Solaris Cluster, Sun Cluster Geographic Edition and Virtualization: The Art of the Possible

Virtualization is a hot topic right now. You only need look at what Sun is doing with our CoolThreads servers, our storage, our software, our Open High Availability Cluster (OHAC) HA-xVM and HA Container agent development work ... deep breath ... and our OEM agreements and I think you'll agree - it's everywhere. Consequently, it's generating lots of questions on our external cluster forum and resulting in several posts to the Solaris Cluster blog, including this one.

So does virtualization mean that the need for clustering goes away? Far from it! Now that you've consolidated your multiple, independent servers into a single virtualized platform, you've effectively put more of your 'eggs' in a single basket. If the services are mission or business critical, you are still going to need to protect them. And how are you going to do that? Solaris Cluster, of course. Oh, and what about disaster recovery? Critical services need protection against fire, flood, natural disasters. That's where Sun Cluster Geographic Edition comes in. Is your head hurting yet?

As with any rapidly evolving technology, it's important to understand the ramifications of what you are doing, as well as be able to navigate the what-works-with-what matrix. Failure in either department could result in an unsupported configuration or an implementation that doesn't achieve the levels of service you would expect.

When I first suggested to my colleagues that I would author something on this topic, I had no idea what I was letting myself in for. I can usually talk to one expert, or consult one document and get all the information I need. But as you'll have realised from the preamble, the combination of virtualization and clustering spans many boundaries. So, I am indebted to the many colleagues who provided information and reviews for the Blueprint that resulted from my rash suggestion.

I hope you find "Using Solaris Cluster and Sun Cluster Geographic Edition with Virtualization Technologies" saves you a lot of head scratching when your colleague, manager, or professor asks you, "And how do Solaris Cluster and virtualization technologies work together?".

Enjoy.

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.

CLUSTER FUN WEEK

We had a few days to do some fun activities, as a team, before our holiday break. There was a "YouTube challenge" suggested by Keith. As part of the fun, we had our creative hats on and made videos and designed TShirts with our product, as the theme. We had less then 3 days to make the videos. On thursday 21st December, the team met over lunch to view the 7 videos that were made. It was fun watching the videos created. Some of them are really fun. I am in awe of the creativity in this group!

Check one of our fun videos "Get A Life"

.

GetALife is also on YouTube. We will share some of the others as well. Some are bound to make you laugh!

Next year promises to be an interesting year! We will be back in '07 with renewed energy!

Happy Holidays!
