Hi,

In a article by thelastpickle [1], i noticed:



The key here is to configure the cluster so that for a given datacenter the 
number of racks is the same as the replication factor.



When using virtual machines as Cassandra nodes we have to set up the cluster in 
a way that number of racks is the same as physical servers, so by losing one 
physical server just one copy of any data would be lost, right? which could be 
much greater than RF, would this cause any harm on cluster 
health/balance/availability?
