Hi,

I think it will be worse, because each server would host a total of 100 
databases (50 "master"
+ 50 "slave" databases) :
 - Server "A" will be the master node for 50 databases, and "B" their 
slave node.
 - Server "B" will be the master node for 50 other databases, and "A" 
their slave node.

Do you think it's a viable setup ?

Thank you !
