Probably I should avoid the term HA since this means so very many different things to different people.
Instead we should look at what the requirements really are. Generally for most of these things you need shared storage clustering and a reasonably high tolerance for application "restarts" (symptoms look like a power cycle where app starts on another system when power comes back.) This kind of thing is super easy to build with zones and zfs. Just keep your zone data on the shared storage. You will need to figure out networking but given reasonable planning that is easy too. Then you have to make a heartbeat and consensus driven failover mechanism. Again fairly straight forward and there are numerous open source projects you could use for this. Putting it all together requires a certain degree of skill and that is why you wind up paying for something like RSF-1 instead of building it yourself. If you're willing to spend the money to build this HA system you probably also want commercial support and the sanity of mind knowing that it is battle tested. Of course none of this needs the fancy kernel support that Solaris Cluster used. So it's totally orthogonal to my earlier questions. Btw we built this sort of HA solution for NFS and iSCSI at DEY (and then some!) I would love to see that work open sourced but for that to happen someone would have to first buy the IP.
