I'm using MongoDB and I want to know if I can add an Arbiter node in the same server that I'm hosting my Config-Server. Is it possible?
Let's say that I have 3 sharded clusters with 6 servers (2 per shard), 3 config-servers (each one will have arbiter for each shard) and 1 server as mongos (router). Is this good enough?
Also, what is the suggested specs for those Config-Arbiter servers would be?
