Hi Balamurugan,
Technically it is possible, but not a supported/recommended scenario. Like Jim Xu recommends is to build a HA setup. What use do you have if you put one server in other datacenter and one in a other datacenter if the whole pool will fail. This don't give
you a Disaster Recovery solution. Best practice is to build 2 separate pools and you can have a good HA and DR setup with this.
