Due to quorum we need minimum 3 Monitors. Does it means in GEO cluster we need 3 independent Data Centers?? One Mon per datacenter?
From a very technical perspective, yes, you would need 3 datacenters. But itÂs very common (and perhaps I could say that itÂs recommended) to have only 2 datacenters, with a ÂfauxÂ datacenter hosting the third monitor. That third monitor could be anywhere, whether in datacenter A or datacenter B, or in an isolated closet all by itself.
