What is the minimum number of nodes I can install in managed mode? I have 2 nodes.

Due to infrastructure limitations, I can't have 3 nodes readily available, so I want to integrate them one by one, on average every 4 months. Is this possible? And if so, is it possible to maintain a configuration with only 2 nodes? What would be the maximum recommended timeframe?

Hi,

I have just seen clusters running, more than one year, with one node only. But if you want to have a good redundancy and failover mechanism, best would be 3 nodes.

I would recommend you reading Managed failover mechanism.

Best regards
