3 node cluster setup and 1 separate RD backup&nbsp; as slave with&nbsp; 1 node of cluster.  
total 4 servers.  
Database size&nbsp; around -&nbsp; 200 -300 GB  
Number of consistence connections/users could be - 300+  
  
2 cores with 3 GB ram will be enough on each server?

2CPU/3GB RAM would be enough for a small testing environment. You should go for 16GB or 32GB of RAM for production.
