I am trying to get my head around this, so hopefully someone can help! The example is (for me to learn):
- 2x server racks
- Rack 1 contains two nodes + one file-share witness server
- Rack 2 contains two nodes
- So 4 nodes in total with 1 FSW in a cluster
What would happen if rack 1 failed? Would the two nodes be enough in rack 2 for the cluster to stay online, or would it be the same case as with a single node and the cluster would go offline due to even numbers?
In a 2x node and 1x FWS set up, I understand if the FWS and 1x node fails then the cluster goes offline, but what if there are 4 nodes?
