Well that is what confuses me.
It says that,"It could occur that multiple hosts are fully isolated at the same time. When multiple hosts are isolated but can still communicate amongst each other over the management networks, it is called a network partition."
How can isolated hosts communicate amongst each other over the management network when management network failure is the criteria for host isolation?
Sorry if I am not understanding the real meaning that HA deep dive is refering to but can you explain it? Sorry again.
