Present configuration: Datacenter 1 (DC1) 2x MBX DAGs servers 2x CAS servers
I want to start working on replication of my EX2010 data to DC2 for DR. So, my first question is the number of MBX servers to configure at DC2. My first reaction is to only put one MBX in DC2. However all the documentation I am reading suggests that I am better off with at least two in DC2. Why? Is there a technical reason not to go with one? (split brain issues, etc). I can see the arguments (stated below). But, are there other systemic arguments not generally able to fit in these bullet points? I have pretty much made the point to myself that I need to do two already by listing these out. Am I dumb to even be asking the question because the answer is so obvious? Pros for one: * Less disk space used * Less licensing required * Less replication traffic Cons for one: * in case of failover, only one available copy of the database? * Potential corruption/loss of data because of only one live copy. Pros for two+: * Replication will continue for failover in case of DC failover. Better DR. * Able to split the load in case of DC failover. Cons for two+: * More disk space used * More replication traffic * More licensing required. ________________________________ For more information about Lewis and Roca LLP, please go to www.lewisandroca.com<http://www.lewisandroca.com/>.
