   @himanshug ,
   Yes, use multiple tiers can be an alternative for some cases, but it doesn't work in the case that you want to keep the same number of active replicants regardless of how many racks/zones that you have in the cluster. For example, there will be only one active replicant if rack B goes down in your example.
