We have a server-farm consisting of 4 SSO servers: 2 servers on the first site and 2 servers on the second site. We plan to shutdown both SSO servers on the first site for 24 hours to simulate unavailability due to a disaster.

What are the exact actions required to ensure SSO is remaining fully functional in this situation?
What implications there may be in respect of directory and data synchronization between the SSO servers on the first and second site?

Please note that there are several kind of data sets to be replicated:
