That wouldn't really work.  First of all we don't have Nimbus HA yet, so 
whichever colo you put nimbus in would be a single point of failure.  Even 
after nimbus HA all the state is stored in ZK, which uses a quorum to be 
functional, so whichever colo had the most ZK nodes in it would be the single 
point of failure.  If we are doing a true lambda architecture we often don't 
have a BCP for storm, as it can be down for a while and the batch will stop 
over the results.  If we are doing more of a kappa architecture it varies by 
the need.  But in those cases we will either run hot-hot and pick the result 
with the most complete data, or hot-warm and use something else to trigger the 
failover.

 Hello,
          Can Storm be deployed in a topology where the nimbus node and data 
nodes in a single cluster can span different data centers (for Disaster 
recovery scenarios)? Or is there another recommended deployment topology for DR 
scenarios?
 
Regards
