OHAC as a project is dead. It's a kernel cluster, which means you need a specific build each time, and there were some discussions on the OHAC mailing list around how there are 2-3 show stopping bugs when building it against anything later than OpenSolaris 2009.06. IHAC has a long way to go until it's usable. Sun Cluster, same issues as OHAC - it's a kernel cluster. Additionally, it's future is uncertain - Oracle have made the RAC Clusterware available as a stand-alone product. Are they really going to continue supporting and developing two seperate and competing cluster products, especially with their current mindset of "everything supports the DB sales" to generate revenue from Sun? I think not. I've been playing with VCS and it looks promising, might have some stuff to report on that in the next few weeks depending on my workload. Fundamentally you have to look at what you want a cluster to provide. SC, VCS, OHAC - they're all HA cluster solutions. If you care about something so much you need to build an HA cluster for it, then surely you can afford (and need) the support to ensure it's as robust as possible. If you don't need the HA aspects, then you don't really need any of the above products - script something up to take ZFS snapshots and replicate those + basic config to a remote node. OI is fantastic, and I'm using it in production for both myself and some clients. It works great as a cluster - but in a grid or HPC solution, where you don't need HA. Right tool for the job and all that.
