Not bad ... For the SUSE HA offering we limit support to 32 nodes because after this the timing gets so critical that we can't make a support statement anymore. We do have customers with special testing / setups running ~40 nodes, but that really depends on the workload and resources you have to configure. Looks like you've found this, too. pacemaker_remote might be a chance to get more nodes, depending on the services you're running. I wonder if not a cloud solution (with some HA embedded) or a break up in smaller chunks is beneficial. It's not only about the technical capabilities but the mental capabilities of the admins limiting the reliability of such a huge cluster. Just in case, there are HPC clusters with many more nodes, but these address a total different use case. regards, Kai Dupke Senior Product Manager, HA & HPC -- Sell not virtue to purchase wealth, nor liberty to purchase power.
