solaris Cluster

I'm excited to report that the HA Clusters community group on OpenSolaris.org went live this morning!

In addition, we released over 200,000 lines of Solaris Cluster code, including most of the Sun Cluster Agents and the Data Services Automated Test Suite, under the name, Open High Availability Cluster. This code is available under the Common Development and Distribution License (CDDL), as is most of the code on OpenSolaris. You can download the code here.

The agents and test code compiles with Sun Studio 11, which is freely available from the Sun Download Center.

We're committing to open-source the full Solaris Cluster product over the next 18 months, including the agents, core, Geographic Edition, test suites, and docs. We expect to open nearly three million lines of code! (Two million lines of product code and one million lines of test code).

I'm looking forward to working with the new HA Clusters community on future Open HA Cluster development!

Open High Availability Cluster

Regular readers of this blog may have noticed that I haven’t written much about my recent work at Sun. That silence hasn’t been due to lack of interesting material. Quite the contrary. The reticence is because I couldn’t discuss my work publicly. I still can’t give too many details, but the overview is that I’m the technical lead on the initiative to open-source the Solaris Cluster product group.

As the first public step in this direction I proposed a new HA Clusters community on opensolaris.org. To quote from my proposal:

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.

I’m pleased to report that my proposal was unanimously approved today by the OpenSolaris Governing Board. I’m excited to start building the HA Clusters community!
