OpenHACluster (OHAC) has been out for quite some time now, but with the new release of OpenSolaris a new version was required.
So, here’s a Video on OpenSolaris 2009.06 Open HA Cluster. Check it out!
Information on how to get access to it, read Nick Solter’s Blog entry about that.
Remember: Sun’s Cluster product is NOT a framework, it’s a real, ready to use, fully working product. The Open HA Cluster is just the OpenSource version of that to be used in conjunction with OpenSolaris!
