We live in a very large county and resources can be in several different buildings. While a hurricane can hurt one area pretty bad, other parts will be fine. Plus we have a DR site that's not in our area at all.

 

In every pool, there are members in the different locations. When everything is fine all LTMs have access to all the members. In the case of a hurricane, we would move the VS IP range to the cold site, which has critical servers at that location as well.

 

I hope I answered it clearly, but the simple answer is that if I picked up the config from production and placed it at the DR site (minus routing, IPs Subnet, Gateway) The LTM would have access to all pool members in South, North, Central, West county and the DR site. As we started losing buildings due to power and network issues the LTM could keep serving from the members that are available.
